Abstract:
Ein Netzsystem (10) vorzugsweise für eine Böschungssicherung umfasst ein aus Drähten (12), Drahtlitzen, Drahtbündeln, Drahtseilen oder ähnlichem erzeugtes Netz (15). Dieses ist mittels Befestigungselementen (17) auf einer Erdoberflächenschicht (16) einer Böschung fixierbar. Dem Netzsystem (10) ist eine künstliche Grünstruktur (20), vorzugsweise ein künstlicher Rasen, zugeordnet. Diese Grünstruktur (20) ist zumindest über einen Bereich des auf der Erdoberflächenschicht ( 16) fixierbaren Netzes (15) gehalten. Damit ist eine natürlich aussehende Grünstruktur beispielsweise an einem felsigen Abhang geschaffen worden, bei welcher ansonsten ein steiniges bzw. erdiges Aussehen verbleiben würde. Zudem ist aber die Böschung auch gegen Steinschlag und/oder Erdrutsch gesichert.
Abstract:
Apparatus and method for placement of a subterranean curtain (2) below the face (5) of the earth, comprising the steps of: -selecting an area with soil in which the subterranean curtain (2) is to be placed; 5 -carving a slit at a predefined location in the soil; -providing a movable casing (8) in said slit; -providing the movable casing (8) with the curtain (2); -dispatching the curtain (2) from the movable casing (8) into the slit; 10 -closing said slit; -providing the subterranean curtain (2) as a waterpermeable curtain (2) in an area with a predefined stratification of a sand layer (3) and a clay layer (4) on top of said sand layer (3), using the steps of: 15 -carving a slit at a predefined location in said area comprising said sand layer (3) and said clay layer (4); and -after dispatching the waterpermemeable curtain (2) from the movable casing (8) into the slit, introducing sand 20 (3) and clay (4) in the slit on opposite sides of the water- permeable curtain (2) so as to close said slit and restore the area's original stratification of sand and clay.
Abstract:
Strong nonwoven fabrics can be used as a sheet in a silt screen fence or other temporary silt screen barrier. The fabrics can be without reinforcements. Enhanced features of these strong nonwoven fabrics can enable them to be used as a sheet in a silt screen fence or other temporary silt screen barrier without adding additional processing steps. A strong nonwoven fabric without internal or external reinforcement that does not tear easily and has excellent light stability can be used.
Abstract:
The present invention relates to a method of building a structure in which earthworks are used to prepare an area of ground (2) intended to accommodate said structure; a load-spreading mat (1) is created by adding compacted material within said area; and said structure is built on top of said load-spreading mat (1). Such a method is characterized in that it involves, during the creation of said mat (1), introducing a reinforcement (10) that is meshed during the compacting of said material.
Abstract:
La présente invention concerne un procédé de construction d'une structure, dans lequel on prépare par terrassement une zone d'un sol (2) destinée à recevoir ladite structure; on réalise un matelas de répartition (1) par ajout d'un matériau compacté au sein de ladite zone; et on réalise ladite structure en face supérieure dudit matelas de répartition (1). Un tel procédé se caractérise en ce qu'il consiste, lors de la réalisation dudit matelas (1), à introduire une armature (10) maillée lors du compactage dudit matériau.
Abstract:
The present invention is directed to a sensor-enabled geosynthetic material for use in geosynthetic structures and geosyntapes, a method of making the sensor-enabled geosynthetic material and the geosyntapes, 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.
Abstract:
According to the method on a surface to be protected is placed a geotextile (4) of a basis weight of 200 to 500 g/m2 and containing plant seeds (5) in its structure. Then the geotextile (4) is covered by a spatial geogrid (6) with spatial cells (9) of the sizes ranging from 200 to 500 cm2 and with a height of side walls (7) ranging from 20 to 50 mm. Next the spatial geogrid (6) is fixed to the ground by the anchors (10,1 1 ) and filled with humus (12). Te equipment set for implementing such method consists of a geotextile (4) with basis weight adjusted to the protected surface and of spatial geogrid (6) adjusted to the geotextile as well as of proper number of anchors (10,11).
Abstract:
Retaining wall systems and methods of making retaining wall systems are disclosed. In one embodiment, the retaining wall system includes a first horizontally-extending course of sand/soil bags and a second horizontally-extending course of sand/soil bags positioned vertically adjacent to the first course of sand/soil bags, with an interconnecting member that attaches the first course of sand/soil bags to the second course of sand/soil bags. The interconnecting member has an upper side and a lower side, wherein at least one of the upper side and the lower side has a first projection that includes a notch therein to engage geogrid.
Abstract:
