Great Power Project

Chapter 687
Because Bailonggang is on the seashore, the groundwater level is relatively shallow, and it has to withstand seawater infiltration from the sea. Therefore, according to the design plan, two seepage interception walls were built around the Bailonggang underground sewage treatment plant to intercept the infiltration from seawater.

Speaking of the seepage wall, Yu Qingyang thought of the seepage wall project that was rejected by his uncle.

Now no one would push him away anymore, this time he not only did it, but Party A and Party B did it together.

The excavation depth of the underground sewage treatment plant is more than 30 meters, and the excavation area is so large, the foundation pit support is also the top priority.

The two outer seepage cut-off walls themselves have the function of supporting and stabilizing, and there is another row of pile walls inside as the support for the side wall of the foundation pit.

It can be said that if the sewage treatment plant is built underground, the main increase is the support costs of the two seepage interception walls and the pile wall.

With the withdrawal of the excavator, the impact reverse circulation drilling rigs of each bid section came on the scene one after another, and the construction of the seepage interception wall began.

Because the excavation depth of the foundation pit exceeds 30 meters, and the depth of the cut-off wall reaches 45 meters. In addition, there is a rock structure underground. The hydraulic grab groover commonly used in the construction of the cut-off wall cannot be used, and only the impact reverse circulation drilling rig can be used.

"The construction of the seepage interception wall is very difficult. It is located on the coastline, and the geological structure is complex..." The chief engineer of Huayu Water in Modu was introducing him to the construction situation on site, but Yu Qingyang was a little distracted.

"However, the biggest difficulty of the whole project is the drainage. If the seepage wall is not well done, the subsequent work will not be able to be carried out at all..."

The chief engineer of Shanghai Huayu Water Affairs graduated from Tongji University as a Ph. Chief Engineer of Hua Yu Water.

The price is a 140-square-meter house in Shanghai, helping him and his wife to settle their household registration in Shanghai and his wife's job.

At present, the price comparison is still acceptable, and the doctor's technical level of Tongji University is still acceptable, except for some rigidity.

However, it doesn't matter. Yu Qingyang doesn't care about this. In his opinion, if there are only good technical people, then it's not serious to engage in technology.

"In order to save the construction period, our plan is to construct the two seepage walls and pile walls at the same time!"

"Two seepage cutoff walls and row pile walls are being constructed at the same time. Will there be mutual disturbance between them? How to solve this problem?"

"When we talk about simultaneous construction, we don't mean simultaneous construction on the same site!
The area we want to finish is more than 120 million square meters. With such a large site, we have enough space for simultaneous construction without mutual disturbance and interference with construction! "

"Hehe! I overlooked this! Well, your idea is good. Simultaneous construction and construction at the wrong time can greatly save time and speed up the construction progress!" Yu Qingyang nodded with a smile.

"Is it just these slotting machines?" Yu Qingyang asked, pointing to the impact reverse circulation drilling machine being assembled in the distance.

"Twelve units have entered the site so far, and more than 20 units will enter the site one after another!" The project manager of Huayu Water in Shanghai hurriedly stepped forward to answer.

"Six tenders, two cut-off walls, about ten kilometers in total, and thirty drilling rigs, can the construction progress be guaranteed?" Yu Qingyang questioned.

Although Yu Qingyang has never done the project of using the impact reverse circulation drilling rig to make the underground diaphragm wall, Yu Qingyang has done the project of using the impact reverse circulation drilling rig to make the cast-in-place pile. It took a month to complete a bored pile with a hole depth of 100 meters.

The principle of cast-in-situ piles is similar to that of diaphragm walls, and the speed will not be much faster. How long will it take for a ten-kilometer underground diaphragm wall at such a speed?

"This is already the maximum capacity of the six construction units!"

"Bullshit! I don't listen to the greatest ability! No diamonds, don't do porcelain work!
Six tenders, each with no less than [-] drilling rigs, if you can’t do it, you will leave!
Also, you are the project manager of Party A, so please correct your position!
He hasn't said he can't do it, why don't you explain it to them first?Whose money do you take? "When Yu Qingyang heard the project manager say the maximum ability, he suddenly became angry and opened his mouth to curse.

"I……"

"You what? Whether you can do it or not is not your consideration. You just need to make requests according to the construction schedule, and let them figure out other things by themselves!" Yu Qingyang reprimanded the project manager unceremoniously.

"understood!"

Rebuking the project manager, Yu Qingyang stared at the six construction units who came to participate in the opening ceremony and asked: "The general managers of your six construction units are all present. The key point of the Bailonggang underground sewage treatment plant is seepage interception. The construction of the wall and the construction of the cut-off wall cannot be completed, and no other work can be done!

You have heard what I just said, so let me just ask, is it possible to transfer [-] drilling rigs within a week? "

"Dong Yu, it is difficult to transfer [-] drilling rigs a week, but we overcome all difficulties and guarantee to transfer the machines!" the boss of Tongnan Construction Engineering promised.

"That's right! Director Yu, we have tried everything possible to transfer the equipment here! Make sure that the construction period will not be affected!" The boss of Sujiang Construction also followed suit.

"There is no problem on our side!" Both local companies said that there was no problem, and China Construction Eighth Engineering Bureau could only follow suit.

The remaining three construction units are Huayu's own enterprises, so it goes without saying that even if they buy new ones, they have to complete the tasks assigned by Yu Qingyang.

"Hehe! Then I would like to thank the bosses first! Thank you for your support to our work!" Yu Qingyang smiled and cupped his hands.

After thanking him, Yu Qingyang smiled and extended the invitation again, "Okay, the leader is gone, and our groundbreaking ceremony is over. I will treat guests at noon, and invite everyone to drink the groundbreaking wine!"

Yu Qingyang, as the boss of Party A, issued an invitation, and these construction units naturally did not dare to refuse.

"Yu Dong, how can I let you treat me, let me treat you!" The boss of Tongnan Construction Engineering laughed.

"This is on our site, I'll invite it, and Mr. Lu will invite it next time!" The boss of Sunan Construction rushed to express that he wanted to treat him.

Yu Qingyang smiled and interrupted the boss of China Construction Eighth Bureau who was about to speak, "Okay, you all don't make any money, this is the start-of-work wine, I invite you as Party A!
Let you treat me next time! "

"Well, okay! Then next time I'll be the host, treat Director Yu to dinner!"

"There will be a chance! This time you have done a good job, and next time we will have many opportunities to cooperate!
Next year, we will build four large solid waste treatment plants in Shanghai!

The scale of investment is not inferior to Bailonggang underground sewage treatment plant!
In addition, after the Bailonggang underground sewage treatment plant is completed, we will invest in the construction of sewage treatment plants nationwide!
The long-term goal of our Huayu Water is to achieve a daily processing capacity of [-] million tons in the next ten years! "Yu Qingyang drew a cake for them casually.
