Abstract

The spacer is constructed by piling a second wedge shape member having inclination of predetermined angles on a lower surface on a first wedge shape member having inclination of same angle on an upper surface. The spacer is inserted in the opening between an inner wall surface of the existing pipe and an outer circumference of the regenerating pipe in A direction to set a member by engaging the same with the regenerating pipe. Locking teeth are formed on inclined surface of the member not to allow movement in a opposite direction to the insertion direction when the member is pressed and is moved in an insertion direction in relation to the member. When the member is moved to locking position respectively, height of whole spacer gradually increases in fine pitch one by one, position adjustment of the regenerating pipe to the existing pipe can be simply done.

Position adjustments distance piece and regulate to repair the method for pipe position with it

Technical field

The present invention relates to repair the distance piece of managing the position to regulate in a kind of gap of inserting between existing pipeline and the reparation pipe, and relate to the method that this distance piece of a kind of usefulness is regulated the position of reparation pipe.

Background technology

The method that is used to repair existing pipeline such as soil pipe is known, wherein repair pipe and be laid on existing pipe interior, by in the gap of repairing between pipe periphery and the existing inner-walls of duct surface, fill filler, this filler that hardens is configured to clad pipe then.The repair of this existing pipeline requires the fixed and repaired pipe usually, this is to repair the pipe position to the position from offseting downward slightly with existing pipeline concentric position by regulating along the upper and lower, left and right direction at existing pipe interior, makes the bottom of the existing pipeline of following end in contact of repairing the pipe periphery realize.

This purpose is to make the bottom of repairing pipe as much as possible near the bottom of existing pipeline and the filler on thickening and the enhancing upside by the bottom that reduces the reparation pipe, guarantee that fluid flows at existing pipe interior, this is because the great majority damage of existing pipeline is occurred in the upper portion of pipeline.In this structure, need carry out above-mentioned position adjustments so that will repair pipe depresses, this is because repairing pipe is to be made less than the plastic material of filler by proportion, and therefore can float on the filler unfavourably.

Repair the pipe position and utilize following method to regulate traditionally, that is, the rectangular member of wherein making desired height (thickness) places the gap of repairing between pipe periphery and the existing inner-walls of duct surface as distance piece.In addition, the open No.2003-286742 of Japan Patent discloses a kind of method of repairing the pipe position of regulating, the bolt that wherein will constitute distance piece is screwed to and constitutes on the module (block) (sections (segment)) of repairing pipe, make that bolt can be from repairing direction that the pipe periphery stretches out and advance or retreat at its rightabout, and screwed to increase or to reduce this bolt from repairing the length that the pipe periphery is stretched out.

Yet, in the method for above-mentioned use rectangular member, must prepare several rectangular member according to the gap size of repairing between pipe periphery and the existing inner-walls of duct with differing heights size as distance piece.In addition, in the situation of the distance piece that comprises bolt as mentioned above, must make screwed hole for bolt is entered in the module that constitutes the reparation pipe, but also must in downstream, block this screwed hole.No matter all there is the pipe position problem consuming time of repairing of regulating in which kind of mode, and can not be easy and the short time in carry out position adjustments.

Therefore, the purpose of this invention is to provide a kind of position adjustments distance piece, this distance piece can suitably be regulated in the repair of existing pipeline and repair the position of pipe at existing pipe interior, and a kind of position adjustments method of utilizing this distance piece also is provided.

Summary of the invention

Insert in the gap that has now between pipeline and the reparation pipe according to distance piece of the present invention, repair the position of pipe to regulate, and comprise: with first wedge of predetermined angular inclination with respect to existing pipeline; Second wedge, it tilts with the angle identical with the angle of inclination of first wedge and is overlapping with first wedge under the state of angle of slope surface contraposition; And blocking device, thereby this blocking device makes second wedge can move and can second wedge can not be moved in the opposite direction in the place's locking of a plurality of locked position of couplers towards first wedge on direction of insertion.Second wedge moves to a place in a plurality of locked position of couplers successively, increases the overall height of distance piece with stepping ground.

