Underground structure permanent and temporary combined supporting system and construction method
The invention relates to the technical field of subway supporting structures, and discloses an underground structure permanent-temporary combined supporting system and a construction method, and the underground structure permanent-temporary combined supporting system comprises an enclosure structure, a top plate, a middle plate, a bottom plate and side walls; the top plate comprises a top beam, a first longitudinal beam and a plurality of first transverse supports, and the first transverse supports are arranged at intervals in the length direction of the first longitudinal beam; the middle plate comprises a waist beam, a second longitudinal beam and a plurality of second transverse supports, and the second transverse supports are arranged at intervals in the length direction of the second longitudinal beam; permanent structural slabs are arranged between every two adjacent first cross braces and between every two adjacent second cross braces, and the permanent structural slabs are prefabricated slabs or cast-in-place slabs formed through modular suspended formwork pouring. Each permanent structural slab is formed by a prefabricated slab or a cast-in-place slab poured by a modular suspended formwork, a laminated layer structure is avoided, and steel bars do not need to be bound again and concrete does not need to be poured again during back building; the permanent structural slab is formed through one-time pouring, temporary steel bars or exposed reserved tie bars do not need to be arranged, and steel bar waste and rusting are reduced.
本发明涉及地铁支护结构技术领域，公开了一种地下结构永临结合支护系统及建造方法，包括围护结构、顶板、中板、底板和侧墙；顶板包括冠梁、第一道纵梁和第一道横撑，第一道横撑沿第一道纵梁的长度方向间隔布置有多个；中板包括腰梁、第二道纵梁和第二道横撑，第二道横撑沿第二道纵梁的长度方向间隔布置有多个；相邻的两个第一道横撑之间、两个第二道横撑之间均布置有永久结构板，永久结构板为预制板或采用模块化吊模浇筑形成的现浇板。永久结构板均采用预制板或采用模块化吊模浇筑的现浇板形成，无叠合层结构，在回筑时无需再次绑扎钢筋、浇筑混凝土；永久结构板一次浇筑成型，不需要布置临时钢筋或者外露预留拉筋，减少钢筋浪费以及生锈。
