Dynamic, it is to avoid electric block track 13 hinders outer template 15 to walk on tie-beam 4.
Specific construction step is as follows:
Step one,
1st, according to this project construction field geology situation, basement process is carried out using cushion；
2nd, after excavator becomes silted up, change and fill out 1 meter of thick Base with Sand Gravel Cushion and be compacted reach intensity requirement.
Step 2,
1st, assembled all round victory support on ground；
2nd, aqueduct bed die and framework of steel reinforcement are installed on all round victory support, lay for the first time two span length's degree aqueduct bed die and
Framework of steel reinforcement, before should ensure that each nose girder walking afterwards, next is across bed die and framework of steel reinforcement installation；
3rd, adopt crane by assembled formwork system on template system lifting component to all round victory support.
Step 3,
1st, pour aqueduct base plate, underplate concrete top surface should be avoided to be higher than interior eight character matrix plates；
2nd, underplate concrete both not up to pre-hardening states, base plate position no concrete when ensuring that two side channel bodies pour are treated
When excessive, pour two side channel bodies.Should ensure that in casting process that concreting is carried out continuously；
3rd, concreting finishes, health preserving.
Step 4,
2nd, pack up the channel-section steel that stretches between inner template, remove between outer template to pulling plug；
3rd, interior eight character matrix plates are packed up by leading screw；
4th, it is deformed for upper end tie-beam after preventing exterior sheathing from opening, inner template cannot be opened, and first passes through internal model hydraulic pressure
Inner template opened by oil cylinder, then opens outer template by external mold hydraulic jack；
5th, remove connecting pins between internal model hydraulic jack and internal model truss, pack up internal model hydraulic jack；
6th, workmen can be using hanging box to pouring the aqueduct completing and template carries out modifying, polishes；
Step 5,
1, as shown in figure 3, very raising nose girder by very heavy, nose girder support is taken out and is placed on next across aqueduct groove pier top
Portion, should be across the aqueduct front end base plate position pouring molding, as shown in Figure 4 by rear end two downside power gear box dislocation.
2nd, fixing form frame system, opens upper and lower side power gear box, and upside power gear box inverts, downside power gear
Case rotates forward, and makes nose girder walk next across nose girder front end is propped up and stood on nose girder support 6, as shown in Figure 2.
3rd, open upside power gear box, upside power gear box rotates forward, make form frame system go to next nose girder is up
Across.
Step 6,
1st, eight character matrix plates in leading screw Zhi Li are passed through；
2nd, connecting pins between internal model hydraulic jack and internal model truss are installed, fixing internal model hydraulic jack；
3rd, it is to prevent deformation effect inner template Zhi Li that during exterior sheathing opening, upper end tie-beam produces, first pass through external mold
Hydraulic jack props up vertical exterior sheathing, then props up vertical inner template by internal model hydraulic jack；
4th, install inner template between support telescopic channel-section steel, exterior sheathing to pulling plug；
5th, repeat above step, carry out next across aqueduct construction.
Above example is only a kind of present invention embodiment therein, and its description is more concrete and detailed, but can not
Therefore it is interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art,
Without departing from the inventive concept of the premise, some deformation can also be made and improve, these broadly fall into the protection model of the present invention
Enclose.Therefore, the protection domain of patent of the present invention should be defined by claims.
