[0002] A high pier refers to a pier with a height greater than or equal to 40 meters. It is supported by high piers in viaducts or bridges. During construction work on the high piers, a construction platform is installed outside the high pier, and then a fence is installed at the edge of the construction platform to prevent people on the construction platform from falling and causing danger during the construction process.

[0003] In the prior art, the protective fence for working on the edge of high piers is installed on the construction platform. The width of the fence is consistent with the length of the outer edge of the construction platform, so as to prevent people from falling from the edge of the construction platform. However, some construction platforms are larger in size. In this case, the width of the fence is smaller than the length of the outer edge of the construction platform, and it is necessary to replace the fence with other width sizes. In this way, it is necessary to prepare multiple fences of different width sizes, which not only increases the cost of use, but also reduces the applicability of the fence. For this reason, we propose a protective fence for working on the edge of high piers. Utility Model Content
