以下四项,()不是闸门及其埋件需要清洁养护的原因。
A.
各种闸门均安装在露天,门叶的格梁、弧形闸门的支臂等部位往往可能由于排水堵塞等原因而存在积水或泥沙淤积物等,在空气和阳光的共同作用下,积水或泥沙积存处容易造成漆膜的破坏和金属结构的腐蚀。
B.
深运行的大型平面闸门排水不畅还会增加闸门的启闭荷载,增加闸门维护清理的工作量和工作难度,在多泥沙的河流,深闸门提出水面,格往往积存大量泥沙,必须及时进行人工清洗和疏通。
C.
将闸门上的落水堵塞,不及时清理和疏通,将影响闸门的清洁、美观,严重会加速闸门的锈蚀,不便检查闸门存在的缺陷,如保护层脱落、锈蚀状况、有无焊缝开裂、有无被撞击破损等情况。
D.
闸门门叶、支臂杆、支铰、吊耳、止水及其埋件表面清洁,止水橡皮的压板固定的螺栓、螺丝松动应紧固,行走支承及支铰等转动部位润滑油补充或更换,止水橡皮的压缩量调整。
