ANTICLOGGING METHOD OF UNDERDRAINAGE PIPE

摘要

PROBLEM TO BE SOLVED: To add an anticlogging function preventing the disposition of iron oxides into an underdrainage pipe in advance. SOLUTION: In the anticlogging method of an underdrainage pipe, drainage including iron is neutralized and the iron is removed by embedding an anticlogging material prepared by mixing a granular rockwool forming high calcium silicate-contained material having excellent water permeability and a contact property with an inorganic hgydraulic material, and the propagation of iron oxidation bacteria in the inside and the peripheral part of the underdrainage is depressed, and iron oxides are prevented from being disposed in the underdrainage pipe.
