Detailed description of the invention
Referring especially to accompanying drawing, pipeline repair unit 10 constructed according to the invention includes the conduit of plastics or metal material 12, upper division is referred to as two axial limits 11,13.The preferred material of conduit 12 is PVC, but any metal material or mould As long as material material meets functional requirement described here and can use.It is a plate material that conduit 12 forms the initial stage, then Be cut into suitable size, afterwards longitudinal edge 11,13 along the circumference range of pipeline be inclined in 15 and 17 respectively inclined-plane or by Gradual change is thin.The part 15 attenuated is by removing the material formation constituting conduit 12 outer surface from surface, and the portion that is tapered Divide 17 by removing material composition from inner surface of pipeline.In-line (seeing accompanying drawing 6) is installed, gradually when repairing unit 10 Taper portion 15 and 17 is discharged side by side, and after configuration, the pre-conduit of thickness 12 partly that is tapered of discharge side by side is formed and makes Plate of material thickness corresponding.As a result, the thickness of pipeline is being consistent in the range of whole pipeline surrounding.Then at stove Middle heating duct 12 forms the flat board used and reaches its softening point and formed thus close to pipeline to be repaired around mandrel Diameter.If desired with the alternative method (such as, pressing method etc.) forming conduit 12.In any case, formed Step is generally used for pipeline to the state offset opened, and the most tapered part 15 and 17 is placed side by side, such as Fig. 6 institute Show.
At least one rupturable bag 19 comprising adhesion material 21 is placed on the inner surface of conduit 12, and position is tapered in advance Part 15 is adjacent it is preferred that the most thereon.In a preferred embodiment of the invention, multiple bags 19 use accompanying drawing 7,8 institutes The form shown, wherein the bar 20 of plastic material carries a series of bag 19.When these bags are by binding agent or similar east When west is fixed on pipeline, generally rectilinear direction arranged side by side is become to arrange with longitudinal edge 11.The function of adhesion material 21 can adhere to The part that is tapered two 15 and 17 links together, and conduit 12 is fully to open in the installation process repairing unit 10 Thus seal a part of pipeline.Can be configured to rupture by overstocking when in view of bag 19, and institute The position of side can make adhesion material flow out along the part 15 that is tapered.
In order to prevent wrapping 19 too early rupturing during opening at conduit 12, the inner surface of conduit 12 dispose prominent Thing 23, is placed on this position and is possible to prevent the outer surface of pipeline to be ruptured by overstocking and wrapping 19 in conduit 12 opening procedure, Until being tapered, part 15 and 17 just reaches placement location arranged side by side.Mobile order such as Fig. 4, shown in 5 and 6.Outthrust 23 can use a single longitudinal edge, are integrally formed with conduit 12 or adhere on conduit 12 or a series of longitudinal direction Indenture etc. in alignment, and be placed along the bag side in opposite direction with tapered part 15, and wraps 19 phases On adjacent position.
In order to about beam guide tube 12 is at the transport before roll-up state is easy to use and storage, the outer film set of polyethylene Cylinder 25 or the like is placed around pipeline.The diameter of outer film sleeve 25 more much smaller than the diameter opening conduit 12 so that Affined pipeline can be along longitudinally through eligible for repair pipeline.The interior thin film sleeve 27 that similar material is made is placed on to be rolled The respective end heat-sealing of the inside of conduit 12 and two ends and outer film sleeve 25 thus conduit 12 and attachment bag 19 are provided Moisture seal.
Surrounding outer film sleeve 25 on packing ring sleeve 30 circumferencial direction, by class jelly, cohesive material such as improves polymerization Body Colophonium.Packing ring bush material deformable is stretchable without rupturing, so, in the case of conduit 12 fully opens, packing ring Sleeve 30 can stretch along radial direction and former circumferential direction along with conduit 12, and bring is the reduction of thickness simultaneously.Gasket sleeve The conduit 12 that cylinder 30 is eventually opened by the inwall facing to defect tracking part promotes, thus provides conduit and pipe section Between liquid seal.The material of packing ring sleeve 30 can adhere to lead the inner surface of pipe section and can meet appointing of inside The most regular.Preferably take a blame necessity, packing ring sleeve links together with line sections cohesive.
