Embodiment Construction

[0022] figure 1 It shows that in areas prone to rolling stone disasters, a C15 flake concrete rock wall 1 is set at a suitable position inside the infrastructure (road, railway, house, etc.); a prestressed anchor cable 2 is set in the rock wall; Pre-buried steel rail fence 3; a double-layer buffer cushion layer structure is set on the back side of the stone barrier wall (ie, the reverse slope surface): the inner layer is a foam plastic layer 4, and the outer layer is a sand and gravel filling layer 5. There is a pre-embedded polyvinyl chloride pipe 6 inside the flake concrete retaining stone wall 1; the prestressed anchor cable 2 is arranged in the pre-embedded polyvinyl chloride pipe. The anchor head 2a is set on the top of the polyvinyl chloride pipe. The cross-section of the flake concrete retaining stone wall 1 is a right-angled trapezoid, the facing slope of the stone retaining wall is a vertical surface, and the facing slope of the sand and gravel fill layer is a slope....

Abstract

The invention relates to a novel energy consumption damping stone blocking structure which belongs to structures for preventing and controlling stone rolling disasters. The structure comprises a stone blocking wall which is a flag concrete stone blocking wall; the top of the stone blocking wall is preembedded with a steel rail fence; a prestress anchor cable is arranged in the stone blocking wall, and the front slope surface of the stone blocking wall is sequentially provided with a foam plastic layer and a gravel filling layer which are arranged for playing the buffering function. The invention has the characteristics of light weight, economy, safety and simple construction.

Description

technical field [0001] The invention relates to geological disaster prevention and control technology, and is an economical and effective new protection structure which is especially suitable for the anti-rolling stone impact of the rolling stone disaster prevention structure. Background technique [0002] Rolling stones can be seen everywhere in the mountainous areas of our country, especially along the highways in the western mountainous areas. Caves, sheds, etc.; human activities such as: driving vehicles, passing crowds, etc. constitute a serious threat, and have become another major geological disaster after landslides, collapses, and mudslides. [0003] In general, the prevention and control methods of rolling stone disasters can be divided into two categories: active protection and passive protection. Active protection aims to take measures to prevent the instability of potential rolling rocks, while passive protection refers to allowing rolling rocks to occur but av...
