Technical field
The present invention relates to be used for bury the semi-shield digging mahcine that pipe, order lay the propelling method that forms underground pipeline underground by propelling.
Background technology
In the past, as utilizing propelling method to build the excavation pusher of underground pipeline, semi-shield digging mahcine was widely known by the people.
Utilizing this kind semi-shield digging mahcine in the past that underground pipeline is built arrives in the vertical shaft process, by making the cutter arrangement rotation that is configured in excavator main body the place ahead, utilization is arranged on the rear of the above-mentioned excavator main body of propulsion plant backup in the vertical shaft of setting out and is pressed in the ground, is linked in sequence on this excavator main body then, advances and bury pipe underground and lay and construct underground pipeline.
This semi-shield digging mahcine in the past is recovered from this arrival vertical shaft after arriving vertical shaft.
But, construct during the engineering of this arrival vertical shaft very longly, and need a lot of labours.So the problem that causes cost to rise is arranged.And, can not be provided with under the situation that arrives vertical shaft, take with regard to having to the excavator of costliness is embedded in the medium measure in ground, also have and can't avoid the such problem of cost rising.And, have and can't down body follow vertical shaft one side be reclaimed or body dropped into once again problem such the underground pipeline that has laid in the situation that runs into the foundation situation of excavating difficulty etc.
As other prior art, have the spy and open disclosed excavation pusher on the flat 11-210375 communique.Shown in Figure 15 (a) like that, the excavation of putting down in writing on this communique pusher 50, sheet surface layer 51,52 by the tubular before and after being configured in, be configured in the excavator main body 60 in these sheet surface layers 51,52 and constitute with rotating freely by the handle of a knife 53 that dividing plate dish 54 is installed in these excavator main body 60 front portions.On the inner face of above-mentioned each sheet surface layer 51,52, loading and unloading freely are installed with a plurality of rings 55,56,57.And above-mentioned development machine main body 60 except that handle of a knife 53 and dividing plate dish 54, can resolve into the part of the size that can pass through manhole (arrival vertical shaft) 70 taking-ups at least, and these development machine main body 60 loading and unloading are mounted freely on above-mentioned a plurality of ring 55,56,57.And the connection jack 58,58 of the sheet surface layer 51,52 before and after being used to connect is freely to be installed with across the ring 56 of sheet surface layer 51 rear ends that are installed in the place ahead and the form loading and unloading of ring 57 that are installed in sheet surface layer 52 front ends at rear.
The excavation in the past that constitutes like this is performed as follows with the recovery operation of pusher 50.Promptly shown in Figure 15 (a) like that, the excavation that will arrive manhole (arrival vertical shaft) 70 is fixed with the state of protrusion in this manhole (arrival vertical shaft) 70 with the leading section of pusher 50.Then, shown in Figure 15 (b) like that, when handle of a knife 53 fusing are become the size that can reclaim from this manhole (arrival vertical shaft) 70, decompose excavator main body 60.Then, in this manhole (arrival vertical shaft) 70, reclaim handle of a knife 53, gear-box 61, reductor 62, motor 63, discharge pipe 64,65, connection jack 58, metal cage 66 etc. in proper order.
Recording and narrating on this communique has, according to this pusher 50 of excavation in the past, owing to can before manhole (arrival vertical shaft) 70, not build to reclaim the major part of body is not reclaimed with the state that can re-use from this manhole (arrival vertical shaft) 70, reduce such advantage so have shortening and the cost that to realize the duration with vertical shaft.
But, even use on the pusher 50, need manhole (arrival vertical shaft) 70 these situations without any variation when reclaiming body in this excavation in the past, have the problem identical with above-mentioned prior art.And, when reclaiming body, the handle of a knife that must fuse as described above, decomposition body, on the other hand, owing to when using body once again, must assemble handle of a knife and housing construction spare, so troublesome poeration is arranged, the problem of inefficiency.
