Construction Technology of Manually Digging Cast-in-situ Pile in Weakly Weathered Rock or Medium Weathered Rock Area

Abstract

The present application relates to a construction technique for artificially digging holes for cast-in-place piles in weakly weathered or moderately weathered rock strata, including using a positioning casing and a drilling tool matched with the positioning casing to first excavate a central pile hole, and then use a slag collecting device to manually expand the hole. Hole steps. The beneficial effects of the present application are as follows: by using the positioning guard and the drilling tool, the central pile hole is first drilled, and when the central pile hole is drilled, the muck will be collected at the bottom of the positioning guard, and there is no need to manually shovel into the bucket again, At the same time, after the central pile hole is drilled, the muck collecting device is placed in the central pile hole, and then the periphery of the central pile hole is excavated and removed to expand the holes around. During the removal process, the muck is directly excavated. After entering the muck collecting device, it will be lifted to the ground after reaching a certain amount, which can save a lot of manpower and material resources and improve the efficiency of digging holes.

Description

Technical field [0001] The present application relates to the field of building piles drilled hole, particularly relates to a weakly weathered rock formation region or artificial weathering digging holes Pile Construction Technology. Background technique [0002] In a derivative of the big global situation of energy conservation, construction revolutionized the field of green building, which is characterized by four (energy, water, materials, land) a green. [0003] If this were done fast and efficient construction, also corresponds to an energy saving manner, in particular for digging post holes in the pile weakly weathered rock formation or weathered zone, how safe, rapid completion, it is to be solved problem. In the related art, there are a number of technical solutions to solve the above problems, however, the inventors have found that, in the related art, when using a substantially flush manner digging down the posts dug in the digging required artificial will keep the sedi...
