Construction method of multi-pile-hole combined steel platform capable of preventing slurry from overflowing
The invention discloses a construction method of a multi-pile-hole combined steel platform capable of preventing slurry from overflowing. The construction method comprises the following steps that a foundation pit is excavated; sinking a steel casing at the design position of each pile hole in the foundation pit; the upper end of each steel casing is sleeved with a pile hole cover plate, and a combined slurry groove is laid so that the pile hole cover plates can communicate with one another to form a multi-pile-hole combined steel platform; prefabricated concrete plates are laid in the remaining space of the adjacent pile hole cover plates; prefabricated concrete sleeper beams are hung on the periphery of the multi-pile-hole combined steel platform, and drilling pile machines are installed on the prefabricated concrete sleeper beams; and the drilling pile machine is controlled to drill and excavate soil bodies in all the steel casings in sequence, and generated slurry flows into the combined slurry groove through the pile hole cover plate to be collected and treated in a unified mode. The multi-pile-hole combined steel platform has the advantages that the multi-pile-hole combined steel platform is convenient to install and construct and is combined with a shallow foundation pit of a construction site for use, slurry in the circulating drilling process can be effectively guided and collected, and seepage and overflow of the slurry in the construction site are avoided.
本发明公开了一种可防泥浆外溢的多桩孔组合钢平台的施工方法，包括以下步骤：开挖基坑；在基坑内各桩孔的设计位置沉设钢护筒；分别在各钢护筒的上端部套装桩孔盖板，铺设组合式泥浆槽以将各桩孔盖板相互连通形成多桩孔组合钢平台；在相邻的桩孔盖板的剩余空间内铺设预制砼板；在多桩孔组合钢平台的外围四周吊放预制砼枕梁并在预制砼枕梁上安装钻孔桩机；控制钻孔桩机依次对各钢护筒内的土体进行钻孔开挖，所产生的泥浆经桩孔盖板流入组合式泥浆槽内进行统一收集处理。本发明的优点是：多桩孔组合钢平台安装施工便捷，同施工场地的浅基坑结合使用，可对循环钻孔过程中的泥浆进行有效的导流和收集，避免施工现场泥浆渗流外溢。
