Abstract

The utility model relates to a multiple walls spiral twined pipes, belonging to the architectural engineering tube, mainly used in the pumping main tube of the municipal construction project, which is characterized in that the tube consists of two layers of tube walls surfaces and internally consisting of a square-tube shape abnormity belt material and a built-up bonding layer which are screwedly twisted and adhered with one another, and a hollow interlayer which is arranged and between the two layers of tube walls surfaces and internally and screwedly communicated with the two tube walls, and provided with horizontal and upright reinforcement plates which a re connected as a whole. The utility model has the advantages of simple structure, easy processing and making, light weight, convenient fixing and transport, low cost and engineering cost, high strength and long service time, in addition, preventing the seepage, saving the raw material and increasing the environmental protection capability.

Description

Multiple wall winding tube

A kind of multiple wall winding tube belongs to construction engineering tubing technical field, is mainly used in urban engineering project draining blowdown main pipe.

In the prior art, trunk sewer pipeline on the urban engineering project generally all adopts cement pipe.This pipe need consume a large amount of reinforced concrete, thick heaviness, and installation and transportation are all inconvenient, the difficult maintenance of easy to leak, working life is short, in case run-down, both befouling environment, obstruction again.Replace cement pipe with double-wall corrugated pipe, though can overcome the defective of cement pipe, its manufacturing mechanism and technology are all complicated, thereby cost an arm and a leg, and are difficult to apply.Design successfully at the beginning of the application two designers and applied for that with the name of Han Ruihong application number is No. 01216004.0 " heavy caliber eat dishes without rice or wine band entwining tube ", though can solve above-mentioned technical barrier, but, use and find in the practice that its intensity remains further to be strengthened because it is a large-diameter pipe.

It is a kind of simple in structure that the purpose of this utility model is to provide, easy processing and fabricating, and the rice heavy and light is saved raw material, and cost is low, and installation and transportation are convenient, and the engineering construction cost is low, can prevent seepage, and the higher multiple wall winding tube of intensity.

According to the physicochemical characteristic of plastics and urban construction requirement to the drain header road, at prior art No. 01216004.0 existing questions in first to file particularly, basic design of the present utility model is: substantial improvement in addition on the basis of No. 01216004.0 patent application, the i.e. hollow interlayer that communicates at spiral, that is from " mouth " word that connects with adhesive layer one by one of being seen along axis vertical profile section, add 1～5 road and " mouth " word four limits or the reinforcement gusset that is connected as a single entity of both sides wherein, they both can 1～3 road horizontal parallel be arranged in " mouth " word, also can vertically be arranged in parallel in 1～3 road, one vertical or two levels, the one vertical or two vertical one horizontal cross arrangements of an all right level, thereby make entwining tube form multiple wall, to strengthen the intensity of integral tube.

Multiple wall winding tube described in the utility model constitutes by twining outer wall 5 and the inner layer tube wall 4 that is bonded mutually and be clipped in the hollow interlayer 3 that spiral communicates between them with square tube type heterotypic strip 1 with its adhesive layer 2 spirals side by side, it is characterized in that also being provided with 1～5 road and strengthen

gusset

6 and 7 in above-mentioned hollow interlayer 3.

Above-mentioned

reinforcement gusset

6 and 7, can be the reinforcement gusset 6 that only has 1～3 road vertical, only have 1～3 road horizontal stiffener plate 7, vertically to strengthen gusset 6 and 1～2 road horizontal stiffener plate 7 intersects, a horizontal stiffener plate 7 and 1～2 road vertically strengthen gusset 6 intersect in any structural type.

The utility model has the advantages that: simple in structure, manufacturing easily, the rice heavy and light is saved raw material, be convenient to install and transportation, cost and operating expenses all can reduce significantly, and intensity is higher, and be sturdy and durable, compare with traditional cement pipe, can prolong 5～10 times working life, and can prevent seepage, fundamentally solve " double-wall corrugated pipe " and " solid band entwining tube " existing separately technical barrier.

Accompanying drawing 1 is got a bit of along axis vertical profile cross-sectional configuration schematic representation of product for one of the utility model most preferred embodiment;

Accompanying drawing 2 is local section structural representation in the accompanying drawing 1 that has amplified.

In conjunction with the accompanying drawings and most preferred embodiment, further describe structure characteristic of the present utility model as follows: with its cross section is that 19 * 19 (mm) wall thickness is the high score material square tube heterotypic strip 1 of 2.5mm, be that spiral twines on the plug of 300mm at external diameter, forming external diameter is the tubulose of 338mm, between every adjacent side cross tube shape heterotypic strip 1 sidewall, be outer wall 5 and the inner layer tube wall 4 of 2.5mm and be clipped between this two wall spiral connection mutually and wherein have wall thickness to be 2mm and link to each other respectively on four limits up and down with it, be the vertical reinforcement gusset 6 of " ten " word intersection and the sphere of movements for the elephants shape hollow interlayer 3 of horizontal stiffener 7 for the adhesive layer 2 of 6mm is bonded into regular wall thickness mutually again with wide.

Change as present embodiment:

1, all according to actual needs and suitably changes such as the external dimension of the shape of irregular belt material and external dimension and whole tubing;

2, can only establish 1～3 road horizontal stiffener plate 7 or vertically strengthen stiffened panel 6 in the hollow interlayer, also can a level two vertically or two levels one vertically intersect, but square crossing can intersect again at an angle.

Claims
