经水压试验发现渗漏的各种钢筋混凝土管,如果其微孔直径小于350～400微米,可用压力灌注各种胶质组分的方法堵塞其孔隙,以恢复它的抗渗性。图1为管子的抗渗性能与混凝土孔隙直
All kinds of reinforced concrete pipes that have leaked through the hydraulic test are found to have pores that can be filled with pressure by injecting various colloidal components in order to restore its impermeability if its pore diameter is less than 350-400 microns. Figure 1 shows the impermeability of pipes and the straightness of concrete