The character of packing ring bush material is that it is prone to bond most surfaces and material.Although this comes for seal washer Say it is advantage, but but show difficulty attempting shipped and pass through pipeline arrival defective part when. Correspondingly, the gauze material with a layer or more layers can be formed as sleeve 31, and limit around spacer sleeve 30 Condition a relative tensioning.The scrim material being generally used for this purpose is the usual type used as packaging material, uses In Fructus Citri tangerinae, the packaging of the analog such as Fructus Vitis viniferae.Such material has relatively tight real surface under constraints, thus due to viscous Property packing ring sleeve 30 effect under make unit to be moved through pipeline in the case of there is no any obstacle.Along with conduit 12 Starting to untie, tulle sleeve 31 is rolled up tighter and embedding is led axially extending that packing ring sleeve 30 is internal.In other words, pad Bush material " flow " and through thin film hole thus by pad hide thus prevent the interference of spacer sleeve sealing function.
Although tulle sleeve 31 should be substantially prevented from transport and storing process maintenance unit and other unit and its He is bonded together on surface, and a layer 33 of release paper can be placed around unit and peel off this layer in a pre-installation.
During operation, with reference to accompanying drawing 9 and 10, unit is placed on arbor assembly 40 and repairing unit 10 is transported to one has scarce The pipeline section fallen into, arbor assembly is arranged on chock 41 in turn.The heart is pulled by the towing device 50 of the translator of common type Shaft assembly thus detection television camera is drawn through sewer line.Generally, such camera (not shown) and arbor assembly 40 are used in conjunction with thus allow the other defect in leak position or pipeline 35 is carried out vision localization.Interchangeable, camera Directly can pull with electric power capstan arrangement on land used with chock unit.Traction machine 50 and mandrel 40 by arbor hole 39 or other Enter entrance and insert main sewer line 35.Traction machine 50 pull-up arbor assembly 40 (and detection camera) passes through blowdown pipeline And move to next arbor hole 37.Monitoring operation car with suitably control and detection equipment is usually located at and arbor hole 37 phase Adjacent ground level, it is possible to the movement to trailer and camera is controlled, and also may be used the injection of fluid under suitable pressure simultaneously To be controlled.
Arbor assembly 40 includes a rigid hollow cylinder manifold 43, by many at gas pipeline 45 inside it The device 46 that arm one section is placed receives gas-pressurized.Multiport 47 determines the cylindrical wall through manifold 43 and usual quilt One inflatable bladder sleeve pipe 49 covers.The two ends of cryptomere sleeve pipe are held, and the relation of the outside liquid airproof of manifold 43, Thus the pressure within manifold, the gas through port 47 makes cryptomere casing expandable.Cryptomere sleeve pipe 49 can be collided make Must repair unit 10 to open, such as Fig. 4, in 5 and 6, order is shown.In the case of major part is open mode, as shown in Figure 4, bag 19 are protected from being ruptured by overstocking of outthrust 23.Along with being tapered, part 17 crosses outthrust 23, such as Fig. 5 institute Show, manifold 43 the radioactivity pressure being applied on the most of position within conduit 12 makes bags burst and along conduit The part 15 that is tapered flow out attachment.When conduit 12 fully opens, as shown in Figure 6, the part that is tapered 15 and 17 is arranged side by side Close on placement, and both can quickly be sticked together by the bonding agent placed between the two.
In the installation process repairing unit 10, fragment is likely to be stuck between repairing unit 10 and pipeline walls.Such as, Fixture block can largely hinder repair unit 10 expand and can very adverse influence repair unit sealing function.In order to Ruled it out, arbor assembly 40 can be used in combination with spraying apparatus 70, uses and places ring around mandrel 43 one end Form, and include that a toroidal conductor is for accommodating pressure (hydraulic) water or other cleaning liquid by delivery conduit 71.A series of Nozzle stretches out from conduit and the angle placed can make Pressurized cleaning fluid wash away the fragment that the inner surface of pipeline flows out.Lead Line and nozzle are all placed on one end of arbor assembly 40, along with moving through pipeline 35 constituent components front end.Accordingly, fragment from It is rushed out at the pipeline walls of mobile arbor assembly front end.The fragment got loose from pipeline walls eventually by common effluent from pipeline Go out.
The mechanism characteristics repairing unit includes that thickness, tensile force and conduit 12 form the elastic modelling quantity of required plate and determine.Example Such as, plate 0.200 inch and being made up of PVC Type 1 material, the intensity being had is about standard SDR35 blowdown pipeline The 64% of intensity, in the case of wherein the thickness of similar material plate is 0.100 inch, intensity is only the 8% of same pipeline.Certainly, In order to avoid the fluid in pipeline to be repaired limits, the thickness of plate must control;But, for the actual (real) thickness of plate, convection cell Limit be only on the order of magnitude of one or two percentage points.Generally, the plate thickness used for unit 10 is 0.200 inch.In order to repair the pipeline that pipe diameter is 8 inches, the mandrel diameters being preferably formed as conduit 12 is about 6 inches. This makes conduit be reduced in size to the level of external diameter about 5 inches, and is packaged in without requiring that excess is along radial direction power In the case of just may be expanded to 8 inches.
