由于船只和其它水上交通工具通过船闸时产生涌浪,致使墙体受到冲刷,墙表面混凝土剥落。若采用传统的混凝土开挖方法修补不仅耗资大,而且需要长时间关闸停航,其经济损失严重。美国陆军工程师兵团采用一种较为实用的修补下莫纽门特尔坝船闸闸墙的方法,即在闸墙上喷射乳胶玻璃纤维混凝土薄层,与传统方法相比,新法具有省时、省工和省料的特点。 As the ship and other water vehicles are swept through the ship lock, the wall is washed away and the concrete on the wall surface is peeled off. If the traditional method of concrete excavation repair is not only costly, but also requires a long time to shut down the gate, the serious economic losses. The US Army Corps of Engineers adopted a more practical method of repairing the sluice gate of the Maunemonte Dam, that is, spraying a thin layer of latex fiberglass concrete on the sluice gate. Compared with the traditional method, the new method has the advantages of saving time and labor And the characteristics of the material.
