Deep foundation pit permanent and temporary combined supporting structure and construction method thereof
The invention discloses a deep foundation pit permanent and temporary combined supporting structure which comprises fender posts, top beams, specially-made waist beam joints and specially-made concrete supporting joints, the specially-made waist beam joints are provided with externally-laid waterproof coiled materials, internally-preset side wall vertical steel bars and steel bar connectors, and water stop steel plates are arranged on the upper portions and the lower portions of the specially-made waist beam joints; floor slab horizontal steel bars are arranged in the specially-made concrete supporting nodes, steel bar connectors are arranged on the specially-made concrete supporting nodes, and water stop steel plates are arranged on the left and right; when a main body structure is constructed, the main body side wall reinforcing steel bars and the waist beam reinforcing steel bars can be connected through the reinforcing steel bar connectors, the waterproof coiled materials are in lap joint, and the main body floor reinforcing steel bars and the concrete supports can be connected through the reinforcing steel bar connectors. The method has the characteristic of permanent and temporary combination, permanent and temporary combination is achieved by presetting waterproof and structural connection conditions of a permanent stage for the temporary enclosure structure, the trouble of repeated support disassembly and replacement in traditional inner support design is avoided, the construction period is shortened, the manufacturing cost is reduced, and considerable economic benefits are achieved.
本发明公开了一种深基坑永临结合支护结构，包括围护桩、冠梁、特制腰梁节点和特制砼支撑节点，特制腰梁节点上设有外铺防水卷材、内预设侧墙竖向钢筋、并设置有钢筋接驳器、上下设有止水钢板；特制砼支撑节点上内设楼板水平钢筋、并设置有钢筋接驳器，左右设有止水钢板；在主体结构施工时，可将主体侧墙钢筋与腰梁钢筋通过钢筋接驳器连接起来，防水卷材进行搭接，可将主体楼板钢筋与砼支撑通过钢筋接驳器连接起来。该方法具有永临结合的特点，通过将临时围护结构预设永久阶段的防水和结构连接条件，实现永临结合，避免传统内支撑设计反复拆撑、换撑的麻烦，节省了工期，减小了造价，具有可观经济效益。
