Ecological shed-tunnel structure for protecting a highway under a high and steep slope

Abstract

The invention discloses an ecological shed-tunnel structure for protecting a highway under a high and steep slope, and belongs to the technical field of highway protection. The ecological shed tunnelstructure comprises a support system at the lower part of the shed tunnel structure and an upper protective system, wherein the support system comprises a retaining wall, a column, a top plate, a cross beam and a longitudinal beam- The buffer layer in the protection system of the invention is small in quality, good in buffer effect and low in engineering cost of the ecological shed-tunnel structure. The supporting system adopts concrete pouring, and the anchor rod extends into the retaining wall, which effectively ensures the strength of the supporting system, and makes the ecological shed tunnel structure have good overall stability, and can effectively cope with the impact of rolling stone and debris flow, and has a higher safety factor; Components and materials can be purchased directlyin the market, site installation can be, construction is convenient, easy to maintain.

Description

technical field [0001] The invention relates to an ecological shed structure for protecting roads under high and steep slopes, and belongs to the technical field of road protection. Background technique [0002] In order to avoid damage to the road caused by rolling stones on high and steep slopes, and to ensure the safety of passing vehicles and personnel, steel protective nets are usually set up on the slopes. The protective effect of steel fence is limited. Secondly, there is also a method of building sheds above the road to protect passing vehicles and pedestrians. Sheds are divided into rigid sheds and flexible sheds according to their structure types. This reduces the engineering cost, but it only plays a protective role against the impact of rolling stones. For slopes with debris flow, the effect of flexible sheds is limited. At present, the most widely used is the rigid shed, that is, the reinforced concrete shed, which mainly relies on the soil and gravel buffer l...

AI Technical Summary

Problems solved by technology

According to the principles of physics and the rock rolling simulation software of the slope, in order to effectively reduce the impact of rolling rocks on the top of the shed, the thickness of the buffer layer is about 1.5 meters. The buffer layer is heavy and the buffering effect is poor. High requirements lead to high cost of shed tunnel project
