Embodiment Construction

[0016] The invention is designed for quickly and conveniently measuring the permeability coefficient of soil. The main purpose is to provide a reasonable, scientific and stable permeameter for rapid and accurate determination of the permeability of soil.

[0017] The utility model includes three parts: a water pressure output part, a water pressure control part and a variable water head osmometer.

[0018] The water pressure output part needs to ensure that it can output water flow with a certain pressure (about 1.1Mpa);

[0019] The water pressure control part is composed of a water pressure control switch, a tee part, a water pressure gauge and a high-strength rubber tube; (1) The basic composition of the water pressure output part

[0020] refer to figure 2 As shown, the water pressure output part consists of a welded steel frame (1), which includes a water pump (3), water storage tank (4), separator (5) and sensor (6) inside, and a supplementary water tank (2) on the ou...

Abstract

The invention relates to a pressurized variable water head permeameter which comprises a water pressure output part, a water pressure regulation part and a variable water head permeameter. The water pressure output part comprises a frame, a water supplementing tank, a valve, a water pump positioned inside the frame, a water storage tank, a separator, a sensor and a water pressure control panel, wherein the water supplementing tank is connected through a metal connecting pipe and is positioned outside the frame, the water pump, the water storage tank, the separator and the sensor are positioned inside the frame; the water pressure regulation part consists of a water pressure regulation switch, a water pressure gauge and high-strength rubber pipes; the high-strength rubber pipes are respectively arranged among a water outlet pipe a, the water pressure regulation switch, a three-way part and a water inlet pipe of the variable water head permeameter. Because the clay is low in permeability coefficient, the seepage passing through a soil sample is slow and the duration is long under the condition that the water head difference is small. The water pressure input into the permeameter is increased, so that the experiment process can be accelerated, the test efficiency is improved, and the test time is saved.

Description

technical field [0001] The invention relates to a pressurized variable water head osmometer, which belongs to the field of test instrument refitting, and relates to a variable water head osmometer capable of adding water pressure. Background technique [0002] The phenomenon that free water in soil pores moves under the action of gravity is called soil permeability. In engineering, it is often necessary to understand the permeability of the soil. For example, when excavating a foundation pit for drainage, it is necessary to understand the permeability of the soil in order to configure appropriate drainage equipment; when building a seepage embankment on a river beach, it is necessary to consider the permeability of the embankment filler; When studying the settlement of buildings on saturated cohesive soils as a function of time, it is necessary to grasp the permeability of the soil. The permeability coefficient k is an index that comprehensively reflects the permeability of...
