Abstract
The invention discloses a device for manufacturing a surrounding rock similar material building block of a high ground temperature roadway. The device comprises a base, wherein a plurality of concentric annulus protecting plates of which the heights are the same and the diameters are different are arranged on the base; a plurality of iron plates are alternatively arranged among the concentric annulus protecting plates at intervals; clamping grooves connected with the concentric annulus protecting plates are formed in the base. The device is used for manufacturing the surrounding rock similar material building block of the high ground temperature roadway, the prefabricated building block has sufficient time to maintain, is relatively stable in thermal physical property and can ensure the homogeneity and the isotropy of simulation surrounding rock, the manufactured building block can be directly mounted inside an experiment well cylinder, the thermal stress generated in the heating process can be alleviated because of a material cast into cracks among building blocks, and thus equipment is prevented from being damaged by thermal expansion of the material of the building block.
Description
Technical field
The present invention 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: object of the present invention, 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 invention 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 invention 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, apparatus of the present invention 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, one embodiment of the present of invention are further described:
As shown in Figure 1, High-geotemperature roadway surrounding rock analog material producing device of the present invention 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.
The preparation process of the country rock analog material building block in High-geotemperature of the present invention tunnel:
A, first the foreign material on base 1, annulus backplate 2 are cleaned out;
B, use double-screw bolt and nut 6 and fixed head 5 are by the annulus backplate joint forming of diameter maximum;
C, multiple donut backplates 2 are fitted together by the draw-in groove 3 on base 1;
D, on each donut backplate 2 inwalls and base 1, brush vegetable oil;
In the ring groove of e, formation between multiple donut backplates 2, pour the simulation High-geotemperature roadway surrounding rock analog material mixing into;
F, device is put on bumper, fully close material;
In g, the space that forms between every two annulus backplates, staggered interval arranges iron plate 4, at interval of 60 °, an iron plate 4 is set;
E, after 24 hours, take off fixed building block, complete the preparation of country rock analog material building block.
