全省目前正进行20世纪50～70年代修建的大中型水库的除险加固和大中型灌区续建配套与节水改造工程,对已建水工混凝土建筑物进行各种老化加固处理是主要内容之一,即解决各种原因造成的裂缝和表面剥蚀、水质侵蚀、冲磨、空蚀、钢筋锈蚀、混凝土质量差等老化问题。本文以鲇鱼山灌区西干渠1~#、2~#渡槽防渗处理工程建设、运行的实际情况为例,介绍了丙乳砂浆,它是一种具有优异的抗渗性、抗腐蚀性、抗冻融性、粘结力极强的工程修补施工材料,值得广泛推广。
The province is currently carrying out the reinforcement of large and medium-sized reservoirs built in the 1950s-1970s and the reconstruction and water-saving reconstruction projects of large and medium-sized irrigation districts, and various aging and strengthening treatment of the existing hydraulic concrete structures are the main contents First, to solve the various causes of cracks and surface erosion, water erosion, erosion, cavitation erosion, steel corrosion, poor quality concrete and other aging problems. In this paper, the actual situation of seepage control engineering construction and operation of 1 ~ # and 2 ~ # aqueducts of West Main Canal of the Bayuishan Irrigation District is taken as an example to introduce the mortar of acrylic mortar, which is a kind of mortar with excellent impermeability, corrosion resistance, Anti-freeze-thaw, strong adhesion of engineering repair construction materials, it is worth widely disseminated.
