Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically a safety protection device for high slopes. Background Technology

[0002] High slope safety protection devices are safety equipment specifically designed to protect steep slopes (such as those along mountain roads, railway lines, and construction sites) from damage to people and facilities caused by natural disasters such as rockfalls, landslides, or mudslides. These devices can effectively improve slope stability, reduce the risk of geological disasters, and, to a certain extent, ensure the safety of pedestrians and vehicles.

[0003] Currently, safety protection devices for high slopes include protective nets, protective piles, or protective walls, with protective nets being the most widely used. Protective nets are generally laid on the surface of the slope to prevent soil and rocks from sliding down. However, during the protection process, as rocks and soil continue to fall off, the downward pressure on the protective net increases. Generally, for existing protective nets, due to gravity, the falling rocks and soil tend to concentrate on the lower side of the net. As the weight increases, the net is prone to tearing and losing its protective function.

[0004] Therefore, in view of the above-mentioned problems, this technical solution designs a high slope safety protection device. Utility Model Content

[0005] The purpose of this invention is to provide a safety protection device for high slopes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The high slope safety protection device includes a protective net laid on the slope surface. Symmetrical end plates are installed at the bottom of the net, with the bottom of the end plates installed on the slope. The top of the net is open to collect and block rocks and soil sliding down the slope. Multiple V-shaped grooves are evenly spaced along the slope's inclination direction on the net surface. These grooves are formed by pulling the inner side of the net in a direction perpendicular to the slope's slope (tension indentation). A filter row is connected between the inner side of the V-shaped groove and the slope's slope. The filter row applies tension to the net to form the V-shaped grooves. The filter row includes an upper top plate connected to the inner wall of the net at the inner side of the V-shaped groove. The bottom plate is connected by multiple equally spaced positioning posts. The bottom plate is fixedly installed on the slope. The intervals between adjacent positioning posts form a sliding channel. The sliding channels in all the filter rows distributed from top to bottom along the slope are set in a distribution pattern with progressively decreasing width, so as to classify and filter and block rocks and soil of different sizes. This disperses and blocks rocks and soil to a certain extent. Compared with concentrating them in one place inside the protective net, it can effectively improve the protection strength and reduce the blocking and breakage of the protective net. The V-shaped groove is used to form multiple areas of the protective net, which fully limits the rocks and soil inside the protective net.

[0008] As a further embodiment of this utility model: a set of U-shaped fixing frames is installed at the top of the protective net, and the bottom of the fixing frames is fixed to the slope.

[0009] As a further embodiment of this utility model: a fixing block is installed at the bottom of the fixing frame, and an installation plate is installed at the bottom of the end plate. Multiple installation holes are evenly opened on the fixing block, the installation plate, and the bottom plate. Anchor plates are set on the slopes corresponding to the bottom of the installation plate, the bottom plate, and the fixing block. The anchor plates are set in the concrete poured on the slope.

[0010] As a further embodiment of this utility model: the protective net is made of steel wire rope, galvanized steel strip, nylon rope or polyester rope, and the end plate and positioning post are made of stainless steel.

[0011] As a further improvement of this utility model, adjacent protective nets are connected in a contact-type distribution.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by laying the protective net on the slope, forming multiple areas under the pull of the V-shaped groove, and cooperating with the filter row on the lower side of each V-shaped groove to classify and block rocks and soil, the impact force of falling rocks or landslides is evenly dispersed, avoiding excessive local stress that could lead to overall failure.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 A high slope safety protection device includes a protective net 12 laid on the surface of a slope 11. End plates 13 are symmetrically installed at the bottom of the protective net 12, and the bottom of the end plates 13 are installed on the slope 11. The top of the protective net 12 is open to collect and block rocks and soil sliding down the slope 11. Multiple V-shaped grooves 18 are evenly spaced along the slope 11's inclination direction on the surface of the protective net 12. The V-shaped grooves 18 are formed by pulling (stretching) the inner side of the protective net 12 towards a direction perpendicular to the slope 11. A filter row is connected between the inner side of the V-shaped grooves 18 and the slope 11's inclination. The filter row applies tensile force to the protective net 12 to form the V-shaped grooves 18. The filter row includes components connected to the inner side of the protective net 12 within the V-shaped grooves 18. The upper top plate on the wall is connected to the lower bottom plate by multiple equally spaced positioning columns 15. The lower bottom plate is fixedly installed on the slope 11. The interval between adjacent positioning columns 15 forms a sliding channel 17. The sliding channels 17 in all the filter rows distributed from top to bottom along the slope 11 are set in a distribution pattern with progressively decreasing width, so as to classify and filter and block rocks and soil of different sizes that slide down. This disperses and blocks rocks and soil to a certain extent. Compared with concentrating them in a certain place inside the protective net 12, it can effectively improve the protection strength and reduce the blocking and breakage of the protective net 12. The V-shaped groove 18 is used to form multiple areas of the protective net 12, which fully limits the rocks and soil inside the protective net 12.

[0024] In this embodiment of the invention, a set of U-shaped fixing frames are installed at the top of the protective net 12. The bottom of the fixing frames is fixed to the slope 11 to maintain the stability of the protective net 12. At the same time, the opening at the top of the protective net 12 is used to transfer the sliding rocks and soil into the protective net 12, and then they are classified, retained and blocked by a multi-stage filter.

[0025] A fixing block is installed at the bottom of the fixing frame, and an installation plate 14 is installed at the bottom of the end plate 13. Multiple installation holes 16 are evenly opened on the fixing block, the installation plate 14, and the bottom plate. Anchor plates are set on the slope 11 corresponding to the bottom of the installation plate 14, the bottom plate, and the fixing block. The anchor plates are set in the concrete poured on the slope 11. The fixing plate, the installation plate 14, and the bottom plate are fixed on the anchor plates with bolts using the installation holes 16 on the fixing plate, the installation plate 14, and the bottom plate, thereby fixing the protective net 12.

[0026] In one embodiment of the present invention, the protective net 12 is made of steel wire rope, galvanized steel strip, nylon rope or polyester rope, etc. Steel wire rope and galvanized steel strip have the characteristics of high strength, impact resistance and corrosion resistance, while nylon rope or polyester rope has impact resistance, light weight and good elasticity.

[0027] The end plate 13 and positioning post 15 are made of stainless steel, which ensures that they can withstand the impact of rocks and soil and have sufficient corrosion resistance.

[0028] In a preferred embodiment of the present invention, adjacent protective nets 12 are connected in a contact manner to ensure that the surface of the slope 11 is covered and protected. At the same time, the end plate 13 is set at the bottom of the protective net 12 to fix the protective net 12 to the slope 11, while also effectively preventing rocks and soil that have slid down to the bottom of the protective net 12 from spreading further onto the road.

[0029] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
