Visible multifunctional fracture seepage simulation test bench

Abstract

The invention relates to a visible multifunctional fracture seepage simulation test bench, which is applicable to simulation of seepage tests of fractured rock masses in geotechnical, geological, water conservancy, hydropower and other projects. A plurality of transverse, longitudinal and oblique water inlet and outlet fracture channels which are mutually communicated are formed on a bench top of the test bench, prefabricated fractured blocks are arranged in the fractured channels, fracture water-penetrating interfaces of all the fracture channels are respectively provided with water inlet and outlet pipes for constituting a circulation path with a water pump, flow sensors, pressure sensors and control valves are sequentially respectively arranged on the water inlet and outlet pipes, sand inlet ports are respectively arranged at inlets of all the water inlet pipes, and a sand adding funnel is arranged above each sand inlet port; and rubber seal pads are arranged on two sides of each fracture channel, and transparent cover plates are fixed on the rubber seal pads. The test bench can complete the measurement of test data required in the existing tests and effectively make up for the deficiencies of using rock samples for testing by observing the migration of fillers in fractures through an observation surface. The test bench has simple structure, convenient operation and good test effect.

Description

technical field [0001] The invention relates to a seepage simulation experimental bench, in particular to a visual multifunctional fracture seepage simulation experimental bench suitable for simulating the seepage of fractured rock mass in geotechnical, geological, water conservancy and hydropower projects. Background technique [0002] The seepage of fractured rock mass has an important influence on the safety of geotechnical engineering and water conservancy and hydropower engineering. Many scholars have done a lot of theoretical and experimental research on this. In practice, fractures often contain a certain amount of fillers. Although some scholars have studied the fractured rock mass containing fillers, because the rock mass used cannot observe the migration of fillers in the fractures, it can only pass Based on the analysis of experimental data and my own knowledge, we speculate the influence mechanism of filler on the permeability of fractured rock mass.

In actual situations, fissures often contain certain fillers. Although some scholars have conducted research on fissure rock masses containing fillers, because the rock mass used cannot observe the migration of fillers in the fissures, it can only be obtained through The analysis of the experimental data and my own understanding speculate the mechanism of the impact of the filler on the permeability of the fractured rock mass
