Abstract

A multifunctional seepage deformation tester comprises a stander, wherein a vertical-loading and lateral-loading control system is arranged on an upper cover of a special combined-type seepage container which is made of organic glass, the special combined-type seepage container which is made of the organic glass and a vertical-loading and lateral-loading control system assembly is fixed on the stander, a water head measuring system, a flow-rate measuring system and a temperature measuring system are arranged on the side edge of the stander, and a water outlet pipe of a water head elevation device with an overflow pipe is connected with a water inlet valve on a base of the special combined-type seepage container which is made of the organic glass. The multifunctional seepage deformation tester has advantages that the requirements of universal parameter standard for soil test instruments can be met, and the multifunction of the test working condition and convenience and practicability in operation can be realized by researching a combined-type test container barrel. The cover weight loading is integrated with the lateral pressure loading, so that not only can the seepage characteristic parameters under no pressure be measured, but also the seepage characteristics of any underground point under the stress state can be simulated.

Description

technical field [0001] The invention relates to the technical field of rock soil and tailings measuring devices, in particular to a tester for measuring the permeability coefficient and seepage deformation parameter of soil or tailings with a particle size not greater than 5 mm under different boundary conditions. Background technique [0002] At present, there is no standard penetration deformation tester that has passed the technical appraisal in China. Only the "Soil Engineering Test Regulations" (SL237-1999) provides the test methods and test devices for the penetration and seepage deformation of coarse-grained soil, and each relevant scientific research institution makes its own test model to meet its specific needs. There are obvious deficiencies in these devices used to measure the seepage deformation parameters of fine sand and tailings soil. For example, the size is too large, the operation is cumbersome, the controllability is poor, the function is single, and the...
