只看楼主 我来说两句 抢板凳污水提升泵站压密注浆施工方案
Execution Plan for Compaction and Grouting
一、 前言Preface
污水提升泵站压密注浆主要针对其基坑底板下部的约1.8m厚的粉土,因其底板呈阶梯部,部份土体滑动,造成部份底板与其下部粉土的分离,而形成空洞,目前通过现场勘察,因破坏处为16×3×1.8m。因而要求采用注浆方式进行土体加固。This plan is mainly aimed at about 1.8m THK powder soil in the bottom slab of foundation pit. As the bottom slab is in a step and part of the soil is slided, some slabs are separated from the powder soil. So the hollows turn up. After the site investigation, as the broken area is 16*3*1.8m, method of grouting should be adopted for the soil strengthening.
