Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-5, a rail transit sound barrier with a guiding function comprises a sound barrier plate 1, a sign 2 is bolted on the right side of the sound barrier plate 1, the sound barrier plate 1 comprises a sound absorbing layer 11, steel sound insulating layers 12 are adhered on both sides of the sound absorbing layer 11, an anti-corrosion layer 13 is coated on one side of the steel sound insulating layer 12 away from the sound absorbing layer 11, the sound absorbing layer 11 comprises sound absorbing cotton 111 and a high-density rock wool board 112, the anti-corrosion layer 13 comprises epoxy powder coating 131, an adhesive 132 and a polyethylene layer 133, by arranging the sound barrier plate 1, the sign 2 and a support frame 3, the problems of low utilization rate of one side of the sound barrier close to a rail and high difficulty in maintenance and replacement of the rail transit sound barrier are solved, the rail transit guiding function is provided, the service life of the sound barrier is prolonged, the guiding function of a driver is realized by using the surface of the rail transit sound barrier, and the maintenance and replacement frequency is reduced by reinforcing the rail transit sound barrier, the practicability and the durability of the rail transit sound barrier are improved.
In this embodiment, the right side of the sound barrier panel 1 is a sound source side, the top of the sound barrier panel 1 is set to be a structure inclined to the right, and an inclined included angle on the right side of the sound barrier panel 1 is 135 degrees to 150 degrees, so that the bending structure of the sound barrier panel 1 can effectively reflect noise and weaken the propagation of the noise.
In this embodiment, inhale cotton 111 and be located high density rock wool board 112 left side, inhale cotton 111 and be located left steel puigging 12 bonding of sound, high density rock wool board 112 and the steel puigging 12 that is located the right side bond, through inhaling the dual setting of cotton 111 of sound and high density rock wool board 112, sound that can the effective absorption steel puigging 12 pierce through and come increases the sound barrier effect of sound barrier board 1.
In this embodiment, epoxy powder coating 131, adhesive 132 and polyethylene layer 133 set gradually from inside to outside, and epoxy powder coating 131 is scribbled in one side that steel puigging 12 kept away from sound absorbing layer 11 in one side that adhesive 132 was kept away from to epoxy powder coating 131, and setting through anticorrosive coating 13 can effectually protect sound barrier board 1, increases sound barrier board 1's life.
In this embodiment, sign 2's the equal bolt in front and the back has support frame 3, and support frame 3's the other end and the bolt of sound barrier board 1 play the effect of consolidating sign 2 through setting up support frame 3, prevent that the air current that train or subway drove from blowing sign 2 off.
