When the drill 202 drills into the top plate for a certain distance, the operation is stopped, the pressurizing driving piece 1041 is started, high-pressure water flow reaches the inside of the abrasive adding piece 105 through the water outlet pipe 1043, the storage cavity 1051 is driven to move through the abrasive input into the water outlet pipe 1043 by the control pipe 1052, the water flow wrapped with the abrasive can reach the inside of the water supply pipe 1064 through the water outlet pipe 1043, the initially unclosed one-way plate 10649 is pressed to the bottom surface of the annular cavity 10647 under the extrusion of the water flow, the sealing of the feeding hopper 10645 is realized, the water flow reaching the top of the water supply pipe 1064 is discharged into the inside of the cutting pipe cavity 305 through the through hole, the water flow entering the inside of the cutting pipe cavity 305 enters the inside of the driving sleeve 3052 through the water inlet pipe 30521, the driving sleeve 3052 is expanded to push the ring contact plate 30531 and the push rod 3053 upwards, so that the telescopic spray head 306 is driven to move outwards from the inside of the flow cutting cavity 305, the telescopic spray head 306 moves outwards to drive the ring inserting block 30324 to move outwards through the ring vertical plate 3063 and the clamping cavity 3064, the inner grinding ring plate 30322 is pulled out from the outer cavity 3023, the driven vertical plate 30321 of the rotating sleeve 303 is pulled out from the inside of the adjacent driving vertical plate 30221 by the outer movement of the ring inserting block 30324, the rotating sleeve 303 is always positioned on the outer side of the nozzle 3062, and when water flow in the flow cutting cavity 305 is discharged through the nozzle 3062, the diffused water flow is blocked and flows back to the inside of the extruding block 30323, so that soft soil layer collapse caused by the diffused water flow is reduced;
In order to prevent water from flowing into the storage chamber 1051, a check valve is provided in the control tube 1052.
After the telescopic nozzle 306 is clamped by the ring vertical plate 3063 and the clamping cavity 3064 to drive the ring inserting block 30324 and the rotary sleeve 303 to move, the rotary driving piece 10323 is continuously started, so that the rotary driving piece 10323 drives the flat driving piece 301 to continuously rotate, the flat driving piece 301 drives the vertical driving piece 302 to rotate, and when the vertical driving piece 302 rotates, the driving vertical plate 30221 outside the outer hollow pipe 3022 drives the driven vertical plate 30321 to rotate, so that the rotary sleeve 303 rotates along with the vertical driving piece 302, and the rotary sleeve 303 rotates in the clamping cavity 3064 through a circular ring at the bottom of the ring inserting block 30324, so that the telescopic nozzle 306 is not driven to rotate;
When the rotary sleeve 303 rotates, the soft soil layer is drilled through the grinding block 3031, so that soft soil between the nozzle 3062 and the rotary sleeve 303 is pushed into the outer cavity 3023, and along with the drilling of the rotary sleeve 303 and the jet flow of the nozzle 3062, the inner wall of the drilled hole can be drilled and cut more efficiently;
the rotary sleeve 303 is continuously drilled to obtain a space along with the soil at the front end of the rotary sleeve 303 and the driving sleeve 3052 is continuously expanded, so that the rotary sleeve 303 follows the telescopic nozzle 306 to enter the soft soil layer, collapse caused by the fact that the soft soil layer near the hole wall is excessively diffused by water flow is reduced, and along with the rotary sleeve 303 and the telescopic nozzle 306 entering the soft soil layer, the distance from the water flow nozzle 3062 to the soil layer is reduced, and therefore the impact force of water flow is further ensured;
It should be noted that, if the drilling of the rotary sleeve 303 and the grinding block 3031 is only aimed at drilling holes located on a soft soil layer, if the tight adhesion effect between the rotary sleeve 303 and the soil layer is to be improved, the rotary sleeve 303 and the soil layer may be optionally divided into two sections according to the positions of the water inlet pipe 30521 and the telescopic nozzle 306, the two sections may be sealed and separated (not shown), and the drive sleeve 3052 is connected with the pipe cutting chamber 305 connected with the telescopic nozzle 306 in a conducting manner (not shown), so that the pipe cutting chamber 305 connected with one section of the water inlet pipe 30521 is in butt joint with the sealing space of the inner limiting block 3041, so that water can only pass through the pipe cutting chamber 305 connected with the inner limiting block 3041 and then pass through the water inlet pipe 30521 to reach the inside of the drive sleeve 3052, after the drive sleeve 3052 is fully expanded, the drive sleeve 3052 is connected with the protective element 3052, namely the pressure release valve, and water is supplied to the inside the pipe cutting chamber 305 connected with the telescopic nozzle 306, thereby preferentially ensuring that the drive sleeve 3052 is expanded to drive the telescopic nozzle 306 and the rotary sleeve 303 to move outwards, so that the rotary sleeve 303 is convenient to be tightly adhered to the soil layer.
