Two end part at wainscot 101, be formed with and be used for a plurality of opening portion 101a of pipeline section 1 in the circumferencial direction connection, and for pipeline section 1 is connected in the pipe range direction, on side plate 102,103 and inner panel 106, be formed with a plurality of hole 102a of portion, 103a, 106a, on inner panel 107, be formed with a plurality of breach 107a.
As shown in Figure 2, from the opening portion 101a of pipeline section 1 bolt 6 is inserted to lead to and nut 7 is screwed togather behind inserting hole 104a, the 105a and, thus pipeline section 1 is connected at circumferencial direction two end plates 104,105 lockings.On end plate 104, be formed with recess 104b, 104c along whole pipe range direction, on end plate 105, be formed with protuberance 105b, the 105c chimeric with this recess along whole pipe range direction.Therefore, carry out easily during connection 1 operation of location of two pipeline sections to make it to be close to.By at the not shown sealing material of embedding part coating, can improve the water tightness of joint.When connection is finished, just wait airtight each opening portion 101a with cap (not shown).At this moment, the interior face of cap forms the inner face continuous homogeneous inner face with each wainscot 101.When carrying out being connected of circumferencial direction with bolt 6 with nut 7 easily, do not need to be provided with especially opening portion 101a.In addition, in Fig. 2, be to use two groups of bolts and nuts, but, also can only pipeline section be connected at circumferencial direction with one group of bolts and nuts pipeline section being used in both establishing when pipe of minor diameter.
The main structure that has shown pipeline section 1 in Fig. 3, promptly wainscot 101, side plate 102,103, end plate 104,105 in order to simplify accompanying drawing, have omitted reinforcing structures such as inner panel 106,107, flange.In this manual, so-called pipe range direction, be meant that pipe unit 10 among Fig. 3 extends along the length direction of pipe, with the direction shown in the arrow X, so-called footpath direction, be meant pipe unit 10 radial towards central shaft, with the direction shown in the arrow R, so-called circumferencial direction is meant the circumferencial direction of pipe unit 10.
Adopted when both having established the pipe restorative procedure, at first a plurality of pipeline sections 1 are connected and are assembled into pipe unit 10 at circumferencial direction both establishing in the pipe as described above, each pipeline section with pipe unit 10 connects in the pipe range direction again, is assembled into to repair pipe.
Fig. 4, Fig. 5 show shaft-like screw member (connector element) 11 that use two ends to be formed with screw section 11a, 11b is connected pipeline section with nut 12 in the pipe range direction state.The 102a of hole portion, the 103a that are shaped as side plate 102,103 that can be by pipeline section 1 of nut 12 and can not be by the 106a of hole portion of inner panel 106.And the size of the lip part 14a of the nut 14 that screws togather with the screw section 11a of screw member 11 can not be by the 106a of hole portion of inner panel 106 for the 102a of hole portion of side plate 102 that can be by pipeline section 1.The diameter of the lip part 13b of the bolt 13 that screws togather with nut 12 is bigger than the 106a of hole portion of inner panel 106, and the diameter of screw member 11 is littler than the diameter of the 106a of hole portion of inner panel 106.
Shown in Fig. 5 (a), make the hole portion 102a of nut 12, and make it be connected to inner panel 106 by the side plate 102 of a side pipeline section 1, bolt 13 is screwed in nut 12.Shown in Fig. 5 (b), nut 12 is anchored on the inner panel 106 is fixed on the pipeline section 1.Nut 12 can carry out pipeline section 1 as shown in Figure 3 in fixing also on the pipeline section 1 after circumferencial direction connects, or after at first nut 12 being fixed in pipeline section 1 pipeline section is connected and formation pipe unit 10 at circumferencial direction.
Shown in Fig. 5 (c), (d), make the hole portion 103a of nut 12 by the side plate 103 of the opposing party's pipeline section 1, and with two pipeline section 1 amalgamations.Under this state, shown in Fig. 4, Fig. 5 (e), make screw member 11 pass the 102a of hole portion, the 106a of hole portion of inner panel 106, the breach 107a of inner panel 107 of the side plate 102 of pipeline section 1, and screw section 11b is screwed in the nut 12 at pipeline section 1 place that is fixed on a side.Thus screw member 11 is connected with nut member 12.Then, shown in Fig. 5 (f), nut 14 is screwed in, be crimped on the inner panel 106 up to the lip part 14a of nut 14, two pipeline sections 1,1 are fastening.
In Fig. 4, be to utilize one group of bolts and nuts to carry out the connection of circumferencial direction, a bolt 6 shown in Figure 4.
