Abstract
The invention discloses a spirally reinforced biplanar steel strip polyethylene drain pipe. The drain pipe is made by spirally rolling a strip plate which is spirally wound with the steel strip. The drain pipe is characterized in that: one end of the strip plate is provided with a hollow ridge part, the other end of the strip plate is provided with a vertical rib which has equal height with the ridge part, the ridge part and the rib extend along the length direction of the strip plate, space which is spirally wound by the steel strip is formed at the opposite insides of the ridge part and the rib, the outsides of the ridge part and the rib are provided with a bonding part which is spirally rolled, and the tops of the ridge part, the steel strip and the rib are clad with plastic cement to form a smooth outer wall surface of the pipe. The spirally reinforced biplanar steel strip polyethylene drain pipe has the advantages of high loop stiffness, convenient spigot joint, light weight due to the hollow ridge part, being capable of conveniently setting the density of a wound steel strip, and wide range of suitable pipe diameters from the pipe with smaller pipe diameter to the pipe with larger pipe diameter.
Description
Technical field
The present invention relates to the municipal drainage facility, particularly a kind of steel strip helical reinforced biplane polythene drainpipe.
Background technique
The double-wall corrugated pipe ring stiffness of the pure plastics that use in the urban discharging pipeline is good inadequately, and the waste pipe that spiral rolls is corrosion-resistant, frictional resistance is low, ring stiffness is high and steel is moulded.In recent years, the steel plastic strip water pipe with the steel band reinforced plastics is competitively studied in countries in the world, wherein relatively is typically, and outer surface is the two flat walls steel plastic strip water pipe that the steel plastic strip water pipe that rolls of undulatory spiral and inner and outer surface are hydraulically smooth surface.Wherein, outer surface is that the steel plastic strip water pipe that undulatory spiral rolls has advantage in light weight, that cost is low, ring stiffness is high, but its appearance is a corrugated, connects inconvenience between the pipeline, can not connect the easy seepage in joint by socket joint; Two flat walls steel plastic strip water pipe has the ring stiffness height, be convenient to the advantage that socket joint connects, and is close packed structure but its spiral clamps steel band, caused body weight heavier and consumed great deal of steel, and cost is higher.
Summary of the invention
The objective of the invention is to:, provide a kind of ring stiffness height, steel strip helical reinforced biplane polythene drainpipe that weight is lighter at the deficiencies in the prior art.
Technological scheme of the present invention is:
A kind of steel strip helical reinforced biplane polythene drainpipe, form by banded sheet material helical coil system, spiral is wound with steel band on banded sheet material, it is characterized in that: banded sheet material one end has the spine of a hollow, the other end have hold up, with the contour muscle of spine, spine and muscle all extend along banded sheet material length direction, spine and muscle opposed inside form the space that ribbon spiral twines, the outside of spine and muscle is the adhesive segment that spiral rolls, the top of spine, steel band and muscle is coated with plastic cement, forms the smooth outer wall face of pipeline.
Supplementary technology scheme of the present invention is as follows:
Preferably, can be free to slide relatively between steel band and the banded sheet material.
Preferably, on the adhesive segment in the outside of spine and muscle, projection and the groove that cooperatively interacts arranged.
Preferably, steel band has the top, extends to form sidepiece after the bending downwards from the two ends, top, the bottom of sidepiece bending relatively to the inside again extends to form the bottom, the width of its bottom is greater than the width at top.
Preferably, outstanding in opposite directions cap portion is arranged at the top of the opposite side of spine and muscle.
Preferably, be equipped with rounded corner at spine internal bend place.
Preferably, be provided with rounded corner at banded sheet material and spine, muscle intersection.
Preferably, be provided with rounded corner in cap portion and spine, muscle intersection.
The invention has the beneficial effects as follows: the ring stiffness height, make things convenient for socket joint to connect, in light weight because it has the spine of hollow, and the density of winding steel can conveniently be set, and it is big to adapt to the caliber scope, and the pipeline less from caliber all is fit to the very big pipeline of caliber.In addition, can be free to slide relatively between steel band and the banded sheet material, solve existing steel and moulded behind bellows steel band and the plastic bonding because thermal expansion coefficient is different the shortcoming that the tube wall that causes is torn; Have outstanding in opposite directions cap portion can avoid coating to leak glue in the plastic cement process at the top of the opposite side of spine and muscle and cause the weight of pipeline to increase, cost increases; The rounded corner that is provided with everywhere on banded sheet material can effectively avoid stress to concentrate.

Wherein, reference character: 1 is plastic cement, and 2 is spine, and 3 is steel band, and 4 is muscle, and 5 is cap portion, and 6 is banded sheet material, and 7 is adhesive segment, and 301 is the steel band top, and 302 is the steel band sidepiece, and 303 is the steel band bottom, and 701 is projection, and 702 is groove.
Embodiment
The present invention is further described below in conjunction with drawings and Examples.
Specific embodiments of the invention 2, as shown in Figure 4, a kind of steel strip helical reinforced biplane polythene drainpipe, its structure is similar to Example 1, difference is: on the adhesive segment 7 in the outside of spine 2 and muscle 4 projection 701 and the groove 702 that cooperatively interacts arranged, can be used to strengthen the adhesion strength of adhesive segment.
Specific embodiments of the invention 3, a kind of steel strip helical reinforced biplane polythene drainpipe, its structure is similar to Example 1, mould behind bellows steel band and the plastic bonding because the different pipelines that cause of thermal expansion coefficient are torn for fear of steel, do not bond between steel band 3 and the banded sheet material 6, can be free to slide relatively.
A kind ofly be applied in the foregoing description preferred steel band, as shown in Figure 5, steel band has top 301, extends to form sidepiece 302 after the bending downwards from 301 two ends, top, the bottom of sidepiece 302 bending relatively to the inside again extends to form bottom 303, and the width of its bottom is greater than the width at top.
In the above-described embodiments, leak glue in the plastic cement process and cause the weight of pipeline to increase for fear of coating, cost increases, and at the top of the opposite side of spine 2 and muscle 4 outstanding in opposite directions cap portion 5 is arranged; Stress on the tube wall is concentrated, rounded corner that can each corner is provided with on banded sheet material.
