Friction reducing coating for engineering works, and, sheet pile, steel tubular pipe and construction method

摘要

The present invention has its object to provide a friction reducing coating for engineering works, and, a soil adhesion-preventing sheet pile or steel tubular pipe wherein the above-mentioned friction reducing coating for engineering works applied thereto in advance, and, a soil adhesion-preventing construction method which comprises using the above-mentioned friction reducing coating for engineering works and/or the above-mentioned soil adhesion-preventing sheet pile or steel tubular pipe and further provide a negative friction cut construction method for foundation structures which comprises using the above friction reducing coating for engineering works and thus can cut the friction between a foundation structure after laying underground and the surrounding ground and reduce the influences of changes in the surrounding ground on the foundation structure as well as a caisson or pipe jacking construction method which comprises using the above friction reducing coating for engineering works and can reduce the friction between the substrate and soil while minimizing the influences on the surrounding ground and thus can markedly improve the speed and efficiency of construction work. A friction reducing coating for engineering works comprising a water-absorbing resin (a), a hydrophilic binder resin (b) and a solvent (c) as essential components, wherein said hydrophilic binder resin (b) has an acid value of 40 mg KOH/g to 500 mg KOH/g.
