る。In recent years, as a method of positioning such a pipe, for example, as shown in a vertical side view of FIG. 3, a laser device 2 for emitting a laser beam is arranged at one end of the pipe body 1 to make the inside of the pipe body 1. A method of emitting a laser beam B to a target 3 provided at the other end of the laser beam and detecting the presence or absence of a positional deviation based on the presence or absence of a deviation of the laser beam B from the target 3 is drawing attention.

介して載置されるIn this pipe positioning method, the laser device 2 is provided with a main body 2a and at least three legs 2b projecting from the main body 2a, as shown in FIG. 3 and FIG. Mounted directly on the bottom of the surface or through a bracket

要がある。Further, in this pipe positioning method, the backfilling sand 5 around the pipe body 1 is tamped by the tamping machine 4 such as a vibro plate or a tamping rammer at the time of backfilling. When the vibration of the compacting machine 4 is transmitted to the laser device 2, the laser device 2 resonates and the position of the laser device 2 may shift. Therefore, in order to prevent such a positional shift, the laser device 2 is placed inside the tube body 1. Need to be fixed.

る。For this reason, conventionally, as shown in the front view of FIG. 4, the fixing metal fitting 6 inserted between the upper portion of the inner peripheral surface of the tube body 1 and the main body 2a is extended to extend the inner peripheral surface of the tube body 1. The main body 2a is fixed so as not to move in the tubular body 1.

And a cap nut 6c screwed into the cap nut from above and a handle 6d for rotating the cap nut 6c. The cap nut 6c is rotated in the screwing direction to increase the distance from the mounting frame 6a. As a result, the head of the cap nut 6c is pressed against the upper portion of the inner peripheral surface of the tube body 1 to replenish the gap between the upper portion of the inner peripheral surface of the tube body 1 and the main body 2a.

作用が失われるという問題がある。By the way, the natural frequencies of the tube body 1 and the laser device 2 are not usually the same, and the resonance frequency with respect to the vibration of the compacting machine 4 is naturally different. Therefore, relative vibration occurs between the tube body 1 and the laser device 2, and this vibration causes a fluctuating load in which the contact pressure of the fixing metal fitting 6 to the inner peripheral surface of the tube body 1 is repeatedly changed. There is a problem that the inner peripheral surface of the tube body 1 which is not crushed is broken and a gap is generated between the fixing metal fitting 6 and the inner peripheral surface of the tube body 1, so that the fixing action is lost.