By like that each pipeline section of pipe unit being connected in the pipe range direction as mentioned above, as shown in figure 18, can in both establishing pipe 9, assembling reparation manage 8.Filling material 8 ' such as mortar filling material in both establishing pipe 9 and the gap of repairing between the pipe 8 makes and both establishes pipe 9 and repair the integrated and formation composite pipe of pipe 8.
In Figure 18, the structure of each pipeline section 1 and being connected have been omitted for simplification in circumferencial direction and pipe range direction.In Figure 18, the joint 1a of the circumferencial direction of each pipeline section 1 be offset prearranging quatity at the joint 1a of the adjacent pipeline section of pipe range direction at circumferencial direction.The example of Fig. 4 is this side-play amount not, but as shown in figure 18, in the occasion of joint 1a skew, is to connect in the pipe range direction behind each adjacent pipeline section skew prearranging quatity.
Above pipeline section 1 is fixed at the width (Fig. 3 D) of pipe range direction.This means that pipeline section 1 can be called the fixed width pipeline section.And in Fig. 6, shown the pipeline section (hereinafter referred to as variable-width pipeline section) of pipeline section at the variable-width of pipe range direction.Fig. 6 (a)～(c) is with the sectional drawing of variable-width pipeline section when the footpath direction is cut off, and Fig. 6 (d) is the end view drawing that shows the end plate of variable-width pipeline section.
Variable-width pipeline section 2 is made of first and second pipeline section halfbody 3,4, and the braking rubber 5 as brake member is installed between pipeline section halfbody 3,4.
Be formed with recessed 301a, 301b in the both sides of wainscot 301, be formed with raised line 302a in the face of a side of pipeline section halfbody 4 at flange 302.On side plate 303, be formed with and connect with the hole 303a of portion.
Formed and the flange 302 of pipeline section halfbody 3 and the recess 407 of braking rubber 5 chimeric usefulness by inner panel 402,405 and wainscot 401.Shown in Fig. 7 (a), the size of each member is set for: between wainscot 401 and flange 302, form gap, between braking rubber 5 and inner panel 402, also form gap with minimum interval D 2 with minimum interval D 1.By such setting, shown in the arrow of Fig. 6 (a)～(b), need not apply load, the recess 407 that the flange 302 and the braking rubber 5 of pipeline section halfbody 3 can be inserted into pipeline section halfbody 4 swimmingly to each member.
Shown in Fig. 6 (c), carry out flange 302 and the inside that braking rubber 5 is inserted into recess 407 chimeric.Shown in Fig. 7 (b), brake the plane of inclination 402a of the preceding end in contact inner panel 402 of rubber 5 at this place.In advance low viscous binder 5 ' is coated on thinly on the plane of inclination 402a and tabular surface 402b of this inner panel 402, braking rubber 5 can be fixed on the inner panel 402 of pipeline section halfbody 4.On the other hand, because braking rubber 5 is maintained between the raised line 302a and inner panel 305 of flange 302, so short of too big strength effect, braking rubber 5 just can not relatively move with pipeline section halfbody 3, and pipeline section halfbody 3,4 just is combined as a whole via braking rubber 5 under the state shown in Fig. 6 (c).At this moment, recessed 301b of the raised line 401a of wainscot 401 and wainscot 301 is chimeric, and the wainscot 301 of pipeline section halfbody 3 becomes the face that flushes that does not have step with the face of the upside of wainscot 401 in Fig. 6 of pipeline section halfbody 4.
Variable-width pipeline section 2 shown in Fig. 6 (c), (d) has shape, the structure identical with fixed width pipeline section shown in Figure 11.The wainscot 301 of variable-width pipeline section 2 is corresponding with the wainscot 101 of fixed width pipeline section 1 with 401, constitutes the interior face that flushes when managing when being assembled into to repair.The side plate 303,403 of variable-width pipeline section is corresponding with the side plate 102,103 of fixed width pipeline section 1 in addition, the corresponding and intensity of reinforcement variable-width pipeline section 2 of inner panel 304,404 and inner panel 106.In addition, the projection 403a of the 303a of hole portion of side plate 303, side plate 403 is also corresponding with the quantity of the 102a of hole portion, 103a on the side plate 102,103 that is formed at pipeline section 1 and be provided with a plurality of.
