Description
Technical Field
The invention belongs to the field of environmental protection, and particularly relates to a method for building a double-sided sound insulation wall.
Background
With the development of global industry, the living standard of human beings is higher and higher, but the following is a series of environmental problems such as air pollution, water pollution and noise pollution, and the like, and a plurality of problems are caused to the clothes and eating habits of people, wherein the harm of the noise pollution to the human beings is huge, but the noise pollution is also very easy to neglect. For example, in a power plant close to a residential area, a large amount of noise is generated by equipment, so that the quality of the surrounding environment is influenced deeply, the noise can cause people to feel dysphoria, tinnitus and difficulty in concentrating attention, and can cause overexcitation or heart diseases to have great influence on the physiology and psychology of people.
The control measures for the noise are generally the control of a noise source and the control of the noise in the transmission process, but the control of the noise source cannot be carried out because the cooling tower of the power plant needs good ventilation and cooling, so the control can only be carried out in the transmission process of the noise.
Therefore, it is an urgent problem to solve or reduce the harm caused by noise pollution, effectively control the noise pollution of the plant equipment, and prevent and control the noise in the noise transmission process.
Disclosure of Invention
In the process of sound transmission, different obstacles are met, and phenomena such as sound reflection and transmission occur, so that the energy of sound waves is changed. According to the sound transmission principle, the invention provides a method for building a double-sided sound insulation wall, and the wall built by the method can effectively solve or reduce the harm caused by noise pollution.
A method for building a double-sided sound insulation wall is characterized in that during construction, each layer of bricks are obliquely arranged, the inclination angle is 45 degrees, the inclination direction of the nth layer of bricks is different from that of the (n + 1) th layer of bricks and the nth layer of bricks are staggered, n is a positive integer larger than or equal to 1, and 1/2 bricks are parallel and staggered between two adjacent bricks on the same layer.
The wedge sound insulation wall comprises a row of brick width walls and two rows of brick width walls;
each layer of bricks of the single-row brick width wall is formed by arranging a row of bricks.
Two rows of bricks are arranged in each layer of width of the two rows of brick width walls, two adjacent bricks of the first row of bricks are parallel and staggered, two adjacent bricks of the second row of bricks are parallel and staggered, and the adjacent bricks of the first row of bricks and the second row of bricks are mutually perpendicular.
The width of the brick seams is 8-12 mm, and the thickness of the mortar seams is controlled to be 8-12 mm.
As shown in fig. 4, the source noise 41 from the opposite wall meets the groove between two brick corners, a large part of the reflected noise 42 is reflected back by the wall, another part of the absorbed noise 43 enters the brick body, a small part of the noise 44 with the friction viscous resistance offset is offset by the friction resistance of the brick body, and only a small part of the residual noise 45 passes through the brick body. Thereby reducing the noise and playing the role of sound insulation and noise reduction.
The wedge structure formed by arranging the bricks along the single layer and the double layer in a staggered manner not only can increase the resistance to sound waves, but also can increase the times of reciprocating reflection and the transmission path of the sound waves when the sound waves pass through, thereby consuming part of sound energy, improving the silencing effect and greatly reducing the noise outside the wall. The reflected sound waves enter the wedge structure wall, the holes in the wedge structure material and the gas are vibrated by the sound waves to generate friction, and the mutual friction between the gas and the hole wall and the viscous resistance of the air can enable the sound waves entering the wedge structure wall to be partially converted into heat energy to be consumed, so that the entering sound waves are weakened, and the noise is reduced; finally, a small part of the rest sound wave which is not reflected or absorbed is transmitted through the wedge structure material and continues to be transmitted out of the wall.
The double-sided sound insulation wall also has a weakening effect on noise outside the wall. When the noise outside the wall is transmitted to the wedge structure, the wedge structure increases the resistance of sound waves and reduces the reflected noise, so that the sound outside the wall can be reduced.
In order to ensure the silencing effect, the thickness of the mortar joint is controlled to be 8-12 mm, and the mortar joint is uniform, neat and flat; the contact part of the brick and the column cap of the foundation has a larger gap because the brick and the column cap form an included angle, and the gap is filled with cement to prevent sound leakage and avoid the phenomena of virtual filling and leakage filling.
A method for building a double-sided sound insulation wall is not limited by the type of bricks and can be selected at will, and the influence of noise on the surrounding environment can be effectively reduced only by building the bricks by rotating the angle to form a wedge effect, so that the environmental protection requirement of a noise area is met.
