灌注桩与高压旋喷桩形成止水帷幕的施工应用

The construction application of cast-in-place piles and high pressure jet grouting piles to form water-stop curtain

结合具体工程实例,根据钢筋混凝土桩及高压旋喷桩的材料特性,介绍了两者有效结合形成的止水帷幕具有止水和基坑支护的双重作用,并阐述了高压旋喷桩的施工方案确定和施工工艺流程,为类似工程积累了宝贵经验。

According to the material features of reinforced concrete piles and high pressure jet grouting piles, combining with the specific project examples, the thesis introduces the water-stop curtain formed by effective combination of them have not only the function of water stopping but also the function of foundation pit supporting, and illustrates the determination of construction plan for high pressure jet grouting piles and construction technological process, which accumulates the precious experience for the similar projects.
