Construction device and method for hole forming of karst geological cast-in-place pile
The invention belongs to the technical field of underground building construction equipment, and particularly relates to a karst geology cast-in-place pile hole forming construction device and method.The karst geology cast-in-place pile hole forming construction device comprises a rotary spraying machine body, a drill rod and a spray head, the drill rod is installed on the rotary spraying machine body, and the spray head is detachably and fixedly installed at the end of the drill rod; the reinforced structure assembly is used for enhancing the bending strength of the jet grouting pile; the reinforcement cage is used as a reinforcement structure assembly, in the construction process of the jet grouting pile, the reinforcement cage is conveyed into the karst cave through the guide holes formed in the ground by means of the deformation capacity of the reinforcement cage, and the reinforcement cage is installed in the karst cave through the guide holes formed in the ground. And shape restoration is completed in the karst cave to form a framework structure, and then the cement slurry sprayed in a rotating mode is combined with the framework structure, so that the bending strength, the structural strength and other performance of the finally-manufactured jet grouting pile are enhanced.
本发明属于地下建筑施工设备技术领域，具体的说是一种岩溶地质灌注桩成孔的施工装置及方法，包括旋喷机主体、钻杆和喷头，所述钻杆安装在旋喷机主体上，所述喷头可拆卸式固定安装在钻杆端部；还包括增强结构组件，所述增强结构组件用于增强旋喷桩柱抗弯强度；定位安装组件，所述定位安装组件用于配合钻杆，将筋笼安装在溶洞中，本发明通过采用筋笼作为增强结构组件，在旋喷桩施工过程中，利用筋笼的变形能力，将筋笼通过开设在地面上的引孔，输送至溶洞内部，并在溶洞内部完成形状复原形成骨架结构，随后通过旋转喷射的水泥浆料与骨架结构进行结合，进而增强最终制成的旋喷桩的抗弯强度、结构强度等性能。
