Abstract
Provided is a high-performance polyethylene double-wall corrugated pipe. The high-performance polyethylene double-wall corrugated pipe comprises a smooth polyethylene pipe basal body and a polyethylene corrugated pipe layer attached to the outer surface of the pipe basal body. A plurality of discontinuous reinforcing ribs are arranged at the axial trough positions of the corrugated pipe layer. By means of the structural design of the reinforcing ribs of a forming module of the polyethylene double-wall corrugated pipe, the reinforcing ribs are distributed symmetrically and discontinuously along the troughs in the axial direction of the pipe with one mould as a distribution cycle. Through improvement on the structural design of the reinforcing ribs, inner stress generated in the extrusion molding process of the polyethylene double-wall corrugated pipe can be eliminated, so that the ring stiffness, ring flexibility and impact performance of the pipe are improved.
Description
Technical field
The present invention relates to a kind of polyethylene double-wall corrugated pipe, be specifically related to a kind of high-performance polyethylene double-wall corrugated pipe.
Background technique
In recent years, the plastic pipe industry of China obtains development at a high speed, and application constantly expands, and has become one of industry important in national economy, has been described as the blood vessel in city, more and more receives the concern of governments at all levels and relevant departments.Meanwhile, national relevant policies guide and make plastic pipe obtain further genralrlization application.The associated documents such as " Tenth-Five Year Plan of national chemical building material industry and development planning outline in 2010 ", the Ministry of Construction " apply about the issue < Ministry of Construction and limit and prohibit the use the bulletin of technology > " (No. 218th, the Ministry of Construction) propose application and the developing goal of various plastic pipe.Polyethylene double-wall corrugated pipe, according to its excellent performance, is rapidly developed especially.
In structure due to traditional polytene corrugated tube, independently of one another, such structure is unfavorable for the adjustment of ripple intraductal pressure, also can affect the global stability of bellows, causes its working life too short for ripple tube layer outer surface and basal body pipe.The polytene corrugated tube in present market is in order to overcome the problem existing for conventional polyethylene bellows, the stiffening rib of Symmetrical Continuous Distribution is provided with at tubing outer surface of matrix, this to some extent solves the problem of conventional polyethylene bellows, but still there is the low problem of polytene corrugated tube ring stiffness, ring flexibility and impact property.
Summary of the invention
For above the deficiencies in the prior art, the invention provides a kind of high-performance polyethylene double-wall corrugated pipe.
A kind of high-performance polyethylene double-wall corrugated pipe, described high-performance polyethylene double-wall corrugated pipe comprises smooth polyvinyl piping materials matrix and is fitted in the polyethylene corrugated tube layer of tubing outer surface of matrix, and the axial trough place of described ripple tube layer is provided with several discontinuous stiffening rib.
Described several discontinuous stiffening rib is symmetrical.
Described several stiffening rib is cross structure.
Described stiffening rib is hollow-core construction.
Described stiffening rib communicates with the ripple struction inside of ripple tube layer.
The two ends of the part that described stiffening rib parallels with ripple tube layer are Open architecture.
The described same shaft orientation reinforcing rib being distributed in ripple tube layer trough place is spaced.
The described adjacent shaft orientation reinforcing rib being distributed in ripple tube layer trough place interlocks and arranges at equal intervals.
Described stiffening rib is period profile at ripple tube layer trough place.
Beneficial effect of the present invention is: the present invention is by carrying out structural design to the stiffening rib of polyethylene double-wall corrugated pipe forming module, and the trough place made it along tubing axis is symmetrical but discontinuously arranged, and with one piece of module for distribution period.By the improvement designed reinforcing rib structure, contribute to the internal stress that elimination polyethylene double-wall corrugated pipe produces in extruding and moulding process, thus the ring stiffness of raising tubing, ring are flexible and impact property.
Accompanying drawing explanation

Fig. 2 is the side structure schematic diagram of a kind of high-performance polyethylene double-wall corrugated pipe of the present invention;
In figure: 1 is tubing matrix; 2 is ripple tube layer; 3 is stiffening rib.
Embodiment
Illustrate below in conjunction with embodiment and accompanying drawing and the present invention is described in further details.
A kind of high-performance polyethylene double-wall corrugated pipe, described high-performance polyethylene double-wall corrugated pipe comprises smooth polyvinyl piping materials matrix (1) and is fitted in the polyethylene corrugated tube layer (2) of tubing matrix (1) outer surface, the axial trough place of described ripple tube layer (2) is provided with several symmetrical discontinuous stiffening ribs (3), and described stiffening rib (3) is period profile at ripple tube layer (2) trough place.The present invention is by carrying out structural design to the stiffening rib (3) of polyethylene double-wall corrugated pipe forming module, and the trough place made it along tubing axis is symmetrical but discontinuously arranged, and with one piece of module for distribution period.By the improvement to stiffening rib (3) structural design, contribute to the internal stress that elimination polyethylene double-wall corrugated pipe produces in extruding and moulding process, thus the ring stiffness of raising tubing, ring are flexible and impact property.
The described same shaft orientation reinforcing rib (3) being distributed in ripple tube layer (2) trough place is spaced, adjacent shaft orientation reinforcing rib (3) is staggered to be arranged at equal intervals, can greatly improve bellows resistance to compression, shock resistance like this.
Described several stiffening rib (3) is hollow cross structure, described stiffening rib (3) communicates with the ripple struction inside of ripple tube layer (2), and the two ends of the part that described stiffening rib (3) parallels with ripple tube layer (2) are Open architecture.The design of stiffening rib (3) this structure; the pressure in bellows is made to obtain balance; there will not be pressure skewness; cause the damage of ripple tube layer (2); and cross structure can be avoided because applying pressure on the invention excessive; cause the mutual extruding between ripple tube layer (2); and cross structure also can play the effect of buffering between ripple tube layer (2); be conducive to protection ripple tube layer (2), extend working life of the present invention.
Following technique effect can be realized: the present invention is by carrying out structural design to the stiffening rib (3) of polyethylene double-wall corrugated pipe forming module by the present invention, the trough place made it along tubing axis is symmetrical but discontinuously arranged, and with one piece of module for distribution period.By the improvement to stiffening rib (3) structural design, contribute to the internal stress that elimination polyethylene double-wall corrugated pipe produces in extruding and moulding process, thus the ring stiffness of raising tubing, ring are flexible and impact property.
