1 and 2 liang of big structures of mould bases, the mould bases 2 is supported and is walked on the nose girder 1.
The nose girder 1 is that two spans are long, and nose girder 1 is spliced into entirety using beret slice and connecting rod, and beret slice intensity is high, just
Degree is big.The nose girder front end is supported in aqueduct slot pier top portion by nose girder holder 6, and the nose girder centre and rear end are dynamic by downside
Powershift gear case 7 is supported in one across on pouring molding aqueduct bottom plate front end and rear end supporting member 18, concrete structure such as Fig. 2
It is shown.To avoid power gear box from damaging aqueduct bottom plate, gear-box should be positioned over above aqueduct slot pier at bottom plate position, and
About 18 supporting member is large-area steel plate between gear-box and aqueduct bottom plate, can increase forced area.
The mould bases 2 includes external mold truss 14, exterior sheathing 15, internal model truss 16, inner template 17, tie-beam 4, flexible channel steel
19, pulling plug 23 is formed.The toed-in template 22 is connect using folding, it can be achieved that toed-in template rotates with inner template 17
It opens, toed-in template is conducive to inner template after being flipped open and smoothly opens.The exterior sheathing 15, the welding of 17 outside of inner template are horizontal
To continuous channel steel, the continuous channel steel is all made of and is bolted with the external mold truss 14, internal model truss 16, is bolted and is convenient for
Dismounting, recycling and transport.Entirety is formed by the tie-beam 4 between template, tie-beam 4 is I-steel, tie-beam 4 with
Truss is connected using traveling wheel 9 below.In order to disperse below tie-beam pulling force between truss and template, external mold truss 14,
Oblique and horizontal brace rod is set between internal model truss 16, makes all truss entirety stress.Pass through between the exterior sheathing 15
Pulling plug 23 is fixed and is supported, pulling plug is arranged as shown in Figure 9, Figure 10；It is fixed by flexible channel steel 19 between the inner template 17
Support, the flexible channel steel are that big model channel steel covers ting model channel steel, and the two is fixed by pin, concrete structure such as Figure 14 institutes
Show.
Mould bases 2, which is opened, mainly to be realized by hydraulic cylinder and leading screw, and hydraulic cylinder is connected using axis pin.External mold hydraulic cylinder
8 one end are connected on the tie-beam 4, and one end is connected at the external mold truss 14 in connecting rod；Internal model hydraulic cylinder 20 1
End is connected at the internal model truss 16 in connecting rod, and one end is connected at the nose girder 1 in connecting rod；For opening toed-in
21 one end of leading screw of template 22 is connected on the internal model truss 16, and one end is connected on eight character matrix plates 22.Specific mould bases Zhi Li
Structure is as shown in Figure 5, Figure 7, and mould bases opening structure is as shown in Fig. 6, Fig. 8.
Nose girder 1 and the walking of mould bases 2 realize that about 1 nose girder is all connected with rail 12 by power gear box, and rail connects
Binding composition is as shown in figure 11, and the power gear box is walked on rail 12.Upside power gear box 11 is fixed on tie-beam 4
On, downside power gear box 7 is positioned at aqueduct floor on supporting member 18.
Modification polishing aqueduct concrete and template are mainly realized by electric block 10 and hanging box 24, below electric block 10
Hanging box 24 is connected, electric block track 13 is I-steel, is connected using traveling wheel between the electric block track 13 and tie-beam 4
It connects, connecting rod is set between electric block track 13 and external mold truss 14, realize that electric block track is synchronous with outer template and move
It is dynamic, avoid electric block track 13 that outer template 15 is hindered to walk on tie-beam 4.
Steps are as follows for Specific construction：
Step 1:
1, according to this project construction field geology situation, basement process is carried out using cushion；
2, it after excavator becomes silted up, changes and fills out 1 meter thick Base with Sand Gravel Cushion and be compacted reach intensity requirement.
Step 2:
1, the assembled all round victory holder on ground；
2, aqueduct bed die and framework of steel reinforcement are installed on all round victory holder, place for the first time two span length's degree aqueduct bed die and
Framework of steel reinforcement should ensure that next before the walking of each nose girder installation is complete across bed die and framework of steel reinforcement later；
3, using crane by assembled formwork system on template system lifting component to all round victory holder.
Step 3:
1, aqueduct bottom plate is poured, underplate concrete top surface should be avoided to be higher than toed-in template；
2, underplate concrete both not up to pre-hardening states are waited for, ensure that bottom plate position is without concrete when two side channel bodies pour
When overflowing, two side channel bodies are poured.It should ensure that concreting is carried out continuously in casting process；
3, concreting finishes, health.
Step 4:
2, the channel steel that stretches between inner template is packed up, is removed between outer template to pulling plug；
3, toed-in template is packed up by leading screw；
4, it is that upper end tie-beam is deformed after preventing exterior sheathing from opening, inner template can not open, and first pass through internal model hydraulic pressure
Oil cylinder opens inner template, then opens outer template by external mold hydraulic cylinder；
5, connecting pins between internal model hydraulic cylinder and internal model truss are removed, internal model hydraulic cylinder is packed up；
6, construction personnel can modify the aqueduct and template that have poured completion using hanging box, polish；
Step 5:
1, as shown in figure 3, very raising nose girder by very heavy, the taking-up of nose girder holder is placed on next across aqueduct slot pier top
Portion, should be across the aqueduct front end bottom plate position of pouring molding, as shown in Figure 4 by the downside power gear box dislocation of rear end two.
2, fixed form frame system opens upper and lower side power gear box, the reversion of upside power gear box, downside power gear
Case rotates forward, and makes nose girder walking to next across nose girder front end Zhi Li is on nose girder holder 6, as shown in Figure 2.
3, upside power gear box is opened, upside power gear box rotates forward, and so that form frame system is gone in nose girder uplink next
Across.
Step 6:
1, it is propped up by leading screw and founds toed-in template；
2, connecting pins between internal model hydraulic cylinder and internal model truss, fixed internal model hydraulic cylinder are installed；
The deformation effect inner template Zhi Li that upper end tie-beam generates when 3, to prevent exterior sheathing open state, first passes through external mold
Hydraulic cylinder branch founds exterior sheathing, is then propped up by internal model hydraulic cylinder and founds inner template；
4, install inner template between support telescopic channel steel, exterior sheathing to pulling plug；
5, above step is repeated, is carried out next across aqueduct construction.
The above example only one such embodiment of the present invention, the description thereof is more specific and detailed, but can not
Therefore it is interpreted as the limitation to the scope of the claims of the present invention.It should be pointed out that for those of ordinary skill in the art,
Without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection model of the present invention
It encloses.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
