The operation principle of the present invention：As depicted in figs. 1 and 2, supporting shield body is made up of backplate and internal support, and backplate includes
Backplate 10 and bottom guard plate 4 after sidepiece apron plate 1, sidepiece, backplate 10 is hinged 6 companies by backplate after sidepiece apron plate 1 and sidepiece
It is connected together, forms the entirety of front and rear insertion；Inside support includes front support 2 and back support 7, inside support outside and shield
Plate contact site sets neck, and backplate is arranged in neck, forms stable supporting shield body with internal support, the section of backplate is in
U-shaped, the supporting shield body support sidepiece soil body, safe working space is internally formed in shield body；
As shown in Figure 3 and Figure 4, backplate 10 and bottom guard plate 4 can move along neck after sidepiece apron plate 1, sidepiece, backplate by
Backplate drive cylinder 3 drives, and can be sequentially inserted into piecemeal in the anterior excavation soil body 22, when each piece of backplate moves alone, oil cylinder
Pushing reaction provides counter-force by the frictional force of other positions and the soil body；By the independently moving of every piece of backplate, all shields can be promoted
Plate is forwardly inserted the soil body 22 to be excavated, and treats the supporting for excavating regional stability；Wedge-shaped plate 17 divides from top to bottom in installation site
For some pieces, driven by plate oil cylinder 18, region to be excavated can be inserted respectively；The anterior wedge structure of backplate and wedge-shaped plate 17
The soil body for tunneling blind area is extruded to driving region；Mole 16 is multigroup according to excavation width setting, and wedge is set between every group
Shape plate 17；Mole 16 is driven by drive device, and drive device is hydraulic motor or motor, is amplified by reductor and turned round
Square, driving chain type cutting band operating, chain type cutting band installation cutting tool and scum board, the soil body 22 to be excavated is cut away, and by
Scum board promotes, and moves to top slag notch with chain type cutting band, then dregs falls to front strap machine 15 and with sidepiece skin
Band machine 14, tail pulley machine 13 move to afterbody and have laid the top of tube coupling 12, and filling, unnecessary soil are formed to tube coupling top and sidepiece
Body can be transported to other places by slag-soil truck.Mole 16 is arranged in front support 2, is designed chute and articulated structure, is matched somebody with somebody
Hydraulic oil cylinder driving is closed, can be moved forward and backward relative to supporting shield body, its relative angle with horizontal plane can be adjusted, and be applied to excavation
Pressure on face can be adjusted by oil cylinder, and the stable of excavation face is supported so as to realize；The rear design of mole 16 has dividing plate 19,
Front portion is excavated and separated inside region and rear portion shield body, prevents excavation face mobility dregs or water body from largely entering inside shield body.
When mole 16 and front support 2 travel forward, thrust is provided simultaneously by backplate drive cylinder 3, now backplate
Frictional force, afterbody pressing plate 9 with the outside soil body can provide reaction of bearing；Pass through the forward and inner supporting structure successively of backplate
With the alternating movement of mole 16, you can realize that equipment is overall and walk certainly.
Be hinged by steering cylinder 5 between front support 2 and back support 7, steering cylinder 5 is arranged in space to be divided into
Lower four groups of left and right, by controlling the extension elongation of left and right side guard plate, and the thrust size of the left and right sides of steering cylinder 5, realize left and right
The control of steering.By controlling the size of steering cylinder pushing force about 5, the adjustment of posture above and below shield body is realized.
It is in square shape structure that back support 7, which is overlooked, and prefabricated tube coupling 12 can be hung in from top, is carried out assembled.In back support 7
Design prefabricated tube coupling aligning guide in portion, in that context it may be convenient to which prefabricated tube coupling 12 is arranged on mounted tube coupling；Prefabricated tube coupling
Before 12 liftings, bottom can lay bed course 20, and stable support is formed to piping lane；The rear portion both sides of back support 7 set afterbody pressing plate
9, driven by pressure plate cylinder 8, can counter-lateral quadrents backfill 11 apply pressure and make it more closely knit firm.Then tube coupling top is backfilled
Soil 21 carries out the laying operation that piping lane is completed in smooth compacting.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
