挡土墙单侧支模施工技术

Construction technology of retaining wall single side formwork

随着城市的发展和施工中节地的要求,为了实现土地的充分利用,开发尽可能多的建筑空间,出现了许多拟建建筑地下室外墙紧贴基坑支护的设计,造成地下室外墙外侧无施工空间,单侧支模的施工技术应运而生。针对基坑项目施工场地狭小,只能采用单侧支模体系的问题,本文采用槽钢斜撑单侧支模体系的施工方法,既能够满足施工需要,又降低了施工技术难度,实用性及经济性效果显著。

With the development of the city and the requirement of land conservation in construction,in order to make full use of the land and develop as much building space as possible,there are many designs of the proposed building basement exterior wall close to the supporting pile,which results in no construction space outside the basement exterior wall.The construction technology of single side formwork came into being.In view of the narrow construction site of the foundation pit project and the problem that only one side formwork support system can be used,this paper adopts the construction method of single side formwork support system of channel steel diagonal bracing,which can not only meet the construction needs,but also reduce the construction cost and technical difficulty,and has significant practical and economic effects.
