(5) it is arranged between section of jurisdiction internal diameter contour line (1), section of jurisdiction external diameter contour line (2).Each monomer reaction frame (5) along preparation hole Dong Bi
(4) circumferentially；
Monomer reaction frame (5) is anchored on prepared hole Dong Bi (4) by anchor pole (6), and passes through nut (7), pad (8)
Monomer reaction frame (5) is set to press prepared hole Dong Bi (4).
Monomer reaction frame (5) is made up of reaction plate (9), cantilever beam (10), Ji Liang (11), pedestal (12) and diagonal brace (13),
Ji Liang (11) is welded on pedestal (12), and Ji Liang (11) one end is cantilever design；One end of cantilever beam (10) is welded on Ji Liang
(11) in cantilever design, the other end of cantilever beam (10) is cantilever design；The end face of cantilever beam (10) is welded with reaction plate
(9)；Diagonal brace (13) is provided between reaction plate (9) and cantilever beam (10) or between reaction plate (9) and Ji Liang (11).
When each monomer reaction frame (5) anchors installation on preparation hole Dong Bi (4), each reaction plate (9) is in same vertical flat
On face.
Beneficial effects of the present invention：Split type reaction frame have simple in construction, lightweight, structural strength and rigidity it is reliable,
Occupy little space, make and the characteristics of install convenient, system peace cost more than 70% can be saved.

Embodiment
As shown in Figure 1-2, the contour line that prepared hole contour line (3) is preparation hole Dong Bi (4), section of jurisdiction internal diameter contour line (1),
Section of jurisdiction external diameter contour line (2), the contour line for section of jurisdiction, monomer reaction frame (5) is outside section of jurisdiction internal diameter contour line (1), section of jurisdiction
Between footpath contour line (2).Each monomer reaction frame (5) along preparation hole Dong Bi (4) circumferentially；Monomer reaction frame (5) is in preparation hole
Hole wall is uniformly distributed on (4), 1 group of surface arrangement, 2 groups of arranged just beneath, and the left and right sides is symmetrically and evenly arranged, while ensureing every
There is monomer reaction frame (5) support the corresponding position in one piece of section of jurisdiction, different according to TBM digging diameters difference, section of jurisdiction piecemeal, monomer
The quantity of reaction frame (5) need to be adjusted accordingly.
Monomer reaction frame (5) is anchored on prepared hole Dong Bi (4) by anchor pole (6), and passes through nut (7), pad (8)
Monomer reaction frame (5) is set to press prepared hole Dong Bi (4) with certain pretightning force.Preparation hole Dong Bi (4) and monomer reaction frame (5) it
Between it is closely knit, must not exist cavity and loose media, with ensure shield formula TBM originate counter-force by therebetween frictional force offset, it is no
Then anchor pole will fail due to being cut, bent, and cause reaction frame overall deformation.
Anchor pole (6) length is not less than 2m, and diameter is not less than 25mm, and The concrete specification is according to TBM digging diameters, preparation hole country rock
Condition, originate counter-force determination.
As in Figure 3-5, monomer reaction frame (5) by reaction plate (9), cantilever beam (10), Ji Liang (11), pedestal (12) and tiltedly
(13) composition is supportted, Ji Liang (11) is welded on pedestal (12), Ji Liang (11) one end is cantilever design；One end weldering of cantilever beam (10)
In the cantilever design for being connected on Ji Liang (11), the other end of cantilever beam (10) is cantilever design；The end face of cantilever beam (10) is welded with
Reaction plate (9)；Increase diagonal brace (13) between reaction plate (9) and cantilever beam (10) or between reaction plate (9) and Ji Liang (11).
Above-mentioned 5 parts are firmly welded as a whole, level weld seam requirement full weld, full, zero defect, and weld bead height is according to mother
Body selection and force analysis are determined.
When each monomer reaction frame (5) for constituting reaction frame system anchors installation on preparation hole Dong Bi (4), each reaction plate
(9) on same perpendicular.
Pedestal (12) steel plate thickness is not less than 20mm, the uniform through hole in the left and right sides and rear portion, to install anchor pole (6).It is empty
Position should ensure that there is appropriate spacing at steel plate edge, to ensure intensity, ensure to keep appropriate spacing between Ji Liang (11) again,
In order to clamp nut (7).
Such as Fig. 3, Ji Liang (11) and cantilever beam (10) are advisable with H profile steel, its specification can according to TBM digging diameters, section of jurisdiction and
The distance between hole wall (4), TBM originate counter-force determination, in addition to the requirement in terms of structural strength, rigidity, also to make cantilever beam
(10) it is consistent with the center line of reaction plate (9) with section of jurisdiction thickness center line.If because bulk reason can not choose conjunction
The shaped steel of suitable specification, can be welded into H types or box-structure using steel plate.
Reaction plate (9) thickness is not less than 20mm, and width is not less than section of jurisdiction thickness, and length is not less than 40cm；Reaction plate (9) and
Increase diagonal brace (13) between cantilever beam (10) or between reaction plate (9) and Ji Liang (11) with enhancing structure stability.
