一种可回收的组合土钉墙基坑围护方法技术

本发明专利技术涉及土木工程领域中的一种可回收的组合土钉墙基坑围护方法，其步骤如下：在开挖面底部施工隔水帷幕（１），然后放坡开挖基坑并施工可拆卸的土钉（２）及与其牢固连接的土钉墙面层（３），完成组合土钉墙基坑围护施工，待基础底板（４）施工完成并养护后，直接将可拆卸的土钉（２）从土体中回收，可消除可拆卸的土钉（２）对周围地区的污染，环保性能好，节约资源，同时通过基坑放坡开挖，可大幅度节约隔水帷幕（１）与可拆卸的土钉（２）的用量，并为可拆卸的土钉（２）的拆卸施工提供了空间，同时缩短了工期，使得基坑围护工程成本大大降低。

Recyclable composite soil nail wall foundation pit retaining method

The present invention relates to the field of civil engineering in a Recyclable composite soil nailing wall pit method, the steps are as follows: in the excavation bottom construction of waterproof curtain (1), then the slope excavation and soil nailing detachable construction (2) and its strong soil nailed wall layer connection (3), complete the combination soil nailing wall pit construction, to the base (4) completed the construction and maintenance, direct the removable nail (2) recovered from the soil, which can eliminate the removable nail (2) on the surrounding area pollution, good environmental performance, saving resources, while the foundation pit slope excavation, water the curtain can be greatly saved (1) and removable nail (2) dosage, and removable nail (2) provides the space construction and demolition, shorten the construction period, the foundation pit engineering Ben greatly reduced.
