Retraction, Cheng Xue mechanism 3 bounces back therewith, so that inclined wedge support shoe apparatus be pulled to advance 1 together in the case where pulling the drive that oil cylinder 20 bounces back
The distance of endless tube piece.Then, Cheng Xue mechanism 3 continues stretching hole wall, and the stretching of propelling cylinder 7, which is held out against, is managing on behalf of another 1 front end surface of loop,
1 endless tube piece is continued to complete apart from stepping.Wherein, pull that the front end of oil cylinder is hinged with joist and rear end is hinged with walker.
In addition to above-mentioned inclined wedge supports shoe apparatus 21, the utility model additionally provides shield machine, shield machine specifically include shield body 6,
The duct piece assembling machine 10 inclined wedge support shoe apparatus 21 and be detachably arranged in the shield body 6, inclined wedge support shoe apparatus 21 can be
Inclined wedge provided by any of the above-described embodiment supports shoe apparatus 21.The shield machine specifically includes shield machine in carrying out work progress
Promote mode to there is pipe from no section of jurisdiction from the process and shield machine for having section of jurisdiction that mode is promoted to promote mode to convert to no section of jurisdiction
Piece promotes the process of mode conversion.It is a set of dismountable counterforce device for shield machine that inclined wedge, which supports shoe apparatus 21, is solved
The problem of construction difficult problem and shield machine economy of shield machine " standing after first tunnel " excavate station, expands geology adaptation range, drops
Low constructing tunnel cost, may be implemented " a tractor serves several purposes ", improves driving speed.The cutterhead 5 of the shield machine, main driving 8, spiral shell
Revolving the structures such as conveyer 11, duct piece assembling machine 10, trailer idler wheel 16, refer to the prior art, and repeats no more herein.
It is a kind of to carry out the construction method that shield machine is tunneled without pipe sheet assembling, Specific construction mistake using above-mentioned inclined wedge support shoe apparatus
Journey is as follows:
One, fig. 4 to fig. 6 is please referred to, this three figures illustrate earth pressure shield tunneling machine from there is section of jurisdiction that mode is promoted to push away to no section of jurisdiction
The process of progressive die formula conversion, specific mode flow path switch (technique) are as follows:
Step 1: in the assembled 14 front end assembly transition rings section of jurisdiction 17 (i.e. steel pipe ring) of tunnel duct piece completed and added
Gu.It is by duct piece assembling machine 10 that transition rings section of jurisdiction 17 is assembled cyclic, it is ensured that vertical between transition rings section of jurisdiction 17 and tunnel duct piece 14
It is fastened to the connection of bolt.Seal ring 19 is installed additional in 17 front end of transition rings section of jurisdiction, prevents stratum from seeping water.It is carried on the back to transition rings section of jurisdiction 17
Packing material 13 after the injection wall of face gap squeezes into anchor pole 18 toward tunnel wall surface, squeezes into quantity and select as needed.With regard to this, transition
Endless tube piece 17 is completed to reinforce.Wherein, tunnel duct piece 14 includes section of jurisdiction piecemeal 1401.
Step 2: installation inclined wedge supports shoe apparatus 21.According to the sequence for managing on behalf of another loop 1-posture oil cylinder 2-Cheng Xue of group mechanism 3
Inclined wedge is installed and supports shoe apparatus 21, fastens between arc-shaped steel section of jurisdiction 101 and arc-shaped steel section of jurisdiction 101, posture oil cylinder 201 and manage on behalf of another loop
Connection bolt or other attachment devices between 1 and force transmission rack 301, between each component of Cheng Xue mechanism 3,3 rear end one of Cheng Xue mechanism
Side should reserve certain adjustment gap between assembled transition rings section of jurisdiction 17.
Step 3: earth pressure shield tunneling machine is promoted without section of jurisdiction mode.Inclined wedge is being supportted into 21 all parts of shoe apparatus, hydraulic and electrical
Pipeline is after the installation is completed: 1. under the promotion of connection oil cylinder 304, and it is straight slowly to increase clamping force on the wall of hole for 3 stretching of Cheng Xue mechanism
To reaching design objective；2. stretching out propelling cylinder 7 until its end is pushed against and manages on behalf of another 1 end face of loop；3. by duct piece assembling machine 10
It returns to 9 front end of joist and locks；4. rotating cutter-head 5 simultaneously starts other systems, slowly 7 pressure of propelling cylinder is improved until pre-
Phase boring parameter, earth pressure shield tunneling machine start no section of jurisdiction driving；5. completing a digging distance (1 endless tube pitch of fins for a step cycle
From), it shuts down, connection oil cylinder 304 bounces back, and Cheng Xue mechanism 3 retracts；6. pulling oil cylinder 20 to bounce back, before dragging inclined wedge support shoe apparatus 21
Into a step cycle distance (1 endless tube piece distance), connection oil cylinder 304 extends, and 3 stretching of Cheng Xue mechanism promotes oil on the wall of hole
Cylinder 7, which is stretched out and held out against, is managing on behalf of another 1 end face of loop, starts next P. drechsleri.
Two, Fig. 6 to Fig. 8 is please referred to, this three figures illustrate earth pressure shield tunneling machine and promote mode to there is section of jurisdiction to push away from no section of jurisdiction
The process schematic of progressive die formula conversion, specific mode flow path switch (technique) are as follows:
Step 1: when shield machine soon goes out hard rock section, it is suitable that loop 1 is managed on behalf of another according to Cheng Xue mechanism 3-posture oil cylinder group 2-
Successively piecemeal removes inclined wedge support shoe apparatus 21 to sequence, installs transition rings section of jurisdiction 17 and is simultaneously reinforced (strengthening flow process is with aforementioned), is shield
Structure driving provides counter-force, and transition rings quantity should reach design requirement (generally no less than 2 rings).
Step 2: stop assembled transition rings section of jurisdiction 17, be changed to assembled tunnel duct piece 14.Wall is filled at 14 back side of tunnel duct piece
Packing material 13 afterwards, Strengthening Tunnel section of jurisdiction 14, earth pressure shield tunneling machine begin with section of jurisdiction propulsion.
