Step type river channel revetment construction method suitable for deep soft soil stratum
The invention discloses a construction method of a stepped river channel revetment suitable for a deep soft soil stratum, which is specifically implemented according to the following steps: firstly excavating river channel sludge along a river channel according to an excavation line, and then carrying out riprap silt extrusion treatment; sludge covering the upper layer of the stone is cleaned up, and block stone backfilling treatment is conducted on the stone layer; a concrete cushion layer is poured after block stone backfilling treatment; first-stage retaining wall foundation formwork erecting operation is conducted, first-stage retaining wall body structure construction is conducted, a PVC drainage pipe a is pre-buried in the first-stage retaining wall, and an inverted filter bag is installed at the end of the drainage pipe a; first-time wall back soil backfilling operation is conducted, a second-stage retaining wall foundation is poured, second-stage retaining wall body structure construction is conducted, a PVC drainage pipe b is pre-buried in the second-stage retaining wall, and an inverted filter bag is installed at the end of the drainage pipe b; and second-time wall back backfill soil operation is conducted, and second-time wall back backfill soil is connected with the original embankment. The construction requirements of river slope protection and effective flood discharge can be met, and meanwhile, a guiding value is brought to river regulation.
本发明公开了一种适用于深软土地层的台阶式河道护岸施工方法，具体按照以下步骤实施：先沿着河道按照开挖线开挖河道淤泥，完成后进行抛石挤淤处理；将覆盖于石块上层的淤泥清理干净，在石块层上面进行块石回填处理；块石回填处理后浇筑混凝土垫层；进行第一级挡墙基础支模作业，进行第一级挡墙墙身结构施工，第一级挡墙预埋PVC排水管a，排水管a端部安装反滤包；进行第一次墙背回填土作业，浇筑第二级挡墙基础，第进行第二级挡墙墙身结构施工，第二级挡墙预埋PVC排水管b，排水管b端部安装反滤包；进行第二次墙背回填土作业，使第二次墙背回填土与原堤岸相接。能满足河道边坡防护、有效行洪的建设要求，同时为河道治理带来指导价值。
