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.Details >
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.Details >

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.Details >
Shanghai MILITARY INDUSTRIAL ROAD CROSS-RIVER TUNNEL IS LOCATED IN Shanghai PUDONG MILITARY INDUSTRIAL ROAD, WHICH IS ONE OF THE TWO IMPORTANT CROSS-RIVER PROJECTS IN THE construction OF THE CENTRAL RING Road. It is an important node connecting Pudong and Puxi in the southeast of the Central Ring Road. < br/> The construction line of the Military-industrial Road tunnel is long, and the main line is divided into 30 construction sections. The inlet and outlet are connected with the entrance of the elevation frame of the Central ring Line A1.1, and the terminal point is connected with the standard of the central ring Line A1.1. The maximum excavation depth is 26.5m.Details >
Focus on the city foundation pit and slope engineering (geological disaster management engineering) hazard source monitoring field, through the open data interface, toBIMFor the project information carrier,GPS/The Beidou position is in harmonyGISAs the information carrier of project group, combining with automatic monitoring and mobile Internet technology, the monitoring data collected automatically on site are integrated and summarized in this system. At the same time, the early warning mechanism of pit and slope safety monitoring is established to give real-time hierarchical alarm.......Details >
Shanghai Vanke Anting New Town Project is located in the east of Anyong Road, Jiading District, Shanghai, south of Anli Road. It is a residential project.
Pile foundation engineering adopts static pressure pipe pile construction; The foundation pit project adopts the combination of slope excavation and gravity cement earth wall enclosure, and partially adopts steel pipe grouting inner cast support and steel cement soil mixing wall(Biaxial stirring pile)Enclosure.

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.
