Degree.At present following steps are roughly divided into during constructing tunnel：Prepare before construction；Tunnel portal section is constructed；Environmental monitoring
Measurement；Tunnel advanced support；Tunnel trunk excavates；Inverted arch excavation supporting；Tunnel inner waterproofing draining.Wherein inverted arch excavation supporting needs
Bow member is installed and concrete is poured into a mould into camber and is connected cast with top bow member, while also wants the related concrete by abutment wall
Pour into a mould together, the concrete of the concrete that top two serves as a contrast and bottom inverted arch is formed ring entirety, then second pouring backfill coagulation
Soil, fill concrete label is lower, to strengthen the bearing capacity of inverted arch concrete, reaches design requirement standard.Current
In constructing tunnel, the construction method generally used is the concrete of the lining of cast two after the concrete for first pouring into a mould bottom cyclization, but by
Use, waited so concrete is hardly formed ring camber, during practice of construction after concrete initial set by applying in lacking arc formwork
Worker person could be made concrete form camber reluctantly, then could be poured into a mould the concrete of abutment wall, cause coagulation soil application with spade
The time of work is grown, low construction efficiency, also greatly adds the labor intensity of workmen, and constructing tunnel is badly in need of a kind of tunnel at present
Road abutment wall inverted arch concrete cyclization cast full arc template.
The content of the invention
The purpose of this utility model is to overcome current tunnel side wall inverted arch cyclization construction due to lacking arc formwork, so mixed
Solidifying soil is hardly formed the technical problem of ring camber, is automatically moved so as to disclose a kind of tunnel side wall inverted arch concrete cyclization cast
Full arc template.
The utility model is achieved through the following technical solutions：
Planar arc inverted arch template is interconnected to form by every three to five pieces of plane templates in side or using integral mold plate as plane
Arc inverted arch template, be hinged sidewall template respectively in the inverted arch template end of both sides, in arc inverted arch template upper level direction
Be connected with each other by three to five tie-beams, wherein the tie-beam bottom at every interval be vertically arranged respectively three root posts by its with
Inverted arch template is connected with each other, while one root post of each setting is distinguished in tie-beam top both sides, solid respectively in two root posts upper end
Determine transverse beam, be inserted in telescoping tube in the hollow at transverse beam both ends respectively, hoist cylinder is fixed in telescoping tube outer end, and hoist cylinder is stretched
Road wheel is fixed at contracting end, and road wheel may pass through the note concrete mouth being correspondingly arranged in inverted arch template, two telescoping tubes and sidewall template it
Between respectively be hinged reinforce leading screw, be hinged demoulding oil jar respectively between the tie-beam both ends at remaining interval and sidewall template, at two
Longitudinal beam is fixed on tie-beam on the outside of column respectively to be connected with each other whole tie-beams, the fixed control on the tie-beam at edge
Case, control cabinet both sides installation reductor.
Tunnel side wall inverted arch concrete cyclization cast automatic moving full arc template provided by the utility model, overcomes at present
Various defects existing for similar construction, constructing tunnel is filled up and has been badly in need of a kind of tunnel side wall inverted arch concrete cyclization cast full arc mould
The blank of plate.Mutual hinge between sidewall template and inverted arch camber template is characterized in, device during installation is adjusted in full arc template,
Liftable is free, positions fast accurate, is convenient in demoulding, and walking is stable, easy to operate, can be effectively by cyclic concrete with filling out
Concrete step-by-step construction is filled, ensure that construction quality, improves efficiency of construction.
Brief description of the drawings
Accompanying drawing 1 is main structure diagram of the present utility model.
Accompanying drawing 2 is overlooking the structure diagram of the present utility model.
Reference title is as follows：Sidewall template 1, inverted arch template 2, hoist cylinder 3, telescoping tube 4, telescopic oil cylinder 5, walking
Wheel 6, tie-beam 7, demoulding oil jar 8, leading screw 9 is reinforced, transverse beam 10, longitudinal beam 11, note concrete mouth 12, column 13, control cabinet 14, is subtracted
Fast machine 15.
Embodiment：
The utility model is described in more detail below in conjunction with accompanying drawing：
Using integral mold plate as planar arc inverted arch template 2, in the end of inverted arch template 2 of both sides hinge sidewall template 1 respectively,
It is connected with each other in the upper level direction of arc inverted arch template 2 by five tie-beams 7, wherein the bottom of tie-beam 7 at every interval
It is respectively perpendicular and sets three root posts 13 to be connected with each other itself and inverted arch template 2, while distinguishes each setting in the top both sides of tie-beam 7
One root post 13, fixed lateral beam 10 is distinguished in the upper end of two root posts 13, is inserted in respectively in the hollow at the both ends of transverse beam 10 flexible
