Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering safety monitoring, and more specifically to a simple surface deformation comprehensive monitoring device. Background Art

[0002] In the field of safety monitoring engineering, especially in the application of slope surface deformation monitoring in hydropower stations, concrete observation piers are cast on the slope surface, forced centering bases are arranged, and the intersection method or polar coordinate method is used to monitor the horizontal displacement of the slope surface; while the vertical displacement monitoring of the slope surface is mainly divided into two types: one is to use the prism on the top of the concrete observation pier and use trigonometric height measurement, which has low observation accuracy; the other is to arrange leveling points on the base of the concrete observation pier and use the tight leveling method for measurement.

[0003] The mandatory centering plate is used in a wide range of surveying and mapping fields, such as land and resources survey, survey and demarcation, topographic mapping, reservoir dams, highway bridges, equipment installation, civil buildings, industrial buildings, earthquake monitoring, deformation monitoring and other surveying and mapping projects. As a permanent or temporary survey mark, the mandatory centering plate often provides a mandatory centering connection for various total stations, theodolites, rangefinders, levels, GPS and other measuring instruments and equipment.

[0004] When monitoring the surface deformation of the slope of a hydropower station, a forced centering plate is also needed. Due to work requirements, the forced centering plate needs to be set on the top of the dam. Due to the lack of protective measures for the forced centering plate and the influence of the on-site environment, the forced centering plate will easily rust and age. Once the forced centering plate rusts and ages, it will affect its normal use in the later period, resulting in a decrease in monitoring accuracy. Utility Model Content

Accordingly, the six baffles 7 can be assembled together to cooperate with the bottom plate 2 and the top plate 8 to protect the forced centering disk 4, thereby achieving the purpose of extending the service life of the forced centering disk 4.

[0027] Furthermore, a slide plate 11 is fixedly connected to one side of the baffle plate 7, and a slide groove 12 is opened on the other side of the baffle plate 7. The slide groove 12 is used in conjunction with the slide plate 11. The slide plate 11 on one baffle plate 7 is placed in the slide groove 12 on the other baffle plate 7. The slide plate 11 can slide in the slide groove 12, and the slide plate 11 and the slide groove 12 are tightly fitted, thereby enhancing the sealing between the two adjacent baffle plates 7.
