The invention discloses a rock and earth mass water absorption test device, comprising a base, a water circulating system and a water level control system, wherein a first support and a second support are arranged on the base; in the water circulating system, a water collecting tank is fixed on the base, an overflow tank is arranged at the upper end of the first support, the inner part of the overflow tank is divided into a left tank and a right tank through a vertical division plate, the vertical division plate is lower than the periphery of the overflow tank, the water collecting tank is connected to the bottom of the right tank through a water injection pipe, a water pump is arranged on the water injection pipe, and the bottom of the left tank is connected to the water collecting tank through a return pipe; in the water level control system, a balance trough is arranged at the upper end of the second support, a horizontal division plate is arranged in the balance trough and uniformly provided with a plurality of holes, the upper surface of the horizontal division plate and the top end of the vertical division plate are positioned on the same horizontal line, one end of a water conduit is communicated with the bottom of the right tank of the overflow tank, the other end of the water conduit is communicated with the balance trough, and a liquid flow meter is arranged on the water conduit. The device has the advantage of realizing automatic stabilization of the water level of the water absorption interface of a rock and earth mass sample in water absorption test.
Description
technical field [0001] The invention relates to the technical field of water absorption test devices, in particular to a rock and soil body water absorption test device. Background technique [0002] In order to study the characteristics of water absorption and water absorption rate of rock and soil mass with time, water absorption test, especially non-pressure water absorption test is widely used. Nowadays, the test devices for unpressurized water absorption of rock and soil are complicated and there is no unified test device. In most non-pressure water absorption tests, the rock-soil sample is in direct contact with the water surface to absorb water. After the rock-soil sample absorbs water to make the water level drop to a certain extent, water is added to make the water level rise. This kind of water absorption test is inconvenient to operate, and accompanied by changes in water level and water pressure, it is impossible to accurately obtain the characteristics of water...
