Description
The present invention at first relates to a kind of manufacture method that is used for the anchor tube of grouted anchor bar, wherein, from the pipe that exists as raw material of hot rolling preferably, at first in its pore, insert a static mixer, then, a kind of profile of roll forming in tube outer surface, preferably a kind of longitudinal divisions or the screw thread that extends continuously, make pore at least partial cross-section reduce, and wherein, reduce based on described cross section, longitudinally make the static mixer location.
This anchor tube can be seen the member as the boring grouted anchor bar, and they are for example for punching such as in the wall that is fixed on rock mass, in the wall of opencut cavity, in the ground, and is poured in the boring that has constituted by coagulable injecting paste material and fixing thus.The grouted anchor bar of for this reason holing has a drill bit at its front end usually, and in anchor pole inside a central slip casting passage that longitudinally runs through is arranged, and can import injecting paste material by it, and it has towards the outlet in the anchor pole outside at its front end.This grouted anchor bar can have one or a plurality of anchor tubes that connect by clutch are arranged when needing, and they are at its external surface longitudinal divisions or be shaped on spiral thread on anchor bolt continuously.Spiral thread on anchor bolt improves the effect that is connected with injecting paste material on the one hand, and can also be used for being connected and being connected to each other by clutch of anchor pole and drill bit, and can be used for being fixed on the casting head of rear portion.Described casting head has a syringe pipe, for example one or more feed compositions is introduced in the slip casting passage under pressure with irrigation (routine water air or water) and for slip casting in when boring by it.Here, preferred injecting paste material is when several pairs of composition resins, and their two kinds of compositions solidify after the short time contacts with each other.Therefore these feed compositions are supplied with casting head separately, thereby make them just after entering the slip casting passage, or just meet soon before being installed in the expendable part in its end entering one.In order the time to reach the good mixing of these compositions until coming out to enter boring, known in the slip casting passage fixed-site ground settle one or more so-called static mixer.Here it relates to a kind of flow obstacle that is made of so-called deflection plate, and it for example has rib, helix etc. based on its configuration design, impels them to mix when two kinds of compositions flow through.In order to prevent that static mixer from being dragged away together under the flowing pressure effect of feed composition, use different technology.In the prior art, by DE102007005540A1 is known static mixer is rolled in the continuous pore of anchor tube central authorities as input channel that is pressed into the boring grouted anchor bar.In fact, generally use the anchor tube of steel and preferably use plastic static mixer.Pipe is often as the raw material that are used to make anchor tube, and it also has lower interior and outer surface quality and have the size and dimension error in unprocessed reset condition.Especially, as raw-material pipe sometimes in addition have non-circular, for example polygon or even polygonal hole cross section and/or external cross section.The static mixer of expectation must have a diameter, so it can insert in the pore in face of roll-down type vertically.Yet here based on described size and dimension error, be not in the cross section of hole, can reach the little of hope all the time and uniform error, so static mixer can not be pressed in its hole in known manner, and there is the danger that can cause static mixer to be damaged in all grouted anchor bars.
As background, the objective of the invention is, advantageously further develop the method for the described type of preface, thereby avoid above-mentioned shortcoming especially as far as possible basically.
The purpose that proposes at first and mainly combines with following characteristics by the present invention and reaches, that is externally before the profile roll extrusion, insert a sleeve in pore, it vertically centers on this static mixer in the section at one at least in pore, and it has a kind of hardness littler than static mixer.Cause the reason of static mixer axial restraint to be, the cross section that sleeve forms in the pore during by the profile roll forming reduces clamped, and longitudinally be fixed on the hole wall, and reduce at the cross section that with regard to the sleeve inner cross section, itself also stands to a certain degree in this process, reduce to clamp static mixer and longitudinally be fixed on the sleeve lining by described cross section.Therefore, after the profile roll forming, sleeve and static mixer immovably are fixed in the pore, thereby we can say that radially two-stage compresses.By the present invention, sleeve has a kind of than little hardness of static mixer and/or low intensity.The pipe that is used to make anchor tube usually with steel or with a kind of similarly thereby the material manufacturing of higher hardness and intensity arranged.Draw thus or preferably, compare with anchor tube externally, the material of sleeve also has littler hardness and/or lower intensity.Therefore preferably, bush material is compared with the material of static mixer and anchor tube minimum hardness and/or minimum intensity.If preferably use steel anchor tube and plastics system static mixer, then anchor tube can have hardness and/or intensity the highest in all members.By sleeve have on its surface at least a kind of than static mixer and thereby common also low hardness than anchor tube, sleeve has just compensated the illustrated error of preface, can not cause damaging static mixer.The error of the noncompensable pipe of static mixer, can by sleeve based on its than static mixer more easy deformation compensated.Therefore the present invention allows static mixer also can be pressed into still has than in the raw material of mistake or in the anchor tube, thereby can improve the quality of finished product anchor tube on the one hand, and can reduce cost on the other hand.
