Cast-in-situ bored pile close to subway shield construction section and construction method of fender pile system thereof
The invention provides a cast-in-situ bored pile close to a subway shield construction section and a construction method of a fender pile system of the cast-in-situ bored pile. Comprising the steps of construction preparation, pile position lofting, high-pressure jet grouting pile construction, guide support fixing, fender pile steel pipe inserting and driving, slurry preparation and circulating system construction, drilling and hole forming, hole cleaning, reinforcement cage machining and installation, sounding pipe installation, guide pipe installation, concrete pouring, cast-in-situ bored pile detection and the like. According to the invention, the shock absorption effect can be achieved on the constructed cast-in-situ bored pile, and the extrusion force on the pile body caused by shield construction is reduced.
本发明提供一种临近地铁盾构施工段钻孔灌注桩及其护桩体系施工方法，包括施工准备、桩位放样、高压旋喷桩施工、导向支架固定、护桩钢管插打、泥浆制备及其循环系统施工、钻进成孔、清孔、钢筋笼加工及安装、声测管安装、导管安装及混凝土浇筑、钻孔灌注桩检测等步骤。本发明能对已施工完成的钻孔灌注桩起到减震效果及减少因盾构施工对桩体产生的挤压力。
