The production of precision instruments has extremely high requirements for environmental stability, especially the control of micro-vibration.When prefabricated industrial plants are used in the production of precision instruments, micro-vibration control measures need to be taken from site selection, design to construction.At the site selection stage, it is necessary to avoid obvious vibration sources such as railways and main roads.The factory area needs to be reasonably laid out, and the precision production area should be arranged away from the main roads and power facilities of the factory area.Vibration isolation measures can be used in the foundation design, such as setting up a vibration isolation ditch, using a pile foundation or an overall raft foundation to reduce external vibration transmission.

The plant structure itself also needs to be optimized for micro-vibration control.The structural system should have sufficient stiffness and mass to avoid resonance.The arrangement of the pillars needs to be uniform, and the beam and column nodes need to be just connected to enhance the integrity.The thickness of the floor slab needs to be appropriately increased to improve the bending stiffness and quality.For particularly sensitive instruments and equipment, a separate concrete pedestal can be set up, which is connected to the main structure through a vibration isolator to further isolate vibration.Although these structural measures increase a certain cost, they are necessary to ensure the production quality of precision instruments, reflecting the adaptability of traditional industrial buildings to special needs.

Ground construction is the last threshold for micro-vibration control.The ground of the precision instrument production workshop needs to have extremely high flatness and stability.Concrete needs to use a low-shrinkage formula to control the water-to-ash ratio and reduce shrinkage and deformation.Long-term maintenance is required after pouring to ensure strength development and reduce cracks.The surface needs to be ground to achieve extremely high flatness.For ultra-precision production, epoxy self-leveling or special anti-static floors can also be used to meet the requirements of cleanliness and anti-static.After completion, vibration testing is required to verify whether the design indicators are met.This kind of excellence in construction standards ensures that prefabricated industrial plants can meet the demanding requirements of precision instrument production.
