Description

Filled type throttling spigot-and-socket HDPE winding reinforcing pipes

Technical field

The 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 refers generally to entrance and exit small area excavation in the case of excavating, lay, change and repair various underground utilities Construction technique, over the ground surface drying disturb it is little, therefore with higher social economic effect.Mainly include horizontal directional drilling, push pipe, The technical methods such as micro-tunneling, booster, impact.The technology comes from the 70's of 20th century, and in the 90's incoming China, mesh Before be widely used in the new pipe-line construction and Old pipeline's rehabilitation in the fields such as feedwater, draining, electric power, communication, combustion gas, it is also possible to should For aspects such as historical relic, the protections of ancient building, with the increase of present road traffic flow, loading capacity is substantially improved etc., Geological movement takes place frequently, and the pliability of existing reinforced pipe and overall critical external compressive resistance ability, corrosion-resistant and chemically resistant material corrode Ability is all insufficient to, the rubber ring class joint for being adopted, and in construction, quality of connection, joint is strong, it is ensured that interface material, structure With the uniformity of body itself, aspect can not effectively meet existing needs.

At present reinforced pipe in use, when the hollow tube stress in inner tube, because the hollow inside of hollow tube does not have Elastic buffer structure, so it sometimes appear that the situation of breakage；In addition, the tracing line being arranged on outside hollow tube due to can with it is hollow Pipe comes off so that test pipeline is inaccurate.

Utility model content

The purpose of this utility model seeks to provide a kind of filled type throttling spigot-and-socket HDPE winding reinforcing pipes, and how is solution Make that its tube wall bulk strength is high, be not easily broken, technical problem that is non-leakage and preventing tracing line and hollow tube disengaging.

Filled type throttling spigot-and-socket HDPE winding reinforcing pipes, including inner tube, hollow tube；Respectively welding has circle at the two ends of inner tube The interface of shape and the birdsmouth of circle, wherein interface outer wall is provided with a circle heating, during the inner tube centre position is Hollow cylinder;What hollow tube wound is arranged on outer wall of inner tube, the hollow tube generally cylindrical structural;It includes inner ring and outer ring And three dowels between the two circles;Tracing line is in inner ring；The sky surrounded between inner ring, outer ring, dowel It is interior to be provided with hard metal piece.

Said inner tube and hollow tube fusion are integral.

The heating is made up of wire bending.

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

The wear-resisting line is twine or Oxford line.

There is layer of steel wire net in said inner tube.

The beneficial effects of the utility model are：Inner tube and hollow tube 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 tube is relatively thin, and materials are less, can With performance, can reduces cost；Hard metal piece in the space that inner ring, outer ring, dowel are surrounded, above-mentioned hard metal piece structure Into cushioning effect, so significantly improve the overall critical external compressive resistance ability of whole product and will not separate with hollow tube.Due to hollow Pipe centre position has tracing line, and such tracing line is so as to depart from hollow tube in hollow tube center all the time.

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, 21. inner rings, 22. outer rings, 23. dowels, 3. 24. copper sheets, tracing line.

Specific embodiment

Fig. 1 and Fig. 2 is refer to, the filled type throttling spigot-and-socket HDPE winding reinforcing pipes in figure, including an inner tube 1, 2, hollow tube intensity enhancing part 3 of individual hollow tube.

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 wire 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.In addition, in actual applications, it is also possible to use steel wire and determine twine.

Extruder for shaping is made and adopted to the same entirety of hollow tube 2 using HDPE materials, and it adopts spiral winding Mode is arranged on the outer wall of inner tube 1, and the hollow tube 2 includes the outer ring 22, three of an inner ring 21, dowel 23；Three connections Muscle 23 is between inner ring 21 and outer ring 22；Hard metal is provided with the space surrounded between inner ring 21, outer ring 22, dowel 23 The metal copper sheet 24 of piece such as thin type.In order that inner tube 1 and the intensity of hollow tube 2 are more preferably, inner tube 1 and hollow tube 2 can be fused into whole Body.The overall profile of above-mentioned hollow tube 2 is for cylinder and is laid on the outer wall of inner tube 1.The inner ring inside of hollow tube 2 has tracing line 4。
