Abstract
The utility model discloses an enhancement-type helical bellow with an inner rib tubular product. The enhancement-type helical bellow with the inner rib tubular product comprises an inner-layer tube wall and an outer-layer tube wall. A spiral hollow-shaped convex rib is formed on the outer-layer tube wall. The enhancement-type helical bellow with the inner rib tube is characterized in that a tubular product is arranged inside the hollow-shaped convex rib. The transversal surface of the tubular product comprises a frame body, a transverse rib and a longitudinal rib, wherein the transverse rib and the longitudinal rib are mutually angled and placed inside the frame body. The helical bellow structure can bear big radial pressure, and the helical bellow has high ring stiffness.
Description
Technical field
The utility model relates to helical bellows.
Background technique
Traditional sewage treatment drainage pipe adopts concrete duct, and this pipeline needs all at the scene construction, the construction inconvenience very of getting up, and construction cost is high, and can not be repeated to utilize, and also be subject to certain restrictions working life.
Based on above-mentioned many defectives, developed into afterwards in order to adopt steel pipe as blow-off line, but had the defective that cost is high, working life is short.
In recent years, along with the wilderness demand to municipal pipeline, and for some technological deficiencies before overcoming, many plastic pipes have appearred, such as pvc pipe, straight-through conduit pipe, reinforced steel-band helical bellows, have the helical bellows of hollow fin etc.For pvc pipe and straight-through conduit pipe, its general use does not on the ground need to bear great radial pressure, and is therefore, less demanding to the ring stiffness of tubing.For the reinforced steel-band bellows, because steel band is different with poly material, therefore, easily cause following problem: (1) is in shaped-steel strip enhancement mode helical bellows forming process, steel band and poly combination are difficult, (2) steel band is different with poly coefficient of thermal expansion and contraction, then along with the checker of temperature, because of the amount of deformation difference, easily cause inner layer polyethylene and the polyethylene of going out to split in steel band punishment, steel band is separated with outer layer polyethylene, thereby affect the intensity of reinforced steel-band bellows; In addition, at present use the steel band cross section in helical bellows to be arc, and extend extension part at the two ends of arc, right extension part contacts with inner layer polyethylene, allow arc-shaped steel belt contact with outer layer polyethylene, most of ring stiffness of steel-belt-pipe enhancement mode helical bellows is provided by the non-deformability of arc-shaped steel belt, when the reinforced steel-band helical bellows be embedded to underground after, can be subject to radial pressure and lateral pressure from soil layer in the position of steel band, and arc-shaped steel belt exists certain span, and along with the span increase of arc-shaped steel belt, then its anti-pressure ability also reduces, easily cause the distortion of helical bellows, namely ring stiffness does not reach the requirement of use.
Summary of the invention
The purpose of this utility model provides a kind of band internal-rib tubing enhancement mode helical bellows, and helical corrugation tubular construction of the present utility model can bear larger radial pressure, and the ring stiffness of helical bellows is high.
For achieving the above object, band internal-rib tubing enhancement mode helical bellows comprises inner layer tube wall and outer wall, is formed with the hollow shape fin of spiral at outer wall; Be provided with tubing in the hollow shape fin, the cross section of tubing comprises framework and is positioned at cross rib at an angle to each other and the vertical rib of framework.
As further improvement, cross rib and vertical rib are mutually 90 degree.
As further improvement, framework comprises the contacting part that contacts with inner layer tube wall and the curved portions of extending and contacting with hollow shape internal-rib inwall from the contacting part two ends.
The beneficial effects of the utility model are: owing to being provided with cross rib and the vertical rib of alternating layers angle, when having soil layer to be applied on the tubing, under the interaction of cross rib and vertical rib, can effectively limit the tubing distortion, thereby improved the non-deformability of the utility model band internal-rib tubing enhancement mode helical bellows, improved ring stiffness.In addition, owing to being provided with the hollow shape fin, be landfilled soil layer between the adjacent hollow shape fin, like this, can have prevented that then the helical bellows that is embedded in from moving axially, made helical bellows be not easy to be subjected to displacement.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
As shown in Figure 1 to Figure 3, band internal-rib tubing enhancement mode helical bellows comprises inner layer tube wall 1, outer wall 2.Be formed with the hollow shape fin 3 of spiral at outer wall 2, be provided with tubing 4 in the hollow shape fin 3.
Described tubing 4 comprises the contacting part 41 that contacts with inner layer tube wall 1, the curved portions 42, cross rib 43 and the vertical rib 44 that stretch out and contact with hollow shape fin 3 inwalls from contacting part 41 two ends.Contacting part 41 and curved portions 42 form framework, are cavity body in the framework, and cross rib 43 and vertical rib 44 are positioned at cavity body, cross rib 43 is connected with framework with the end of being connected rib 44, is arc transition in the joint, prevents that stress is concentrated, in the present embodiment, the angle between cross rib 43 and the vertical rib 44 is 90 degree.
In the present embodiment, band internal-rib tubing enhancement mode helical bellows be embedded to underground after, the helical bellows major embodiment be to bear from the soil layer radial pressure, for hollow shape fin 3, soil layer can be embedded between the adjacent hollow shape fin and the hollow shape fin on, bear radial pressure and axial pressure.In the present embodiment, owing to having cross rib 43 and vertical rib 44 in the framework, when having radial compression applied to the tubing, cross rib 43 and vertical rib 44 can effectively limit the tubing distortion, thereby have improved the non-deformability of enhancement mode helical bellows, to improve ring stiffness.In addition, owing to being provided with hollow shape fin 3, be landfilled soil layer between the adjacent hollow shape fin, like this, can have prevented that then the helical bellows that is embedded in from moving axially, made helical bellows be not easy to be subjected to displacement.
