Cast-in-place pile structural frame, cast-in-place concrete pile and construction method of cast-in-place concrete pile
The invention provides a cast-in-place pile structural frame, a cast-in-place concrete pile and a construction method of the cast-in-place concrete pile. The cast-in-place pile structure frame is used for the karst area and comprises a pile casing, a reinforcement cage and at least one corrugated pipe, the pile casing is arranged outside the reinforcement cage in a sleeving mode and corresponds to the first karst cave, the corrugated pipe is made of plastic, and the pipe wall of the corrugated pipe is of a concave-convex alternating structure in the axial direction. The corrugated pipes are arranged outside the reinforcement cage in a sleeving mode and connected with the reinforcement cage, the corrugated pipes correspond to the second karst caves in position, and the two ends of each corrugated pipe protrude out of the corresponding second karst caves. The pile casing is arranged at the first karst cave located at the lowest position, and the corrugated pipe is arranged at the second karst cave located at the upper position, so that concrete is prevented from flowing into the karst caves in the pouring process, backfilling is avoided, the construction efficiency is improved, and the construction cost is reduced; the corrugated pipe is made of plastic materials, low in cost, good in corrosion resistance and light in weight, the corrugated pipe can be installed on the reinforcement cage on the ground, the corrugated pipe and the reinforcement cage are integrally hoisted and placed into a pile hole, and construction is convenient.
本发明提供一种灌注桩结构架、混凝土灌注桩及混凝土灌注桩的施工方法。灌注桩结构架，用于岩溶地区，包括护筒、钢筋笼及至少一个波纹管，护筒套设在钢筋笼外并与第一溶洞对应设置，所述波纹管为塑料材质，其管壁沿轴向呈凹凸交替结构；波纹管套设在钢筋笼外，且二者相连接，各波纹管与各第二溶洞相对应位置处，其两端均突出于对应的第二溶洞。位于最下方的第一溶洞处设置护筒、位于上方的第二溶洞处设置波纹管，来阻止灌注过程中混凝土流入溶洞，避免了回填，提高施工效率，且降低了施工成本；波纹管为塑料材质，成本低，具有较好的耐腐蚀性，且质量较轻，可以在地面上将波纹管安装至钢筋笼上，并与钢筋笼整体吊装并放入桩孔，方便施工。
