Description
Technical field
The laboratory of the shield tunnel model such as subway involved in the present invention, water delivery, municipal works section of jurisdiction prepares mould applications,
Specifically related to a kind of tunnel model test shield duct piece prepares mould.
Background technology
With the continuous input of China's infrastructure project, many cities are built in progress subway construction, municipal works on a large scale
If.Further, since China's distribution of water resources is uneven, cause northern extreme dehydration, to alleviate this present situation, China has built largely
Project of South-to-North water diversion, accordingly, it would be desirable to build numerous water-conveyance tunnels.In order to ensure such engineering build it is reasonable, safety, it is necessary to
Carry out substantial amounts of theoretical calculation and laboratory simulation experiment.
For a long time, in the model test of the shield duct pieces such as subway, water delivery, municipal piping lane, lining segment model is made
Mould be one-piece casting, one-shot forming forms monoblock type section of jurisdiction.Laboratory simulation tunnel duct piece seam is recessed using cutting mostly
The form of groove is by section of jurisdiction weakening strength, with the intensity of remainder gypsum come the bolt connection between simulated field section of jurisdiction, so
The longitudinal pulling force that can not really reflect between bolt and their moment of flexure, cause experimental result and True Data to have larger difference
It is different.
The mould that existing laboratory prepares shield lining segment is mainly the mould being made using steel plate as material.Pouring
It is mainly during tunnel duct piece model and pours circlewise, the position spliced eventually through the mode of strength degradation in each section of jurisdiction is carried out
Groove is cut, with the intensity of remainder gypsum come the longitudinal bolt of the pipe sheet assembling of simulation tunnel.According to live actual prospecting feelings
The many concrete in bolt interface in destruction position of condition shield duct piece due to suffered pulling force by drawing crack, and above-mentioned experimental model
But the effect of simulation is unable to reach, pulling force can not also be directly obtained suffered by shield duct piece longitudinal bolt in practice in addition.
Term is explained
Shield duct piece：After tunnel excavation, it is necessary on the inside of tunnel lay one layer of lining cutting with reach supporting tunnel and
The function of water blockoff；
Model test：In research shield duct piece force-mechanism, typically it is difficult at the scene, it is therefore desirable to by certain contracting
Chi ratio prepares test model, and then research structure stress characteristic；
Segment die：Test model shield duct piece is prepared, it is general that cast in situs is carried out using gypsum, and needed when pouring
Want segment die.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of tunnel model test shield duct piece and prepare mould, laboratory
The sectional type shield duct piece being consistent with scene can be truly prepared, and then is reached and live section of jurisdiction identical structure stress feature.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of tunnel model test shield duct piece prepares mould, including is in turn connected to form the portion of binding of circle, first faces
Socket part, the first standard portion, the second standard portion, the 3rd standard portion and second are bordered by portion, and the portion of binding, first are bordered by portion, first
The mould that standard portion, the second standard portion, the 3rd standard portion and second portion of being bordered by are formed is overall structure；The structure in the portion of binding
For：Bind and be fixed with the block cover plate that binds on block；Described first is bordered by portion and the second structure for being bordered by portion is：It is bordered by being fixed with block
It is bordered by block cover plate；The structure in the first standard portion, the second standard portion and the 3rd standard portion is：Calibrated bolck is fixed with calibrated bolck
Cover plate；The portion of binding, first be bordered by portion, the first standard portion, the second standard portion, the 3rd standard portion and second be bordered by between portion it is solid
Surely there is dividing plate；The block that binds, the inner surface for being bordered by block and calibrated bolck formation mould, the block cover plate that binds, are bordered by block cover plate
With the outer surface and side of calibrated bolck cover plate formation mould；The block that binds, it is bordered by block, calibrated bolck, the block cover plate that binds, is bordered by
All it is provided with block cover plate, calibrated bolck cover plate and dividing plate between some bolts hole, two connected bolts hole and penetrates bent bolt.
Further, the external diameter that the tunnel model test shield duct piece prepares mould is 600mm, and internal diameter is 540mm.
Further, described first be bordered by portion and second be bordered by portion angle be 68 °, the first standard portion, second mark
The angle in quasi- portion and the 3rd standard portion is 67.5 °.
Further, the ring angle of the bolt hole is 22.5 °.
Further, the length of run of the block that binds is 101.32mm, and width is 150mm.
Further, the length of run of the calibrated bolck is 320.44mm, and width is 150mm.
Further, the length of run for being bordered by block is 318.09mm, and width is 150mm.
Further, 15mm*15mm square is cut with around the bolt hole, is easy to be removed when pouring.
Further, a diameter of 5mm of the bolt hole.
Compared with prior art, the beneficial effects of the invention are as follows：1) overcome conventional lining segment and be unable to piecemeal making, no
It can determine between lining segment, the shortcoming of ring and longitudinal reinforcement force-bearing situation；2) can accurate simulated field shield duct piece,
Of different sizes, completely identical in structure model can be made according to the model likelihood ratio；3) present invention is that the making likelihood ratio is 1:10
Lining segment make mould specific size, the mould of different proportion can be made according to the likelihood ratio, is so then conveniently entered
The making of the lining segment of row different proportion, to meet Laboratory Request；4) the shield model section of jurisdiction is not only applicable metro shield
Tunnel model test, meanwhile, apply also for water works, the modelling in the shield tunnel model test such as municipal administration.
