上软下硬地层地下连续墙施工技术

Construction Technology of Diaphragm Wall in Softness over Hardness Formation

钰龙金融广场深基坑工程项目采用地下连续墙支护结构形式,基坑平面形状近似菜刀形。周围环境复杂,受到众多因素的制约,基坑变形控制要求非常严格,施工难度非常大。以此工程地下连续墙项目为实例,介绍超深地下连续墙施工要点,并对施工过程中影响地下连续墙质量的因素进行归纳和总结。

Supporting structure form of diaphragm wall is adopted in deep foundation pit engineering project of Yulong financial Square. Surrounding environment is complex, by many factors, the deformation control of foundation pit is very strict, it also increases the difficulty of construction. Taking diaphragm wall of Yulong Financial Square as an example, the paper introduces construction points of ultra-deep diaphragm wall. The factors that affecting the quality of the diaphragm
