Description
Technical field
The present invention relates to liner structure prefabricated mould and applications, and in particular to multiple dimensioned lining cutting in a kind of tunnel model test
Structure prefabricated mould and construction method.
Background technique
During shaketalle test, tunnel surrounding, lining cutting, suspension roof support etc. are prepared by the determining model likelihood ratio, then
The earthquake response at existing tunnel scene.Therefore, inevitably need to prepare tunnel surrounding and the isostructural mold of lining cutting and technology
Method.In research in this regard, due to difference of tunnel cross-section shape, including the shape of a hoof, circle, rectangle etc., still
Circular cross section is relatively conventional one of section.For such problems, many researchers and scholar are inquired into,
For some by the wood mold coupled preparation for completing liner structure model test piece of quick Fabrication, method is simple, low in cost, but wooden
Mold chance water is easily-deformable, directly results in liner structure moulded dimension error, generates apparent dimensional effect；Some passes through steel circle
Ring sleeve and built-in multiple sphenoids form cylindrical body by controlling multiple steel sphenoids, form " ring set with steel cylinder
Although body structure ", this method overcome the easily-deformable problem of wood mold coupled rainwater, but mold can do at high cost, and operation is multiple
It is miscellaneous, and demould difficult；The transparent glass sleeve that directlys adopt also carries out the prefabricated of liner structure, simple and efficient, but transparent
Glass sleeve surface leads to liner structure surface irregularity etc. since the acid-base property of similar model material generates scratch later,
It is poor for the applied and operability of layer during similar model test.
Summary of the invention
Goal of the invention: the object of the present invention is to provide liner structure prefabricated mould multiple dimensioned in a kind of tunnel model test and
Construction method solves difficult, the complicated for operation problem of existing mold demoulding.
Technical solution: multiple dimensioned liner structure prefabricated mould in tunnel model test of the present invention, including the first knot
Structure main body and the second main structure body, second main structure body are nested in the first structure main body, the first structure master
Body is made of dismountable two semi-cylindrical in configuration bodies, and second main structure body is cylindrical structure, the semi-cylindrical in configuration body
On be provided with demolding structure and means for mounting coupling parts, the demolding structure include be arranged in semi-cylindrical in configuration body two sides demoulding ladder slot and
The demoulding block being connect with demoulding groove.
Wherein, described two semi-cylindrical in configuration bodies are linked together by means for mounting coupling parts.
The means for mounting coupling parts includes boss and the groove that is adapted to boss.
Second main structure body is transparent cylinder structure.
The construction method of multiple dimensioned liner structure prefabricated mould in tunnel model test of the present invention, including following step
It is rapid:
(a) wall in semi-cylindrical in configuration body is uniformly smeared into machine oil using hairbrush；
(b) two semi-cylindrical in configuration bodies are combined according to boss and the one-to-one mode of groove, are placed on vertically
On experimental bench or on smooth glass plate；
(c) the second main structure body is nested into first structure main body, forms ring set ring structure；
(d) steel ruler or the center of micrometer alignment first structure main body and the second main structure body are utilized；
(e) prepared liner structure analog material solution is poured into ring set ring structure, after material reaches early strength,
Fixed first structure body side semi-cylindrical in configuration slides out other side semi-cylindrical in configuration using terraced slot is demoulded, so straight up
Remove the liner structure that fixed semi-cylindrical in configuration prepares to get road in succession afterwards.
It is quick and precisely positioned the utility model has the advantages that the present invention can satisfy liner structure test specimen in physically scaled model test, side
Just it demoulds, solves the problems, such as that multiple dimensioned liner structure is prefabricated, avoid the bias occurred in liner structure preparation process and thickness problem,
Test can either be saved and process the time of punching block in the process, and a large amount of test processing charges, acceleration model test can be saved
Efficiently carry out.

Specific embodiment
Invention is further explained with reference to the accompanying drawing.
As shown in Figs. 1-5, multiple dimensioned liner structure prefabricated mould in tunnel model test, by first structure main body 1 and embedding
It covers and is constituted in intracorporal second main structure body 10 of first structure master, first structure main body 1 is removably mounted at together by two
Semi-cylindrical in configuration body composition, semi-cylindrical in configuration body include demolding structure and means for mounting coupling parts, and demolding structure includes demoulding block 2, takes off
Mould groove 3 and terraced slot 4 is demoulded, it is highly 50mm that demoulding block 2, which is located at the both ends of semi-cylindrical in configuration main body, outer diameter 140mm, interior
Diameter 120mm, demoulding block 2 are connect by demoulding terraced slot 4 with demoulding groove 3, demould terraced slot 4 perpendicular to demoulding block 2 and demoulding
3 direction of groove, demoulding 3 height of groove are 50mm, outer diameter 130mm, internal diameter 120mm.
Means for mounting coupling parts includes boss 6 and groove 7,1 internal diameter 1.5mm of means for mounting coupling parts range semicircle rod structure main body, semicolumn
Boss 6 is arranged in structural body side, and groove 7 is arranged in the other side, and when two semi-cylindrical in configuration bodies assemble, boss 6 and groove 7 are suitable
Match, boss 6 is mounted in groove 7, and boss 6 is rectangular blocks, and groove 7 is and 6 respective slot structure of boss.Second main structure body
10 be transparent cylinder shape structure.
In using the present invention, wall in semi-cylindrical in configuration body is uniformly smeared into machine oil using hairbrush；By two semicolumn knots
Structure body is combined according to boss 6 and the one-to-one mode of groove 7, be placed on experimental bench vertically or smooth glass plate on；
Second main structure body 10 nests into first structure main body, forms " ring set ring " structure；Using steel ruler or micrometer to the first knot
The center of structure main body and the second main structure body, specifically: (in the second selected main structure body 10 of the internal diameter-of first structure main body 1
Diameter) ÷ 2, the second main structure body outside diameter wall as a result as selected to the measurement distance between 1 inner diameter wall of first structure main body；It will
Prepared liner structure analog material solution pours into " ring set ring " structure and fixes the first knot after material reaches early strength
The semi-cylindrical in configuration of structure body side slides out other side semi-cylindrical in configuration using terraced slot 3 is demoulded straight up, then moves in succession
Except fixed semi-cylindrical in configuration；The liner structure prepared is put into curing box to conserve, until laboratory prescribed strength is laggard
The test of row physically scaled model；After demoulding, first structure main body is cleared up, and repeats above step, carries out next group
The preparation of lining cutting sample.