Method according to adjusting reparation pipe of the present invention position has been utilized this distance piece that comprises first and second wedge.At first, under the overlapping state of second wedge and first wedge, whole distance piece inserted existing pipeline and repairing in the gap between the pipe.Then, second wedge pressurized on direction of insertion, and make it to move towards first wedge so that with the overall height stepping of distance piece increase continuously and carry out the needed height of position adjustments with respect to existing pipeline repairing pipe.

The present invention can utilize extremely simple steps to be increased to Desired Height by the overall height with distance piece to carry out position adjustments.That is, second wedge only moves with respect to first wedge on direction of insertion.This just makes position adjustments carry out very easy and at short notice.Particularly in the repair of existing pipeline, it is desirable to regulate the position of repairing pipe with respect to existing pipeline in vertical direction; This position adjustments is carried out in easy and short time, and need not carry out any specific step in downstream.In addition, because distance piece includes only two class components, i.e. first and second wedge are so can make distance piece easy and at low cost.

Further aspect of the present invention, its characteristic and various advantage will from accompanying drawing and of the present invention below become more obvious describing in detail.

The specific embodiment

Will describe relevant in existing pipeline rehabilitation work, the adjusting now and repair the embodiment of pipe in existing pipeline such as the position of soil pipe inside.Although existing in this embodiment pipeline and reparation Guan Jun are described as cylindrical pipe, but the present invention even also be applicable in this case position adjustments, promptly wherein desired pipeline (prospective pipe) be orthogonal to this pipeline longitudinally shape of cross section be non-circular situation such as rectangle.In addition, the present invention also is applicable to this situation, and the shape of cross section of promptly wherein repairing pipe is not the shape of sealing, as the pipe on the letter, but in the shape of a side opening, for example shape of a hoof or semicircle.

In the existing pipeline rehabilitation work of this embodiment, as Figure 11 and shown in Figure 12, the reparation pipe 3 that external diameter is slightly smaller than the internal diameter of existing pipeline 4 (such as soil pipe) is layed in existing pipeline 4 inside.This laying is undertaken by connecting annular duct member 2 in the vertical continuously, and this duct member forms by connecting a plurality of sections 1 in a circumferential direction.

Fig. 1 illustrates the entire upper surface of this sections 1.Fig. 2 illustrates the side surface that the arrow C direction from Fig. 1 is seen.Fig. 3 is the sectional view along the A-A line intercepting of Fig. 1.Fig. 4 illustrates the soffit of sections 1.

Sections 1 is corresponding to one of a plurality of parts of the duct member 2 of five equilibrium in a circumferential direction (as, five five equilibriums), and integrally formed by transparent plastic.Sections 1 comprises: have Rack and spend the inner panel 101 that bends to arc with predetermined angular as 72; Along the vertically outside side plate 102 and 103 that is provided with of two lateral edges of arc; Along the vertically outside

end plate

104 and 105 that is provided with of two end edge of arc; And High back of the body gusset plate 106 and low back of the body gusset plate 107In two every kind, each gusset plate is all vertically to outwards being arranged on the inner panel 1.

On the two-end part of inner panel 101, form two opening 101a.Its objective is from the work (with reference to figure 8 and Fig. 9) of inboard execution with attachment bolt 6 mutual fastening sections 1.

A plurality of (being 14 here) bolt hole 102a and 103a are formed in side plate 102 and 103 with the circumferencial direction of prescribed distance along above-mentioned arc respectively.Its diameter is slightly smaller than the diameter of nut 10 or the diameter of bolt 9 heads, to be coupled to each other duct member 2 in the vertical, as shown in figure 10.

In order to insert attachment bolt 6 (with reference to Fig. 8 and Fig. 9), in each

end plate

104 and 105, form

bolt hole

104a and 105a on the circumferencial direction of existing pipeline, to be coupled to each other sections 1.In addition, as shown in Figure 7, V-shaped groove 104c is formed on the middle part on end plate 104 outer surfaces; And be formed on the lower end part of end plate along broadwise by the auxiliary section 104d that the projection of the groove of upside and downside constitutes.In addition, have separately respectively with the jut 105c of groove 104c and auxiliary section 104d relative shape and auxiliary section 105d and be formed on relevant position on end plate 105 outer surfaces.

