Embodiment 1

[0044] This example provides an integral groove base direct-buried self-supporting non-metallic sound barrier, including the main body of the sound barrier. The main body of the sound barrier is a direct-buried self-supporting structure. Four ribs, the panel, the back plate and the four ribs form a middle cavity, and the middle cavity is not filled with sound-absorbing materials. like Image 6 As shown, the large-cavity sound barrier is not filled with sound-absorbing boards, the height is 3m, the backboard and front panel reinforcement is 200mm×200mm medium-strength prestressed steel wire mesh with a nominal diameter of 5mm, and the backplane and panel thickness is 30mm; the lower end is made of The pre-buried type is fixed by grouting, and the vertical joints of the sound barrier are sealed with water-stop strips. The surface opening rate is 20%, and it is installed on both sides of the road to absorb noise;

Embodiment 2

[0050] This example provides a self-supporting non-metallic sound barrier directly buried with an integral groove base, such as Figure 1-5 As shown, in this example, in addition to filling the sand-based particle sound-absorbing panel (wherein, the sand is quartz sand, and the particle size of the sand is 0.5-1.0mm; the bending bearing capacity of the sand-based sound-absorbing panel is ≥7kPa, the impact resistance is ≥35J, Connecting material is 72.5R grade Portland cement), other conditions are all identical with embodiment 1.

Embodiment 3

[0052] In this example, except that the foamed metal sound-absorbing board is filled (wherein, the material of the foamed metal sound-absorbing board is a foamed aluminum material), other conditions are the same as in the first embodiment.

Abstract

The invention discloses an integral groove-based directly-buried self-standing non-metal sound barrier and a mounting method thereof, and belongs to the technical field of sound barriers, the sound barrier comprises a sound barrier main body, the sound barrier main body is of a directly-buried self-standing structure, and the sound barrier main body comprises a panel with holes in the surface, a back plate with no holes in the surface and four partition rib plates; and the panel, the back plate and the four-partition rib plate form a middle cavity, and the middle cavity is filled with sound absorbing materials. The sound barrier can be fixedly connected in the vertical direction and the transverse direction through detachable connecting pieces, and disassembly and cyclic utilization are easy; and meanwhile, when the sound barrier is under the wind pressure of + / -4 kpa, the maximum elastic deflection is smaller than or equal to L / 350, the impact resistance is larger than or equal to 35 J, the mechanical requirement of the high-speed rail sound barrier is met, the acoustic performance sound insulation is larger than or equal to 50 dB, and the sound absorption coefficient NRC is larger than or equal to 0.7.

Description

technical field [0001] The invention relates to the technical field of sound barriers, in particular to a direct-buried self-supporting non-metallic sound barrier with an integral groove base and an installation method thereof. Background technique [0002] With the development of urban construction, the problem of traffic noise has attracted more and more attention. The sound source of traffic noise is flowing, the sound is extremely high, and the interference time is long. It has a wide range of influence and has seriously disrupted the normal life and rest of urban and rural residents. In order to solve this noise problem, there are currently three ways of road noise reduction, noise barrier noise reduction and sound insulation window noise reduction. [0003] At present, non-metallic sound-absorbing and sound-insulating panels have been widely used on both sides of railways and roads, and the demand is increasing. The conventional method is to set steel columns on both ...
