Abstract

PURPOSE:To prevent an impervious sheet from floating up, by exposing air-paths connected to openings, at the rear face of a body and water-tightly arranging exhaust air cylinders provided with the openings which can be opened or closed, at the front face of the impervious sheet body. CONSTITUTION:An impermeable and flexible impervious sheet body 1 is made of vinyl chloride resin sheet or the like. Exhaust air cylinders 2 are formed with a rigid synthetic resin material. Air-paths connected to the openings of exhaust cylinders and connected to pierced holes formed in appropriate positions of the body 1 are exposed on the rear face of the body 1. These are arranged watertightly. A wire rope 5 having a float 4 at the front end is attached to the exhaust cylinder 2. In this way, entrapped air between the body 1 and the water bottom is purged into the water through the exhaust cylinders 2 and hence, the impervious sheet is prevented from floating.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-blocking sheet laid on a landfill provided in a harbor, a coast, a river, a lake or the like, or on the inner surface of a revetment in an industrial waste treatment plant and the water bottom. .

2. Description of the Related Art Conventionally, a part of the sea area and water area is surrounded by a seawall,
The earth and sand are buried inside it, or used as a place to put industrial waste, etc., but harmful components contained in the earth and sand that are put into the water dissolve in water and permeate through revetments and bottoms. Moreover, there is a concern that it may flow out into the surrounding sea area and water area, causing environmental pollution, which is not preferable.

Therefore, in order to prevent outflow of harmful components to the surroundings, it is practiced to lay a water-blocking sheet on the inner surface of the revetment and the bottom of the water.

In this laying, in order to lay the water blocking sheet over the inner surface of the revetment and the water bottom, for example, a plurality of water blocking sheet pieces are floated at predetermined positions on the water surface in the landfill and their side edges are floated. A common method is to join them together to form a wide impermeable sheet, and then settle the impermeable sheet and lay it on the bottom of the water and the inner surface of the revetment, but the landfill is vast and It is difficult to lay it without air intervening between it and the bottom of the water.

Further, when the impermeable sheet is laid, the plants and seafood inhabiting the water area are killed by being sandwiched between the bottom of the water and the impermeable sheet, and the spoiled gas causes the impervious gas. A large amount will be retained between the bottom and the bottom of the water.

Therefore, for example, as shown in FIG. 4, an exhaust pipe 3a having a tip portion inserted between a water-blocking sheet 1a and a water bottom 2a is placed along a slope 5a of the seawall 4a and a top portion 6 of the seawall 4a is provided.
A means for exhausting the gas interposed between the water-blocking sheet 1a and the water bottom 2a by being extended to a is adopted. However, the conventional exhaust means installs the exhaust pipe 3a along the revetment 4a, eliminates the gas in the vicinity of the revetment 4a, and eliminates the gas staying at a position away from the revetment 4a. It is difficult.

Therefore, it is preferable when the water blocking sheet is laid in a small area such as a reservoir, but when the water blocking sheet is laid over a wide area, the water blocking sheet 1a is used.
There is a problem that the gas interposed between the water and the water bottom 2a cannot be exhausted.
