Sewage pipe pit excavation backfilling process and pipe pit excavation supporting structure
The invention relates to a sewage pipe pit excavation backfilling process and a pipe pit excavation supporting structure. According to the technical scheme, the sewage pipe pit excavation backfillingprocess is characterized by comprising the following steps that S1, construction preparation is carried out, specifically, a construction site is ascertained, surveying and setting out are carried out, and a pile position and a groove side line are determined; S2, pipe pit supporting and excavation are carried out, specifically, steel sheet piles are inspected, the axes of the steel sheet piles are determined, guide frames are installed, the steel sheet piles are driven, the steel sheet piles are buckled forwards and backwards to form two water retaining walls, the pipe pit is excavated for the first time, after a first fixing frame is arranged, excavation is carried out for the second time, after a second fixing frame is arranged, excavation is carried out for the last time, and a concrete cushion layer is poured at the bottom of the pipe pit; and S3, pipe pit backfilling and support removing are carried out, specifically, a pipeline is laid, coarse sand is adopted for manual backfilling and compacting in the range from the position above the cushion layer to the top of the pipeline, the second fixing frame is removed, then stone powder is adopted for mechanical backfilling, meanwhile, the first fixing frame is removed, and finally, the steel sheet piles are pulled out. According to the sewage pipe pit excavation backfilling process and the pipe pit excavation supporting structure, the effects of improving the stability of the pipe pit and preventing the pipe pit from collapsing are achieved.
本发明涉及一种污水管坑开挖回填工艺及管坑开挖支护结构，其技术方案要点是，包括以下步骤：S1施工准备：探明施工场地，测量放线，确定桩位及槽边线；S2管坑支护及开挖：对钢板桩进行检验，确定出钢板桩的轴线，并安装导向架，对钢板桩进行施打，使钢板桩正反相扣形成两道挡水墙，对管坑进行第一次开挖，并布设第一固定架后，再进行第二次开挖，布设第二固定架后，进行最后一次开挖，并在管坑底部浇筑混凝土垫层；S3管坑回填及拆除支护：铺设管道，在垫层以上至管道顶部范围内采用粗砂人工回填密实，拆除第二固定架，再采用石粉进行机械回填，同时对第一固定架进行拆除，最后对钢板桩进行拔除，达到提高管坑的稳定性，避免管坑出现坍塌的效果。
