Chapter 20 The answer is like a stream
At more than 2:50 in the afternoon, the relevant personnel of the quality inspection station arrived on the date.
Looking from afar, I saw five cars slowly driving towards Pier 1.
The first one in the row was a Mitsubishi off-road vehicle, and Shu Cheng could see at a glance that this car was the car of manager Zhang Tianhu.
Behind the Mitsubishi off-road vehicle, there is a commercial vehicle, Shu Cheng is not familiar with, and the person sitting in it should be the relevant personnel of the quality inspection station.
Behind the business car, followed by a cheetah, judging from the license plate, this car should be Jianzhi, that is, the owner's car, followed by Jianzhi car is a cheetah, is the car of the supervision station, and the last one is a Volkswagen off-road vehicle, but this car is Wei Jian's car.
Five cars, kicking up a puff of dust, drove into the construction site, and it was magnificent.
After parking, the car door opened, just as Shu Cheng thought, but there were not many people who came to check at the quality inspection station this time, only three people.
There were three people from the construction finger and one person from the supervision station, which was the deputy director Qian Zong, and then the project manager Zhang Tianhu and the deputy manager Wei Jian.
Zhang Tianhu is of average stature, although there is the word Tianhu in his name, his appearance is very gentle, with a pair of eyes on the bridge of his nose, fair skin, tall and thin, to the appearance of a weak scholar.
Under the guidance of Zhang Tianhu, everyone entered the construction area in a mighty manner.
When the five cars stopped, Zhang Xiaoyun and Shu Cheng had already walked up.
Zhang Tianhu first introduced Zhang Xiaoyun and Shu Cheng to the leaders of the quality inspection station, and after shaking hands, everyone walked forward together.
After Zhang Tianhu's introduction, Shu Cheng knew that the person from the quality inspection station was a deputy director, surnamed Li, and the other two were section members, one surnamed Ma and the other surnamed Peng.
"How many piles have you done here?" Director Li asked.
"Six have been poured and two are under construction." Shu Cheng replied.
As everyone walked forward, they came to the steel bar processing area, at this time, there was only one pile foundation left in the finished steel cage, and the others had already been transferred by Lu Tao.
It is the steel cage of this pile foundation, which is also covered with a tarpaulin.
At this time, Lu Tao's workers were also working, but they were cutting the material, and did not do things such as welding steel bars.
"How many meters is the foundation of this design?" The horseman asked.
"The pile foundation design is 23 meters, and the reinforcement cage is 24 meters." Shu Cheng replied.
"Are you all welding on site? Decentralized in four sections? The horse worker at the quality inspection station asked again.
"Yes, because the crane cannot be used near the business line, you can only use the drill rig to lower the steel cage, more than six meters, it is difficult to get down, can only be divided into four sections, on-site welding." Shu Cheng responded.
Shu Cheng said, Director Li and the other Peng Gong lifted the tarpaulin and looked at the steel cage covered by the tarpaulin.
"Well, the spacing control of this steel cage is still good." Director Li glanced at the tendons of the steel cage.
Indeed, as Director Li said, in order to cope with the inspection, Shucheng specially put this better-made steel cage outside, just to cope with the inspection of the quality inspection station.
"It's better than the steel cage at the K67 site." Deputy Director Qian Zong also stepped forward.
The K67 construction site is also a bridge reinforcement, but it is not Shucheng City, but the scope of the jurisdiction of Vice Minister Guo Tao, for the inspection of the K67 construction site, Shucheng also understands a little, and listens to Manager Wei that the inspection of K67 and K45 is not very optimistic.
"Director Li, you see, there are very few steel bars that bite the meat, almost all of them are bright and round, and there is no bite of the main tendon." Mr. Qian continued.
The so-called meat bite, or bite tendon, refers to the situation that after welding the steel bar, the steel bar is scorched, and there are pimples and depressions, which is called meat biting.
"Well, it's really better than K67." After Mr. Qian finished speaking, Zhang Tianhu and the others, as well as the leaders of the suggestion, also said with a smile.
After everyone looked at the steel bars again, they continued to walk towards the construction site.
The first thing that is close is the pile foundation construction, and when the leaders of the quality inspection station come to the site, the pile foundation construction stops and waits for their inspection.
"Check if the lead line is correct, and test the specific gravity of the mud." Director Li came to the pile foundation and commanded.
"Xiao Shu, you go to test the specific gravity of the mud, you take the construction line and review the lead line." Wei Jian also arranged.
When he said you, he was referring to the pile foundation workers of the construction team.
For the three-piece set of mud specific gravity, Shucheng has long been ripe.
He took out the instrument that had been prepared a long time ago, took a part of the mud, and began to test the specific gravity of the mud, because the pile foundation has not yet become a hole, after the test of Shucheng, the specific gravity of the mud is 1.33, according to the geological conditions here, in the drilling process, this value is still in line with the requirements.
This number is almost no different from the value that Shu Cheng tested at the end just now.
Subsequently, Shu Cheng did a little bit about the sand content and consistency, because there is still a sand layer below, the sand content is relatively high, up to 4.2%, and the consistency is also slightly high, more than 24s, reaching 28 seconds.
In the process of drilling, the test of the mud three-piece set is unqualified, which is also very normal, and there is no punching yet, if the drilling process, the test of the mud three samples are qualified, then there is a problem.
