Description
Technical Field
The utility model relates to a ground settlement monitoring technology field especially relates to a measure sign and observation system.
Background
In tunnel engineering, in order to monitor the ground settlement problem which may occur in a tunnel, a vertical settlement monitoring control net is often established for ground settlement monitoring. The stability of the vertical settlement monitoring control network can monitor target measuring points (hereinafter referred to as "target measuring points") of the vertical settlement monitoring control network by methods such as leveling measurement, photoelectric ranging triangulation elevation measurement or static leveling measurement.
When the total station is adopted to monitor the settlement change of a target measuring point, the total station sends out an optical signal to prism equipment placed at the target measuring point, receives the optical signal reflected from the prism equipment, calculates data such as the distance or three-dimensional coordinates between the prism equipment and the total station by calculating phase shift generated by the back-and-forth optical signal, and further can obtain position information such as a horizontal angle, a vertical angle, a distance (an oblique distance, a horizontal distance), a height difference and the like, and in the whole construction process, whether a building at the position has displacement or settlement deformation is judged by continuously monitoring the position information of the same target measuring point.
When the level gauge is used for monitoring the sedimentation change of the target measuring point, the level gauge is directly used for measuring the horizontal position of the leveling marker placed at the target measuring point, and the sedimentation deformation information of the target measuring point can be obtained.
However, because the spatial positions cannot be overlapped, an observation point of the total station (i.e., prism equipment at the target measuring point) and an observation point of the level (i.e., a leveling marker at the target measuring point) cannot be completely overlapped, so that the datum of data measured by the total station and the datum of data measured by the level are not identical, and further, the ground settlement analysis based on the data observed by the total station and the level together lacks of rigidness.
SUMMERY OF THE UTILITY MODEL
Therefore, a need exists for a measurement identifier and observation system, which aims to solve the problem that ground settlement analysis based on the common observation data of a total station and a level lacks rigor because the observation point of the total station and the observation point of the level cannot be completely superposed when the total station and the level are used for observing the same target measurement point.
The application provides a measurement identifier, including:
the level detection piece is used as an observation point of the level;
the prism is used as an observation point of the total station, the level detection piece is connected with the prism, and the level detection piece and the prism are distributed along the height direction of the measurement mark.
When the measuring mark is used for monitoring ground settlement, the measuring mark is placed at a target measuring point, a total station instrument is used for sending optical signals to a prism placed at the measuring mark and receiving the optical signals reflected from the prism, data such as the distance or three-dimensional coordinates between the prism and the total station instrument are calculated by calculating phase shift generated by the back-and-forth optical signals, and then position information such as a horizontal angle, a vertical angle, an oblique distance, a horizontal distance, a settlement height difference and the like at the target measuring point is calculated; and meanwhile, a leveling instrument is used for directly observing the leveling member of the measurement mark to obtain information such as the settlement height difference of the target measuring point.
Because the level detection piece is connected with the prism, and the level detection piece and the prism are distributed along the height direction of the measuring mark, when the ground subsides, the subsidence height difference of the level detection piece along the height direction of the measuring mark is consistent with the subsidence height difference of the prism along the height direction of the measuring mark, if the subsidence height difference obtained by the total station observation prism is consistent with the subsidence height difference obtained by the level observation detection piece, the total station and the level check are consistent, the data measured by the total station and the data measured by the level can be considered to be obtained based on the same observation point, and therefore, the reliability and the rigidness of the subsidence data observed by the total station and the level are ensured;
if the settlement height difference obtained by the observation prism of the total station is inconsistent with the settlement height difference obtained by the leveling instrument observation level detection piece, the total station and the leveling instrument do not pass the verification, the data measured by the total station and the data measured by the leveling instrument cannot be considered to be obtained based on the same observation point, and at the moment, the total station and the leveling instrument need to be checked and adjusted until the settlement height difference obtained by the observation prism of the total station is consistent with the settlement height difference obtained by the leveling instrument observation level detection piece. So, through using this survey mark, can solve among the traditional measurement scheme because the observation point position of total powerstation and the observation point position of spirit level can't coincide completely, lead to the ground settlement analysis based on the data that total powerstation and spirit level observed jointly to lack the problem of rigor.

