Description

TECHNICAL FIELD

[0001] The present application relates to the field of high and steep slope dangerous rock mass protection and treatment, and particularly relates to a high and steep slope dangerous rock mass comprehensive protection and treatment system and a construction method. BACKGROUND

[0002] In the field of high and steep slope dangerous rock mass protection and treatment, traditional protection measures often have certain limitations. For example, some methods may only be suitable for specific types of dangerous rock mass, lacking adaptability to different dangerous rock masses; or they cause significant damage to the environment during construction, which is not conducive to ecological protection; some methods may have deficiencies in stability and durability, and cannot effectively protect the safety of the slope for a long time.

[0003] With the acceleration of urbanization and the continuous expansion of infrastructure construction, the stability of high and steep slopes is increasingly prominent. These slopes are often prone to erosion and damage due to complex geological conditions, variable weather, and other factors, leading to the formation of dangerous rock masses. The existence of dangerous rock masses not only threatens people's life and property safety, but also has a serious impact on the surrounding environment.

[0004] Traditional slope protection measures, such as simple rock anchoring and concrete pouring, often cannot meet the complex needs of high and steep slopes. These methods may be effective in the short term, but over time, due to the lack of comprehensive consideration of the overall stability of the slope, the protection effect may decrease, and even more serious geological disasters may be triggered.

[0005] Therefore, there is an urgent need for a new high and steep slope dangerous rock mass comprehensive protection and treatment system that can adapt to different slope section surfaces, while having the advantages of structural stability, environmental friendliness, and high construction efficiency. This system should comprehensively consider factors such as slope stability, ecological protection, and rainwater management to provide a comprehensive and effective protection and treatment solution for high and steep slopes.
