To celebrate the opening of the third runway of the Hong Kong International Airport, built on a strong foundation

Hong Kong airport is the biggest challenges facing the third runway construction aspect, before the project starts, sea DCM (mixing pile), land DCM (mixing pile), PVD (drain) in the sea, land gravel pile foundation treatment technology such as are for Japan, South Korea, the monopoly of international advanced technology, before and after the tender, the foreign counterparts enterprises of our country executes strict technology blockade. For this reason, the strong foundation has carried on the thorough research. After more than two years of continuous fighting day and night, countless scientific research, testing and adjustment, we have overcome the difficulties of equipment manufacturing and construction technology of PVD (drainage board) engineering ship, DCM (mixing pile) engineering ship, onshore gravel pile machine, and onshore DCM pile machine, and successfully mastered the core technology.

Large diameter vibrating immersed tube gravel pile technology

Large-diameter vibrating immersed tube crushed stone pile is a deep and large-diameter dense pile body composed of crushed stone formed by sinking the steel feed pipe into the design depth by using high-power vibrating hammer as the driving force, filling the gravel into the hopper and silo, and then pulling out the feed pipe through vibration. Compared with the traditional technology of gravel pile, Shanghai Qiangqiang has mature construction technology and experience, and has dozens of gravel pile construction equipment, which has been successfully used in many large-scale foundation treatment projects at home and abroad.

Strong explanation of water PVD (plastic drainage board) technology

The PVD (plastic drainage board) technology developed by Qiangqiang Foundation Company has strong penetration of hard soil layer and high efficiency in construction. It can construct 12 30-meter-long drainage boards in one and a half minutes, while domestic peers generally use vibrators to construct 2-4 boards at a time, and the construction time is longer.

Strong foundation for you to explain the advantages of intelligent piling construction technology

Using special mixing grouting rig drilling and digging on the design of pile location, at the same time bit in direct injection or rotary jet cement slurry curing agent (and spray into the compressed air when necessary) and the foundation soil by mixing, the formation of columnar cement soil, instant will be prefabricated pipe pile core material depend on gravity and auxiliary equipment such as inserted in the soil, the pile lateral and end cement-soil after curing, It is integrated with the pile. According to the soil layer, the cement injection amount and the diameter of cement soil can be increased at the tip of the pile or the soft soil layer to improve the pile bearing capacity.

The technology of undisturbed earth filling pile

Undisturbed soil-taking cast-in-place pile can be divided into full support cylinder cast-in-place pile and pressure cast-in-place pile. Undisturbed soil full protecting tube piles the craft adopts full steel liners built-in spiral blade cutting soil formation under the double power drill of pile diameter, remove soil liners in the original state at the same time, reinforcing cage under water or inserting reinforcing cage after pouring concrete, reinforced concrete pile is formed after pull out steel liners, especially suitable for greater influence on the compaction of soil. The technology of undisturbed earth - taking and press-poured concrete pile inherits the advantages of long auger - hole press-poured pile.
