Expressway protecting plate with wiring grooves

Abstract

The invention discloses an expressway protecting plate with wiring grooves. The expressway protecting plate comprises a protecting plate, the wiring grooves and groove covers, and is characterized in that the cross section of the protecting plate is W-shaped; the protecting plate is composed of a first arc plate, a second arc plate and a connecting plate; the cross sections of the wiring grooves are C-shaped; the wiring grooves are formed in the inner sides of the first arc plate and the second arc plate and fixedly connected with the first arc plate and the second arc plate through bolts and first nuts; one groove cover is clamped on each wiring groove, and is fixedly connected with the corresponding wiring groove through a bolt and a second nut; drainage holes are formed in the lower edges of the groove covers; fixed-connection through holes are formed in the middle of the first arc plate and the second arc plate in the length direction of the plate body at equal intervals; wiring groove through holes and groove cover through holes are formed in the middle of the wiring grooves and the groove covers in the length directions of groove bodies and cover bodies at the same equal intervals as that in the arc plates; mounting through holes are formed in the middle of the connecting plate in the length direction of the plate body at the intervals of the fixed columns of the protecting plate; the protecting plate and the groove covers are made of low-carbon steel; and the wiring grooves are made of glass fiber reinforced plastics.

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
