After reaching the position, connect the nozzle and connecting rod with bolts on the fixed plate, and fix the suction head of the mud vacuum pump On the side of the fixed plate close to the nozzle, the suction head is lower than the nozzle and the geotextile nozzle. At the same time, the liquid storage tank of the high-pressure water jet cutting device is connected to the external water supply equipment with a water-filled pipe; after the connection is completed, fix the third electric telescopic Rod height, adjust the height of the first electric telescopic rod and the second electric telescopic rod so that the nozzle is 30-50mm away from the slope surface, and the lower end nozzle of the geotextile nozzle is 20-30mm away from the broken surface;

Step S4: Control the advancement of the equipment used to lay plastic geotextiles. At the same time, open the valve of the high-pressure water jet cutting device and the melt valve of the geotextile laying device to start construction. At the same time, turn on the mud vacuum pump; the high-pressure water jet cutting device is used to cut soil. A gap is formed on the side slope, and the geotextile laying device is used to inject molten plastic geotextile into the gap formed by cutting;

During operation, the reflective photoelectric sensor detects the distance between the slope and the nozzle. When the distance is less than 30mm, the first electric telescopic rod is controlled to rise, thereby raising the height of the nozzle so that the distance between it and the slope is greater than 30mm;

At the same time, according to the moving speed V of the equipment used to lay the plastic geotextile, the distance L between the nozzle and the geotextile nozzle, the time T is calculated, and the second electric telescopic rod is controlled to execute the same function as the first electric telescopic rod after the time T has passed. same action;

The calculation process of time T is:

Step S5: When the equipment used to lay the plastic geotextile reaches the predetermined end point, control the equipment used to lay the plastic geotextile to stop moving forward, and at the same time close the valve of the high-pressure water jet cutting device and the melt valve of the geotextile laying device. mud vacuum pump;

Step S6: After the water in the nozzle and the remaining melt in the geotextile nozzle flow out naturally, if there is remaining in the melt storage box, open the melt valve and control the second electric telescopic rod to rise through the receiving device Place it under the geotextile nozzle to collect the excess melt and transport it away;

Step S7: After the nozzle under the geotextile nozzle has cooled down, disassemble the fixed plate, nozzle and connecting rod in sequence, then disassemble the slide rail, and finally remove the main body of the equipment used for laying plastic geotextile and the slide rail support device , construction is completed.
