Abstract

The utility model discloses a compound pipe of two rubber circle socket joint formula steel pipe concrete. The compound pipe of this kind is including steel pipe, bellmouth steel loop, socket steel loop, recess, inside lining concrete. Main characterized in that: at the one end welding bellmouth steel loop of steel pipe, other end welding socket steel loop, the rubber circle is placed to socket end outer wall preprocess twice recess, bellmouth inner wall and socket outer wall are combined closely to two rubber circle, form kneck sealing region, two preformed holes of suppressing of taking the screw thread of symmetry between the two rubber rings of socket end, intraductal lining has the concrete, and outside of tubes portion sets up the anticorrosive coating. The utility model discloses protect to adopt the two rubber rings of socket joint formula sealed, have compliance and elasticity, can avoid the field weld, have connect reliable, construction convenience is swift, maintenance cost low grade characteristics. The inside lining of compound pipe has better sealing performance. Intraductal fluidic can be resisted and the influence is erodeed. The advantage that have anti chemical attack, resistant temperature variation, fluid resistance coefficient is little, the life -span is longer etc. Can not be compared. The ordinary pipe of solution that can be fine receives acidity or the corrosion problems of alkaline substance to the pipeline.

Description

Double rubber ring spigot-and-socket concrete filled steel tube multiple tubes

Technical field

This utility model belongs to common fluid conveyance conduit design and fabrication technology field, specifically double rubber ring spigot-and-sockets Concrete filled steel tube multiple tube.

Background technology

The progress of the fast development with tandem strip mill production and solder technology in recent years, steel pipe obtains at small-bore aspect Quickly popularization and application.Its advantage essentially consist in steel pipe high precision, uniform wall thickness, can arbitrarily scale, burst strength is high, extend The good, vibration resistance of property and impact resistance are good.But also have the shortcomings that very important：Steel-pipe welding is continuous online production, wall thickness Thicker, bore is bigger, and the investment of unit and welder is bigger, and it gets over not economical and practicality；Wall thickness is thinner, Bore is less, and utilitarian function will accordingly reduce.Simultaneously common welded still pipe have the welding of installation process center tap lay time-consuming Arduously, the shortcomings of large-diameter pipe is easily flat.And pipeline materials that other are commonly used on the market, such as steel cylinder concrete drain pipe （PCCP）, armored concrete and concrete drain tile, PVC inner lining concrete or frp lining concrete drain tile etc..These Tubing has been found that different shortcomings in actual engineer applied.This is accomplished by developing, and a kind of to integrate many merits new as the whole body Type body.Double rubber ring spigot-and-socket concrete filled steel tube multiple tubes come from this as a kind of pipeline material vitality that improves.

Content of the invention

The purpose of this utility model is to provide a kind of pair of rubber ring spigot-and-socket concrete filled steel tube multiple tube, and this pipeline connects Reliability, convenient and quick construction, maintenance cost are low, have preferable sealing property.That can resist tube fluid washes away impact.Tool Have resist chemical, resistance to temperature change, the incomparable advantage such as Flow Resistant Coefficient is little, last a long time.

The purpose of this utility model is realized in：Double rubber ring spigot-and-socket concrete filled steel tube multiple tubes, including steel pipe, Bellmouth steel loop, socket steel ring, groove, inner lining concrete and anticorrosive coat.It is characterized in that welding bellmouth steel loop in one end of steel pipe, separately Socket steel ring is welded in one end, and socket end outer wall is pre-machined twice groove and places rubber ring；Double rubber rings bellmouth inwall and are inserted Mouth outer wall is combined closely, and forms seam sealing area, and there is play movement；Symmetrical two band silks between the double cushion rubber of socket end That detains suppresses preformed hole, docks the rear port sealing water pressure test for pipeline；Pipe is lined with concrete, and its intensity is not less than C40；Setting anticorrosive coat outside pipe, takes and epoxide coal bituminous carries out preservative treatment.Described multiple tube is straight tube, reducer pipe, threeway Or four-way.Described number of recesses is 2.Described try screw thread is suppressed preformed hole and is 2.Described bellmouth steel loop one end is welded in steel Pipe port outer wall and, other end most external 30mm flare flue parallel with body.Described socket steel ring and steel pipe horizontal welding Connect, above have 2 road annular grooves and 2 pressurizing ports with screw thread.

The specifically creative technical essential of this utility model：This multiple tube Interface design is that welding is held in one end of steel pipe Mouth steel loop, the other end welds socket steel ring.Between the double cushion rubber of socket end, processing symmetrical above and below two is reserved with suppressing of screw thread Hole, docks the rear port sealing water pressure test for bell and spigot.Joint rubber ring uses the solid cushion rubber of circular cross-section. Twice groove is pre-machined in the socket end outer wall of body, two circular cross-section rubber rings are embedded in groove.When socket end is inserted When entering female end, double rubber rings combine closely bellmouth inwall and receptacle wall, form seam sealing area, this sealing area It is pipe joint water pressure test region.Pipe joint clearance control size 25mm, should seal after the water pressure test is qualified.Multiple tube Inner lining concrete there is preferable sealing property, what its intensity was not less than that C40 can resist tube fluid washes away impact.Pipe is outer Portion arranges anticorrosive coat, takes and epoxide coal bituminous carries out preservative treatment.

The beneficial effects of the utility model：This utility model is made up of steel pipe layer, inner lining concrete layer and outside anticorrosive coat. It is with prestressed reinforced concrete drain pipe（PCCP）Compare the work having cut ring orientation prestress steel wire and cement mortar protective course Skill flow process, remains prestressed reinforced concrete drain pipe（PCCP）Advantage；It increased and hold, insert compared with common steel tube Mouth steel loop and inner lining concrete, construction more saves labor, and avoids the defect of steel pipe simultaneously.The double rubber ring spigot-and-sockets taken connect Mouth mode has pliability and retractility, can exempt Site Welding, has connection reliability, convenient and quick construction, maintenance cost Low feature.The joint sealing test that double rubber ring bell socket modes solve conventional full packages water filling is had the disadvantage that, 2 preformed holes of suppressing with screw thread make that connector test is easy to operate, reliable results.Inner lining concrete solve common steel tube or Ductile iron pipe not acid-alkali-corrosive-resisting the shortcomings of, it has preferable sealing property, and that can resist tube fluid washes away impact. Outside pipe, the anticorrosive coat of setting provides effective protection to steel pipe, improves the decay resistance of pipeline.
