Description
Technical field
It the utility model is related to large cross-section tunnel and excavate periphery hole fast positioning mould, applied to the tunnel in constructing tunnel
Excavate periphery hole positioning.
Background technology
In constructing tunnel, because the narrow procedure connection of construction surface is extremely important, in order to save the time, tunnel excavation periphery hole
It must quickly be accurately positioned, out break occur if inaccurate, increase construction cost also influences construction speed, if single
In order to accurate positioning then the setting-out time it is oversize also influence construction speed, at present in tunnel tunnel face setting-out mainly using traditional
Five inch station method and coordinate method, but operation process speed is very slow, also there is the big gun built in using instruments such as total powerstation or laser cross section instruments
Eye Setting-out procedures positioned, but due on face ride comfort it is poor, cause positioning precision low.
Utility model content
The utility model is to avoid the deficiency present in above-mentioned prior art, there is provided a kind of large cross-section tunnel excavates periphery
It is sharp-eyed fast jig, large cross-section tunnel is excavated periphery hole and obtain quick accurate positioning, to improve efficiency of construction, ensure
Construction quality.
The utility model adopts the following technical scheme that to solve technical problem：
The utility model large cross-section tunnel excavates being structurally characterized in that for periphery hole fast positioning mould：Three lists of subsection setup
First mould, and by three unit moulds through assembly be sequentially connected composition semiarch mould, two groups of semiarch moulds top phase spell shape into
Vault, the bottom of two groups of semiarch moulds is propped up respectively stands in both sides arch springing position, by the spacing of setting on three unit moulds
The eyelet of insertion is provided with, forms periphery hole arched mold.
The design feature that the utility model large cross-section tunnel excavates periphery hole fast positioning mould is lain also in：Three lists
The die width of first mould is 6cm, thickness 5cm, forms overlap joint with the step surface of mutual cooperation between adjacent cells mould, takes
Spreading degree is 10cm.
The design feature that the utility model large cross-section tunnel excavates periphery hole fast positioning mould is lain also in：Three lists
A diameter of 2cm of eyelet on first mould.
The design feature that the utility model large cross-section tunnel excavates periphery hole fast positioning mould is lain also in：Three lists
First mould is using high intensity, lightweight plastic plate as material.
Compared with the prior art, the utility model has the beneficial effect that：
1st, the utility model uses mould direct setting-out at the scene, and polyvinyl chloride, accurate positioning, using effect is splendid, has
Effect improves efficiency of construction, and ensures construction quality.
2nd, the utility model in actual applications, by adjusting the radian and size of three unit moulds, is applicable to appoint
The positioning operation of the tunnel perimeter eye of what section type.

Embodiment
Large cross-section tunnel excavates periphery hole fast positioning mould in the present embodiment, it is characterized in that：Three units of subsection setup
Mould, and three unit moulds are sequentially connected composition semiarch mould through assembly, two groups of semiarch moulds are in top phase spell shape arching
Top, the bottom of two groups of semiarch moulds is propped up respectively stands in both sides arch springing position, is set on three unit moulds by the spacing of setting
The eyelet of insertion is equipped with, forms periphery hole arched mold；The die width of three unit moulds is 6cm, thickness 5cm, adjacent list
Overlap joint, lap of splice 10cm are formed with the step surface of mutual cooperation between first mould；Eyelet on three unit moulds it is straight
Footpath is 2cm；Three unit moulds are using high intensity, lightweight plastic plate as material.
In specific implementation, as shown in figure 1, three units are from bottom to top followed successively by the list of first module 1, second in semiarch mould
Member 2 and third unit 3, three units press each position arching, and set eyelet 4 by the blasthole spacing of setting.
Shown in Fig. 2 a and Fig. 2 b, the lap segment of first module 1 is arranged on top, and through hole 5 is provided with lap segment, for
The phase of second unit 2 is spliced, and the spacing for setting two eyelets in bottom in first module is 30cm, and the spacing of other each adjacent eyelets is
50cm。
Shown in Fig. 3 a and Fig. 3 b, the lap segment of second unit 2 is arranged on upper and lower ends, is all provided with the lap segment of upper and lower ends
It is equipped with through hole 5, the upper and lower ends lap segment in second unit 2 is respectively used to mutually splice with third unit 3 and first module 1,
The interval for setting each adjacent eyelet in second unit 2 is 50cm；
Shown in Fig. 4 a and Fig. 4 b, the lap segment of third unit 3 is arranged on bottom, and through hole 5 is again provided with lap segment, uses
In with mutually splice in second unit 2, the spacing for setting two eyelets for being in top in third unit is 59cm, other each phases
The spacing of adjacent eyelet is 50cm.
In Specific construction, as shown in figure 1, four anchor points are gone out using total powerstation setting-out according to explosion design drawing first,
It is respectively：First module mold bottom anchor point P1, first module mould and second unit mould stitching portion anchor point P2, second
Unit mould and third unit mould stitching portion anchor point P3, and third unit die tip anchor point P4；In each anchor point
Place's implantation φ 18 reinforcing bars are used to fix three unit moulds, and the protruded length of reinforcing bar is not less than 20cm, to avoid because of face not
It is smooth to cause mould not laid；Segmentation installation each unit mould, recycling penetrate rifle and pass through the eyelet thenad on each unit mould
Nailing is injected in sub- face, and nailing should carry color, and to check, nailing position is periphery hole trip-out position；Position periphery hole eye
Position sectional is carried out, and can also unify positioning after integral installation again, same method can fast positioning go out half side periphery hole in addition and pull out of hole
Position.
Inventive die can quickly, be accurately positioned out Tunnel Blasting construction in periphery hole position so that after Tunnel Blasting
Excavation face is smooth, smooth-going, and out break is more preferably controlled, and improves efficiency of construction.
The utility model is applied to Beijing-Shanghai high speed Jinan connecting line project pulp-water spring Smooth Blasting at Changle Tunnel, and effect shows
Write.
