Fixing sleeve capable of recyclable front support grouting steel pipe
The invention discloses a fixing sleeve of a recyclable front support grouting steel pipe. The fixing sleeve comprises a sleeve body and is characterized in that the fixing sleeve body is a section of steel pipe made of DN400, the length of the steel pipe is determined according to a basement bottom plate or a basement outer wall of an actual project, and the steel pipe is placed on the basement bottom plate or the basement outer wall after a foundation pit is excavated; and the outer side of the front support grouting steel pipe needs to be sleeved with the fixing sleeve, and water stop pieces are welded on the periphery of the fixing sleeve. The fixing sleeve of the recyclable front support grouting steel pipe has the advantages that the fixing sleeve is simple in structure and convenient to manufacture, the construction efficiency of a foundation pit support is improved, the construction safety is effectively guaranteed, the fixing sleeve can be conveniently and flexibly applied to the foundation pit support in a complex environment, the fixing sleeve is convenient to operate and recyclable, and the engineering cost is reduced.
一种可回收前撑注浆钢管的固定套管，包括套管本体，其特征在于：所述固定套管本体为一段材质为DN400钢管，钢管的长度尺寸根据实际工程地下室底板或地下室外墙而定，使钢管在待基坑开挖后放置于地下室底板或地下室外墙处；固定套管需套进前撑注浆钢管的外侧，固定套管四周焊接止水片。本发明的可回收前撑注浆钢管的固定套管具有固定套管结构简单、制作方便，提高基坑围护施工效率，有效保证施工安全，且方便灵活运用到复杂环境下的基坑围护中，固定套管操作方便、可回收和降低工程成本的优点。
