Description
Technical field
The present invention relates to the concrete linings such as Railway Tunnel, freeway tunnel, diversion tunnel, underground grottoes, culvert
Construction equipment technical field, more particularly, to a kind of lining construction for being adapted to radian size and changing within the specific limits
With the common template of telescoping steel form, the invention further relates to the installation and application of the common template.
Background technology
Telescoping steel form is to pour mode according to the difference of tunnel Internal periphery shape, tunnel lining concrete in constructing tunnel
Difference, a kind of special-purpose machinery construction equipment of tunnel liner building concrete is poured into a mould, has the advantages that cost is low, easy to use,
It is widely used in railway, highway, Construction for Hydroelectric Project.Construction interference can be not only avoided using formwork jumbo, is carried
High efficiency of construction, it is often more important that substantially increase the lining construction quality in tunnel, while also improve the machine of constructing tunnel
Tool degree.Although telescoping steel form pattern is more, structure is essentially identical, is all by template part, door frame body portion, Running System
System, supporting mechanism, translation system and other auxiliary equipments are formed.
Presently used telescoping steel form, its template piecemeal are substantially as follows：Along tunnel cross-section direction, using as shown in Figure 1
One group of arc formwork five piece（Or seven pieces one group）, this several pieces of templates are stitched together by the arc of tunnel cross-section, form and treat lining cutting
The consistent shape of tunnel Internal periphery；Along tunnel axis direction, single form length is 1.5~2.0 meters, along tunnel axis side
To setting 4~8 pieces of templates；Its sectional drawing and expanded view after installing is shown in Fig. 2, Fig. 3.Due to Railway Tunnel, highway tunnel
The radian of each engineering section such as road, diversion tunnel, underground grottoes, culvert is different from, so being required for making when constructing every time
A set of lining shuttering being adapted with required trimmed tunnel section radius could complete construction task.This cover die after the Practical Completion
Plate typically will act as scrap iron and dispose, and cause great waste, add the construction cost of individual works.
In order to reduce the cost of individual works, popular way is by manufacturing firm to old lining shuttering in the market
Further conversion after recovery.Main remodeling method be by original used old template, it is original using process reforms such as cutting, welding
The radian of template, to adapt to the requirement in the tunnel of next required lining cutting.This method, one to two can only be transformed to original template
Secondary, after transformation repeatedly, template just thoroughly loses its use value as lining shuttering；Make the mould transformed in this way
Plate quality is also not guaranteed.
In addition, certain methods are there has also been to adapt to a variety of different cross section lining concrete in tunnel constructions using a set of template,
Specific solution substantially has following two：
1st, arch template is changed under the premise of side template change is smaller or immovable.This method is applied to single-track railway
The lining cutting work in tunnel.Specific implementation method has two kinds：When after tunnel-liner changes of section, arch arc section template is complete
Portion changes, and retains side template, but so waste is still serious, does not tackle the problem at its root.Second, vault template is divided into
Two parts, after tunnel-liner changes of section, increase template between vault template two parts to realize reducing, arch template with
Using being articulated and connected between side template.The shortcomings that program is：1) the continuous reducing of lining shuttering can not, be realized；2), lining cutting
The difference amplitude of variation of cambered surface radius is small, can not typically be more than 40cm；3), single-track railway tunnel side wall lining amplitude is constant, only
Arch template is adjusted, is a kind of local method for changing radius；4) speed for, changing radius is slower；5), have to carry
The preceding short abutment wall of construction.
2nd, using standard combination steel form wide polylith 30cm or with cambered small template, in tunnel cross-section and axis two
The splicing extension of individual direction, and mast height is adjusted simultaneously and width carrys out trimmed tunnel.Use the wide standard combination steel of polylith 30cm
What template lining cutting different section radius tunnel utilized is the thought with Qu Daizhi.The shortcomings that this method is when the height of adjustment door frame
With, it is necessary to reinstall adjustment template, workload is big, and speed of application is slow, and the die parting line on lining cutting surface is more, not beautiful after width
See, and easily run mould.
