Assembly type foundation pit inner supporting structure and grouting construction method thereof
The invention relates to the technical field of foundation pit supporting, and discloses an assembly type foundation pit inner supporting structure and a grouting construction method thereof.The assembly type foundation pit inner supporting structure comprises a bearing piece, a supporting piece and a fixing piece, and the supporting piece comprises a first supporting part and a plurality of second supporting parts; the fixing piece comprises a first fixing part and a second fixing part; the bearing piece, the supporting piece and the fixing piece each comprise a hollow shell, reinforcing steel bars are preassembled in the shells, communicating holes communicating with one another are formed among the bearing piece, the first supporting part, the second supporting part and the fixing piece, and grouting holes are formed in the top of the first supporting part and the top of the second fixing part. The integral structure of the foundation pit support is simplified, the reinforcement cage can be directly formed by reinforcing steel bars during prefabrication forming in a factory, the process of manually binding the reinforcement cage is avoided, meanwhile, the bearing piece, the supporting piece and the fixing piece are of hollow structures, the grouting process is reserved in site construction, the quality of prefabricated pieces in the factory is reduced, manufacturing and transportation cost is reduced, and the construction efficiency is improved. And light-weight manufacturing is realized.
本发明涉及基坑支护技术领域，公开了一种装配式基坑内支撑结构及其注浆施工方法，包括：承托件、支撑件和固定件，支撑件包括第一支撑部和若干个第二支撑部；固定件包括第一固定部和第二固定部；承托件、支撑件与固定件均包括空心的壳体，壳体内预装配有加强钢筋，承托件、第一支撑部、第二支撑部与固定件之间均设置有相互连通的连通孔，第一支撑部以及第二固定部的顶部均设置有注浆孔。简化了基坑支护的整体结构，在工厂内预制成型时可直接由加强钢筋形成钢筋笼，避免了人工绑扎钢筋笼的过程，同时承托件、支撑件和固定件为空心结构，将注浆过程预留在现场施工，减小了工厂内预制件的质量，减小了制作、运输的成本，实现了轻量化制作。
