での通過を許容する防水シート。[Claims for Utility Model Registration] 1. A layer consisting of small granular pieces of water-swellable clay is adhered to at least one surface of a water-impermeable sheet such as polyethylene, and the layer is applied to the bottom wall, side wall, or floor of a civil engineering or building structure. , a waterproof sheet used for waterproofing places where there is a risk of water leakage, such as water pipes, wherein the waterproof sheet is further applied to the surface of the layer consisting of the granular pieces of the water-swellable clay, A porous sheet sandwiching and holding the water-swellable clay layer between the water-permeable sheet and the porous sheet allows granular pieces of the water-swellable clay to pass through the porous sheet while the water-swellable clay is in a dry state. The mesh size is large enough to prevent water from falling to the outside, and when it absorbs water and swells to form a gel, it has a mesh size that allows the formed gel to pass through and flow to the outside. A tarpaulin sheet that prevents it from falling off when it is in a gel state and allows it to pass through when it is gelled. 2. The waterproof sheet according to claim 1, wherein each of the granular clay layers has a particle size of 5-150.
The mesh size of the porous sheet is in the range of 150-440 meshes, and prevents the water-swellable clay from falling off in a dry state and maintains it in a gel state. A tarpaulin that allows the passage of. 3. The waterproof sheet according to claim 1 or 2, wherein the mesh size of the porous sheet is 15.
A waterproof sheet which prevents water-swellable clay from falling off in a dry state and allows passage of water-swellable clay in a gelled state, characterized in that the mesh is within the range of 0-330 mesh. 4. The waterproof sheet according to any one of claims 1 to 3, wherein the granular clay layer and the porous sheet disposed on the upper surface thereof,
A waterproof sheet that prevents the water-swellable clay coated on both sides of the water-impermeable sheet from falling off in a dry state and allows it to pass through in a gelled state.
