Description
Technical field
The present invention relates to cutter head of shield-driven machine type selecting and cutter configuring technical field, particularly relate to a kind of soft or hard inequality and invade mutually compound rock stratum shield cutter type selecting and cutter configuring technical.
Background technology
Diabase intensity is high, quartz is large with metalliferous mineral content, and the saturated uniaxial compressive strength of middle weathering diabase is up to 140MPa, by " Standard for classification of engineering rock masses " (GB50218-94), in the time of uniaxial saturated compressive strength of rock > 60MPa, belong to hard rock; By " code for geotechnical engineering investigation of subway and light rail transit " (GB50307-1999) and " Design of Railway Tunnel specification " (TB10003-2005) diabase belong to utmost point hard rock, the diabase that rate of decay is weak, by actual uniaxial compressive strength, its Polodyakonov coefficient coefficient f > 16, belong to general hard stone XIII class, belong to the extremely difficult layer that picks up that bores.Between different rate of decay diabases and diabase and slate Different Strata, present irregular, inhomogeneous, unsettled mutual intrusion and distribute, form soft or hard inequality and invade mutually compound rock stratum.
In, strong, completely decomposed slate, saturated uniaxial compressive strength is less than 30MPa, belongs to soft rock.
The diabase of different rate of decay, diabase and slate, present irregular, inhomogeneous, unsettled mutual intrusion and distribute between the slate stratum of different rate of decay, form soft or hard inequality and invade mutually compound rock stratum.Complex between Different Strata or different rate of decay rock stratum, mutual intrusion, face stratum proterties changes fast, lithologic character difference is large, stratum and weathering boundary conversion are frequent, compound stratum proterties is extremely obvious, and be mingled with lamelliform weathered sandwich, be rich in quartz and metalliferous mineral, stratum crushing, globality is poor, rock fracture is grown, easily become blocky joint, face utmost point out-of-flatness after knife cutting, shield driving difficulty, open a position and look into cutter, tool changing is frequent, security risk is large, cutter inordinate wear is serious, cutter has high input, efficiency of construction is low, construction cost and security risk increase.
Invade mutually the irregular driving scar in compound rock stratum in soft or hard inequality, the hobboing cutter cutting rule of cutter head of shield machine itself changes, hobboing cutter can not press scar to be clamp-oned and rotates, but constantly move fluctuatedly, therefore sustainable existence hobboing cutter lacks and puts forth effort interface and do not turn eccentric wear, impacted suddenly by rock and make the problem of cutter ring, cutter shaft fracture.Rock strength is high, wherein more contains a large amount of same high-strength quartzites and metalliferous mineral and cutter stress performance is required high, and tool abrasion obviously strengthens, and the life-span reduces rapidly, and tool rest girff has also been caused greater impact and caused distortion.
Invade mutually compound rock stratum in soft or hard inequality, because of face distribution of strata inequality, fragmentation, after cutting, rock is block cracked, the out-of-flatness of the face utmost point, it is stressed that the serrated knife of cutter head of shield machine and perching knife participate in brokenly rock in advance, under cutter head of shield machine rotates, is subject to the impact of the outstanding sillar of face, sharp rock, serrated knife and perching knife set bolt curvedly draw and are subject to that shearing is excessive to break because being subject to, cause cutter avalanche, the distortion of tool rest bolt hole, thread damage.The residual body such as hobboing cutter cutter ring, cutter hub of serrated knife, perching knife cutter and the fracture of avalanche repeatedly stirs in Ji Tu storehouse, cutterhead front, can not discharge in time, hobboing cutter is caused to very large shock, extruding, rubbing action, hobboing cutter large area is frequently occurred: be squeezed into girff, cause hobboing cutter generation eccentric wear; Cutter ring is squeezed de-, ineffective; Cutter ring is knocked and causes fracture or occur breach; Cutter shaft is stressed to rupture extremely; With cutter hub, extruding etc. occurs, cause cutter hub distortion, end cap is extruded, and cutter hub is by serious crimp, and girff distortion, finally cannot split out, and can only remove by destructive gas cutting, and cutter is scrapped.Hobboing cutter is stuck, the serious eccentric wear of cutter circle, and What is more, and after cutter ring fracture, cutter hub is serious by eccentric wear; Hobboing cutter is fixed voussoir, bolt and is out of shape, fractures because of a capacity.It is larger to the sealing infringement of hobboing cutter that soft or hard inequality is invaded compound rock stratum mutually, and under long-term High Pressure, seals damaged lost efficacy, and water and landwaste, powder particle etc. enter, and then make bearing rust, wearing and tearing.Wear-resisting and the body of cutterhead front edge (perching knife tool rest rear) is because perching knife avalanche loses protection, and drop cutter and tool rest fall into cutterhead bottom and stir and cause wearing and tearing with cutterhead.
Therefore wishing a kind of soft or hard inequality invades mutually compound rock stratum shield cutter type selecting and cutter configuring technical and overcomes or at least alleviate above-mentioned defect.
