Background
In recent years, China builds a large amount of high-speed rails and puts the high-speed rails into operation, and a sound barrier system is applied in a large amount for solving the noise pollution generated by the operation of the high-speed rails. Sound barriers are formed by placing sound insulation between the sides of the source to provide significant additional attenuation of sound waves propagating therethrough, thereby reducing the noise impact in certain areas. The sound barrier widely used at present mainly comprises two parts, namely a steel structure upright post and a sound absorption and insulation plate (namely a screen body), wherein the upright post is a main stressed component of the sound barrier and is fixed on a road anti-collision wall or an embedded steel plate at the edge of a track through rivets or bolts or welding.
Because the operating environment of the sound barrier is quite severe, the sound barrier is exposed in the air and exposed to the sun and rain, and the steel sound barrier has the corrosion problem, the service life of the sound barrier is greatly reduced. The present inventors have designed a non-metallic sound barrier, but there is no mold for making the sound barrier.

The utility model aims to provide a road sound barrier die which can be used for quickly manufacturing a sound barrier made of a non-metal material and improving the production efficiency.
In order to solve the technical problem, the road sound barrier provided by the utility model comprises a mould frame body with an open top, and is structurally characterized in that: the upper surface of the lower bottom wall of the die frame body is connected with a lower template, a plurality of protruding columns are densely distributed on the upper surface of the lower template, and two opposite side walls of the die frame body are correspondingly provided with long grooves and protruding strips.
The lower parts of at least two opposite side walls of the four side walls of the die frame body are provided with concave grooves which are concave inwards, and the opposite sides of the lower template are inserted into the concave grooves.
The lower ends of four side walls of the die frame body are hinged to four edges of the lower bottom wall, and locking devices capable of locking the side walls in a vertical state are arranged on two adjacent side walls.
The locking device comprises a swing arm hinged to one of the two adjacent side walls, a locking plate is arranged on the other side wall, a locking groove for inserting the swing arm is formed in the locking plate, and the swing arm is inserted into the locking groove and then fixed to the two adjacent side walls.
The two opposite side walls are provided with insertion holes for inserting steel wires.
After the structure is adopted, the sound absorption block and the box body are placed in the die frame body, the bottom of the sound absorption block is placed on the protruding column, concrete material is put into the die frame body, and the nonmetal sound barrier with the novel structure is formed after the concrete is solidified; the lower template and the protruding columns can not only support structures such as the sound absorption block, but also automatically form sound absorption holes of the sound barrier.
In conclusion, the utility model has the advantages of simple structure, capability of quickly manufacturing the non-metallic sound barrier and improvement of production efficiency.
