UHPC-NC composite structure underground diaphragm wall structure and construction method
The invention discloses a UHPC-NC composite structure underground diaphragm wall structure and a construction method. The UHPC-NC composite structure underground diaphragm wall structure is formed by vertically overlapping and fixedly connecting single-layer underground diaphragm walls. The single-layer underground diaphragm wall is formed by arranging and connecting a plurality of caisson units, connecting box units and corner column units, the opposite faces of all unit components on the same layer are connected through convex rails and guide grooves which are matched with each other, and all the unit components which are adjacent up and down are fixedly connected through corresponding wall face splicing boxes and corner column splicing boxes. Mutually matched clamping pieces are arranged between the transversely adjacent wall surface splicing boxes as well as between the corner post splicing boxes and the wall surface splicing boxes; all the components are made of UHPC materials, and filling bodies are arranged in inner cavities of the components. The construction method can be one-time sinking after the complete single-layer underground diaphragm wall is assembled, and can also be sequential sinking of all the components. The method is high in quality, high in efficiency, low in cost and low in influence; extremely high corrosion resistance and durability are realized; and factory prefabrication and assembly type construction are adopted, the material consumption is reduced, carbon emission is reduced, and social benefits and economic benefits are remarkable.
一种UHPC‑NC组合结构地下连续墙构型及施工方法，由单层地下连续墙竖向叠合且固定连接而成。单层地下连续墙由多个沉箱单元、连接箱单元及角柱单元排列连接而成，同层各单元构件相向面由相互配合的凸轨及导槽连接，上下相邻的各单元构件经对应的墙面拼接箱、角柱拼接箱固定连接，横向相邻的墙面拼接箱之间及角柱拼接箱与墙面拼接箱之间有相互配合的卡接件；所有构件均采用UHPC材料制成，构件内腔具有填充体。施工方法可以是装配成完整的单层地连墙后一次下沉，也可以是各构件次序下沉。本发明高质量、高效率、低成本、低影响；具有极高的耐腐蚀性和耐久性；工厂预制，装配式施工，减少材料用量，降低碳排放，社会效益和经济效益显著。
