Noise prevention and control device used for expressway

Abstract

The invention relates to the technical field of noise prevention and control devices, in particular to a noise prevention and control device used for the expressway. The noise prevention and control device used for the expressway comprises supporting mechanisms and a noise reduction mechanism, the noise reduction mechanism is arranged between the two supporting mechanisms, first installing holes are formed in a left installing rack and a right installing rack respectively, bases are horizontally welded to the lower surfaces of stand columns, foot screw holes are formed in the four corners of each base, second installing holes are formed in the centers of fixing plates, connecting plates are perpendicularly welded to the edges of the two short sides and the long side of each fixing plate, and first connecting holes are formed in the centers of the connecting plates. The design of a combination with an expressway safe fence is adopted, the device and the expressway safe fence are fused,the multiple sets of fixing plates and connecting plates and noise reduction tubes are arranged, the number of the noise reduction tubes can be selected for installation according to the traffic flowof the expressway, the surfaces of the noise reduction tubes are rough, and noise can be effectively absorbed.

Description

technical field [0001] The present invention relates to a noise prevention device. Technical field, especially a noise prevention and control device for highways. Background technique [0002] Traffic noise is mainly generated in the process of vehicle operation, and its influence ranges widely and lasts for a long time. Long-term exposure to noise can cause symptoms such as hearing loss, decreased sleep quality, abnormal physiological systems, and poor mental state. [0003] Many existing municipal green belt noise placement devices are simple in structure and light in weight, and are not suitable for highways where the road requirements are higher than urban roads; currently, there are many ways to reduce noise with green belts. Most of them are planted in the central division of the left and right traffic lanes, and the green belt noise reduction method is rarely used on both sides of the road. A single steel frame structure with a simple structure cannot minimize acci...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the problem that many municipal green belt noise placement devices are simple in structure and light in weight, and are not suitable for highways where the road requirements are higher than urban roads, the present invention provides a Noise prevention and control device for expressway. This device is composed of two parts: support mechanism and noise reduction mechanism. The structure is diverse. Disassembly and installation save time and effort.

[0006] In order to solve the problem that guardrails are installed on both sides of the highway on both sides of the highway, a single steel frame structure is adopted, the structure is simple, and the accident damage cannot be minimized when a safety accident occurs, the invention provides a noise barrier for highways. The prevention and control device, through the organic combination with the safety guardrail of the expressway, has changed the shortcoming of the single structure of the traditional guardrail. The staggered gaps can absorb the impact of many collisions, reducing safety losses
