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...
