Abstract
The utility model relates to a hydraulic head adjustment and stabilization device of a measurement device for the vertical water permeability of the soil engineering synthetic material and is composed of a test hole at the center on the bottom, water inlet holes at two sides, an upper test trough connected with a plastic pipe and on a hydraulic head adjustment hole, an upper controller and a lower adjustment controller on the hydraulic head adjustment hole. The upper controller and the lower adjustment controller on the hydraulic head adjustment hole are composed of a frame, a leading screw member and a driving motor. When in test, the height of the hydraulic head is adjusted through the position of the hydraulic head adjustment hole, the stabilization for the hydraulic head with an overflowing method is realized, the velocity of the flow at the test hole at the center on the bottom is measured, the truth of the test results is ensured and the test precision are maximally ensured.
Description
Affiliated technical field:
The utility model relates to a kind of geotechnological material properties test instrument, relates in particular to the vertical water permeability tester of a kind of geotechnological material head and regulates stabilising arrangement.
Background technology:
At present, the vertical water permeability tester of known geotechnological material, by a bottom center porose and add down the orchid of enforcing the law and form specimen holder, geotechnique's material sample is added is held in the centre, the flow velocity of regulating the head change bottom center instrument connection in the testing flume by the head regulating device promptly flows through the flow velocity of geotechnological material sample, obtains the vertical water permeability of geotechnological material by the flow velocity that flows through geotechnological material sample and the relation curve of head.The flow velocity of geotechnique's material sample is obtained by the water yield of collecting in the feeder in the unit interval.During test, the test water is directly added above last testing flume by running water pipe, the control of head is to realize by the flow of water in the control running water pipe, because the water pressure fluctuations of running water pipe is bigger, the instability of flow of Guan Zhongshui, the height of the head in the last testing flume is difficult to control, and goes up the height variation of the head in the testing flume, bigger to the flow rate effect that flows through geotechnological material sample, and then test result produced big influence.
The utility model content:
The purpose of the utility model is not enough at above-mentioned existing in prior technology and the vertical water permeability tester of a kind of geotechnological material head adjusting stabilising arrangement that provide.
For achieving the above object, the utility model can be achieved through the following technical solutions: the vertical water permeability tester of geotechnological material described in the utility model head is regulated stabilising arrangement, comprises that last testing flume that a bottom center is regulated mouthful by water inlet and by the head that sebific duct connects respectively by instrument connection, both sides and head regulate a mouth up-down adjustment controller and form.Head is regulated a mouthful up-down adjustment controller and is made up of support, lead screw assembly, drive motor.During test, water is introduced from water inlet by running water pipe and is gone up testing flume, regulate the height of mouth position adjustments head up and down by regulating head, method with overflow realizes the stable of head, the flow velocity that records the bottom center instrument connection under stable head promptly flows through the flow velocity of geotechnological material sample, guarantees the authenticity of test result.
The beneficial effects of the utility model are, the vertical water permeability tester of geotechnique's material is in test process, can regulate the height of mouth position adjustments head up and down by regulating head, method with overflow has realized the stable of head, the flow velocity that records the bottom center instrument connection under stable head promptly flows through the flow velocity of geotechnological material sample, guarantee the authenticity of test result, guaranteed measuring accuracy to greatest extent.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
In Fig. 1, the utility model comprises that a bottom center has instrument connection 6, both sides are respectively by water inlet 7 and regulate mouthfuls 4 last testing flume 1 and head by the head that sebific duct 5 connects and regulate mouth 4 up-down adjustment controllers and form, head is regulated a mouthful up-down adjustment controller and is comprised support 2, the lead screw assembly 3 that is movably arranged on the support 2 and on support 2, moves up and down, drive the drive motor 8 that lead screw assembly 3 moves up and down at support 2, drive the lead screw assembly 3 that is connected with support 2 by drive motor 8 and move up and down, and then regulate head and regulate the control that the head height is realized in the position of mouth about in the of 4.There are instrument connection 6, both sides that water inlet 7 is arranged respectively and regulate mouthfuls 4 last testing flume 1 and head by the head that sebific duct 5 connects and regulate mouth 4 up-down adjustment controllers and fuse by bottom center.
During test, water is introduced from water inlet 7 by running water pipe and is gone up testing flume 1, driving the lead screw assembly 3 that is connected with support 2 by drive motor 8 moves up and down, and then regulate head and regulate the control that the head height is realized in the position of mouth about in the of 4, method with overflow realizes the stable of head, the flow velocity that records bottom center instrument connection 6 under stable head promptly flows through the flow velocity of geotechnological material sample, guarantees the authenticity of test result, guarantees measuring accuracy to greatest extent.
