THE GROUTING SPECIFICATION FOR SOIL REINFORCEMENT USE OF ION EXCHANGE COPOLYMER

摘要

PURPOSE: A grouting method for the soil reinforcement using an ion exchange copolymer is provided to secure the tight soil quality and the large compacting factor, and to improve the soft ground reinforcing efficiency by increasing the insertion amount of cement paste. CONSTITUTION: A grouting method for the soil reinforcement using an ion exchange copolymer comprises the following steps: punching an injection hole to the ground by spraying high pressure water form an injection rod(430); elevating the injection rod from the lower side of the injection hole, and spraying compound solution including an ionization polymer(450); curing the ground for 24~48 hours(470); spraying cement paste and air along to the injection hole, and grouting(490).
