The Combination Permeameter is designed for laboratory determinations of permeability of either fine-grained or coarse-grained soils. Generally, soils containing 10 percent or more particles passing a no. 200 sieve are tested using the falling head assembly. More granular soils, containing 90 percent or more particles retained on the no. 200 sieve, are tested using the constant head assembly.
Including : Permeability Test Set compricing 4 permeability cells, 4 glass tubes, reservoir tank, metre scale, rubber tubes.
Since there are serious problems if fine grained soils are exposed to water flow, some test methods are applied to see how they are exposed. The function of the devices or test sets used in these test methods is very important and they are used to demonstrate that the products to be produced from fine-grained soils have a high level of durability when they are faced with water flow.
Among these products, especially the Permeability Test Set is the most functional product, the reaction of clayey and silty soils against water flow and the deformation caused by water flow are detected.
All these installations are offered as a set and there are apparatuses that can be adjusted according to the water transport and falling speed.
The experiments carried out by using these products, which are in the form of a water transport tank, a 100 mm falling level permeability cell, 1 3 m hose, 4 manometer tubes and a wooden stand set in this operator, give very professional and realistic results.
It is important to carry out the tests correctly, to reach the results closest to the truth, and to reveal the results with a minimum margin of error, in order to ensure safety at the points where the products to be obtained from the samples will be used in the future.
Since these soil types are used in the raw materials of the products used in areas such as roads or airports, road collapse or collapses at certain points in the airport in case of contact with water is a threat to human health, and all tests must be fully completed before use. The results of the tests must prove that the products are usable.
Permeability Test Set Features
Since test equipment produced in accordance with international standards must be used in terms of permeability test set features, and the results obtained with test equipment that do not comply with the standards will not be close to reality, you should definitely pay attention to which standards it is produced or not, when purchasing a product.
The Permeability Test Set is produced in accordance with BS 1377 and ASTM 46-47 Standards, and the test set with all valve connections consists of wooden stands with 1500 mm internal diameters.
In this test set, which is used in 4 different types of glass manometers as 21 mm, 12 mm, 3.5 mm and 5 mm, the transport pipes and water transport tank are covered with steel, providing long-term use and can be used as a very durable product. appears.
At this point, the tests to be used for the experiment must be purchased by considering the basic features and then used in the appropriate area.
