Static pile technology

Static pile pressing is a method of pile foundation construction in engineering. The static pile pressing method is a pile driving process in which prefabricated piles are pushed into the soil by the pile pressing mechanism of static pile pressing machine with the counterweight of pile pressing machine and frame. Advantages OF static pile: IT completely avoids vibration, noise and pollution caused by hammer hitting pile, so it has the advantages of no damage to pile, no noise, no vibration, no impact force and no pollution during construction.

Stiffened pile technology

SMWissoil mixing wall The construction method is also known as the steel cement soil mixing wall. It is used to drill and dig into a certain depth soil layer in the engineering site with a multi-axis type drilling mixer, and at the same time, the cement slurry is spouted out at the drill bit and the foundation soil is repeatedly stirred, forming a continuous and complete underground wall with a certain strength and stiffness.
Stiffened pile technology through special machines and tools, using high-pressure rotary jet grouting and mixing combination process, in the soft soil layer (silt soil and silt soil under high water level) formed in the vertical or inclined large diameter cement soil pile body, at the same time, the anchor reinforcement and anchorage, and can apply prestressed retaining pile or pull-out pile.

Technology of displacement foundation treatment of fluidized solidified soil

Intelligent piling integrated equipment

The flow-solidified soil displacement foundation treatment technology has high strength and fluidity suitable for pumping construction, not only the construction speed is fast, but also the ready-mixed flow-solidified soil formed has high strength, controllable quality, low cost and suitable With a wide range of environmental friendly, is a very good construction material.
Smart plant using special mixing grouting pile 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 side of the pile and the end of the soil-cement solidified, and the pile formed a body.
