Description
Technical field
The utility model relates to the experimental provision of compression of a kind of overlying strata separation layer district's filling slurry and Penetration Signature, is particularly useful for compression of absciss layer district filling slurry and Penetration Signature experiment are used.
Background technology
According to national coal mine under the unified-allocation system incomplete statistics in 1993, China's " three times " (being under the buildings, under the water body, under the railway) pressed coal nearly 137.64 hundred million t, wherein 94.68 hundred million t under the buildings.Along with the exhaustion day by day of coal resources, the many mining areas of China all are faced with the problem of exploitation coal mining under buildings; In addition, the exploitation of underground coal also causes subsidence, and causing the farmland to be destroyed can't cultivate.How to liberate buildings and press down coal, reduce and the control land subsidence, the protection mining area ecological environment has become the current problem that presses for solution.Overlying strata separation layer district grouting filling subtracts the appearance of heavy technology, for the solution of the problems referred to above has brought new hope.From this technology in 1985 be introduced into domestic since, Fushun, Da Tun, Yanzhou, open mining areas such as Luan, Xin Wen, Zaozhuang, Nan Tong, Huainan and all carried out the enforcement of this technology, and obtained certain effect.Yet because the complicacy of depositing is composed on the stratum, for the grouting filling slurry in the absciss layer district, it under the double action of reservoir pressure and grouting pressure with which kind of form exist, the compression of slurry and Penetration Signature be how in the absciss layer district, and existing which kind of relation or the like between the water cut of down-hole water yield and filling slurry again, all similar problem all are not resolved by a kind of effective means so far.Therefore need a kind of analogue experiment installation that the problems referred to above are studied, for the engineering practice at scene is provided fundamental basis and experimental basis.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, the overlying strata separation layer district filling slurry compression that precision is high and the experimental provision of Penetration Signature.
For achieving the above object, the utility model comprises and is located at the water conservancy diversion base plate on the bearing plate under the pressure experiment machine, the lower side of water conservancy diversion base plate is provided with jigger, the surface of water conservancy diversion base plate is provided with a plurality of guiding gutters, and be provided with the metal sleeve of the filling sample that covers on a plurality of guiding gutters, the bottom of metal sleeve is provided with the pervious concrete plate that places on the guiding gutter, and the top of metal sleeve is provided with the cover plate that is pressed on the sample, and the top of cover plate is provided with bearing plate.
Described pervious concrete plate, cover plate are in the face of being equipped with O-ring seal between sample one end and the metal sleeve inwall.
Beneficial effect: the utility model utilizes the absciss layer space of metal sleeve simulation overlying strata, and adopt the pervious concrete template die to intend the rock stratum up and down of overlying strata separation layer, by pressure testing machine the filling slurry in the metal sleeve is pressurizeed, simulate the filling slurry truly and in the absciss layer space, had environment and a state, can Accurate Analysis filling slurry compression and the Penetration Signature under the different loads effect; Simultaneously by changing the water permeability of pervious concrete plate, compression and the Penetration Signature that also can test different lithology condition retrofilling slurry; The water conservancy diversion backplate surface is provided with guiding gutter, the water of seepage flow in the slurry stand under load process can be accumulated in the measuring cup, thereby can study getting in touch between water yield and the filling slurry water cut easily; Simple in structure, the measuring accuracy height, reliable and stable, and safe.
