Cutting retaining wall structure and construction method
The invention belongs to the technical field of excavation slope retaining, and particularly relates to a cutting retaining wall structure and a construction method. A cutting retaining wall structure comprises a retaining wall foundation, a retaining wall body poured on the top of the retaining wall foundation, and a first concrete layer, a second concrete layer and a third concrete layer which are sequentially poured on the back face of the retaining wall body; the drainage assembly comprises a plurality of first drainage pipes, a large-diameter second drainage pipe communicated with the water inlet ends of the first drainage pipes, and a steel wire mesh framework wrapping the periphery of the second drainage pipe. In order to solve the problems that a backfill layer of an existing cutting retaining wall is difficult to compact and unsmooth in drainage, the retaining assembly and the drainage assembly which consider the compaction degree of the backfill layer of the wall back, ensure smooth drainage of the wall back and quickly clean fine-grained soil accumulated at the bottom are provided, so that the compaction degree of the backfill layer at the wall heel of a retaining wall foundation is ensured; the defect that top shallow layer pores of the retaining wall backfill layer are prone to being blocked is overcome, and meanwhile the retaining wall backfill layer is kept smooth in overall drainage.
本发明属于挖方边坡支挡技术领域，具体涉及一种路堑挡土墙结构及施工方法。一种路堑挡土墙结构，包括：支档组件，包括挡墙基础、浇筑于所述挡墙基础顶部的挡墙墙身、依次浇筑于所述挡墙墙身背面的第一混凝土层、第二混凝土层和第三混凝土层；以及排水组件，包括多根第一排水管、与多根第一排水管进水端连通的大直径第二排水管和包裹于所述第二排水管外周的钢丝网骨架。本发明针对现有路堑挡土墙回填层难以压实和排水不畅的问题，提供兼顾墙背回填层压实度、保证墙背排水顺畅和快速清理底部积细粒土的支档组件及排水组件，从而确保挡墙基础墙踵处回填层的压实度，弥补墙背回填层顶部浅层孔隙易堵塞的不足，同时维持挡土墙回填层整体排水的顺畅。
