Detailed Description

The following will further describe a compression resistant MPP corrugated pipe according to the present invention with reference to the accompanying drawings.

Referring to fig. 1-3, the anti-pressure MPP corrugated pipe comprises a pipe body 1, wherein the pipe body 1 comprises an inner pipe 2 and an outer pipe 3, and the outer pipe 3 is provided with a wave crest 31 and a wave trough 32; the device is characterized by also comprising a buffer structure 4 arranged on the outer pipe 3 and an anti-extrusion structure 5 arranged at the port of the inner pipe 2; through the arrangement of the buffer structure 4, the impact on the pipeline body 1 is reduced, and the service life of the pipeline body 1 is prolonged; through the setting of anti extrusion structure 5, improve the anti extrusion performance of pipeline port department, avoid 1 port of pipeline body to lead to easily damaged because of extrusion or impact, improve pipeline body 1's life.

Further, the anti-extrusion structure 5 comprises a central block 51, a plurality of connecting plates 52 arranged along the axis of the central block 51 in an annular array, and a supporting plate 53 arranged on the connecting plates 52 and attached to the pipe wall of the inner pipe 2; through the setting of center block 51, play the supporting role to connecting plate 52, through the setting of a plurality of connecting plates 52, play the supporting role to backup pad 53, through the setting of backup pad 53, play the supporting role to inner tube 2, through setting up a plurality of connecting plates 52 along center block 51 axle center annular array to can form the support to intraductal whole port, improve the support stability, improve the anti extrusion performance of 1 port of pipeline body.

Further, the supporting plate 53 is arc-shaped, so that one side of the supporting plate 53 is completely attached to the pipe wall of the inner pipe 2, the contact area between the supporting plate 53 and the pipe wall of the inner pipe 2 is increased, the supporting effect is improved, and the anti-extrusion capacity is improved.

Furthermore, a through hole 33 is arranged in the wave crest 31, and a cushion pad 34 is filled in the through hole 33; through filling the blotter 34 in through-hole 33, when outer pipe 3 crest 31 received the extrusion, form the buffering to extrusion and impact through blotter 34, avoid directly forming the impact to inner tube 2, avoid inner tube 2 to receive the impact and produce the damage.

Further, the through hole 33 has a circular cross section. Through setting up through-hole 33 to circular, circular compare with shape such as rectangle, its anti extrusion ability is stronger, can disperse the extrusion force that receives on whole circle, avoid the stress point to concentrate to improve shouldering extrusion and shouldering impact ability.

In the utility model, after the pipeline body 1 is manufactured, the anti-extrusion structures 5 are installed at the two end openings of the pipeline, the support plate 53 is aligned with the orifice of the inner pipe 2 during installation, the central block 51 is pushed, the central block 51 drives the connecting plate 52 and the support plate 53 to move towards the inside of the pipe body, the support plate 53 is tightly matched with the pipe wall of the inner pipe 2, the pipe is prevented from being easily separated, the installation is simple and convenient, the disassembly and the assembly are convenient, and the pipe can be disassembled only by pulling the pipe outwards.

The scope of protection of the utility model is not limited to the above embodiments and variations thereof. The present invention is not limited to the above embodiments, but may be modified in various ways.
