Description

Technical Field

[0001] The invention belongs to the technical field of anti-collision and sound insulation, and in particular relates to an anti-collision wall with sound insulation function. Background Art

[0002] With the development of economy, the construction of highway infrastructure will develop rapidly. As the traffic develops, the impact on the environment will become more obvious. Noise pollution is becoming more and more serious. The noise generated by high-speed railways, highways and intercity express sections built in residential areas has seriously affected the lives of surrounding residents. Therefore, how to reduce the impact of these noises on residents' lives has received great attention from the whole society. Soundproof walls are obstacles set between the sound source and the sound receiving point to block the sound, also known as sound barriers. Setting up soundproof walls on highways is an effective way to control noise from the propagation path. When the noise sound pressure level at 1m outside the window of a building facing the street exceeds 70dB during the day and exceeds 55dB at night, noise reduction measures should be taken. Nowadays, with the rapid development of high-speed rail, urban rail, high-grade highway and urban expressway construction, urban traffic noise pollution is becoming more and more serious. Soundproof walls are becoming a hot spot for road engineering research and development. The sound insulation effect of current sound insulation equipment is uneven, and the rationality of the structure is not considered. The shape is rigid and single, and some of them are costly but the sound insulation effect is not obvious. They are easily damaged in the event of a collision. At the same time, most of the crash barriers on highways and roads have poor buffering and energy consumption. When a car loses control and hits, it often causes car damage and death, especially the broken crash wall fragments that injure people more seriously, and cannot effectively prevent the danger from happening. With the large-scale construction of highways, urban interchanges, etc. and the substantial increase in the number of cars in the world, the incidence of traffic accidents is also showing an upward trend. At present, the existing crash barriers on the market do not have sufficient buffering and shock absorption when in use. After a car hits, it can only rely on its own deformation damage to absorb energy. The deformation capacity and energy absorption capacity are limited, and the crash barrier is easy to break under the impact of the car, resulting in inability to use normally, and it is also easy to cause secondary damage to the safety of vehicles and crew members. Summary of the invention

[0003] In order to solve the above-mentioned technical problems, the present invention provides a crash barrier with sound insulation function, which effectively combines sound insulation and crash protection, can provide stable damping force and shock absorption and energy dissipation capacity, not only can the service life of the crash barrier be greatly increased, but also has the ability to protect vehicles from collision damage.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A crash barrier with sound insulation function, comprising a sound insulation wall panel and a crash barrier unit. A plurality of crash barrier units are arranged horizontally above the ground. The main part of the crash barrier unit is the crash barrier unit. Crash cushions are arranged on both sides of the crash barrier unit, and an energy-absorbing assembly is arranged in the middle. The energy-absorbing assembly consists of an upper sealing plate, a lower sealing plate, and drum-shaped energy-absorbing steel plates on both sides.

The sound-absorbing panel outside the sound insulation material is provided with an absorption Sound hole, pass the cable through the drum-shaped energy-absorbing steel plate and the sound insulation wall panel, and fix them with fixing bolts. An energy-absorbing composite plate is arranged on the outside of the energy-absorbing assembly. The energy-absorbing composite plate is composed of an outer frame plate, an extruded energy-absorbing spring in the outer frame plate, and energy-absorbing materials between the extruded energy-absorbing springs. The area between the energy-absorbing composite plate and the anti-collision pad is a sparsely reinforced steel bar area, and the area between the energy-absorbing composite plate and the energy-absorbing assembly is a densely reinforced steel bar area. A steel bar hole is arranged on one end face of the anti-collision wall body, and embedded steel bars are arranged on the other end face. Two adjacent anti-collision wall monomers are connected by inserting the embedded steel bars into the corresponding steel bar holes.

[0006] Furthermore, the energy dissipation material adopts high damping rubber.

[0007] Furthermore, the main body of the anti-collision wall is made of lightweight concrete with added damping material, and the damping material is made of a mixture of polyvinyl alcohol, polypropylene emulsion and styrene-butadiene latex.

[0008] Furthermore, the main body height of the anti-collision wall is not less than 1.8m.

[0009] Furthermore, the height of the sound insulation wall panel is not less than 3m.

[0010] Furthermore, the drum-shaped energy-absorbing steel plate, the upper sealing plate and the lower sealing plate are made of low-yield-point energy-absorbing steel plates.

[0011] Furthermore, the sound insulation material is selected from one of glass fiber, mineral fiber and plant fiber, and the thickness is set at 100 to 160 mm.

[0012] The advantages and effects of the present invention are:

[0013] The beneficial effect of the present invention is that it effectively combines sound insulation and anti-collision to prevent the sound insulation wall panels from being damaged by external collisions. It has a reasonable structure, is convenient to construct, has a fast construction speed, and has good economic effects. It can achieve good sound insulation and noise reduction effects and has good integrity. The energy-consuming composite panels and energy-consuming composite bodies that are set can absorb impact energy and can greatly buffer the impact force of the car. In addition, the shock-absorbing protection of the anti-collision pad can achieve a double protection effect. The energy-absorbing cavity that is set can greatly increase the anti-collision buffering effect of the anti-collision wall and provide stable damping force and shock-absorbing energy-absorbing capacity.
