Quality defect of concrete repaired in time, built-in fitting is handled；And arrange that a sprinkle water and spray fills on the downside of template 13
It sets, guarantee in time sprinkles water to the concrete for reaching initial setting strength, conserves.
In preferred embodiment, jack 11 is controlled by YKT-36 type hydraulic control panel, and console is in the commander of sliding mode system
The heart is that jack 1 provides power by oil pipe, control valve etc., and automatic leveling device is the synchronizing device of jack 1, is fixed on branch
It supports on thick stick, control is synchronized to jack 1 in due course, it is ensured that sliding formwork is horizontal, uniformly rises.
In preferred embodiment, 13 merogenesis of template is manufactured, and is bolted between section, and 13 length of template considers tunnel design point as a whole
Seam, reinforcing bar length, construction speed require etc. factors, be generally advisable with 10-20 meters, in order to pacify tear open, convenient transportation, can merogenesis system
It makes, is bolted between section.
In preferred embodiment, charging mechanism is provided on trolley 10, the charging mechanism includes hopper 4, multiple material-dividing grooves 3
With multiple movable joint chutes 6, each movable joint chute 6 is separately positioned on 10 two sides of trolley, and each 3 one end of material-dividing groove and each movable joint chute 6 connect
Logical, other end is connected to the hopper 4 that 10 top of trolley is arranged in, and concrete is directly sent to hopper 4 by concrete pump,
By material-dividing groove 3, movable joint chute 6 to 13 two sides uniform distributing of template, close a position, vibrate, mouth internal vibration over the pattern 13
Device effectively vibrates to concrete implementation.
Embodiment 2:
Template 13 makes: manufacturing in manufacturing shop by design requirement merogenesis, carries out an acceptance inspection after pre-assembled, merogenesis is numbered after qualification.
Reinforcement installation: can install in advance, can also with slding form operation while installation, while sliding formwork；Recommend first to pacify using reinforcing bar
Dress mode, in favor of rapid concrete construction.
Die body installation: merogenesis installation after all systems are installed, carries out no-load test.
The installation of concrete conveying system: after template 13 is in place, installing concrete hopper 4, material-dividing groove 3, movable joint chute 6,
Concrete pump, erection concrete pump pipe are installed in suitable position.
Concrete construction: concrete is transported using tank car, and concrete pumping to aggregate bin utilizes material-dividing groove 3, movable joint chute
It 6 symmetrically puts in storage, uniform point storehouse；It is important to guarantee that two sides side wall concrete is uniformly synchronized and put in storage, to ensure that side does not occur for template 13
It moves, and is uniformly vibrated using the layering of flexible axle shock club.Strict implement sequence put in storage, be layered close a position, uniformly vibrate, synchronize it is sliding
Principle.
Sliding formwork is sliding: concrete pour for the first time it is first sliding with sliding formwork, strictly by following six step carry out: for the first time
Pour the concrete or mortar of 10cm thickness, half aggregate；Then the second layer concrete is poured no more than 30cm by lift height；Thickness
When reaching 70cm, start sliding 3~6cm, checks whether demoulding concrete intensity is suitable.4th layer pours rear sliding 6cm, continues
Layer 5 sliding 12cm~15cm again is poured, layer 6 pours rear sliding 20cm, if phenomenon without exception, can normally be poured
With it is sliding.Concreting is symmetrically poured using layering, and lift height is not more than 30cm.Sliding formwork it is first it is sliding will slowly into
Row, and in the process, to hydraulic device, 13 structure of template and related facility, in load conditions, comprehensive system inspection,
It finds the problem, handles in time, can be carried out after all going well normal sliding.When construction is transferred to normal sliding, it should keep as far as possible
It works continuously, demoulding concrete surface quality is observed by special messenger, with the suitable sliding time of determination and sliding speed.Normal day is sliding
4-6m or so is risen, this needs is determined according to compbined tests such as concrete property, feeding strength, environment temperature, demoulding strengths.
Concrete should be done before concreting and consolidates body setting test, should control it solid body setting time 4~6 hours.To protect
Card concrete smoothly puts in storage, it is desirable that concrete workability, good fluidity, the slump meet pumping requirements.The concrete surface of demoulding
Trowel troweling should can be used by having hard feeling and the finger mark of 1mm or so can be extruded without trickling and drawing crack phenomenon, hand.If demoulding is mixed
Solidifying soil face is smooth, can not do troweling processing.If demoulding concrete face is defective, concrete surface repairing should be carried out immediately, generally
It is flattened in concrete surface with magma with trowel.In order to which sliding formwork can be gone on smoothly, concrete supply is continuous.When concrete initial set
Between requirement to choose the Fresh Concrete with Admixtures presetting period and climate temperature etc. can be adjusted in time depending on the site environment.
The maintenance of concrete defect elimination: magma reparation is carried out to concrete using bracket panel 15 in time after demoulding, it is desirable that light,
It is even, smooth.To make demoulding concrete surface that there is suitable curing condition, prevents crack, be arranged on bracket panel 15
Curing agent can also be used in sprinkler pipe, is conserved in time to demoulding concrete face.
Die body decentralization, translation: after sliding formwork slides into design position, first by die body it is fixed using the suspention of roll bolt 12 or
Trolley 10 suspends pole-climbing in midair, installs jack 1；Or suspended in midair using guide chain, demoulding lead screw 18 is unclamped, keeps template 13 and concrete de-
From；Thereafter using console control jack die body is slowly transferred on the moving track of tunnel bottom plate or using jack,
The modes such as hoist engine 8 are transferred.It recycles that elevator is led or other power draw die body moving to next storehouse number, starts next storehouse
The construction of number concrete slip-form.
It is so round-trip in proper order, gradually complete tunnel side wall concrete lining construction.It, can for needing the tunnel of vault lining cutting
It is realized using vault trolley 10；For abutment wall transition, arc section etc., implement again after simply transformation can be carried out.
The above embodiments are only the preferred technical solution of the present invention, and are not construed as limitation of the invention, this hair
Bright protection scope should be with the technical solution of claim record, technical characteristic in the technical solution recorded including claim
Equivalents are protection scope.Equivalent replacement i.e. within this range is improved, also within protection scope of the present invention.