Preferably, a vertical section that adopts pipe or flexible pipe is as sleeve, and described vertical section preferably has the length identical with static mixer at this moment, but also can be different therewith.Therefore sleeve relates to a part that is independent of static mixer.Also preferably, described pipeline section or flexible tube section have good deformability, so also can be out of shape with hand easily in certain limit with regard to its cross section.In this way, even under the situation that little movement clearance is arranged, still can easily even insert in the non-circular pore and the big error of compensate for slower.In addition preferably, sleeve can have lower modulus of elasticity.Therefore the plastics or the rubber hose of elastically deformable also are well-adapted.Relevant by method of the present invention also preferably, at first static mixer is inserted in the sleeve, then these two parts are put into raw-material hole or pore jointly.Being considered to appropriate is, the outer cross section of sleeve, and its external diameter especially, with the pore cross section before the profile roll extrusion, especially pore diameter is compared, and is onesize or smaller substantially.Combine with it, preferably, use a kind of static mixer, its cross section, its external diameter especially, with the hollow cross-section of sleeve, especially internal diameter is compared, and is onesize or smaller substantially.In this case, even adopt the sleeve that enough dimensional instabilities are arranged, still sleeve might be inserted in the pore with the static mixer of inserting wherein, this pore cross section before the profile roll extrusion for example is non-circular (for example polygon or polygonal), and it may longitudinally not be straight also.Therefore, in order to make anchor tube, also can use following these pipes as raw material, they that is also at external surface, constitute non-circular (for example polygon or polygonal) border generally.Preferably can adopt a kind of static mixer, it has helical segment longitudinally adjacent and that reverse each other along circumference, and its preferred rib shape outer edge is on imaginary cylindrical enveloping surface.Especially when static mixer its outward flange have the band corner angle or even during sharp-pointed seamed edge, then they can be cut in the softer sleeve in a small amount when rolling or during the profile roll extrusion, thus additionally compensating error and axial restraint better.One of this method is appropriate further develops regulation, and static mixer and sleeve are inserted in the pore, and the free end section of pore is maintained the original state.Next step of method can be, the described end section of pore preferably after the profile roll extrusion, preferably enlarges its diameter by boring, and then in Surface Finishing.Described processing can especially be carried out at independent end processing station, and the smear metal that produces in when section processing end can be from opposite side, that is passes fixing static mixer and blow out.Have possibility in addition, the frictional fit formula is pressed into the anterior at least vertically section that slip casting is taken over vertically in the end section that enlarges, and it has an internal cavities, is used to import independent import and an outlet that is located on the anterior vertically section of the different feed compositions of anchor pole.Vertically hold from the rear portion that pore stretches out in the slip casting adapter, a protective cover can be installed when needing.This anchor pole and the combination that is pressed into slip casting adapter wherein in the distolateral formula of frictional fit vertically also have independently meaning in framework of the present invention, that is to say, and also be significant even without other features of having enumerated.Take over the assembly that constitutes pre-assembled in enormous quantities by anchor pole and slip casting, warehouse-in supply casting head then, this casting head be used to the to hole boring and the slip casting of grouted anchor bar are particularly useful for automated job.According to the desired design that slip casting is taken over, it can for example be inserted in syringe pipe rotatable inner one with its rear portion vertically in the hole of section geometric match.
In addition, the invention still further relates to a kind of anchor tube that is used for grouted anchor bar, in a kind of profile of its external surface roll extrusion, preferably longitudinal divisions or the screw thread of extension continuously, an and static mixer in its pore, the partial cross-section at least that causes when the profile roll extrusion based on pore reduces, and longitudinally is positioned.
Prior art from preface is mentioned the objective of the invention is, and advantageously further develops this type of anchor tube, thereby avoids illustrated shortcoming especially as far as possible basically.
