Maintenance structure and maintenance method for gravel bed tunnel
The invention discloses a gravel bed tunnel tunnel maintenance structure and a maintenance method thereof. The gravel bed tunnel tunnel maintenance structure comprises connecting pieces, stand columns arranged on the side walls of the two sides of a tunnel and arc-shaped supporting plates with arch feet erected on the stand columns and connected through the connecting pieces. The connecting piece comprises a first connecting plate and a second connecting plate which are arranged at the obtuse included angle between the arc-shaped supporting plate and the stand column, the first connecting plate is connected with the arc-shaped supporting plate in an attached mode, and the second connecting plate is connected with the first connecting plate and connected with the stand column in an attached mode. The connecting piece is arranged on the stand column to be connected with the arc-shaped supporting plate, the first connecting plate and the second connecting plate of the connecting piece are connected with the arc-shaped supporting plate and the stand column in an attached mode, force brought by external expansion of the arc-shaped supporting plate can be effectively blocked, and the connecting stability of the arc-shaped supporting plate and the stand column is enhanced; the hidden danger of safety supporting caused by infirm connection of the arc-shaped supporting plate and the stand column is avoided, and in addition, the risk of upwarp of the stand column can be avoided through the arrangement of the locking device.
本发明公开了一种砂砾层洞子渠隧洞维护结构及其维护方法，包括连接件、设置在隧洞两侧侧墙上的立柱以及拱脚搭设在立柱上并通过连接件连接的弧形支护板，连接件包括设置在弧形支护板与立柱钝角夹角处的第一连接板和第二连接板，所述第一连接板与所述弧形支护板贴合连接，所述第二连接板与所述第一连接板连接且与所述立柱贴合连接；本发明通过在立柱上设置连接件与弧形支护板完成连接，连接件的第一连接板和第二连接板分别与弧形支护板和立柱贴合连接，可以有效阻挡弧形支护板外扩带来的力并加强弧形支护板与立柱连接的稳定性，避免弧形支护板与立柱连接不牢固带来的安全支护隐患，此外，锁紧装置的设置可以避免立柱发生上翘的风险。
