Fabricated high-pressure jet grouting variable-diameter telescopic reinforcement cage expansion anchor cable construction method
The invention relates to the technical field of constructional engineering, and discloses an assembly type high-pressure jet grouting variable-diameter telescopic reinforcement cage expanded anchor cable construction method which comprises the following steps: S1, geological exploration is performed on a construction site, the structural conditions of pipelines, buildings and other public facilities near a project are known, and pipelines needing to be moved and modified are moved and modified; electrifying, passing, water passing and land leveling of the construction site are completed; and S2, measuring the elevation, calculating the rotary drilling depth, placing a rotary drilling rig in place, performing rotary drilling, and shifting the drilling rig after hole forming is completed. According to the assembly type high-pressure jet grouting variable-diameter telescopic reinforcement cage expansion anchor cable construction method, the reinforcement cage is arranged behind the high-pressure jet grouting pile for construction, so that the strength of the pile body is higher, the pile body can be used as a bearing foundation pile after being arranged in the reinforcement cage, the construction cost is relatively lower than that of a cast-in-situ bored pile, variable-diameter telescopic can be carried out through the expansion anchor cable, the technology is mature, the construction speed is high, and the construction efficiency is high. And the construction cost is low, and certain social benefits and economic benefits are achieved.
本发明涉及建筑工程技术领域，且公开了一种装配式高压旋喷变径伸缩钢筋笼扩体锚索施工方法，包括以下步骤：S1:对施工地进行地质勘查并了解工程附近管线、建筑物和其他公共设施的结构情况，对需要迁改的管线进行迁改，完成施工场地的通电、通路、通水和土地平整；S2:测定标高，计算旋挖深度，旋挖钻机就位，旋转挖进，成孔完毕后钻机移位。该装配式高压旋喷变径伸缩钢筋笼扩体锚索施工方法，通过高压旋喷桩后置钢筋笼施工，使桩体强度更高，置入钢筋笼后，可作为承载基桩采用，较钻孔灌注桩造价相对较低，并可通过扩体锚索进行变径伸缩，技术成熟、施工速度较快，且施工成本较低，具有一定的社会效益和经济效益。
