Description

Technical Field

[0001] This utility model belongs to the field of building vibration and noise control technology and basement foundation and exterior wall waterproofing control technology, specifically involving a high load-bearing capacity waterproof composite vibration damping pad structure. Background Technology

[0002] With the rapid development of urban rail transit, on the one hand, it has brought great convenience to people's travel; on the other hand, with the dense development of rail transit lines and people's increasing attention to the environment, vibrations from transportation facilities and other environmental factors have had a significant impact on sensitive buildings within a certain range. To address the adverse effects of environmental vibrations and groundwater on sensitive buildings, vibration control is necessary to reduce its negative impact on people's normal work and life, keeping it below the limits required by regulations or at an even better level.

[0003] Existing building vibration damping pads on the market have limited load-bearing capacity and cannot withstand large upper loads, making them unsuitable for foundation vibration damping of higher floors. Furthermore, traditional vibration damping pads lack complete waterproofing capabilities, requiring separate layers for waterproofing and vibration damping layers on the building foundation and basement exterior walls. This necessitates 2-3 construction steps on-site, significantly increasing the construction period and difficulty. Moreover, the layered construction of waterproofing and vibration damping layers presents many hidden drawbacks. Therefore, it is necessary to improve upon these issues. Utility Model Content
