Cast-in-situ bored pile and inner support supporting structure construction method for rail transit station
The invention belongs to the field of deep foundation pit supporting, and particularly discloses a cast-in-situ bored pile and inner support supporting structure construction method for a rail transitstation. Construction preparation is conducted, specifically, site leveling is conducted according to the site pavement condition, then pile hole setting-out is conducted, and pile casing burying isconducted before drilling; mud preparation is conducted, specifically, according to the preset proportion, the mud is prepared; drilling is conducted, specifically, drilling operation is conducted continuously without interruption; after drilling is completed, the hole depth, the hole diameter, the hole position, the hole shape and the like of a hole are detected and cleaned; a reinforcement cageis manufactured and hoisted, specifically, the reinforcement cage is manufactured on site according to preset requirements and hoisted according to preset hoisting points; a guide pipe, a funnel and amaterial storage hopper are installed; and underwater concrete pouring is conducted, specifically, the volume of bottom sealing concrete is calculated firstly, then underwater concrete pouring is conducted, and pile hole backfilling is conducted after pouring of cast-in-place pile concrete is completed. The method has the characteristics of stable supporting, small deformation, simple construction operation, high working efficiency and the like.
本发明属于深基坑支护领域，并具体公开了一种轨道交通车站钻孔灌注桩和内支撑支护结构施工方法。施工准备：根据现场路面情况进行场地平整，然后进行桩孔放样，钻孔前先进行埋设护筒，泥浆制备：按照预设配比进行泥浆的制备，钻孔，钻孔作业保持连续进行，不中断；钻孔完成后，对孔的孔深、孔径、孔位和孔形等进行检测，清孔，钢筋笼的制作与吊放：按照预设要求现场制作钢筋笼，并按照预设的吊点进行钢筋笼的吊放；导管、漏斗、储料斗安装，浇注水下砼：首先计算封底混凝土的体积，然后进行水下砼的灌注，灌注桩砼浇注完后，进行桩孔回填。本发明具有支护稳定、变形小、施工操作简便、工作效率高等特点。
