After Luo Fei, Dong Lei and Shi Qiang arrived at the scene, after preliminary analysis, it was caused by the fact that the safety factor of pipe surge resistance could not meet the stability of pipe surge resistance, and Luo Fei didn't know much about this, but when Shi Qiang patted his chest and said that he could remedy it, he agreed to their plan and quickly organized workers to remedy it.
First of all, the water inrush point is covered with a crude steel pipe, and then the water is drawn out, and the steel pipe is filled with coarse sand and gravel with good gradation, and these filter materials are used to prevent a large amount of sand loss.
The next step was to suspend the excavation of the foundation pit of the pump room, check and strengthen the supporting structure, and pour the concrete of the outer floor structure of the external pump room.
However, what makes Luo Fei most depressed is that there is only one concrete batching plant in the whole Changxing Island, and the result can be imagined, the price of concrete is twice as high as that of Pudong, and the price of C30P6 impermeable concrete is 600 yuan per party.
Luo Fei also knows that if the Jiangnan Changxing Shipbuilding Base project starts, it will definitely build a large-scale concrete mixing plant to supply concrete for the construction of the base, after all, such a large shipbuilding base needs at least more than 3 million cubic meters of concrete.
It's depressing enough to think about it, Luo Fei secretly decided that when the time comes, he will simply take down the concrete batching plant project and open a concrete batching plant in the base, which can be regarded as a contribution to the construction of the base, so that the conditions proposed by Gao Mingyue will be met, and of course, the foundation project will also have to be tendered.
This good remedy is more effective, this time the pipe gushing is blocked, the cost is not too high, did not cause greater losses, after all, if the foundation pit collapses, not only to re-enclose the excavation, this will seriously delay the construction period, then the compensation will be terrible!
This time it was unfavorable, fortunately, there was no danger, but this also reminded Luo Fei that doing this kind of water-based foundation project is not like an ordinary foundation project, and it must be done well when making the construction plan, otherwise there will be a big problem, or even a safety accident with major casualties, and even he, a small boss, will have to go in!
…… China Shipping Third Harbor Linhai Concrete Co., Ltd. recently received an order for PHC pipe piles, and Yuehai Shipping Engineering Co., Ltd., located on Changxing Island, wants to purchase a batch of PHC pipe piles for the construction of a new ship repair dock infrastructure.
For this order, the company's leaders also attach great importance to it, led by the company's general manager Fan Dalin personally, chief engineer Duan Yongfu participated, and the sales department, technical quality department and production department each sent a representative of the team to Changxing Island Yuehai Shipping Engineering Co., Ltd. for business negotiations and technical disclosure.
Li Fusheng was also fortunate to participate in this mission, and now he is also the technical backbone of the company, Duan Yongfu, the chief engineer, personally named him and asked him to go together, which made him feel very proud.
This was the first time Li Fusheng had sat on a "big boat", and the two Santana sedans of their company got on the ferry, and the group also went to the upper cabin of the ferry.
Although this car ferry is not actually a large ship, its displacement is only a few hundred tons, the lower deck can carry 30 standard cars of 5 tons, and the upper deck can carry 150 passengers.
However, in the eyes of Li Fusheng, a migrant worker from the mainland, it is already a big ship, of course, it cannot be compared with those 10,000-ton giant ships on the Pujiang River, even with those Type 022 missile boats clad in marine camouflage on the military docks.
Li Fusheng is a military fan, so when he saw the three Type 022 missile boats moored on the dock, he couldn't help but run to the deck and stare at the three strange-shaped catamaran missile boats.
This is the Type 022 stealth missile boat that is rumored on the Internet?
Li Fusheng was excited.
I didn't expect it to come out this time, and there are such benefits.
The appearance of those missile boats is too sci-fi, it looks as if it does not belong to the earth, and he also heard that these missile boats were built by Shen Huan, and now they are also like dumplings, which were built and rolled off the assembly line in Jiangnan Changxing Shipbuilding Group, and then served in the three major fleets.
These should be the latest batch of missile boats received by the missile boat group of the East China Sea Fleet!
Li Fusheng looked at his saliva and drooled, it would be good if he could get on the boat to visit, of course he knew that it was impossible, because this kind of missile boat is China's most advanced missile boat, and it is also very leading in the world, and it is impossible to open it for viewing now, after all, the secrecy system is still very strict.
At this time, Duan Yongfu also walked to Li Fusheng's side, looked at him with a smile and said, "Xiao Li, do you like these warships?"
” Li Fusheng hurriedly nodded and said, "Ah, Chief Engineer Duan, are you also a military fan?"
” Duan Yongfu smiled: "I can't be regarded as a military fan, but I still like to see our country's warships, these warships are very special, they seem to be new ships, have you heard of them?"
” Li Fusheng said with a smile: "I have read it on the Internet, and I have a friend who works in Jiangnan Changxing Shipbuilding Group, his name is Shen Huan, who is responsible for presiding over the construction of these missile boats, I really envy him, he is only twenty-six or seventeen years old, and he is already the assistant to the president of Jiangnan Changxing Research Institute under Jiangnan Changxing Shipbuilding Group!"
” Duan Yongfu smiled and said: "Xiao Li, don't be discouraged, as long as you work hard, you will also have a chance, three hundred and sixty lines, and you will be the champion."
Although the concrete industry we are engaged in is not as high-end as shipbuilding, some things also have technical content, for example, this time we want to receive orders, the construction of this batch of PHC pipe piles, is the general construction team can not do, so in the technical disclosure meeting, to fully discuss the technical requirements, this time to call you, but also to let you learn well, in the future you can stand alone. ” Li Fusheng said gratefully: "Thank you, Chief Engineer Duan, I will study carefully."
By the way, what is the difference between the construction of a dock floor foundation like this and the construction of an ordinary house building foundation?
” Duan Yongfu smiled and said: "The difference is big, the dock is a hydraulic building, so it must be done according to the standard of hydraulic engineering, and the standard used in ordinary housing construction is different, it is a general construction industry standard."
Take the dock floor foundation as an example, in our Zhonghai shipyard floor is generally built on the soft soil foundation, so under the large-area unloading conditions of the soft soil foundation and the action of periodic heavy load, the pile foundation design of the dock floor is also different.
The cost of the entire floor pile foundation accounts for a considerable proportion of the dock project.
Compared with the pile foundation raft structure of general house construction, the dock floor on the soft soil foundation has several typical characteristics, one is that it is side-limited, and the dock floor is generally surrounded by sheet pile dock walls, the second is that the bottom plate is unloaded in a large area, and the third is that the load on the dock floor is the heavy load of periodic action, and the empty weight of a 100,000-ton ship is generally more than 15,000 tons......"
