2nd, sound-absorbing effect is more preferable:The abatvoix of the system uses composite, i.e., above and below combine for two layers, surface layer is
With the concave sound-absorbing surface layer of streamlined(Surface layer uses the porous foamed aluminum sheet of synthetic resin sheet material or porous cloth
It is made), basic unit be cellular cavity inorganic mineral material plate;The composite wood combined by sound-absorbing surface layer and base material
Material enhances sound-absorbing effect, and with double-deck sound absorption function, the composite is also more environmentally-friendly;It is recessed that surface layer 11 is provided with streamlined
The more favourable air-flow of the prefabricated air flow guiding groove 13 reduction air pressure of shape.
3rd, adaptability is stronger:The keel of the system are using otic placode as stationary nodes, and more piece keel are cut with scissors by otic placode
Connect and bend and be fixed on tunnel inner wall, it is curved that the upper sideline of the side board 22 of keel is designed to that wave-like is more beneficial for keel
Song, therefore the keel of the system are mountable to the tunnel inner walls of various curvature, particularly some corners, irregular inwall have
Stronger adaptability.
4th, convenient later maintenance economy:As long as changing standard-sized abatvoix during maintenance, convenient disassembly is cost-effective.
5th, with application and popularization value:With continuing to develop for high-speed railway and highway, the requirement to engineering construction
More and more higher, by the technology of the present invention, can further solve the pollution of tunnel internal noise, engineering actual demand amount is also more next
Bigger, market prospects widely, add the system, possess advantage with low cost, easy for installation, easy to maintenance, possess one
Fixed promotional value.
Below, technical characteristic in conjunction with the accompanying drawings and embodiments to a kind of modular tunnel inner wall sound-absorbing system of the present invention
It is further described.
