Construction method of manual hole digging pile
The invention relates to the technical field of concrete pile construction, in particular to a construction method of a manual hole digging pile. The method is characterized in that a plurality of pile head breaking holes are reserved in a concrete retaining wall during construction of a pile hole and the concrete retaining wall, the pile head breaking holes mainly play a role in breaking and positioning a pile head, during pile head breaking construction, the pile head breaking position can be accurately determined, and the pile head breaking efficiency is improved. Meanwhile, during pile head breaking construction, a reinforcing steel bar is inserted into the two pile head breaking holes in the same straight line firstly, then a breaking device acts on all the reinforcing steel bars to break the pile head, the reinforcing steel bars serve as supporting acting pieces, and therefore the breaking device can conduct pile head breaking construction conveniently. In addition, the pile head can be broken more easily on the plane where the pile head breaking holes are formed, the requirements for the breaking device, manpower and material resources are effectively lowered, damage to a pile body and the reinforcing steel bars is also reduced, and the quality of the pile body is guaranteed.
本发明涉及混凝土桩施工技术领域，尤其是一种人工挖孔桩的施工方法，该施工方法通过在桩孔以及混凝土护壁的施工时，在混凝土护壁上预留出多个桩头破除孔，桩头破除孔主要起桩头破除定位作用，使得在桩头破除施工时，能够准确确定桩头破除位置，提高桩头破除效率；同时，在桩头破除施工时，先在同一直线上的两个桩头破除孔中插入一根钢筋，然后通过破除装置作用在所有钢筋上，对桩头进行破除，通过钢筋作为支撑作用件，方便破除装置进行桩头破除施工，并且，桩头也更容易在桩头破除孔所处的平面断裂，有效地降低了对破除装置、人力和物力的要求，也降低对桩体以及钢筋的损伤，保证桩体的质量。
