Multi - axis continuous wall drilling machine is a special machine developed for cement - soil mixing pile construction. The equipment uses multi-axis blade drilling tool to drill in the soil to the design depth, while lifting the drill from the end of the bit injected suitable for different processes of cement slurry, slurry and unchanged soil mixing, in the original position to build a section of cement wall; Then the second section of wall construction, so that the adjacent cement wall each other have coincidence section, continuous construction can be made into underground continuous wall. According to different needs, it can be inserted into shaped steel for water stop or soil retaining of deep foundation excavation. At present, there are two axes, three axes, four axes, five axes, six axes and other types of cement mixing pile construction technology.
Application: It is widely used in soft soil foundation soil reinforcement, soil reinforcement in soft soil foundation pit, gravity retaining wall structure of soft soil foundation pit support, steel cement soil retaining wall structure and foundation pit water stop curtain.
Technical parameters: single hole pile diameter:Φ650,Φ850, pile depth: maximum up to50m.

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.
Macao New Town Area A B4 foundation pit supporting steel support project The project is located in Section B4, Area A, Macao New Town. The foundation pit circumference is about 410m, the area is about 10,698 square meters, and the maximum excavation depth is 15.45m. The foundation pit supporting technology of prestressed fish-belly type foundation pit steel support (referred to as "fish-belly beam construction method") + steel sheet pile is adopted, which was started on March 10, 2021.
Foreign projects, high-energy dynamic consolidation: Colombo Port City Colombo Port City Development Project is located in the south of the south near the South Port of Colombo, capital of Sri Lanka. It is bounded by the South Port breakwater to the north, the Galle Valley to the south, and the coastline to the east. < br/> On March 29, 2018, the project was named by Forbes magazine as one of the "Five New Cities that will influence the future".
