Large-area rockfill area rotary digging hole-forming cast-in-place pile construction technology
The invention discloses a large-area rock-filled area rotary excavating hole-forming cast-in-place pile construction technology, and relates to the technical field of building construction, the large-area rock-filled area rotary excavating hole-forming cast-in-place pile construction technology comprises the following steps: 1, selecting a construction position in a rock-filled area; 2, a rotary drilling machine is adopted for hole forming operation; 3, after hole forming is completed, hole cleaning operation is conducted; 4, a cylindrical steel cylinder is placed in the formed hole, and the bottom end of the steel cylinder tightly presses the bottom wall of the formed hole; 5, water-stable mortar is poured into the space between the steel cylinder and the hole wall of the formed hole through high-pressure grouting equipment, and a hole wall reinforcing layer is formed; 6, after the hole wall reinforcing layer is formed, the steel cylinder is dismantled; 7, the bound reinforcement cage is put into the formed hole, and stirred concrete is poured into the hole to form a cast-in-place pile; and 8, after grouting is completed, concrete is subjected to curing operation. The structural strength and stability of the cast-in-place pile under the complex geological condition are ensured, and the construction quality is improved.
本申请公开了一种大面积填石区域旋挖成孔灌注桩施工工艺，涉及建筑施工的技术领域，其包括以下步骤：步骤1、在填石区域选定施工位置；步骤2、采用旋挖机进行成孔作业；步骤3、成孔完成后，进行清孔作业；步骤4、在成孔内放入柱形的钢筒，且使钢筒的底端压紧成孔的底壁；步骤5、采用高压注浆设备向钢筒与成孔孔壁之间的空间内灌注水稳砂浆，形成孔壁加固层；步骤6、待孔壁加固层成型后，将钢筒拆除；步骤7、将绑扎好的钢筋笼放入成孔内，并向孔内灌注搅拌好的混凝土，形成灌注桩；步骤8、灌浆完成后，对混凝土进行养护作业。本申请确保了灌注桩在复杂地质条件下的结构强度和稳定性，提高了施工质量。
