An anti-collision fence for expressway

Abstract

The invention relates to the field of expressway guardrail, in particular to an expressway guardrail, comprising a pressure relief structure, a support frame, a planting structure, a filtering structure, a muffler board, a warning strip, a support board and an installation structure. The bottom end of the support plate for mounting the limited rectangular structure is provided with a mounting structure for mounting on the viaduct for reinforcement. The top end of the support plate is provided with a support frame of a rectangular frame structure for supporting the planting structure, and the inside of the planting structure for planting seedlings is provided with a filtration structure for preventing blockage. The side wall of the support frame is provided with a pressure relief structurefor pressure relief and collision avoidance, and the pressure relief structure is alternately provided with a muffler board for muffling noise and a warning bar for warning. The use of the pressure relief structure of the invention improves the cushioning and pressure relief function to the vehicle, when the vehicle collides on the pressure relief structure, the vehicle collision force is counteracted, the vehicle is prevented from being damaged in the collision process, and at the same time, the use of the warning strip is convenient for early warning to the driver, and the driving safety performance is improved.

Description

technical field [0001] The invention relates to the field of expressway guardrails, in particular to an expressway anti-collision guardrail. Background technique [0002] With the rapid development of society and the rapid development of traffic, highways have brought convenience to people's travel. Highway guardrails are the main form of semi-rigid guardrails. The continuous structure of the support plays a very good role in protecting the vehicle and the drivers and passengers, and improves the safety of people's travel. [0003] However, the traditional highway anti-collision guardrail is easy to cause vehicle damage when it collides with vehicles during use, and has poor warning performance for people. When planting landscape seedlings on the top of the guardrail, it is easy to cause drainage pipe blockage and low rainwater utilization efficiency. The space utilization efficiency is low. In view of this, the present invention provides a highway crash barrier, which has...
