When he heard the name Zhang Wei, Shu Cheng was also relieved, since this guy offended himself last time, he actually dared to sue himself in front of Ren Changhong. Pen? Interesting? Pavilion wWw. ｂiquge。 info himself asked him to stay in the office all the time to write materials, and he never even went to the scene.

I don't know how to do it tonight, Hao Hongwei actually let Zhang Wei go to the scene, isn't this the rhythm of the pit people!

"How do you arrange Zhang Wei to be on duty tonight?" Shu Cheng didn't blame Hao Hongwei, but asked.

"Wang Guangjian and Liu Tao have both gone home, and there are not enough personnel in the technical department, so they can only arrange for Zhang Wei to be on duty." Hao Hongwei replied.

Hearing Hao Hongwei say this, Shu Cheng remembered that the two of them left yesterday.

"Oh, how long has this happened, what the construction team has tried." Shu Cheng asked.

"In fact, the catheter couldn't be pulled out an hour ago, Zhang Wei was afraid of taking responsibility, so he didn't dare to say it, just now the construction team called me, and I found out, so I immediately called Brother Shu." Hao Hongwei introduced the process again.

For the failure to report accidents, there are often in the engineering unit, and some things can be handled, and you can indeed choose not to report and solve it by yourself, which can also avoid a lot of trouble. But if you can't solve the problem and can't cover it up, this kind of thing must be reported, because once you miss the opportunity, many things cannot be undone.

It's like an hour ago, the concrete may not have solidified, and the conduit may be pulled out by other means, but after so much time, the concrete has solidified, and everything is in vain.

"This kid is okay enough, do you know the specific situation on the scene?" Shucheng Road.

"It's not clear, I'm on my way to finish the construction site."

"Okay, you tell me the specific situation later, it's really not okay, I'll go back to the project department, and now I'm in Taizhou." Shucheng Road.

"Okay, Brother Shu."

After Hao Hongwei finished speaking, he hung up the phone.

"What's the matter, Xiaoshu, is there something wrong with the project department?" Zhao Huawei frowned slightly when he saw Shu Cheng finish the call, and couldn't help asking.

"A little thing, see if the scene can be solved, if it can't be solved, I will go back in a while." Shu Cheng smiled.

"Oh, that's good." Since Shu Cheng didn't say it, although Zhao Huawei was the commander, he didn't ask.

In fact, it is normal for people to die at the construction site, not to mention that if there are some small problems, Zhao Huawei doesn't care.

Shu Cheng then accompanied Liu Jiangshan and Zhao Huawei to eat supper, in fact, it was not about eating supper, in the entire hall, there were many maids wearing stockings, wearing revealing clothes, and carrying rabbits, walking around, some with plates, some completely performing on the spot, and the scene was still quite hot.

If you like, as long as you spend money, you can play how you want here, and the service is absolutely in place.

Before the supper was finished, Hao Hongwei called Shu Cheng again.

"Brother Shu, I arrived at the site, and the construction team said that three truckloads of concrete were poured and the conduit was not pulled, and now the conduit is directly discarded and cannot be pulled out." Hao Hongwei said.

"......" Shu Cheng was directly speechless: "The three cars of concrete haven't even pulled out the conduit, Zhang Wei is stupid, and the construction team is also stupid?" I've done so many piles and I don't understand. ”

One meter of pile foundation, a car of concrete to load 12 square to calculate, three cars of concrete down, the pile foundation will come up almost 30 meters, the depth of the conduit is more than 28 meters, buried so deep, it is strange to be able to pull out the conduit!

Don't say that the concrete has set, and even if it hasn't, it's difficult to pull it out.

"The construction team said that it was requested by Zhang Wei, saying that it would be poured directly at one time, and the catheter would be pulled out at one time, which would save time." Hao Hongwei continued.

"Is it finished?" Shu Cheng asked.

"Not yet, the pile length is 36 meters, there is still one meter to the design elevation, including the pile head, there is a depth of two meters, and now the concrete can't go down, it's all in the bucket, what to do now, is it to use a percussion drill to re-drill." Hao Hongwei told Shu Chengdao about the situation at the scene.

Shu Cheng thought for a while, and finally said: "I can't pour it, let's unload the bucket first, you wait for me for an hour, I'll come to the scene to take a look." ”

After all, Shu Cheng is the chief engineer, the problem that the on-site technical person in charge can not solve, Shu Cheng has to go out in person, in fact, the position of chief engineer, if the technical minister is capable, the chief engineer is also easy, once the technical minister does not understand, then the chief engineer will be tired a lot.

Just like now, if Shu Cheng is still the Minister of Technology and Zhou Yang is the chief engineer, if Shu Cheng arrives at the scene, according to the situation on the spot, it can be completely solved, and Zhou Yang will not worry about it at all.

After hanging up the phone, Shucheng found Liu Jiangshan and Zhao Huawei, and after explaining the situation, Liu Jiangshan listened to it and called Sunan directly and asked Sunan to send Shucheng back to the project department. After all, Shu Cheng was drinking, and this car couldn't be driven.

Shu Cheng didn't refuse, in fact, Shu Cheng also felt that he was a light bulb here, Zhao Huawei came to join Liu Jiangshan this time, and his sincerity has not yet been expressed, he is here, it seems very inappropriate, after all, he and Liu Jiangshan are not related. Just took advantage of this opportunity to let Liu Jiangshan and Zhao Huawei have an in-depth discussion.

