[0002] In the field of water conservancy engineering, the safe operation of dams is the key to ensuring the rational use of water resources and flood prevention and disaster reduction. With the development of engineering technology, concrete face rockfill dams, as a new type of structure that combines traditional rockfill dams with modern concrete face technology, are widely used due to their high economy and adaptability. In the design of this type of dam, the design and application of anti-seepage drainage pipe network system has become one of the important technical means to ensure the safe and stable operation of the dam.

[0003] The concrete face rockfill dam combines the flexibility of the rockfill dam and the tightness of the concrete dam. It has good anti-seepage performance and adaptability, and can effectively cope with complex and changeable geological and hydrological conditions. However, no dam system can completely avoid the existence of seepage problems. Especially under extreme climate and complex geological conditions, the seepage problem will cause damage to the dam structure and even threaten the safety of the dam. Therefore, it is particularly necessary to design a seepage monitoring system for rockfill dams. However, the existing seepage monitoring system for concrete face rockfill dams has the problem of insufficient leakage monitoring. Utility Model Content

[0018] The specific implementation modes of the present invention are described below to facilitate the understanding of the present invention by those skilled in the art. However, it should be clear that the present invention is not limited to the scope of the specific implementation modes. For those skilled in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, these changes are obvious, and all inventions and creations utilizing the concept of the present invention are protected.

[0019] like Figure 1 As shown, a rockfill dam seepage monitoring system includes a water collection pipe network unit and a water tank with a sensor alarm unit arranged inside.

The water collection pipe network unit includes a longitudinal pipe 4 and a vertical pipe 5 along the rockfill dam.

[0021] In an optional embodiment of the present invention, the water collection pipe network unit is arranged in the cushion layer area 3 of the rockfill dam on one side close to the concrete panel 2; the water collection pipe network unit is provided with a tracer placement area.

[0022] The water collection pipe network unit includes at least one vertical pipe 5 and a longitudinal pipe 4 along the rockfill dam; one end of the vertical pipe is provided with a tracer placement area, and the other end of the vertical pipe is connected with the longitudinal pipe 4 along the rockfill dam; one end of the longitudinal pipe 4 along the rockfill dam is provided as a closed port, and the other end of the longitudinal pipe 4 along the rockfill dam is provided as a water outlet.

[0023] A tracer placement area is provided at one end of the vertical pipe 4. Different tracers are placed in the tracer placement area of ​​each vertical pipe 4. The tracer enters the water tank along with the seepage.

[0024] One end of the vertical pipe 5 where the tracer placement area is arranged is 0.5-1 m higher than the concrete panel to ensure that water does not enter the vertical pipe from the top of the pipe.

[0025] The longitudinal pipeline 4 of the rockfill dam is provided with a gradually increasing slope from the water outlet to the closed port, and the slope is not less than 0.3%, so as to facilitate the discharge of seepage from the water outlet.
