Hanging cylinder type anchorage device structure rear mounting method for reducing excavation volume of foundation pit
The invention relates to the field of foundation pit excavation, and discloses a hanging cylinder type anchorage device structure rear-mounted installation method for reducing the foundation pit excavation volume, an anchorage device is arranged on the inner side of a pile body by arranging an installation space in the pile body, and therefore the problem that a protruding structure is formed by a traditional external anchor head is solved; the problems of increased excavation volume of the foundation pit, increased investment, long construction period, safety risk in implementation of the fertile groove and the like due to fertile groove filling are avoided; meanwhile, by means of a rear-mounted installation mode, it is effectively avoided that under the extrusion effect of liquid concrete, a pile body concrete pouring guide pipe is tightly attached to a hanging cylinder type anchorage device, so that a concrete guide pipe connecting flange is clamped by the device and cannot be pulled upwards, concrete pouring is delayed, and then the risk that a pile body is scrapped is avoided; and the problems that when concrete of the pile body is cast in place, the fluid concrete can form large buoyancy on the hanging cylinder type anchorage device embedded in the pile body, and if the hanging cylinder type anchorage device cannot be firmly fixed, the hanging cylinder type anchorage device deviates, floats upwards and the like can be easily caused can be solved.
本发明涉及基坑开挖领域，公开了一种用于减少基坑开挖量的挂筒式锚具结构后置安装方法，通过在桩体内部设施安装空间，将锚具设置在桩体内侧，从而解决了传统外置锚头所形成凸起构造，进而避免肥槽填充所增大的基坑开挖量、投资增加、工期较长及实施肥槽的安全风险等问题；同时，利用后置式的安装方式，有效避免桩体混凝土浇筑导管在液体混凝土挤压作用下，与挂筒式锚具密贴，导致混凝土导管连接法兰被本装置卡着而无法上拔，延误混凝土浇筑，进而避免桩体报废风险；也可避免，灌注桩体混凝土时，流态混凝土会对埋置于桩体内的挂筒式锚具形成较大浮力，如不能牢固将其固定，极易导致挂筒式锚具发生偏位、上浮等问题。
