Description

Throttling spigot-and-socket HDPE winding reinforcing pipes

Technical field

This utility model is related to tubing technology, more particularly to a kind of HDPE reinforced pipes.

Background technology

Reinforced pipe is exactly a kind of cement sleeve pipe or steel bushing can be installed typically under roadbed with railroad crossing, the pipeline of highway Pipe, reinforced pipe drew the past from sleeve pipe, to ensure pipeline and railway, the safety of highway.The good toughness of reinforced pipe, cementability is non- Chang Hao, it is ensured that the smooth laying of pipeline engineering.

Belong to the one side of trenchless technology, trenchless technology is referred to by means such as guiding, directional drillings, in earth's surface pole Fraction excavate in the case of, lay, change and repair the construction technique of various underground utilities, over the ground surface drying disturb it is little, therefore With higher social economic effect.Mainly include the technical sides such as horizontal directional drilling, push pipe, micro-tunneling, booster, impact Method.The technology comes from the 70's of 20th century, and in the 90's incoming China, feedwater, draining, electricity is widely used at present The new pipe-line construction in the fields such as power, communication, combustion gas and Old pipeline's rehabilitation, it is also possible to be applied to the side such as protection of historical relic, ancient building Face, with the increase of present road traffic flow, loading capacity is substantially improved etc., and geological movement takes place frequently, existing enhancing The ability that the pliability of pipe and overall critical external compressive resistance ability, corrosion-resistant and chemically resistant material corrode all is insufficient to, the rubber for being adopted Cushion rubber class joint, in construction, quality of connection, joint is strong, it is ensured that interface material, the structure and body uniformity of itself, aspect Existing needs can not effectively be met.

Utility model content

The purpose of this utility model seeks to provide a kind of throttling spigot-and-socket HDPE winding reinforcing pipes, and solution manages how it Wall bulk strength is high, be not easily broken, non-leakage technical problem.

Throttling spigot-and-socket HDPE winding reinforcing pipes, including inner tube, hollow pipe, resilient reinforcement；Melt respectively at the two ends of inner tube The interface of circle and the birdsmouth of circle are connected to, wherein interface outer wall is provided with the sealing of a circle heating or protrusion Circle, the inner tube centre position is cylinder, and the internal tube is hollow;What hollow pipe wound is arranged on outer wall of inner tube, the hollow pipe Inside has above-mentioned resilient reinforcement;Above-mentioned resilient reinforcement both sides are the tensile members of symmetrical " J " shape, centre propping up for flute profile Support member.

Said inner tube and hollow pipe fusion are integral.

The heating is made up of tinsel bending.

There is one layer of wear-resisting line in said inner tube.

The wear-resisting line is twine.

The hollow pipe is " D " shape.

The support member bottom has a breach.

The both sides of the hollow pipe are respectively provided with a tracing line.

The resilient reinforcement inside has particulate matter.

The beneficial effects of the utility model are：Inner tube and hollow pipe are high density polyethylene (HDPE) material using HDPE materials, It has the ability that extremely strong corrosion-resistant and chemically resistant material corrodes, in conveying corrosive fluids or in the extremely strong soil of corrosivity Without any preservative treatment when laying, performance is significantly better than other tubing.The tube wall of the hollow pipe is relatively thin, and materials are less, can With performance, can reduces cost, by increasing reinforcement in hollow pipe, the both sides of such reinforcement constitute elastic buffer structure, So significantly improve the overall critical external compressive resistance ability of whole product.Particulate matter is added by resilient reinforcement inside, is so improved whole The intensity of individual product.

Description of the drawings

Fig. 1 is the schematic diagram that two winding pipe are combined together；

Fig. 2 is shown in the schematic diagram that interface is provided with heating；

It is 1. inner tubes in figure, 11. interfaces, 12. birdsmouths, 121. heatings, 13. wear-resisting lines, 2. hollow Pipe, 3. 21. tracing lines, reinforcement, 31. tensile members, 32. support members, 4. 321. breach, particulate matter.

Specific embodiment

Fig. 1 and Fig. 2 is refer to, the throttling spigot-and-socket HDPE winding reinforcing pipes in figure, including an inner tube 1, is hollow 2, reinforcement 3 of pipe.

Inner tube 1 is overall to be made using HDPE materials, its two ends respectively welding have circular interface 11 and with above-mentioned grafting The corresponding circular birdsmouths 12 of mouth 11, the wherein outer wall of interface 11 is provided with a circle heating 121, the interposition of inner tube 1 Cylinder is set to, the inner hollow of inner tube 1.Above-mentioned heating 121 is made up of tinsel bending.In order to strengthen the strong of inner tube 1 Degree, can set up one layer of wear-resisting line 13 such as twine inside inner tube 1, and this layer of wear-resisting 13 one-tenth of line is latticed, so such as wheel tire Equally.

The same entirety of hollow pipe 2 is made using HDPE materials, and it is arranged on the outer wall of inner tube 1 by the way of spiral winding, The inside of hollow pipe 2 has reinforcement 3;In order that inner tube 1 and the intensity of hollow pipe 2 are more preferably, inner tube 1 and hollow pipe 2 can be merged It is integral.The longitudinal section of above-mentioned hollow pipe 2 is laid on the outer wall of inner tube 1 into semicircle i.e. " D " shape.In order to future strengthens the winding Pipe is tracked positioning, can fix a tracing line 21 in the both sides of hollow pipe 2, preferably directly wraps above-mentioned tracing line 21 Wrap up in hollow pipe 2.

The effect of reinforcement 3 is to keep out external force to prevent foreign object from destroying the soft materials such as hollow pipe 2, preferred rubber.The enhancing The both sides of part 3 are the tensile members 31 of symmetrical " J " shape, and the design of " J " shape mainly carries out the counteracting of external force using its arc-shaped side.Increase The centre of strong part 3 is the support member 32 of flute profile, and the bottom of support member 32 is had a breach 321, designed into one by such Step improves its elastic acting force.

This utility model is existing to make it be wrapped in inner tube 1 internal reinforcement 3 by extrusion die extrusion, is then using Another extrusion die makes hollow pipe 2 on its winding reinforcement 3, finally to pour into particulate matter 4 such as grains of sand thing toward inside reinforcement 3 Matter.
