Abstract

A reinforced high-density polyethylene double-walled corrugated pipe comprises a smooth polyethylene pipe base and a polyethylene corrugated pipe layer attached to the outer surface of the pipe base. Two axial reinforcing ribs are symmetrically arranged on the outer surface of the pipe base and penetrate through a corrugated structure of the corrugated pipe layer. The reinforced high-density polyethylene double-walled corrugated pipe is simple in structure, high in strength, small in friction resistance due to the smooth inner wall and large in flow volume, the stability of the corrugated pipe layer is high, and the service life of the integral pipe is prolonged.

Description

A kind of reinforced high-density polyethylene double-wall corrugated pipe

Technical field

The utility model relates to tubing, is specially a kind of reinforced high-density polyethylene double-wall corrugated pipe that is provided with stiffening rib.

Background technique

Under ground piping is an indispensable big event in the engineerings such as municipal engineering, environmental protection, agricultural drainage and irrigation, industrial construction, the past subterranean pipe line mostly adopts concrete pipe, cement pipe or cast iron tube, because concrete pipe and cement pipe exist inner tube wall coarse, current, threading resistance cause water velocity slowly, easily to be detained dirt or threading difficulty greatly; Cast iron tube then rotproofness is relatively poor, tubing weight is big, higher to managing basic stability requirement, the easy leakage pollution edatope of jointing etc., generally adopted plastic pipe now, and high-density polyethylene double-wall corrugated pipe is also classified one of first-selected tubing as, but in the structure of traditional high-density polyethylene double-wall corrugated pipe, its surperficial bellows is independent of each other, this structure is unfavorable for the adjustment of ripple intraductal pressure, also therefore have influence on high-density polyethylene double-wall corrugated pipe global stability, cause its working life too short.

The model utility content

The technical problem that the utility model solved is to provide a kind of reinforced high-density polyethylene double-wall corrugated pipe, to solve the shortcoming in the above-mentioned background technology.

The technical problem that the utility model solved realizes by the following technical solutions:

A kind of reinforced high-density polyethylene double-wall corrugated pipe, comprise smooth polyvinyl piping materials matrix and the polytene corrugated tube layer that is fitted in the tubing outer surface of matrix, it is characterized in that, described tubing outer surface of matrix is symmetrically arranged with two axial stiffening ribs, and described stiffening rib runs through the ripple struction of bellows layer.

In the utility model, described stiffening rib inner hollow, and communicate with the ripple struction inside of bellows layer.

The utility model is the hollow ring structure-wall pipe material, as a kind of novel light tubing, have in light weight, proof to external pressure, sanitation performance is good, construction is fast, advantages such as long service life, the while stable chemical performance, has excellent electric insulating, ageing-resistant strong with the ESCR ability, the Applicable temperature scope is wide, and has good comprehensive mechanical performance, bearing capacity is strong, the integration engineering cost has more advantage, at no pressure water, substantial contribution and engineering time can be saved for the user in blowdown and telecommunication cable engineering field, are the conventional concrete pipes, the desirable substitute products of cement pipe and cast iron tube.

And the stiffening rib that designs in the utility model, by realizing communicating of bellows layer ripple struction inner air, balance the pressure of bellows layer inside, solved because the difficult problem of expanding with heat and contract with cold and causing the bellows layer to damage easily, strengthened the stability of tubing greatly.

Beneficial effect:

The utility model is simple in structure, the intensity height, and resistance to compression is shock-resistant, inner wall smooth, surface friction drag is little, and inflow-rate of water turbine is big; Bellows layer stability is strong, has prolonged the working life of whole tubing.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1, Fig. 2, a kind of reinforced high-density polyethylene double-wall corrugated pipe, comprise smooth polyvinyl piping materials matrix 1 and the polytene corrugated tube layer 2 that is fitted in tubing matrix 1 outer surface, it is characterized in that, described tubing matrix 1 outer surface is symmetrically arranged with two axial stiffening ribs 3, and described stiffening rib 3 runs through the ripple struction of bellows layer 2.Described stiffening rib 3 inner hollow, and communicate with the ripple struction inside of bellows layer 2, this structure is by realizing communicating of bellows layer 2 ripple struction inner air, balance the pressure of bellows layer 2 inside, solve difficult problems that cause bellows layer 2 to damage easily owing to expanding with heat and contract with cold, strengthened the stability of tubing greatly.

More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
