Static expansion explosive pile head breaking method
The invention relates to a pile head breaking method in the technical field of blasting construction, which comprises the following steps: a pile foundation reinforcement cage is manufactured, the reinforcement cage comprises a plurality of main reinforcements, and a blanking guide pipe channel is formed in the reinforcement cage; a positioning ring is manufactured, the positioning ring and the reinforcement cage are fixed corresponding to the position of a pile head to be broken, the positioning ring comprises at least two ring bodies on the same plane, a plurality of first PVC pipes are fixed to the at least two ring bodies in the radial direction, the end portions of the two sides of each first PVC pipe in the length direction are sleeved with protective caps, and the protective caps are connected with the pile head to be broken. The part, corresponding to the to-be-broken pile head, of the main reinforcement is sleeved with a second PVC pipe; the reinforcement cage is subjected to concrete pouring to form a pile foundation; according to the method, the pile head is squeezed to be broken through the expansion explosives, the pile head is slightly trimmed, the regular and flat pile foundation top can be obtained, the danger caused by manual operation and direct operation of workers is greatly reduced, the construction efficiency is improved, and the construction cost is reduced. And meanwhile, the construction period can be greatly shortened.
本发明涉及爆破施工技术领域的一种桩头破除方法，包括步骤：制作桩基钢筋笼，所述钢筋笼包括多根主筋，所述钢筋笼内形成有下料导管通道；制作定位环，对应待破除桩头的位置将所述定位环与所述钢筋笼固定，所述定位环包括同一平面上的至少两个环体，在至少两个所述环体上径向固定多根第一PVC管，所述第一PVC管长度方向的两侧端部套设有保护帽，在主筋对应待破除桩头部分套设第二PVC管；对钢筋笼进行混凝土灌注形成桩基；取下第一PVC管伸出钢筋笼的一端端部的保护帽，利用膨胀炸药对桩头混凝土进行分离，本发明通过膨胀炸药挤断桩头并稍加修整就可以得到规则平整的桩基顶，极大的减少了人工操作和工人直接操作带来的危险性，同时也能大幅度缩短工期。
