Un remblai ou un talus, surtout un talus insonorisant, est construit à l'aide de sacs en forme de tube et résistant au pourissement (1, 2) remplis de matériaux granulés ou sablonneux, servant de matériaux de construction. Les sacs sont empilés en rangées de manière à s'imbriquer, et sont placés selon l'angle de pente. Les sacs (1) de la rangée au niveau du sol ainsi que de chaque rangée impaire sont placés à angle droit par rapport au mur, et les sacs (2) de chaque rangée paire sont placés dans le sens longitudinal du mur, les sacs étant supportés sur au moins deux sacs situés perpendiculairement au mur. Les sacs (1) situés perpendiculairement au mur sont placés à des intervalles de 20 à 80 cm, et les ouvertures ainsi créées entre les sacs sont remplies de terre et au moins partiellement d'humus, de sorte que des niches pour plantes sont réalisées dans le mur en pente composé de sacs (1, 2), présentant ainsi une couverture de verdure assurée pour le mur.

A method, a waterproof liner and waterproof panels for installations in basins and canals) both dry and with stationary and flowing water. The liner consists of a plurality of prefabricated panels, including at least one flexible waterproof membrane, made of geosynthetic material, provided with side anchor bands for anchoring to the ground and with side sealing flaps. The panels that are rolled up into rolls are sequentially unrolled and extended by fixing provisionally along at least one anchor band, by joining simultaneously the flaps of adjoining panels by means of an intermediate zip fastener. Subsequently, the individual panels are firmly anchored by friction to the bottom and/or to the banks of the basin or canal, by means of a permanent ballast. The individual panels can be removed and replaced by operating underwater, restoring the seal between panels of the entire waterproof liner.
摘要:
A water swelling water stop material comprised of a water permeable sheet, characterized in that water absorbent resin particles (A) are enclosed therein so that the water stop material upon water absorption and swelling has the configuration of polyhedron (B). The water stop material is thin to thereby facilitate storage thereof and is lightweight to thereby render carry thereof easy. The polyhedron (B) is so constructed that upon water absorption and swelling, at least two faces are planar. When the polyhedron (B) is formed into a rectangular solid or cube, even if multiple polyhedrons (B) are piled one upon another, they are stable and are resistant to collapse even under the influence of a large amount of water. When polyhedrons (B) of the same configuration are piled one upon another, any gaps between water stop materials are slight so as to inhibit water leakage through the gaps. Moreover, when the polyhedron (B) has a cavity, the cavity can be packed with a heavy solid material or can have a stake hammered therein so that the water stop material can stably resist violent water streams. Therefore, this water swelling water stop material can be appropriately used as a water stop material for rainwater penetration prevention in order to protect banks, buildings, houses, etc. in the event of flood, heavy rain, etc.

There is described a barrage unit comprising a porous bag or sack (1) containing an absorbent core (3) said absorbent core (3) comprising an absorbent crystalline material and an absorbent fibrous material.
摘要:
A method of manufacture of a barrage unit comprising providing a chamber having an outer wall having at least one aperture therein; providing a liner layer proximate to the aperture; blowing the fibers of a fibrous material into the chamber whilst providing an absorbent crystalline material to the chamber such that the two mix and exit the aperture onto the liner forming a pad; and, providing a further liner layer on the pad.

A sandbag (10,10A,10B,10C,10D,10E,10F) is made of synthetic fibers, is an integral, woven, hollow and elongated element and has an upper cloth (11,11A), a lower cloth (12,12A), two lateral strengthened strips (13,13A,13B,13D,13E,13F), a stuffing space (15) and an inlet (16). The lower cloth (12,12A) is woven with the upper cloth (11,11A). The lateral strengthened strips (13,13A,13B,13D,13E,13F) are respectively formed on two opposite sides of the sandbag (10,10A,10B,10C,10D,10E,10F) and are integrally woven with where long sides of the upper cloth (11,11A) and the lower cloth (12,12A) are connected. The sandbag (10,10A,10B,10C,10D,10E,10F) is produced as an integral element and has the lateral strengthened strips (13,13A,13B,13D,13E,13F), so the structural strength of the sandbag (10,10A,10B,10C,10D,10E,10F) is greatly enhanced and a lifespan of the sandbag (10,10A,10B,10C,10D,10E,10F) is prolonged.
