Assembled integral type underground structure and construction method
The invention discloses an assembled integral type underground structure and a construction method, and the underground structure comprises a cast-in-place bottom plate structure at the lower part between prefabricated side walls, a prefabricated middle plate structure at the middle part, and a top plate structure which is formed by overlapping prefabricated and cast-in-place at the top, lower-layer structural columns and upper-layer structural columns are respectively arranged among the cast-in-place bottom plate structure, the prefabricated middle plate structure and the top plate structure; prefabricated and cast-in-place superposed middle longitudinal beams and top longitudinal beams are respectively arranged at the tops of the structural columns; the construction method comprises the following steps that the enclosure structure is constructed, and the foundation pit is excavated; assembling the prefabricated side wall; a bottom plate structure is poured; lowering a lower-layer structural column; prefabricated middle longitudinal beams are erected, and prefabricated middle plates are erected; lowering an upper-layer structural column; pouring a superposed middle longitudinal beam; erecting a prefabricated top longitudinal beam; erecting a prefabricated top plate; pouring a top plate laminated layer and a laminated top longitudinal beam; pre-stress tensioning is conducted; and constructing an upper-layer structure and backfilling. Integral assembly is realized, the construction efficiency is improved, the construction quality is improved, the construction period is shortened, and the cost is reduced.
本发明公开了一种装配整体式地下结构及施工方法，其地下结构包括预制侧墙之间下部的现浇底板结构、中部的预制中板结构、顶部的预制和现浇叠合一起的顶板结构，现浇底板结构、预制中板结构、顶板结构之间分别设置有下层结构柱、上层结构柱，结构柱的顶部分别设有预制和现浇叠合一起的中纵梁和顶纵梁；其施工方法，包括以下步骤：施做围护结构，开挖基坑；拼装预制侧墙；浇筑底板结构；下放下层结构柱；架设预制中纵梁，搭设预制中板；下放上层结构柱；浇筑叠合中纵梁；架设预制顶纵梁；搭设预制顶板；浇筑顶板叠合层和叠合顶纵梁；预应力张拉；施工上层结构并回填。本发明实现装配整体式，提高施工效率，改善施工质量，缩短工期降低成本。
