Abstract:In China′s seasonal frozen soil region, frost heaving damage of anti-seepage lining canal is the great harm to the water conveyance project. A new material polyurethane insulation board laying under the channel concrete lining is used to solve the south main canal frost heaving damage problem in Linhe district of Inner Mongolia. Through conducting the site test, the changing rules and features of the ground temperature, frozen depth, water content and frost heaving amount for this kind of insulation boards located on the different slope positions and the board thicknesses are analyzed. Insulation anti-freezing effect under different schemes was summarized. The results show that laying the 3-cm-thick polyurethane insulation board up the slope, the 4-cm-thick polyurethane insulation board below the slope, the 4-cm-thick polyurethane insulation board up the yin slope, the 5-cm-thick polyurethane insulation board below the yin slope can ensure that the canal concrete lining is intact in this area. It also provides the technical support of heat preservation material for subsequent rigid lining channels.
