Description

Anticollision wall with sound insulation function
Technical Field
The invention belongs to the technical field of collision prevention and sound insulation, and particularly relates to a collision prevention wall with a sound insulation function.
Background
With the development of economy, the construction of highway infrastructure will develop rapidly, and the influence on the environment is more obvious when the traffic develops. Therefore, the strategy of sustainable development has been paid much attention, and in recent years, with the development of highway construction industry, the application and variety of isolation facilities have been greatly developed, and the isolation facilities have increasingly shown their important roles in traffic safety and environmental protection. According to the research result of road noise, there are more than ten main factors affecting road noise, such as speed, traffic flow, etc. Wherein the noise and the speed form a linear relation, and the noise is increased by 1-1.5 decibels every time the speed is increased by 10 km/h. At present, the traveling efficiency of people is greatly improved on high-speed rails and highways, the speed of the highways is high, the flow is high, the noise on two sides along the highways can reach 70-80 decibels, the speed of the high-speed rails reaches more than 200km/h, and the generated noise is larger. Therefore, noise pollution, which is a side effect caused by high technology, is becoming more serious, and noise generated by high-speed rails, highways and inter-city express sections built in sections of residential areas has already seriously influenced the lives of surrounding residents. Therefore, there has been a high social interest in how to reduce the influence of these noises on the lives of residents. A sound-proof wall is an obstacle, also called a sound barrier, which is disposed between a sound source and a sound receiving point to block sound. The arrangement of sound-insulating walls on roads is an effective way to control noise from the transmission path. When the sound pressure level of noise at 1m outside the window of the street-approaching building in the daytime exceeds 70dB and at night exceeds 55dB, noise reduction measures are taken. At present, with the rapid development of high-speed rails, urban railways, high-grade highways and urban expressway construction, urban traffic noise pollution is getting worse and worse, sound insulation walls are becoming hot points for road engineering research and development, the sound insulation effects of the existing sound insulation equipment are uneven, the rationality of the structure is not considered, the shape is rigid and single, the sound insulation effect with higher cost is not obvious, the sound insulation wall is easy to damage when collision occurs, meanwhile, most of the expressway and highway anti-collision walls have poor buffering energy consumption, when an automobile is out of control and collides, the automobile is destroyed and the people are killed, especially broken fragments of the anti-collision walls are more serious, the danger cannot be effectively prevented, and the occurrence rate of traffic accidents also shows a rising trend along with the large development of highways, urban overpasses and the like and the great increase of the quantity of automobile protection in the world. The existing anti-collision wall in the current market does not have the sufficient buffering and damping effects when in use, after an automobile is collided, the automobile can only be damaged by self deformation to absorb energy, the deformation capacity and the energy absorption capacity are limited, the anti-collision wall is easy to break under the collision effect of the automobile, the anti-collision wall cannot be normally used, and secondary damage is easily caused to the safety of the automobile and crewmembers.
