Problems solved by technology
The current seepage test device mainly has the following deficiencies: only one test block can be placed in the test device, and when multiple test blocks need to be tested, it takes too long and the efficiency is low; the test device cannot simulate the actual formation while applying lateral enclosure. Pressure and upper water pressure do not conform to the actual stress of damage and failure under the seepage action of grouting reinforced solid, which affects the accuracy of the test

Abstract
The invention relates to a multi-test block seepage testing device and a use method. The multi-test block seepage testing device comprises a pressure tank and a manual hydraulic pump, wherein the pressure tank communicates with a seepage testing main body device; the manual hydraulic pump communicates with the seepage testing main body device; the pressure tank is provided with three connectors and one pressure release valve; a first connector is connected with an air compressor for providing pressure for the pressure tank; a second connector is connected with a water pump for providing a water source for the pressure tank; a third connector is connected with a water tank arranged at the upper part of the seepage testing main body device and is used for providing a water source and pressure for the seepage testing main body device; the manual hydraulic pump is connected with an oil tank at the lower part of the seepage testing main body device and is used for providing lateral confining pressure for a test block. The invention further discloses a use method of the device. By adopting the device, damage of a grouting reinforcing body in a stratum under a lateral confining pressure condition and under the action of different seepage forces can be simulated, and seepage coefficients of the grouting reinforcing body under the action of seepage at different times can be also measured and calculated.
Description
technical field [0001] The invention relates to the field of seepage tests, in particular to a seepage test device with multiple test blocks capable of adding lateral confining pressure and upper hydraulic pressure and a use method thereof. Background technique [0002] As an effective method to deal with bad geology, grouting has achieved good treatment effect. Under the long-term seepage of groundwater, the fine particles in the grouted reinforced body will be taken away, thereby reducing the strength of the reinforced body and increasing the water permeability of the reinforced body. In order to simulate the damage and destruction of the reinforcement in the formation under the action of seepage, it is necessary to use a seepage test device for long-term seepage tests. The current seepage test device mainly has the following deficiencies: only one test block can be placed in the test device, and when multiple test blocks need to be tested, it takes too long and the effic...
