Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Example (b): a hydrostatic pressure resistance and permeability coefficient tester for geosynthetics.
As shown in fig. 1 and 2, the geosynthetic material hydrostatic pressure resistance and permeability coefficient tester comprises a machine table 3, a lower pressure plate 4, an upper pressure plate 5, a cover 8 and a graduated tube 9. The lower pressure plate 4 and the upper pressure plate 5 are arranged in a working chamber 12 on the surface of the machine table 3, and the lower pressure plate 4 and the upper pressure plate 5 are fixed by bolts for clamping a sample 17. The inner ring part of the upper pressure plate 5 is fixedly provided with a pore plate 7 for protecting a sample 17, and the pore plate 7 is provided with a plurality of pores, so that the hydrostatic pressure resistance test is not influenced. Be equipped with on the orifice plate 7 and cover 8, cover 8 tops and be fixed with connection piece 10, be equipped with through-hole 14 on the connection piece 10, go up pressure disk 5 and correspond the through-hole 14 position and be equipped with screw 19, screw rod 18 passes through-hole 14 and is connected with screw 19 and can be fixed with covering 8 to cover 8 bottom round and be equipped with sealing washer 16, can improve its leakproofness. Cover 8 top and be equipped with connector 11, scale tube 9 threaded connection is in connector 11, covers and is equipped with the filler 13 that can open and close on 8, and filler 13 department is equipped with the valve for the infiltration coefficient survey in-process is to covering 8 in water addition. The working chamber 12 is provided with a water outlet 6 for discharging excess water in the cover 8 after the test is finished.
