Chapter 705 Commencement Ceremony vs Painting Cake
Because Bailonggang is right on the seaside, the groundwater level is relatively shallow, and it has to withstand the penetration of seawater from the sea. Therefore, according to the design plan, two interception walls were built around the Bailonggang underground sewage treatment plant to intercept the penetration of seawater.
Speaking of the interception wall, Yu Qingyang thought of the interception wall project that his uncle pushed down.
Now no one can push him away anymore. This time he not only does it, but Party A and Party B do it together.
The excavation depth of the underground sewage treatment plant exceeds thirty meters, and the excavation area is so large, foundation pit support is also a top priority.
The two outer seepage walls themselves have the function of supporting and stabilizing, and there is also a pile wall inside as a support for the side walls of the foundation pit.
It can be said that when the sewage treatment plant is built underground, the main increase is the support cost of the two seepage walls and the pile wall.
As the excavator was withdrawn, impact and reverse circulation drilling rigs from each bid section came on stage one after another to start the construction of the seepage wall.
Because the excavation depth of the foundation pit exceeds 30 meters, and the depth of the seepage wall reaches 45 meters, and there are rock structures underground, the hydraulic grab troughing machine commonly used in the construction of the seepage wall cannot be used, and impact reaction can only be used.
Circulation drilling rig.
"The construction of the interception wall is very difficult. It is located on the coastline and the geological structure is complex..." The chief engineer of Modu Huayu Water Affairs was introducing him to the on-site construction situation, but Yu Qingyang was a little distracted.
"However, the biggest difficulty of the entire project is drainage. If the interception wall is not done well, subsequent work will not be carried out at all..."
The chief engineer of Modu Huayu Water Affairs graduated from Tongji University with a doctoral degree. He once worked in a central enterprise. Because of his lack of emotional intelligence, he was not very happy working in a central enterprise. Later, he was poached by An Yuqing with a high salary and served as the director of Modu.
Chief Engineer of Huayu Water Affairs.
The price is a 140-square-meter house in Modu, helping him and his wife settle their household registration in Modu, and getting his wife's job.
At present, it seems that the price-performance ratio is still acceptable, and the technical level of this PhD student from Tongji University is still acceptable, except for being a bit rigid.
However, this doesn't matter. Yu Qingyang doesn't care about this. In his opinion, if you are a technical person, you are not a serious technical person. If you are not qualified, you will not be able to do technology well.
"In order to save construction time, our plan is to construct two seepage intercepting walls and pile row walls at the same time!"
"If two seepage interception walls and pile walls are constructed at the same time, there will be mutual interference between them, right? How to solve this problem?"
“When we talk about simultaneous construction, we don’t mean simultaneous construction at the same location!
The area we want to complete exceeds 1.2 million square meters. For such a large site, we have enough space to carry out construction at the same time without disturbing each other or interfering with the construction!"
"Haha! I ignored this! Well, your idea is good. Construction at the same time and at the wrong time can greatly save time and speed up the construction progress!" Yu Qingyang nodded with a smile.
"Are these the groove forming machines?" Yu Qingyang asked, pointing to the impact and reverse circulation drilling rig being assembled in the distance.
"Twelve units have already entered the site so far, and more than 20 units will arrive later!" The project manager of Modu Huayu Water Affairs hurriedly stepped forward to answer.
"Six tender sections, two intercepting walls, a total of almost ten kilometers, and thirty drilling rigs can guarantee the construction progress?" Yu Qingyang questioned.
Although Yu Qingyang has never done the project of using an impact reverse circulation drilling rig to build underground diaphragm walls, he has done it before using an impact reverse circulation drilling rig to make cast-in-place piles. A cast-in-place pile with a hole one hundred meters deep took a month to complete.
.
The principles of cast-in-place piles and diaphragm walls are similar, and the speed is not much faster. At such a speed, how long does it take to build a ten-kilometer underground diaphragm wall?
"This is already the maximum capacity of the six construction units!"
"Bullshit! I don't listen to what your maximum ability is! If you don't have a diamond, don't get the porcelain job!"
Each of the six bidding sections has no less than 30 drilling rigs. If you can't do it, you'll have to leave!
Also, you are the project manager of Party A, so position yourself accordingly!
He hasn't said it can't be done yet, why don't you explain it to them first? Whose money are you taking?" When Yu Qingyang heard the project manager talk about his maximum capability, he immediately got angry and opened his mouth to curse.
"I……"
"What are you doing? Whether you can do it or not is not your concern. You only need to make requests based on the construction schedule and let them figure out other things on their own!" Yu Qingyang scolded the project manager unceremoniously.
"knew!"
Reprimanding the project manager, Yu Qingyang stared at the heads of 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 to intercept seepage.
If the wall construction and seepage interception wall construction are not completed, you cannot do any other work!
You have all heard what I just said, so I would like to ask, can it be done by deploying thirty drilling rigs within a week?"
"Director Yu, it is difficult to mobilize thirty drilling rigs a week, but we will overcome all difficulties and ensure that the machinery will be transferred over!" the boss of Tongnan Construction assured.
"Yes! Director Yu, we will try our best to transfer the equipment! We guarantee that the construction schedule will not be affected!" The boss of Sujiang Construction Engineering also expressed his position.
"We have no problem here!" Two local companies said there was no problem, and China Construction Eighth Engineering Bureau could only follow suit.
The remaining three construction companies are Hua Yu's own companies. It goes without saying that even if they buy new ones, they still have to complete the tasks assigned by Yu Qingyang.
"Haha! Then I would like to thank the bosses first! Thank you for your support of our work!" Yu Qingyang said with a smile and cupped his hands.
After saying thanks, Yu Qingyang smiled and extended the invitation, "Okay, the leader has left, and our opening ceremony is over. I'll treat you to the opening wine at noon!"
As the boss of Party A, Yu Qingyang issued an invitation, so these construction units naturally did not dare to refuse.
"Director Yu, how can I treat you to a treat? Let me treat you!" the boss of Tongnan Construction Engineering said with a smile.
"This is on our territory, so let me treat you. Mr. Lu will invite you next time!" the CEO of Sunan Construction Engineering said eagerly that he wanted to treat him.
Yu Qingyang smiled and interrupted the CEO of China Construction Eighth Bureau who was about to speak, "Okay, you all don't want to earn any money. This is the opening drink. As Party A, I treat you!"
I’ll let you treat me next time!”
"Okay! Then next time I'm a host, I'll treat Director Yu to dinner!"
"There will be a chance! If you do a good job this time, we will have many opportunities to cooperate next time!
Next year, we will build four large-scale solid waste treatment plants in Shanghai!
The investment scale is no less than that of Bailonggang underground sewage treatment plant!
In addition, after the Bailonggang underground sewage treatment plant is completed, we will invest in building sewage treatment plants nationwide!
Our long-term goal of Huayu Water is to reach a daily processing capacity of 100 million tons in the next ten years!" Yu Qingyang drew a piece of pie for them.
