Abstract

The utility model discloses a special-outer wall buried combination pipeline, belongs to a pipeline and mainly solves the technical problems that the common round pipe is deformed under the action of external force, is inconvenient to transport and the like in the prior art. The main technical scheme is that two or more than two pieces of pipe tiles form a pipe section; the upper part of the pipeline has an arched structure or has a herringbone with a fillet, so that when the pipeline bears an external load, the external force is dispersed and the inner diameter of the pipeline is not deformed; the pipe tiles are fixedly connected with reinforcing ribs, and are made of metallic or nonmetallic materials; and the pipe tiles and pipe sections can be connected through hot melting, cold melting, welding, buckling, screws, riveting, holt melt belts or thermal shrinkage belts. The special-outer wall buried combination pipeline solves the technical problem that a pipeline with a true round outer wall has large deformation under the action of the external load to influence the water flow quantity, solves the problems of high transport cost, high manufacturing cost and the like of an integrally round pipeline, and is widely applied to community sewage pipelines and municipal buried drainage pipelines.

Description

The outer wall abnormity buries the ground combination pipe

Technical field

The utility model relates to a kind of pipeline, particularly a kind of ground combination pipe that buries.

Background technique

At present, common buried pipeline mostly is to adopt whole pipe, and this unitary circular pipeline transport and manufacture cost are all than higher; And the pipe thickness of this common pipe all is identical, because of the power that is squeezed is prone to produce distortion with burying, so exist because of amount of deformation under the big external loads effect is big, influences the technical problem of the water yield.Present in the world all this numerical value indexs of extensive use ring stiffness are represented the critical external compressive resistance load capacity of plastic underground waste pipe.If the ring stiffness of tubing is too little, excessive deformation possibly take place or the lateral deflection unstable failure occur in tubing.Otherwise, if ring stiffness is selected De Taigao, must adopt excessive cross sectional moment of inertia, will cause too much with material, cost is too high.For how ensureing ring stiffness, can save cost again, this is the difficult problem of exist actually.Although also the someone has proposed the notion of special pipe; Like the Chen Zhiwen of No. 40, the positive main road of the husky head in Chang'an, Dongguan City, Guangdong Province town in " special-shaped pipeline " (application number: CN200520059095.0 of application on June 3rd, 2005 utility model patent; Notification number: CN2821341); It comprises inner cavity of pipe and pipeline outer wall, and pipeline outer wall is that at least one straight line is connected with a curve.Hypotenuse like right-angled triangle changes curve into, and pipeline outer wall is close on the wall, and a straight line or many straight lines change curve in the polygonal of aforementioned tube pipeline outer wall; Inner cavity of pipe is polygonal, circular arc; Inner cavity of pipe is divided into a plurality of cavitys; It mainly is that solution is convenient to install more firm; Angle more attractive in appearance considers a problem with making profile, and it is to be used for body of wall etc. to locate not have and use under the extruding force situation, so it is not yet considered and design from the angle that improves ring stiffness; Therefore; It is suitable on the buried pipeline, and it also is a kind of integrated piping, also is unfavorable for large batch of transportation.

Summary of the invention

The purpose of the utility model provide a kind of produce outer wall abnormity lower with user cost and that have certain crush resistance bury combination pipe.

The utility model solves the technological scheme that its technical problem adopted: it is columniform pipeline section that outer tube wall watt combines inner chamber by the pipe more than two or two, and said pipeline compression face is arch or the herringbone structure that has fillet.The section configuration of said pipeline outer wall is that part in compression is that arch ellipse or man type, the counterpart that has fillet are rounded square or fillet polygonal.Said pipe watt is provided with or does not establish the reinforcement rib, strengthens rib and connects firmly on pipe watt disposable machine shaping or secondary operations moulding.Adopt that hot melt connection, cold cut connection, welding, snapping, screw are fastening being connected between said pipe watt and the pipe watt, between pipeline section and the pipeline section, the mode of riveted joint or hot melt band, shrink belt connects.Combined type tubing is processed by metal or nonmetallic material.

The beneficial effect of the utility model is: it solved outer wall be positive circular pipe externally under the load action amount of deformation big, influenced the technical problem of the water yield, and solved problems such as unitary circular pipeline transport cost height, manufacture cost height.Be widely used in sub-district blowdown drainage pipeline and municipal buried drain pipe road.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is explained further details.

Embodiment 1; The utility model is that watt to combine inner chamber by the pipe more than two or two be columniform pipeline section, and the section configuration of pipeline outer wall is that part in compression is that arch man type, counterpart oval or that have a fillet are that rounded square, fillet polygonal or other are irregularly shaped; And pipe watt with manage watt between, can adopt that hot melt connection, cold cut connection, welding, snapping, screw are fastening being connected between pipeline section and the pipeline section, riveted joint or modes such as hot melt band, shrink belt connect; Its tubing can adopt metal or nonmetallic material to process, comprising macromolecular material and alloy thereof.Consult Fig. 1 to Fig. 4.

Embodiment 2, and said pipe watt is provided with the reinforcement rib, strengthen rib to increase pipeline strength through on pipe watt, connecting firmly, and it both can disposable machine shaping or secondary operations moulding.Consult Fig. 1 to Fig. 4, all the other are with embodiment 1.
