Lin Wei's arrival did not cause any waves on the entire construction site, not only Li Huayong didn't care, but Lei Jianjun also didn't pay much attention to it.

In a way, the construction industry is very similar to the military, which is basically a man's world. There used to be a saying, "War makes women go away." In fact, construction sites also make women walk away.

Of course, there are women in the construction industry, but women are generally engaged in accounting, budget and final accounts, logistics, office, data management, and so on. And those who need to rush to the front line, such as safety, quality, on-site construction management, production arrangement, etc., are almost invisible to women.

Of course, it can't be said that there is no one at all, but women who can rush to the front line on construction sites often have the attribute of "female men". is just Lin Wei's delicate beauty, how do you look like a "female man". With her as the director of the whole project, how to think about it is funny. Therefore, when she came to the construction site, not many people cared about the fact that Party A had such a person.

Of course, the reason why everyone doesn't care about having an extra director out of thin air is also related to the current situation on the construction site, when Lin Wei came to the construction site, the whole project was at a very critical time.

At present, the construction of manual digging piles has been carried out for more than 10 days, according to the speed of one meter a day, that is, from this time, the manual digging stage of part of the pile foundation has been completed, and it will be delivered to the drilling rig to continue the operation.

The entire site will enter a mixed phase of manual and mechanical drilling.

This is a very critical stage, and the on-site management of this stage is very difficult.

If you ask an expert with experience in pile foundation construction, what is the biggest feature of pile foundation construction? Then this expert will tell you: can not be stopped! Must ensure continuous operation is the biggest feature of pile foundation construction.

When a pile foundation is drilled to reach the design elevation, you can't stop at this time, you have to get off the reinforcement cage immediately, you have to pour concrete immediately. You can imagine a pit that is more than 20 meters deep, and it is a vertical pit with a hole diameter of just over 1 meter, and if you dare to leave it for too long, it can collapse at any time. Once the collapse you will be in trouble, not to mention the rest, in order to ensure the quality of the pile foundation, you must at least clear the floating soil of the collapse from the hole pile, right?

It's a cumbersome process, and it's also quite a headache. Because once this kind of thing happens, the first one is to waste materials and increase construction costs, because the hole size is expanded due to landslides, and it has become inevitable to pour more concrete.

In his previous life, Li Huayong had encountered this kind of thing, a pile foundation with a design volume of only 20 square meters, because of the collapse, because of repeated hole cleaning, it is very common to pour more than 40 square meters in the end.

One side of the concrete is hundreds of pieces large, take this project as an example, there are more than 800 pile foundations in total, if there is a collapse problem everywhere, each pile is poured a few more squares or more than a dozen square concrete, then you still do a fart project, a project will not kill you.

There is no other way to solve this problem, the only effective way is to be "fast"! You have to drill fast, the faster the speed, the less likely it is to cause collapse, after the hole pile is formed, you have to pour the concrete quickly, you have to come out of a pile and pour the concrete immediately.

This is the biggest feature of pile foundation construction. What is called day and night? When the pile foundation is constructed, it is really called day and night. Some time ago, when only manual digging piles were done, there was no night construction. Even if the workers wanted to work more, for safety reasons, the project department and Li Huayong would not agree to their night work. But once you get to the mechanical drilling stage, night construction is imperative.

Pile foundation construction is not only this problem, the above is the biggest feature of pile foundation construction, if you also ask an expert with experience in pile foundation construction: pile foundation construction is the most important, what is the most critical problem? Then this expert is likely to tell you: the key to pile foundation construction is mud! "Slurry" problem may be the most important problem of pile foundation construction.

Many people who have seen the pile foundation construction site may have the impression that as long as you enter the pile foundation construction site, you will feel particularly dirty, and you can see mud pools and mud water everywhere. So what is the function of these muds?

In the stage of manually digging piles, the method of manually pouring concrete can be used to protect the wall. But once the drilling rig is erected, you can no longer carry out artificial wall protection, mechanical drilling must also do a good job of wall protection, what to use to assume the role of wall protection?

Slurry!

