Description
Technical field
The present invention relates to a kind of for being rebuild the method for pipe well, the lining manufactured in this way and for manufacturing the device of lining by lining。
Background technology
Drainage system especially well is under different heat, chemistry and hydrological load。Additionally, higher enterprise's load is defined significant contribution by industry and medium-sized and small enterprises。Such as be normally introduced into a large amount of material corroded especially by dairy, brewing industry or by chemical business, described material itself or by with being blended in flowing and trigger chemical reaction of the material of other appearance。
The higher energy level that described dirty goods and waste water (such as flow into the violent flowing caused) after flood by high waste water works to strong wear with being associated chronically。The surface corrosion of architectural process eventually passes a large amount of damages causing carrying material many years。Sometimes defining significant crackle in building, this such as occurs through the joint between well ring of being everlasting。Occurred that the foul water of increasingly volume enters surrounding from channel system on the one hand by crackle, bring corresponding breadth effect, water outside on the other hand such as when subsoil water level rises also penetrates, and sewage disposal device is also brought extra load by this。Both continuously facilitate corrosion。The channel system with this damaged condition is extrahazardous and is that eager needs is rebuild。
In order to rebuild described channel system especially well construction, according to prior art discloses diverse ways:
Depict the mortar of the fixing material with blended cement as classical method, but it lacks lasting stability at this。Using reacting resin layer to be also problematic in that, can peel off from substrate because being laminated under load formation。Although with lamination can sealing surfaces and protect building, but bearing capacity and the static(al) of building can not be rebuild by relatively thin cement or resin bed。
Therefore also disclose that the plate with being managed by the synthetic material (GfK) of glass fiber reinforcement or bending serves as a contrast to pipe well。This GfK material is distinguished by heating, cooling and shape retentivity and the resistivity to chemical agent。Because thermosetting plastics composite material components is insensitive to the material of acid and similar erosion, so it is the suitable material for rebuilding, enable in particular to while comprcssive strength increases, manufacture the parts with higher wall thickness and complex geometric shapes。Disadvantage is however that and need batch production troublesomely have plate to be trimmed and can not be loaded in the sewerage system existed by pipe without any problems。
Therefore other method proposes in described flexible pipe row introduction channel system, to be pressed onto on conduit wall by means of compression air and last ultraviolet light source hardens。DE3922351A1 describes a kind of for the method for trimming waste stream pipeline when using the interior pipe of hardening for this, and this interior pipe enters axially in involved channel section and undertaken folding and with after-hardening by extensile bubble。The lining flexible pipe of the tubulose manufacturing random length is disclosed by DE4326503C2。But this lining flexible pipe is not suitable for branch and pipe well especially preliminary shaft, it is tapered especially to a great extent。The additional seal body that DE19702649A1 research arranges by means of pipe seals branched pipe, thus complete the sealing of connecting line with trimming package。But this method is not suitable for use in the sealing of pipe well。
The theme of DE69925045T2 is to seal with flexible pipe and strengthen the lining device into hole wall, and interconnective by weld seam by least three and intermediate position sealed liner the position of this flexible pipe forms。
Being disclosed the flexible pipe of a kind of multilamellar and for the method for its manufacture by DE102009050084, this flexible pipe can be used in trimming and lined ducts。Flat membrane, to keep identical diameter to be continuously manufactured by, in the welding of the longitudinal edge place of its overlap and is pulled out by assembling pipe by flexible pipe for this。Being arranged on assembling pipe with longitudinal band of resin dipping, described longitudinal band pulls out together with the inner flexible tube formed by flat membrane and should be connected with each other after tube end simultaneously。
Finally, described in DE69702876T2 and illustrate the synthetic material lining for hand-hole and the method for its lamination。Described lining is made up of the sack being initially introduced into flat molds there, and it is inflated after loading hand-hole, but wherein in the changeover portion of taper, kneading region and fold are formed is inevitable。
Summary of the invention
The task of the present invention is that a kind of system for rebuilding pipe well is described, is used for realizing following target:
