Abstract
The utility model discloses a profiled bar for a winding corrugated pipe with reinforced inner ribs and the winding corrugated pipe with the reinforced inner ribs. The cross section of the profiled bar comprises a bottom portion and more than two hollow reinforced ribs formed on the bottom portion. The profiled bar for the winding corrugated pipe with the reinforced inner ribs is characterized in that a cross rib is arranged in each hollow reinforced rib, and the winding corrugated pipe with the reinforced inner ribs comprises the profiled bars which are wound in a spiral shape and sol layers which are used to combine adjacent profiled bars. Due to the structure of the profiled bar for the winding corrugated pipe with the reinforced inner ribs, the ring stiffness of the winding corrugated pipe with the reinforced inner ribs can be improved.
Description
Technical field
The utility model relates to the profile shapes and the internal-rib that use at internal-rib enhancing winding corrugated pipe and strengthens winding corrugated pipe, particularly is applied in underground winding corrugated pipe.
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 winding corrugated pipe of hollow fin etc.For pvc pipe and straight-through conduit pipe, its general use does not on the ground need to bear too large 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, its thermal expansion coefficient is also different, causes easily inner layer polyethylene and outer layer polyethylene cracking, easily causes quality problems; Winding corrugated pipe with hollow fin occurred in recent years, its profile shapes and sol layer by spiral winding consists of tubular structure, profile shapes has hollow reinforced rib, the defective of its existence is: when the winding corrugated pipe with hollow fin be embedded to underground after, hollow reinforced rib can be subject to radial and axial pressure, owing to be hollow in the hollow reinforced rib, therefore, hollow reinforced rib is out of shape easily under pressure, thereby has reduced the ring stiffness of bellows, easily causes the bellows distortion.
Summary of the invention
For improving the ring stiffness of winding corrugated pipe, the utility model has improved a kind of profile shapes and internal-rib enhancing winding corrugated pipe that strengthens winding corrugated pipe for internal-rib.
The technical solution of the utility model is: be used for the profile shapes that internal-rib strengthens winding corrugated pipe, its cross section comprises a bottom and the plural hollow reinforced rib that is formed on the bottom; In hollow reinforced rib, be provided with cross rib.Internal-rib strengthens winding corrugated pipe and comprises the profile shapes of spiral winding and the sol layer that mutual close profile shapes is combined; The cross section of profile shapes comprises a bottom and the plural hollow reinforced rib that is formed on the bottom; In hollow reinforced rib, be provided with cross rib.
Technique scheme, owing to be provided with cross rib in hollow reinforced rib, when the hollow stiffening rib was subject to radial and axial pressure, cross rib played restriction to the energy of deformation of hollow reinforced rib, effectively reduce the distortion possibility of hollow reinforced rib, thereby improved the ring stiffness of winding corrugated pipe.
As further improvement, hollow reinforced rib is two, be formed at the two end part of bottom, the hollow reinforced rib that is positioned at the two end part, bottom comprises straight support, transition part and circular arc support, transition part is connected between straight support and the circular arc support upper end, and lower end and the bottom of straight support and circular arc support connect as one; Sol layer is formed between the adjacent straight support, and sol layer and mutual bonding straight support form fin.Sol layer is formed between the straight support, has increased the area of welding, thereby has improved the join strength between the heteromorphism; Owing to formed fin, like this, can improve the non-deformability of winding corrugated pipe, further improved the ring stiffness of winding corrugated pipe.
As further improvement, in hollow reinforced rib, be provided with the vertical rib at an angle to each other and crossing with cross rib.This structure can improve the non-deformability of hollow reinforced rib, further improves the ring stiffness of winding corrugated pipe.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
The profile shapes that is used for internal-rib enhancing winding corrugated pipe is banded, and by extruding and moulding, as shown in Figure 1, the cross section of profile shapes comprises a bottom 11 and the plural hollow reinforced rib 12 that is formed on the bottom 11.In the present embodiment, hollow reinforced rib 12 is formed at the two end part of bottom 11, quantity is two, hollow reinforced rib 12 comprises straight support 121, transition part 122 and circular arc support 123, transition part 122 is connected between straight support 121 and circular arc support 123 upper ends, lower end and the bottom of straight support 121 and circular arc support 123 connect as one, and the part of straight support 121, transition part 122, circular arc support 123 and bottom surrounds a cavity 14.In cavity 14, be provided with straight support 121 and be connected the cross rib 13 that is connected with the circular arc support, be used for improving the non-deformability of hollow reinforced rib.
In order further to improve the non-deformability of hollow reinforced rib, the vertical rib at an angle to each other with cross rib can be set in cavity.
To shown in Figure 4, form internal-rib enhancing winding corrugated pipe by the profile shapes 1 of spiral winding with for the sol layer 2 that welds mutually close profile shapes such as Fig. 2.As shown in Figure 1, the cross section of profile shapes comprises a bottom 11 and the plural hollow reinforced rib 12 that is formed on the bottom 11.In the present embodiment, hollow reinforced rib 12 is formed at the two end part of bottom 11, quantity is two, hollow reinforced rib 12 comprises straight support 121, transition part 122 and circular arc support 123, transition part 122 is connected between straight support 121 and circular arc support 123 upper ends, lower end and the bottom of straight support 121 and circular arc support 123 connect as one, the part of straight support 121, transition part 122, circular arc support 123 and bottom surrounds a cavity 14, and sol layer 2 is welded together to form fin with adjacent straight support 121.In cavity 14, be provided with straight support 121 and be connected the cross rib 13 that is connected with the circular arc support.
