预制装配式柱板组合挡墙施工工法

Construction Method of Prefabricated Column-slab Composite Retaining Wall

预制装配式柱板组合挡墙施工工艺采用装配式预制板与柱组合结构,同时针对不同的基础结构进行了不同的优化,当基础采用条形浅基础时,可省略传统预制柱施工时的临时支撑步骤,且连接强度高。当采用预制柱时,抗剪锚固筒在桩基施工时植入,并在筒周浇筑扩大段,有效保证连接段的稳定性。

The construction technology of precast fabricated column-slab combined retaining wall adopts fabricated fabricated prefabricated slab-column combined structure,at the same time,different optimization is carried out according to different foundation structure,the temporary support step of the traditional precast column construction can be omitted,and the connection strength is high.When precast columns are used,the shear-resistant anchor tubes are installed in the deep foundation and extended sections are cast around the tubes to ensure the stability of the connecting sections.
