The embodiment of the invention provides a temporary support device for a roadway, which relates to the field of roadway construction technology. It consists of a top guard plate, a left guard plate and a right guard plate. The left guard plate and the right guard plate are located on the opposite sides of the top guard plate. A first driving unit is installed between the top guard plate and the left guard plate. A second driving unit is installed between the top guard plate and the right guard plate. Under the action of the first driving unit and the second driving unit, the top guard plate, the left guard plate and the right guard plate are located in the roadway. Surrounding rock joints. The temporary support device of the roadway provided by the invention enlarges the spacing between the top guard plate and the left guard plate and between the top guard plate and the right guard plate under the drive of the first driving unit and the second driving unit, thereby enabling the three guard plates to be joined separately in the surrounding rock of the roadway; compared with the traditional support device, besides the top guard plate which provides the support of the roof guard plate, there is also a left guard plate. The protective plate and the right side protective plate improve the safety of protection.

巷道临时支护装置
本专利技术实施例涉及巷道施工
,尤其涉及一种巷道临时支护装置。
技术介绍
为避免空顶作业,巷道掘进要求在断面形成后立即进行临时支护,避免碎矸掉落伤人。随着巷道支护难度的不断提高,近年来能对围岩施加主动支护力并抑制开挖初期围岩不连续有害变形的临时支护装置逐步得以发展。目前常见的临时支护方式为前探梁临时支护和迈步式临时支护支架:前者是在巷道断面形成后,人工将前探梁前移,对新开挖形成的裸露顶护板进行临时支护,机械化程度低,临时支护效果差,只能起到遮挡矸石掉落的作用,无法主动支护围岩;后者一般由一组支架由前后两架支架和连接支架的液压油缸组成,其工作过程为后架撑起,液压油缸伸长,推动前架前移,前架撑起,后架降下,液压油缸收缩,拖动后架前移,从而实现前、后两个支架的迈步式前进,在迈步前进的过程中需要反复支撑顶护板,极大地破坏了顶护板的完整性。另外,这两种常用的方式中都是仅有顶护板支护,承受的巷道围岩压力有限,容易出现片帮伤人事故,防护性较差。
