Construction method for hole guiding and pile planting through down-the-hole hammer
The invention discloses a construction method for hole guiding and pile planting through a down-the-hole hammer, and belongs to the technical field of building construction. The construction method for down-the-hole hammer hole guiding and pile planting comprises a down-the-hole hammer construction system and further comprises the following steps that S1, the down-the-hole hammer construction system and an inspection system are installed; S2, hole guiding is conducted through a down-the-hole hammer, and a down-the-hole hammer drilling tool is taken out; S3, cement is poured into a hole; S4, hole opening drilling slag is cleaned, and cement is added for stirring; S5, the stirred cement soil is injected into the guide hole for backfilling; S6, the steps S1-S5 are repeated, all pile holes are completed, and backfilling and compacting are conducted; S7, a static pressure or hammering pile machine is adopted for pipe pile implanting construction; and S8, after the pile is maintained, a pile foundation static load test is conducted. According to the construction method for hole guiding and pile planting through the down-the-hole hammer, the construction technical difficulty that the pipe pile enters a strongly-weathered rock stratum to reach a moderately-weathered rock stratum is solved, the construction period is guaranteed, and meanwhile the construction quality of the pipe pile is guaranteed.
本发明公开了一种潜孔锤引孔植桩的施工方法，属于建筑施工技术领域，潜孔锤引孔植桩的施工方法包括潜孔锤施工系统，此外还包括如下步骤：S1、安装潜孔锤施工系统，检查系统；S2、通过潜孔锤进行引孔，取出潜孔锤钻具；S3、向孔内倾倒水泥；S4、清理孔口钻渣并加入水泥进行搅拌；S5、将搅拌后的水泥土注入引孔中进行回填；S6、重复步骤S1‑S5，完成所有桩孔并回填密实；S7、采用静压或锤击桩机进行管桩植入施工；S8、对桩养护后进行桩基静载试验。本发明公开的一种潜孔锤引孔植桩的施工方法，解决了管桩进入强风化岩层到达中风化岩层的施工技术难点，确保了施工工期，同时保证了管桩的施工质量。
