Description

Penetration test equipment for soil engineering

Technical Field

The utility model relates to the technical field of geotechnical permeability tests, in particular to permeability test equipment for geotechnical engineering.

Background

The geotechnical permeability test is a test for measuring the permeability coefficient of rock soil or soil by using a test instrument and is divided into an indoor test and a field test. The geotechnical permeability test is also a test commonly performed in engineering at present, and the types of instruments and test methods for measuring the permeability coefficient in a laboratory are many, but the geotechnical permeability test can be roughly divided into a normal water head method and a variable water head method in the test principle.

The variable head permeability is mainly researched, and the preparation of a sample comprises the following steps: cutting an undisturbed sample or disturbed soil on the vertical or parallel soil sample layer by using a cutting ring to prepare a sample with a given density, and fully saturating. Coating a thin layer of vaseline on the inner wall of a sleeve of the permeameter, pushing a cutting ring containing a sample into the sleeve, and pressing a water gasket. The upper cover and the lower cover with water permeable holes are assembled and screwed tightly, so that air leakage and water leakage cannot occur. The height of the water head communicated with the water head device after being assembled is not more than 2 m. And injecting the water into a permeation container after the water head is stable. And turning on a drainage valve, inverting the container, and draining air permeating the bottom of the container until no air bubbles exist in overflowing water. The vent valve was closed and the permeation vessel was laid flat. Standing for a period of time under the action of a certain water head, and beginning to perform test measurement when water overflows from a water outlet pipe opening. After the water is filled to the required height through the water head pipe, the water clamp is closed, the initial time of the variable water head is measured and recorded, and the water temperature of the water outlet is measured and recorded. The test is repeated 5-6 times after several successive measurements. And finally, measuring the permeability coefficient.

The backplate has the steel tape measure as the scale, also has directly to the scale on the backplate, no matter which kind of existence, because height problem, the rear chi reading of glass pipe that every experimental soil sample device connects is because the reading needs look up or because individual eyesight problem, easily produces reading error, surveys the temperature problem, and the temperature of water all will be tested in every experiment, owing to need take the thermometer test, wastes time and energy.
