[0040] The method for using the basalt fiber panel concrete rockfill dam with the anti-crack mechanism: initially, the glass tube 4 is fixed at both ends of the unit plate 3. When the deformation of a certain unit plate 3 due to settlement or long service time is sufficient to break the glass tube 4, that is, the unit plate 3 is in a critical condition of cracking, at this time, the salt solution in the glass tube 4 flows out and mixes with pure water, so that the first conductive rod 6 is connected with the second conductive rod 7 through the mixed solution, so that the laser head 8 at the center of the unit plate 3 is energized to work. At this time, the inductive switch 28 on the spraying unit at the corresponding position on the dam body 1 is triggered, and then the signal is transmitted to the control room. The operator determines whether to trigger the spraying unit to work according to the actual situation on site;

[0041] When the operator triggers the spraying unit to work, that is, the inductive switch 28 is triggered, the push rod 12 works, the push plate 14 is pressed and slides in the storage tank 11, and the glue in the storage tank 11 is pressed and sprayed out through the extrusion hole 21 and the spraying hole 22. At the same time, the rotation of the lead screw 13 drives the nozzle 9 to rotate synchronously, so that the spraying hole 22 diverges and sprays with the nozzle 9, realizing large-area spraying of the unit plate, so as to repair the surface cracks;

[0042] After repair, the operator can assign workers to replace the detection unit of the repaired unit plate in its entirety, and adjust the fixed length of the glass tube 4 through the second positioning seat 25, so as to facilitate detection next time.
