Highway ramp fork collision prevention device

Abstract

The invention discloses a highway ramp fork collision prevention device. The highway ramp fork collision prevention device comprises a collision prevention barrel and a collision prevention column; the collision prevention column is composed of an inner steel plate, an energy dissipation layer, a foam concrete structure layer and an outer steel plate; the inner steel plate is in a round tube shapeand is filled with foam concrete to form a foam concrete structural layer; the outer side of the steel plate is surrounded by the circle of energy dissipation layer; and the outer steel plate is a round tube, and the outer side surface of the energy dissipation layer is wrapped by the outer steel plate. The collision prevention barrel is a hollow cylinder, and the upper surface of the collision prevention barrel is provided with a hole for inserting the collision prevention column, and the edge of the upper surface of the collision prevention barrel is provided with a water injection port forinjecting liquid into the collision prevention barrel. The highway ramp fork collision prevention device has the advantages of reducing the damage to a highway when a vehicle hits, and also protecting a driver in the vehicle to a large extent to prevent secondary injury. The anti-corrosion durability is greatly improved after polyurea material is sprayed, and the ductility of the energy dissipation layer is improved as well. Processing is convenient, site construction is allowed, and thus the construction period is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of highway anti-collision, in particular to an anti-collision device for a road ramp switch. Background technique [0002] With the vigorous development of the transportation industry and economic construction, a large number of highways have been built and the number of vehicles has continued to increase, and due to various reasons for drivers, some drivers have a fluke mentality at the ramp due to inattention. And other factors, the accidents that the driver drives the vehicle to make a sharp turn at the ramp and cause the vehicle to hit the protective device of the ramp fork are also increasing. The vehicle impact protection device is not only easy to cause tragedies such as car crashes, but also reduces the bearing capacity and durability of the road structure to a certain extent during the design life period. The excessive movement of the protection device caused by the collision will directly affect th...

Problems solved by technology

However, there are the following problems when using commonly used plastic / glass fiber reinforced plastic anti-collision barrels: 1. It is easy to scratch the car when the car is slightly hit. And personnel, 3. Once the FRP anti-collision bucket is broken after being hit, it is easy to cause secondary damage to the vehicle and the driver. 4. The glass anti-collision bucket cannot be recycled, resulting in waste of resources and other shortcomings
