Abstract
A grouting method for anchoring with polymer is provided, wherein the method includes steps of: a) rod body processing; b) tying up a geotextile bag and grouting tubes on the anchoring rod body; c) hole drilling; d) polymer grouting: I. hole sealing grouting; II. anchoring grouting. The present invention has advantages of a sufficient adaptability, non-water reaction, convenient and fast construction, being economic, a high strength and a high durability. An expansive polymer material has an obvious compacting effect on soil, and is capable of increasing a friction force between a grout and a base; the water-proofing polymer material is an impermeable material for a steel rod body, and is of benefit to anti-corrosion and durability of the rod body; a solidifying time of the polymer material is short and no maintenance is needed in such a manner that construction periods are shortened.
