Description
Technical field
The present invention relates to a kind of organic glass molds for making compound section tunnel-liner model, can be used particularly for making
Various sizes of list hole tunnel, multiple-arch tunnel and other compound section tunnel-liner models.
Background technique
The design and construction theory of for example asymmetric multiple-arch tunnel in compound section tunnel is sufficiently complex.Model test is to solve this
Class problem provides method the most intuitive, the especially stress characteristic of research compound section tunnel lining structure and destroys mould
Formula.In related tunnel model test, it is ensured that the integrality of tunnel structure and its consistency with prototype serve as a contrast tunnel
The production of block is particularly difficult.And to meet water easily-deformable for existing plank mold, is not easy to reuse, the model of production is coarse；It is whole
Formula steel die cost is higher, and weight is big, and demoulding is complicated and success rate is lower；The model of hot rolling type organic glass Mold Making is disconnected
Face is uneven.
Summary of the invention
In order to overcome existing plank mold to be not easy to reuse and accurate forming, Integral Steel molding jig cost is high, again
Amount is big and demoulding success rate is low, and the model section of hot rolling type organic glass Mold Making is uneven, and the present invention provides a kind of production
The pin-connected panel organic glass mold of compound section tunnel-liner model, the mold can not only accurately make various sizes of list
Hole tunnel, multiple-arch tunnel and other compound section tunnel-liner models are particularly suitable for the biggish complicated tunnel of production scale bar
Lining model, and cost is relatively low, handling ease, demoulding is convenient, high at mould rate, the tunnel-liner model globality after pouring compared with
It is good.
The technical scheme adopted by the invention is that:
A kind of organic glass mold making compound section tunnel-liner model, comprising: organic glass pedestal 3, organic glass
Glass external mold 5, one or more organic glass internal models 7,
The organic glass external mold 5 is made of muti-piece with the bent wall column exterior sheathing of outer handle 4 closed
Cylindrical body has splicing seams 9 between adjacent two blocks of exterior sheathings；
The organic glass internal model 7 is made of muti-piece with the bent wall column inner template of internal handle 6 closed

0.5mm is reduced than unified, the outer arc radius of external mold slot 1 is unified compared with the side dimension of organic glass external mold 5 to be increased
0.5mm, it is therefore an objective to guarantee to facilitate while tunnel-liner model accuracy organic glass internal model 7, organic glass external mold 5 insertion with
It extracts.
On the basis of above scheme, the organic glass internal model 7 and organic glass external mold 5 will be divided in processing
Block, cut-off rule correspond to the intersection point of different radii camber line, every block of exterior sheathing, inner template by multiple well cuttings with a thickness of 15~
The organic glass item of 30mm is bonded with strengthened water proof glue, facilitates processing and assembling, the organic glass mold is transparent
, convenient for having seen whether bubble when pouring lining model material.
On the basis of above scheme, the outer handle 4 is plexiglass block, is pasted in the outside of exterior sheathing, inside
Handle 6 is plexiglass block, is pasted in the inside of inner template, and the size of outer handle 4 and internal handle 6 can be according to organic glass
The size of mold is adjusted accordingly, the minimum 20mm of the width of outer handle 4, the minimum 15mm of the width of internal handle 6,
Outer handle 4, internal handle 6 divide equally upper and lower two rows of, upper array pitch die head 4cm, lower array pitch template bottom 6cm, design idea
For convenience of demoulding.
On the basis of above scheme, the position of the splicing seams 9 will guarantee vertical, and the slit width of splicing seams 9 is no more than
1mm must use adhesive tape tight closure at the position of splicing seams 9, and slurries leak from splicing seams 9 when preventing from pouring lining model material
Out.
On the basis of above scheme, the clamp 10 is used to guarantee that tunnel-liner model to pour the thickness symbol at 8 top of slot
Design size is closed, the organic glass mold of each production compound section tunnel-liner model generally requires 4~10 clamps 10.
On the basis of above scheme, the outer surface of the organic glass internal model 7, the inner surface of organic glass external mold 5 are applied
Certain thickness vaseline is smeared, every block of exterior sheathing, the contact site of inner template and organic glass pedestal 3, tunnel-liner model pour
It builds the bottom end of slot 8, smear a small amount of vaseline at splicing seams 9, for convenience of demoulding.
On the basis of above scheme, in the outside of the organic glass pedestal 3 and organic glass external mold 5, organic glass
The contact position of the inside of mould 7 is closed with soft higher fatty acids soap (soap), slurries when preventing from pouring lining model material
It is leaked out from organic glass pedestal 3, the effect for preventing slurries from leaking is preferable.
The invention has the advantages that various sizes of compound section tunnel-liner model can be made, and structure letter
Single, accurate positioning, it is convenient to operate, and cost is lower, reusable, and demoulding is convenient, high at mould rate, good integrity.