The purpose that proposes at first and mainly combines with following characteristics by the present invention and reaches, that is static mixer is vertically centered on by a sleeve in the section at one of static mixer at least in pore inside, sleeve has a kind of hardness littler than static mixer, and, sleeve and static mixer, reduce based on the partial cross-section at least that causes when the profile roll extrusion, longitudinally be positioned.Regulation preferably, the material of sleeve has a kind of than little hardness of the material of static mixer and/or low intensity, but it is also enough to provide corresponding classification about the surface of contact thus.About effect and the advantage and associated possible the further developing that can obtain by the present invention, can be referring to front and follow-up explanation.Especially preferably, adopt pipeline section or flexible tube section as sleeve.Preferably there is this possibility, that is, makes up static mixer made of plastic and the sleeve made from plastics or rubber.Especially flexible plastic flexible pipe is suitable for, and can make its cross-sectional deformation with hand.Also thinking appropriate is that sleeve has identical length with static mixer.Relate to static mixer preferably, it has helical segment longitudinally adjacent and that reverse each other along circumference, and the outer edge of its preferably rib shape is on imaginary cylindrical enveloping surface.Static mixer and sleeve can be inserted in the pore, and the end section is maintained the original state.The frictional fit formula is pressed at least one anterior vertically section that slip casting is taken over vertically in this end section, and it has an internal cavities, is used to import independent import and an outlet that is located on the anterior vertically section of the different feed compositions of anchor pole.Described slip casting is taken over can preferably use plastics, preferably uses the polyamide manufacturing in addition, especially whole as plastic pressure injection spare.

2Its diameter D
2With diameter D
1Compare onesize or smaller substantially.By the example of selecting, not Yuan pore diameter D
1Be about 12-13mm (also relevant) with the direction of measuring, and diameter D
2Be 12.5mm, this moment, the wall thickness of sleeve 5 was 1.25mm.
Fig. 3 represents the so-called static mixer 6 by a kind of preferred form of implementation.It uses the plastics manufacturing, makes with polyformaldehyde (POM) in this concrete example, and its yield stress is at about 65-75N/mm
2In the scope.Therefore in this example, the material of static mixer 6 has the intensity higher than the material of the plastic flexible pipe of sleeve 5.All-in-one-piece generally in this example passing through disconnects the static mixer 6 that shortens expression, and it is 600mm that total length is arranged, and 48 so-called deflection plates 7 of L front and back layout are longitudinally wherein arranged.Each deflection plate 7 is made of two helical segments 8 that reverse 180 ° of angles in same vertical section each other, and they itself respectively extend along half circle.The deflection plate 7 that longitudinally L is adjacent respectively has reverse pitch, and around longitudinal axis each other angle stagger 1/4th the circle, longitudinally L is through-flow so this structure allows.The rib shape outward flange 9 of helical segment 8 has the seamed edge of band corner angle, and here, the outward flange 9 of helical segment 8 is on the imaginary cylindrical enveloping surface 10 of dotted line hint among Fig. 3 and the 3a.In selected example, static mixer 6 has an outer diameter D

3Equally be about 10mm.Yet should be pointed out that in above-named all sizes that the proportionate relationship of diameter and they especially also can be different in framework of the present invention.Compare with the plastics of selecting for static mixer 6 for the plastics that sleeve 5 is selected, have less hardness and easy deformation more.