Gusset plate 106 and 107 has been strengthened the mechanical strength of whole sections 1, wherein be formed with a plurality of bolt hole 106a and notch portion 107a, be used for inserting bolt 9 (with reference to Figure 10) so that connecting tube parts 2, their position corresponds respectively to the bolt hole 102a of side plate 102 and 103 and the position of 103a.The diameter of bolt hole 106a just is a bit larger tham the diameter of bolt 9 bar portions, but less than the diameter of bolt 9 heads or the diameter of nut 10.

In addition, for the inner surface that prevents side plate 102 and 103 and the both side surface of gusset plate 106 and 107 deform, a plurality of laterally overhanging pimple plate 102b, 103b, 106b and 107b are formed on the inner surface of side plate 102 and 103 and on the both side surface of gusset plate 106 and 107 (only forming on a side surface of a gusset plate 107), thereby they alternately are in the position between bolt hole 102a, 103a, 106a and the notch portion 107a of adjacency respectively.Shown in Fig. 5 (auxiliary view of arrow D direction among Fig. 1) and Fig. 6 (along the sectional view of B-B line intercepting among Fig. 1), described pimple plate forms right-angled triangle, and its base is connected with inner panel 101.These pimple plates form this shape in order that avoid reinforcing bar in the situation of the clad pipe that the reinforcing bar (not shown) is made of existing pipeline 4, reparation pipe 3 and filler with reinforcement along the circular in a circumferential direction laying of inner wall surface that has pipeline 4 now.

In addition, as shown in Figure 6, along the lateral edges of inner panel 101 and stride across its total length, auxiliary section 102c is formed on the bottom of side plate 102 outer surfaces, and wherein upside is a groove and downside is a jut; And has the bottom that is formed on side plate 103 outer surfaces with the auxiliary section 103c of auxiliary section 102c negative shape.

Comprise in the existing pipeline rehabilitation work of sections 1 of above-mentioned structure that in use at first sections 1 is sent in the manhole 5 that is communicated with existing pipeline 4, as shown in figure 11, but the attachment bolt 9 of duct member 2 is fixed on the sections 1, as shown in figure 10 in advance.

For set bolt 9, at first with bolt 9 from one of the side plate 102 of sections 1 and 103, as, side plate 102, bolt hole 102a insert, pass the bolt hole 106a of gusset plate 106 and 107, the notch portion 107a and the bolt hole 103a of side plate 103.Then, the head of bolt 9 is inserted into the position of the gusset plate 106 on its contact side plate 102 1 sides.Further, by from the tip one sidespin nutting 10 of side plate 103 outwardly directed bolts 9, nut 10 is tightened to position of the gusset plate 106 on its contact side plate 102 1 sides and by further inserting cylindrical keeper 19 and this keeper is inserted into the position of the gusset plate 106 on its contact side plate 103 1 sides from the most advanced and sophisticated side of bolt 9, fixes bolt 9.Keeper 19 is positioned to bolt 9 concentric with bolt hole 103a and aligns mutually with bolt hole 102a that connects good duct member 2 and the position of 103a, and is as described below.

And the quantity of the bolt 9 that is fixed is less than half of the quantity of bolt hole 102a etc., for each bolt hole or for to fix a bolt 9 every the bolt hole of a plurality of quantity.In addition, the length setting of bolt 9 becomes: the bolt 9 that is fixed is slightly smaller than the width (outer surface from the outer surface of side plate 102 to side plate 103) of sections 1 from the length of side plate 103 extensions.

Thus, a plurality of sections 1 that are fixed with bolt 9 connect in a circumferential direction, and are extremely shown in Figure 9 as Fig. 7.For this reason, at first, the left side is gone up the jut 105c of end plate 105 of sections 1 and auxiliary section 105d and is coupled among the figure on the right side on the groove 104c and auxiliary section 104d of the end plate 104 of sections 1 among Fig. 7, thus

Seal end plate

104 and 105 mutually.Then, as Fig. 8 and shown in Figure 9, by from the opening 101a inserting bolt 6 of the inner panel 101 of right side sections 1 and pass bolt hole 104a on

end plate

104 and 105 and 105a, from the opening 101a of left side sections 1 insert nut 7, be screwed to nut 7 on the bolt 6 and with nut screwing clamping to end plate 105, be coupled to each other sections 1 and 1.After the connection, the lid (not shown) that is used to block opening 101a is assembled to opening 101a and goes up and be fixed by for example contacting with the engaging mechanism (not shown).

