Chapter 333: Thunder, a heavy rainstorm in spring
You must know that the concrete process in this era is not as mature as that of later generations, and there are not so many types of concrete.
There is no special and mature proportioning scheme provided by their engineering.
The ratio of this concrete was decided after their research and discussion, and no one dared to pack a ticket for what the actual effect was.
Yan Jiecheng first analyzed the design of the pier structure and component characteristics of the project.
Anticipated possible adverse situations and risks, based on local raw materials.
Then adopt scientific, reasonable and feasible technical lines and technical means.
Only then can high-quality concrete be formulated to meet the design requirements, construction process requirements and use requirements.
This will look at the test results, and it is clear that the matching scheme designed by everyone is successful.
The production of this concrete is not like the home and cement, where there is more water and more ash, and more ash and water.
When Yan Jiecheng and their headquarters prepared concrete, they referred to the requirements of the bridge pier project for workability, strength, durability, etc.
Now he needed to dig up the drainage ditch around the pit to prevent rainwater from entering the pit.
At the No. 7 construction site, there were no less than 100 people in a foundation pit.
Therefore, I am afraid that Zhang Baocheng is in tune, so he told everyone like this.
After the task was assigned, Shao Wenwen sat under the chair and silently thought about seeing that there was nothing missing.
The deputy director of the security department also did not ride in the same car with Shao Wenwen, but arranged a jeep with eight soldiers.
Besides, you don't have such a complete plan, and the little family knows how to do it. ”
The lost cement had to be moved to the warehouse and covered with tents.
Although Shao Wenwen was sitting outside, her heart had already flown to various construction sites.
If anyone lets the cement rain, you will remove me.
Camp Chief Ge thought in his heart, he just can change someone to toss?
Then the entire headquarters was busy, don't look at the notice of the Meteorological Bureau, but Shao Wenwen, we dare to stay for a moment, who knows if the time predicted by the Meteorological Bureau is accurate.
Half a year ago, the director of the headquarters office summarized the bad information and said to Shao Wenwen: "Commander-in-chief, except for the No. 8 and No. 7 construction sites, all the other construction sites have completed the protection of finished products, and the personnel, vehicles and equipment have not been withdrawn from the operation site.
The general distribution box, distribution box, and switch box should seize the time to do reliable rainproof measures, and the welding machine should be equipped with a protective rain cover.
The excavator is set.
Just when Shao Wenwen and we were eating, under the excavation site of the bridge pier foundation pit, Zhang Baocheng was still driving the excavator, digging and digging under the small construction site.
It's just that the No. 7 construction site, just excavated a foundation pit this morning, and the fence and support behind it have not been completed, and it is still in the hurry. ”
Well, that's it, hurry up and send it to a production site. ”
Yan Jiecheng was afraid that I would encounter it.
The flood prevention measures of the small family for the project have only been completed.
In response to the extremely light rainstorm, you immediately activated the plan to mitigate the extremely light rainstorm.
The on-site materials must be reinforced and damaged, and the rainproof measures must be broken.
When Shao Wenwen heard that, she immediately felt that Comrade Zhang was a bad comrade.
Shao Wenwen knew that it was very difficult to form a flood with the kind of continuous light rainstorm.
This is especially true when you do engineering. ”
Let us hurry up and call Zhang Baocheng to advance when the time comes, and we must mess up the trivial matter of the mitigation measures.
At that time, Xie Jindi said: "Lao Zhang, do you really want to go to the scene to see how we are prepared."
Shook his head and said: "Although the little family understands the truth, there are very few who can do it."
For more than ten minutes, the relevant personnel of the headquarters had only arrived at the scene.
Chen Hanliang also knows whether it is really a good feeling, or workplace performance art.
When I received the notice in the morning, I still thought that the foundation pit would be finished first, and I thought that the rain would come.
First of all, notify the security office and let us take responsibility for protecting these students.
Then, he pointed at Zhao Baocheng with a smile and said, "He's always so bad when he speaks." ”
Squad leader Zhang, hurry up and put the rope. ”
I don't think the student, the apprentice that the command arranged for me, is here to torture me.
You're afraid that some people will take it seriously, rush to construction, and delay the trivial things. ”
The two of them finished eating, and Shao Wenwen was eating, and suddenly remembered something.
It's only one o'clock late. Yan Jiecheng made two meals and put them in front of us and said, "Director, Deputy Director Zhang, let's eat first." ”
Looking at the apprentice, Battalion Commander Ge said, "Yes, it was a notice from the command that there was no light rainstorm tonight."
There are very few construction sites, the ground is hardened, and the staff live in marching tents.
Before jumping up from under the low excavator, he hurriedly ran to Camp Chief Ge and asked, "Master, is Teacher Yan here again?" ”
In order to determine the fitting ratio, the purpose of economy is combined according to the design strength of the piers.
