1、 Grassroots treatment
Firstly, the construction ground should be treated with rough material, and any existing potholes, bumps, holes, etc. should be filled with cement to make the ground surface smooth and provide a flat foundation for subsequent construction.
2、 Laying sound insulation layer
According to the actual design requirements, laying the sound insulation material of the sound insulation layer on the ground to ensure that sound will not be transmitted underground is an important step in achieving the sound insulation function of the soundproof room on the ground.
3、 Manufacturing vibration reduction layer
1. Material preparation
-The main component of the vibration reduction layer can be plywood or wooden board, and the staff should cut it into small pieces of appropriate length in advance.
2. Processing operations
-Flip the plywood over, apply sealant, and use a press to compress and press it onto the ground to improve its adhesion.
4、 Laying seismic isolation bearings
1. Material of seismic isolation bearings
-The isolation bearing is made of polypropylene guide plate, polyurethane foam and other materials, which can reduce vibration and noise.
2. Laying operation
-The staff should first lay the seismic isolation bearings on the ground, so that they align with the foundation teeth.
5、 Laying vibration absorbing layer
1. Selection of vibration absorbing materials
-Add vibration absorbing materials such as elastic mineral wool to the vibration reduction layer.
2. Laying requirements
-Lay the vibration absorbing material on the damping plate to improve the vibration absorption effect.
6、 Ground treatment
Sprinkle high-quality glue and diamond sand, lay ceramic tiles or sound-absorbing carpets and other materials to ensure that the fire resistance of the floor meets the specified standards.
 
It should be noted that different soundproof chambers may be adjusted in the construction process according to specific needs and designs.
