Description

A kind of 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 was drawn the past from sleeve pipe, to ensure pipeline and railway, the safety of highway.The good toughness of reinforced pipe, cementability are 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 are strong, it is ensured that interface material, structure With the uniformity of body itself, aspect can not effectively meet existing needs.

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 which Wall bulk strength is high, be not easily broken, non-leakage technical problem.

A kind of throttling spigot-and-socket HDPE winding reinforcing pipes, including the reinforcement of hollow inner tube, winding pipe, quality of rubber materials；It is interior Welding has the interface of circle and the birdsmouth of circle respectively at the two ends of pipe, and wherein interface outer wall is provided with a circle heating Or with raised sealing ring, the inner tube centre position is cylinder, inner surface has staggered reinforcement;Winding pipe What is wound is arranged on outer wall of inner tube, and the winding pipe overall profile is square and internal with reinforcement;Above-mentioned reinforcement is generally " V " shapes, the outside and inside of above-mentioned reinforcement have tooth side.

Said inner tube and winding pipe fusion are integral.

The heating is made up of tinsel bending.

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

The wear-resisting line is twine.

The top of the winding pipe has a tracing line.

The beneficial effects of the utility model are：Inner tube and winding pipe are high density polyethylene (HDPE) material using HDPE materials, Which 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 winding pipe is relatively thin, and materials are less, can With performance, can reduces cost, by increasing reinforcement in winding pipe, the both sides of such reinforcement constitute elastic buffer structure, The overall critical external compressive resistance ability of whole product is significantly improved so, the design on tooth side on reinforcement is to improve its volume, increases which whole Body intensity.

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；

1. inner tubes, 11. interfaces, 12. birdsmouths, 121. heatings, 2. 13. wear-resisting lines, winding in figure Pipe, 3. 21. tracing lines, reinforcement, 4. 31. tooth sides, reinforcement.

Specific embodiment

Fig. 1 and Fig. 2 is refer to, a kind of throttling spigot-and-socket HDPE winding reinforcing pipes in figure, including inner tube 1, 2, reinforcement 3 of winding 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, wherein 11 outer wall of interface are provided with a circle heating 121,1 interposition of inner tube Cylinder is set to, 1 inner hollow of inner tube.Above-mentioned heating 121 is made up of tinsel bending.In order to strengthen the strong of inner tube 1 Degree, can set up the such as twine of one layer of wear-resisting line 13 inside inner tube 1, and this layer of 13 one-tenth of wear-resisting line is latticed, so such as wheel tire Equally.1 inner surface of inner tube has the reinforcement 4 being crisscross arranged, and plays the intensity for strengthening inner tube 1 while avoiding the debris in pipe Incised wound 1 inner surface of inner tube.

2 same entirety of winding pipe is made using HDPE materials, and which is arranged on 1 outer wall of inner tube by the way of spiral winding, There is inside the winding pipe 2 reinforcement 3;In order that inner tube 1 and 2 intensity of winding pipe are more preferably, inner tube 1 and winding pipe 2 can be merged It is integral.2 overall profile of above-mentioned winding pipe is square and is laid on 1 outer wall of inner tube.In order to future enters to the winding reinforcing pipe Line trace is positioned, and can fix a tracing line 21 on the top of winding pipe 2, preferably by above-mentioned tracing line 21 directly parcel to twining In pipe 2.

The effect of reinforcement 3 is to keep out external force to prevent foreign object destruction winding pipe 2.The reinforcement 3 it is overall into " V " shape, " V " The design of shape mainly carries out the counteracting of external force using its arc-shaped side.In addition, in order that reinforcement 3 is preferably fitted with winding pipe 2, Prevent the winding pipe 2 when external force extruding winding pipe deforms from departing from reinforcement 3, tool can be made in the outside of reinforcement 3 and inside 31 structure of side with teeth, so increases the bonded area of winding pipe 2 and reinforcement 3.
