Abstract

The invention relates to the technical field of mounting and construction measuring and provides a two-dimensional spacing and dislocation measuring tape. The two-dimensional spacing and dislocation measuring tape comprises a positioning unit and a measuring unit, wherein the positioning unit comprises a leveling part, a blocking part and a connecting frame connecting the leveling part with the blocking part; the measuring unit comprises a spacing tape and a measuring tape saddle which can slide along the spacing tape, and is fixed through a saddle lock; a dislocation tape is connected to the measuring tape saddle, the dislocation tape can move in a self-measuring direction, and is fixed through a dislocation tape lock; the measuring direction of the dislocation tape is perpendicular to a leveling plane of the leveling part; one end, provided with the blocking part, of the connecting frame is connected with the spacing tape. The measuring tape can realize purposes of measuring relative spacing and dislocation of two structures at the same time, is simple to operate, can control the measuring errors within 0.01 m, can be applied to underground mounting construction projects of large structures of an immersed tube, an immersed tank, and the like, and can realize purposes of convenient underwater measuring operation and accurate data.

Description

technical field

[0001] The invention relates to the technical field of installation and construction measurement, in particular to a two-dimensional measuring ruler for spaced teeth, and more specifically, a two-dimensional measuring ruler for spaced teeth installed underwater with a large-scale structure. Background technique

[0002] During the underwater installation of large-scale structures such as immersed tubes and caissons, since it is necessary to control the underwater relative position of the newly installed structure and the installed structure, it is necessary to use the measurement and control system to guide the newly installed structure to the design position. Make the installation accuracy meet the design requirements. Among them, the measurement and control system includes GPS on the surface, sonar in the water, cable units, and underwater diving measurement tools. The existing conventional tool for diving measurement is a straightedge. Once the relative s...
