Abstract
A polymer grouting method for uplifting a ballastless track of a high-speed rail includes following steps of: (1) drilling grouting holes; (2) manufacturing geo-textile bags and binding the grouting pipes up with the geo-textile bags; (3) tying up the geo-textile bags; (4) displacing the geo-textile bags; (5) grouting two-component expansive polymer materials into the geo-textile bags; (6) uplifting the track; (7) grouting two-component expansive polymer materials for filling; and (8) monitoring amount of the uplifting, wherein a vertically uplifting height is monitored in real time by a laser level, and the grouting is quit if the vertically uplifting height meets uplifting requirements.
