Abstract

The invention belongs to the technical field of geotechnical instruments and particularly relates to a horizontal permeameter for geotextile. The horizontal permeameter comprises a permeation measuring device and a gas and water removing device, wherein the gas and water removing device is arranged on the left side of the permeation measuring device, and the permeation measuring device comprises a first-stage support platform, a permeation chamber, an object table, a press block and a support block; the permeation chamber is arranged at the top of the first-stage support platform, an infiltration water container is arranged on the first-stage support platform on the left side of the permeation chamber, an exudation water container is arranged on the first-stage support platform on the right side of the permeation chamber, the object table is arranged at the bottom in the inside the permeation chamber, the press block is arranged above the object table, and an inverted-U-shaped groove allowing the object table to be inserted in is formed in the bottom of the press block. The horizontal permeameter for the geotextile can test the horizontal permeation performance of the geotextile in a laboratory, obtains more accurate and stable test results and has the advantages of being simple in structure and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of geotechnical instruments, in particular to a geotextile horizontal permeability meter. Background technique [0002] Geotextiles are civil engineering rolls made of synthetic fiber weaving or non-woven processes such as cementation and hot-press needle punching. Water-filtering geotextiles allow water to pass through and prevent fine-grained soil from losing with water. Permeability is one of the important hydraulic properties of water-filtering geotextiles, which directly affects the application method and use environment of geotextiles. Due to the wide variety and different properties of geotextiles, their permeability is often tested by field tests. In-house testing of geotextile permeability is positive because it provides more accurate and consistent results. Most of the existing indoor permeability testing devices are designed for soil, but few are designed for geotextiles. Contents of the inven...
