Description
Technical field
The utility model relates to constructing tunnel equipment technical field, particularly relate to a kind of engagement type multi-cutter-disk excavating device and
Development machine including the device.
Background technique
In current constructing tunnel, shield technique is fast, dirty with its high degree of automation, construction safety degree height, construction speed
The advantages such as small, at low cost are contaminated, are gradually used widely.Wherein, shield machine be it is a kind of using the collection machinery of shield method, electronics,
The technologies such as hydraulic, laser and control are in the high mechanization of one and the driving lining cutting complete set of equipments of automation.
The mountain tunnels such as domestic road and rail are often u-shaped cross-section, tunnel excavation usually using full section drill burst method,
The tradition engineering method such as benching tunnelling method, CD method, CRD method, two side-wall pilot tunnel, to realize that personnel are safer, execution conditions are more environmentally friendly, the duration
Shorter, demands such as cost control is less expensive, domestic and international professional technician to horse-shoe tunnel using shield construction into
It has gone numerous studies, has realized that the mechanical type excavated is varied, such as: " a kind of slurry-water balance type shape of a hoof shield machine " utilizes
The knife cutting that one big circular beater plate and special-shaped cutterhead (eccentric swing) form goes out horse-shoe tunnel, utilizes mud and water balance mode
It keeps excavating face stability；" a kind of large section shape of a hoof shield machine " utilizes earth pressure balance principle, is distributed using several front and backs
Circular beater plate excavated, the section of jurisdiction finished using newest ring assembly carries out the propulsion of complete machine as brace foundation, and the type is
Possess successful application case covering Sinorael, Baicheng tunnel, road；" it is a kind of for horse-shoe tunnel can cast-in-place supporting shield
Machine " it is tunneled using earth pressure balance principle, using basic as stretching apart from the section of jurisdiction that the far assembly of host finishes, by friction
The counter-force of offer, and by the propulsion of lever+flexural pivot power transmission progress complete machine, it excavates using three dise knifes in the same plane
Disk and three eccentric circular cutting disks are composed；" special section tunnel shield excavation machine " (Hitachi Zosen Corporation) passes through
Using digging control device and according to the advance and retreat amount of the corner of cutterhead and profiling cutter, the advance and retreat amount of each cutterhead spoke is controlled,
Minor axis part is excavated with cutterhead spoke when profiling cutter retreats, and excavates major diameter part when profiling cutter is prominent, can be easy
Excavation special section tunnel；" a kind of cutter head and its synchronisation control means of rectangular shield " (Shanghai tunnel), by setting
Angle setting is different with the first cutterhead of preceding piece housing and the second cutterhead, the eccentric multi-shaft positioned at the first cutterhead and the second cutterhead rear
Shape cutterhead, the first cutter plate driver for driving the first cutterhead to circle, for driving the second cutterhead to circle
Second cutter plate driver, the eccentric multi-shaft abnormity cutter plate driver for driving the eccentric rotary motion of eccentric multi-shaft abnormity cutterhead work, the
One cutterhead and the second cutterhead are X-shaped spoke type structure cutterhead, and set angle difference is 80-100 degree, the first cutterhead and the second cutterhead
Center away from less than the sum of the first cutterhead and the radius of the second cutterhead.First cutterhead and the second cutterhead do not collide mutually and
First working face is excavated, and eccentric multi-shaft abnormity cutterhead is cut in the second working face memory, and entire cutter head is disconnected in rectangle
Maximum area is cut in face, makes entire excavation face in rectangle, reaches cutting etc. comprehensively.
It is to sum up known, it is varied for the technology of special-shaped tunnel excavation both at home and abroad, with their own characteristics.There is currently big for the country
The mountain tunnel project of V grades of soft rock Soft Clays, and mostly two-wire high-speed rail project are measured, horse-shoe tunnel section is very big, in the world
It is also rare in constructing tunnel case, it is contemplated that entire construction cost and safety, first choice are dug using earth pressure balance mode shield
Into.Cost of equipment cost is huge, is cut the higher demand of soil body flow brought by u-shaped cross-section ultra-wide in order to solve,
Need that a kind of construction reliability is very high, cost relative moderate, sediment improvement preferably excavates system schema.
