Anti-sedimentation control construction process for large-pipe-diameter rain and sewage pipeline of soft soil foundation
The invention discloses an anti-sedimentation control construction process for a large-pipe-diameter rain sewage pipeline of a soft soil foundation, and relates to the technical field of pipeline construction. According to the anti-sedimentation control construction technology for the large-pipe-diameter rain and sewage pipeline of the soft soil foundation, a bottom lime soil layer, a C25 concrete flat base layer and a C25 concrete shoulder base layer are included in the structure, and the bottom lime soil layer is formed by fully stirring soft foundation soil and quick lime to reach certain strength. According to the anti-sedimentation control construction technology for the large-pipe-diameter rain and sewage pipeline of the soft soil foundation, after the soft soil foundation at the bottom of the pipeline is replaced and filled by 300 mm, a lime soil layer is arranged, the strength of the foundation is improved, sedimentation is prevented, a C25 concrete flat foundation and a shoulder foundation are arranged on the bottom lime soil layer for construction, and the C25 concrete shoulder foundation is constructed after the strength reaches the standard after the C25 concrete flat foundation is constructed and maintained. During concrete shoulder foundation construction, grooves with the same rain sewage pipe diameter are reserved in the upper portion, and it is ensured that the bottom elevation of the grooves meets the requirement for the elevation of a design drawing of the bottom of a rain sewage pipeline.
本发明公开了一种软土地基大管径雨污水管道防沉降控制施工工艺，涉及管道施工技术领域。该软土地基大管径雨污水管道防沉降控制施工工艺，其在结构上包括：底部灰土层、C25混凝土平基层、C25混凝土肩基层，所述底部灰土层由软基土与生石灰充分搅拌后达到一定强度形成。该软土地基大管径雨污水管道防沉降控制施工工艺，通过将管道底部软土地基换填300mm后设置灰土层，增加地基强度防沉降，并在底部灰土层上设置C25混凝土平基与肩基施工，C25混凝土平基施工完成养护后强度达标后施工C25混凝土肩基，混凝土肩基施工时上部预留雨污水管径大小相同的凹槽，并确保凹槽底部标高符合雨污水管道底部设计图纸标高要求。
