Abstract
The utility model relates to an industrial tubular product, especially a vertical muscle double -walled bellows that adds, its characterized in that: this vertical muscle double -walled bellows that adds comprises outer and inlayer, be in the same place through the hot melt butt fusion between skin and the inlayer, the inlayer is vertical ripple and adds muscle structural layer, the outer hoop ripple struction layer that is. The utility model discloses vertical muscle double -walled bellows that adds has good vertical anti bending strength, encircles rigidity height (being that hoop compressive capacity is strong) simultaneously, wears cable convenient (the inlayer has good guide effect, and the friction with cable or cable simultaneously becomes some frictions by the face friction, and area of contact reduces, greatly reduced frictional force), and the application property is good etc. Good, be an ideal power cable with or for communications cable protective case.
Description
Technical field
The utility model relates to a kind of Country Tubular Goods, particularly relates to a kind of longitudinal reinforcement double-wall corrugated pipe.
Background technology
The tubing in the fields such as current power cable, telecommunication enclosures, draining blowdown is generally polypropylene single-wall corrugated pipe and HDPE double-wall corrugated pipe, wherein there is following shortcoming in polypropylene single-wall corrugated pipe: 1, because being single layer structure, holding capacity there is fault of construction, ring stiffness is relatively low, particularly the longitudinal strength of tubing is too low, too easily bend, in construction, easy appearance bends up and down, causes cable to pass through; 2, because its outer wall is hoop ripple struction, there will be tubing when non-excavating construction, in outer wall trough, can the foreign matters such as stone be snapped in, cause the frictional force of outer pipe wall and soil large, improve resistance when tubing is drawn, can easily break, non-excavating construction requirement cannot be met; 3, because it only has one deck wall, therefore there is a big difference compared with the composite strengthening tubing of sandwich construction for shock resistance destructiveness.There is following shortcoming in HDPE double-wall corrugated pipe: 1, HDPE material is softer, and ring stiffness is low; 2, vicat softening point temperature is lower, can not meet electric power applications; 3, because its outer wall is hoop ripple struction, there will be tubing when non-excavating construction, in outer wall trough, can the foreign matters such as stone be snapped in, cause the frictional force of outer pipe wall and soil large, improve resistance when tubing is drawn, can easily break, non-excavating construction requirement cannot be met; 4, because it is hoop ripple struction, the longitudinal strength of tubing is very low, easily bends, and in construction, easy appearance bends up and down, causes cable to pass through.
Summary of the invention
The utility model solves the technical scheme that its technical problem adopts, and be to provide a kind of longitudinal strength high, ring stiffness is high, and stretching resistance is strong, and meets longitudinal reinforcement double-wall corrugated pipe of non-excavating construction requirement.
The utility model is achieved in that longitudinal reinforcement double-wall corrugated pipe, comprise longitudinal ripple reinforced structure layer, described longitudinal ripple reinforced structure layer is internal layer, be placed in hoop ripple struction layer in skin, the corresponding contact place between described longitudinal ripple reinforced structure layer and hoop ripple struction layer by hot-melt welds together.The lateral cross section of described longitudinal ripple reinforced structure layer is corrugated ring structure.Described longitudinal ripple reinforced structure layer and hoop ripple struction layer are modified polypropene structure sheaf or modified poly ethylene structure sheaf.
Described longitudinal ripple reinforced structure layer, wall thickness is about 1-5mm, and crest height is 3 ~ 10mm about.
Described hoop ripple struction layer, wall thickness is about 1-8mm, and crest height is about 10 ~ 50mm.
The production method of above-mentioned longitudinal reinforcement double-wall corrugated pipe, the steps include:
Step 1, extrude outer field hoop ripple struction layer with an extruder;
Step 2, extrude internal layer with another extruder, under the effect of high temperature, by there being the shaping water jacket of longitudinal ripple shape, after vacuum suction and cooling and shaping, form internal layer is longitudinal ripple reinforced structure, outer longitudinal reinforcement double-wall corrugated pipe for hoop ripple struction.
Longitudinal reinforcement double-wall corrugated pipe described in the utility model has the following advantages: 1, because internal layer is longitudinal ripple reinforced structure layer, greatly improve the buckling strength of tubing, make tubing not easily occur bending situation; 2, because internal layer is longitudinal ripple reinforced structure layer, when wearing cable or cable, cable or cable and pipe material inner wall form point cantact, greatly reduce the contact area of cable or cable and pipe material inner wall, longitudinal ripple reinforced structure layer has good guide effect simultaneously, greatly reduces the frictional force of cable or cable and pipe material inner wall, therefore, be conducive to passing through of cable or cable, greatly improve construction convenience; 3, because outer pipe wall is hoop ripple struction layer, greatly improve the compression strength of tubing, ring stiffness can reach 50kN/m
2above; 4, special material modified because using, the good heat resistance of tubing, is highly suitable for cable protection; 5, because being double-layer structure, the destructive single wall tubing more general of shock resistance of tubing is good, when any one deck is damaged, does not affect the normal use of tubing.

Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in detail.
As shown in accompanying drawing 1-4, it is the longitudinal reinforcement double-wall corrugated pipe of one described in the utility model, comprise longitudinal ripple reinforced structure layer 1, described longitudinal ripple reinforced structure layer 1 is internal layer, be placed in hoop ripple struction layer 2 in skin, the corresponding contact place between described longitudinal ripple reinforced structure layer 1 and hoop ripple struction layer 2 by hot-melt welds together.The lateral cross section of described longitudinal ripple reinforced structure layer 1 is corrugated ring structure, and hoop ripple struction layer 2 is single-wall corrugated pipe structure, is prior art.
as shown in Figure 5,described longitudinal ripple reinforced structure layer 1, wall thickness e is about 1-5mm, and crest height h is 3 ~ 10mm about, adopts through the excellent polypropylene material of the lubrification of modification or modified polyethylene material, can reduce cable or the frictional force of cable when passing through, and improves efficiency of construction.
as shown in Figure 6,described hoop ripple struction layer 2; wall thickness e is about 1-8mm; crest height h is about 10 ~ 50mm; adopt modified polypropylene material or the modified polyethylene material of good strength; its structure is hoop ripple struction; tubing compression strength can be improved, i.e. ring stiffness, internal layer be played a good protection simultaneously.
