Abstract: Sensors are needed on site to monitor the safety of water conservancy and hydropower projects.As well,cables are laid to monitoring stations to collect data.Specific installation structures are re- quired for monitoring sensors inside the building,and the centralized cables may exert certain impact on the project.This paper introduces the methods for cable connection,laying and protection,explores the layout and management of piezometer tubes for foundation of concrete dams,studies the installation structure of monitoring sensors for shield tunnels,proposes optimization measures,and proposes the use of horizontal and vertical waterproof cables for key parts of pumped storage power stations with ultra- high water pressure which can substantially reduce the potential risks caused by safety monitoring devices to hydraulic structures.The relevant experience has been successfully verified in practice and can be used as a reference for similar projects.

Key words: safety monitoring, potential risk, structural integrity, concentrated seepage, confined space
