Description

Technical Field

[0001] The utility model relates to the technical field of shield machine excavation, in particular to a shield machine excavation parameter optimization device when a subway shield tunnel passes under a building. Background Art

[0002] When tunneling, the shield machine needs to use equipment to detect and optimize parameters. The total station, that is, a total station electronic distance meter, is a high-tech measuring instrument that integrates optics, mechanics, and electronics. It is a surveying and mapping instrument system that integrates horizontal angle, vertical angle, distance (slant distance, horizontal distance), and height difference measurement functions.

[0003] The existing Chinese utility model patent with reference number CN208588378U discloses a total station, which relates to the field of surveying instruments and includes a total station body and a tripod. The tripod includes a support base and three legs rotatably connected to the bottom of the support base. A spherical receiving groove is provided at the center position below the support base. A gravity ball rotates in the receiving groove. The lower end of the gravity ball protrudes from the lower end of the receiving groove. The gravity ball includes an upper hemisphere and a lower hemisphere. A counterweight is fixed in the lower hemisphere. A vertically arranged laser is fixedly connected to the middle of the lower hemisphere. A light hole is opened at the lower end of the lower hemisphere corresponding to the position of the laser. A reference plate is also fixedly connected horizontally to the lower end of the support base. The reference plate has a reference hole vertically opened corresponding to the center position of the support base. The invention solves the problem in the prior art that it is impossible to visually observe whether the total station body is in a horizontal state on the tripod. After the total station is placed on the ground, it is convenient to determine whether the total station body is in a horizontal state, which is convenient for adjustment.

[0004] When optimizing the tunneling parameters of a shield machine, a total station is required for detection. However, the existing total station is used outdoors for a long time, and the measuring mirror is easily affected by dust accumulation and adsorption, thereby affecting the detection effect and the detection parameters.
