Title:
PRODUCTION OF WATER PERMEABLE POROUS BODY
Document Type and Number:
Japanese Patent JPH05178677
Kind Code:
A
Abstract:
PURPOSE: To provide a method for providing a water permeable porous body of arbitrary shape in low cost by using water permeable porous materials having mutually different coefficients of water permeability.
CONSTITUTION: Sand and an adhesive are mixed and kneaded and the kneaded substance is put in a form plural times while ramming by a rammer and released from the form after curing and hardening to produce a water permeable porous body. In the production, there are cases where sand of uniform particle diameters is used, where epoxy resin is used as an adhesive and where the mixed weight of the adhesive to that of sand ratios are 2-13%.
