Description

A kind of shed cave type anti-slip structure with road system and construction method

technical field

The invention belongs to the technical field of road engineering, and in particular relates to a shed cave type anti-slip structure technology with a road system.

Background technique

In mountain road engineering design, landslides are often encountered due to the special terrain and geological environment. For landslides that are more harmful, avoidance measures are often adopted through the selection of plans. However, if the detour cost is too high after sufficient plan comparison and selection, it is advisable to consider rectifying the landslide. In the prior art, when constructing roads in landslide areas, landslides are generally treated first, and landslides are usually treated by measures such as removing landslide bodies, treating surface water and groundwater, reducing weight and back pressure, and setting up support structures. For large-scale landslides, the above-mentioned control measures require a large amount of construction and high cost, which are uneconomical and unreasonable. Therefore, there are roads that use anti-slide piles to treat landslides. For example, the patent with the application number of 201620242141.9 discloses a cantilever structure road combined with h-type anti-slide piles to treat landslides, which avoids high filling and deep excavation on the landslide body, and greatly reduces the amount of filling and excavation works. However, when the road and the anti-sliding piles are combined into a whole, when the road is subjected to the traffic load, the anti-sliding piles below will be disturbed, which will then affect the unstable soil layer on the landslide body, causing the sliding of the unstable soil layer. Such roads combined with anti-slide piles still have potential safety hazards. Moreover, the rolling stones on the landslide will also have a great impact on road traffic, endanger the safety of people, and cause economic losses.
