A construction method of an FRP impervious wall structure is provided to cut down on the cost of construction, to shorten a period of construction and to reduce dangerous elements in a construction site by constructing an impervious wall with FRP panels and grout. A construction method of an FRP impervious wall structure(21) comprises the steps of: manufacturing an FRP panel box(15) by attaching horizontal and vertical FRP flanges to the circumference of a FRP panel and fastening the FRP flange panels in horizontal and vertical directions by bolts and nuts, and piling up FRP on the inside; installing the FRP panel box not to have a gap from the lower part of a seepage line(14) up to an excavation line by piling up first FRP on a part where the FRP flange panels meet an underground structure and fixing with knife blocks(19) at regular intervals, and then piling up second FRP; re-filling the whole excavated part with soil; and injecting cement paste into the FRP panel box using a grouting device. |
