摘　　要：本文通过对 ３０１国道哈尔滨－阿城（刘秀屯）段改造项目 ６７２处路面板下和 ２０座桥头搭板及明涵台背下脱空的封堵治理施工．综合分析研究了灌浆封堵方法治理权下脱空问题．达到充实板底、加固基层、增强支撑、防止地表水入渗冲刷。使之均匀传递荷载的目的．从而大大延长刚性路面的使用寿命。通过室内、现场试验与施工研究。提出板下脱空的检测方法。浆的配合比及施工艺。Based on the construction of the filling voids beneath of 20 bridges and 672 pavements in the national highway No. 301(Liuxin village. Harbin-archeng). the paper has analyzed disposition of under-plate voids by means of grouting filling.filling for the prupose of substantiating plate bottom. strengthing subgrade. reinforcing strut. preventing pen etration and wash of surface water. transmiting load evenly. so that use-life of rigid pavement can be increased greatly. By indoor and field test and construction research. test method. mortar mix proportion and construction art of voids of plate bottom are brought up.
