Manual hole digging cast-in-place pile construction process in weakly weathered rock or moderately weathered rock stratum area
The invention relates to a manual hole digging cast-in-place pile construction process in a weakly weathered rock or moderately weathered rock stratum area. The manual hole digging cast-in-place pileconstruction process comprises the steps that a positioning pile casing and a drilling tool matched with the positioning pile casing are adopted for digging a center pile hole, and then a muck collecting device is adopted for manual reaming. The construction process has the beneficial effects that the positioning pile casing and the drilling tool are adopted, the center pile hole is drilled firstly, muck can be collected at the bottom of the positioning pile casing when the center pile hole is drilled, and the muck does not need to be manually shoveled into a bucket again; meanwhile, after thecenter pile hole is drilled, the muck collecting device is placed into the center pile hole, and then the periphery of the center pile hole is excavated and shoveled to expand the hole towards the periphery; and in the shoveling process, the muck is directly excavated into the muck collecting device and then lifted to the ground after reaching a certain amount, a large amount of manpower and material resources can be saved, and the hole excavating efficiency is improved.
本申请涉及一种在弱风化岩或中风化岩层区域内人工挖孔灌注桩施工工艺，包括采用定位护筒和与定位护筒配合的钻具先挖掘中心桩孔再采用渣土收集装置人工扩孔的步骤。本申请的有益效果为：通过采用定位护筒以及钻具，先钻出中心桩孔，在钻中心桩孔时，渣土会被收集在定位护筒的底部，无需人工进行再次铲进吊桶，同时在中心桩孔钻完后，将渣土收集装置置入到中心桩孔内，然后再对中心桩孔周边进行挖掘和铲除，以向四周扩孔，在铲除的过程中，渣土直接挖掘进入渣土收集装置中，待达到一定量后再进行提升至地面，能够节省大量的人力物力，提高了挖孔效率。
