Abstract
The utility model discloses a similar surrounding rock material building block production device for a high geothermal roadway. The similar surrounding rock material building block production device comprises a base, wherein a plurality of concentric ring protective plates which are consistent in height and different in diameter are arranged on the base, a plurality of iron plates are alternately arranged among the concentric ring protective plates at intervals, and clamp slots connected with the concentric ring protective plates are formed in the base. The device is used for producing building blocks needed by round shafts in a physical similarity simulation test of the high geothermal roadway, the prefabricated building blocks can be maintained within enough time, and are relatively stable in thermophysical properties, and can guarantee the homogeneity and the isotropy of the simulated surrounding rock, the produced building blocks can be directly arranged in a testing shaft, materials poured in gaps formed among the building blocks can relieve thermal stress generated during heating process so as to prevent the thermal expansion of the building block material from damaging equipment.
Description
Technical field
The utility model relates to a kind of experimental provision, especially a kind of country rock analog material building block producing device that is applicable to make circular building block, is arranged on the High-geotemperature tunnel in circular wellbore model.
Background technology
In China, be accompanied by the increase to coal demand, the coal mining degree of depth is deepened year by year.Under the condition of deep mining, High-geotemperature becomes one affects underground labour's physical and mental health and the key factor of coal mining efficiency.The problem that solves High-geotemperature tunnel heat evil need to be carried out site test, and three kinds of modes of laboratory physical test and numerical simulation combine.In laboratory, design first the physical simulation test of High-geotemperature tunnel, in pilot system, adopt circular pit shaft.This just need to design supporting circular building block making apparatus to meet the making of pit shaft country rock material.
Summary of the invention
Technical matters: the purpose of this utility model, for the problem that building block that simulation test runs into is made being carried out in High-geotemperature tunnel in laboratory, provides the country rock analog material building block producing device in a kind of High-geotemperature tunnel.
Technical scheme: the country rock analog material building block producing device in High-geotemperature of the present utility model tunnel, comprise base, base is provided with the donut backplate that multiple height are consistent, diameter is different, between each donut backplate, alternate intervals has multiple iron plates, has the draw-in groove being connected with donut backplate on described base.
The donut backplate that described multiple height is consistent, diameter is different is 4-6, and the distance between donut backplate equates, the thickness setting that distance is required according to building block; Described donut backplate is by the bending butt welding of rectangle iron plate or be connected to form by double-screw bolt, nut and fixed head.
Beneficial effect: owing to having adopted technique scheme, device of the present utility model can be made for the required building block of the High-geotemperature tunnel physical simulation circular pit shaft of test.Prefabricated building block has sufficient time maintenance, and its thermophysical property is relatively stable, can ensure to simulate country rock homogeneous, isotropy, and the building block of made can be directly installed in experimental wwll cylinder.In addition, the utility model device can be in building block manufacturing process prefabricated crack, be applicable to simulate the test in crack.Be arranged on the material of building in the crack of the blockhouse formation in pit shaft and can alleviate the thermal stress producing in heating process, prevent material expansion damage equipment.

Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is further described:
As shown in Figure 1, High-geotemperature roadway surrounding rock analog material producing device of the present utility model is made up of base 1, multiple height is consistent, diameter is different donut backplate 2 and width is slightly less than two annulus backplate spacings, highly be slightly larger than the iron plate 4 of backplate height, on described base 1, have the draw-in groove 3 that is connected with annulus backplate 2, annulus backplate 2 connects by the corresponding draw-in groove on base 1.The donut backplate 2 that described multiple height is consistent, diameter is different is 4-6, and the distance between donut backplate 2 equates, the thickness setting that distance is required according to building block.The annulus backplate of diameter maximum is to be fixed plate 5 and to connect by being welded on the double-screw bolt 6 of its both sides by rectangle iron plate.
