Further, the base layer is made of PVC or PE or PET or PP or PC.

The utility model has the following beneficial effects:

1. when the sealing sleeve is used, the connection between the corrugated pipe body and the connector is realized by rotating the connecting sleeve, after the connection, a worker injects water into the sealing groove through the water injection hole, so that the expansion water stop ring expands to squeeze the sealing ring, sealing connection between the connecting sleeve and the corrugated pipe body is realized, meanwhile, because of the special trapezoid arrangement of the sealing ring, in the circulation process of a high-pressure position, the contact between the sealing ring and the inner wall of the sealing groove is further realized by the force generated by high pressure, and the effective anti-overflow leakage is realized.

2. When the corrugated hose is used, the tension resistance of the whole device can be improved through the arrangement of the fabric net layer, and the problem that the corrugated hose body is cracked due to high-pressure extrusion can be effectively avoided, so that the service life of the corrugated hose is prolonged.
