Description
[technical field]
The utility model relates to a kind of polyethylene double-wall corrugated pipe, particularly one many stiffening ribs polyethylene double-wall corrugated pipe.
[background technique]
Now generally adopted plastic pipe to be applied under ground piping, double wall corrugated high-density polyethylene pipes is also classified as first-selected tubing.In structure due to traditional high density polyethylene (HDPE) bellows, ripple tube layer outer surface and basal body pipe independent of one another, this structure is unfavorable for the adjustment of ripple intraductal pressure, also therefore has influence on double wall corrugated high-density polyethylene pipes global stability, causes its working life too short.
[model utility content]
The utility model provides a kind of many stiffening ribs polyethylene double-wall corrugated pipe, to improve resistance to compression, the shock resistance of bellows.
In order to solve above-mentioned Problems existing, the utility model have employed following technical proposal:
Many stiffening ribs polyethylene double-wall corrugated pipe, comprise the polyethylene corrugated tube layer that smooth polyvinyl piping materials matrix and helical disk are entangled in tubing outer surface of matrix, tubing outer surface of matrix is provided with the stiffening rib of four or six axis, and stiffening rib runs through the ripple struction of ripple tube layer; Stiffening rib inner hollow also communicates with the ripple struction inside of ripple tube layer.
Further modified embodiment: in stiffening rib, the cross section of skeleton is hollow Crown structure, is enclosed with polyethylene surrounding layer outside the crown skeleton of hollow.
Article four, the stiffening rib of axis is along tubing matrix excircle 90 degree distribution.Or six the stiffening rib of axis is along tubing matrix excircle or 60 degree of distributions.
Many stiffening ribs polyethylene double-wall corrugated pipe described above, is characterized in that: described polyethylene corrugated tube layer, polyethylene surrounding layer are all melting adhered with tubing matrix pipe shaft.
Many stiffening ribs polyethylene double-wall corrugated pipe described above, is characterized in that: the crown skeleton thickness of described hollow is the half of polytene corrugated tube layer thickness.
The beneficial effects of the utility model are:
1, the utility model belongs to Green Product, pollution-free, corrosion-resistant, and wear resistance is good, and more durable than steel, cement pipe, cheaply construct, engineering comprehensive cost is low, is convenient to transport and construction; Bellows, soil and pipeline itself bear the pressure of Soil Surrounding jointly, and form pipeclay acting in conjunction, anti-settling performance is good, and based process requires low, are applicable to weak soil drift sand ground.
2, tubing outer surface of matrix is provided with the stiffening rib of four axis, and stiffening rib inner hollow also communicates with the ripple struction inside of ripple tube layer; In stiffening rib, the cross section of skeleton is hollow Crown structure, be enclosed with polyethylene surrounding layer outside the crown skeleton of hollow, and the crown skeleton thickness of hollow is the half of polytene corrugated tube layer thickness, structure is simple, greatly can improve the stability of bellows, strengthen bellows resistance to compression, shock resistance.

[embodiment]
As shown in Figure 1, many stiffening ribs polyethylene double-wall corrugated pipe, comprise the polyethylene corrugated tube layer 2 that smooth polyvinyl piping materials matrix 1 and helical disk are entangled in tubing outer surface of matrix, tubing matrix 1 outer surface is provided with the stiffening rib 3 of four axis, and stiffening rib 3 runs through the ripple struction of ripple tube layer 2; Stiffening rib 3 inner hollow also communicates with the ripple struction inside of ripple tube layer 2.
Embodiment one as shown in Figure 2 and Figure 3, stiffening rib 3 cross section is hollow semicircular structure, and hollow semicircular stiffening rib 3, polyethylene corrugated tube layer 2 are all melting adhered with tubing matrix 1 pipe shaft; Article four, the stiffening rib of axis is along tubing matrix excircle 90 degree distribution.
Embodiment two as shown in Figure 4, Figure 5, in stiffening rib 3, the cross section of skeleton 31 is hollow Crown structure, is enclosed with polyethylene surrounding layer 32 outside the crown skeleton 31 of hollow; Polyethylene corrugated tube layer 2, polyethylene surrounding layer 32 are all melting adhered with tubing matrix 1 pipe shaft, and hollow crown skeleton 31 thickness is the half of polyethylene corrugated tube layer 2 thickness.Article four, the stiffening rib 3 of axis is along tubing matrix 1 excircle 90 degree distribution.
