Side slope rolling stone rapid discharging structure used for protecting mountain highway

Abstract

The invention provides a side slope rolling stone rapid discharging structure used for protecting a mountain highway. The side slope rolling stone rapid discharging structure is characterized by being composed of a stone guide ladder, a stone guide net and a supporting frame, wherein the appearance of the stone guide ladder is in a downwards-bent arc shape; the inner end of the arc shape is the highest and the height of the outer end of the arc shape is higher than the lowest point of the arc shape; a stone guide groove matched with the walking direction of the stone guide ladder is formed in the upper side face of the stone guide ladder; the stone guide ladder spans across the upper side of the mountain highway; the inner end of the stone guide ladder is connected with the upper end edge of an inner side edge slope of the mountain highway; the outer end of the stone guide ladder extends to the outer side of the mountain highway; the upper end of the supporting frame is connected with the lower part of the stone guide ladder; the lower end of the supporting frame is connected with roadbeds on the two sides of the mountain highway; the stone guide net is arranged at the periphery of a rolling stone hidden danger region of the side slope and is distributed in a funnel shape; a notch is formed in the bottom of the funnel and is communicated with the stone guide groove. The side slope rolling stone rapid discharging structure has the beneficial effects that the protection effect of rolling stone disasters can be remarkably improved and rolling stones are prevented from being accumulated on a protection structure.

Description

Technical field [0001] The invention relates to a technology for the treatment of rock rolling disasters on mountain roads, in particular to a side slope rock rolling speed discharging structure used for mountain road protection. Background technique [0002] As an important part of China’s highway network, mountain roads have played an important role in promoting mountain resource development and improving mountain travel conditions. In recent years, mountain roads have experienced frequent geological disasters, seriously threatening traffic safety. It is especially worth noting that rolling stones have One of the three major geological disasters in mountainous areas. Its distribution range is extremely wide and its sudden frequency is high. It has caused great safety hazards to various structures and human activities within its hazard range. It has become a disaster after landslides, collapses, and mudslides. Another major geological disaster. [0003] The so-called rolling ...

AI Technical Summary

Problems solved by technology

[0004] At present, there are two main technologies related to the protection and management of rolling stone disasters on mountain slopes. One is active protection, such as clearing dangerous rocks, anchoring, supporting, inlaying, active mesh reinforcement, etc.; the other is passive protection, such as passive mesh reinforcement. , rockfall troughs and shed caves, etc.; generally speaking, rolling rocks mainly originate in steep alpine valleys, and it is very difficult to implement active protection. In actual projects, passive protection measures are often used to protect rolling stone disasters. The structure is one of the more effective protection projects; however, the shed cave mainly uses the sand and gravel cushion on the top of the structure to dissipate energy to resist the impact of rolling stones. Due to the impact of rolling stones, the structure has a short life span and requires regular maintenance, and rolling stones and crushed stones Chips are easy to accumulate on the roof of the shed. In actual situations, it is difficult to quickly remove the rolling stones deposited on the roof of the shed, causing the structure of the shed to bear a large load for a long time, which further affects the life of the structure.
