用塑料油膏作为止水材料,解决渡槽接缝止水问题,已见报导。文[1]中介绍了塑料油膏的热灌法,即将顶热熔化后的油膏往缝内浇灌的施工方法(同样的施工方法也见于文[2])。一般来说,只要接缝规则、结构型式合理、缝口内外壁堵塞得当,热灌法的止水效果是可靠的。但对大量已建渡槽接缝止水的处理,采用热灌法则 Plastic grease as a water stop material to solve the aqueduct sealing water problems have been reported. In [1], the hot filling method of plastic ointment is introduced, that is, the method of applying ointment to the seam after top hot melt (the same construction method is also found in [2]). In general, as long as the rules of joints, the structure of a reasonable style, plug the wall inside and outside the wall properly blocked, hot water irrigation effect is reliable. However, a large number of aqueduct seams have been treated with water stop, using hot-fill rule
