Side ditch structure with guard, member and highway containing side ditch structure

Abstract

The invention provides a side ditch structure with a guard, a member and a highway containing the side ditch structure, and relates to the technical field of highway engineering. The side ditch structure with the guard comprises a side ditch body, a first ditch is arranged in the side ditch body, a non-porous ditch cover sealing the upper part of the first ditch is arranged at the top of the sideditch body, a guard plate is arranged on the left side of the non-porous ditch cover and located above the side ditch body, the bottom end of the guard plate is connected with the top end of the leftside wall of the side ditch body, and a water inlet hole for water on the left side of the guard plate to flow into the first ditch is formed in the left side wall of the side ditch body and / or the guard plate. For the highway provided with the side ditch structure, a guardrail is not needed to be mounted on the outer side of the shoulder, and accumulated water on the road surface can also be drained away in time effectively; under the condition of the same effective width of the road surface, the highway provided with the side ditch structure has the advantages that less mountain is dug, andengineering cost is lower; compared with the same rock digging amount in the traditional mode, larger effective road width can be obtained by the highway provided with the side ditch structure.

Description

technical field [0001] The invention relates to the technical field of highway engineering, in particular to a side ditch structure and components with guards and a road including the side ditch structure. Background technique [0002] Most of the construction methods (traditional methods) of roadside ditches on existing expressways are as follows: figure 1 and figure 2 As shown, the side ditch is designed on the outside of the shoulder of the emergency lane. In order to prevent vehicles from accidentally driving into the side ditch and colliding with the roadside slope protection 11, a guardrail 12 is usually installed between the side ditch and the emergency lane. On the outside, in order to reduce the falling soil and rocks from slope protection into the side ditch, such as figure 1 and figure 2 As shown, usually also will stay a small platform between side ditch and slope protection 11. There are following problems in this design: 1. The position where the guardrai...

AI Technical Summary

Problems solved by technology

There are following problems in this design: 1. The position where the guardrail 12 is installed and the small platform left between the side ditch and the slope protection 11 all need to occupy a certain road width, which leads to a large excavation amount of the roadside mountain body and high engineering cost

2. Even if there is a small platform on the outside of the side ditch, the side ditch will often be silted up by rolling earth and rocks. Once the side ditch is silted up, the accumulated water on the road will not be drained away in time, which will bring safety hazards to driving

The high side ditch with guard structure also has the following problems in practical application: in order to prevent the vehicle from crashing directly into the baffle and slope protection in case of an accident and to reduce the degree of injury to the occupants in the event of an accidental collision, the It is usually necessary to install a guardrail between the ditch and the emergency lane (in order to ensure the stability of the guardrail installation, there must be a certain distance between the guardrail and the side ditch). Therefore, the role of the high-level side ditch with a retaining structure in reducing the amount of mountain excavation and reducing the cost of the project still needs to be further improved
