???? It took five full days for the roadbed garbage to be transported and cleared, and it rained twice in the process. "Co*music*words*love*first*hair(http://www.klxsw.com

Shu Cheng wondered, it was the end of December, and it was still raining a lot, this weather was extremely abnormal, and it could even be said to be too abnormal.

In the winter of Taishi, it is generally about minus 10 degrees, and the recent temperature is at most minus 3 degrees, which makes Shucheng feel weird.

From now on, it will only be forty days until the end of the year.

These days, Zhang Tianhu has come to the construction site several times, and his meaning is obvious, hoping to complete the construction of the eight-character wall after the flat reform of Shangyunzhuang was completed a year ago.

For the roadbed, Zhang Tianhu's requirement is to complete all the filling, and after the New Year next year and come back in February, the construction team of the station renovation can directly enter the site.

In this way, the delay of the construction period is less, and the requirements of the construction points can be fully met.

On April 25, the preparatory work for the transformation of the station began in mid-February, and there was no problem in terms of time, which could meet the requirements of the construction period.

"Minister Shu, you see that the frame is about to be capped, is the material equipment you erected on the beam, are you preparing some materials?" On this day, Zhang Xiaoyun looked at the workers who were tying steel bars, and suddenly said to Shu Cheng.

Once the main body of the frame culvert is poured, it will take up to three days to remove the formwork and complete the construction of the waterproof layer on both sides of the culvert roof, and the jacking construction can be carried out.

As for the scaffolding and formwork in the culvert, it is completely possible to jack in and then dismantle.

Before jacking construction, it is necessary to erect a temporary beam.

The length of the beam is 12 meters D-type construction beam and 24 meters D-type construction beam, which is generally used more in the existing line jacking construction.

Depending on the width of the culvert, different lengths of construction beams can be selected.

Shangyunzhuang's flat renovation is a culvert of 1-8 meters, and when using a temporary beam, it is necessary to use a 24-meter D-type construction beam, and the length of a 12-meter D-shaped construction beam is not enough.

Because in the construction process, not only the width of the culvert should be considered, but also the grading, the five-meter height grading, according to the one-to-one grading, at least 20 meters to meet the requirements.

The function of the construction beam is to overhead the existing line, so that the soil under the line can be excavated in order to carry out the jacking construction of the culvert.

To put it bluntly, the function of the beam is to lift the railway, without affecting the movement of the train, it can still pass, dig out the roadbed issued by the railway, and there will be no safety accidents on the railway, so as to meet the conditions of opening to traffic during construction.

When Zhang Xiaoyun said this, Shu Cheng also agreed, and said, "Team Zhang, you say, I will write down what you want." ”

Although Shucheng is very clear about what is needed in the jacking construction, he does not want to pretend to be forced, to be honest, Shucheng has always been relatively low-key, many times, the technicians ask the person in charge of the construction site, it is very necessary.

Who knew that hearing Shu Cheng say this, Zhang Xiaoyun said: "You are the deputy minister of the Ministry of Technology, you should prepare it yourself, and discuss it together when the time comes." ”

Listening to Zhang Xiaoyun's tone, he didn't want to sue Shucheng, and wanted Shucheng to prepare by himself.

Shu Cheng one day, pondered for a moment, and said: "Team Zhang is not as good as this, I will write to you what I want to prepare, see what needs to be added?" ”

Seeing that Shu Cheng was so modest, Zhang Xiaoyun couldn't go too far, nodded and said, "That's fine." ”

In Zhang Xiaoyun's view, it is almost impossible for Shucheng to prepare all the materials in the construction, and it is great to be able to prepare eighty percent.

Moreover, it is completely impossible to prepare these materials without half a day, and even Zhang Xiaoyun may forget some of these materials.

To Zhang Xiaoyun's surprise, Shu Cheng directly opened the notebook he was carrying, found a page that was not written, and began to write.

Zhang Xiaoyun was stunned for a moment, but he didn't care, after glancing at it, he turned to other places and stopped paying attention, Zhang Xiaoyun didn't think that Shu Cheng could prepare many things on the spot.

At this time, Shu Cheng's mind was also rolling, thinking about what materials were needed in the construction, because there was no construction digging pile in Shangyunzhuang, the support point of the beam, only one and a half meters of deep concrete was poured, and the sleepers were padded on the concrete.

Then the sleeper can not be missing, even if there is a digging pile support, the sleeper can not be missing.

After a rough calculation in the notebook, Shu Cheng wrote down 30 sleepers of 1.25 meters and 12 sleepers of 0.8 meters. 20 0.6m sleepers.

The sleeper is used to make a backing board under the beam, and with the sleeper, Shucheng has prepared some hardwood boards. 20 pieces of size 26 hardwood planks are prepared, 30 pieces of 206 hardwood planks are prepared, and 30 pieces of 26 hardwood planks are prepared.

These hardwood planks are used between the sleepers for leveling.

Subsequently, Shu Cheng kept writing in the notebook, writing and thinking, writing for five minutes, and also writing a page, Zhang Xiaoyun didn't pay attention at first, but when he inadvertently looked at Shu Cheng's notebook, he was dumbfounded, these things listed by Shu Cheng, each item can be used, and even the number of preparations, it is very thoughtful, and suddenly, Zhang Xiaoyun looked at Shu Cheng's eyes, and it was different.

