Detailed Description

Referring to fig. 1 to 4, in an embodiment of the present invention, a PVC pipe with strong toughness includes an outer pipe 1 and an inner pipe 2, the outer pipe 1 and the inner pipe 2 are both made of PVC material, the outer pipe 1 is sleeved on the outer side of the inner pipe 2, a reinforcing layer 3 is disposed between the outer pipe 1 and the inner pipe 2, an abrasion resistant layer 5 is disposed on the outer side of the outer pipe 1, a group of convex strips 4 is disposed on the inner side of the inner pipe 2, the convex strips 4 are distributed in a spiral state in a vertical direction, the distance between two adjacent convex strips 4 is equal, and a spiral steel wire 6 is disposed inside each convex strip 4.

In fig. 4: the wear-resistant layer 5 comprises a modified toughening resin layer 51, and wear-resistant ceramic particles 52 are uniformly distributed in the modified toughening resin layer 51.

By adopting the scheme, the modified toughening resin layer 51 cooperates with the wear-resistant ceramic particles 52, so that the wear resistance, high and low temperature resistance, water resistance and corrosion resistance of the PVC pipe are enhanced, and the toughness of the PVC pipe is further improved.

In fig. 1 and 2: the sand grip 4 is also the component of PVC material, and 8 are no less than to the quantity of sand grip 4, and the most advanced of sand grip 4 is towards the inboard of inner tube 2, and the flat end of sand grip 4 and the inner wall integrated into one piece of inner tube 2.

Through adopting above-mentioned scheme, all sand grips 4 all are the pipe wall department that the spiral state distributes at inner tube 2, can play the effect of direction to rivers to reduce the condition because of rivers collide the pipe wall of inner tube 2 and produce the noise, and when PVC pipe is whole to be buckled, sand grip 4 can play certain supporting role to the pipe wall of inner tube 2, thereby has further strengthened the holistic toughness of PVC pipe.

In fig. 1 and 2: the reinforced layer 3 is a galvanized steel wire mesh which is spirally wound outside the inner pipe 2.

By adopting the scheme, the inner pipe 2 can be conveniently wrapped by the galvanized steel wire mesh in the spiral state, and the galvanized steel wire mesh is strong in toughness and long in service life.

In fig. 3: the spiral steel wire 6 is a galvanized steel wire.

By adopting the scheme, the service life of the spiral steel wire 6 is prolonged.
