In addition, sub-shield digger 12 with state that female shield digger 11 combines under, as depicted in figs. 1 and 2, has diameter than little circular in female shield structure next door 21 and be arranged to roughly become conplane shield structure next door 41 with female shield structure next door 21, and be provided with movable seal closure portion 42, this movable seal closure portion 42 is under the state of the inside that is accommodated in female shield structure next door 21 and sub-shield structure next door 41, along the periphery setting in sub-shield structure next door 41.This movable seal closure portion 42 is being fixed with receiving state by cover retainer 42a, by pulling down cover retainer 42a, just can slide towards tunneling direction the place ahead from sub-shield structure next door 41.In addition, sub-shield digger 12 with state that female shield digger 11 combines under, the sub-shield machine body portion 40 of Fig. 7 shown in waiting is not installed.
Tunneling direction the place ahead in sub-shield structure next door 41, sub-cutter tip 43 as the 2nd cutter tip of circular, look from the front and to be arranged on the position that roughly overlaps with the arcuation recess 23a of female cutter tip 23, and, be arranged on than female cutter tip 23 and more be partial on the position at tunneling direction rear.
This sub-cutter tip 43 has the cutter hub 43d that links with sub-crank mechanism 45, with the rotor 43a that backbreaks that can contact with this cutter hub 43d by jack 43e and sliding part 43f, link with breaking away from.This backbreak rotor 43a Fig. 1 middle and upper part be provided with 1 place, about be provided with 2 places.And, on these cutter hubs 43d or the rotor 43a that backbreaks, be fixed with a plurality of excavation rock mass cut drill 43b,, can carry out the parallel rod motion by being fixed on the sub-drive division 44 on the sub-shield structure next door 41 and having the crank mechanism 45 of a plurality of eccentric eccentric multi-shaft.
And, the 2nd son that excavates scope that can excavate by the parallel rod motion as this sub-cut drill 43 excavates scope 46, look from the front and to overlap with recess 23a, and its part is excavated scope 26 with the mother of female cutter tip 23 and is overlapped, and becomes the circular with sub-shield machine body portion 40 basically identicals.In addition, on sub-cutter tip 43, the side-prominent enlarged portion 43c of two leading section 32a that is provided with at female cutter tip 23 is so excavate the position that the enlarged portion 43c of scope 46 excavates, the position side that the leading section 32a that reaches at the female cutter tip 23 that is excavated scope 26 by mother excavates by son.
In addition, bottom in sub-shield structure next door 41, although sub-shield structure door portion 48 is arranged to and can links with sub-screw conveyer 59 shown in Figure 7, at sub-shield digger 12 with before female shield digger 11 separates, do not link, and become the state of sealing with sub-screw conveyer 59.
Under so female shield digger 11 and state as depicted in figs. 1 and 2 that sub-shield digger 12 combines, can excavate big section excavated hole by female cutter tip 23 and sub-cutter tip 43.Under this bonding state, the internal face in the big section excavated hole at the tunneling direction rear of female shield machine body portion 20 is provided with the female shield structure fitting machine 52 that is used to dispose the fan-shaped lining segment 51 of female shield structure, along with driving, can dispose the fan-shaped lining segment 51 of female shield structure successively.In addition, female shield structure jack 54 is being fixed, by pushing the reaction force of the fan-shaped lining segment 51 of female shield structure in tunneling direction rear in female shield machine body portion 20, make all of mother and sons' Shield digging device 10 of comprising female shield digger 11 and sub-shield digger 12, move towards tunneling direction the place ahead.
When excavating the excavated hole of big section by mother and sons' shield digger 10 of structure like this, at first, as depicted in figs. 1 and 2, under the state that has linked female shield digger 11 and sub-shield digger 12, push to tunneling direction by female shield structure jack 54, simultaneously, make female cutter tip 23 carry out the parallel rod motion by female drive division 24 and female crank mechanism 25, in addition, by sub-drive division 44 and sub-crank mechanism 45, sub-cutter tip 43 is independent of female cutter tip 23 drives, make it carry out the parallel rod motion.
At this moment, a pair of rotor 32 of backbreaking of female cutter tip 23 become and cutter hub 31 immediate states, and recess 23a becomes the state that shrinks most by jack 33 and sliding part 34.At this, by female cutter tip 23, excavate the scope of female excavation scope 26, but mother that should mother's cutter tip 23 excavates on the scope 26 and forms and the corresponding part of not excavating of recess 23a.Therefore, excavate this by sub-cutter tip 43 and do not excavate part.
