1 People s Hospital of Wuhu City where service foundation prop technique including drill hole grouting pile, deep mixing pile, water-proofing pole and pressure casting have been taken, which not only ensures the construction quality, but also save the investment and achieve a good effect.

The application of single-row pile combined with water-resisting curtain in deep excavation work;

The application of high-pressure rotating water-resisting curtain under complex sea-frontl geological conditions;

The application of soil nailing and water-resisting curtain in deep foundation pit supporting;

5m, including sloping excavation, mesh and shotcrete on the slope, pressure-spraying mortar into riprap layer to form water-stop curtain and etc.

Single-pipe revolving spray technique was used to treat the foundation of multi-conduits in the construction of water-stop curtain work of the right abutment at Beijing Sanjiadian Reservoir.

Application of waterproof curtain of multi-head & small-diameter deep concrete mixture;

United construction of deep basic pit soil nail and waterproof curtain in high architecture;

The support of grid type cement-soil mixing pile and the technology of waterproof curtain

Finite element analysis of environmental effects of waterproof wall on foundation pit;

Based on Biot s consolidation theory and the finite element analysis program of COFIST,the environmental protection effects of such influencing factors as embedded depth of waterproof wall and foundation properties are discussed in this paper.
