Pipeline groove reverse slope excavation supporting device and construction method thereof
The invention discloses a supporting device for reverse slope excavation of a pipeline groove. The supporting device comprises a hydraulic system, a movable and slidable support assembly, an adjustable supporting assembly, a nested inclined column, a stand column and a side wall baffle. The nested batter post comprises an upper batter post, a relay batter post and a bottom batter post which are nested step by step and slide relatively; the hydraulic system comprises a large-tonnage hydraulic oil cylinder and a large-stroke hydraulic oil cylinder; by means of a telescopic structure formed by mutual nesting of the upper batter post, the relay batter post and the bottom batter post, supporting in different supporting structure depth ranges is facilitated, the problems of height limiting and width limiting in equipment transportation are solved, the adjustment time needed by an operator is shortened, the working efficiency is improved, reverse slope supporting and excavation are also facilitated, and the working efficiency is improved. Therefore, the construction earth excavation and backfill amount, the road recovery workload and the operation floor area are obviously reduced, and the problems that the floor area of trench excavation is large, the road occupation pressure is large, the supporting time is long, and the backfill soil quality cannot be guaranteed are effectively solved.
本发明公开了一种管道沟槽反坡开挖支护装置，包括液压系统、可移动与滑动的支座组件、可调节的支撑组件、嵌套式斜柱、立柱、侧壁挡板；所述嵌套式斜柱包括逐级嵌套且相对滑动的上部斜柱、中继斜柱、底部斜柱；所述液压系统包括大吨位液压油缸和大行程液压油缸；通过所述上部斜柱、中继斜柱和底部斜柱的相互嵌套的可伸缩结构，便于不同支护结构深度范围内进行支护，这也避免设备运输限高和限宽问题、减少了操作员所需要调整时间和提高了工作效率，也便于反坡支护和开挖，意味着施工土方开挖、回填量、道路恢复工作量和作业占地面积显著减少，有效解决沟槽开挖占地面积大、道路占用压力大、支护时间长、回填土质量无法保证等诸多问题。