Thus, a plurality of sections 1 connect in a circumferential direction continuously, are assembled into duct member 2 thus, as shown in figure 11.Further, it is so far away that the duct member of assembling 2 is sent to the reparation position that has pipeline 4 inside now continuously, and connect continuously in the vertical, manages 3 thereby assemble and lay to repair.

Figure 10 illustrates the situation that is coupled to each other duct member 2 by bolt 9.Be connected to for the duct member 2 with the left side on the duct member 2 on right side, at first, the bolt 9 that stretches out from the side plate 103 of the sections 1 of right side duct member 2 inserts the side plate 102 at bolt 9 loose positions of the sections 1 of left side duct members 2.Bolt 9 further inserts and passes the bolt hole 102a of gusset plate 106 and 107 and 106a and pass notch portion 107a, and keeper 19 enters among the bolt hole 102a simultaneously.Then, the side plate 102 of the sections 1 of left side duct member 2 is pressed against on the side plate 103 of sections 1 of right side duct member 2.In this case, auxiliary section 102c shown in Figure 6 is coupled on the 103c of auxiliary section, seals side plate 102 and 103 thus.The point of the bolt 9 that stretches out from right side duct member 2 sections 1 arrives near the inboard of side plate 103 of left side duct member 2 sections 1.Then, by being fastened on the gusset plate 106 adjacent with side plate 103 on the point that nut 10 is screwed to bolt 9 from bolt hole 103a and with nut, left side duct member 2 is fixed and is connected among the figure on the right side duct member 2.Thus, to shown in Figure 12, continuous in the vertical the connection will repair pipe 3 of duct member 2 is laid within the existing pipeline 4 as Figure 11.

The reparation pipe that lays 3 is made of plastic material, has low-gravity, thereby floats on the filler as previously mentioned.Therefore must press down and repair pipe 3, and regulate its position make it from existing pipeline 4 concentric position biased downward a little, thereby the bottom of the existing pipeline 4 of the following end in contact of its periphery.

Therefore, when repairing pipe 3 and be assembled into specific length (for example, approximately 1m), just by carrying out position adjustments, as shown in figure 13 in existing pipeline 4 inner wall surface and a plurality of positions insertion distance pieces 13 of repairing between the pipe 3 upside peripheries.

Distance piece 13 comprises that the upper surface side of first wedge 14 and second wedge, 15, the first wedge is shown among Figure 14, and the lower face side of second wedge is shown among Figure 15.Two

wedge

14 and 15 are configured to vertically overlapping, as Figure 17 and shown in Figure 180.In addition, if the insufficient height of distance piece, then it comprises overlapping lifting member 16 in its lower section, and as Figure 20 and shown in Figure 21, the upper surface side of this lifting member is shown among Figure 16.The direction of insertion of the arrow A indication distance piece among Figure 14 to Figure 16, Figure 19 and Figure 21, and distance piece 13 inserts on the direction A that repairs between pipe 3 peripheries and existing pipeline 4 inner wall surface.In addition, these

elements

14,15 and 16 form the goods of molded goods of plastics or metal-molding.

The monnolithic case of first wedge 14 shown in Figure 14 is essentially wedge shape and tilts with the mild predetermined angulars that for example are slightly smaller than 10 degree, thereby on the direction of insertion A of distance piece, upper surface is low and uprise in the distally at nearside.First wedge 14 has the guide groove 14a of a Rack in the centre, this guide groove is extended in the vertical, and on its basal surface, with short regulation pitch, as about several millimeters, is formed with a plurality of tooth 14b with zigzag along incline direction.The shape of cross section of each tooth 14b is a triangle; The leg-of-mutton limit that is formed on the wedge 14 direction of insertion distally is substantially perpendicular to direction of insertion, and the leg-of-mutton limit that is formed on the nearside is (with reference to Figure 17 and Figure 18) of tilting.

