Below pass through concrete Application Example of the utility model, by reference to the accompanying drawings, to structure of the present utility model and the course of workBe elaborated. In the present embodiment, chassis support body is (along tunnel direction) long 6.8m longitudinally, two templates, every wide (edgeChassis is longitudinal) 2.2m, template beam overall 4.4m; 2.2m is built in each lining cutting, and two templates are built in turn.
The utility model course of work is as follows:
(1) formwork erection:
After tunnel excavation completes, before lining cutting, formwork jumbo is drawn to lining cutting position and starts formwork erection, formwork erection front template chassis placeIn demoulding state, now between the backform of template and formwork-support, be connected by latch. Referring to Fig. 1, Fig. 2, below formwork erection is pressedSeveral steps are carried out:
A, draw formwork-support 6 by hoist engine 15 and move, template lengthwise position is adjusted to the right place;
B, primer fluid Medium-voltage Motor, the vertical oil cylinder 12 of operation hydraulic jumbo rises, and gate-type frame raises, and template 8 is approached predetermined highDegree;
C, operate horizontal oil cylinder 13 lateral pushing templates 8, template is adjusted to its center line and aligns with tunnel-liner center line;And then the vertical vertical oil cylinder 12 of operation rises, make template 8 reach predetermined altitude;
D, on ground, lower longeron bottom, chassis support jack 21 is installed, is made it upwards hold out against longeron under chassis, make chassis wheelTire is in the state of not stressing;
E, installation adjusting template lateral support leading screw 20, hold out against side template, makes side template reach perfusion state;
G, mould vertically jack 22 over the ground in little limit is installed on ground below the mould of little limit, is made it upwards hold out against little limit mould. Finally peaceDress bulkhead. Formwork erection completes.
(2) casting concrete:
After completing, formwork erection can carry out concreting. First build a template above. Before concreting, template appearanceFace smearing release agent, the surperficial viscous force when reducing the demoulding. While building, first from template the working window in below carry out, buildSoon when concordant operation window, close working window to concrete, then build from a upper operation window, upwards build successively,Finally bind by grouting port. After last template built, use the same method and build a rear template.
(3) demoulding:
Last template concrete setting during to designing requirement, starts the demoulding. The demoulding is undertaken by the following steps:
Vertically jack and bulkhead over the ground of the shuttering supporting leading screw of a, the last template of dismantling, little limit mould;
B, take off after connecting bolt between backform and the bracing frame of a template;
C, referring to Fig. 4, the cucurbit chain that utilizes chain block chain 23 to connect on little limit mould and the gate-type frame of last template connectsPart, operation chain block is first packed up little limit mould, then receives large limit mould, then packs up the chassis support jack of longeron below under stand,Chassis weight is placed on tire by vertical oil cylinder.
D, shrink vertical oil cylinder gradually, make the backform of last template also depart from lining cutting surface, complete the demoulding of monoblock template.
(4) template is walked:
As shown in Figure 4, after the last template demoulding, after its backform aspect ratio, the backform height of a template is low, its large and small limitMould is also because chain block chain 23 tightens up in contraction state. Now, a template and chassis are in released state. Traction tableCar moves forward the distance of the width of a template, and now last template moves to the below of a rear template with chassis. Start elevatorMachine, traction formwork-support, along the distance of a template width of guide rail slip, drives last template to wear from rear template belowMore, arrive a rear template rear, then by same formwork erection operation, by its formwork erection, build. Now aforesaid forward and backward templatePosition exchange. After aforesaid, a template has reached demoulding strength, then by its demoulding, walk, so iterative cycles is verticalMould, water concrete, the demoulding, trolley running, template and walk this five courses of work, until complete the lining cutting in whole tunnel.
