Foundation pit underground water control form of foundation pit supporting construction unit

In the construction process of foundation pit supporting engineering, the construction unit of foundation pit supporting engineering should consider the treatment of groundwater at the same time, that is, how to control groundwater, which is an important content in the design and construction of foundation pit engineering. Especially in sandy soil and silt soil, when the water is shallow and abundant, sometimes there is confined water layer in the lower aquifer, it becomes an important factor affecting the stability of foundation pit.

Floating DCM (stirring pile) engineering ship, what is the floating DCM (stirring pile) technology.

Water DCM (mixing pile) engineering ship can work in the coastal sea, offshore sea towage dispatch, suitable for coastal port wharf, breakwater, revetment, artificial island land reclamation foundation treatment construction. The construction principle is as follows: cement or cement-solidified material is added to the soft clay according to the relevant ratio, and at the same time, the construction method is forced to mix and mix, and the solid and stable soil is formed in the foundation by chemical curing, so as to achieve the purpose of strengthening the underwater soft soil as the foundation of hydraulic construction.
