Title: Bag for dehydrating sludge
Inventor: ENDO SHIGERU
IPC: C02F11/12
Filed: 1994-09-28
Abstract: PURPOSE: To reduce a load exerted by a bag for dehydrating sludge on the soft ground and to prevent a sinking of the ground by constituting the bag for dehydrating sludge by incorporating a floatation body having a specific gravity lower than that of water into a bag body formed of nonwoven fabric high in corrosion resistance and tear resistance and capable of permeating only water. CONSTITUTION: The bag 1 for dehydrating sludge is constituted by incorporating the floatation body 3 consisting of a tubular perforated plastic foam provided with drilled plural circular holes 3a on the inside of a bag body 2 formed tubular with the nonwoven fabric consisting of polyester, glass or carbon fiber, or these mixture and high in corrosion resistance and tear resistance and capable of permeating only water. A sewing part of the bag body 2 is covered with a cover 4 consisting of belt-shaped nonwoven fabric. Moreover, a bag 1 for dehydrating sludge in which a dehydrated sludge is packed is used for a bulkhead by piling plural bags at the coast of a river, etc.  At this time, even if the bags are piled on the soft ground at a bottom of a river, the load exerting on the ground at the bottom of the river is reduced since the weight of the bag 1 for dehydrating sludge is reduced by the buoyancy of the floatation body 3. Therefore, the sinking of the ground is prevented.