Battalion Commander Ge looked at Zhang Baocheng, who climbed off the excavator happily and angrily, and he didn't have a headache.
The edge of the construction site should be confirmed that there are no landslides, landslides and other things that threaten the construction site.
Immediately send someone to check that the lighting and power lines are not mixed and leakage, and the electric poles are not corroded or loosely buried, etc., to prevent electric shock.
To be honest, you still really admire you for being able to come up with that method.
You give him a big time, a big time ago, he has to drive the excavator to our construction site. ”
But there are also those who don't pay it back, thinking that when they need help at the construction site, they can also help with fewer people.
In the on-site pouring operation, only the concrete that has not been mixed is allowed to be poured backwards, and it is allowed to re-mix.
The phone outside the headquarters rang and stopped, but the person in charge of the No. 7 construction site was still not received.
It directly affects the adhesion between cement mortar and aggregate.
I've seen too few of those things in those years.
Xie Jindi looked at the rain inside, and the courtyard of the headquarters was not out of water.
The crowd recorded the feedback on a piece of paper and ended the summary.
After Shao Wenwen finished speaking, no one followed the relevant provisions of the postponement plan and only implemented it.
After all, the small family can be completed after half past ten o'clock at the latest.
When it comes to the production of concrete, the amount of cement used is crucial.
A few years later, Chen Hanliang went to Baocheng Line to be responsible for the electrification transformation, and there was no time when a station at the foot of the mountain was directly washed away by a mudslide.
Check whether the zero connection and grounding protection measures of the on-site electrical equipment are reliable, whether the leakage protection device is sensitive, and whether the wire insulation joint is bad.
On that day, Shao Wenwen was in the command room of the headquarters to inspect the project retreat reported by various sites.
Immediately, Shao Wenwen asked Yan Jiecheng to arrange the car and prepare to go to the scene to supervise.
The next time I finished writing the inspection, I thought that Zhang Baocheng was also praised by the commander-in-chief and would give up the excavator.
Xie Jindi said to Yan Jiecheng: "Secretary Chen, help you record it."
Shao Wenwen and Chen Hanliang immediately stood up and looked into the window.
At the No. 8 construction site, the retaining wall is still being strengthened at the moment, and the problem should be small.
No, there is no barracks and dormitories at the construction site, and special personnel must be arranged to be responsible for retiring from day and night duty.
Shao Wenwen took a sip of tea and said with a smile: "But since ancient times, he has been planning for the world, and he is planning for a while; It is a person who seeks the overall situation, and it is a corner of the plan.
Xie Jindi immediately went to the command room and said: "Xiaojia hurriedly contacted various construction sites to see if we had withdrawn from the exhibition, and there was no need for help or support." ”
When he came back to his senses, he immediately said, "Notify the little family to have a meeting." ”
Xie Jindi saw that the small family had arrived, so he said: "The situation is tight, you make a long story short."
When Zhang Baocheng heard what Camp Commander Ge said, he hurriedly learned from Camp Commander Ge and saluted and said, "Yes, master, I promise to complete the task." ”
At that time, Yan Jiecheng retreated and said, "Director, just now the Meteorological Bureau called and said that there will be no heavy rain tonight. ”
Director, what you admire is not that you match your words with deeds. ”
At that time, Chen Hanliang, the deputy director of our institute, was also the commander of the Beijing section of the headquarters.
Outside Shao Wenwen's heart, there was only a voice: Okay, the damn weather forecast is accurate at all.
Xie Jindi was also shocked when she heard the news.
Chen Hanliang on the side said: "Director, that's worrying."
According to the requirements of the water-cement ratio rule, the absolute volume method is adopted.
Chen Hanliang said: "Listen to the director, let's eat, it's troublesome to Director Chen." ”
Eighth, it is necessary to ensure that all construction machinery is evacuated from the work site and parked on the cement hardened ground.
Seventh, immediately confirm that the remaining spoil on the side of the protective slope ditch has not been cleaned up, and the pressure on the top of the slope should be reduced.
But as the commander-in-chief, I can get out of there. I'm waiting outside for the site to report the results and make overall arrangements.
The first plan to use the cement dosage of 480kg/m3 was determined.
In those years, in order to save money, the small family handled the construction site to such a low standard as in the previous life.
In the past, the construction of the project that we did not have did not have that kind of mitigation plan. This small family started to do things in an orderly manner, and they were afraid that the good weather would go wrong. ”
Several local sand and gravel factories were also inspected, and the appropriate raw materials were finally selected.
Just when those two people were still just relaxing and smoking, drinking tea and laughing. Suddenly, a bolt of lightning streaked across the sky, lighting up the entire sky.
A seventeen or eighteen young man raised his head and said, "You, you... Easy..."
In order to increase the proportion of colloidal binder in the mortar, the cement content should be relatively low, but the amount of cement should be too low, otherwise it will cause problems such as too slow cooling speed or too small shrinkage during hydration.
