With the progress of society and the development of the economy, road traffic is becoming more and more developed and is still under continuous development. However, mountain roads have their own unique safety hazards. There are often slopes beside the roads. If no construction treatment is carried out, there will be very serious safety hazards. Therefore, generally, a protection device needs to be set between the road and the mountain to reduce the safety hazards of mountain roads.

[0003] The prior art patent number CN218373930U discloses a protection device for highway slope construction, including a connecting plate, fixing nails, a protection mechanism for blocking objects such as stones falling from the mountain or the road to prevent them from hitting workers, and also including a moving mechanism that allows workers to move safely on the connecting plate. The fixing nails are provided in multiple numbers and are arranged at the front and rear ends of the connecting plate; after the device is installed on the slope, through the protection frame, when workers are constructing the slope or mountain of the highway, they can well protect the workers so that the falling stones will not hit the workers. When workers are constructing the slope or mountain of the highway, if the slope is relatively large, they can install two load-bearing hooks on their bodies before construction, buckle the load-bearing buckle to the cable, and then buckle the other load-bearing buckle to a suitable hanging ring after moving to a suitable position, so that workers can construct on slopes and mountains with relatively large slopes and ensure the safety of workers.

[0004] However, the above-mentioned disclosed protection device has problems such as too high cost, complex device, and inability to make good use of the existing conditions of the on-site construction environment; at the same time, the above-mentioned disclosed protection device also does not consider the protection requirements for the damage of the road surface caused by slope falling stones.

[0006] The utility model provides a protection device for highway high slope repair and maintenance construction, which includes a support bottom column, a support upright column, an inclined support column and a transverse strengthening column. The support upright column is fixedly arranged on the support bottom column. The two ends of the inclined support column are respectively connected to the end of the support bottom column and the support upright column, so that the inclined support column is arranged obliquely. The transverse strengthening column is connected to the support upright column, and a protection net is connected between the support upright columns. It also includes an upper anchor rope and a lower anchor rope. One end of the upper anchor rope is connected to the support upright column, and one end of the lower anchor rope is connected to the support bottom column. The other ends of the upper anchor rope and the lower anchor rope are connected to the mountain body.

[0007] Preferably, a bamboo glue board is arranged at the front end of the support bottom column.
