The present invention is directed to a sensor-enabled geosynthetic material for use in geosynthetic structures, a method of making the sensor-enabled geosynthetic material, and a method of measuring geometric strains of a geosynthetic product made from the sensor-enabled geosynthetic material. The sensor-enabled geosynthetic material includes a polymeric material and an electrically conductive filler. The polymeric material and an electrically conductive filler are combined to provide a sensor-enabled geosynthetic material. The sensor-enabled geosynthetic material having a predetermined concentration of the electrically conductive filler so as to provide the sensor-enabled geosynthetic material with an electrical conductivity and a strain sensitivity within the percolation region or slightly above it.

摘要:
Geocomposite articles that can provide a barrier against high conductivity water e.g., ocean water, are described and their method of manufacture, for waterproofing surfaces that contact high conductivity water. The geocomposite article mat includes a woven or non- woven geotextile sheet or mat containing a powdered or granular partially cross-linked acrylamide/acrylate/acrylic acid copolymer across its entire major surface(s). The powdered or granular copolymer has an unexpectedly high free-swell when hydrated with High Conductivity water, such as ocean water. A liquid-impermeable cover sheet is adhered to the upper major surfaces of the filled copolymer-carrying geotextile to provide a primary high conductivity water barrier layer that, if ruptured, is sealed by the swell of an underlying layer of water-insoluble, partially cross-linked acrylamide/acrylic acid copolymer.
摘要:
A composite (1) for geotechnics, building and the like, with an impermeable layer, comprising a sheet-like element (2) that is impermeable to fluids and has, monolithically therewith, elements (10, 12) that protrude on the first and second faces, on at least one of the faces there being a layer (5) that is integrally coupled to the protruding elements to form, at the first and/or second faces, two separate drainage and/or protection and/or grip systems adapted to withstand intense compression along a direction that is substantially perpendicular to the sheet-like element.
摘要:
Die Erfindung betrifft ein Verfahren zum Beschichten oder Auskleiden eines Untergrundes, eines Beckens, eines Kanals oder dergleichen mit einer Dichtungsfolie oder -platte, dadurch gekennzeichnet, dass zumindest eine Lage (2) aus Verbundmaterial, wie ein Vlies, auf den zu beschichtenden oder auszukleidenden Untergrund aufgebracht wird und schmelzflüssiges Hotmelt (3) unmittelbar auf die Lage (2) aus Verbundmaterial aufgespritzt wird, wobei das schmelzflüssige Hotmelt (3) bei einer Auftragstemperatur kleiner oder gleich der Schmelztemperatur des Verbundmaterials aufgespritzt wird, und nach Aushärten des schmelzflüssigen Hotmelts zumindest eine Schicht aus Hotmelt gebildet wird.
摘要:
Reactive geocomposite mats, and their method of manufacture, for treating contaminants in soil or water that allow the passage of essentially non-contaminated water therethrough. The geocomposite mat includes a pre-formed woven or non-woven geotextile, having a thickness of about 6 mm to about 200 mm, and having, a porosity sufficient to receive a powdered or granular contaminant-reactive material, contaminant-sorptive material, or a contaminant-neutralizing material (hereinafter collectively referred to as "contaminant-reactant material" or "contaminant-reactive material") throughout its thickness, or in any portion of the thickness across its entire major surface(s). The powdered or granular contaminant-reactive material is disposed within the pores of the previously formed, high loft geotextile mat to surround the fibers, e.g., by vacuum or vibrating the high loft mat while in contact with the contaminant-reactive material to allow the powdered or granular contaminant-reactive material to flow by gravity into the pores of the previously formed geotextile and vibrational forces. Liquid-permeable cover sheets are adhered to the upper and lower major surfaces of the filled geotextile to prevent the powdered or granular material from escaping from the geotextile during transportation and installation.
摘要:
The invention relates to a seal in order to prevent the exit or entry of liquids out of or into systems and the application thereof. According to the inventive solution, a seal should be provided which prevents liquids from exiting a system or from being able to enter such a system with a high certainty and over a long period of time. To this end, a nonbiodegradable polymer which is capable of swelling by imbibition or at least two components which reactively form such a polymer are accommodated in a space which separates both systems from one another. The invention can be favorably utilized in order to seal pipes or to seal waste disposal sites.
摘要:
A water and oil impermeable geosynthetic clay liner formed by supporting a layer (10) of bentonite on an impermeable plastic layer. Integrally formed protrusions (14) extend from one surface of the plastic layer to support a permeable plastic cover layer. The cover layer (15) confines the bentonite clay layer and is heat-sealed to the protrusions.