I saw Shu Cheng writing in his notebook: 2 wire ropes (diameter 5, length 35 with rope cards 12), 700 sets of wire (14), hoisting belt (with two hooks, 101 long, 20 crowbars, 20 forks, 15 shovels, 2 bundles of hemp rope, 1 thin brown rope 30 feet, 1 450 live wrench, 1 road nail hammer, 4 double buckle starting machines, 2 hydraulic starting machines, 4 top picks (100t), 15 pickaxes, 2 small bee tamping machines, 1 tamping machine, Felt sheet (8200 wide cable protection pipe 80 square feet 1, iron wire (No. 12) 1 bundle, ballast 20 square meters.

When I wrote this, Shucheng stopped, these things can generally meet the requirements of jacking construction, but there are some auxiliary things, Shucheng is not listed.

About a minute later, in Zhang Xiaoyun's shocked eyes, Shu Cheng wrote in his notebook again.

I saw Shu Cheng writing in his notebook: 1,500 woven bags, 25 bamboo rows of 50 square meters (111.5), 1 slow room, 1 table, 1 chair, 1 row plug (multi-head), 2 large buckets, 2 large kettles, 8 boxes of 200 fluorescent lamps (100w) with lighting wires, 50 kilograms of gasoline, 1 box of stone pens, and 20 pieces of insulating large rubber.

Writing this, Shu Cheng felt that there was only so much he could think of, and these preparations, ninety percent of the jacking construction, were completely satisfied.

Then Shu Cheng thought that the digging pile here was poured on site, and after pouring, he needed to put on the beam immediately, and at the end of the notebook, he added 20 bottles of an early strength agent.

After writing, Shucheng from the end of the day to the end of the inspection of both sides, at the same time to estimate the number of each kind of preparation, in the end is not enough, at this time, because the erection of the beam is also the point of construction, rather than more preparation, can not be less prepared, once the preparation is less, it is easy to have an impact on the main points.

After checking that it was correct, Shu Cheng handed the notebook to Zhang Xiaoyun, who stayed beside him.

At this time, Zhang Xiaoyun was completely shocked by Shu Cheng, there were so many things that Shu Cheng had prepared, even he didn't expect it, it can be seen how meticulous Shu Cheng was prepared!

From on-site use to on-site service, everything is ready.

Seeing Shu Cheng handing the notebook to himself, Zhang Xiaoyun glanced at Shu Cheng deeply, his face pretended to be calm, but he thought in his heart: I don't believe you have all the preparations, see if I don't find your missing items!

Zhang Xiaoyun took the notebook and began to look at it seriously, looking more carefully than Shu Cheng.

And the whole process of material preparation, Shucheng only took less than a quarter of an hour!

Only those who have really done the preparation of jacking construction materials will know how terrifying it is to prepare all the things needed for jacking equipment in a quarter of an hour!

It's like a person who runs the 100-meter hurdles in five seconds, which is twice as powerful as Liu Xiang.

Zhang Xiaoyun took the notebook prepared by Shucheng, and read it three times from day to end, in the project, Zhang Xiaoyun did not find the missing place in Shucheng, if it can be changed, at most it can only be changed in number.

But when Zhang Xiaoyun wanted to change the quantity, he once again found that the number of materials prepared by Shucheng was also very suitable, which made Zhang Xiaoyun a little convinced.

In the end, Zhang Xiaoyun had to say in an appreciative tone: "Yes, then report it according to what you have prepared, it's very comprehensive!" ”

"Okay Team Zhang, by the way, how long will it take for the roadbed to be cleared?" Shu Cheng took back the notebook and changed the subject.

In the past two days, the garbage was still being transported, because the rain delayed a day, and the meter clearance work was not carried out much, Shucheng was ready to wait for the completion of the meter clearance, and when the roller entered the site, let the laboratory Peng Hu take the drill to the construction site to test the bearing capacity of the foundation, which is also required by the supervisor Han Zhao.

"It's up to God, if it doesn't rain, it can be cleared in two days at most." Zhang Xiaoyun said.

"Cheng, then I'll contact the test first, let them send the instrument over, and when the roller enters the field, the bearing capacity can be tested at any time after pressing the original pavement, and Han Gong asked for the test before the start of work." Shu Cheng nodded.

Due to the complete decoration of the signal building, Han Zhao could not find an excuse to ask Wan Yong for cigarettes, so he had to stretch out his hand to the roadbed, as for Lao Yan's side, Shu Cheng had already agreed with Lao Yan that when the frame was capped, get a cigarette for Han Zhao, and invite Han Zhao to have a meal by the way, so as not to make trouble for Han Zhao.

ps: Originally, the jacking preparation would not be written in such detail, but then I thought about it, many peers are reading this book, so I will write down the things that need to be used in the jacking construction, and write about the approximate number, and you can follow these as a reference if you need it. If you don't know the role of some preparations, you can consult the deputy manager or operation team leader who has done topping, they should understand it very well.
