Abstract
The utility model relates to an in-situ experimental device in a refuse dump in a strip mine. The device comprises a rectangular groove excavated in the refuse dump in the strip mine, wherein an independent rock body test sample is formed in the middle. Anchor rods fixed in the refuse dump in the strip mine are symmetrically arranged on both sides of the middle part of the rectangular groove. A steel I-beam is fixedly arranged on the top of each anchor rod. A jack I for applying horizontal shear force to the rock body sample is arranged on the lower part on one side inside the rectangular groove. A jack II which appllies pressure vertically is arranged on the top face of the rock body sample. The base of the jack II is fixedly arranged on the steel I-beam. The pushing pressure head of the jack II leans against the rock body sample. In-situ experiments in different vertical load conditions can be accurately performed to accurately determine the shear force and displacement and provide experimental basic data for rock property analysis so as to obtain relatively real in-situ experimental data of the original stratum. The device is compact in structure, convenient to operate, good in effect, low in cost and wide in application range.
Description
Technical field
The utility model relates to a kind of original position experimental provision, especially a kind of experimental provision that is applicable to refuse dump original position in surface mine.
Background technology
The original position experiment is widely used in multiple Geotechnical Engineering as a kind of important ground physical and mechanical experiment, obtains by experiment the physical strength parameter of ground, can play good effect for conceptual design and site operation.Because refuse dump in surface mine is to dump after being stripped from by the coverture more than the coal seam to form, its compaction rate is inhomogeneous, and the same layer position mixes by the overburden of different lithology, and structure is comparatively complicated.When in the ore deposit, the original position experiment is carried out in the refuse dump, can't effectively realize the load of Plumb load different stage in the open; Simultaneously due to interior refuse dump springy texture, lifting jack is in the process of pushing, therefore both sides lack supporter and very easily embed in the soil body,, be necessary existing original position experimental program is reasonably improved, so that a kind of original position experimental provision that is suitable for refuse dump in surface mine to be provided.
Summary of the invention
The purpose of this utility model is the problem that exists for prior art, and refuse dump original position experimental provision in a kind of simple in structure, easy to operate, effective surface mine is provided.
For achieving the above object, refuse dump original position experimental provision in surface mine of the present utility model, be included in the rectangular recess that forms independent rock mass sample in the middle of excavating on the refuse dump in surface mine, the middle part symmetria bilateralis of rectangular recess is provided with and is fixed on the anchor pole in the refuse dump in surface mine, and the top of anchor pole is fixed with steel I-beam; In described rectangular recess, a side lower part is provided with the I lifting jack that the rock mass sample is applied horizontal shear force, the end face of described rock mass sample is provided with the II lifting jack of exerting pressure along vertical, the base of II lifting jack is fixed on steel I-beam, and II lifting jack push head leans on the rock mass sample.
The base of described I lifting jack is provided with and is fixed on the inboard pressure-bearing steel plate of rectangular recess, and the push head of I lifting jack is provided with the shearing steel plate that leans against on the rock mass sample; The described II lifting jack push head end that leans on the rock mass sample is provided with the steel plate of exerting pressure.
Beneficial effect: the utility model can carry out the original position experiment under different vertical loading conditions accurately, can Accurate Determining shearing force and displacement, for the rock and soil properties analysis provides the experiment basis data, obtain the original position experimental data of comparatively real prime stratum, for geological state research and stability analysis provide basis and experimental basis, can carry out measuring to the shearing strength of prime stratum under the vertical load of difference.Its compact conformation, data are accurately, cost is lower, usable range is wide, have practicality widely.
