Background
In the field of dam monitoring, monitoring points need to be measured by using total stations for a long time, and most of the measuring points are distributed on near-dam reservoir sides and side slopes on two sides of a dam, so that more measuring points are distributed in a wider area. If the prism is newly erected during each measurement, the measurement efficiency is low, and more operators are required to put the prism in place. If the prism is erected in the field for a long time without protective measures, the prism is easy to be interfered by external factors such as wind, animals and the like. The side slope displacement monitoring points are limited by terrain conditions and construction conditions, the specification and the size are not completely unified, and the traditional prism protection device cannot be suitable for various prism measuring point piers.
Therefore, a general prism fixing and protecting device for long-term monitoring is needed, which is applicable to both standard and nonstandard side slope measuring piers, and meanwhile, the carrying of tools is reduced as much as possible due to higher and dangerous side slope features during daily maintenance.
