A substation anti-noise wall and construction method

Abstract

The present invention involves a substation anti -noise wall and construction method. It includes the foundation and wall. The internal setting of the wall is equipped with an empty cavity A, the internal cavity A of the wall is set with noise plates, the noise plate passes throughRiveting and wall riveting, the surface of the noise plate is set up with noise reduction, the surface of the inner wall of the wall is equipped with radiation -proof net, the surface of the radiation -proof network is set with noise reduction plate, the upper surface of the noise reduction plate is evenly vertical.Set up noise reduction bars. There is an empty cavity B inside the noise reduction bar. The noise reduction plate between the two noise reduction bars is evenly set with sound absorption holes.By fixed connection with the wall with the expansion bolt, the upper part of the pitch board is set to the tilt structure. The horizontal surface of the upper surface of the pitch board is set with anti -sound plates. The invention structure is simple, convenient for construction, good noise reduction effect, can be effectively adsorbed effectivelyThe advantages of noise, isolation noise, and can shield radiation at the same time.

Description

technical field [0001] The invention belongs to the field of anti-noise and anti-radiation walls, in particular to a substation anti-noise wall and a construction method. Background technique [0002] The noise generated during the operation of the substation mainly comes from the electromagnetic noise of electrical equipment such as main transformers, high-voltage reactors, circuit breakers, and outdoor power distribution devices, and the aerodynamic noise generated by cooling fans. (GB12348-2008) Class 2 standard requirements: control within 60dB(A) during the day and within 50dB(A) at night, in order to effectively control the environmental noise, so that the noise interference generated by the 1000 kV substation project does not disturb the residents, the traditional substation The sound insulation wall of the company adopts ordinary brick wall, which has poor sound insulation effect and no sound absorption function, which makes the noise control range outside the substa...

[0002] The noise generated during the operation of the substation mainly comes from the electromagnetic noise of electrical equipment such as main transformers, high-voltage reactors, circuit breakers, and outdoor power distribution devices, and the aerodynamic noise generated by cooling fans. (GB12348-2008) Class 2 standard requirements: control within 60dB(A) during the day and within 50dB(A) at night, in order to effectively control the environmental noise, so that the noise interference generated by the 1000 kV substation project does not disturb the residents, the traditional substation The sound insulation wall of the company adopts ordinary brick wall, which has poor sound insulation effect and no sound absorption function, which makes the noise control range outside the substation large, and the radiation of the substation is relatively serious, which is not conducive to the health of the people living around.
