空间受限情况下地下连续墙施工技术

Construction Technology of Underground Diaphragm Wall Limited by Space

摘要:

地下连续墙施工过程中会受到施工环境的限制，空间受限是其一。基于工程实践，对空间受限情况下地下连续墙施工技术进行研究。根据不同的限制条件，将地下连续墙成槽施工空间受限条件分为三类：低净空限制、导洞内限制以及障碍物限制。对三类受限情况以及对应受限情况下地下连续墙施工技术分别进行阐述，并对低净空以及障碍物限制下地下连续墙施工进行了案例说明。

Abstract:

The construction process of underground diaphragm wall will be restricted by the construction environment, and the space limitation is one. Based on the engineering practices, the construction technology of underground diaphragm wall limited by the space is studied. According to the different constraints, the space constraint conditions of underground diaphragm wall grooving are divided into three categories, i.e. low clearance restrictions, restrictions in the pilot tunnel and the obstacle restrictions. The three types of restricted conditions and the corresponding construction techniques of underground diaphragm walls under the restricted conditions are described, and the construction of underground diaphragm wall under low clearance and obstacle limitation is illustrated.
