the square protective layer, the body with square protective layer passes through double-deck pipe machine mould integrated into one piece, square protective layer is used for the body plays the effect of preapring for an unfavorable turn of events when being extruded, the mounting groove has been seted up to square protective layer, install in the mounting groove and be used for strengthening the extruded metal frame in hole, two the metal frame is square the setting and is in the mounting groove.
Preferably, one end of the pipe body is coated with a PE composite layer, and the PE composite layer is attached to a cross section of the one end of the pipe body in an annular shape.
Preferably, be the equidistance array in the body and be equipped with the notch, every all install the strengthening rib in the notch.
Preferably, the notches and the reinforcing ribs are all arranged in an isosceles trapezoid shape.
Preferably, the distance from the reinforcing rib to the inner wall of the pipe body is greater than the distance from the reinforcing rib to the outer side wall of the pipe body.
Preferably, the width of the cross section of the square protective layer on the outer surface of the pipe body is smaller than the width of the cross section of the reinforcing ribs.
Compared with the prior art, the utility model has the beneficial effects that:
1. the one end of keeping away from the PE composite bed with the body is passed through the hot melt machine heating and is connected outside polyethylene feed pipe one end, places in bilge well lateral wall department through square protection for bear the weight of the used brick of bilge well through square protective layer, simultaneously because have two metal frames side by side in the square protective layer, can increase the bearing of square protective layer, square protective layer is square setting simultaneously, and the brick cross-section of the bilge well of current doing is square setting, consequently can reach better sealing performance.
2. Because square protective layer sets up in bilge well lateral wall department for square protective layer all scribbles the PE composite bed to polyethylene high pipe one end department setting in the well to its surface of the one end that the body is in the well simultaneously and the cross-section, makes and effectively plays prevention of seepage, acid and alkali-resistance, corrosion-resistant effect, prevents that the body from receiving the environmental damage under the bilge well for a long time.
