The slurry balanced underground pipe jacking machine head combined type cutter head comprises a main cutter head, and the main cutter head is provided with drilling bits, a central cutter bit and slurry inlet and outlet holes; the main cutter head around the central cutter bit is uniformly provided with cutter head combination block mounting holes which are provided with cutter head combination blocks; every cutter head combination block is composed of a combination frame and a cutter head block, the cutter head block is provided with the corresponding slurry inlet and outlet holes and mounted on the front side surface of the combination frame through a bolt, the combination frame is mounted on the corresponding cutter head combination block mounting hole through the bolt, and the front side surface of the combination frame is adhered to the inner wall of the main cutter head. According to the slurry balanced underground pipe jacking machine head combined type cutter head, a worker can go outside the cutter head from a working chamber via the slurry chamber and the cutter head and meanwhile enter the slurry chamber front the outside of the cutter head via the cutter head to maintain and repair the cutter head conveniently and the like, so that time consumption, labor consumption and money consumption and interference to the ground can be avoided, and time saving, labor saving and cost saving can be obtained.

Description

Mud and water balance underground pipe-driving head tool head
Technical field
The utility model relates to a kind of mud and water balance underground pipe-driving pelta structure head tool head, is the driving system critical piece of the little Suporting structure of underground jacking.
Background technology
At present, fast development along with city, infrastructure constantly perfect, the various pipelines such as communication, electric power, water supply, draining, natural gas are more and more intensive in underground layout, adding superstructure stands in great numbers, traffic route is crowded, and trenchless technology can be avoided as far as possible on the interference of people's normal life and road traffic and impact, so the application of trenchless technology seems particularly applicable and important.
In municipal engineering, water supply, sewage conduct are because caliber is large, and pipe Contact requires strict, and the degree of depth gradient must not arbitrarily be adjusted, complex geologic conditions, directly push pipe difficulty is larger, even cannot implement, therefore, reference subway shield tunnel construction inspires, little shield machine is succeeded in developing, and by little shield machine driving preexisting hole, instant pipe fitting jacking is the new technology of municipal engineering.Though this technology is at the early-stage in municipal engineering, significant economic benefit and social benefit have been obtained.But some problems also occur in application thereupon, as run into old pipeline, the waste and old basis of building, boulder, pattern foundation pit supporting structure in jacking construction, leave over the underground not clear obstacles such as lower anchor pole and happen occasionally.Once run into the jacking again of this problem, have to shut down from ground open cut with cleaning obstacle, and then recover jacking, waste time and energy like this, and to ground people's normal life and traffic, bring very big impact shutting down excavation place.Shield machine is a difficult problem of construction to the removing of the inspection of cutterhead and obstacle always at present.
Summary of the invention
In order to overcome the little shield machine of existing municipal engineering, in tunneling process, run into the risk that must shut down excavation when the obstacles such as geological condition is not clear, boulder, the waste and old basis of building cannot tunnel; the utility model provides a kind of mud and water balance underground pipe-driving pelta structure head tool head; it can get rid of the most of obstacle in driving, avoids as far as possible the phenomenon of shutting down excavation to occur.
For achieving the above object, the technical scheme that the present invention takes is:
A kind of mud and water balance underground pipe-driving head tool head, comprise operator dish, on operator dish, be provided with brill tooth, center cutter head and mud and enter hole, on described center cutter head operator dish around, be evenly provided with cutterhead combination block installing hole, on cutterhead combination block installing hole, cutterhead combination block is installed, cutterhead combination block consists of combo box and cutterhead piece, cutterhead piece is arranged on combo box leading flank by bolt, combo box is arranged on cutterhead combination block installing hole by bolt, and combo box leading flank is attached on operator dish inside wall.
On described center cutter head operator dish around, be evenly provided with eight cutterhead combination block installing holes.
On described cutterhead piece, be provided with mud access hole.
Cutterhead piece of the present utility model is arranged on combo box leading flank by bolt, combo box is arranged on cutterhead combination block installing hole by bolt, at cutterhead, need to overhaul while running into not clear obstacle with jacking, personnel enter muddy water storehouse from working bin by muddy water storehouse door, cutterhead combination block can be dismantled from operator dish, personnel can enter cutterhead outside by cutterhead combination block installing hole from muddy water storehouse cutterhead is maintained, alloy bores tooth and welds, the operation such as inlay, personnel can remove the obstruction running in cutterhead outside, the cleaning works such as cutting, after removing barriers, can continue excavation operation.During preparation, in the time of need clearing up muddy water storehouse, personnel can be from cutterhead outside on the ground, cutterhead piece is unloaded from combo box, and personnel can enter in muddy water storehouse by combo box, the foreign material that the displacement of cleaning mud cannot be cleared up, check sealing in storehouse, the operations such as derusting rust-proofing.The utility model can be conveniently to cutterhead service work etc., time-consuming, the effort, expensive of the excavation of avoiding stopping work, and the interference that ground is caused, time saving and energy saving, save cost.

The specific embodiment
As shown in Fig. 1-Fig. 7, a kind of mud and water balance underground pipe-driving head tool head, comprise operator dish 11, on operator dish 11, be provided with and bore tooth 14, center cutter head 15 and mud enter hole 16, on described center cutter head 15 operator dish 11 around, be evenly provided with cutterhead combination block installing hole 12, the utility model preferably arranges eight cutterhead combination block installing holes, on cutterhead combination block installing hole 12, cutterhead combination block 10 is installed, cutterhead combination block 10 consists of combo box 8 and cutterhead piece 7, on cutterhead piece 7, be provided with mud access hole, cutterhead piece 7 is arranged on combo box 8 leading flanks by bolt 13, cutterhead piece can be along contact wheel profile 9 laminatings on combo box 8, the two is stacked, be joined with bolts and form cutterhead combination block 10, combo box 8 is arranged on cutterhead combination block installing hole 12 by bolt, can with bolt, combo box 8 be fixed on to operator by inner side, muddy water storehouse coils on 11 inside walls.
When the utility model is specifically used, on the muddy water storehouse demarcation strip 3 between working bin 1 and muddy water storehouse 2, there are two dismountable doors 4, door 4 passes through nut mechanical connection with muddy water storehouse demarcation strip 3, when muddy water storehouse need to be overhauled, close mud inlet opening 5, open mud drain hole 6 and drain in muddy water storehouse after mud, maintainer can enter muddy water storehouse 2 by door 4 by working bin 1.In drilling process, when running into the place ahead and have obstacle, maintainer can unclamp the bolt of fixed Combination frame 8 and operator dish 11 in muddy water storehouse, cutterhead combination block is unloaded from operator dish, maintainer just can enter cutterhead outside by cutterhead combination block installing hole 12, removing obstacles, also can overhaul cutterhead alloy Zuan Chihe center cutter head.If when maintainer needs muddy water storehouse to overhaul cleaning in cutterhead outside, cutterhead piece 7 can be unloaded from combo box 8, just can entering muddy water storehouse by combo box 8, maintainer works, very convenient.
