Problems solved by technology

Direct placement and positioning is to install the sound-absorbing panels sequentially along the direction of the track and at intervals according to the positioning requirements. The installation is simple, the efficiency is high, and the maintenance is convenient. The sound-absorbing panel and the track cap are connected by adhesive mortar for permanent rigid fixation, the installation can be adjusted greatly, the overall surface is smooth and beautiful, and the installation is firm, but the construction operation is complicated , which is not conducive to the replacement and maintenance of track sound-absorbing panels, and also affects the safe operation of trains; the overall connection is fixed by using connecting steel plates and connecting bolts to connect the sound-absorbing panels on both sides and the middle of the rail into a whole. It will cause the rail foundation and even the entire track to be connected to conduct electricity, resulting in unpredictable and serious consequences

Embodiment 1

[0031] A track sound-absorbing panel such as Figure 1 to Figure 4 As shown, the track sound-absorbing panel 1 is a cuboid, the upper surface of the track sound-absorbing panel 1 is provided with a sound-absorbing groove 12, and the lower surface of the track sound-absorbing panel 1 is provided with an arc-shaped groove 13, and the sound-absorbing groove 12 and the arc-shaped groove 13 are mutually The purpose of the parallel and arc-shaped grooves is to facilitate the fixing of the sound-absorbing panels of the track, to prevent the unfixed sound-absorbing panels of the tracks from being repeatedly damaged by the vibration and wind rheology generated during the operation of the subway locomotive, and to ensure and improve safety; the sound-absorbing panels of the tracks are equipped with The elliptical track holes 11, the elliptical track holes 11 include elliptical track holes I 111, 112 and elliptical track holes II 113 in a triangular distribution; The middle of the adjace...

Embodiment 2

[0036] A method for installing and constructing a track sound-absorbing panel, the method for installing and constructing comprises the following steps:

[0037] A. Prefabricated track sound-absorbing panel 1:

[0038] The track sound-absorbing panel 1 with elliptical runway holes is prefabricated in the factory. The long axis of the elliptical runway through-hole forms an angle of 45° or 135° with any side line of the track sound-absorbing panel 1. The positions of the elliptical runway through holes I 111 and 112 are selected on the track. In the middle of the two adjacent sides of the sound-absorbing panel, the position of the elliptical runway through hole II 113 is selected on the diagonal line of the other two adjacent sides of the track sound-absorbing panel; after the maintenance of the track sound-absorbing panel 1 with the elliptical runway through hole reaches the design strength , after passing the quality inspection, it will be transported to the laying site;

Abstract

Disclosed is a track sound-absorbing board. The track sound-absorbing board is a cuboid, sound-absorbing grooves are formed in the upper surface of the track sound-absorbing board, arc-shaped grooves are formed in the lower surface of the track sound-absorbing board, and the sound-absorbing grooves and the arc-shaped grooves are parallel; elliptical runway through holes are formed in the track sound-absorbing board and comprise elliptical runway through holes I and an elliptical runway through hole II, the elliptical runway through holes I are arranged in the middles of the two adjacent edges of the track sound-absorbing board, the elliptical runway through hole II is arranged at the diagonal position of the rest two adjacent edges of the track sound-absorbing board, and the long-axis line of the elliptical runway through holes and the side line of the track sound-absorbing board has the angle being 45 or 135 degrees. According to the invention, the track sound-absorbing board can be connected firmly with a bearing platform foundation or the track sound-absorbing boards can be connected firmly, the connection position can be chosen flexibly, and rebars of the bearing platform foundation and a track circuit are effectively avoided; and construction is simple, once-step installation is in place, maintenance and replacement are safe and convenient, and the safe operation of trains is guaranteed.

Description

technical field [0001] The invention relates to the field of rail traffic noise control, in particular to a rail sound-absorbing panel and its installation and construction method. Background technique [0002] Cement-based ceramsite track sound-absorbing panel is a new type of track noise reduction product, which can effectively absorb wheel-rail noise, has a good effect on improving the urban rail transit environment, and has broad application prospects. [0003] The main installation methods of track sound-absorbing panels currently applied to engineering are direct placement and positioning, permanent rigid fixation, and integral connection and fixation. Direct placement and positioning is to install the sound-absorbing panels sequentially along the direction of the track and at intervals according to the positioning requirements. The installation is simple, the efficiency is high, and the maintenance is convenient. The sound-absorbing panel and the track cap are connec...
