Deformation protection structure of underground pipeline and construction method
The invention discloses a deformation protection structure of an underground pipeline and a construction method, and aims to guarantee the safety of the buried underground pipeline under the conditions of ground overload and close soil disturbance, the protection structure comprises a small groove and a foundation cushion layer which are arranged at the bottom of a groove, a pipe seat pillow base is placed in the small groove, and a pipe seat is placed in the pipe seat pillow base. An underground pipeline is placed on the pipe seat pillow base, supporting retaining walls are arranged above the foundation cushion layer, the supporting retaining walls on the two sides and the foundation cushion layer form a cavity, foamed cement light soil is cast into the cavity in a cast-in-place mode to package the pipeline, geotechnical bags are fully laid between the supporting retaining walls and the groove side slope, and the structure further comprises a bearing top plate arranged above the supporting retaining walls in a covering mode. The protection system is mainly used for solving the problem that in the existing urban road construction process, nearby pipelines are deformed and damaged and are difficult to protect, effective deformation control and protection can be conducted on the nearby pipelines in road construction, and the protection system and a pipeline structure are the same in service life, construction is convenient and rapid, and certain waterproof and damping protection effects are achieved.
本发明公开了一种地下管线的变形保护结构及施工方法，目的是保证所埋地下管线在受到地面超载和临近土体扰动情况下的安全性，保护结构包括设置在沟槽底部的小凹槽和基础垫层，小凹槽内安放有管座枕基，管座枕基上安放地下管线，基础垫层上方设有支撑挡墙，两侧的支撑挡墙与基础垫层形成了空腔，将泡沫水泥轻质土现浇入上述空腔中包封管线，支撑挡墙与沟槽边坡间设有铺满的土工袋，还包括盖在支撑挡墙上方的承载顶板。本发明主要用于解决现有城市道路施工过程中附近管线发生变形破坏而难以保护的问题，可对道路施工附近的管线进行有效的变形控制和保护，该保护体系与管线结构寿命相同，施工方便快速，并且兼具一定的防水、减震保护作用。
