Excavating and supporting method for comprehensive pipe gallery water collecting pool
The invention relates to the technical field of foundation pit excavation supporting construction, in particular to a comprehensive pipe gallery water collecting pool excavation supporting method. S1, excavating a comprehensive pipe gallery foundation pit at the water collecting tank to the base surface of the comprehensive pipe gallery; s2, surveying and setting out; s3, mounting a steel enclosing purlin; s4, burying filter pipes and well point pipes around the water collecting tank, mounting a header pipe, connecting a vacuum pump, and dewatering and draining water; s5, shallow soil is excavated, ring beam steel bars are bound, a formwork is erected, a steel calandria is installed, preformed holes are reserved, and concrete is poured; s6, earthwork under the crown beam is excavated in the opposite direction in a segmented mode, brick walls are built in a segmented mode, plastering is conducted after brick mold building is completed, and backfilling and grouting are conducted in reserved holes; s7, a cushion layer is poured; and S8, primary construction of the water collecting tank structure. The method is low in construction cost, the construction period is short, the working environment is improved, the accident occurrence probability is reduced, and the method is mainly applied to excavation and supporting of the comprehensive pipe gallery water collecting pool.
本发明涉及基坑开挖支护施工技术领域，更具体而言，涉及一种综合管廊集水池开挖支护方法。S1、集水池部位综合管廊基坑开挖至综合管廊基底面；S2、测量放线；S3、安装钢围檩；S4、集水池四周埋设滤管、井点管，安装总管，连接真空泵，降排水；S5、开挖浅层土，绑扎圈梁钢筋，架立模板，安装钢排管，留设预留孔，浇筑混凝土；S6、对向分段开挖冠梁下土方，分段砌筑砖墙，砖模砌筑完成后抹面，预留孔内回填灌浆；S7、浇筑垫层；S8、集水池结构一次施工。该方法施工成本较低，工期占用较短，提高了作业环境，降低事故发生概率本发明主要应用于综合管廊集水池开挖支护方面。