As other prior art in addition, what have that the applicant proposed opens disclosed small-bore pusher on the 2000-303779 communique the spy.This small-bore pusher 100 in the past, as shown in Figure 16, by having and burying the roughly the same external diameter of pipe 150 external diameter underground, be connected the urceolus 101 that this buries the front end of pipe 150 underground, be inserted in this urceolus 101 in the body 102b of rear portion and have the first conduit 102 of connection, separating mechanism 130 and front portion that rotation is mounted freely on this elder generation's conduit 102, have and enlarge the cutter head 105 dwindle mechanism 120 and constitute.Above-mentioned connection, separating mechanism 130 is disposing the combination member with engagement groove 132 133 in week in the rear portion that is fixed on above-mentioned urceolus 101, with the rear portion that is installed in above-mentioned rear portion body 102b, on radial direction, enlarge the propulsive force transmission member 130a that dwindles, 130b, by making these propulsive force transmission members 130a, the 130b enlarged, combine with the engagement groove 132 of above-mentioned combination member 133, above-mentioned urceolus 101 is connected with above-mentioned first conduit 102, by making these propulsive force transmission members 130a, the 130b diameter reduction, remove its combination, above-mentioned urceolus 101 and above-mentioned first conduit 102 just become free state.And, mechanism 120 is dwindled in above-mentioned expansion, when the slip case 122 that is free to slide on axially in the tunnel is entrenched on the shaft component 121 of the core that is fixed on cutter head 105, cutting disc 124 is connected on this slip case 122 by link component 123, by utilizing helical axis 125 that this slip case 122 is endwisely slipped to the tunnel, enlarge and dwindle this cutting disc 124.
Like this in the small-bore development machine 100 of Gou Chenging, dwindle external diameter that mechanism's 120 enlarged make cutter head 105 and the external diameter of burying pipe 150 underground roughly the same the time by above-mentioned expansion, by above-mentioned connection, separating mechanism 130 first conduit 102 is connected with urceolus 101, by apply propulsive force on this urceolus 101 propulsive force is delivered to first conduit 102, what be linked in sequence and bury pipe 150 underground, carry out the regulation radical at the rear of this urceolus 101 buries pipe 150 lay underground.On the other hand, after this laying task of burying pipe 150 underground finishes, perhaps interrupt burying underground pipe 150 laying task, retract under the situation of first conduit 102, dwindling external diameter that mechanism 120 dwindles cutter head 105 by above-mentioned expansion makes it when burying the internal diameter of pipe 150 underground, after removing being connected of first conduits 102 and urceolus 101 by above-mentioned connection, separating mechanism 130, on this elder generation's conduit 102, apply back edge, then should elder generation's conduit 102 just not with urceolus 101 and bury pipe 150 underground and interfere, be recycled to vertical shaft one side of setting out thereby pass these urceolus 101 and bury pipe 150 underground.On the other hand, the first conduit 102 that cutter head 105 is in the diameter reduction state passes burying underground in the pipe 150 of having laid and is inserted on the urceolus 101, when connecting these elder generation's conduits 102 and this urceolus 101 by above-mentioned connection, separating mechanism 130, dwindling mechanism 120 by above-mentioned expansion carries out after the hole enlargement of cutter head 105, on this elder generation's conduit 102, apply propulsive force, just can bury the laying task of pipe 150 once more underground.And, the adjustment in direction in the progradation, the waving of sweep 104 of anterior body 102a by being arranged on first conduit 102 and the coupling part of rear portion body 102b carried out.
According to this small-bore development machine 100 in the past, have can lay bury underground the pipe 150 after, make this elder generation's conduit 102 bury pipe 150 underground by this with the state that can reuse, easily be recycled to vertical shaft one side of setting out, and the first conduit 102 that temporarily is recovered to vertical shaft one side of setting out can be dropped into once again and bury underground in the pipe 150, at an easy rate the advantage of tunneling once again.
But the structure shown in opening this spy on the 2000-303779 communique is applicable to that intactly diameter group semi-shield digging mahcine big, that structure is also different is very difficult mutually with small-bore pusher.One of its reason is, in the structure shown in this spy opens on the 2000-303779 communique, protrude installation though have the first conduit 102 of sweep 104 from the front end of burying pipe 150 underground, but first conduit 102 main parts are different with the external diameter of burying pipe 150 underground, on outer peripheral portion from cutter head 105 to first conduit 102 main parts of burying pipe 150 underground, and produce the space between the ground, this space that under the little situation of excavated diameter, does not have what problem, along with diameter becomes big, can become the main cause that causes problems such as the subsidence of foundations.And though if sweep 104 is not set then body length can shorten, what can relax present described problem, just can not revise direction of propulsion in this case in the nature of things.And the first conduit 102 shown in this spy opens on the 2000-303779 communique is only applicable to some specific caliber, under the situation that produces the different engineering of caliber, the such problem of first conduit 102 of other size that necessary use matches with it arranged.
The invention of the present invention for carrying out in view of such problem, its purpose is to provide a kind of semi-shield digging mahcine, even without arriving vertical shaft, also can easily and with the state that can re-use body be recovered to vertical shaft one side of setting out by the pipe of burying underground that lays, and the body that temporarily is recovered to vertical shaft one side of setting out can be put into once again again and be buried underground in the pipe, easily tunnel once more, and have and go for the different versatilities of burying the pipe diameter underground, can carry out correctly, adjustment in direction smoothly.
