Description
Technical Field
The invention relates to a technology for fusing a concrete guardrail and a sound barrier on the road side, in particular to a comprehensive road side safety and noise protection system which is beneficial to preventing out-of-road collision of out-of-control vehicles, providing good guidance for the out-of-control vehicles, preventing the out-of-control vehicles from being stumbled, reducing casualty degree of traffic accidents, blocking transmission of traffic noise on roads and reducing sound environmental pollution of roadside residential areas.
Background
Road routes often appear to cross or border populated areas subject to various conditions. In a road section with a residential area on the road side, the problems of safety protection and noise pollution reduction are generally solved by adopting a mode of arranging a rigid concrete anti-collision guardrail with high protection grade and a sound barrier. Rigid concrete anticollision barrier mainly used prevents that the vehicle out of control from rushing out outside the way to carrying out good direction in order to reduce vehicle collision barrier itself and causing passenger's risk to the vehicle, the sound barrier is then the traffic noise propagation on the mainly used separation highway, in order to reduce the sound environmental pollution degree of traffic noise to the roadside residential block. The inventor notices that at present, the concrete guard rail and the sound barrier belong to independent consideration and separate design, and the problem that the concrete guard rail and the sound barrier have influence on functions mutually is caused and mainly reflected in that: on one hand, the current sound barrier structure is formed by assembling steel upright posts and sound boards, is arranged at the top of a concrete guardrail, has the height generally more than 3 meters, and has smaller distance with the collision-facing surface of the concrete guardrail after installation; in the current state of the art, the steel pillar has a high rigidity, but the rigidity and strength of the sound plate material between the pillars are low, and the sound plate material is easily deformed, damaged, or detached during a vehicle collision. Due to the fact that the large-sized vehicle has large collision energy and large vehicle side inclination during collision, the existing arrangement structure with the sound barrier simply installed on the top of the guardrail is difficult to exert good collision prevention and guiding effects on the collided vehicle. Therefore, the installation of the sound barrier on the top of the concrete guardrail in the prior art is equivalent to the arrangement of a dangerous structure in the guardrail range, so that serious tripping can easily occur at the steel upright post of the sound barrier when a vehicle is out of control and collides, the anti-collision safety performance of the concrete guardrail is reduced, and even serious injuries and deaths of passengers in the vehicle are caused. Such traffic accidents also sometimes occur. On the other hand, if the influence of the sound barrier on the safety performance of the guardrail is to be avoided, the most typical method at present is to arrange the sound barrier away from the concrete guardrail, but the arrangement method is difficult to implement under the condition that the road side space of the road is limited at present in China, the noise reduction effect of the sound barrier is greatly reduced after the sound barrier is away from the guardrail (equivalently, the sound barrier is far away from a noise source), if the noise reduction effect is to be ensured, the arrangement height of the sound barrier needs to be increased, and the construction cost is necessarily greatly increased. Therefore, it is necessary to provide a more advanced technical apparatus to solve the safety protection problem caused by the current sound barrier configuration. Aiming at the problems, the inventor provides a highway binary protection system integrating an anti-collision function and a noise reduction function, so as to solve the problem of safety protection caused by the conventional common sound barrier setting and improve the highway safety and environmental protection level.