The length of conduit 12 is determined by the ability manufacturing equipment.If conduit is prominent, the most any length all may be used To reach.From the viewpoint of reality, length is without more longer, because needs just can be repaired by the longest part than the longest part Pipeline put in.In the case of blowdown pipeline, this length is about 2 feet, the typical entrance in mandrel determine.
Determine the diameter of conduit 12, so be tapered in part 15 and 17 at least the overlap of 2 inches for when repair Reason unit 10 can be glued together by both after installing completely.Tapered part 15 and 17 is generally along the ring of conduit It is 3 inches long in shape dimensional directions.
An aforementioned important advantage for the present invention, specified 8 inches of " drainage tile standard specifications " concrete regulation The internal diameter of pipeline should be 8+/-3/8 inch.This means that the outer shroud mobility scale repaired facility is from 26.31 to 23.95 inches. It addition, the pipeline used would generally be by chemistry or mechanical erosion, so changing the internal medium of pipeline further.Existing Repairing unit in technology can not adapt to this diameter range.The repairing unit of existing invention, owing to allowing finally to open at unit State under the permission slack in lap is provided in tapered part 15 and 17, it is possible to adapt to this Diameter range.
As it has been described above, the purpose of pasting material 21 is that marquis guarantees part 15 He that is tapered when repairing unit and installing The lap of 17 is installed together one integral cylinder of formation or pipeline.Preferred pasting material right and wrong for the purpose Annular monomer, becomes polymer when it exposes in the catalyst.Preferably first it is coated onto when needs adhesion material when It is tapered on the surface on surface 15 and 17.The usual glue of bar 20 on bag 19 is connected in the contact adhesive on pipeline 12 surface On, pipeline 12 is connected final retention place with attachment and connects.Preferably the material of bag 19 is that nylon/metal forming/polyethylene is thin Film bag 19 usually 1 inch wide 2 inches long and be heat-sealed on bar 20.Heat seal is generally along three sides about 1/ 4 inches, but along towards being gradually reduced about 1/8 inch of surface 15, so can wrap by shown in Fig. 5 and 6 modes This side can be made during extruding first to rupture.Under this mode, it may be predetermined that the direction that adhesion material flows out.
Outthrust or sept 23 keep certain space between two connection deploying portion of pipeline, so wrap 19 Would not be too early rupture.Along with opening of pipeline, at the interior thereof of pipeline but bag will not be extruded until tapered portion 17 are divided to leave outthrust 23.Now the pressure on the whole radial direction of built-up mandrel assembly 40 is applied to wrap on 19, so The attachment material 21 along the surface 15 that is tapered can be made to rupture stress.
Once attachment material contacts with the catalyst being coated onto the surface 15 and 17 that is tapered in advance, and polymerization process begins to ?.About 30 seconds it is possible to make connector prolonged expansion thus firm being fixed on need repair pipeline wall on.In two minutes, But, binding agent has obtained enough working strengths and has completed whole installation process.
Different types of bag 19 is used in the scope of the present invention.Key feature has been to provide feature container thus has controlled contained The binding material flow direction when rupturing.Feature is to have enough slight thus holds bonding in handing-over and transportation Agent still must rupture when directly applying the power along radial direction to bag.
In addition to above-mentioned specific pasting material and catalyst, it is also possible to use two points of epoxies.Meeting is wrapped under the conditions of this Containing Liang Ge fluid partitioning district, so the reason of arrangement is when bags burst when, and the mixing of two parts epoxy is also worked subsequently. Solvent-borne type adhesive agent, such as oxolane and Ketohexamethylene can be used for this purpose.But, the action time of this material requires not As previous materials short.
Although shown bag 19 and outthrust 23 are all placed on pipe 12 inner surface adjacent with the part 15 that is tapered, it should reason Unpack and can be placed on the outer surface of the adjacent pipe 12 of the part 17 that is tapered with outthrust as alternative embodiment.