At this moment, the mother of female cutter tip 23 excavates scope 26 and excavates scope 46 a part of coincidences with the son of sub-cutter tip 43, can not produce the gap in two excavation scopes 26,46.In addition, although excavate the position intersection that the leading section 32a of the rotor 32 of backbreaking of position that the enlarged portion 43c of the periphery of scope 46 forms and the periphery that is excavated scope 26 by mother forms by son, but what form on this cross section is concavo-convex little, becomes the continuous shape of the essentially no point of inflexion.Therefore, the internal face of big section excavated hole forms the section configuration of the circle of regulation.
In addition, in the present embodiment, on sub-shield digger 12, also be provided with the rotor 43a that backbreaks, if under the state of this rotor 43a that backbreaks is opened in expansion, excavate, but the excavated diameter section bigger then than common state.Thus, can strengthen the internal diameter of female cutter tip 23, so female shield digger 11 is separated with sub-shield digger 12, and makes under the situation of this sub-shield digger 12 by the inboard of female cutter tip 23, can prevent more reliably that 12 pairs of female cutter tips 23 of sub-shield digger from producing interference.
Then,, be converted to the excavation operation of light section excavated hole, excavate the light section excavated hole by the excavation operation of big section excavated hole in the moment that big section excavated hole is excavated assigned position.
When conversion, at first stop the excavation that mother and sons' shield digger 10 carries out, as shown in Figure 1, female cutter tip 23 is arranged at locating bottom of parallel rod motion.At this moment, preferably sub-cutter tip 43 is arranged on the position, the top of parallel rod motion.
Under this state, as shown in Figure 3,, the rotor 32 of backbreaking is moved on cutter hub 31 position farthest by jack 33 and sliding part 34, expand and open recess 23a.Thus, the medial margin of recess 23a is opened by expansion, greater than the section configuration of light section excavated hole.
Then, as shown in Figure 4, with the sub-shield digger 12 corresponding positions of female shield machine body portion 20 from sub-shield machine body portion 40 toward the tunneling direction rears, fixedly accept reaction force carriage 62.And, seal female shield structure door portion 28, will be installed in the female screw conveyer 29 on female shield structure next door 21, female shield structure fitting machine 52, female shield structure jack 54 etc., unwanted parts are removed when driving light section excavated hole.
In addition, pull down cover retainer 42a, make movable seal closure portion 42 from the slip around in sub-shield structure next door 41 to tunneling direction the place ahead, the part of sub-shield machine body portion 40 is installed.And, seal 58 is installed to prevent the mode that water enters in the machine around the sub-shield machine body portion 40.
Under this state, will be used to make sub-shield digger 12 to pull down with the fastening devices 65 that female shield digger 11 combines, just sub-shield digger 12 and female shield digger 11 can be broken away from.
Then, when pushing, make sub-cutter tip 43 carry out the parallel rod motion by sub-drive division 44 and sub-crank mechanism 45, so that sub-shield digger 12 moves temporarily by interim shield structure jack 64.
Then, as shown in Figure 5, between the 12a of pushing portion of interim shield structure jack 64 and sub-shield digger 12, add falsework 66 successively, simultaneously, proceed driving at leisure by sub-cutter tip 43.
At this moment, be disposed at the sub-cutter tip 43 on the tunneling direction rear of female cutter tip 23, along with driving, the recess 23a's by female cutter tip 23 is roughly inboard, moves towards tunneling direction the place ahead of female cutter tip 23.At this moment, the rotor 32 of backbreaking of female cutter tip 23 expands the bigger scope of opening than regulation of light section excavated hole, thereby, even sub-cutter tip 43 passes through the recess 23a of female cutter tip 23 in the parallel rod motion, can not contact with it yet.
Then, as shown in Figure 6, in the stage of having carried out the ormal weight driving by sub-shield digger 12, the remainder of sub-shield machine body portion 40 is installed, pull down interim shield structure jack 64, accept reaction force carriage 62 and falsework 66, sub-shield structure jack 69 is fixed in the sub-shield machine body portion 40.In addition, sub-shield structure erector 72 is installed, the fan-shaped lining segment 71 of sub-shield structure is set in turn on the internal face of the light section excavated hole of excavating by sub-cutter tip 43.
In addition, in the gap between female shield digger 11 and the fan-shaped lining segment 71 of sub-shield structure, injection can prevent reliably that sealing enters and be used for connecting more firmly both injection materials, and is solidified.
Afterwards, by continuing driving, excavate the light section excavated hole with sub-shield digger 12.
