Two, stratified construction
In the subway work of the present embodiment, station main body side wall construction point 2 layers: negative two layers of side wall, negative one layer of side wall. Every layer of side wall is divided into 14 sections according to construction drawing, i.e. SS01～SS14, and side, each standard paragraphs north and south is respectively arranged with one section of side wall (except SS01, SS14). Negative two layers, negative one layer of side wall construct after having built at base plate, middle plate respectively.
Three, the processing of all-steel big shuttering and English truss
1, template processing
Side wall template adopts piecemeal punching block spelling to become large form, negative two layers adopt 3 × 3 pieces of wide 1.2m ×+3 × 1 piece of P3012 spellings of high 1.5m punching block, negative one layer adopts 3 × 3 pieces of wide 1.5m ×+3 × 2 pieces of P3015 spellings of high 1.2m punching block, template back arris all adopts work 10, Two bors d's oeuveres groove 10, with the fixing all-steel big shuttering 12 of gib headed bolt 8 and spot welding and back cord locking device 11.
Side wall support adopts shaped steel English truss, main rod member adopts H150 × 150 × 7 × 10, Two bors d's oeuveres groove 20b, work 16, Φ 32 reverse drawing shackle 9 back-pressure that English truss passes through to be embedded on base plate is to balance lateral pressure when concrete 4 is built, back-pressure crossbeam 18 adopts Two bors d's oeuveres groove 16b, simultaneously at support rear with jail, adjustable thrust jacking 15 stretching top.
2, installation of embedded parts
At each 30cm place, every Pin English truss both sides, the pre-buried reverse drawing shackle 9 in position of distance side wall 25cm, built-in fitting adopts Φ 28, and processing in inverted U-shaped, imbeds the long 55cm of bottom parts, the long 8cm in exposed portion. Pre-buried row's Φ 32 reinforcing bar at sub-truss rear simultaneously, spacing 40cm, as thrust steel 17 muscle, H150 × 150 × 7 × 10 thrust beam 16 is placed in thrust reinforcing bar 17 front, and every Pin English truss holds out against thrust beam 16 by two adjustable thrust jackings 15.
3, model sheetinstallat
The installation steps of template: play exterior wall sideline → side wall waterproof and reinforcing bar binding and check and accept → close outer wall template → one side formwork support transfer in place → concrete placings after single side bracing → adjustments support vertical degree → installations back-pressure gib headed bolt → fasten again embedded part system → acceptance(check) of inspection is installed.
In above-mentioned steps, when closing wall form, align in the wall sideline that template end opening is good with bullet in advance, then installs steel pipe back cord, is propped up by wall form with steel pipe temporarily; English truss is one group by 5 Pin and carries out spelling, installs four road wheels, can move along the rail 7 of base plate paving, when English truss group moves to side wall position to be poured, then with 16t gantry crane hoisted in position under often organizing truss; After English truss group is in place, with gib headed bolt 8, template back arris and single side bracing part is linked to be an entirety, and regulates single side bracing rear support, until form surfacing is suitable for reading to the about 10mm that inclines within the walls; Gib headed bolt 8 between locking back-pressure crossbeam 18 and pre-buried reverse drawing shackle 9, finally fastens and checks that a built-in fitting is by Force system, it is ensured that during concrete placings, template end opening will not spillage again.

8. the construction method of side wall self-propelled English truss according to claim 6, it is characterized in that, in described step S3, English truss is one group by 5 Pin and carries out spelling, four road wheels are installed under often organizing truss, can move along the rail of base plate paving, when English truss group moves to side wall position to be poured, then with 16t gantry crane hoisted in position; After English truss group is in place, with gib headed bolt, template back arris and single side bracing part is linked to be an entirety, and regulates single side bracing rear support, until form surfacing is suitable for reading to the about 10mm that inclines within the walls; Gib headed bolt between locking back-pressure crossbeam and pre-buried shackle, finally fastens and checks that a built-in fitting is by Force system, it is ensured that during concrete placings, template end opening will not spillage again.
9. the construction method of side wall self-propelled English truss according to claim 6, it is characterised in that in described step S5, specifically include step:
S51: play exterior wall sideline;
S52: side wall waterproof and reinforcing bar binding are also checked and accepted;
S53: close outer wall template;
S54: the transfer of one side formwork support is in place;
S55: install single side bracing;
S56: regulate support vertical degree;
S57: install back-pressure gib headed bolt;
S58: fastening checks an embedded part system again;
S59: concrete placings after acceptance(check).
10. the construction method of side wall self-propelled English truss according to claim 9, it is characterised in that in described step S5, when closing outer wall template, aliging in the wall sideline that template end opening is good with bullet in advance, then installs steel pipe back cord, propped up by wall form with steel pipe temporarily.