How important is the mud retaining? You can give an example from real history to illustrate this problem.

In Fujian Province of our country, when a bridge was built on the Minjiang River in the early years, the bridge also had a pile foundation, but the pile foundation requirements for carrying the bridge were much higher, and the design pile length of many pile foundations of this bridge was more than 40 meters deep.

In order to lay these piles, the construction unit at that time deliberately pulled several truckloads of mud from Shandong to Fujian.

What kind of soil is pulled? The scientific name of this soil is "bentonite".

Of course, compared to this scientific name, another name for this soil is very famous: Guanyin soil.

As for why this soil is pulled, many people should be able to understand it by now, right?

Of course, the purpose of using this soil is to make mud.

Of course, it cannot be said that there is no clay in Fujian, but the construction unit at that time was always not satisfied with the local materials, and the design requirements could not be met, and the phenomenon of landslides often occurred. Later, after many interrogations, I thought of going to Shandong to get soil when I had no choice. Not to mention, the mud made of "Guanyin soil" is really good, and the pile foundation of the bridge can be successfully completed.

I don't want to explain anything else with this example, but I want to illustrate the importance of mud for pile foundation construction. It is no exaggeration to say that the problem of pulping is the key to pile foundation construction. It may be difficult for outsiders to understand this, but many insiders must have a deep understanding of it.

Of course, this project does not need to go to Shandong to pull any "Guanyin soil", first, Pengcheng itself has clay, and secondly, the pile foundation of more than 20 meters is not long, and the requirements are not so high, and the local soil pulp can also meet the requirements.

However, because there is now night work and mixed construction, there are still so many mud pools and mud water in the whole construction site. After entering this construction stage, from Lei Jianjun to Li Huayong, they began to be busy one by one, and for more than a week, everyone was in a state of continuous rotation.

Nearly half of the more than 100 workers under Li Huayong's hands came from the drilling rig team, and now that the drilling rig team has begun to resume construction, Li Huayong must return some of the workers to others, right? Moreover, this part of the workers is not a one-time dismissal, and it needs to be returned gradually and gradually, so how to rationally arrange the labor force and ensure that things on both sides will not be delayed, this is a matter that Li Huayong needs to balance.

In addition, because mechanical drilling has begun, after penetrating the "boulder layer", the efficiency of mechanical drilling is still very high, about 15 meters, a drilling rig to complete 2 a day may be a bit reluctant, to complete one is definitely more than enough. Therefore, another "business" in Li Huayong's hands, arranging workers to "put cement" in the mixing plant has begun, which also requires Li Huayong to arrange manpower.

Not only these, but because night construction is now required, you can imagine that hundreds of holes have been dug up in the whole site, and some of the holes have been as deep as several meters or ten meters, so it is actually a very dangerous thing to carry out night construction at this kind of construction site, what if someone falls into the hole at night? Therefore, how to do a good job of safety precautions, how to take some safety measures, this is also something that Li Huayong needs to consider.

All of this has kept Li Huayong very busy, and he has not slept well for more than a week.

The time came to the end of July 1984, and Li Huayong had been crossing for nearly a month, and he had been working at the Shekou construction site for nearly half a month.

On this day, Li Huayong was taking a nap, which was a rare time for him to find this moment to rest for more than a week.

"Dun dun, get up... ”

Li Huayong, who was woken up by his cousin's "pillar", began to get angry:

"If there's nothing particularly important, look at how I'll clean you up. ”

Li Huazhu didn't care about his cousin's intimidation:

"Quick, go, Manager Lei and Minister Xia Gong Deng are looking for you, and they are on the scene. ”

"Oh? Do you know what's going on?"

"I don't know, I saw a lot of people standing on the scene, not only Manager Lei, but also those Xiangjiang people from Party A, among whom there is a very beautiful woman... ”

"I'm asking you what you're looking for me, not what you're looking for. ”

"I really don't know, it was Chief Engineer Xia who notified me to call you. It's just that I heard Minister Deng say that those Xiangjiang people... It's like finding fault. ”

"Oh, find fault?"
