Underground precise laboratory efficient vibration isolation method

Abstract

The invention discloses an underground precise laboratory efficient vibration isolation method. A retaining wall is constructed on the outer side of an outer wall of an underground precise laboratory. The space between the outer wall of the laboratory and the retaining wall is filled with a barrier material. According to the method, the retaining wall technology is creatively introduced into the underground laboratory structure, so that influences of outside environment vibration are greatly weakened on the aspect of transfer paths; and meanwhile, based on the theory of vibration isolation by barriers, the space between the retaining wall and the outer wall of the laboratory is filled with the barrier material, the vibration isolation performance of the retaining wall is optimized, and finally, efficient vibration isolation is achieved.

Description

technical field [0001] The invention relates to the technical field of vibration control of building structures, in particular to an efficient vibration isolation method for an underground precision laboratory. Background technique [0002] Underground or semi-underground precision, high-precision or ultra-precision laboratory structures have extremely strict vibration requirements, so it is necessary to establish and use an efficient vibration isolation method to meet the laboratory's strict micro-vibration demands and control needs. [0003] However, because the traditional underground precision laboratory has no vibration isolation, vibration reduction function or does not meet its strict vibration requirements, when there are environmental changes such as external soil deformation, consolidation, and settlement, it will disturb the precision laboratory, and even cause The precision laboratory fails, so it needs to be treated for vibration control. The current vibration ...

[0003] However, because the traditional underground precision laboratory has no vibration isolation, vibration reduction function or does not meet its strict vibration requirements, when there are environmental changes such as external soil deformation, consolidation, and settlement, it will disturb the precision laboratory, and even cause Precision lab fails, so it needs to be treated for vibration control

The current vibration control method is to carry out secondary vibration reduction construction for the underground laboratory, but the secondary vibration reduction construction will inevitably cause disturbance, modification or even damage to the existing building structure and surrounding soil, which will increase the difficulty of construction , increase costs, and may even cause safety hazards
