Detailed description of the invention
As shown in Figure 1-2, preparation hole outline line (3) is the outline line of preparation hole Dong Bi (4), section of jurisdiction internal diameter profile line (1), section of jurisdiction external diameter outline line (2), outline line for section of jurisdiction, monomer reaction frame (5) is arranged between section of jurisdiction internal diameter profile line (1), section of jurisdiction external diameter outline line (2).Each monomer reaction frame (5) along preparation hole Dong Bi (4) circumferentially; Monomer reaction frame (5) is uniformly distributed in preparation hole Dong Bi (4), directly over arrange 1 group, arranged just beneath 2 groups, the left and right sides is arranged symmetrically and evenly, ensure that position corresponding to each block section of jurisdiction all has monomer reaction frame (5) to support simultaneously,, section of jurisdiction piecemeal difference different according to TBM digging diameter, the corresponding adjustment of number needs of monomer reaction frame (5).
Monomer reaction frame (5) is anchored in preparation hole Dong Bi (4) by anchor pole (6), and makes monomer reaction frame (5) press preparation hole Dong Bi (4) with certain pretightning force by nut (7), pad (8).Closely knit between preparation hole Dong Bi (4) and monomer reaction frame (5), cavity and loose media must not be there is, to ensure that the shield formula TBM counter-force that starts is offset by frictional force therebetween, otherwise anchor pole will owing to being cut, bending and lost efficacy, cause reaction frame bulk deformation.
Anchor pole (6) length is not less than 2m, and diameter is not less than 25mm, and concrete specification is determined according to TBM digging diameter, preparation hole wall rock condition, the counter-force that starts.
As in Figure 3-5, monomer reaction frame (5) is made up of reaction plate (9), semi girder (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 construction; One end of semi girder (10) is welded in the cantilever construction of Ji Liang (11), and the other end of semi girder (10) is cantilever construction; The end face weld of semi girder (10) is connected to reaction plate (9); Diagonal brace (13) is increased between reaction plate (9) and semi girder (10) or between reaction plate (9) and Ji Liang (11).
Above-mentioned 5 parts are firmly welded as a whole, and weld seam requires full weld, full, zero defect, and weld bead height is determined according to parent selection and force analysis.
Form each monomer reaction frame (5) of reaction frame system when preparing the upper anchoring of hole Dong Bi (4) and installing, each reaction plate (9) is on same perpendicular.
Pedestal (12) steel plate thickness is not less than 20mm, and the uniform through hole in the left and right sides and rear portion, in order to skyhook (6).Room should ensure that there is suitable spacing at steel plate edge, to guarantee intensity, ensures again to keep suitable spacing, so that clamp nut (7) between Ji Liang (11).
As Fig. 3, Ji Liang (11) and semi girder (10) are advisable with H profile steel, its specification can be determined according to TBM digging diameter, the distance between section of jurisdiction and Dong Bi (4), the TBM counter-force that starts, except the requirement of structural strength, rigidity aspect, the center line of semi girder (10) and reaction plate (9) and section of jurisdiction thickness center line also to be made to be consistent.If because bulk reason cannot choose the shaped steel of appropriate size, Plate Welding can be adopted to become H type or box-structure.
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; Diagonal brace (13) is increased to strengthen structural stability between reaction plate (9) and semi girder (10) or between reaction plate (9) and Ji Liang (11).
