[0002] Subway stations are built in fixed areas, with a construction period of 2 to 3 years. Most of the construction machinery and equipment are located around the stations, and the operations are relatively concentrated, which can easily cause visual obstructions to construction measurements. The machinery and equipment have to be moved, or the measurement work can only be carried out after the construction of the machinery and equipment is completed, which affects construction production. At the same time, the measurement efficiency is not high.

[0003] After searching, the patent authorization announcement number CN 215717585 U discloses an observation platform for subway station construction measurement, "including: a pipe column, the lower part of the pipe column is buried in the ground; a bracket, the lower part of the bracket is buried in the ground, the bracket is arranged around the outer periphery of the pipe column, and the upper part of the bracket is provided with a measuring work platform; a stabilizing support ring, fixed on the bracket and fixedly connected to the pipe column; a staircase, one end of which is arranged on the ground and the other end is connected to the measuring work platform." The guardrails or brackets arranged around the above-mentioned observation platform, the four columns of the bracket will block the observation of the measuring instrument during the measurement process. When the line of sight of the measuring instrument is blocked, the position of the measuring instrument needs to be readjusted, and it needs to be re-leveled and re-centered, which will make the measurement time-consuming and labor-intensive, and inefficient.
