It is to be appreciated that as traditional shield machine, the utility model circumferential direction digs shield mechanism equally and has corresponding
Rear impact, Rear impact generally comprise pipe sheet assembling mechanism 200, control device 300, hydraulic transmission 400 and
Slagging mechanism 500, wherein pipe sheet assembling mechanism 200 is for realizing the circumferential direction for the section of jurisdiction for digging region and longitudinal direction (or axial)
Assembly, slagging mechanism 500 is used to for the dregs in native storehouse 4 being discharged, and is delivered to muck haulage vehicle 600 through Residue extraction pipeline 501, and by transporting
Navy barrow 600 transports tunnel.Distinguished with traditional shield mechanism, with the utility model circumferential direction dig shield mechanism it is corresponding after
Pipe sheet assembling mechanism 200 in corollary system is located at circumferential direction and digs outside shield mechanism, specifically, the corresponding region to be digged in former tunnel
The position in longitudinal two outside be equipped with portal frame 700, duct piece assembling machine 200 is installed on the longitudinal drive shaft 701 of portal frame 700
On, and can move during the work time under the driving of hydraulic transmission 400 along portal frame 700 to adjust its lengthwise position,
Slagging mechanism 500 is individually located at region side to be digged, and separates with hydraulic transmission and control device etc., can effectively keep away
Exempt from construction to interfere with each other, improves casting drivage efficiency
S5, circumferential direction dig shield mechanism circumferential direction tunnel one piece dig the distance of section of jurisdiction 102 after, stop driving, and will
It is longitudinal at least one piece assembled in the region just tunneled by pipe sheet assembling mechanism 200 after jacking mechanism 6 is separated with reaction frame 105
Dig section of jurisdiction 102；
Specifically, section of jurisdiction 102 is digged for longitudinal assembled how many pieces in the region just tunneled by pipe sheet assembling mechanism 200, it is main
Depending on circumferential direction digs the longitudinal size of shield mechanism, such as can be longitudinal assembled one piece, two pieces, three pieces, four pieces or more
It is more, as shown in fig. 6, the case where digging section of jurisdiction 102 for longitudinal assembled four pieces.
S6, jacking mechanism 6 and the rigid assembled section of jurisdiction 102 that digs are offseted, and drives circumferential direction to dig shield by jacking mechanism 6
Structure mechanism continues circumferential driving and cuts the soil body, meanwhile, the dregs for flowing into native storehouse 4 is discharged by slagging mechanism.
In the utility model embodiment, the medial surface of the side partition 2 and/or the side of middle partition 7 offer circular arc
The center of circle of shape slot 21,71, the arc-shaped slot 21,71 is located on the center line of substrate 1, and the jacking mechanism 6 includes multiple thousand
Jin top 62 and supporting boot 61, supporting boot 61 are connected to one end of corresponding jack 62, and the other end of jack 62 is connected with guiding
Part 63, guide part 63 are plugged in arc-shaped slot 21,71, when work, supporting boot 61 and reaction frame 105 or what is spliced dig
Section of jurisdiction offsets, to provide reaction of bearing when jack 62 stretches, so that the other end of jack 62 is by guide part 63 through circle
21,71 pairs of side partitions 2 of arc groove and/or middle partition 7 provide the thrust of circumferential driving, i.e., when jack stretches, by with support
Reaction frame that boots offset or the section of jurisdiction that digs spliced provide reaction of bearing, provide circumferential pick to side partition and/or middle partition
Into thrust, thus drive entire circumferential direction dig shield mechanism circumferential direction driving.Specifically, supporting boot 61 is articulated with jack 62
One end, guide part 63 are plugged in arc-shaped slot 21,71, and can be as needed before the circumferential driving of drive substrate 1 or ring
To adjusting guide part 63 during driving in the position of arc-shaped slot 21,71, to adjust the stress of partition and/or middle partition 7
Direction, and guarantee that circumferential direction digs shield mechanism and can protect circumferential driving.
In one preferred embodiment of the utility model, the both side surface of the medial surface of side partition 2 and middle partition 7 is opened respectively
Arc-shaped slot 21,71 equipped at least two concentrics (as shown in Figure 1, to open up the feelings of two arc-shaped slots 21,71 respectively
Condition), the arc-shaped slot 21,71 corresponding at least two of the both side surface of the medial surface of each side partition 2 and each middle partition 7 is very heavy
Top 62 (as shown in Figure 1, for the case where respectively corresponding two jack 62), one end of corresponding at least two jack 62 and branch
It supports boots 61 to connect jointly, the other end is connect jointly with guide part 63, and guide part 63 is plugged in corresponding at least two circular arcs
Shape slot 21,71.This set-up mode can make circumferential direction dig shield mechanism in tunneling process, obtain more uniform driving power.
S7, shield mechanism is digged in circumferential direction continue to stop driving after circumferential one piece of driving digs the distance of section of jurisdiction 102.
S8, it will just one piece of driving dig after section of jurisdiction 102 chisels apart from corresponding former section of jurisdiction 101 and clear up corresponding surflaes,
Jacking mechanism 6 is separated with section of jurisdiction 102 is digged, and continues assembled at least one piece by 200 longitudinal direction of pipe sheet assembling mechanism and digs pipe
Piece 102；
Specifically, in step s 8, longitudinal to continue to dig section of jurisdiction in the assembled quantity for digging section of jurisdiction 102 and step S5
102 quantity are consistent.
It is to be appreciated that after tunneling the distance that one piece digs section of jurisdiction 102 using every circumferential direction, then chisel corresponding former section of jurisdiction
101 and clear up the mode of surflaes, it is ensured that the structural stability of former 100 section of jurisdiction of tunnel prevents the excessive change in former 100 section of jurisdiction of tunnel
Shape.
S9, shield mechanism circumferential direction is digged by step S6 to S8 repetitive operation to circumferential direction tunnel to reentering and originate active well
103 (it should be noted that in step s 9, should last block of first not assembled circumferential direction dig section of jurisdiction)；
S10, circumferential direction is digged to mechanism, bracing members frame 104 and reaction frame 105 are disassembled and after removing and originating active well 103, into
Row concreting originates active well 103 to fill, and last assembled circumferential block digs section of jurisdiction 102, expands to complete a ring
Dig the assembled work of section of jurisdiction；
S11, it works by step S1~S10 repetitive operation to the assembled of section of jurisdiction that dig for completing region to be digged.Entire ring
It is not take up ground space to the process of digging, do not block the traffic and does not damage surface structures.In addition, the utility model circumferential direction digs