In addition, wedge 14 has two in the vertical along the linear elongated hole 14c that extends of guide groove 14a, and has two

leg

14d and 14e in the bottom, and recess 14f is formed on middle part (recess of leg 14e is not shown) simultaneously.

The monnolithic case of second wedge 15 is essentially the wedge shape identical with width with the length of first wedge 14, and the lower face side of second wedge is shown among Figure 15.Soffit with respect to wedge 15 vertically tilting with the upper surface angle same of first wedge 14 basically, and it is low and the distally becomes higher to be inclined on the direction of insertion of distance piece nearside.Yet wedge 15 illustrates in Figure 15 upside down, exposes soffit, thereby the orientation shown in Figure 15 is put upside down.

Wedge 15 has in the vertical the linear jut 15a that extends in the middle part, being formed with a plurality of tooth 15b than coarse pitch (as, about 10-20mm), described pitch is the integral multiple of pitch of the tooth 14b of first wedge 14 on this jut 15a.The shape of cross section of each tooth 15b is the triangle corresponding to each tooth 14b, but opposite orientation.The leg-of-mutton limit that is formed on the wedge 15 direction of insertion distally tilts with respect to direction of insertion, and the leg-of-mutton limit that is formed on nearside is vertical basically.And the width of jut 15a is slightly smaller than the width of the guide groove 14a of first wedge 14.In addition, the height of jut 15a (overhang) is corresponding to the degree of depth of guide groove 14a.

In addition, at the basal surface of wedge 15, there is the cylindrical projection of two weak points to divide on the both sides that 15c is respectively formed at jut 15a.Elongated

hole

15d and 15e are longitudinally in the preceding and back extension of this ledge 15c.In addition, wedge 15 is rounded at its point 15f.

The monnolithic case of lifting member 16 shown in Figure 16 is essentially rectangular frame shape, has length and the width identical with 15 with wedge 14, and its upper surface is with respect to vertically being level.And, vertically with respect to the broadwise symmetry, and arbitrary direction of insertion that vertically all can be used as distance piece.Wall 16g with specified altitude H3 (with reference to Figure 20) is formed on the both sides of lifting member 16 along the longitudinal.In addition, two big rectangular opening 16a are formed on the upper surface of the lifting member 16 of extending in the vertical, and a partition wall 16b is formed between the rectangular opening and has and the identical height H 3 of wall 16g on the both sides.In addition, on two ends of upper surface in the vertical, on the broadwise both sides, form step 16c, and jut 16d is formed between the two.In addition, form leg 16e respectively on the bottom at lifting member 16 both ends in the vertical, notch portion 16f is formed on the position, intermediate portion along broadwise.

If distance piece includes only first and

second wedge

14 and 15, the jut 15a of second wedge 15 is assembled among the guide groove 14a of first wedge 14 so, each ledge 15c inserts among each elongated hole 14c, and as Figure 17 and shown in Figure 180, the upper surface of the soffit of second wedge 15 and first wedge 14 is overlapping.Jut 15a is assembled in the groove 14a on it is vertical slidably.By this assembling, first and

second wedge

14 and 15 are alignd in the vertical, and their positions on broadwise also align, thereby prevent second wedge 15 slippage or whereabouts on broadwise.

If first wedge 14 and second wedge 15 are overlapped in this way, then tooth 15b respectively with a plurality of tooth 14b of first wedge 14 in any tooth engagement.But, if second wedge 15 pressurized on direction of insertion, shown in arrow A among Figure 18 b, then because tooth 14b and the intermeshing shape of 15b cause tooth 15b to stride across at tooth 14b.This just makes them throw off and second wedge 15 is moved towards first wedge 14 on direction of insertion.In addition, second wedge 15 moving on direction of insertion by guide groove 14a and jut 15a guiding.In addition, its range of movement is confined to from position that the ledge 15c of second wedge 15 contacts the end edge of first wedge, 14 elongated hole 14c on the nearside on the direction of insertion (hereinafter, be called extreme lower position) contact the position (hereinafter, being called the extreme higher position) of the end edge on the distally on the direction of insertion to it.

