Adjacent hydrostatic levels 1 are connected by a pipeline 3, and the pipeline 3 can conduct the pressure of the working fluid, so that the hydrostatic level 1 can detect the height difference between the hydrostatic level 1 and the adjacent hydrostatic level 1. CP III control points 2 are symmetrically distributed on two sides of the track 4, and connecting parts for the static level 1 are arranged on the CP III control points 2. During measurement, each hydrostatic level 1 is mounted on the CP iii control points 2 to measure the elevation between the CP iii control points 2.

During the measurement using the hydrostatic level 1, the insertion rod 6 of the hydrostatic level 1 is inserted into the mounting hole 5. CP III control point 2 may use the existing CP III control points on both sides of track 4. The elevation calculation point of the hydrostatic level 1 is the same as that of a conventional CP III measuring benchmark, so that the elevation obtained by measurement of the hydrostatic level 1 and the existing CP III elevation are a unified datum plane, and the measurement result of the hydrostatic level 1 can be calculated and linked with the measurement result of a conventional measurement method.
