水泥搅拌桩、高压旋喷桩在嵩厦送电线路的排管和工井施工应用

Application of Cement Mixing Pile and High Pressure Spiral_sprayed Pile in Pipe and Well Construction of Cable's Civil Engineering of SongXia Transmission Line Project

水泥搅拌桩、高压旋喷桩在深基坑围护工程应用,帷幕止水防渗,提供隔水干施工条件,地质情况复杂,遇到地质夹层碎石或块石,部分无法用水泥搅拌桩施工,改用高压旋喷桩,其结果既经济又达到止水效果。

Application of cement mixing pile and high pressure spiral -sprayed pile in deep foundation pit support engineering, not only form waterproof curtain that prevent infiltration, but also offer dry condition for construction . When meeting complex geology of gravel or nubby stone,part of project cant apply cement mixing pile,alternating to high pressure spiral -sprayed pile proofed as an economical and water - repellent solution.
