The specific embodiment
Embodiments of the invention: during the lining concrete of big section water conservancy project cavern, carry out in two steps, the first step earlier with every circulation 12 m, finishes the whole lining cutting of the side wall concrete of whole cavern; In second step,, finish the whole lining cutting of crown concrete of whole cavern equally with every circulation 12 m.Be that the whole lining cutting in whole cavern finish.
Stand main body 1 is by rod member 1-1, and junction plate 1-2 is assembled.
Bottle gouard moved by hands 3 adopts the 10t bottle gouard moved by hands.
The first adjustable push rod 4 adopts the helical screw structure.
The step of abutment wall lining concrete:
(1) stand main body 1 is in place, with stand main body 1 jack-up, tetrafluoro slide plate 5-2 is installed with hydraulic jack, lays lower skateboard 5-3; Hang ground to sidewall template 2 with bottle gouard moved by hands 3, the first adjustable push rod 4 fixed edge wall forms 2, hoist engine is pulled to first to stand main body 1 through assembly pulley and treats the lining cutting position.Take away tetrafluoro slide plate 5-2, lower skateboard 5-3; Below each root montant spare on stand main body 1 ground, beat that timber wedge is fixed and load, the rod iron (ground anchor peg) that 1 braking of stand main body is used wire rope to utilize underplate concrete to reserve and buried underground in the grout hole is fixing.
(2), carry out contraposition, the formwork erection of sidewall template 2, and bear the perfusion lateral force by the first adjustable push rod 4 with the bottle gouard moved by hands 3 and the first adjustable push rod 4; Install the thick hard rubber bar of 2cm in sidewall template 2 bottoms, prevent spillage and conveniently stripped.When the independent pouring construction of abutment wall, at four angles, two sidewall templates, 2 tops four jack are set altogether, hold out against with the arch country rock vertically upward, prevent that sidewall template 2 moves on taking place to float in concrete placement, influence casting quality.
(3) with distribution device 6, through concrete placing boom 6-1, tumbling barrel 6-2 is the symmetry concrete perfusion on the abutment wall both sides, and promptly both sides replace concrete perfusion, pour into the 40cm height at every turn, artificial stamped concrete.
When (4) treating that concrete reaches certain intensity, next one circulation is carried out in the demoulding again, and each lining cutting 12m is long, until accomplishing the whole lining cutting of abutment wall.
When the crown lining concrete, crown stand 7 is combined into one with crown template 8, this part relatively stand main body 1 move up and down.Also have crown mobile device 9, the second adjustable push rod 4-1, oil cylinder 10, hydraulic system 11 is handled oil cylinder adjustment crown template.
Crown stand 7 is by column 7-1, side lacing wire 7-2, and last longeron 7-3 and crossbeam 7-4 form.
Crown template 8 adopts the A3 steel plate of δ=6mm to make panel, and vertically ribs adopts [14a channel-section steel weldering system, the wide 2m that is.Totally 36 of a complete set of crown templates, 24 large forms wherein, arc length 4m connects through high-strength bolt each other; 12 little template 8-1, arc length 46.5cm is arranged in the wall displacement place of keeping to the side, both sides; Adopt high-strength bolts to be connected with large form through three hinges, can rotate up and down, be convenient to adjust little template lower end and abutment wall the concreting face be adjacent to; Diameter of bolt hole is φ 23mm, and bolt and nut are φ 22mm.Every template edge uses the A3 steel plate enclosure of 4 δ=11mm to be linked to be an integral body.
Crown mobile device 9, by oil cylinder seat 9-1, slideway 9-2 forms, and installs roller below the oil cylinder seat 9-1 that crown template 8 is moved up and down.
The concrete 12 that is pouring into, the ground concrete 13 that has poured into, the side wall concrete 14 that has poured into.
The step of crown lining concrete:
(1) hydraulic system 11 is handled oil cylinder 10 and cross cylinder 10-1 adjustment crown template 8, carries out contraposition, the formwork erection of crown template 8.
(2) the symmetry concrete perfusion on the abutment wall both sides, artificial stamped concrete.
When (3) treating that concrete reaches certain intensity, next one circulation is carried out in the demoulding again, and each lining cutting 12m is long, until accomplishing the whole lining cutting of crown.