As mentioned above, wedge 15 is removable on direction of insertion; But, under the state of

tooth

14b and 15b engagement, since the shape of

tooth

14b and 15b causes tooth 15b to be stuck in and locking on tooth 14b, even pulling wedge 15 on the rightabout of direction of insertion, so wedge 15 can not move with respect to wedge 14 on the rightabout of direction of insertion.

Based on said structure, by on direction of insertion, pressing second wedge 15, this second wedge is moved with the pitch corresponding to the pitch of tooth 14b to the extreme higher position from extreme lower position continuously with respect to first wedge 14, and this second wedge 15 is latched in locked position of coupler, makes it on direction of insertion or rightabout, not move.Thus, be meshing with each other by the tooth that makes first and second wedge, can obtain a kind of blocking device, this blocking device can be realized different distance piece height at each locked position of coupler thus with the first and second wedge lockings in a plurality of locked position of couplers place.

Figure 18 a shows the extreme lower position of wedge 15, and Figure 18 b shows the state of extreme higher position.At the extreme lower position state,

wedge

14 and 15 overall height (comprising this overall height to the distance piece of wedge) are the minimum altitudes of being represented by symbol H1; In addition, wedge 15 moves many more on direction of insertion, and then wedge 15 is climbed highly more along the inclined upper surface of wedge 14, thereby overall height becomes high more; It arrives the maximum height of being represented by symbol H2 of extreme higher position.By moving second wedge 15 from extreme lower position to the extreme higher position with pitch corresponding to tooth 14b pitch, first and

second wedge

14 and 15 overall height can by with the low height pitch (as, less than the pitch of 1mm) be set to Desired Height from minimum altitude H1 steppingly to maximum height H2.

When the distance piece that has only

wedge

14 and 15 was used to regulate the position of repairing pipe 3, as shown in figure 19, wedge 14 is set for: its

leg

14d and 14e joined on two gusset plates 106 of sections 1.Then, second wedge 15 is inserted in the gap that has now between pipeline 4 inner wall surface and reparation pipe 3 peripheries,

wedge

14 and 15 is set on the periphery of repairing pipe 3 in extreme lower position.In addition, by on the direction of insertion shown in the arrow A, pushing second wedge 15, so that this wedge moves with respect to first wedge 14 on direction of insertion,

wedge

14 and 15 overall height are (promptly, the overall height of distance piece) become step-by-step movement to increase continuously with minimum pitch, as mentioned before, thereby by it is moved to highly become with the expectation gap the corresponding Desired Height of size (for example, shown in dotted line) the position, carry out position adjustments.

In addition, because the upside of the most advanced and sophisticated 15f of wedge 15 is a rounding, so most advanced and sophisticated 15f can not be stuck on the inner wall surface of existing pipeline 4, thereby wedge 15 can steadily move.In addition, the soffit of the upper surface of wedge 14 and wedge 15 tilts with equal angular, so the upper surface of wedge 15 is levels.This just makes distance piece stably contact the inner wall surface of existing pipeline 4 and stably places existing pipeline 4 inner wall surface and repair the gap of managing between 3 peripheries.In addition, the leg 14d of wedge 14 and the size relationship of 14e are set in advance and are made two gusset plates 106 to engage, and without any play.

Therefore, the position of repairing pipe 3 can be regulated by the distance piece that comprises

wedge

14 and 15; But, if attempt the overall height dimension H2 of the size in the above-mentioned gap set by distance piece greater than the highest position of

wedge

14 and 15, the size of part (insufficient portion) that then lack of foundation is as shown in figure 20 with a lifting member 16 or as shown in figure 21 a plurality of lifting members 16 are overlapped under the wedge 14.

At this moment, engage with step 16c and protuberance 16d on lifting member 16 both ends, wedge 14 is overlapped on the lifting member 16 by making leg 14d on wedge 14 both ends and 14e and notch portion 14f thereof respectively.Wedge 14 can be in landing on the lifting member 16 on vertical or the broadwise thus.

In addition, if overlapping a plurality of lifting member 16, then engage by step 16c on the both ends that will go up leg 16e on lifting member 16 both ends and notch portion 16f thereof and following lifting member 16 and protuberance 16d and overlapping, last lifting member 16 can be from descending landing on the lifting member 16.

