Abstract
The utility model relates to an anti-side-leak device of a vertical permeability measurement device for the soil engineering synthetic material and is composed of an upper test trough with a test hole at the center on the bottom and a fixture composed of a hole and a water-holding trough. The water-holding trough is provided with a side leakage outlet opening. The tested soil engineering synthetic material is positioned between the upper test trough and the water-holding trough. The water-holding trough is communicated with the side leakage outlet opening. When in test, the water flowing from the tested soil engineering synthetic material is colleted by the water-holding trough, guided through the side leakage outlet opening without any influence on the test results, prevented backflow to the collecting trough from affecting the test results, thereby ensuring a maximum test precision.
Description
Affiliated technical field:
The utility model relates to a kind of geotechnological material properties test instrument, relates in particular to the anti-side leakage device of the vertical water permeability tester of a kind of geotechnological material.
Background technology:
At present, the vertical water permeability tester of known geotechnological material, by the porose last testing flume of a bottom center with add the orchid of enforcing the law down 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, water flows out from geotechnological material direction finding and flows into the feeder, influences test result, and particularly when the test head was low, the instrument connection flow velocity was slower, and the influence of sample side leakage water more can not be ignored, and is bigger to the influence of test result.
The utility model content:
The purpose of the utility model is not enough at above-mentioned existing in prior technology and the anti-side leakage device of the vertical water permeability tester of a kind of geotechnological material 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 is prevented the side leakage device, comprise the last testing flume that bottom center is porose, form specimen holder by last testing flume and following kamochi flume with holes that bottom center is porose, be provided with the side leakage water delivering orifice on the kamochi flume with holes down, geotechnique's material sample is added by bolt to be held in the middle of porose last testing flume of bottom center and time kamochi flume with holes, and following kamochi flume with holes and side leakage water delivering orifice fuse.During test, the water that flows out from geotechnological material direction finding is collected by kamochi flume, is walked the unlikely test result that influences by the side leakage water delivering orifice drainage on the kamochi flume.
The beneficial effects of the utility model are that the vertical water permeability tester of geotechnological material can prevent that sealing flows out the inflow feeder from geotechnological material direction finding in test process, influence test result, has guaranteed measuring accuracy to greatest extent.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
In Fig. 1, comprise the last testing flume 1 of a bottom center porose 3 and kamochi flume 5 down with holes and down the side leakage water delivering orifice 7 on the kamochi flume 5 with holes form specimen holders, geotechnique's material sample 4 is added by bolt 2 fixing quilts is held in the centre, the flow velocity of regulating the head change bottom center instrument connection 3 in the testing flume 1 by the head regulating device promptly flows through the flow velocity of geotechnological material sample 4, obtains the vertical water permeability of geotechnological material by the flow velocity that flows through geotechnological material sample 4 and the relation curve of head.The flow velocity of geotechnique's material sample 4 is obtained by the water yield of collecting in the feeder in the unit interval 6.During test, the water that flows out from geotechnological material direction finding is collected by kamochi flume 5, is walked by side leakage water delivering orifice 7 drainages on the kamochi flume 5, and the unlikely test result that influences guarantees measuring accuracy to greatest extent.
