Description

Roller device for traffic isolation guardrail and guardrail Technical Field The invention relates to the technical field of traffic guardrails, in particular to a modularized roller isolation guardrail, and particularly relates to a roller device for the traffic isolation guardrail and the guardrail. Background The traffic isolation guardrail is used as an important component of road infrastructure, and has the core functions of realizing physical isolation of traffic flows and people flows in different directions, guaranteeing traffic order and traffic safety, and simultaneously having a certain anti-collision buffer capacity when traffic accidents occur, so as to reduce casualties and property loss caused by the accidents. At present, the main stream traffic isolation guardrails on the market are mainly divided into two types, namely a precast concrete isolation belt which has stronger impact resistance stability by virtue of the characteristic of large self weight and can effectively prevent vehicles from crossing lines. On the one hand, the prefabricated concrete member has high weight and volume, high requirement on transportation equipment in the transportation process and high transportation cost, and needs large hoisting equipment to be matched during construction and installation, the construction process is complex, the flexibility is poor, the rapid pavement requirements of different road scenes are difficult to adapt to, on the other hand, the concrete member has high hardness and extremely poor toughness, the buffer unloading function is hardly provided when the vehicle is collided, the collision impact force can be directly transmitted to the vehicle and drivers, the vehicle is easily damaged seriously, meanwhile, the drivers and the drivers face huge impact injury risk, the concrete isolation belt is easy to crack after the collision, the repair difficulty is high, and the cost is high. The other type is a steel pipe type guardrail which is formed by splicing metal pipes, the weight is relatively light, and the convenience in transportation and construction is superior to that of a concrete isolation belt. However, the potential safety hazard of the steel pipe type guardrail is also prominent, the steel pipe is a rigid rod piece, the deformation amount is limited during collision, the buffering effect is poor, the end part of the steel pipe is sharp, the steel pipe is easy to penetrate through a vehicle body under a high-speed collision scene, fatal penetrating injury is caused to drivers and passengers, in addition, the steel pipe is likely to be broken and splashed in the collision process, and formed splashes can cause secondary injury to other vehicles and road pedestrians running around, so that the accident influence range is enlarged. Meanwhile, the existing two types of guardrails have the problem of single function, only the isolation and anti-collision functions of the foundation can be realized, and the expansion requirements of modern traffic on the guardrails in the aspects of traffic indication, information acquisition, risk early warning and the like cannot be met. And two kinds of guardrails are damaged, the maintenance mode is complex, the concrete isolation belt needs to be replaced integrally, the steel pipe type guardrails need to be cut, welded and repaired, the operation and maintenance efficiency is low, the cost is high, and the quick repair is difficult to realize so as to recover the road traffic capacity. Based on the defects of the prior art, a traffic isolation guardrail and a core component which have the advantages of convenience in transportation, flexibility in construction, anti-collision buffering safety and low operation and maintenance cost and can expand the function to adapt to modern traffic demands are needed. Disclosure of Invention In order to solve the problems of low construction flexibility, poor anti-collision buffer effect, easy penetration injury when traffic accidents happen to the existing steel pipe type guardrail, personal safety of drivers and passengers in a dangerous locomotive and the like in the conventional precast concrete isolation belt transportation, the application provides a combined type central guardrail, which at least solves one of the following technical problems: 1. The steel pipe type isolation belt solves the problems that an existing precast concrete guardrail is heavy and difficult to transport, unloading force and buffering effect are poor when a vehicle collides, 2, the problem that an existing steel pipe type isolation belt is easy to cause penetrating injury to vehicles and drivers and passengers when the vehicle collides, and meanwhile, other vehicles and traffic participants are easily injured when the steel pipe type isolation belt collides, 3, convenience in operation and maintenance and low-cost maintainability after the central guardrail is damaged are improved, 4, the problems of expanding functions of traff
