Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drainage and prevention, and in particular to a foundation pier drainage and prevention structure and an earthquake monitoring system. Background Art
[0002] Earthquake monitoring technology is crucial for understanding earthquake mechanisms, assessing potential earthquake risks, and implementing effective earthquake emergency responses. Currently, to ensure the accuracy and reliability of earthquake monitoring data, seismic instruments are typically installed on specially designed piers to reduce the impact of surface rock and soil structural differences on monitoring data. Traditional pier designs require a secure connection to the underlying bedrock or other more stable soil layers. Furthermore, to improve the monitoring quality of seismic instruments, piers are typically surrounded by seismic isolation trenches. Currently, most seismic monitoring pier designs rely primarily on passive waterproofing measures, such as sealants and waterstops, to prevent groundwater infiltration. However, in areas with high groundwater levels or complex geological conditions, this single drainage measure often fails to effectively cope with sustained groundwater pressure. In the event of severe water seepage, the reliability of the pier drainage system cannot be guaranteed, thus affecting the stability of the pier and the normal operation of the seismic instruments mounted thereon. To ensure the long-term stable operation of seismic instruments, we propose a pier drainage structure and earthquake monitoring system. Utility Model Content

[0023] The pier anti-drainage structure provided in this embodiment can prevent bedrock water from seeping into the ground layer through the first waterproof layer 400 of the waterproof component.
