Reverse underground engineering steel concrete pile-column vertical supporting device

YANG HUI / ZHENG ZHIFEI / XIONG WEI

The invention discloses a top-down underground engineering steel concrete pile-column vertical supporting device, and relates to the technical field of top-down underground engineering, the top-down underground engineering steel concrete pile-column vertical supporting device comprises a base, a concentric-square-shaped plate is slidably arranged on the upper surface of the base, a supporting mechanism is arranged between the base and the concentric-square-shaped plate, and a plurality of through holes are formed in the outer surface of the concentric-square-shaped plate in a surrounding mode; a plurality of through holes are formed in the upper end of the hollow-square-shaped plate, a concrete inserting rod is arranged in each through hole in a sliding mode, a pushing mechanism is arranged between the concrete inserting rods, a plurality of hollow-square-shaped molds are arranged at the upper end of the hollow-square-shaped plate in a sliding mode, and fixing mechanisms are arranged between the corresponding hollow-square-shaped molds and the hollow-square-shaped plate and between every two corresponding hollow-square-shaped molds. According to the concrete column, each concrete insertion rod is arranged in each through hole, and each concrete insertion rod is inserted into soil, so that the stability of the concrete column is improved, and the later inclination of the concrete column is prevented.

本发明公开了逆作地下工程钢砼以桩兼柱竖向支承装置，涉及逆作地下工程技术领域，包括底座，所述底座的上表面滑动设置有回形板，所述底座和回形板之间设置有支撑机构，所述回形板的外表面环绕开设有多个通孔，每个所述通孔的内部均滑动设置有混凝土插杆，每个所述混凝土插杆之间共同设置有推动机构，所述回形板的上端滑动设置有多个回形模具，对应的所述回形模具和回形板之间与对应的两个回形模具之间均设置有固定机构。本发明通过设置在每个通孔内部的混凝土插杆，将每个混凝土插杆插入到土壤的内部，提高混凝土柱的稳定性，从而防止混凝土柱后期倾斜。
