The foundation construction and reinforcement of offshore construction projects such as ports, offshore airports and artificial islands are much more difficult than those on land. It is obviously unreliable to directly construct on the soft seabed composed of silt and organic impurities. In order to effectively solve the problem of construction and maintenance of seabed soft soil foundation, compared with traditional methods, new technologies such as water plastic drainage board and water mixing pile DCM are adopted, which have lower construction cost and less impact on the marine environment and aquaculture. It is an inevitable development trend of seabed soft soil foundation treatment methods.
It integrates many R & D technologies such as environmental protection treatment system and intelligent control construction, grasps the intelligent core construction technology, and breaks the monopoly of foreign countries in this field.
The strong water full hydraulic intelligent PVD hard soil penetration is strong. Compared with the domestic counterparts, the construction is more efficient and breaks the domestic technical barriers. It is widely praised by the industry.
·It has 4 DCM engineering ships ·15 onshore DCM pile machines ·3 PVD engineering ships
The above water DCM construction method integrates a number of high-end technologies such as underwater (underground) soil cutting and mixing, precise injection of cement slurry, high and low slurry nozzle exchange, environmental protection treatment system, and intelligent control construction. It has mastered the core technologies of intelligent construction such as mobile positioning system of engineering ships, leveling system, cement slurry mixing and grouting system, drilling and lifting pile making system, breaking the monopoly of Japan and South Korea in this field, It is a domestic technology pioneer. It has 4 DCM engineering ships and 15 onshore DCM pile machines.view more
The water full hydraulic intelligent PVD construction technology is a patented innovative technology, with strong penetration of hard soil layer and high construction efficiency. 12 30 meter long drainage boards are constructed in one and a half minutes. The domestic counterparts generally use vibrators to construct 2-4 drainage boards at a time, and the construction time is longer. In the "three runs" project of Hong Kong airport, it has been praised by the Hong Kong Airport Authority for many times. It has accumulated 20 million meters of water PVD (plastic) drainage boards, and the equipment operation is very successful, which makes the engineering community refreshing. It has 3 PVD engineering ships.view more
