在钢闸门中,常见的是腐蚀问题。由于水利水电工程的热属性,从而导致钢闸门以及启闭机受到海水的侵蚀,尤其是运行几十年以上的闸门,尽管也进行了相关的维护以及报验,在表面进行防锈喷锌的措施,但是由于运行时间过长,不可避免的存在着钢闸门以及启闭机的腐蚀现象。在对钢闸门以及启闭机进行检查过程中,存在锈斑、锈皮叠起以及锈坑等问州苗木 保定通风管道 丝网立柱模具 尼龙输送带 保定防水 保定空压机 高碑店养老院题,其中很多构件的有着很深的锈坑,严重的甚至出现孔洞。变形也是钢闸门存在的质量问题,由于钢闸门的变形腐蚀,导致钢结构构件的应力分布出现变化,降低了钢闸门整体结构的刚度以及强度,最终减少了闸门的使用寿命。
In the steel gate, the most common problem is corrosion. Due to the thermal properties of water conservancy and hydropower projects, the steel gate and hoist are eroded by seawater, especially the gate that has been operated for more than decades. Although relevant maintenance and inspection have been carried out, and anti rust and zinc spraying measures have been taken on the surface, due to the long operation time, the corrosion of steel gate and hoist is inevitable. During the inspection of the steel gate and hoist, there are problems such as rust spots, rust skin stacking and rust pits. Many of the components have deep rust pits, and even holes. Deformation is also a quality problem of the steel gate. Due to the deformation and corrosion of the steel gate, the stress distribution of the steel structure components changes, which reduces the stiffness and strength of the overall structure of the steel gate, and finally reduces the service life of the gate
