Embodiment Construction

[0013] The internal deformation monitoring method of the high earth-rock dam of the present invention is to set monitoring devices at different sections and different elevations in the high earth-rock dam, such as figure 1 Monitoring corridors 4, 5 are shown.

[0014] The monitoring device is a prestressed prefabricated corridor, such as Figure 2 ~ Figure 3 As shown, and install deformation monitoring instruments 9 and 10 in sections in the corridor (deformation monitoring instruments are existing equipment), such as Figure 4 shown.

[0015] The length of each section of the prefabricated corridor is about 2.0m, and the space between the prefabricated corridors is filled with flexible material 8 (geomembrane or asphalt, etc.) to adapt to the uneven settlement of the rockfill dam.

[0016] The internal monitoring instruments of the rockfill body are drilled from the monitoring corridor to make the internal monitoring arrangement of the rockfill body more operable and reason...

Abstract

The invention discloses an inner deformation monitoring method and device for a high earth-rock dam. The method is characterized in that a monitoring device is arranged on different sections and different elevations in the high earth-rock dam. The monitoring device is a prestress prefabricating gallery, and a deformation monitoring instrument is arranged in the gallery in a segmented mode; the length of each section of the prefabricating gallery is 2.0m; and flexible material is filled between sections of prefabricating gallery. According to the invention, the problems of the adaptability and the reliability of a long-distance deformation monitoring instrument are solved, and meanwhile, the problems that the cable of the monitoring instrument in the earth-rock dam is overlong and is difficult to protect are solved according to the arrangement of the monitoring gallery, thereby being more convenient for manual inspection and examination.

Description

technical field [0001] The invention relates to the technical field of hydropower engineering, in particular to a method and device for monitoring internal deformation of a high earth-rock dam. Background technique [0002] In recent years, domestic hydropower technology has developed rapidly, represented by Tianshengqiao Class I (dam height 178m), Hongjiadu (dam height 179.5m), Sanbanxi (dam height 185.5m) and Shuibuya (dam height 233m) hydropower stations, etc. A number of typical projects have gradually increased the height of concrete face rockfill dams from 100m to 200m, making the design theory and construction technology of earth-rockfill dams in my country reach the international advanced level. However, the development of safety monitoring technology for face rockfill dams obviously lags behind the development of dam construction technology, and the adaptability, durability, and impact resistance of many monitoring instruments still remain at the level of 100m dam he...
