Embodiment Construction

[0020] The present invention will be further described below with reference to the accompanying drawings and examples, and the embodiments of the present invention include but not limited to the following examples.

[0021] Such as Figure 1 to Figure 3 As shown, a sound barrier for rail traffic roads includes a plurality of sound barrier units connected in sequence; the sound barrier unit includes a shell 1 with a front panel 2 and a rear panel 3; a honeycomb core is arranged between the front panel 2 and the rear panel 3 4. The inner top and inner bottom of the shell 1 between the honeycomb core 4 and the rear panel 3 are respectively provided with a sound insulation board 6 and a sound absorption board 7 to form a continuous M or W-shaped channel 5; the channel is filled with sound-absorbing material 8; this The noise generated during the operation of the train in the invention passes through the front panel 2, the honeycomb core 4, the M or W-shaped channel 5, and the rear...

Abstract

The invention discloses a sound barrier for a rail traffic road. The problems that in the prior art, an existing sound barrier cannot dislodge the train starting load acting on the surface of the existing sound barrier, thus the service life of the sound barrier is shortened, and the energy-saving lighting demand of a train at night cannot be met are mainly solved. The sound barrier for the rail traffic road comprises a plurality of sequentially-connected sound barrier units, and the sound barrier units comprise outer shells with front face plates and rear face plates. Honeycomb cores are arranged between the front face plates and the rear face plates, and sound insulation plates and sound absorption plates are arranged on the positions, between the honeycomb cores and the rear face plates, of the inner tops and the inner bottoms of the outer shells correspondingly and form continuous M-shaped or W-shaped channels. The channels are filled with sound absorption materials. Through the scheme, the purposes of prolonging of the sound barrier service life and energy conservation are achieved, and the very high practical value and promotional value are achieved.

Description

technical field [0001] The invention relates to the field of sound barriers, in particular to a sound barrier for rail transit roads. Background technique [0002] Sound barriers are mainly used for sound insulation and noise reduction of roads, expressways, elevated composite roads and other noise sources. It is divided into reflective sound barriers for pure sound insulation, and composite sound barriers that combine sound absorption and sound insulation. The latter is a more effective sound insulation method. With the progress of society and the development of cities, people's living standards continue to improve, urban traffic and intercity traffic has become the most closely related issues to us. Therefore, reducing the disturbance of noise to residents on both sides of the road has become an important task in the current urban construction of our country. Great convenience, but residents who live near these highways, light rails and high-speed rails suffer from traff...
