Open caisson supporting construction method in comprehensive treatment process of underground drainage pipe
The invention relates to the technical field of open caisson supporting construction, in particular to an open caisson supporting construction method in the comprehensive treatment process of an underground drainage pipe, which comprises the following steps of: excavating a foundation pit by using a backhoe excavator, assisting in manual leveling, backfilling and tamping by using coarse sand in layers after the foundation pit is formed, and compacting by using a flat plate vibrator or a frog tamper so as to ensure the bearing capacity of filled sand; a sand cushion layer is laid for 3-5 times, and the sand cushion layer is vibrated and compacted through a flat plate vibrator; concrete is reinforced for the foundation, a ground groove is excavated manually, and the base is tamped; the prepared formwork is hoisted, then concrete is poured into the formwork and vibrated through an insertion type vibrating rod, a certain number of vibrating windows are formed in one side of the formwork so that the vibrating rod can enter the formwork for vibrating conveniently, and after the concrete below the windows is poured, the vibrating windows are closed immediately; and after the concrete strength meets the design requirement, sinking construction is conducted, the concrete cushion layer below the blade foot is chiseled away through the sub pickaxe, and then the concrete cushion layer is chiseled away.
本发明涉及沉井支护施工技术领域，一种地下排水管综合治理过程中沉井支护施工方法，包括用反铲挖土机进行基坑的挖掘，并辅助人工整平，基坑形成后以粗砂分层回填夯实，用平板振动器或蛙夯密实，以保证填砂的承载力；铺设砂垫层，分3到5次进行铺设，并采用平板振捣器振捣密实；地基加固混凝土，采用人工挖掘地槽，夯实基底；将准备好的模板进行吊装，然后将混凝土浇筑到模板中，并用插入式振捣棒进行振捣，且在模板一侧开一定数量的振捣窗，便于振捣棒入模振捣，浇筑完窗下部分混凝土后，立即封闭振捣窗；待混凝土强度达到设计要求后，进行下沉施工，先采用分镐凿除刃脚下的混凝土垫层，再凿除砼垫层。
