Abstract

The invention discloses a multi-connected flexible wall permeameter. The multi-connected flexible wall permeameter comprises a support, wherein a transparent cylinder body is arranged in the support; a top cover covers an upper end of the transparent cylinder body; a penetrating fluid conveying device is communicated with one end of a soil test sample through a liquid inlet pipe; a bath foam collection bottle is communicated with the other end of the soil test sample through a liquid drainage pipe; an inner cavity of the transparent cylinder body is connected with a water inlet pipe and a water drainage pipe; an upper end and a lower end of the soil test sample are connected with an air exhaust pipe; a pressure reducing channel is arranged in the top cover and is equipped with a pressure reducing valve; pressurizing branch pipes are communicated with the interior of the transparent cylinder body through the top cover and are provided with check valves; a plurality of flexible wall permeameters are arranged; pressurizing branch pipes of all flexible wall permeameters are all connected with a pressurizing main pipe in a guiding manner; the pressurizing main pipe is connected with a pressurizing pump. The multi-connected flexible wall permeameter is labor-saving in operation, and air pressures of all permeameters can be synchronous and consistent, so that permeability coefficients obtained by the test can be more accurate.

Description

technical field [0001] The invention relates to a multi-connected flexible wall permeameter, which is mainly used for the permeability coefficient of soil samples. Background technique [0002] The traditional flexible wall permeameter consists of a permeation device, an air-water isolation liquid supply device, an exudate metering tube, a data acquisition and processing system, and an air pressure source. The press is connected, the permeation device is connected to the gas-water isolation liquid supply device and the permeate metering pipe through the permeate pipeline and the permeate pipeline respectively, and the data acquisition and processing system is connected to the permeation device through the signal line and the pressure sensor and temperature sensor , connected with the exudate metering tube through the signal line and the exudate volume sensor. This kind of flexible wall permeameter requires a single pressurization operation, and often needs to be equipped wi...