Two indentations 55 (merely illustrating one of them in Fig. 1) define thus location can will be repaired at the opposite side of pipe 12 Unit pulls the cable 57 passing through pipeline.Cable 57 two ends are respectively arranged with an eye 59, (are not shown by the hook of tow cable Go out) adaptability engagement.Two eyes 57 are respectively pivoted in indentation 55, so in the case of the compact arrangement repairing unit, close 12 Connection equipment is stuck between surfaces externally and internally.When expanding into, along with repairing unit 10, the point that inside edge 13 passes cable 57, it is allowed to line The center repairing unit freely fallen into by cable 57, wherein can remove this cable.Before this, eye 59 is blocked by two indentations thus anti- Stop element moves in installation process in annular ring.Cable 57 can be used for the prominent or function of spacer 23, if The suitable bag 19 in collision process when can install with drain 12 that prevents can occur the situations of premature compression.
Outer membrane sleeve, as it has been described above, usually polyethylene film, in Thickness Method be 0.0005 to 0.006 inch it Between;Most thickness is had to prove 0.003 inch.Internal layer membrane sleeve is generally of identical thickness.Owing to installation process being preced with 12 Expansion, the heat seal between thin film sleeve 25 and 27 ruptures, and internal layer membrane sleeve can be gone out outside pipeline by such fluid.Outer layer Thin film sleeve 25 has three basic functions, i.e. become square tube road 12 in a pre-installation;Being dried and providing relatively of pipeline 12 is provided The friction of low coefficient is so that the expansion that can smooth in installation process of pipeline or expansion.
Viscosity packing ring as mentioned above is completely, it is preferred to use improvement polymer pitch, and the lightest material of plasticity can be General 800% is stretched in the case of not rupturing.Such material uses Owens Corning Fiberglas to make.Can not stretch Exhibition packing ring sleeve is usually 0.12 inch.Expanding in installation process along with repairing unit 10, packing ring bush material expands also And effective packing ring thickness being reduced to 0.100 inch thus being formed between duct wall and swelling pipeline 12.Improvement polymerization Any irregular part that body pitch is attached on the sidewall of pipeline and changes on surface.The Alternate materials of packing ring sleeve 30 Can be closed cell foam rubber or other low-hardness rubbers.But, improvement polymer pitch is far from most optimum materials. Improvement polymer pitch shortcoming be it can pay be attached to major part plane on.Certainly when material uses as packing ring, this is individual A little, but material makes to repair unit 10 and moves to the defect location of pipeline and become impossible.Just for this purpose Use thin film sleeve.
As it is shown in figure 1, multiple repairing unit 10 are installed in series or are installed in parallel thus keep in repair relatively long pipe string. It is gradually reduced this function by the end of maintenance unit thus allows another unit that is partially received in of a unit The other end.Just for this purpose, one end cervical region of unit slightly reduce thus can be smooth relative with another unit Side interlocks.
The preferred embodiment of maintenance unit 10 described above is configured to a right circular cylinder.This can cause pipeline to be repaired The end points repairing unit has a small abrupt change (that is, general diameter reduces about 0.25 inch) diametrically.This anti-mistake To be slightly increased flow resistance and flow behavior is demoted;Two ends diameter (that is, the thickness of reduction) may be formed and compare core Smaller pipeline 12, when the unit is mounted, shows from the internal diameter of maintenance pipeline to smooth the internal diameter of maintenance unit 10 Transition.
In installation process, traditional television camera is for being positioned to the defect of maintenance.Maintenance unit is typically connected to slide Installing on arbor assembly 40, then mandrel is moved to the centerline of defect by cable and/or towing device, and this point is by detecting phase Machine is observed.Once arbor assembly 40 is in center, and cryptomere sleeve expansion is to about 90psi, and this can cause repairing unit 10 Expand.Expand repairing unit and and cause rupturing of the bag that is connected on the sidewall of maintenance pipeline.After about 2 to 5 minutes, bonding is by only Good, reach mandrel and can expand the degree moved with principle maintenance station.
The most as described in the background section, prior art utilize a small amount of polymer and felt to be placed on close to pipeline maintainance Band defect pipeline section and being cured between section.If the placement of pipeline has a big section disappearance, only one of which alternative embodiment Prior art can be used.Particularly, the thickness of polymeric thickness and felt lining all must increase and guarantees that material has foot Enough intensity resists the normal power being applied to fault location during using.It is expensive for increasing additional thickness, because whole piece lining In thickness must increase only due to carry out the demand keeped in repair on single point.It is likely to pacify at fault location according to the present invention Fill maintenance unit 10 thus additional structural strength is provided.If this point completes, it is thus only necessary to pipe laying 12 is without installing Packing ring sleeve 30, because the latter need not.
From described above it can be seen that the invention provides a kind of new method and apparatus, wherein the defect in pipeline is permissible At one permanent on the basis of very simple the most easily by maintenance good a lot of times without loss pipeline work.
