Noise barrier structure for road construction

Abstract

The invention discloses a noise barrier structure for road construction, and relates to the technical field of road construction. The noise barrier structure comprises a frame body, frame body connecting plates, a mounting assembly and an inner core body, the frame body connecting plates are arranged on the left side and the right side of the frame body, the side walls of the bottoms of the frame body connecting plates are connected with the mounting assembly through connecting columns, a front cover plate and a rear cover plate are embedded in the front side and the rear side of the frame body, a sealing plug plate is embedded in the side wall of the top end of the frame body, and the inner core body is embedded in the frame body. Inner core grooves are formed in the upper end and the interior of the frame body, sealing gaskets are bonded to the inner walls of the inner core grooves, the frame body and the inner core body can be assembled through the sealing gaskets, meanwhile, an integrated wrapping structure is formed between sound insulation glass and inner plates of the inner core body, and the mutual sealing performance is extremely high; and meanwhile, the mounting assembly abuts against the side wall of the road pile or the bridge body through an abutting plate, the connection compactness between the frame body connection plates and the mounted part can be improved, and meanwhile the purpose of being suitable for the mounted parts with different thicknesses can be achieved.

Description

technical field [0001] The invention belongs to the technical field of road construction, in particular to a road construction noise barrier structure. Background technique [0002] When the existing frog wear inspection ruler is in use, due to the different specifications of the rails, the measuring ruler on the third of the rail surface on the inspection ruler needs to be manually adjusted in advance according to the rail specification. Large errors will affect the overall measurement effect. [0003] Existing public document, CN112900297A-a kind of sound insulation screen that is used for high-speed railway interspersed in downtown area, discloses a kind of noise barrier that is used for high-speed railway interspersed in downtown area, comprises base, supporting steel column, sound insulation screen, soundproof window, Fixing cap, metal rod and rubber plate; the section of the supporting steel column is I-shaped, the bottom end of the supporting steel column is installe...

AI Technical Summary

Problems solved by technology

[0005] 1. One of the above-mentioned sound-proof screens used for high-speed railways interspersed in downtown areas. The sound-proof screen 3 consists of a metal plate 31, a sound-absorbing board 32, a fire-proof and moisture-proof fiberboard 33 and a sealing board 34. Two fire-proof and moisture-proof fiberboards 33 are installed on At both ends of the sound-absorbing board 32, two metal plates 31 are provided and installed on the outer sides of the two fire-proof and moisture-proof fiber boards 33 respectively. Most of it is absorbed by the sound-absorbing board 32, and some of it bounces back. Among them, the metal plate and the moisture-proof limiting board cannot absorb noise, but only have the effect of transmitting and reducing noise energy. The structure of the sound-absorbing panel and the sound-absorbing principle of the sound-absorbing panel are announced, so the actual purpose of achieving sound insulation through sound-absorbing effect is not valid

[0006] 2. One of the above-mentioned noise barriers used for high-speed railways interspersed in downtown areas, which uses fixed caps to be inserted on the top of the supporting steel columns, and the fixed caps are interspersed and connected by metal rods, so as to achieve the purpose of connecting the entire noise barrier , this method can only be used with the sound insulation barrier located on the same straight line, but it is not applicable to the sound insulation barrier of the curved installation method, and then forms a partial series structure fault, that is, the problem of losing the original series function

[0007] 3. One of the above-mentioned sound insulation screens used for high-speed railway interspersed in the downtown area, the rubber plate on it is located between the two bases, two sound insulation screens are installed between the two supporting steel columns, and the sound insulation windows are installed On the two supporting steel columns between the two soundproof screens; it can be seen from the above that the soundproof screen and the soundproof window do not belong to an integrated structure, but are carried out in the form of inlaid sets, and then the soundproof window and the soundproof screen. The connection is not stable, and there are also huge gaps, and the sound insulation effect of the overall structure after its composition will be greatly weakened
