Full-casing hydraulic hammering soil-squeezing cast-in-place pile device and construction method thereof
The invention relates to a full-casing hydraulic hammering soil-squeezing cast-in-place pile device and a construction method thereof. The full-casing hydraulic hammering soil-squeezing cast-in-placepile device comprises an outer casing and a hydraulic hammer connected into the outer casing in a sleeve mode, wherein an inner pile tip is fixedly arranged at the bottom of the hydraulic hammer, correspondingly, an outer casing pile shoe abutting against the side wall of the inner pile tip is fixedly arranged at the bottom of the outer casing, and the hydraulic hammer drives the inner pile tip tomove downwards so as to drive the outer sleeve and the outer sleeve pile shoe to move downwards synchronously. According to the full-casing hydraulic hammering soil-squeezing cast-in-place pile device and the construction method thereof, the structure is simple, the design is reasonable, on one hand, the work amount of outward transportation of earthwork and mud is reduced to the maximum extent,pollution of the building muck and mud to the surrounding environment is avoided, on the other hand, the pile end bearing capacity and the pile side friction force of foundation soil are improved through compaction of a soil body, the use amount of piles is reduced, therefore, compared with various existing pile foundation construction methods, the construction method has the advantage that the work efficiency is improved by times or above.
本发明涉及一种全套管液压锤击挤土灌注桩装置及其施工方法，包括外套管，套接于外套管内的液压锤，液压锤底部固设有内桩尖，与此相对应的，外套管底部固设有与内桩尖侧壁相抵接的外套管桩靴；液压锤驱动内桩尖向下移动，进而带动外套管和外套管桩靴同步向下移动；本发明结构简单，设计合理，一方面最大幅度地减少土方和泥浆外运的工程量，避免了建筑渣土和泥浆对周边环境的污染，另一方面土体的挤密使地基土的桩端承载力和桩侧摩擦力提高，减少了桩的使用量，因而采用该施工方法的工效比现有各类桩基施工方法均有成倍以上提高。
