虽然砼具有较高的强度,较好的耐老化等优点,但是经过长期的运行使用,在荷载、温度变化或不均匀沉降变形等因素的影响下,经常会在砼强度较低的局部产生裂缝,水工砼裂缝在受高速水流冲击的部位如输水管道、涵洞、导虹管、溢洪道等设施中比较常见,这些裂缝如发展严重,会影响工程的正常使用,严重者会影响建筑物的安全,因此,应及时采取相应的处理措施进行修补。常用的修补方 Although concrete has the advantages of higher strength, better anti-aging, etc., after long-term operation and use, under the influence of load, temperature variation or uneven settlement and deformation and other factors, cracks often occur in areas with low concrete strength , Hydraulic concrete cracks in the parts affected by high-speed currents such as water pipelines, culverts, leading Hong Guan, spillway and other facilities are more common, such as the serious development of these cracks will affect the normal use of the project, in serious cases will affect the building Therefore, we should promptly take the appropriate measures to repair.
