Problems solved by technology
Since the high dam venting system is a large-scale engineering project, the operation of the high dam venting system is greatly affected by the water pressure from the upstream. Once the upstream water pressure exceeds the rated limit, it will affect the safe and stable operation of the high dam venting system, resulting in Huge economic losses. However, there is no clear standard basis for the operation of the high dam venting system at present. The venting operation method of the high dam venting system urgently needs a complete monitoring system to track and evaluate its safe operation status, and Record and predict various problems in the operation of the project, provide a basis for the improvement and development of the technology, and provide a reference for the monitoring design of the project

Embodiment Construction
[0026] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but the scope of protection is not limited to the description.
[0027] The invention provides a high dam emptying system building structure monitoring system, such as Figure 1 to Figure 8 shown, including:
[0028] A tunnel 5 is excavated along the way of water discharge, and a concrete lining layer 505 is poured on the inner wall of the tunnel 5. A high dam venting system 26 is arranged above the tunnel 5. The cross sections of several tunnels 5 are selected as monitoring points. Corresponding monitoring instruments are installed at each monitoring point to obtain the structural state information of the building at the monitoring point.
[0029] Adopting the technical solution of the present invention, the high dam venting system adopts a plurality of primary gate devices and secondary gate devices to effectively share the head pressure from the ...

The invention discloses a building structure monitoring system of a high dam blowdown system. According to the building structure monitoring system, a tunnel is excavated along the bottom of a riverway, a concrete lining layer is cast on the inner wall of the tunnel. The high dam blowdown system is arranged on the tunnel, a plurality of cross sections of the tunnel are selected as monitoring points, a corresponding monitoring instrument is mounted at each monitoring point, and state information data on a building structure are acquired regularly. According to the technical scheme, the proper monitoring points are selected in the high dam blowdown system, the suitable monitoring instruments are mounted, the building structure deformation condition and other factors in the operation processof the high dam blowdown system are monitored in real time, whether the high dam blowdown system should be overhauled or not is judged according to the monitoring result, and the safety and stabilityof the building structure of the high dam blowdown system are effectively guaranteed.
Description
technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, and in particular relates to a building structure monitoring system for a high dam venting system. Background technique [0002] With the development of dam engineering technology and the emergence of 300m high dams, higher requirements are put forward for the venting and operation of the project. As the high dam venting system is a large-scale engineering project, the operation of the high dam venting system is greatly affected by the water pressure from the upstream. Once the upstream water pressure exceeds the rated limit, it will affect the safe and stable operation of the high dam venting system, resulting in Huge economic loss. However, there is no clear standard basis for the operation of the high dam venting system at present. The venting operation method of the high dam venting system urgently needs a complete monitoring system to track and evaluate i...
