Summary:PROBLEM TO BE SOLVED: To develop a laser level tripod for slope face accurately performing excavating and shaping works by means of an excavation support device mounted on a backhoe, by causing a rotary laser device to project light parallel to a slope face, in a slope face shaping work of civil-engineering and construction engineering works.SOLUTION: The surveying tripod for mounting a laser projection device, rotationally radiating a laser light beam includes a level device for grasping the inclination slope in one direction and a level device for grasping the level, in a direction orthogonal to the direction at one end part of a plate-shaped base table for mounting the laser projection device. A collimation telescope is installed on a plate-shaped mount base, extending upward from the other end part of the base table and provided parallel to the base table. The laser level tripod for slope face capable of predicting and adjusting the position of a laser light projection line with the collimation telescope is used to perform laser light projection and slope-surface shaping.
