Description
Technical field
The invention belongs to build work field, it is related to a kind of local penetration tunnel-liner and pours die trial, can be used for pouring different examinations
The local penetration tunnel-liner of part thickness and different height of specimen.
Background technology
There is scholar to point out 10 years following, China will build 20,000 kilometers of all kinds of tunnels, including vcehicular tunnel, high ferro tunnel, water
The forms such as sharp tunnel, city underground.In order to mitigate the water pressure that tunnel is born, penetrating passage is often reserved, adds lining cutting tunnel
The Lining Crack that the assembled seam in road and long-term operation generate, all so that tunnel-liner is there are certain permeability, but tunnel
The case where lining cutting different parts fracture number in road differs, this each position for allowing for tunnel will appear different permeability.Has section
It learns and tunnel-liner is often reduced to equivalent pervious bed in research, but be difficult to realize in experiment, therefore the research of this respect
It focuses mostly in analysis research and numerically modeling.Lose the support of test data, theoretical research at will have a greatly reduced quality, therefore in order to
Overcome existing for existing research means insufficient, supplement the experimental data of Related Research Domain, the present invention has developed a kind of part and oozes
Saturating tunnel-liner pours die trial.
Invention content
In order to overcome the shortcomings of in existing tunnel research, the present invention provides local penetration tunnel-liners to pour die trial, energy

The technical solution adopted by the present invention to solve the technical problems is：A kind of local penetration tunnel-liner pours die trial,
The device includes four die trial pedestal, die trial outer cover, die trial liner and separate sheet parts；It is carved with if the die trial pedestal is one piece
The round iron plate of the concentric toroidal cavity in arterial highway；The die trial outer cover includes outside bottom outer cover, index bed outer cover and top layer
Cover；The bottom outer cover is two pieces of 180 ° of consistent curved plate A, and the tops curved plate A vehicle has external corner step A, internal vehicle to have
Groove A is detached, curved plate A is welded with ear A and handle A；The index bed outer cover is two pieces of 180 ° of consistent curved plate B,
Vehicle has an external corner step B at the top of curved plate B, and internal vehicle has a separation groove B, and bottom vehicle has inner corner trim step B, curved plate B to be welded with
Ear B and handle B；The top layer outer cover is two pieces of 180 ° of consistent curved plate C, and the bottoms curved plate C vehicle has inner corner trim step
C, internal vehicle have separation groove C, curved plate C to be welded with ear C and handle C；The die trial liner is an elongated hollow cylinder,
External vehicle, which has, detaches groove D, and welding drum handle on hollow cylinder facilitates carrying；The separation groove A, it detaches groove B and divides
Up and down from groove C；The separation groove A, separation groove B, separation groove C and the width and separate sheet thickness that detach groove D
Degree is consistent, for placing separate sheet；The interior outer radius and bottom outer cover of toroidal cavity on the die trial pedestal and hollow
The size of cylinder is consistent, in order to assemble；The hollow cylinder and bottom outer cover are respectively embedded into the different circular ring shape of die trial pedestal
In groove, to obtain the hollow cylindrical mortar specimen of different size.
Further, the inner corner trim step B depth one in the external corner step A height and index bed outer cover on the bottom outer cover
It causes, the interior outer radius of the two is consistent；Inner corner trim step C on external corner step B height and top layer outer cover on the index bed outer cover
Depth it is consistent, the interior outer radius of the two is consistent；To ensure to contact close, gap of not boxing out, it is ensured that pour between different outer covers
Specimen Shape out is the hollow cylindrical of standard.
Further, the height of the external corner step B of the index bed outer cover is consistent with inner corner trim step B depth, passes through increase and decrease
The number of plies of index bed outer cover controls the height of test specimen.
Further, the ear A, ear B, there are two tapping thread holes on ear C, respectively will using screw and nut
Two ear A, two ear B, two ear C are tightened, so that two pieces of consistent curved plate A, curved plate B, arcs
Steel plate C can be fitted closely from each other.
The beneficial effects of the invention are as follows：
1, present invention introduces separate sheets the hollow cylinder space between die trial outer cover and die trial liner is divided into it is multiple
Mutual independent space, the mortar by pouring different ratio in each separate space can obtain local penetration tunnel lining
It builds, and can be by adjusting the position of bottom outer cover and hollow cylinder on die trial pedestal to obtain the sand of different-thickness
Test specimen is starched, different tests demand is met.
2, present invention introduces index bed outer covers, on the one hand can accomplish placement layer by layer, help to ensure that pouring quality, another
Aspect can adjust the height in tunnel by adjusting the number of plies of index bed outer cover.
3, multiple tracks concentric grooves are carved on die trial pedestal of the invention, not only play fixed die trial liner and die trial outer cover
Effect, and disclosure satisfy that needed for different tests, it is cost-effective.
4, die trial outer cover of the present invention is two pieces of 180 ° of consistent curved plates, and is welded with handle, carrying and form removal side
Just, and influence of the form removal to test specimen can be reduced.
