Open cut tunnel over-crossing existing culvert structure and construction method thereof
The invention discloses an open-cut tunnel over-crossing existing culvert structure and a construction method thereof. The open-cut tunnel over-crossing existing culvert structure comprises an existing culvert; the tunnel structure is arranged above the existing culvert in an oblique crossing manner; the pile foundations bear the tunnel structure; the protection structure comprises slope making modules and supporting modules, the slope making modules and the supporting modules are matched to define the range of the tunnel structure, the slope making modules are arranged at the two intersections of the tunnel structure and the existing culvert respectively, and the supporting modules are adjacent to the slope making modules and arranged at the other positions in the range. The slope making modules are locally adopted and matched with the supporting modules to define the foundation pit type, the scale of the foundation pit is reduced, the good earth surface deformation control capacity is achieved, the pile foundations bear the vertical load of the tunnel structure, an existing culvert and a newly-built tunnel are independent stress systems respectively, mutual influence of the existing culvert and the newly-built tunnel is avoided, and the construction efficiency is improved. And the safety of the existing culvert and the newly-built tunnel in a long-term use period after completion is ensured.
本发明公开了一种明挖隧道上跨既有涵洞结构及其施工方法，明挖隧道上跨既有涵洞结构包括：既有涵洞；隧道结构，斜交设置在既有涵洞的上方；若干桩基，承载隧道结构；防护结构，包括放坡模块和支护模块，放坡模块和支护模块相配合限定出隧道结构的范围，放坡模块分别设置在隧道结构与既有涵洞的两个相交处，支护模块相邻于各放坡模块设置在范围内的其余位置。通过局部采用放坡模块，并与支护模块配合围成基坑型式，减小了基坑规模，具有良好的控制地表变形能力，通过由桩基承受隧道结构的竖向荷载，使既有涵洞和新建隧道各自为独立的受力体系，避免了两者的相互影响，保证既有涵洞与新建隧道在完成后长期使用期的安全。
