Technical field
The present invention relates to a kind of intergrated expansion inserted composite shield cutter head of tunneling shield development machine; relate in particular to the edge shell type composite shield cutter head that a kind of excavation cutter cutterhead that the excavation cutter is installed can sliding extension with respect to the rock stratum cutter cutterhead that hobboing cutter is installed; this kind shield cutter can improve efficiency of construction, reduce construction risk, also can play good effect to the protection cutter.
Background technology
Shield method is a kind of of tunnel excavation construction method, has been developed rapidly in Japan since the sixties, all is used widely in the subway work in a lot of cities, though it is historical not long, occupies critical role in the shield-tunneling construction technical field.China formally adopted shield method to build running tunnel in 1989, was used widely in the underground railway construction in cities such as Guangzhou, Shenzhen at present.Shield construction has that speed of application is fast, hole physique amount is more stable, to characteristics such as surrounding constructure influence are smaller, be the method that is adapted at the construction of soft foundation section.
The cutterhead of tunnel machine need dispose different cutters for different geo-logical terrains.The weak soil layer only needs common excavation cutter; The ground stratum need dispose hobboing cutter.For existing weak soil layer the compound stratum of rock-soil layer is arranged again, need to use compound cutterhead.Composite shield is called combination shield structure (also claiming general shield structure, mixed type shield structure) abroad again, and composite type is varied, and wherein the composite type of weak soil shield structure and rock shield structure is more common, and at present, the composite shield of China mostly is this kind.This kind shield structure has rock shield excavation machine and weak soil shield excavation machine function concurrently, can be in the compound stratum that rock and weak soil have concurrently jointly normal driving.
Composite shield cutter head is one of technological difficulties of composite shield.When in compound stratum, tunneling, on cutterhead, should arrange the excavation cutter that is suitable for excavating weak soil, arrange the hobboing cutter that is suitable for ground again.When in weak soil, advancing, worn and torn by sand for fear of hobboing cutter, or on hobboing cutter, adhere to clay, must reduce the hobboing cutter height, by the excavation cutter cutting soil body; And when in ground, advancing, the excavation cutter must be retreated again, release hobboing cutter, avoid excavating cutter and break.
Tradition composite shield cutter head both domestic and external, hobboing cutter and excavation cutter generally all are to be installed in simultaneously on the cutterhead panel, are a kind of vertical view of existing compound cutterhead shown in Fig. 1.A plurality of hobboing cutters 91 and excavation cutter 92 are installed above this cutterhead 9.Some of them hobboing cutter 91 and excavation cutter 92 are installed on the knife rest on the cutterhead, come reinforcement intensity by reinforcing girth sheets 93 between the knife rest.In the composite shield cutter head 9 of prior art shown in Figure 1, excavation cutter 92 is mainly used at the cutting of weak soil and hobboing cutter 91 is mainly used to the cutting at the ground stratum.
But this hobboing cutter 91 and excavation cutter 92 existing composite shield cutter head 9 in one plane are when compound stratum excavates, will run into a problem, be that hobboing cutter 91 and excavation cutter 92 are pushed ahead on same plane, hobboing cutter 91 tunnels easily wearing and tearing in weak soil, and excavation cutter 92 runs into ground consisting of hard rock and can break easily.
It is that every hobboing cutter can stretch separately that a kind of design is also arranged, or the ground independence is good, when shield structure turnover rock-soil layer, as required, is entered in the cutterhead soil cabin by the people and to change hobboing cutter.But preceding a kind of mode, the cutter head structure complexity, hobboing cutter changes difficulty, requires long in time limit; A kind of mode in back, limitation is big, the construction risk height.
Summary of the invention
Main purpose of the present invention is to provide a kind of intergrated expansion inserted composite shield cutter head, this cutterhead can only use common excavation cutter in the cutting soft soil layer, and can use hobboing cutter in the hard formation in cutting, in the weak soil layer, wear and tear and excavate cutter and run into phenomenons such as hard rock breaks easily thereby reduce the hobboing cutter that occurs easily under the isoplanar propelling situation in the prior art.
For solving the problems of the technologies described above, the invention provides a kind of integral telescopic composite shield cutter head, it includes a rock stratum cutter cutterhead and one can be along shield structure axis direction with respect to rock stratum cutter cutterhead weak soil excavation cutter cutter cutterhead in axial sliding under the drive of oil cylinder; On the cutter cutterhead of rock stratum a plurality of hobboing cutters are installed, on the excavation cutter cutterhead a plurality of excavation cuttves are installed; Wherein when carrying out the headwork of hard formation, excavation cutter cutterhead is inwardly withdrawn along the direction of shield structure axis, and when carrying out the headwork of weak soil layer, excavation cutter cutterhead is extrapolated to the both allocations that surpass fixed rock stratum cutter cutterhead along the direction of shield structure axis.
Use composite shield cutter head of the present invention, hobboing cutter is worn and torn by the weak soil layer easily and excavates the problem that cutter is broken by hard formation easily in the time of just can avoiding in the prior art hobboing cutter and excavation cutter isoplanar to advance effectively.
