Drainaging Technology for Construction Subgrade in the Shallow Groundwater Area

Abstract:

In order to solve subgrade problems during the road construction in the shallow ground water area, light well point drainage technology is used, combined with the zhengbian logistics road. This paper expounds application principle of the light well point drainage, calculation and construction methods. When using light well point drainage, the appropriate permeability coefficient is 4 m/d relatively. If using water rushed law construction, water pressure should be controlled in 0.3-0.7 MPa. After well point equipment operates for 3-5 days, the foundation will form the precipitation funnel; then, soil can be excavated after drainaging 7-8d. It is shown that the light well point drainaging can reduce underground water lefficiently.
