Shed tunnel structure system suitable for road section prone to landslide and construction method of shed tunnel structure system
The invention relates to a shed tunnel structure system suitable for a road section prone to landslide and a construction method of the shed tunnel structure system, belongs to the technical field of shed tunnel supporting and solves the problems that in the shed tunnel construction process, landslide is prone to occurring, and the construction efficiency is low. The anti-slide piles are constructed at the temporary shortcut, the longitudinal beams are poured between the adjacent anti-slide piles for connection, and longitudinal connection between the adjacent anti-slide piles is completed; foundation trenches are sequentially excavated on the opposite side of the temporary shortcut in a segmented mode, and reinforced concrete pouring construction is conducted in the foundation trenches to form strip-shaped foundations; the prefabricated inclined columns and the prefabricated cross beams are transported to a construction site, and assembly type splicing installation is carried out; excavation of soil and stone bodies in the shed tunnel is conducted in a segmented mode; after excavation is completed, concrete pouring construction is conducted on the side walls, outer side longitudinal beams and a top plate of the shed tunnel; and a concrete bottom plate of the shed tunnel structure system is poured till construction of the whole shed tunnel structure system is completed. According to the method, excavation is conducted after supporting, disturbance is reduced, a shed tunnel structure system is rapidly spliced, and the construction efficiency is improved.
本发明涉及一种适用于易滑坡路段的棚洞结构系统及其施工方法，属于棚洞支护技术领域，解决了棚洞施工过程中易滑坡以及施工效率低的问题。本发明通过在临时便道处施工抗滑桩，相邻抗滑桩之间浇筑纵梁进行连接，完成相邻抗滑桩之间的纵向连接；在临时便道的对侧分段依次开挖基槽，在基槽中进行钢筋混凝土浇筑施工形成条形基础；将预制的斜柱和横梁运至施工现场，进行装配式拼接安装；分段进行棚洞内部土石体的开挖；挖掘完成后，对棚洞侧壁、外侧纵梁、顶板进行混凝土浇筑施工；浇筑棚洞结构系统的混凝土底板，直至完成全部棚洞结构系统的施工。本发明实现了先支后挖减少扰动，棚洞结构系统的快速拼接，提升了施工效率。
