出于方便施工等因素的考虑 ,采取正置方式预制混凝土U型簿壳渡槽是现实中常用的办法 ,但由于槽身底部不易捣实而往往留下隐患 ,最终造成保护层乃至更深层的混凝土开裂、脱落和钢筋生锈 ,因而危及渡槽安全。采用环氧树脂砂浆和环氧树脂混凝土填补 ,既具有较好的粘结性 ,又具有补强作用 ,可以一试。 For convenience of construction and other factors, the precast concrete prefabricated U-shaped prefabricated aqueduct is a commonly used method in reality, but due to the bottom of the groove is not easy to tamping and often leave hidden dangers, eventually resulting in protective layer and even deeper concrete Cracking, falling off and steel rusting, thus endangering aqueduct safety. Epoxy resin mortar and epoxy resin to fill, both with good adhesion, but also has the reinforcing effect, you can try.