Variable-width pipeline section 2 is in the width D of pipe range direction ' identical with fixed width pipeline section 1 in pipe range direction width D (Fig. 3), the circular shape of variable-width pipeline section 2 is identical with the circular shape of fixed width pipeline section 1, is 72 circular shapes of spending that will form behind circumference five five equilibriums.So, the side plate 303,403 of variable-width pipeline section 2 is consistent with side plate 102,103 shapes of fixed width pipeline section 1, and each plate 301,302,304,305,401,402,404,405 of variable-width pipeline section 2, braking rubber 5 etc. is circular-arc for 72 degree that will form behind circumference five five equilibriums also.But, braking rubber 5 is not the pipeline section shape yet, but does endless belt circlewise.
By the inner face of the recess 407 of variable-width pipeline section 2 and flange 302 in Fig. 6 on face be coated with the sealing material in advance, can improve water tightness.Binder 5 ' allows the braking rubber 5 that is fixed in inner panel 402 also can reach the function of sealing.
Variable-width pipeline section 2 is same in being connected of circumferencial direction with pipeline section 1 in the connection of circumferencial direction, carries out in the mode of Fig. 2.That is to say, each end plate 306,406 amalgamation of two variable-width pipeline sections 2 are fastening with two end plates with bolts and nuts with hole portion 306a, the 406a (Fig. 6 (d)) of bolt by forming at each end plate place, connect at circumferencial direction thus.So just the variable-width pipeline section is assembled into the pipe unit 20 (Figure 10) that is made of variable-width pipeline section 2 in the circumferencial direction connection in regular turn.
Fig. 8 and Fig. 9 show the state that fixed width pipeline section 1 is connected in the pipe range direction via variable-width pipeline section 2.In Fig. 8,1 of the fixed width pipeline section on variable-width pipeline section 2 and right side be connected following carrying out: public shape link 16 is fixed among the 103a of hole portion of side plate 103 of fixed width pipeline section 1, and make the hole portion 303a of this public affairs shape link 16 by the side plate 303 of variable-width pipeline section 2, with the side plate 303 that is fixed on variable-width pipeline section 2 on female shape link 17 to carry out buckle chimeric.1 of the fixed width pipeline section in variable-width pipeline section 2 and left side be connected following carrying out: the projection 403a of variable-width pipeline section 2 is pressed among the 102a of hole portion of side plate 102 of fixed width pipeline section 1.But, though diagram not also can fix as Fig. 4, nut 12 shown in Figure 5 the and screw member 11 that screws togather of utilization and this nut 12 and variable-width pipeline section 2 is connected with the fixed width pipeline section 1 in left side on variable-width pipeline section 2.
Just variable-width pipeline section 2 can be connected between the fixed width pipeline section 1,1 by this way.As Fig. 8～shown in Figure 10, with allow the pipe unit 20 that constitutes by variable-width pipeline section 2 be positioned at relative with the interface 9a that both established pipe 9 to the pipe unit 10 that constitutes by fixed width pipeline section 1 of part and allowing be positioned at the mode of other parts, pipeline section 1,2 is connected and is assembled into and repairs pipe 8 in the pipe range direction.But, as described in to the explanation of Figure 18, repairing after pipe 8 assemblings finish, be in the gap between the periphery of repairing pipe 8 and the interior week of both having established pipe 9 filling have flowability and can be as time passes and the filling materials 8 ' such as mortar that harden.Repair pipe 8 and with both to establish pipe 9 integrated, constitute the good composite pipe of reparation by allowing the filling material sclerosis of filling, making with intensity across filling material.
By will be configured in by the pipe unit 20 that variable-width pipeline section 2 constitutes like that as mentioned above with both established pipe 9 interface 9a relative to part, as described below, can make the performance boost of composite pipe.
Suppose that having very big tensile force to act on because of earthquake etc. from the outside under state shown in Figure 8 both establishes pipe 9, as shown in figure 11, the interface 9a that had both established pipe 9 can separate.This moment across not shown filling material and with both established on the pipe 9 incorporate variable-width pipeline sections 2, the tensile force effect that this pipeline section halfbody 3,4 is separated is also arranged.When this tensile force reaches predetermined value when above, as shown in figure 11, pipeline section halfbody 3,4 can separate, at this moment, the raised line 302a of flange 302 shown in Figure 12 (b), the braking rubber 5 and make braking rubber 5 resiliently deformables of can nipping with the degree of depth T2 of 1/3 degree of the thickness T 1 of braking rubber 5.The braking rubber 5 because the raised line 302a of flange 302 nips, just the separation to pipeline section halfbody 3,4 has applied braking force., if tensile force is bigger than this braking force, then pipeline section halfbody 3,4 can relatively move the distance corresponding with the fractional dose of interface 9a, allows the pipe range of pipe unit 20 extend.
