: 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.

: Steel support technology for prestressed fish-belly foundation pit

Of steel structure of foundation pit support technology of prestress the stomach, is based on the principle of prestressed, in view of the traditional concrete support, steel support of foundation pit deformation control ability, through a large number of engineering research and application practice, developed a kind of deep foundation pit support structure within the system, it is composed of the stomach beam bent (high strength low relaxation of steel strand as a member) , to brace, Angle brace, column, beam, contact bar, high strength contact, prestressed loading device and other standard components, forming a plane prestressed support system and three-dimensional support structure system.

: The overwater DCM project of Hengqin Mango tunnel project in Shanghai was successfully completed

Recently, the Shanghai strong foundation engineering co., LTD. (hereinafter referred to as "strong" Shanghai) hengqin Mang chau tunnel water period of soft foundation reinforcement engineering of the project has been smoothly completed, this is our water DCM (deep mixing cement-soil pile) technology in the mainland's first successful application, the foundation for our water treatment engineering construction has accumulated valuable experience.
