SUMMERY OF THE UTILITY MODEL
The utility model mainly aims to provide a sound insulation barrier for road construction, which overcomes the defects in the prior art;
in order to solve the technical problem, the utility model provides a following technical scheme:
the utility model provides a sound insulation barrier that road construction used which characterized in that: the shielding structure comprises a shielding body and a stabilizing base, wherein the bottom of the shielding body is fixedly connected to the stabilizing base, reinforcing plates are connected to two ends of the shielding body, warning lamps are connected to two ends of the top of the shielding body, the shielding body is a whole body with radian, a sound-absorbing material plate is connected to the surface of the inner wall of the shielding body, a through hole is formed in the center of the sound-absorbing material plate, a sound-absorbing cavity is formed in the sound-absorbing material plate, a sound-absorbing block is arranged in the sound-absorbing cavity, the sound-absorbing block is a pyramid, and;
optionally, the sound-absorbing material plates are spliced on the surface of the inner wall of the barrier body, so that generated noise can be primarily absorbed;
optionally, the surface of the sound-absorbing material plate is concave and takes the through hole as a center, so that noise which cannot be eliminated can enter the sound-absorbing cavity through the through hole for retreatment;
optionally, the sound absorption blocks are arranged in number, the sound absorption blocks are in the same size and are tightly connected, and the sound absorption blocks of the pyramids are tightly connected, so that multiple reflection absorption can be performed on sound waves, and the sound waves are gradually eliminated;
optionally, the reinforcing plate is integrally arc-shaped, the reflection area of sound waves is increased by the arc-shaped sound-proof screen, the diffraction way of the sound waves at the top of the sound-proof screen is reduced, and the noise reduction effect is obviously increased.
Optionally, the reinforcing plate is laid on a layer of frame of the barrier body, and the arc-shaped structure is more convenient for absorbing and reflecting sound waves;
has the advantages that: the utility model discloses it is whole that the adoption arc structure is optional, and the arc sound-proof screen has increased the reflection area of sound wave, reduces the sound wave in the diffraction way at the sound-proof screen top, and noise reduction effect obviously increases, and the sound wave is through the pyramid that has the through-hole inhale sound material board and inhale the sound intracavity and inhale the sound piece and carry out a lot of to the sound wave that produces simultaneously, can the biggest effect handle the noise, and the effect that gives sound insulation is obvious, and simple structure is reasonable, is worth promoting.
