Safety protective fence with warning function for expressway

Abstract

A provided safety protective fence with a warning function for an expressway comprises a supporting frame, a pressure relief device, a planting device, a filtering device, a supporting plate and a base, the pressure relief device is arranged in the right side of the supporting frame, the planting device is arranged at the top of the supporting frame, the filtering device is fixedly connected to the inner wall of the planting device, and the bottom of the supporting frame is fixedly connected with the upper surface of the supporting plate. Buffering and pressure relief are conducted on a vehicle through the pressure relief device, meanwhile, a warning strip is matched for use, a driver is warned conveniently, the driving safety performance is improved, landscape seedlings are planted through the planting device, fatigue of the driver is relieved, meanwhile, the effect of cleaning air is achieved, and the filtering device can effectively prevent debris such as silt from blocking a drainage pipeline. The safety protective fence is scientific and reasonable in structural design, high in practicability, low in manufacturing cost, good in using effect and capable of being used and popularized.

Description

technical field [0001] The invention belongs to the technical field of road safety protection, and in particular relates to a safety protection fence with a warning function for expressways. Background technique [0002] With the rapid development of traffic, expressway has brought great convenience to people's life, allowing vehicles to drive at high speed on it, which is convenient for people to drive. However, the accident rate of expressway is very high, and many vehicles are driving at high speed. Sometimes there will be a traffic accident, and once such a traffic accident occurs, it will often endanger the life of the driver. [0003] When a vehicle has an accident, it will mostly collide with the guardrail of the expressway. Crashing into the guardrail can reduce the accident rate. However, in the traditional highway crash barriers, some of the guardrails are simple in design and have no buffer protection device. The protective effect of vehicle collision If it is no...

[0002] With the rapid development of traffic, expressway has brought great convenience to people's life, allowing vehicles to drive at high speed on it, which is convenient for people to drive. However, the accident rate of expressway is very high, and many vehicles are driving at high speed. There will be traffic accidents, once such a traffic accident occurs, it will often endanger the life of the driver.

[0003] When a vehicle has an accident, it will mostly collide with the guardrail of the expressway. Crashing into the guardrail can reduce the accident rate. However, in the traditional highway crash barriers, some of the guardrails are simple in design and have no buffer protection device. The protective effect of vehicle collision If it is not good, it will cause damage to the vehicle, and the warning performance to people is poor. When planting landscape seedlings on the top of the guardrail, it is easy to cause blockage of drainage pipes, low rainwater utilization efficiency, and low efficiency of installation space utilization on viaducts.

[0004] In the prior art, most safety fences include guardrails and uprights for installing the guardrails. In order to ensure the strength of the uprights themselves, the bottom of the uprights needs to be deeply buried in the cement concrete base. If the uprights are a whole, the upper part of the uprights is damaged, and the It is difficult to take out the lower part for replacement. At this time, it is necessary to rebuild the cement concrete base, which consumes manpower, material resources and financial resources. If the column is two sections of movable connection, it is difficult to guarantee its own strength in use
