Embodiment 1
[0039] Such as figure 1 As shown, a karst tunnel water exploration device of the present invention includes a drill pipe 1 and a drill bit 2. The drill bit 2 is connected to one end of the drill pipe 1, and the end of the drill pipe 1 close to the drill bit 2 is provided with an annular groove 3 and an annular groove A number of infrared cameras 4 are evenly arranged on the bottom surface, and an annular movable sealing plate 5 is arranged in the annular groove 3 above the infrared camera 4.
[0040] Further, the side wall of the annular groove 3 close to the drill bit 2 is provided with an annular groove 31, and the other side wall is provided with an annular limiting groove 32, the annular groove 3, the annular groove 31 And the axis of the annular limit groove 32 are coincident with the axis of the drill rod 1, one end of the movable sealing plate 5 is placed in the annular limit groove 32, and the other end is placed in the annular clamping groove 31, and the annular limit gro...
Embodiment 2
[0044] Such as figure 1 As shown, on the basis of Embodiment 1, this embodiment also includes the following technical features:
[0045] The length of the strip chute 6 is the same as the length of the annular limit groove 32, the top of the slider 61 is connected with a handle 62, and a positioning member is arranged between the slider 61 and the strip chute 6.
[0046] Further, the thickness of the annular retaining groove 31 and the annular limiting groove 32 is the same as the thickness of the movable sealing plate 5, and the distance between the annular retaining groove 31 and the annular limiting groove 32 is the same from the axis of the drill rod 1. The distance between the surface and the outer surface of the drill rod 1 is 1-3 mm.
[0047] Further, there are protrusions all over the periphery of the drill rod 1, and both the drill rod 1 and the movable sealing plate 5 are made of wear-resistant metal materials.
[0048] Further, the number of the infrared camera 4 is 3-5, th...
Embodiment 3
[0050] The cavern in this embodiment is a certain distance from the tunnel line, such as figure 2 As shown, a construction method for blocking water in a karst tunnel includes the following steps:
[0051] (1) Connect the drill pipe 1 of the karst tunnel water exploration device described in embodiment 1 or 2 with a motor to form a drilling machine;
[0052] (2) Use a drilling machine to drill a water detection hole 8 on the side wall of the tunnel 7. After the front end of the water detection hole 8 has water, continue to drill 10-20cm forward until the annular groove 3 is placed in the karst pipeline 9. Pull the handle 62 on the drill pipe 1 backwards to make the movable sealing plate 5 completely slide into the annular limit groove 32, the infrared camera 4 is exposed to the karst pipeline 9, and multiple infrared cameras 4 collect images in the karst pipeline 9 in all directions. Send the collected images of the karst pipeline 9 to the control terminal;
[0053] (3) The operato...
