Description

A kind of ribbing winding Type B tubing

Technical field

The utility model is related to tubing more particularly to a kind of ribbing to wind Type B tubing.

Background technology

At present in the outdoor buried hollow structure wall drainage pipeline used due to the special real-world environment of material characteristic adaptation, Higher ring stiffness and ring flexibility energy are required, common heavy caliber Type B hollow structure wall wound pipe is (following to be referred to as：B Type winding pipe) there is good corrosion resistance, the features such as inner wall smooth, flow resistance is small, light-weight, anti-settling to be widely used to city Political affairs rain dirt Drainage Projects.

Existing product is due to the limitation of technical matters, and (Type B winds an effective small-bore single-wall corrugated pipe, in tube wall Upper continuous winding, coats, and mainly determines the ring stiffness of tubing by small-bore bellows, since no other share Stress point) be especially heavy caliber (be more than or equal to 800mm) pipeline be unable to reach high ring rigidity 12.5KN requirement and clad compared with Thin, cladding area is larger, and overall structure can all generate disengaging after cracking or including part.

Then, improvement is studied for existing structure and missing, (inside of small-bore pipe) (knot outside is provided in one kind The outside of structure wall) ribbing and allow small-bore pipe and the common stress of external fin, it is tight using continuous coherent winding tubule both shoulders and external fin It is close to weld together, with identical raw material the utility model technology than the similar product ring stiffness of the prior art be higher by 1.6 times plus Rib Type B structure wall wound pipe, to achieve the purpose that with more more practical value.

Utility model content

The utility model provides a kind of ribbing winding Type B tubing to solve the above-mentioned deficiency of the prior art.

The above-mentioned purpose of the utility model is realized by technical solution below：A kind of ribbing winding Type B tubing, including Tubing ontology, the tubing body exterior are equipped with a pair of parallel external fin of wrapped tube ontology, the both sides of the chest to parallel external fin it Between be equipped with slot position, be installed with internally finned tube in slot position, the parallel external fin and internally finned tube are in spiral shape on tubing ontology.

Further, the internally finned tube accounts for internally finned tube overall surface by the surface portion of the parallel external fin cladding in both sides 80%, the tubule for compensating for traditional Type B winding pipe fixes defect of the forced area less than 30%.

Further, the internally finned tube is hollow structure, is internally provided with cross ribs, and key is played for tubing ontology Property improve ring stiffness effect, increase the intensity of pipeline, can preferably adapt to severe geology.

Further, the parallel external fin is the cylindricality facade structures of contour equidistant uniform thickness, and parallel external fin is prefabricated knot Structure, with this body by integral forming of tubing, parallel external fin can not only be used for the mounting groove position of internally finned tube, and be to increase tubing ontology ring stiffness Significant design structure.

Further, the internally finned tube is combined together with parallel external fin by plastics welding, is enhanced pipeline ring stiffness, is subtracted Lack enhancing tubule and the risk for being detached from tubing ontology occurs because contact surface is very little, more can adapt to complicated, severe geology ring Border.

The utility model compared with prior art the advantages of be：The setting of the internally finned tube of the utility model and parallel external fin, Be conducive to enhance pipeline ring stiffness and reduce raw material, internally finned tube is welding as one with parallel external fin, solves heavy caliber and (is more than etc. In 800mm) pipeline is unable to reach the requirement of high ring rigidity (12.5KN), and it is suitable for complicated, severe geological environment, is compensated for Type B modified hollow structural wall tubing cladding small-bore pipe is easily separated from and the insufficient weakness of ring stiffness, in contrast, ribbing Type B structure Wall wound pipe using prefabricated rib structure, and is welded as a whole with internally finned tube and can not be detached from and be twined with traditional hollow wall Type B It is compared around pipe, identical ring stiffness has the characteristics that save 40% raw material.

Specific implementation mode

The utility model is described in further detail with reference to embodiment.

As shown in Figure 1, Figure 2 and Figure 3, a kind of ribbing winds Type B tubing, including tubing ontology 1, outside the tubing ontology 1 Portion is equipped with a pair of parallel external fin 2 of wrapped tube ontology 1, is equipped with slot position 3 between the both sides of the chest to parallel external fin 2, solid in slot position 3 Dingan County is equipped with internally finned tube 4, and the parallel external fin 2 and internally finned tube 4 are in spiral shape on tubing ontology 1.

Further, the internally finned tube 4 accounts for 4 overall surface of internally finned tube by the surface portion that the parallel external fin in both sides 2 coats 80%, the tubule for compensating for traditional Type B winding pipe fixes defect of the forced area less than 30%.

Further, the internally finned tube 4 is hollow structure, is internally provided with cross ribs 5, is played for tubing ontology 1 The key effect for improving ring stiffness, increases the intensity of pipeline, can preferably adapt to severe geology.

Further, the parallel external fin 2 is the cylindricality facade structures of contour equidistant uniform thickness, and parallel external fin is prefabricated knot Structure, with this body by integral forming of tubing, parallel external fin can not only be used for the mounting groove position of internally finned tube, and be to increase tubing ontology ring stiffness Significant design structure.

Further, the internally finned tube 4 is combined together with parallel external fin 2 by plastics welding, enhances pipeline ring stiffness, Reduce enhancing tubule and the risk for being detached from tubing ontology occurs because contact surface is very little, more can adapt to complicated, severe geology Environment.

The operation principle of the utility model：

First, extrusion molding carries the precast construction plate of external fin, and the external fin of precast construction plate is the column of contour equidistant uniform thickness Shape facade structures are evenly distributed in precast construction plate surface, the internally finned tube of enhancing are buckled between two external fins and to two The contact position of shoulder carries out welding and makes one, and the cross reinforcement rib structure and precast construction plate inside internally finned tube are put down Row external fin improves the ring stiffness of tubing ontology and compares traditional Type B structure wall wound pipe with using same with having big radian Material doubles the characteristics of ring stiffness, and internally finned tube goes along with sb. to guard him in external fin large area and solves traditional product because of tubule and tube wall Between the small defect being easily separated from of contact surface, the utility model effectively raises the ring stiffness of tubing, original is greatly saved The usage amount of material can use in the high buried pipeline project of more complicated landform and construction requirement.

The above specific embodiments are only exemplary, is to preferably make skilled artisans appreciate that originally Patent, be not to be construed as include to this patent range limitation；As long as appointing according to made by spirit disclosed in this patent How with change or modification, the range that this patent includes is each fallen within.