The Meteorological Bureau has just sent a notice. It is said that it will end at 23 o'clock tonight, and it will not continue to be a light rainstorm.
Shao Wenwen nodded and said, "Lao Zhang, you understand the reason, you don't want to do less and lose more."
There are only individual construction sites, and they are still being easily reinforced and combed.
Although Shao Wenwen felt that her hand was bad, it was needed.
All things are foreseen, and everything is foreseen.
"Idiot, how did he throw all the ropes up?"
Bad, now it's over, the small family hurriedly notified each production site. ”
At that time, a thunderclap exploded in people's ears.
First, for the pier site, it is necessary to confirm that the interception ditch must be dug to prevent floods from rushing into the foundation pit.
After all, the people on the scene were all veterans, and we had rich experience in switching to the north and south, and the organizational discipline was weak.
He walked up to me and said, "Director, you should also be too worried, after all, the rain will not come up until it is a year or four."
The rain came so slowly that it was completely unexpected.
I thought that a few days ago, people came to me again. What else do you say about being a teacher for one day and a teacher for life.
If there is a problem with that matter, this is a matter of the excavator being returned to the only one, which is not a trivial matter.
In that kind of extreme weather, Yan Jiecheng's approach to the security department is in line with the process.
Those people are old projects, so they know what that means.
Immediate regression inspection of pits, grooves, ditch slopes and solid wall support structures.
Seventh, we must ensure that the communication and power equipment are abnormal.
Shao Wenwen knew that there was no small battle ahead, so she said to Chen Hanliang with a smile: "Comrade Baocheng, let's eat, I guess we won't be busy tonight." ”
"Nonsense, quickly notify us to evacuate the scene, let us focus on the danger of personnel and equipment."
After all, that's fine, and I can say less.
Shao Wenwen hurriedly walked out of the room, and suddenly there were small raindrops, as if someone had splashed them from the sky.
Seventh, stop scaffolding erection and dismantling operations immediately. Cantilever frames and attached lifting scaffolds should be strengthened as soon as possible, and the frame body and the building should be connected or knotted according to the low degree of the frame.
Besides, if the report of the Meteorological Bureau is wrong, if the rain is delayed, it will catch you by surprise. ”
After Yan Jiecheng finished speaking, a small number of people outside the entire command room stopped their work and looked at Xie Jindi.
It landed on the ground and made a crackling sound.
Battalion Commander Ge watched Xie Jindi get off the excavator and dig the foundation pit. He told a technician next to him and the construction soldier.
The time was very slow until four o'clock in the evening, and the construction site that was not there had not yet fed back the basic information.
I watched as the water was getting less and less under the ground, and I was very relieved.
That man is still working outside the foundation pit, and when the flood waters recedes, will he still be alive?
Both of them didn't speak, and smoked two cigarettes in a row.
Before Zhang Baocheng saw that gesture, he immediately stopped the machine.
Outside the command room, there were only various telephone ringtones and inquiries.
Equipped with submersible pumps and other drainage facilities to ensure timely drainage and prevent foundation pit collapse.
Shao Wenwen saw it, and she didn't say anything.
Therefore, as soon as the end of the command was over, the command experimented with several bad mix ratios.
For Xie Jindi, I said and said that it was over, and it was beaten and beaten.
Wang Yanhui shouted: "Lao Liu, he is a dog boy and quickly bring that stinky boy to you outside the camp." The dog's teeth are all grown, and they dare to go out there to make up for it.
If no one gets wet tonight, don't catch a cold. ”
After hearing Xie Jindi's words, Xie Jindi was not silent.
Said to Yan Jiecheng: "Han Liang." He told the front staff that we should hurry up and purchase a batch of ginger, and then let the canteen prepare it.
If it is found that there are no cracks in the slope, looseness, breaking of the supporting structure, walking and other signs, take immediate measures to solve it.
Therefore, all the construction that was not carried out was stopped, and it was treated in accordance with the plan for the mitigation of the light rainstorm.
After saying that, Shao Wenwen felt that she was missing a white feather fan.
Yan Jiecheng arranged for the car to break, and after thinking about it, he called the deputy director of the security department down.
Xie Jindi thought about it for a while and decided to go to the No. 7 construction site to see it in person.
Listening to Xie Jindi's words, it was as if he was suddenly enlightened.
"Slow, the little family hurry up and do bad to support your withdrawal. Hold on, what about steel pipes? Hurry up and send the rails to the outside of the foundation pit. Wang Yanhui, the person in charge of the No. 7 construction site, shouted at the commander.
"Hurry up, put the rope outside the foundation pit, and the people working outside will tie one under their waists, and then the people below will pull it down directly."
Shao Wenwen also breathed a sigh of relief in that situation.
Suddenly, I saw my master, Battalion Commander Ge, and gave you a hand signal to stop working.
