Abstract
The utility model discloses a dual-rib reinforced double-walled corrugated tube, which comprises an inner wall and an outer wall. Axial section of the outer wall is corrugated, crests of the outer wall are axially independent, troughs of the outer wall are integrated with the inner wall, and a trough position of the outer wall is uniformly provided with at least two reinforcing ribs along the circular direction, the reinforcing ribs are axially arranged inside the troughs of the outer wall. The dual-rib reinforced double-walled corrugated tube is applicable to farmland water irrigation, urban drainage pipes and the like.
Description
Technical field
The utility model relates to a kind of tubing, refers more particularly to the technical field of double-wall corrugated pipe.
Background technique
Traditional double-wall corrugated pipe, as Fig. 3, shown in Figure 4, comprise inwall 1 and outer wall 2, the axial cross section of described outer wall 2 is a corrugated, the crest of outer wall 2 is axially independent, the trough of outer wall 2 and inwall 1 are fused, this type of bellows has the rigidity of hard tube, crushing resistance, the flexibility that has flexible pipe again, therefore, the application of polyethylene double-wall corrugated pipe is very extensive, as be applied to irrigation and water conservancy and irrigate, many aspects such as urban sewage pipe, polyethylene double-wall corrugated pipe in the market, because the crest of its outer wall is axially independently, crest is relative with the trough intensity between the crest just relatively weaker, the surface in trough district also is a polyethylene double-wall corrugated pipe stress rupture concentration zones simultaneously, therefore when constructing in transit or on-site, through the shovel fortune of fork truck or when doing it by hand and carry it on one's shoulder, the trough district of polyethylene double-wall corrugated pipe is easy to damage.
The model utility content
Technical problem to be solved in the utility model is: provide the non-damageable pair of rib in a kind of trough district to strengthen double-wall corrugated pipe.
For addressing the above problem, the technical solution adopted in the utility model is: two ribs strengthen double-wall corrugated pipe, comprise inner and outer wall, the axial cross section of described outer wall is a corrugated, the crest of outer wall is axially independent, the trough and the inwall of outer wall are fused, and the trough place of outer wall evenly is provided with at least two stiffening ribs along hoop, and described stiffening rib is arranged in the trough of outer wall vertically.
The hoop cross section of described stiffening rib is the part annulus.
The beneficial effects of the utility model are: the utility model evenly is provided with at least two stiffening ribs at the trough place of the outer wall of double-wall corrugated pipe along hoop, described stiffening rib is arranged in the trough of outer wall vertically, make and connected into an integral body between crest and the crest, thereby under the prerequisite of the structural advantages that has kept traditional double-wall corrugated pipe, strengthened the intensity in the trough district of double-wall corrugated pipe again greatly.

Among Fig. 3, Fig. 4: 1, inwall, 2, outer wall.
Embodiment
Below in conjunction with accompanying drawing, the two ribs of the utility model are strengthened double-wall corrugated pipe be described in further detail.
As shown in Figure 1 and Figure 2, in the present embodiment, two ribs strengthen double-wall corrugated pipe, comprise inwall 1 and outer wall 2, the axial cross section of described outer wall 2 is a corrugated, and the crest of outer wall 2 is axially independent, the trough of outer wall 2 and inwall 1 are fused, the trough place of outer wall 2 evenly is provided with four stiffening ribs 3 along hoop, and described stiffening rib 3 is arranged in the trough of outer wall 2 vertically, and the hoop cross section of stiffening rib 3 is the part annulus.
The beneficial effects of the utility model are: the utility model evenly arranges at least two reinforcements 3 at the trough place of the outer wall 2 of double-wall corrugated pipe along hoop, described reinforcement 3 is arranged in the trough of outer wall 3 vertically, make between the crest of outer wall 2 and the crest and interconnect, thereby under the prerequisite of the structural advantages that has kept traditional double-wall corrugated pipe, strengthened greatly again the intensity in the trough district of double-wall corrugated pipe.
Claims (2)
1. two ribs strengthen double-wall corrugated pipe, comprise inner and outer wall, the axial cross section of described outer wall is a corrugated, the crest of outer wall is axially independent, the trough and the inwall of outer wall are fused, it is characterized in that: the trough place of outer wall evenly is provided with at least two stiffening ribs along hoop, and described stiffening rib is arranged in the trough of outer wall vertically.