As above-mentioned, according to mother and sons' shield digger 10 that can excavate big section excavated hole and light section excavated hole, female shield digger 11 has the female cutter tip 23 that carries out the parallel rod motion with eccentric a plurality of axles, and, sub-shield digger 12 has the sub-cutter tip 43 that is provided with on the position of staggering with female cutter tip 23 on the tunneling direction, can distinguish and drive female cutter tip 23 and sub-cutter tip 43 independently, make it to carry out the parallel rod motion.Therefore, two cutter tip 23,43 synchronization actions needn't be made, female shield digger 11 and sub-shield digger 12 can be constituted simply.Simultaneously, be converted in excavation operation when the excavation operation of light section excavated hole from big section excavated hole, female shield digger 11 and 12 need of sub-shield digger are pulled down the shirtsleeve operation of link 65 etc., just can remove the bonding state of female shield digger 11 and sub-shield digger 12 simply, sub-shield digger 12 separates with female shield digger 11 easily, easily improves operating efficiency.
And because the excavation scope 46 of the excavation scope 26 of female cutter tip 23 and sub-cutter tip 43, looking in the front is the structure that a part overlaps, and therefore, excavates between scope 26 and the sub-excavation scope 46 mother and can not produce the gap.In addition, female excavation scope 26 and sub-excavation scope 46 part superpositions, therefore, the periphery of female excavation scope 26 can intersect with the periphery of sub-excavation scope 46, compares with the occasion that two excavation scopes 26,46 are close, can make be formed at concavo-convex on this part can be little.And, as adjust this coincidence status, also can adjust the angle of the periphery intersection of two excavation scopes 26,46 sleekly.Therefore, the periphery that can be suppressed at the periphery of female excavation scope 26 and sub-excavation scope 46 intersect produce on the internal face of big section excavated hole of part concavo-convex.
In addition, female cutter tip 23 is looked in the front and is had recess 23a, and the mode that coincides with this recess 23a and sub-excavation scope 46 has disposed sub-cutter tip 43, thereby peripheral part in the big section excavated hole that forms by female cutter tip 23, form the light section excavated hole easily, and by female cutter tip 23 and sub-cutter tip 43, can suppress concavo-convex generation, can form the big section excavated hole of smooth circular cross section.
In addition, the rotor 32 of backbreaking as the sidepiece of the recess 23a of female cutter tip 23, recess 23a displacement can be split into greater than the light section excavated hole with expansion, thereby be converted in excavation operation when the excavation operation of light section excavated hole, easily the parts of the sub-cutter tip 43 of the driving by being used for the light section excavated hole or the fan-shaped lining segment 71 of sub-shield structure etc. forwards from the tunneling direction rear of female cutter tip 23 from big section excavated hole.Therefore, can make the intersection of the female relatively excavation scope 26 of sub-excavation scope 46 more, the periphery that makes female excavation scope 26 and the edge part of sub-excavation scope 46 can be with little concavo-convex the intersections, can further suppress to produce on the internal face of big section excavated hole concavo-convex.
In addition, sub-cutter tip 43 carries out the parallel rod motion by a plurality of axles of off-centre, therefore, can make the size of sub-cutter tip 43 phase antithetical phrases excavation scope 46 little, can make sub-cutter tip 43 pass through recess 23a to the place ahead easily from the tunneling direction rear of female cutter tip 23.
At this moment, with female cutter tip 23 similarly, assembling when backbreaking rotor on sub-cutter tip 43 is as the contraction rotor of backbreaking, just can further dwindle the size of sub-cutter tip 43, sub-cutter tip 43 can pass through to the place ahead in easier tunneling direction rear from female cutter tip 23.
In addition, in the above-described embodiment, the section configuration that big section excavated hole has been described is circular situation, but the shape that big section excavated hole and light section excavated hole are looked in the front can be carried out suitable selection, can be by using the cutter tip of different shape, acquisition can suitably be chosen as shapes such as rectangle or ellipse by the shape due to the parallel rod motion of this cutter tip.
For example, as Fig. 8 and shown in Figure 9, big section excavated hole and light section excavated hole are looked from the front can become the outstanding laterally shape of a circular part, by making it become shape like this, can recess 75 be set in the part of the internal face of big section excavated hole and light section excavated hole, at this recess 75 and have the fan-shaped lining segment 51 of female shield structure of certain curvature and the part between the fan-shaped lining segment 71 of sub-shield structure forms space 76, fill in into material by injecting the back of the body, also can connect the structure of the fan-shaped lining segment 51,71 of each shield structure more firmly to this part.
