Description
Technical field
The present invention relates to lining construction field, and in particular to one kind is built for mould of highway and railway loess tunnel
The formwork jumbo of concreting.
Background technology
, it is necessary to carry out preliminary bracing after tunnel excavation shaping.Current Tunnel generally uses New Austrian Tunneling Method principle
Bolt-spary supports form.But to the special geology structure such as collapsible loess, not fully it is applicable using combined bolting and shotcrete, it is domestic at present
Outer loess tunnel starts to build concrete- liner using a mould and secondary mould builds this composite lining mode of concrete- liner, and a lining mould builds concrete
Construction typically uses small punching block assembling construction, that is, by manually carrying out the peace of fritter steel form and form bracing system after the completion of excavating
Dress, template assembly carries out concrete placings construction after the completion of reinforcing, this kind of construction method is big because of tunnel cross-section, and fritter punching block quantity is more,
Line style is difficult to control to, while workman's set-up time is long, causes personnel in the excavation face lower work time for having chip off-falling incipient slump damage
It is long, therefore this method mechanization degree is low, consumption labour is more, construction speed is slow, working security is poor.
The content of the invention
It is mixed to simplify it is an object of the invention to provide a kind of hydraulic template trolley suitable for loess tunnel once lining
Solidifying soil, which is poured, applies operating process, overcomes the shortcoming of original conventional construction method, saves manpower from basic realize, improves production

To) 2.2m, template beam overall 4.4m；Each lining cutting pours 2.2m, and two pieces of templates are poured in turn.
The course of work of the present invention is as follows：
(1) formwork erection：
After the completion of tunnel excavation, before lining cutting, formwork jumbo is drawn to lining cutting position and starts formwork erection, formwork erection front template platform
Car is in demoulding state, is now connected between the backform and formwork-support of template by latch.Referring to Fig. 1, Fig. 2, formwork erection press with
Under several steps carry out：
A, by hoist engine 15 draw formwork-support 6 move, template lengthwise position is adjusted in place；
B, startup hydraulic electric motor, the operation vertical oil cylinder 12 of hydraulic jumbo rise, and portal rise makes template 8 close predetermined
Highly；
C, the horizontal lateral pushing template 8 of oil cylinder 13 of operation, template is adjusted to its center line and tunnel-liner center line pair
Together；Then operate vertical oil cylinder 12 to rise again, template 8 is reached predetermined altitude；
D, the installation chassis support jack 21 on lower longeron lower ground, make it hold out against longeron under chassis upwards, make platform
Wheel tire is in the state that do not stress；
E, installation and adjusting template lateral support leading screw 20, hold out against side template, side template is reached perfusion state；
G, it is small install small on ground below mould while vertical jack 22 over the ground of mould, it is held out against small side mould upwards.Most
After bulkhead is installed.Formwork erection is completed.
(2) casting concrete：
Formwork erection can carry out concreting after completing.First pour above one piece of template.Before concreting, template
Outer surface smearing release agent, to reduce the surface viscous force during demoulding.When pouring, first carried out from one working window of template bottom,
Pour to concrete soon concordant operation window when, close working window, then poured from a upper operation window, successively upwards
Pour, bound finally by grouting port.After the completion of previous piece of template is poured, latter piece of template is poured with same method.
(3) it is stripped：
When previous piece of template concrete setting is to design requirement, start the demoulding.The demoulding is carried out by the following steps：
A, the shuttering supporting leading screw for previous template of dismantling, small side mould vertical jack and bulkhead over the ground；
B, remove connecting bolt between the backform and support frame of latter template；
C, referring to Fig. 4, connect the cucurbit chain on the small side mould and portal of previous template using chain block chain 23
Connector, operation chain block first packs up small side mould, then receives big side mould, then packs up the chassis support thousand below longeron under stand
Jin top, makes chassis weight be placed in by vertical oil cylinder on tire.
D, vertical oil cylinder is gradually tapered up, the backform of previous template is also departed from lining cutting surface, complete the demoulding of monoblock template.
(4) template is walked：
As shown in figure 4, after the previous piece of template demoulding, its backform height is highly lower than the backform of latter piece of template, and its is large and small
Side mould is also due to chain block chain 23 is tightened up in contraction state.Now latter template is in released state with chassis.Traction
Chassis moves forward the distance of the width of one piece of template, and now previous template is moved to the lower section of latter template with chassis.Start
Hoist engine, traction formwork-support slides the distance of one piece of template width along guide rail, drives previous piece of template from latter piece of template
Lower section is passed through, and reaches latter piece of template rear, then by same formwork erection process, its formwork erection is poured.Now foregoing is forward and backward
The position of template has been exchanged.Treat that latter piece of foregoing template has reached demoulding strength, then be stripped, walked, so follow repeatedly
Ring formwork erection, pour concrete, the demoulding, chassis walking, template and walk this five courses of work, until completing the lining cutting in whole tunnel.
