Tunnel underpass concrete pipe ditch bearing platform load underpinning protection construction method
The invention discloses a tunnel underpass concrete pipe ditch bearing platform load underpinning protection construction method, and belongs to the field of building construction engineering. The method mainly comprises the steps that after the construction of a tunnel main body structure (except for reserved holes of supporting piles) is completed, a brick mold is built between a tunnel top plate and a pipe ditch bearing platform; then, the closed area of the brick mold is filled with foam concrete in multiple layers; next, existing pipe ditch supporting piles are cut; the reserved holes of a bottom plate and the top plate are poured and plugged in time after pile cutting; and finally, foam concrete is filled in the rest unfilled area between the bottom of the pipe ditch bearing platform and the tunnel top plate in a layered mode; the existing pipe ditch bearing platform is monitored in real time in the construction period; and the monitoring work runs through the whole tunnel construction process. According to the method, the load of the pipe ditch bearing platform is effectively underpinned, so that the tunnel safely underpasses the lower pile foundation of the original pipe ditch bearing platform, and meanwhile, safe and stable operation of the pipe ditch is protected.
本发明公开了一种地道下穿混凝土管沟承台荷载托换保护施工工法，属于建筑施工工程领域。主要步骤包括：在地道主体结构(除支撑桩预留孔洞)施工完成后，在地道顶板与管沟承台之间砌筑砖模，接着在砖模封闭区域内分多层填充泡沫混凝土，然后对现有管沟支撑桩进行截桩，截桩后及时对底板和顶板预留孔洞浇筑封堵，最后在管沟承台底与地道顶板之间的剩余未填充区域分层填充泡沫混凝土，施工期间对现有管沟承台进行实时监测，监测工作贯穿地道施工的全过程。该方法有效进行了管沟承台荷载的托换，使得地道安全下穿原有管沟承台下桩基的同时保护管沟安全稳定运行。
