Description

Technical Field

[0001] The utility model belongs to the technical field of slope protection, and in particular relates to a slope protection device for water conservancy and hydropower engineering. Background Art

[0002] Water conservancy and hydropower engineering refers to various projects for the purpose of flood control, irrigation, power generation, water supply, waterlogging control, water environment management, etc. In the field of water conservancy and hydropower engineering, protective devices are needed to support and protect the slopes of water conservancy and hydropower engineering. At present, protective nets are commonly used to protect the slopes. For example, the Chinese patent document with announcement number CN217896399U discloses a protective device for slopes of water conservancy and hydropower engineering. The utility model is provided with a fixing mechanism above the counterweight block. By using the mutual cooperation of the fixing mechanism, the bottom of the laid protective net can be conveniently fixed, making the laying of the protective net more convenient and efficient, thereby greatly improving the convenience of the device when in use. The use of protective nets in the above scheme can reinforce the slopes, but it cannot protect against falling rocks. When dangerous rocks fall, they will directly roll through the slopes to the road surface at the bottom of the slope, posing a serious safety hazard to passing vehicles. At the same time, existing water conservancy and hydropower slope protection net devices generally use an integral large-area steel wire protective net. Since this type of protective net is an integral whole, it needs to be replaced as a whole to repair it after it is damaged at a certain position, which is costly and easy to cause waste.