Here, even pipeline section halfbody 3,4 moves towards the direction of relatively separating, the braking rubber 5 as long as the raised line 302a of flange 302 nips, just kept the continuity of repairing pipe 8, even separated so both established the interface 9a of pipe 9, the silt etc. that also can prevent aqueousization flow into from this part 9a to be repaired in the pipe 8, thereby the vibration strength of pipeline is promoted.
[embodiment 2]
Figure 13 and Figure 14 show that variable-width pipeline section 2 is configured in the crooked position of both establishing pipe assembles the embodiment who repairs pipe.
As shown in figure 13, cooperate the bending of both having established pipe, will be connected between the pipe unit 10 that constitutes by three fixed width pipeline sections 1, be assembled into crooked reparation pipe 8 by the pipe unit 20 that variable-width pipeline section 2 constitutes.
In Figure 13, pipe unit 10 is in the size of pipe range direction, just fixed width pipeline section 1 is D (Fig. 3) at the width of pipe range direction, and the variable-width pipeline section 2 shown in Fig. 6 (c) also is D (=D ') at the width of pipe range direction.Here, variable-width pipeline section 2 relatively is offset by making pipeline section halfbody 3,4, and the width D of pipe range direction is changed.For example, the pipeline section halfbody 3,4 of variable-width pipeline section 2 relatively is offset in the state lower edge pipe range direction from Figure 14 (b) to (a), so that the raised line 302a of flange 302 moves α along the pipe range direction, then in this Offset portion, variable-width pipeline section 2 is D+ α just at the width of pipe range direction, and wainscot 301 and 401 raised line 401a, recessed 301b constitute angle and amplified θ 1.
The side-play amount (α) of the pipeline section halfbody 3,4 of variable-width pipeline section 2 can be adjusted on each position of the circumferencial direction of pipeline section, so as shown in figure 13, the width of variable-width pipeline section 2 is varied to continuously: along the circumferencial direction of repairing pipe 8, side-play amount becomes increasing from a side direction opposition side (among Figure 13 from downside towards upside).That is to say, each variable-width pipeline section 2 is place of interior week minimum (side-play amount is 0 among Figure 14 (b)) at curved part at the width of pipe range direction, in the periphery of curved part (Figure 14 (a) observes the position that is making progress relatively from the footpath direction), be varied to maximum (side-play amount is α) continuously.The pipeline section width is changed continuously, and then 20 bend angle θ 1 of pipe unit can make and repair 8 bend angle θ 1 of pipe.
Even the bend angle θ 1 of a pipe unit 20 is very little,, also can allow the bend angle of reparation pipe 8 integral body very big by pipe unit 20 is connected at a plurality of positions.At the used variable-width pipeline section 2 of present embodiment, preferably use the length of circumferencial direction short, promptly use the pipeline section after the circumference that will repair pipe 8 gives five equilibrium (for example more than the eight equal parts).This is reasonably to increase above-mentioned side-play amount continuously for each the variable-width pipeline section 2 to pipe unit 20.
As mentioned above, even side-play amount is changed, since parallel respectively and become identical size at the end plate 306,406 of the adjacent variable-width pipeline section 2 of circumferencial direction, so also can utilize said method, just variable-width pipeline section 2 is connected at circumferencial direction by the fastening of bolts and nuts.The Placement of pipe range direction too, the connection each other of variable-width pipeline section is embedded in the side plate 303 of adjacency by the projection 403a with side plate 403 the 303a of hole portion carries out, and variable-width pipeline section 2 can carry out with mode shown in Figure 8 with being connected of fixed width pipeline section 1.
Though do not illustrate, in the present embodiment, will repair pipe 8 be assembled in both establish in the pipe after with the filling material filling in the gap between the interior week of both establishing pipe and the periphery of repairing pipe 8 and will both establish pipe and reparation pipe integrated for the mode of composite pipe identical with above-mentioned mode.
Adopt present embodiment, if the pipe unit 20 that will constitute by variable-width pipeline section 2 with must crooked part not be connected, and the width of the variable-width pipeline section 2 of pipe unit 20 is adjusted in a manner described, just can be assembled into the reparation pipe 8 of bending.Thereby, do not need pipeline section is processed especially in the working site, can carry out the assembling of crooked reparation pipe simply in the short time.
In addition, similarly to Example 1, variable-width pipeline section 2 is flexible at width direction, so even external force is arranged from external action because of earthquake etc., also can prevent to repair the partial rupture of pipe at variable-width pipeline section 2.
