Pile sinking construction method for drilling and implanting precast pile
According to the pile sinking construction method for precast pile drilling implantation, an orifice integrated platform is of a profile steel combined structure and has the functions of limiting adjustment, precast pile temporary fixing and later concrete pouring guide pipe bearing, a hoop device is arranged during pile sinking and used for fixing a precast pipe pile, pile splicing and the like, a hoop is dismantled before concrete pouring, and the construction efficiency is improved. The support points of the structure are peripheral soil bodies and are fixed by driving steel piles and the like. According to the method, mature processes are ingeniously combined, major dangerous sources are not involved in the construction process, used machine tools and equipment are conventional, and the construction safety risk is reduced. Compared with cast-in-situ bored pile construction, the implanting method of firstly drilling and implanting the pile and then filling the joint is adopted, so that the manufacturing cost can be reduced, and the construction period can be shortened. And the application range is wide, when the geology is hard, a broken pebble-containing layer or a supporting layer is a rock layer, and a precast pile is difficult to hammer or press the pile to sink, the implanting method can be adopted for construction, and good applicability is achieved.
本发明提供了一种预制桩钻孔植入的沉桩施工方法，孔口一体化平台为型钢组合结构，兼具限位调整、临时固定预制桩以及用于后期承托混凝土浇筑导管的功能，沉桩时设有抱箍装置，用于固定预制管桩、接桩等，浇筑混凝土前拆除抱箍，此结构的支座点为周边的土体，采用打入钢桩等固定。该方法成熟工艺的巧妙组合，施工过程不涉及重大危险源，使用的机具设备也均为常规，降低了施工安全风险。相比钻孔灌注桩施工，采用本先钻孔植桩后填缝的植入法，可降低造价和缩短施工周期。适用范围广，对于地质较为坚硬、含碎卵石层或持力层为岩层，预制桩锤击或压桩下沉困难时，可采用本植入法施工，具有较好的适用性。
