A rapid reinforcement device for slope protection of river dam subgrade

Abstract

A rapid reinforcement device for slope protection of a river dam subgrade, including a slope and a metal mesh covered on the slope surface. The metal mesh is fixed on the slope surface by several uniformly distributed fixing devices. The fixing device includes a pressing plate, and the left slope of the pressing plate is It is in contact with the right side of the metal mesh, and the left side wall of the pressure plate is fixedly connected with a cylinder with an opening on the right side. The middle part of the left side wall of the cylinder and the middle part of the plate surface of the pressure plate are both provided with a first passage on the same horizontal line. The two first through holes are connected with the same horizontal externally threaded pipe through sealed bearings, and the right end of the externally threaded pipe is fixedly connected with a bolt head. The invention has compact structure and reasonable design, and the metal mesh is pressed tightly on the slope by multiple fixing devices, making it difficult to slide, and the pressing plate of the fixing device plays a role in making the metal mesh fit the slope, so that the metal mesh is not easy to warp The bending deformation makes the tarpaulin compacted by the pressing block, and the gap between the tarpaulin, the pressing plate and the slope will not be too large, so that the rainwater is not easy to wash the slope protection.

Description

technical field [0001] The invention belongs to the field of slope protection and reinforcement devices, in particular to a rapid reinforcement device for slope protection of river dam subgrades. Background technique [0002] When the rainy weather comes and it is necessary to quickly reinforce the slope protection, metal mesh is often used to cover the slope protection, and then the metal mesh is fixed by driving multiple U-shaped pins into the soil. Finally, after the rainy day is over, according to the needs Spray or pour the slope protection, and at the same time cover the slope with tarpaulin to prevent the erosion of rainwater, but the fixing effect of the U-shaped pin is poor, and the metal mesh cannot be attached to the slope, especially in rainy weather and other weather conditions The slope protection is easy to slide under the erosion of rainwater, and most of the current rainproof tarpaulins are pressed by stones. In rainy days, it is usually accompanied by stron...

Finally, after the rainy day is over, according to the needs Spray or pour the slope protection, and at the same time cover the slope with tarpaulin to prevent the erosion of rainwater, but the fixing effect of the U-shaped pin is poor, and the metal mesh cannot be attached to the slope, especially in rainy weather and other weather conditions The slope protection is easy to slide under the erosion of rainwater, and most of the current rainproof tarpaulins are pressed by stones. In rainy days, it is usually accompanied by strong winds. The cloth is scraped away, causing damage to the slope protection
