Highway guardrail with wiring grooves

Abstract

A highway guardrail with a wiring groove, including a guardrail, a wiring groove, and a groove cover. It is characterized in that: the cross section of the guardrail is "W" shaped, and the The connecting plate is composed of a "C"-shaped cross-section of the wiring groove, which is placed on the inner side of the first arc-shaped plate and the second arc-shaped plate, and is connected to the first arc-shaped plate and the second arc-shaped plate by bolts and first nuts. The arc-shaped plate is fixed, the groove cover is clamped on the wiring groove, and it is fixed with the wiring groove by bolts and second nuts. The lower edge of the groove cover is provided with drainage holes. The first arc-shaped plate and the second arc The middle of the shaped plate is provided with solid connection holes, wiring grooves, and slot covers at even intervals along the length direction of the plate body, and the middle of the slot body and the cover body are provided with wiring slot through holes and slot cover through holes at the same uniform intervals along the length direction of the slot body and cover body. The middle of the connecting plate is provided with installation through holes along the length direction of the plate body at intervals according to the guardrail fixing columns. The material of the guardrail plate and the groove cover is low carbon steel, and the material of the wiring groove is glass fiber reinforced plastic.

Description

technical field [0001] The invention relates to an expressway guardrail, in particular to an expressway guardrail with wiring grooves. Background technique [0002] The guardrail is a standard facility for highways. The guardrail is composed of a guardrail and a fixed column. The guardrail is installed on the fixed column. The current highway guardrail only has the function of blocking and buffering. When the guardrail is hit, it is absorbed by the deformation of the guardrail. Collision energy, reduce the possible damage to the car and human body caused by the accident, and reduce the degree of disaster of the accident; at the same time, it is often necessary to install some fixed or temporary equipment such as various warning devices, light signs, and surveillance cameras during the operation of the expressway , Lighting lamps, etc. The installation of these devices often requires the laying of power lines, signal lines, network cables and other lines at the same time.

[0002] The guardrail is a standard facility for highways. The guardrail is composed of a guardrail and a fixed column. The guardrail is installed on the fixed column. The current highway guardrail only has the function of blocking and buffering. When the guardrail is hit, it is absorbed by the deformation of the guardrail. Collision energy, reduce the possible damage to the car and human body caused by the accident, and reduce the degree of disaster of the accident; at the same time, it is often necessary to install some fixed or temporary equipment such as various warning devices, light signs, and surveillance cameras during the operation of the expressway , Lighting lamps, etc. The installation of these devices often requires the laying of power lines, signal lines, network cables and other lines at the same time. A large amount, and destroy the road surface, and even affect the traffic of the expressway; the expressway guardrail is everywhere along with the expressway, and the newly installed fixed or temporary equipment is often next to the guardrail. If the expressway guardrail can be used to lay out various This kind of line will greatly reduce the engineering quantity of trench excavation and reduce the engineering cost at the same time
