Abstract
The utility model discloses a water drainage pipe with high strength and double flatted surfaces, which belongs to water drainage pipe materials. According to the water drainage pipe, a pipe body comprises an inner pressure pipe, wherein the inner pressure pipe is an integrally formed thin-walled pipe; the outer surface of the inner pressure pipe is wound with a strengthening device; the outer side of the strengthening device is spirally wound with a winding structure wall; outer surfaces of the strengthening device and the winding structure wall are coated with a layer of glue respectively; outer sides of the strengthening device and the winding structure wall are wrapped with an outer covering layer respectively; and outer surfaces of outer covering layers form smooth outer walls. The water drainage pipe has the characteristics of high ring stiffness, inner pressure bearing ability, and production efficiency, and low cost, has excellent corrosion resistance, stable property, and reliable working, and is suitable for the using of a urban drainage system.
Description
Technical field
The utility model relates to the drainage pipe technical field, specifically a kind of high strength two flat walls waste pipe.
Background technique
Along with science and technology development, tubing is being brought into play more and more important effect in all trades and professions, and for the drainage system in city, waste pipe is indispensable part.
The material that traditional aqueduct adopts mostly is cast iron or steel greatly, and the employing inner and outer surface layers that also has is cement and inner be the structure of cast iron, these pipelines complexity of often constructing, corrosion-resistant, cost height.Development along with new material, engendered the tubing that replaces metal tube with plastic tube, but the tube wall of plastic tube mostly is single layer structure at present, bear the ability of external pressure, if want tubing to bear bigger pressure, just need to increase the wall thickness of tubing, a series of problem such as will cause like this that materials are many, Heavy Weight, product cost height, manufacturing efficiency are low.
Along with the development of technology, the tube-making process that spiral twines has appearred, though the spiral winding structure wall bears the better performances of external pressure, can't bear interior pressure, if pressure can cause weld cracking in bearing.Need at present a kind of performance that bear external pressure and interior pressure all relatively good and can satisfy the tubing of draining needs.
The model utility content
The purpose of this utility model is to provide a kind of high strength two flat walls waste pipe, this tubing has the ring stiffness height, hold in pressure energy power height, characteristics non-leakage, easy for installation.
The technical scheme in the invention for solving the technical problem is: high strength two flat walls waste pipe, comprise body, it is characterized in that, described body comprises interior pressure pipe, the thin walled tube that pressure pipe is formed in one in described, the outer surface of interior pressure pipe is wound with stiffening device, and the outside spiral of stiffening device is wound with winding structure, and the outer surface of described stiffening device and winding structure scribbles one deck glue respectively; The outside at stiffening device and winding structure evenly is enclosed with one deck surrounding layer, and the outer surface of described surrounding layer forms smooth outer wall.
Described stiffening device is strengthening net or reinforced wire.
Described strengthening net or reinforced wire are made of steel wire or glass fibre.
Described winding structure is banded special-shaped section bar.
Described winding structure is metal or the nonmetal hollow tubular section bar of making.
Compared with prior art, the utlity model has following beneficial effect:
1, by winding structure and surrounding layer are set, improves the ring stiffness of tubing, improved the ability that tubing bears external pressure, under the heavy condition of same caliber same pipe, the bearing capacity of tubing improves greatly, and operational safety is strong, can adapt to bad working environment, Applicable scope is extensive.
2, interior pressure pipe is that extruded type is one-body molded, does not have weld seam, not only can bear interior pressure well, and the manufacturing efficiency height; Be provided with strengthening net or reinforced wire and further improved the ability that tubing is pressed in bearing, reliable operation prevents seepage.
3, be equipped with glue in the outside of stiffening device and winding structure, not only make connection close and firm more between the each several part structure, and when stiffening device and winding structure were metallic material, glue can also play etch-proof effect, prolonged the working life of tubing.
4, the inner and outer wall of tubing is the planomural structure, non-corrugated, wall thickness uniformity, there is not weak link, tube wall performance uniformity, and the two flat walls pipe is convenient to connection and the sealing of joint, easy for installation between tube and tube, pipe and the inspection shaft, installation rate is fast.
Description of drawings

Among the figure: pressure pipe in 1,2 stiffening devices, 3 winding structures, 4 surrounding layers.
Embodiment
Below in conjunction with Figure of description and embodiment the utility model is further described:
High strength two flat walls waste pipe of the present utility model, comprise body, described body comprises interior pressure pipe 1, the thin walled tube that pressure pipe 1 is formed in one in described, the outer surface of interior pressure pipe 1 is wound with stiffening device 2, the outside spiral of stiffening device 2 is wound with winding structure 3, and the outer surface of described stiffening device 2 and winding structure 3 scribbles one deck glue (not shown) respectively; The outside at stiffening device 2 and winding structure 3 evenly is enclosed with one deck surrounding layer 4, and the outer surface of described surrounding layer 4 forms smooth outer wall.
Described stiffening device 2 is strengthening net or reinforced wire, and described strengthening net or reinforced wire are made of steel wire or glass fibre.
The glue that stiffening device 2 and winding structure 3 outer surfaces are coated with is resin dedicated glue, the combination that not only can make winding structure 2 and interior pressure pipe 1, stiffening device 2 and surrounding layer 4 is close and firm more, when stiffening device 2 and winding structure 3 are metallic material, can also play etch-proof effect.
Embodiment one:
As shown in Figure 1, described winding structure 3 is banded special-shaped section bar.
Embodiment two:
As shown in Figure 2, described winding structure 3 is metal or the nonmetal hollow tubular section bar of making.
Tubing ring stiffness height of the present utility model, bearing capacity height, winding structure 3 have improved the ability that tubing bears external pressure, and interior pressure pipe 1 can be born interior pressure.Be provided with stiffening device 2 and further improved pressure energy power in the holding of tubing, can bear the interior pressure that is higher than 0.2MPa, the structure of two flat walls makes tubing not have weak link, and reliable operation is non-leakage, can be widely used in every field such as plumbing.
In addition, the two flat walls pipe is easy for installation, installation rate is fast, and is higher compared with the concrete duct conveying capacity, and low compared with metallic conduit good corrosion resistance, cost, prolong working life greatly.
The above, principles more of the present utility model just explain through diagrams, this specification be not be the utility model to be confined to shown in described concrete structure and the Applicable scope, so every corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
Except the described technical characteristics of specification, all the other technical characteristicss are those skilled in the art's known technology.
