According to the principle that an air compressor blows water after a water heating pipe is pressed, the embedded pipe is a narrow space with two open ends, high pressure is input after one end of the embedded pipe is closed, and fillers such as water, impurities and the like in the pipe are output from the other end under the action of pressure airflow. The same principle is used for stringing the electric wire tube, one end of the stringing rope is placed, and the stringing rope can be completed under the action of pressure.
The front section of the air compressor is connected with a gas storage device refitted from a fire extinguisher, and a rope is tied with a sponge or a foam block to be plugged at the end part of the gas outlet to form a closed system. After the switch valve of the gas storage device is opened by utilizing the pressure generated by the air compressor, the gas in the gas storage tank is released instantly from the large-to-small diameter outlet, the reserved line pipe can be filled with the gas instantly, and the threading rope is brought to the other end of the line pipe instantly.
Constructor carries out the reeving according to the pre-buried threading pipe of drawing, and when the reeving annulate was carried out, for guaranteeing that the reeving smoothly passes through the threading pipe along with the air current, set up a wire ring at PVC pipe front end 100mm department trompil as the leading-in end of nylon rope. The nylon stringing rope is not knotted and can smoothly enter the PVC pipe.
After the rope threading and the end part binding sponge penetrate through the embedded line pipe, the rope threading anti-reverse effect is automatically formed at the tail end, the construction length is reserved for leading in the end rope, and the construction method is completed after the sponge is bound.
Has the advantages that:
