Highway double-layer anti-collision guardrail with alarm function and its construction method

Abstract

The invention discloses an expressway double-layer anti-collision guardrail with an alarm function and a construction method thereof, wherein the guardrail comprises: uprights; connecting plates arranged between adjacent uprights; anti-collision layers consisting of a plurality of steel cables ; The alarm layer includes a remote alarm, a tough rope and a touch switch; the touch switch is embedded in the groove of the column; the two ends of the tough rope are respectively connected to the touch switch; the tough rope bends to pull the touch switch, so that The touch switch is disconnected to trigger the remote alarm to send an alarm; the buffer protection layer includes a protection pad and a barrier plate; a protrusion is provided on the surface of the protection pad facing the road; the raised part protrudes from the barrier plate through the through hole of the barrier plate surface. It can effectively reduce the impact force of the vehicle crashing into the guardrail, thereby reducing the impact damage to the vehicle and members of the accident; using the remote alarm setting, it improves the efficiency of relevant personnel to deal with the accident and reduces the impact of the accident on traffic. And it is convenient for the management of the anti-collision barrier.

Description

technical field [0001] The invention relates to the technical field of road facility construction, in particular to a double-layer anti-collision barrier for expressways with an alarm function and a construction method thereof. Background technique [0002] With the continuous development of economic construction, transportation is becoming increasingly busy. Traffic accidents are happening more and more frequently on highways or bridges. In order to reduce traffic accidents, various guardrails are installed on both sides of the road. The common guardrails are metal railings on the upper part of the concrete base or directly composed of iron railings on the metal bracket. The guardrails on the concrete base are used Concrete construction is required, which not only requires large-scale equipment for concrete pouring, but also requires maintenance after the construction of the guardrail before it can be used; while the construction of the guardrail directly composed of metal...

Problems solved by technology

In order to reduce traffic accidents, various guardrails are installed on both sides of the road. The common guardrails are metal railings on the upper part of the concrete base or directly composed of iron railings on the metal bracket. The guardrails on the concrete base are used Concrete construction is required, which not only requires large-scale equipment for concrete pouring, but also requires maintenance after the construction of the guardrail before it can be used; while the construction of the guardrail directly composed of metal brackets and horizontal railings is simple, but the protective effect is not good. It is easy to deform and break when an accident occurs, and the maintenance cost is high; at the same time, both the concrete base guardrail and the metal bracket guardrail are hard structures without elasticity. When the car collides with the guardrail, the momentary impact load Under the action of the collision, the energy generated during the collision is basically absorbed by the vehicle itself, so the damage to the vehicle and the occupants in the vehicle is very large.

[0003] In addition, the existing anti-collision barriers need to be found by the staff after the accident is damaged. After the accident, the accident personnel need to manually notify the relevant personnel, and then wait for the staff to arrive at the scene to deal with it before the road can be moved away. Especially on highways, this efficiency in dealing with accidents seriously affects traffic
