Block combination structure of fabricated open trench tunnel
The invention discloses a block combination structure of a fabricated open trench tunnel. The block combination structure of the fabricated open trench tunnel at least comprises a cast-in-place bottomplate, a prefabricated top plate, a prefabricated left side wall, a prefabricated middle partition wall and a prefabricated right side wall. The cast-in-place bottom plate is adopted, the number of joints is effectively reduced, and the block combination structure is beneficial to waterproofing; and an arched inverted-T-beam is adopted in the top plate to optimize the structural stress, the platethickness is effectively reduced, the lifting weight of a block is reduced, and the block combination structure of the fabricated open trench tunnel meets rapid construction requirements in a city. The horizontal force is mainly borne by a first underground wall and a second underground wall, and the prefabricated left side wall, the prefabricated right side wall and the prefabricated middle partition wall mainly bear the vertical axial force.
本发明公开了一种装配式明挖隧道的分块组合结构，至少包括现浇底板、预制顶板、预制左侧墙、预制中隔墙和预制右侧墙。本发明采用现浇底板可有效减少接缝数量，利于防水；顶板采用起拱倒T梁可优化结构受力，有效减少板厚，从而减小分块的吊装重量，适应于城市内快速施工建设的需求；水平力主要由第一地下墙和第二地下墙承担，预制左侧墙、预制右侧墙及预制中隔墙以承担竖向轴力为主。