-leak position is sealed,
-form surface that have resistivity in physics and chemistry, that can well clean,
-improve the stability of well, the especially stability in ferrum stirrup region。
According to the present invention, it is used for solving described task by the method described in claim 1 and by the feature of the device described in claim 12。The scheme of being advantageously improved is the theme of dependent claims。

As already mentioned, described mould 38 is configured to hollow body, and this hollow body is made up of mutually arranged module, and the size (length, diameter, cone angle) of described module is corresponding to the channel shape having lining to be assembled。Shown example illustrates the big cylindricality module 38-1 of the lining of the well ring 14 for upper and lower vertical pile, and its length is equivalent to the well depth in the column regions (referring to Fig. 1) being connected upwardly on berm 18 and is usually the several times of diameter。The module 38-2 connected, for manufacturing the liner segment of the preliminary shaft 12 for taper, is connected to the little cylindricality module 38-3 for neck seal closing part in this liner segment。Mutual tactic module 38-2,38-3 can not be connected with the end of the closing of cylinder 102 via the coupling element 112 of positive with the relative rotation according to Fig. 4。
Of course it is also possible to such as by combining different modules or forming the lining for other well cross sections by means of polygonal module 38-1 '。
Figure 4 and 5 describe to the module 38-1 that major general is big and are divided into two or are divided into four circle segments 118 here such that it is able to change the scheme of diameter。It is bearing in the guide 122 stretched out from cylinder 102 by means of at least one foot 120 radially-inwardly stretched for each section 118。Radially infinitely, such as with the ratio (referring to Fig. 5) of 2:3 described section 118 can be adjusted by this way such that it is able to form the nominal diameter that at least two is adjacent along the direction of the arrow drawn。
In order to close the gap between described section 118 in the state of radially removal, it is possible to arranging the bridge joint sections 124 of arch shape, described bridge joint sections is hinged in adjacent section 118 with end 126。Can realizing the radial direction adjustment of described section 118 in the way of motor driving, this does not illustrate further。
Described mould 38 is movably supported on axle 100 via cylinder 102。Thus, its end on the right of Fig. 4 be freely and can in order to manufacture heteroid lining 50 and to the mating shapes of corresponding existence in preliminary shaft 12 region。
Fig. 2 schematically shows the method for manufacturing lining 50 by means of mould 38。First by inflatable tubular film 40(Fig. 7) to move on mould 38, this tubular film has protection mould not by the task of jointing material infringement, thus finally can pull out the lining 50 formed。Described tubular film 40 feathered in the neck area of taper (gefiedert), namely longitudinally cuts from free end, clings the overlapping region in this formation subsequently from the outside。It also is able to make prefabricated thin film blanking be bonded with each other。
The coiler device 130 being arranged in side illustrated in figure 6 carries the roller 44 of the band 46 of extendible weaving, is generally made up of glass fiber material, and described roller can relative to the axis of mould 38 with different angle of inclination winding moulds 38。Coiler device 130 has slide 132 in the example of fig. 6, and this slide carries roller 44 and the direction along the arrow W of Fig. 4 longitudinally can move back and forth relative to device 20。
Scheme or replacement scheme as a supplement, it is also possible to longitudinally axially insert the band 46 ' of extensile weaving。This is configured to fillet in fig. 2；Replace and also be able to use wide band 46 ', wherein have one, two or three bands covering regions slightly more more than the periphery of mould 38 respectively。In multiple positions, stagger mutually in described overlap circumferentially direction, gathers thus getting rid of material to a great extent。
Axial arranged not extensile and thus tension longitudinal band 48 ensure that the complex formed combination vertically and resists the action of gravity of lining 50 when assembling in the well 10。Longitudinal band 48 of described tension can be derived via the neck member of taper, thus simplifying the suspension of the lining 50 formed and toward the loading in pipe well 10。Can being worked in spool by the blanking 98 of weaving in the region of the preliminary shaft 12 of taper, the shape of this blanking is corresponding to the conical surface of preliminary shaft 12。
Described band 46,46 ' and 48 and blanking 98 are overlapping, thus form the complex of dimensionally stable for lining 50。Wall thickness can coordinate the different load stress in different well depth to be constructed differently to size。