[embodiment 3]
Do not requiring that the reparation pipe has the occasion of vibration strength, as shown in figure 15, can omit by braking rubber 5.
In Figure 15, all parts identical with Fig. 6 all add identical symbol and omit its detailed description.The flange 302 ' of pipeline section halfbody 3 is equivalent to the flange 302 of Fig. 6, and it is longer to compare its footpath direction with Fig. 6 at the raised line 302a ' of its front end formation.The inner panel 402 ' of pipeline section halfbody 4 is equivalent to the inner panel 402 of Fig. 6, compares with Fig. 6, is not plane of inclination and become tabular surface 402a '.
The raised line 302a ' of flange 302 ' is to leave the length that surplus ground inserts the recess 407 of pipeline section halfbody 4 in the length of footpath direction, shown in Figure 15 (a) and (b), the flange 302 ' of pipeline section halfbody 3 is embedded in the recess 407 of pipeline section halfbody 4, and shown in Figure 15 (c), formed the variable-width pipeline section 2 ' of not braking rubber.
This variable-width pipeline section 2 ' is also same with variable-width pipeline section 2 shown in Figure 6, connect at circumferencial direction and pipe range direction, and the utilization method identical with Figure 13 is assembled into crooked reparation pipe.
The variable-width pipeline section is integrated and fixing in both establishing filling material (mortar etc.) between the pipe of pipe and reparation by filling, so as shown in figure 15, not necessarily will be with 3, the 4 chimeric combinations of pipeline section halfbody, and can be as shown in Figure 16 that the pipeline section halfbody is overlapping and constitute the variable-width pipeline section.
In Figure 16, pipeline section halfbody 50 by: be equivalent to the wainscot 301 of Figure 15 wainscot 501, be equivalent to flange 302 ' flange 502, be equivalent to side plate 303 side plate 503, be equivalent to the inner panel 504,505 of inner panel 304,305 and be equivalent to end plate 306 end plate 506 etc. constitute; Each board 501～506 uses the plastics material identical with pipeline section 1 and integrally formed.Flange 502 is provided with step with respect to wainscot 501 and extends abreast with wainscot 501, and 506 of side plates 503, inner panel 504,505, end plate vertically extend with respect to wainscot 501.
Be formed with raised line 501a, stepped part 501b in the both sides of wainscot 501, be formed with raised line 502a in the face of a side of pipeline section halfbody 60 at flange 502.On side plate 503, form porose 503a.
The pipeline section halfbody 50,60 of Gou Chenging is shown in Figure 16 (a) and (b) in this manner, slide in the recess 601b of pipeline section halfbody 60 by the raised line 502a that makes flange 502, make the flange 502 of pipeline section halfbody 50 and the wainscot 601 of pipeline section halfbody 60 be moved into overlap condition.In case pipeline section halfbody 50,60 relatively is moved into the state that raised line 502a that the front end of the wainscot 601 shown in Figure 16 (c) is connected to the plane of inclination 501b of wainscot 501 and flange 502 is connected to inner panel 605, the width that has just formed the pipe range direction is the variable-width pipeline section 40 of D '.At this moment, the wainscot 501 of pipeline section halfbody 50 becomes same plane with the wainscot 601 of pipeline section halfbody 60.
Variable-width pipeline section 40 also with variable-width pipeline section 2,2 ' same, can connect in circumferencial direction, pipe range direction, and can on each position of the circumferencial direction of pipeline section, adjust the width of its pipe range direction.The pipe unit 41 that therefore can utilize the method identical to assemble out to constitute by variable-width pipeline section 40 with Figure 13, and the width of variable-width pipeline section 40 is increased continuously from a side direction opposition side along the circumferencial direction of repairing pipe 8.Like this, as shown in figure 17, can make the width D of variable-width pipeline section 40 be changed to D+ α continuously, can make and repair pipe 8 with angle θ 1 bending.
But, because pipeline section halfbody 50,60 is just overlapping simply, so footpath, possibility edge direction moves and separates.Therefore be preferably in the position of pipeline section width direction adjusted after, under the state that pipeline section halfbody 50,60 is overlapping, carry out interim bonding or fixing.In case both established pipe with repair pipe utilize filling in the filling material between them and integrated, pipeline section halfbody 50,60 just can not move, so can not move towards the footpath direction again.
Variable-width pipeline section 40 also can reach the effect same with variable-width pipeline section 2 ', with variable-width pipeline section 2 ' relatively, can obtain and the structure of pipeline section can be simplified such advantage.