In less than ten minutes, Sunan arrived downstairs at the Xiangshan Club, Shucheng got on the bus, and went to the fourth project department of the third standard of the high-speed railway.

In the car, Shu Cheng was thinking about how to solve the matter that Zhang Wei had made.

According to Hao Hongwei's words, Shu Cheng already knew that the length of this pile foundation is 36 meters, and the pile foundation of less than 40 meters does not have an acoustic tube, which is relatively easy to deal with.

There are several reasons why the catheter cannot be pulled out, such as the catheter hanging on the steel cage, resulting in the inability to lift it, which is more common.

In this case, just turn the catheter slightly, or press down on the catheter to separate the catheter from the steel cage, and the catheter can be lifted.

There is also too much concrete pouring, forgetting to lift the conduit, just like Zhang Wei this time, because there is too much concrete inside, the conduit is fixed to death, just like burying a pipe to a depth of about 20 meters, you have such a great ability to lift him up?

This situation is relatively rare, and it is generally a technician or construction team who has not worked on the pile foundation, so this problem exists.

Zhang Wei belongs to the technician who has not done the pile foundation, otherwise, he would not make such a low-level mistake, because the specification requires that the depth of the conduit should not exceed five meters, and the conduit must be lifted and unloaded.

How to deal with these problems has become the key. In general, the hole is re-drilled with a percussion drill and then the concrete is poured.

However, there are special circumstances, such as one or two meters away from the design elevation during the pouring process, in this case, the first way is to wait for the concrete to solidify, dig the pile foundation, and connect the pile foundation, which is also allowed.

The second method is to wait for the concrete to solidify, use the water to impact hard, wash out the mud or something, and then pour concrete on the solidified concrete after repeated scouring, but this situation is easy to produce a hole collapse, so few people use it.

As for the conduit that cannot be pulled out, after cutting it directly, let it be in the pile foundation as a part of the pile foundation, and many pile foundations can be qualified in the pile foundation inspection process.

When Shu Cheng arrived at the construction site, it was already eleven o'clock in the evening, and at this time, because the conduit could not be pulled out, which affected the pouring construction of another pile foundation, he could only drill in and could not pour.

After Sunan sent Shucheng to the construction site, he returned to Taizhou.

"Brother Shu." Hao Hongwei stepped forward to greet Shu Cheng.

"Mr. Shu!" Zhang Wei also stepped forward and saw Shu Cheng, obviously a little afraid.

"Come with me and see how it goes." Shu Cheng didn't look at Zhang Wei and said directly.

Before coming to the pile foundation, the top concrete bucket has been unloaded, and the concrete inside has been cleaned and worked, otherwise, this bucket would not have been unloaded

Shu Cheng looked at the elevation of the pile foundation with the measuring rope again, and after the inspection, Shu Cheng was generally clear about the situation at the scene.

After seeing the scene, Shu Cheng said to Hao Hongwei: "Let the electrician come over tonight and cut the conduit above the ground overnight, don't expose the conduit to the ground, and after cutting, plug the hole with soil." ”

"Blocked? Brother Shu, there are still two meters left, these two meters are not poured? Hao Hongwei looked confused, he didn't know what Shu Cheng meant by doing this.

For cutting the catheter, Hao Hongwei also guessed that now the catheter can't turn, and the ground will be exposed if it is not cut.

As for what Shu Cheng said about plugging this hole, Hao Hongwei didn't understand.

"Yes, after plugging, record this hole, and after getting off work in the afternoon the day after tomorrow at the latest, let the construction team dig out the pile foundation, dig to the concrete position poured today, cut the extra conduit again, and then use an electric drill to chisel the hair, expose the new concrete, and connect the pile!" Shu Cheng arranged.

Because there is only one meter to the top of the pile, it is completely possible to pour one meter and a half, including 50 centimeters of the pile head, for pile connection.

The reason why I chose to work at night is because I am afraid of inspection, this kind of thing, it is best not to be exposed, and in addition to night construction, the on-site supervisor does not go, and it is easy to deal with any problems.

"Docking, that's okay?" Hao Hongwei was a little surprised.

This is the first time he has encountered this kind of thing, and before that, Hao Hongwei had never even heard of it.

"Well, the construction team should have done it, it is best to set up the formwork, tomorrow during the day, you ask the construction team to get a one-meter-five-high, one-meter diameter thing, directly put on it, you can directly pour concrete inside.

Shu Cheng continued to say to Hao Hongwei.

"Okay, I'll find Lao Huang tomorrow and get this done." Hao Hongwei nodded.

If this method is feasible, you can save a lot of money, you must know that the percussion drill is much more expensive than the rotary drilling drill, one meter is not five hundred, people may not do it.

"The quality of chiseling and piling must be well controlled." Shu Cheng mentioned again.

In fact, Shu Cheng has another idea, that is, when the pile is inspected, it is a big deal to give the third-party inspector 5,000 yuan, and this pile will pass like this.

Like some pile foundations with acoustic tubes, during the testing process, the acoustic tubes are likely to be blocked, so there is no way to monitor, and in this case, the third-party inspectors are given 5,000 yuan to solve the problem. (To be continued.) )
