Description
Technical field
The utility model belongs to plastic pipe technical field, and in particular to it is circular that a kind of outer wall wave crest, which is square inner wall,
HDPE plastic double-wall corrugated pipe.
Background technique
HDPE full name in English: " High Density Polyethylene ", Chinese is high density polyethylene (HDPE), is one
Kind of crystallinity is high, nonpolar thermoplastic resin, is that plastic tube made of raw material has that connection is reliable, low temperature impact HDPE
Hitting property is good, anti-stress cracking is good, chemical corrosion resistance is good, ageing-resistant performance is good, wearability is good, good toughness, high pressure resistant and make
With the service life it is long the advantages that.The HDPE plastic pipe tubing traditional with coating steel pipe etc. with cast iron pipe is compared, and has light-weight, corrosion resistant
Erosion, small flow resistance is energy saving, and simple installation is rapid, and the more low significant advantage of cost receives the happiness of pipeline engineering circle
Love, and gradually replace traditional piping material.
Since the plastic tube wall of single layer tube wall is thin easily-deformable, it is not suitable for buried construction environment, by continuous complete
It is kind, gradually produce the relatively good double-wall corrugated pipe of performance.Currently, double-wall corrugated pipe majority in the market is gathered by high density
Ethylene is primary raw material through extrusion molding, inner wall smooth, outer wall ripple, is hollow shape structure between inside and outside wall, what is also had is double
Wall ripple pipe outer wall is only combined at trough with inner layer wall, and the outer wall at wave crest is discontiguous with inner wall.It is above-mentioned double-wall corrugated
When pipe is squeezed in buried or transportational process by external force, outer wall is easily crushed at wave crest, ring stiffness and ring flexibility compared with
It is low.In addition, existing double-wall corrugated pipe outer wall is circle, in use, circular outer wall is easy the stubborn strength of rolling and is not easy to manage
Road positioning.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of rectangular double-wall corrugated pipes of plastics, have ectonexine knot
Structure combines compact, the ring stiffness and ring flexibility height of tubing, the good advantage of anti-pull ability.
In order to solve the above technical problems, the utility model takes following technical scheme:
A kind of rectangular double-wall corrugated pipe of plastics, comprising: inner and outer wall, the inner wall are circular inner wall, the outer wall packet
Outer wall wave crest and outer wall trough are included,
The outer wall wave crest be it is rectangular, the outer wall trough and the circular inner wall converge into one；
Connection rib, the axis of the connection rib and the circular inner wall are provided between the outer wall and the circular inner wall
It is arranged in parallel, the connection rib is located at the middle part of four sides of the outer wall.
Preferably, four apex angles of the outer wall wave crest are set as fillet.
Preferably, the connection rib protrudes the outer surface of the outer wall trough.
Preferably, the rectangular double-wall corrugated pipe of the plastics passes through extrusion molding mode disposal molding.
Compared with prior art, the utility model has the beneficial effects that
Connection rib is provided between outer wall and circular inner wall, the axis of connection rib and the circular inner wall is arranged in parallel, even
Rib radially links together outer wall wave crest and inner wall, so that the ring stiffness of tubing increases, and connects rib in axial direction
On by adjacent Wave crest and wave trough series combination together so that the ring flexibility of tubing is remarkably reinforced, and connection rib is respectively set
In the middle part of four sides of outer wall, is conducive to increasing ring stiffness and ring flexibility while the meter Chong for minimizing tubing, saves material
Material.

Specific embodiment
Technical solutions of the utility model are described in detail in the following with reference to the drawings and specific embodiments, with further
Understand the purpose of this utility model, scheme and effect, but is not intended as the limit of the appended claims for the utility model protection scope
System.
As depicted in figs. 1 and 2, the rectangular double-wall corrugated pipe of plastics, comprising: inner and outer wall 11, inner wall are circular inner wall 12,
Outer wall 11 includes outer wall wave crest 111 and outer wall trough 112, and outer wall wave crest 111 is rectangular, outer wall trough 112 and circular inner wall 12
Converge into one；
Connection rib 13 is provided between outer wall 11 and circular inner wall 12, rib 13 is parallel with the axis of circular inner wall 12 sets for connection
It sets, connection rib 13 is located at the middle part of four sides of outer wall 11.
It sets rectangular for the wave crest 111 of outer wall 11, rolling, rolling is less prone to after being placed into construction location in construction
Phenomena such as twisting strength.
It is provided with connection rib 13 between outer wall 11 and circular inner wall 12, connects rib 13 radially by 111 He of outer wall wave crest
Circular inner wall 12 links together, ectonexine structure combine it is compact, improve traditional piping material due at outer wall wave crest with inner wall point
The disadvantage easy to damage of the outer tube wall from caused by, so that the ring stiffness of tubing increases.
Connection rib 13 is respectively arranged to the middle part of four sides of outer wall, is because in the rectangular double-wall corrugated pipe 1 of the plastics
When in use, when operating condition in particular for being embedded in underground, backfill object directly overlays the rectangular double-wall corrugated pipe outer wall 11 of plastics
Around, the power that two sides are subject to up and down of rectangular outer wall is relatively large, and the power that two sides in left and right are subject to is relatively small, and side
The middle part in face is most easily-deformable in stress, it is therefore desirable to which the middle part for connecting the two sides up and down that outer wall is arranged in rib 13 is arranged.
In addition, in order to not have to the top and bottom and left and right face of distinguishing the rectangular double-wall corrugated pipe of plastics in processing and work progress, thus
The middle part in four faces of rectangular 1 outer wall of double-wall corrugated pipe of plastics is all arranged to connection rib 13.In order to increase the rectangular double-walled of plastics
The meter Chong of tubing is minimized while the ring stiffness and ring flexibility of bellows, saves material, only in four sides of outer wall
Middle part setting connection rib 13, other positions are not provided with connection rib 13.
Arc chord angle is set by four apex angles of outer wall wave crest 11, stress concentration is can reduce, increases ring stiffness.
The outer surface that rib 13 protrudes outer wall trough 112 is connected, i.e. connection rib 13 is in the axial direction by outer wall wave crest 111 and outer wall
The series winding of trough 112 is combined together, and increases the ring flexibility of tubing, and when construction pulls and when bending tubing, 111 He of outer wall wave crest
The junction of outer wall trough 112 is not easily broken.
The rectangular double-wall corrugated pipe 1 of plastics passes through extrusion molding mode disposal molding.
The utility model is not limited to the above embodiment, all design, principle, structure and sides based on the utility model
Method, the various improvement made, is within the protection scope of the utility model.