For be manufactured in the Figure 4 and 5 as first kind of preferred form of implementation represent by anchor tube 1 of the present invention, at first static mixer 6 being inserted has in the sleeve 5 of same length in this example, passing through in distolateral hole 11 part 5,6 of these two mutual facies suite inserts longitudinally together then, L inserts in the pore 3, and in pore 3 from managing the 2 distolateral segment distance A that move inwards, end section 12 is maintained the original state.Though pore 3 has shape and scale error and depends on the diameter D of selection
1To D
4Little sideshake, but based on the low hardness of sleeve 5 and the size relationship of intensity and above-mentioned selection, sleeve 5 and static mixer 6 still can successfully be inserted, the lengthwise position in being also illustrated in Fig. 5.In the next procedure of method, roll extrusion profile 13 in pipe 2 external surfaces 4 is designed to trapezoidal spiral thread on anchor bolt 14 here, and the professional knows this technology that is applicable to thread rolling.Fig. 4 represents the partition 15 and the groove 16 of spiral thread on anchor bolt 13 visually, and only spiral thread on anchor bolt 13 is represented in signal drawing simplifiedly in Fig. 5 to 7.The rolling of spiral thread on anchor bolt 14 or roll extrusion are carried out under the situation of pressurization, and it causes compression to a certain degree and reduces thus transverse to the vertical pipe cross section of L orientation.Especially, also cause the partial cross-section at least of pore 3 to be dwindled by the distortion that produces here.Fig. 5 represents with the sectional view of simplified schematic, the inner surface 17 of pore 3 is owing to the cross section that causes by roll extrusion dwindles, abut on sleeve 5 outsides with flushing now, in this case, the shape and size error in hole 3 (Fig. 5 do not draw expression), by softer sleeve 5 by corresponding local distortion compensation.There is possibility according to the roll extrusion condition, or only in the zone of thread groove 16, or, cause pore 3 contraction or cross section to a certain degree to dwindle along whole screw thread.Here, diameter D
1To D
4Be tuned as each other and with roll extrusion condition and sleeve 5, make the constriction of pore 3 also cause some compression of sleeve 5 and cause dwindling of its hollow cross-section, that is cause dwindling its inside diameter D
3Therefore, the inner surface 18 of sleeve 5 radially inwardly is pressed against on the rib shape outward flange 9 of helical segment 8 of static mixer 6.Here, therefore the less sleeve 5 of hardness ratio allows that also some distortion is arranged in its wall, by this deformation-compensated error.Obviously, sleeve 5 is fixed in the hole 3 by L longitudinally now by the clamping force that produces from the outside, and static mixer 6 longitudinally is fixed on the sleeve 5 by the clamping force that produces when the roll extrusion from the outside, therefore finally also relates to pipe 2 itself.If when profile 13 roll extrusion, cause cross section to dwindle, this cross section dwindles greater than being axial restraint sleeve 5 and static mixer 6 necessary contractions, then sleeve 5 allows helical segment 8 outward flange 9 that it is sharp keen to be pressed into or even may to cut in the inner surface of sleeve 5 based on its hardness lower than static mixer 6.Prevent in this way otherwise the damage of possible static mixer 6 or even possibility explosion.
Fig. 6 represents the anchor tube 1 according to another kind possible processing step by the preferred development design of the inventive method.Here, the original diameter D of pore 3 end sections 12
1, in selected example, slightly increase and then fine finishining by boring.Meanwhile carry out the processing of end face 19, make it as representing among the figure, to make the plane.
Fig. 7 represents as preferred other possibilities, and the frictional fit formula is pressed into slip casting and takes over vertically section 20 of a front portion of 21 vertically in the end section 12 that enlarges.Described slip casting takes over 21 an internal cavities 22, it has ready independent import 23,24, be used for supplying with the different feed composition of anchor pole 1 when the slip casting operation, and the outlet 25 that exists on the forwardly vertical section 20 is arranged, its imports as in the pore 3 of slip casting passage.By fine finishining, the diameter of end section 12 and slip casting take over 21 vertically sections 20 external diameter match for, or with set there Fig. 7 not in detail the external diameter of the annular crosspiece of the axially spaced-apart of expression match for, make and take over 21 and need with big pulling force in order to extract slip casting from anchor tube 1.This peripheral hardware rear portion is section 26 vertically, so that at the casting head that is used to import feed composition (for example two kinds of compositions of two composition resins), at an internals place that drives rotation, enter with it in how much adaptive holes, thus with ready import 23,24 and feed composition independently conveyance conduit export and align.By its anchor pole spiral 13 is screwed in syringe pipe drives the screwed hole that matches in the internals of rotation, can realize that the torsion pass of anchor pole 1 connects.Described slip casting is taken over 21 another particularity and is, its import 23,24 still is designed to the specified breakdown point that wall thickness reduces and seals before using for the first time.Just just break when pressurizeing by irrigation or the composition by use slip casting material, here, the elastic recoil clack valve is played in the wall district of the cross section wedge shape of adjoining.Cavity 22 forwardly constitutes in the section of axial boundary by ring-shaped step 27, another independent static mixer 28 of packing into.It does not need further fixing, that is to say that especially also not needing to take over 21 clampings with slip casting is connected.Different with it, its axially-movable is backward by ring-shaped step 27 restrictions, and is subjected to 6 restrictions of independent static mixer forward, make it with respect to the position of anchor tube 1 with introduce previously the same fixing.
