Cast-in-place pile karst cave treatment construction method
The invention relates to the field of karst caves, in particular to a cast-in-place pile karst cave treatment construction method.The cast-in-place pile karst cave comprises a karst cave, a pile hole is formed in the middle of the karst cave in a penetrating mode, a reinforcement cage is arranged in the pile hole, and the surface of the reinforcement cage is wrapped with a steel wire mesh; the fixing ring is placed on the upper surface of the square block, and reinforcing steel bars on the surface of a reinforcement cage are clamped between the two side blocks, so that the reinforcement cage can be quickly positioned through the T-shaped cylinder, the phenomenon that the reinforcement cage shakes in the working process is prevented, the use safety of the reinforcement cage is improved, meanwhile, the surface of the reinforcement cage is wrapped with a steel wire mesh, and the service life of the reinforcement cage is prolonged. The steel wire mesh bears the lateral pressure of a large amount of concrete, extrusion of the concrete on the newly formed hole wall of the karst cave section is greatly reduced, the occurrence of pile breaking and concrete loss caused by hole wall collapse is effectively reduced, meanwhile, the steel wire mesh can also play a role in preventing blockage and mud inclusion caused by hole wall collapse, and the concrete pouring quality is greatly improved.
本发明涉及溶洞领域，具体为一种灌注桩溶洞处理施工方法，包括溶洞，所述溶洞的中部贯穿设置有桩孔，所述桩孔的内部设置有钢筋笼，所述钢筋笼的表面包裹设置有钢丝网；本发明通过固定圈放置在方块的上表面，钢筋笼表面的钢筋卡接在两个侧面块之间，使得可快速通过T形筒对钢筋笼实现定位，防止钢筋笼在工作中发生晃动现象，提高钢筋笼的使用安全性，同时在钢筋笼的表面包裹设置有钢丝网，钢丝网承担了大量混凝土的侧压力，大大减少混凝土对溶洞段新形成孔壁的挤压，有效减少孔壁塌孔导致断桩、混凝土流失的发生，同时钢丝网还可以起到阻挡孔壁塌陷造成堵塞、夹泥，大大提升了混凝土浇筑的质量。
