Detailed Description
Fig. 1 and 2 show a near-rail sound absorption and insulation device, which is composed of a connecting piece 2, a mounting bolt 3 and a noise reduction body 4.
Firstly, flattening the field on two sides of the railway sleeper to ensure that the field is uniform without bulge and depression; then the connecting piece 2 is fixed on the sleeper 1 by the mounting bolt 3, and finally the noise reduction body 4 is connected and fixed with the connecting piece 2.
The connecting piece 2 is made by bending a 10mm thick steel plate, one end of the connecting piece is a U-shaped groove connecting end, the other end of the connecting piece is a flat plate, and the U-shaped groove connecting end and the flat plate are both provided with connecting holes with the diameter of 18 mm. The U-shaped channel connection end is snapped onto the sleeper face and secured using expansion bolts M16 x 100. The flat plate of the connector and the noise reducing body are fixed by using bolts M16 x 50. The function of connection and fixation is achieved.
The mounting bolts are connected with the sleeper through expansion bolts M16 and 100, and are connected with the noise reduction body through common bolts M16 and 50.