In an embodiment, a measurement mark 10, please refer to fig. 1, includes a level detecting member 100 and a prism 200, wherein the level detecting member 100 is used as an observation point of a level gauge; the prism 200 is used as an observation point of the total station, the level detecting member 100 is connected to the prism 200, and the level detecting member 100 and the prism 200 are distributed along a height direction (for example, an H direction shown in fig. 1) of the measurement indicator 10.
When the measuring mark 10 is used for ground settlement monitoring, the measuring mark 10 is placed at a target measuring point, a total station is used for sending an optical signal to a prism 200 placed on the measuring mark 10 and receiving the optical signal reflected from the prism 200, data such as the distance between the prism 200 and the total station or three-dimensional coordinates are calculated by calculating the phase shift generated by the back and forth optical signal, and then position information such as a horizontal angle, a vertical angle, an oblique distance, a flat distance, a settlement height difference and the like at the target measuring point is calculated; meanwhile, a leveling instrument is used for directly observing the leveling member of the measuring mark 10 to obtain information such as the settlement height difference of the target measuring point.
Because the level detection piece 100 is connected with the prism 200, and the level detection piece 100 and the prism 200 are distributed along the height direction of the measuring mark 10, when the ground surface is settled, the settlement height difference of the level detection piece 100 along the height direction of the measuring mark 10 is consistent with the settlement height difference of the prism 200 along the height direction of the measuring mark 10, if the settlement height difference obtained by observing the prism 200 by the total station is consistent with the settlement height difference obtained by observing the level detection piece 100 by the level, the total station and the level are checked to be consistent, the data measured by the total station and the data measured by the level can be considered to be obtained based on the same observation point, so that the reliability and the rigidness of the settlement data jointly observed by the total station and the level are ensured;
if the settlement height difference obtained by the total station observation prism 200 is inconsistent with the settlement height difference obtained by the level observation and level detection piece 100, it indicates that the total station and the level do not pass the verification, and it cannot be considered that the data measured by the total station and the data measured by the level are obtained based on the same observation point, and at this time, the total station and the level need to be checked and adjusted until the settlement height difference obtained by the total station observation prism 200 is consistent with the settlement height difference obtained by the level observation and level detection piece 100. Therefore, by using the measuring mark 10, the problem that the ground settlement analysis based on the data observed by the total station and the level instrument together is lack of rigor due to the fact that the observation point of the total station and the observation point of the level instrument cannot be completely coincided in the traditional measuring scheme can be solved.

The static level sensor 300 generally utilizes acquisition software to realize automatic acquisition, storage and uploading of data, namely the static level sensor 300 can automatically detect, and the level is usually manually detected, and by introducing two sets of level detection systems, the numerical value measured by the static level sensor 300 and the numerical value measured by the level are checked and compared with each other, so that the accuracy and reliability of the level for measuring the settlement height difference can be further improved.
In the actual observation process, if the settlement height difference obtained by the total station observation prism 200, the settlement height difference obtained by the level gauge observation level detection part 100 and the settlement height difference measured by the static level sensor 300 are completely consistent, the total station, the level gauge and the static level sensor 300 are checked to be consistent, data measured by the total station, data measured by the level gauge and data measured by the static level sensor 300 can be considered to be obtained based on the same observation point, and the reliability and the rigor of the settlement data measured by the combination of the total station, the level gauge and the static level sensor 300 can be ensured;
if the settlement elevation difference obtained by the total station observation prism 200, the settlement elevation difference obtained by the level observation and level detection piece 100 and the settlement elevation difference measured by the hydrostatic level sensor 300 are not completely consistent, the total station and the level are checked to fail with the hydrostatic level sensor 300, and at the moment, the total station and the level need to be checked and adjusted until the settlement elevation difference obtained by the total station observation prism 200, the settlement elevation difference obtained by the level observation and level detection piece 100 and the settlement elevation difference measured by the hydrostatic level sensor 300 are consistent.
