Cast-in-situ bored pile static pressure test pile head one-time pouring construction method
The invention discloses a cast-in-situ bored pile static pressure test pile head one-time pouring construction method, and belongs to the field of cast-in-situ bored piles. The cast-in-situ bored pilestatic pressure test pile head one-time pouring construction method comprises the following steps that S1, a hole forming steel casing is installed in a cast-in-situ bored pile formed hole; S2, the size of a reinforcement cage is designed; S3, the reinforcement cage is installed in the cast-in-situ bored pile formed hole; S4, concrete is poured into the formed hole; S5, a pile head steel casing is installed on the ground, and the hole forming steel casing is pulled out; S6, the concrete is continuously poured and vibrated to be compact to the top of the pile head steel casing; S7, the pile head is subjected to slurry collection and trowelling, and the cast-in-place pile is maintained; and S8, a static load test is carried out by using static load test equipment. According to the cast-in-situ bored pile static pressure test pile head one-time pouring construction method, the one-time pouring of the pile head of the cast-in-situ bored pile is adopted to replace a secondary pouring manufacturing process in the prior art, so that the construction period is shortened, the waste of materials is reduced, and the labor cost is reduced.
本发明公开了一种钻孔灌注桩静压试验桩头一次性浇筑施工方法，属于钻孔灌注桩领域，钻孔灌注桩静压试验桩头一次性浇筑施工方法包括如下步骤：S1、在灌注桩成孔内安装成孔钢护筒；S2、设计钢筋笼的尺寸；S3、将钢筋笼安装于钻孔灌注桩成孔内；S4、向成孔内灌入混凝土；S5、在地面上安装桩头钢护筒，拔出成孔钢护筒；S6、继续浇筑混凝土并振捣密实至桩头钢护筒筒顶；S7、桩头收浆抹平，对灌注桩进行养护；S8、使用静载试验设备进行静载试验。本发明公开的一种钻孔灌注桩静压试验桩头一次性浇筑施工方法，采用钻孔灌注桩桩头一次性浇筑完成代替现有技术中分二次浇筑制作工艺，缩短了施工工期，减少了材料的浪费，降低了人工成本。
