A hollow cavity is provided in the main pipe section 1 and the secondary pipe section 2.

[0026] The water seepage detection component 4 includes a water-absorbing block 41 disposed in the hollow cavity and located at the cone head 3 for absorbing water seeping from the pipe, and a connecting rod 42 disposed on the end face of the water-absorbing block 41 and extending vertically to the top of the hollow cavity inside the secondary pipe section 2 for vertically moving the water-absorbing block 41 to the outside.

[0027] The transmission mechanism 5 is located at the interface where the main pipe section 1 and the secondary pipe section 2 meet, and is used to drive the cone head 3 connected to the main pipe section 1 to perform a rotating operation in the soil layer.

[0028] In practice, the auxiliary pipe section 2, which is rotatably connected to the top of the main pipe section 1, and the cone 3 welded to the bottom of the main pipe section 1, can drive the main pipe section 1 to rotate under the power transmission of the transmission mechanism 5, and then realize the drilling of the soil layer at the designated point under the rotation of the tip of the cone 3.

[0029] The water leakage detection assembly 4 vertically installed in the hollow cavity communicated between the main pipe section 1 and the auxiliary pipe section 2, which comprises a water absorption block 41, can effectively absorb the water infiltrated therein. When the water absorption block 41 is pulled out by the connecting rod 42 vertically installed on the center of the water absorption block 41, the state of the water absorbed by the water absorption block 41 can be observed, and whether the pipeline laid in the soil layer of the specified area has a leakage point can be detected, thereby effectively improving the leakage detection efficiency of the pipeline.

[0030] Preferably, the top of the tapered head 3 is also provided with a detection probe for detecting soil humidity. In the actual detection process, multi-point detection can be performed in the specified area, and real-time feedback can be performed through the detection probe.

In this way, by arranging the buckle structure on the top frame 43 close to the end surface of the auxiliary pipe section 2, the auxiliary pipe section 2 can be detachably assembled. When assembled, the whole tool is convenient to use, and when separated, the water infiltration detection assembly 4 can be taken out from the hollow cavity of the main pipe section 1 and the auxiliary pipe section 2 for water infiltration observation, which is simple to operate.

[0039] The above only describes the preferred embodiments of the present application and is not intended to limit the present application.
