It is very important to maintain the manhole cover, because the manhole cover exists on the ground that we pass through every day. If there is any problem, it may cause casualties, so we must do a good job in the maintenance of the manhole cover.
First of all, we must consider from the perspective of the masses that Xushui manhole covers are public goods, so many people may not have the concept of maintenance, and even criminals steal the manhole covers to sell money. These are situations that need to be considered. Secondly, from workers From the perspective, they need to carry out maintenance work regularly, not only to check whether it is damaged, but also to test whether its bearing pressure has changed. Also, when it rains, the manhole cover is easy to rust, so it is also necessary to perform rust removal work. Here I would like to remind everyone that although Xu Shuijing covers are public goods, they are also an indispensable part of our lives. If everyone has such a concept of protection, the probability of manhole cover damage will be greatly reduced.
