Description
Technical Field
The utility model belongs to the traffic field of sound barrier and safety protection combination, and particularly relates to a guidable anti-collision sound barrier structure.
Background
In order to promote national economic development and facilitate people's transportation and travel, the road traffic construction of China is always in a high-speed development situation, when designing a road route, in the face of continuously increased vehicle-passing mileage and a relatively limited construction space, more and more road sections of roads passing through or near residential areas are provided, along with the continuous improvement of road network grades and traffic conditions, the vehicle speed is higher and higher, the vehicle flow is larger and higher, and the traffic noise radiated on the two sides of the roads is stronger and higher. According to the national environmental monitoring result, about 17% of cities in road traffic noise belong to moderate pollution, 49% of cities belong to light pollution, and the city pollution brings lasting adverse effects to the life and work of people, thus becoming a prominent environmental problem.
The sound barrier is used as a simple, effective and economic noise reduction measure, is arranged between a noise source and a sound receiving point, and enables sound wave propagation to have obvious additional attenuation through a sound absorption material, a sound insulation material or a sound absorption and sound insulation mixed material, thereby weakening the noise influence in a certain area where a receiver is positioned. It is also proposed in the road environmental protection design Specification (JTG B04-2010) that a road project deals with the pollution of traffic noise to the sound environment, and when the road is close to environmental sensitive points such as schools, hospitals, nursing homes, residential areas and the like, the land is limited, and the environmental noise exceeds 5dB, a sound barrier can be adopted for prevention and treatment.
At present, the sound barrier is an important facility and is widely applied to roads, but the problem that the sound barrier is exposed in the application process is more and more concerned.
The sound barrier is generally arranged at the top of the guardrail, the sound barrier surface is close to the collision surface of the guardrail, an out-of-control vehicle (especially a large vehicle) is easy to directly collide with the sound barrier, the strength and the rigidity of an upright column are generally high for resisting wind load, the vehicle cannot guide the guardrail after colliding, so that severe tripping is easy to occur, the vehicle body is inserted into the sound barrier structure if the vehicle is heavy, and a noise reduction plate material is easy to fall under a bridge in the collision process; and the independent foundation is partially arranged at the back of the guardrail and needs a larger arrangement space, so that the width of a main structure is increased, the engineering construction cost is improved, the economy is poor, the sound barrier foundation is generally a concrete structure, the dead load of the bridge is increased, the concrete foundation needs process flows such as formwork erecting, pouring, maintenance and the like, the construction period is relatively long, the independent sound barrier is only suitable for newly-built bridges or built bridges with enough width (few), and the independent sound barrier is not suitable for most of the built bridges and has poor universality.
Through the analysis of the problems, only the single sound insulation and noise reduction function is considered in the setting process of the sound barrier in China, the comprehensive thinking and the systematic design of safety protection are lacked, and the problem is still far away from the actual engineering requirement, and needs to be solved. Therefore, the inventor provides a guidable anti-collision sound barrier structure, which not only solves the control effect on traffic noise, but also provides a solution for the problems of the normal protection function of a guardrail, the safety of the sound barrier arrangement and the like so as to meet the safety protection requirement of highway operation.