In addition, the wall 16g on the both sides of last lifting member 16 contacts down wall 16g on the both sides of lifting member 16 and the upper surface of spaced walls 16b with the soffit of spaced walls 16b, and is supported on down on the lifting member 16.Thereby if overlapping a plurality of lifting member 16, then as shown in figure 21, for each overlapping lifting member 16, the overall height H 4 of distance piece just becomes and exceeds the height H 3 of a partition wall 16b and two side 16g, as shown in figure 20.

The overall height of distance piece can step-by-step movement increase continuously the expectation height, and repair pipe 3 the position can by will comprise overlapping

wedge

14 and 15 and the distance piece of lifting member 16 be set on the periphery of repairing pipe 3 and push wedge 15 and make it to move towards wedge 14 and regulate in direction of insertion, this situation with the previously described distance piece that only comprises

wedge

14 and 15 is identical.

When laying reparation pipe 3, a plurality of duct members 2 are roughly being carried out every one meter part by the position adjustments that the above-mentioned type distance piece carries out.When finishing the laying of repairing pipe 3 total lengths and position adjustments, vertical up and down and left and right horizontal ground is installed in and repairs pipe 3 inside with several meters interval roughly with the supporting arrangement (not shown), manages 3 and deforms so that repair when preventing to fill filler.Subsequently, as shown in figure 13, filler 12 is inserted existing pipeline 4 inner wall surface and is repaired in the clearance space between pipe 3 peripheries, and inserts in the space on sections 1 inner panel 101 outsides of repairing pipe 3.

Filler 12 comprises resin-bonded mastic, epoxy resin or the mylar that mainly is made of cement mortar, and similar item.The filling of filler is performed such, and promptly approximately just forms a hole 1a, connects to fill on this hole and pour into from this flexible pipe 11 with flexible pipe 11 and with filler 12 every repairing more than 3 meters length of pipe by the correct position place at upside sections 1.In addition, before filling, the gap of the reparation pipe 3 that assembles between periphery on the two ends of whole length and existing pipeline 4 inner wall surface uses the encapsulant that is made of similar item (not shown) such as resin putty or plaster to block.

And filler 12 also flows in

hole

14c, 15d, the similar items such as 15e, 16a of distance piece, therefore can not form cavity in distance piece.

Finish after the filling of filler 12, filler 12 solidifies and hardens, and after this blocks hole 1a with encapsulant, removes supporting arrangement (not shown) etc., finishes the repair of existing pipeline thus.

According to the foregoing description, position adjustments can be increased to Desired Height carries out by the overall height with distance piece, repairs the position of pipe 3 and can use the extremely very easy and adjusting at short notice of simple steps.In addition, do not need as conventional spacer, to make screwed hole, therefore do not need special steps, such as in downstream, blocking screwed hole for bolt.In addition, do not need as conventional spacer, to prepare the distance piece of multiple differing heights, and only prepare three class components and just can suitably carry out position adjustments different gap.

And, in the structure of the distance piece of the foregoing description, also acceptable is: vertically put upside down first and

second wedge

14 and 15, the leg 14d that removes first wedge 14 makes it to become second wedge, leg is connected on second wedge 15 makes it to become first wedge.

In addition, the surface in the face of existing pipeline of second wedge 15 be planar shaped and also do not tilt; Strictly speaking, when being inserted in existing pipeline and repair between the pipe in the gap, the inner peripheral surface of existing pipeline can not form the surface contact, therefore can also accept be make and existing pipeline facing surfaces crooked in a circumferential direction, and make curved surface have the curvature identical to contact so that further improvements is surperficial with the inner peripheral surface that has pipeline now.In addition, the tooth 14b pitch in an inclined direction of first wedge 14 is different from the tooth 15b pitch in an inclined direction of second wedge 15, but also can be made for identical pitch.

In addition, according to position adjustments distance piece of the present invention and utilize the position adjustments method of this position adjustments distance piece to be not limited in the repair of existing pipeline, repair the position adjustments of pipe, insert position adjustments in the gap between the object that fixed object and position remain to be regulated but certainly be widely used for distance piece.
