Permeability testing measures the rate of discharge of 水 under laminar flow conditions through a unit cross-sectional area of a porous medium under a unit hydraulic gradient and standard (20°C) temperature conditions. In permeability testing, soil is subjected to 水 under a known pressure, and the flow is measured. 渗透系数(k), 或者简单的渗透性, expresses the ability of 水 to flow through the particular medium. The “constant head” test method is applicable to course granular soils such as sands and gravels. The “falling head” test method is applicable to fine grain soils. 任何一种方法都可用于测试粘土.
洪堡FlexPanels
洪堡FlexPanels provide a simple and highly efficient distribution system for providing air, 水 and de-aired 水 f或使用 in permeability and triaxial testing applications. FlexPanel很简单, 简单的配置, with its integral burettes provides a condensed/compact design that takes up less counter space than competing systems with air/水 bladders. 长, narrow burette design of 洪堡's FlexPanels provide faster test processing times when compared to larger, 较短的滴管系统, 同时提供相同的体积. This is due to the reduced amount of meniscus formation in the narrower burettes, 哪个能让水位下降得更快, 读取速度更快. In addition, the use of longer/narrower burettes and a scale graduation of 0.02ml, also provides an easier-to-read and more accurate scale.
FlexPanels also feature a bias regulator and bridge. The bias regulator maintains the differential pressure when confining and back pressures are increased. The bridge delivers simultaneous control of base and top pressures through the use of just one regulator. This feature minimizes operator time and reduces the margin of error in opening and adjusting regulators during a test. The 洪堡 FlexPanel system is comprised of 5 separate panel configurations, which can be grouped together to accommodate from 1 to 6 cell setups.
快速和容易的设置和操作
洪堡FlexPanels make setup fast and easy with clearly labeled ports and quick-connect hookups. Operation is just as easy with clearly labeled controls, large gauges and easy-to-read burette markings. All inlets and outlets utilize quick-connects to ensure fast, 准确设置渗透计细胞, 还有空气, 供水和排水连接. Fittings, tubing and connectors are supplied with each unit. All FlexPanels are designed to handle air pressures up to 150 psi. 用于检测污染样本, 洪堡 offers an optional 有毒界面小组, which prevents toxic fluids and vapors from entering the FlexPanel. 见正面页.
洪堡flexpanel的特点:
洪堡FlexPanels are constructed of lightweight aluminum for long, rust-free life. FlexPanels provide an accurate and easy-to-operate solution for controlling compressed air, 水, de-aired 水 and vacuum without the need for air/水 bladder interfaces to produce the pressures necessary for permeability and triaxial testing. FlexPanels utilize a set of three burettes to control cell, top cap and base pedestal pressures. This extremely versatile pressure system controls the pressure, 水, 脱气罐和真空从一个面板. The three burettes allow for the control of the cell pressure and the back pressure for each cell. They can monitor volume change in the sample and can be used to measure the flow of 水 through the sample for permeability testing. FlexPanels can manually measure volume change or permeability in a triaxial test sample without the use of a volume change apparatus, a distinct benefit when compared to air/水 bladder systems.
