[0027] The road and bridge construction noise insulation device of this embodiment includes a mounting base 100 and a composite sound insulation panel 200.

[0028] Mounting base 100: It has a plug groove 110 for supporting the composite sound insulation board 200. The plug groove 110 is provided with a limiting block 120. The limiting block 120 is connected to the cover 160 through a spring rod 130. The spring rod 130 is installed in the bearing grooves 140 on both sides of the mounting base 100. The cover 160 closes the opening of the bearing groove 140. The mounting base 100 has a cavity inside and a water inlet 150 on the top. Water injection can increase the stability of the base.

[0029] Composite sound insulation panel 200: includes a sound insulation panel body 210, the sound insulation panel body 210 has a filling cavity 220, which is filled with sound insulation cotton 230 to enhance the sound insulation effect. The bottom of the sound insulation panel body 210 has a limiting groove 250 for engaging with the limiting block 120 to achieve positioning. The front of the sound insulation panel body 210 has a plurality of evenly distributed slots 240. The sound absorption panel 260 is installed at the front of the sound insulation panel body 210 by inserting into the slots 240 through a plurality of evenly distributed insertion rods 270 provided on its back. The sound absorption panel 260 is preferably a polyester fiber sound absorption panel.

[0030] Working principle: During installation, the bottom of the composite sound insulation panel 200 is aligned with the insertion slot 110 of the mounting base 100 and inserted. During insertion, the bottom of the sound insulation panel body 210 presses against the limiting block 120, compressing the spring rod 130. The limiting block 120 retracts into the bearing groove 140. When the sound insulation panel body 210 is fully inserted, the limiting block 120 pops out under the elastic force of the spring rod 130 and locks into the limiting groove 250 at the bottom of the sound insulation panel body 210, thus achieving quick and stable locking and fixing. For disassembly, simply overcome the spring force to press the limiting block 120 back, and the composite sound insulation panel 200 can be pulled out of the insertion slot 110. The sound-absorbing panel 260 is quickly installed or replaced by inserting and removing the insertion rod 270 into the slot 240.

[0031] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
