In the present embodiment, basic propulsion system 10 is promoted mainly the oil-feed cylinder by one group and is formed a connection anterior shield 2 and a pole 6.When normal mode tunneled, promoting mainly the oil-feed cylinder was that cutterhead 1 provides thrust.Promote mainly the oil-feed cylinder and be divided into 4 unit, each unit is equipped with stroke sensor, and the stroke situation shows in the control room.Each unit hydraulic fluid flow rate can and be monitored its position by the operator adjusting, adjusts the attitude of TBM when driving in view of the above.
In the present embodiment, said secondary propulsion system (SPS) 12 is formed by being arranged in a pole 6 one group of inner auxiliary propulsion oil cylinder.In the location that runs into landslide tomography and IV-V class surrounding rock, when the support boots can not be worked, the auxiliary propulsion cylinder acted on and can tunnel continuously on the steel pipe sheet fast through the relatively poor hole of geology section.The auxiliary propulsion oil cylinder is divided into four groups, and every group all is equipped with stroke sensor, and when off-order mode was tunneled, the oil pressure of each group can be controlled separately, makes operator can monitor its position is also adjusted development machine in view of the above when changing step attitude.
In the present embodiment, the curved plate that finger-type shield 7 its front portion structure forms are width 1m, afterbody is a long lath, finger-type shield 7 is provided with and covers 180 ° of zones, shield top, can make steel bow member erector 13, bores 8 in advance, operating personnel obtain better protection.
Like Fig. 1, shown in 5, in the present embodiment, girder 15 is a trussed construction, and steel bow member erector 13, anchor pole bore 14 and bore 8 in advance and be installed in its periphery, and the inner belt conveyor 19 that allows passes through.Girder 15 connects cantilever through bolt and is installed in pole 6 inside; In the 180 ° of inverted arch scopes in its top the finger-type shield 7 that operation is played the safeguard protection effect is housed, steel bow member erector 13, the anchor pole brill 14 that satisfies supporting requirement in the driving is set on the girder 15 and bores 8 in advance.It is two anchor pole drill systems that anchor pole bores 14, is positioned at steel bow member erector 13 back, is distributed in girder 15 left and right sides, can on the wall of the hole of 360 ° of scopes, hole, and also can move forward and backward the boring of 1.8m scope; Leading bore 8 on girder 15, be positioned at anchor pole and bore after 14, can control the boring in 360 ° of zones, but both horizontal drillings can be drilled tunnel wall along 6 ° pilot hole again, as the usefulness of surveying bad rock, cement-grouting consolidation country rock and probing drainage tunnel.Leading brill 8 can be implemented vault greater than leading probing of 150 ° of scopes and diversion tunnel probing.
Like Fig. 6, shown in 7, in the present embodiment, used steel bow member was installed when steel bow member erector 13 both can be to supporting, can be secondary propulsion system (SPS) 12 again the steel pipe sheets are installed, and satisfied the needs of improper driving.
As shown in Figure 4, it is inner that belt conveyor 19 runs through whole development machine main frame, and front end reaches the slag gathering hopper position of cutterhead 1, and the rear end extends to the post-matching leather belt machine.When slagging tap the rock slag by the scraper bowl on the cutterhead 1 shovel at the bottom of the hole into, be discharged on the inner conveyor of slag gathering hopper through chute again when scraper bowl rotates to top with cutterhead, conveyor running row unloads the rock slag.
In the present embodiment, general compact type hard rock mole has three kinds of typical driving patterns:
Brace type driving when stablizing country rock: the support boots stretching of a pole both sides is promoted mainly the oil-feed cylinder and is pushed to disc driving system and realizes driving to tunnel wall, uses anchor pole to creep into to go according to geological condition and design demand simultaneously and plays the anchor pole operation.Driving is ended, and stabilizer and supplemental support stretching tunnel wall be anterior shield fixedly, promotes mainly the drive of oil-feed cylinder and props up back genus equipment such as pole and advance and reset thereby regain.
Brace type driving during the instability country rock: the support boots stretching of a pole both sides is promoted mainly the oil-feed cylinder and is pushed to disc driving system realization driving to tunnel wall, meanwhile can be at the regional assembly unit steel pipe of finger-type shield sheet.Driving is ended, and stabilizer and supplemental support stretching tunnel wall be anterior shield fixedly, and the auxiliary propulsion oil cylinder supports on the steel pipe sheet promotion and props up back genus equipment such as pole and advance and reset
Single shield formula driving during soft rock: utilize the auxiliary propulsion oil cylinder to realize driving as single shield development machine, driving is ended at finger-type shield zone assembly unit steel pipe sheet.
Can find out by the foregoing description, the utlity model has following beneficial effect:
1, cutterhead adopts the design of panel type box-structure, has enough strength and stiffness, can play the effect of effective support face, stablizes face, avoids landslide.
2, complex optimum structural configuration has effectively shortened the shield body length, has reduced shield body and tunnel wall friction, avoids card machine accident to take place.
3, the shield body is designed to the pattern of stepped change, and machine body of boring machine is tapered, has effectively avoided the generation of card machine accident when running into shrinkage country rock or process fault belt.
4, high pulling torque, high thrust design make development machine have the stronger ability of getting rid of poverty.
5, articulated system cooperates compact shield body length, makes development machine can adapt to littler turning radius.
6, promote mainly into auxiliary propulsion two cover propulsion systems be equipped with steel bow member erectors, anchor pole bores and support apparatus such as leading rig, makes development machine have geology adaptive capacity more widely.
7, the design of finger-type shield makes its protection domain more wide, and security performance promotes greatly.
8, cantilever truss formula girder is not merely support apparatus and provides support, and the inner space satisfy conveyor pass through require.
9, steel bow member erector can be installed the steel bow member, and the steel pipe sheet of different in width can be installed again.Auxiliary cylinder can be supported on the steel pipe sheet when advancing, and makes that improper driving is more flexible, and cost is cheaper.
10, both kept the characteristics such as step-by-step system, supporting means of traditional open type TBM, the advantage and the operation that have taken into account the multiple driving pattern of two shield TBM again are more prone to easy.This makes general compact type TBM almost can be suitable for all geological conditions.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from the spirit and the scope of the utility model.Like this, belong within the scope of the utility model claim and equivalent technologies thereof if these of the utility model are revised with modification, then the utility model also is intended to comprise these changes and modification interior.
