Concrete bench mark monument for mounting displacement sensor and elevation observing and calculating method thereof

Abstract

The invention discloses a concrete bench mark monument for mounting a displacement sensor and an elevation observing and calculating method thereof. The displacement sensor is arranged in the conventional concrete bench mark monument, and is connected with a drill hole anchoring end with a certain design depth through a connecting rod. When the concrete bench mark monument on the earth surface sinks, the sensor is driven to be deformed synchronously, readings of the sensor at each observing time interval are recorded through a portable reading instrument, sinking deformation of the bench mark monument relative to the anchoring end is calculated, and working starting point elevations of the bench mark monument at each observing time interval are calculated according to a connection surveying result obtained after connection surveying with a datum mark. By adopting the concrete bench mark monument, the problem of working starting point elevation observation of the bench mark monument at each observing time interval in a connection surveying period is solved, the working base point accuracy of the conventional concrete bench mark monument is increased, and working reference point and reference point connection surveying times of the bench mark monument are reduced; the concrete bench mark monument can be widely applied to settlement measurement work of engineering foundations, bases, upper structure and sites in industrial and civil buildings, municipal traffic, hydraulic engineering and the like.

Description

technical field [0001] The invention relates to a concrete leveling stone, in particular to a concrete leveling stone equipped with a displacement sensor and an elevation observation and calculation method thereof. Background technique [0002] In industrial and civil buildings, municipal transportation, water conservancy and other projects, it is necessary to bury the leveling work base point in the foundation, foundation, superstructure and site settlement measurement work. Due to the limitation of the site conditions of the project site, the traditional concrete basic leveling stone work base point cannot be buried in a stable undisturbed soil layer; in addition, factors such as the natural surface settlement of the project area, the drop of groundwater level in the project area, and rainfall all affect the traditional work. Base point accuracy. In order to eliminate the influence of the above factors, it is necessary to conduct joint measurement of the high-level refere...