After manufacturing the described complex for lining 50; to the band 46,46 ' of this complex and blanking 98 is dried or preferably flush, namely with resin dipping be wound disposing in other words; it is besieged that this complex utilizes the protection of outside to overlap 52; the breadth of the more solid thin film that the material that this protection set cannot be penetrated by the ultraviolet sealed is made forms, for instance the laminated film being made up of PA and PE。In order to make lap position minimize and wide as far as possible for protecting the breadth circumferentially direction of set 52 to be wound up into complex, cover overlapping portion by adhesive tape subsequently。What the protection set 52 that mechanical aspects is firm ensure that one for lining 50 can the GFK complex of higher load and define locking layer and prevent fluid and gas from entering in pipe well 10。
Describe the bonding jumper 55 that is preferably made up of aluminum adhesive tape in fig. 11 to overlap on the outside of 52 when 0 °, namely in the protection that is loaded vertically in position to be axially located at through vertical line and the place not interrupted by the cone of preliminary shaft 12 from bottom to top of lining 50。This is capable of the wall thickness after hardening with lining 50 in each well height of eddy current measurement equipment Inspection。
Knowing from Fig. 4, presently described mould 38 can slightly reduce at diametrically, radially-inwardly adjusts described section 118 for this such that it is able to removes the GFK lining 50(made vertically via the free end of mould 38 shown in phantom)。
Fig. 7 illustrates and is loaded in pipe well 10 by GFK lining 50。First on the height of the bottom of lining 50, it is mounted with to fill up the plate 54 of well cross section as work platforms and assembling auxiliary。It is then able to such as pass through adhesive 82(referring to Fig. 9) the fixing plate 56 in the grid in the structure later having two pass to be assembled or single track of ferrum stirrup 36 is temporarily fixed on the borehole wall 34。On the borehole wall 34 just on berm 18, in concrete well, the lower section of nethermost joint 38 between nethermost well ring 14 and berm 18, is mounted with the lasting resilient sealing member 60 surrounded。This illustrates the sealing between well lining 50 and the borehole wall 34。Internal tubular film 40 uses pressure-tight sack 66, by rope 78, dish 62 is sunk in sack subsequently, this dish in the end nethermost position is supported on the plate 54 on ladder (berm) 18, when GFK lining 50 occupies institute position set in advance in well 10。
Upper end lid 64 pressure of described sack 66 is sealed shut。Described lid has for importing the interface 68 being in medium under superpressure, preferred compressed air such that it is able to inflate to sack 66。Additionally, described lid 64 has for preferably via for inputting the cable 72 of ultraviolet or the source of infrared radiation 74 or if desired for leading to the opening 70 of another opening importing heat energy of the cable of digital camera。
The GFK lining 50 being ready for installing sinks in pipe well 10 now in the way of being suspended on lowering or hoisting gear 76 so that its shape is consistent with well shape in height and position of rotation。Subsequently by superpressure expansion sack 66 so that GFK lining 50 is opened and straitly abutted on the borehole wall 34, the sealing ring 60 of lower end and fixed disk 56。It is supported by dish 54 by the power on Overpressure to dish 62。The pressure being applied on lid 64 is born by following dish 62 by the rope 78 axially across sack 66。At this, described dish 62 enters in the position of the central authorities within well 10。Connect for hardening the radiation source 74 of GFK lining 50, and by means of its supply cable 72 on rope 78 along up and down motion, until lining 50 hardens。At this, described radiation source 74 moves approximately along the axis of lining, thus ensure that uniform hardening on all positions。
If GFK lining 50 hardens, then regain superpressure and disconnect radiation source 74。After removing the lid 64 with radiation source 74, dish 62 and sack 66 below can pull out by means of rope 78 and remove plate 54。At this, also tubular film 40 is taken out。Finally separate the end stretched out above and below of the protection set 52 of lining 50 and outside。
Figure 7 illustrates the refurbished pipe well 10 with final lining 50。
In order to fix ferrum stirrup 36, there is multiple scheme。According to Fig. 9, the identical scale designation installation site that people use when mounting plate 56 in advance with people on the inner surface of GFK lining 50。So the fixing hole being used for ferrum stirrup 36 is squeezed in fixing plate 56 by people。Described ferrum stirrup 36 can be fixed with bolt and blind nut 80, and this blind nut is arranged on after fixing plate 56。The fixing plate 56 hidden by lining 50 can have little permanent magnet 128 for its location equipment。
As an alternative, there is scheme illustrated in fig. 11, replace the fixing plate 56 between the borehole wall 34 and lining 50, when manufacturing lining 50, female for tool fixed disk 53 is joined between described lining and outer jointing jacket 52。This continues to be illustrated to 20 according to Figure 17 below。