"Where's your drilling record?" After the Shucheng test, the leader of the quality inspection station did not say anything, after all, the pile foundation has not been punched yet, and in the absence of punching, the three types of mud tests, these values are still in the past.
"Oh, over here." As soon as Shu Cheng heard this, he ran to the back of the drill and handed the drilling record sheet hanging behind the drill to the horse worker of the quality inspection station.
He took a closer look at the borehole record sheet and asked Shu Chengdao; "When do you test the specific gravity of the mud during the drilling process? How is it controlled? β
For this question, few people can answer it all, if it was Shucheng in the previous life, it really can't answer it completely, but for the current Shucheng, it is very easy.
Hearing Ma Gong's words, Shu Cheng took out a stack of things from Wen JiΓ n's bag, straightened his thoughts, and replied: "First of all, at the beginning of drilling, that is, when we make pulp, we will test the specific gravity of the mud once, you see, this first time is tested during pulping. β
The so-called slurry is to use loess to make mud in the process of drilling, and the purpose of mud making is to prevent hole collapse.
"Subsequently, we usually test the specific gravity of the mud once every two hours or so, and when the geological conditions change, we will also test it once, you see, these are the values tested in about two hours, and these are the values that I test after the geological conditions change." Shu Cheng pointed to the value on his mud specific gravity record sheet and said: "Every time I test, I have remarked in the back, even the geological situation, there is a record, the first time on it is soil, three meters starts, it enters the sand layer, and then when it reaches thirteen meters, it begins to enter the mudstone layer." β
Shu Cheng carefully introduced the number jΓΉ according to the mud specific gravity test record table.
It can be said that in the process of explaining the specific gravity test of mud, it is easy to forget about the need to test when the address changes.
Hearing Shu Cheng's words, the horse worker nodded slightly, took the mud record sheet in Shu Cheng's hand, took a photo, and returned it to Shu Cheng.
Subsequently, Director Li and others looked at the mud pool and the excavated No. 6 foundation pit.
No. 6 foundation pit is just in the erection of the formwork, the formwork is erected, but it has not been reinforced, after reading it, there is no problem, for the problem of punching distance on the stone, Shucheng specially gave the quality inspection station to see the change book of the design institute, and they did not say anything.
After this lap, the quality inspection station did not find any problems.
At this moment, Peng Gong of the quality inspection station said: "Your mud pool can't be protected like this, and it must be built with bricks, after all, this mesh protection is not very safe." β
For Peng Gong's words, it is indeed true, according to the specifications, not only a mud pool, but also a sedimentation tank, but the on-site construction conditions are limited, and it is impossible to cover everything.
And Peng Gong said that the mud pool should be built with bricks, but it also makes sense.
"Old Wei, you arrange some people to use some bricks to surround the mud pool." Zhang Tianhu also commanded.
"There is also the wind rope of the impact drill, which cannot be pulled only one, but must be symmetrically obliquely pulled!" At this time, the horse worker also spoke.
When Shu Cheng heard this, he suddenly realized, before he thought again, what did he ignore, he was reminded by the horse worker, he sounded, the impact drill set the wind rope, and it really had to be pulled, not just one.
"Okay, leader, I'll have someone pull another one on the other side when the time comes." Zhang Xiaoyun said.
Subsequently, Director Li took a look at the construction site again, and found no special problems, so he got into the commercial vehicle.
This inspection at the quality inspection station can be regarded as a successful conclusion.
For the two problems raised by the quality inspection station, the rectification is also simple, if the quality inspection station comes once, not even a single question can be raised, then it can not reflect their ability.
There are two problems, which can be regarded as saving some face for them.
Manager Zhang Tianhu and others accompanied the members of the quality inspection station to leave the construction site, leaving only Wei Jian behind.
"Not bad, at least there are no quality issues." Wei Jian said with a smile.
"How can it be, quality problems will definitely not appear." Zhang Xiaoyun also said.
"By the way, Xiaoyun, in two days, Lao Zhao will get two more impact drills, and the leader will ask to speed up the progress." Wei Jiandao: "But we must pay attention to safety and quality, we must not have an accident, I would rather work slowly than have an accident." β
"Well, I know the leader." Zhang Xiaoyun said.
"Xiao Shu is good, at least you have technical problems, you are back well." Wei Jianwang praised Shu Cheng.
"That's what I'm supposed to do." Shu Cheng said with a smile.
These are all small questions, if Shu Cheng can't even answer these questions, the chief worker in his previous life is really in vain.
"At the beginning of next month, the project department may have to move some people over, and the Changhan of Haocun Station here is about to start construction, and after the construction of the Changhan, the roadbed of Haocun Station is also filled, and the roadbed is not required to be requisitioned, and the leader means to fill in first." Wei Jiandao.
Hearing Wei Jian's words, Shu Cheng frowned slightly, if Shu Cheng is not mistaken, starting next month, Wei Jian will also move to the construction site to live, and the technicians who came with him, as well as Guo Tao and Zhang Min.
As the deputy minister, Guo Tao is in charge of the technical work of the three stations and two sections.
It was the arrival of Guo Tao that something would happen, and at that time, because of the unfavorable problems solved, it brought a lot of losses to the project department. xh118
