Energy pile construction device for weakening mud cake effect and construction method thereof
The energy pile construction device capable of weakening the mud cake effect comprises a drill bit assembly, the drill bit assembly comprises a shaft rod, a drill bit, an expansion piece, a blasting piece, a driving piece and a splicing piece, the drill bit is fixed to the bottom end of the shaft rod, the expansion piece is arranged on the surface of the drill bit, the blasting piece is arranged on the shaft rod, and the driving piece is arranged on the shaft rod. The driving piece is fixed at the top end of the shaft rod, and the splicing piece is arranged on the driving piece; the connecting assembly is arranged at the end of the shaft rod and comprises a first communicating piece, a second communicating piece and a blocking piece. According to the energy pile, mud cakes are removed in the process of lifting a drill bit upwards through the drill bit assembly, meanwhile, the friction force of the energy pile can be improved, the sealing performance of an inner hole of the shaft rod is improved through the connecting assembly, and it is avoided that too many impurities enter the shaft rod, and follow-up use of the shaft rod is affected.
本发明公开了一种弱化泥皮效应的能源桩施工装置及其施工方法，包括钻头组件，包括轴杆、钻头、扩张件、爆破件、驱动件以及拼接件，所述钻头固定于所述轴杆底端，所述扩张件设置于所述钻头表面，所述爆破件设置于所述轴杆上，所述驱动件固定于所述轴杆顶端，所述拼接件设置于所述驱动件上；以及，连接组件，设置于所述轴杆端部，包括第一连通件、第二连通件以及堵塞件。本发明通过钻头组件的设置在将钻头向上提的过程中将泥皮去除，同时可提高能源桩的摩擦力，并通过连接组件的设置提高轴杆内部孔的密封性，避免过多的杂质进入轴杆内，影响其后续使用。
