摘要:
An assembly (1) for moving vehicles and apparatuses, particularly for the provision of the impermeable mantle of canals, basins, dams and the like, which comprises a dolly (2) which is provided in an upward region with a resting surface (3) and has a height substantially similar to the height of an element (M) which is chosen from among a breakwater wall, a toe wall, a top barrier and the like, of the canal, basin, dam and the like; the base of a winch truck (4) is rigidly coupled on the resting surface (3) in order to firmly anchor the apparatuses operating on a facing (P) of the canals, basins, dams and the like.
摘要:
A method for forming a geomembrane liner testable for leaks by securing adjacent panels together with the conductivity of the lower surface of an overlying panel broken along a line adjacent the panel overlapping edge, and the overlapping edges sealed along the line. A heat welder has slots for the overlapping panel edges, with a heated wedge between the slots and having a projection to break the conductivity of the overlying panel bottom surface as it passes the wedge. The slots merge to press the liner edges together to heat weld them along the line of broken conductivity as the welder is moved along the panel edges.

The invention relates to a device and a method (1) for flood protection, coastal protection and scour protection. The aim of the invention is to provide an economical, durable and effective form of protection. To this end, the device (1) comprises at least one elastic plate (2, 75) and fixing means (3) for fixing the plates to the points (12) to be protected. The invention also relates to a method, according to which at least one elastic plate (2, 75) is fixed to the points (12) to be protected using fixing means (3).

The invention relates to a waterproof seal for surfaces in hydraulic and civil engineering, especially for traffic routes, tunnels, embankments, bottoms, channels, dykes, dams, tubs, basins, basements, and underground parking garages. Said waterproof seal comprises a surface seal (3) which is particularly made of swelling fleece and lies on the surface (1) that is to be sealed. A cell structure (5) whose cell walls are provided with strips (5a) that have a sealing effect and are made especially of swelling fleece is arranged on top of the surface seal (3). The cell walls, above all the fleece strips, stand upright and/or at an angle on the surface seal (3) and are fixed to each other in a contacting, particularly an intersecting manner, while the cells (7) are filled with concrete or mortar.

A gutter block structure of the present invention has a configuration in which a vegetable fiber layer made of palm fibers or the like is integrally attached to an inner surface of a water-permeable concrete material, sidewall surfaces which serve as the inner surface are formed into a stepped shape, and a bottom surface which serves as the inner surface is formed into an irregular shape. Further, both the sidewalls are formed into a curved shape or S-shape. Thus, when a water channel is formed by the gutter block structures, the supply and drain of water between the water channel and the surrounding soil is enabled, the flow velocity of water can be reduced, and zones with different flow velocities can be provided. Thus, an environment at the water channel and around the water channel can be closer to a natural condition, and an environment for growing underwater creatures can be brought into a fairly good condition.

The present invention relates to geotextile/polyurethane/polyurea and/or geotextile/polyurea composites prepared by soaking geotextiles with one-component heterogeneous liquid polyurethane compositions and subsequently curing by heat or solvent addition to form a geotextile/-polyurethane composite. The inventive composites may find use as liners for canals and ditches for irrigation and wastewater, roof membranes, secondary containment, etc.
摘要:
A method of lining an irrigation canal (10) with a sheet of fiber-reinforced plastic includes the steps of depositing a layer of resin and fiber on a web of flexible carrier material, partially curing the resin prior to laying the sheet in the canal, and then laying the sheet in the canal while the resin is flexible enough to conform to the shape of the canal. The final curing of the resin takes place after the sheet is placed in the canal. A predetermined-shape wrinkle (38) is induced in the carrier web before it is laid into the canal to assist in conforming the sheet to the canal shape without causing randomly placed wrinkles so that the sheet is smooth in the canal. An apparatus (18) is disclosed that forms the sheet and is propelled so that it travels along the length of the canal, fabricating a continuous sheet as it travels. In one embodiment the carrier is a flexible but nonelastic material like kraft paper, coated on one side with wax or other film to prevent saturation by the resin.

摘要:
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.
