Highway structure

Abstract

The invention discloses a highway structure, and belongs to the building field. The highway structure comprises a stand column, a baffle, a connecting column and an adjusting component. The baffle isconnected to the stand column. A cross section of the baffle is wave-shaped, and transition plates are formed at wave crest and wave trough places. The connecting column is installed between the standcolumn and the baffle. The connecting column is connected with the stand column through the adjusting component. The adjusting component can be extended or shortened, so that a distance between the connecting column and the stand column is adjusted. The provided highway structure is capable of absorbing impacting kinetic energy in a certain degree.

Description

technical field [0001] The invention relates to the construction field, in particular to a highway structure. Background technique [0002] The emergency lanes are mainly designated on both sides of the urban ring road, expressway and expressway, and are specially used for vehicles dealing with emergency affairs such as engineering rescue, fire rescue, medical rescue or police performing emergency official duties. reason to stay in the driveway. However, due to the congestion of domestic expressway structures, drivers have insufficient understanding of the importance of emergency lanes, and the supervision of emergency lanes by relevant departments is also slightly insufficient, resulting in the emergency lanes of domestic expressway structures being often occupied and unable to operate. to its intended role. [0003] On both sides and in the middle of the expressway, expressway guardrails are designed and installed in order to prevent running vehicles from rushing out of ...

AI Technical Summary

Problems solved by technology

From the perspective of structure and safety performance, the existing highway guardrails mainly have the following defects: although the wall structure of the concrete guardrail can basically prevent large and heavy vehicles from going over the guardrail, and can effectively prevent small vehicles from getting out of the guardrail, but due to The concrete deforms very little when it is subjected to external loads, so the kinetic energy of the vehicle absorbed by the guardrail during the collision is very small, and the dynamic shear force on the collision vehicle is very large, which can easily cause serious damage to the vehicle, and even cause casualties to the occupants in the vehicle ; Although the semi-rigid wave guardrail has good comprehensive mechanical properties and has a good resistance and guiding effect on general vehicle collision accidents, the strength of the wave guardrail is not large enough to effectively intercept high-speed vehicles with high mass; the flexible cable guardrail is due to During the collision process, the contact area with the vehicle is small, the absorbed energy is limited, and it only has a good interception and guiding effect on the collision of the car
