Sound Barrier Foundation Attachment Bolt Accessible Box Base

Abstract

The invention discloses a sound barrier base with foundation connecting bolts capable of being overhauled and a sound barrier with the base, and belongs to the field of sound barriers. The sound barrier base is a box body with at least one opening. The box body comprises a top plate, a bottom plate and stand plates connected between the top plate and the bottom plate. The bottom plate of the box body is provided with through holes corresponding to the foundation connecting bolts of the sound barrier. The sound barrier foundation connecting bolts are located in the base, the base is not closed and is provided with the opening, the base is located on the inner side of the sound barrier, in other words, the base faces the railway side, and therefore maintenance workers can maintain and overhaul the foundation connecting bolts on the railway side through tools, and the sound barrier base is simple in structure and convenient to install.

Description

technical field [0001] The invention relates to the field of sound barriers, in particular to a sound barrier foundation connecting bolt repairable box base used for road, railway and urban rail transit bridge sound barriers. Background technique [0002] At present, the connecting bolts 3 of the sound barrier foundations of highways, railways, and urban rail transit bridges that have been built or are being built in China are basically arranged on both sides of the H-shaped steel column 1, that is, the inner and outer sides of the sound barrier, and are symmetrically distributed. See the schematic diagram figure 1 As shown, after the sound barrier sound-absorbing panel 2 is inserted, the bolts on the outside of the sound barrier are difficult to carry out inspection and maintenance operations. [0003] In the later stage of operation and maintenance, due to the barrier of the sound barrier, it is necessary to walk a long distance to the outside of the sound barrier to repai...

Problems solved by technology

[0002] At present, the connecting bolts 3 of the sound barrier foundations of highways, railways, and urban rail transit bridges that have been built or are being built in China are basically arranged on both sides of the H-shaped steel column 1, that is, the inner and outer sides of the sound barrier, and are symmetrically distributed. See the schematic diagram figure 1 As shown in the figure, after inserting the sound-absorbing panel 2 of the sound barrier, the bolts on the outside of the sound barrier are difficult to carry out inspection and maintenance operations

[0003] In the later stage of operation and maintenance, due to the barrier of the sound barrier, it is necessary to walk a long distance to the outside of the sound barrier to repair the foundation bolts located on the outside; or artificially erect facilities to climb to the outside of the sound barrier, which is very dangerous and involves viaducts When the outer side of the sound barrier cannot be climbed by manpower, it is difficult to carry out normal maintenance and repair of the bolts on the outer side of the sound barrier

After a long period of time, the foundation bolts of the vehicle may become loose, resulting in the instability of the sound barrier and the falling of the plate, causing casualties, property losses, and affecting railway traffic. The consequences are very serious.
