摘　　要：水闸闸墩表面混凝土由于长期受高速含沙水流的冲刷会出现不同程度的磨损、缺失、漏筋现象,对水工结构安全影响很大,采用性能优越的抗冲耐磨材料修复和防护尤为重要。通过对聚脲材料性能分析介绍三河闸闸墩防护施工过程,经过检测试验和水流冲刷考验,证实聚脲材料具有优越的附着力、抗耐磨性、抗耐冲性,对类似水闸混凝土防护具有借鉴意义。Due to the long-term erosion of high-speed sediment laden flow,the surface concrete of sluice pier will have different degrees of wear,loss and leakage of reinforcement,which has a great impact on the safety of hydraulic structure.It is particularly important to repair and protect the surface concrete of sluice pier with superior anti erosion and wear-resistant materials.Through the performance analysis of polyurea material,this paper introduces the construction process in the protection of Sanhe Sluice Pier.Through the test and water scouring test,it is proved that polyurea material has superior adhesion,wear resistance and impact resistance,which can be used for reference for concrete protection of similar sluice.
