PROBLEM TO BE SOLVED: To provide a practical displacement measurement device of a wastewater treatment pit, which exerts an unconventional action effect, a clod movement monitoring method, and a wastewater treatment pit monitoring method.;SOLUTION: A displacement measurement device of a wastewater treatment pit includes: a first distance measurement part 2 which applies a laser beam to a second reference portion P2 facing a diameter direction from a first reference portion P1 on an inner wall surface of a wastewater treatment pit 21, so as to measure the distance between the first reference portion P1 and the second reference portion P2; a second distance measurement part 3 which is provided in a manner to apply the laser beam in a direction intersecting with the laser beam applied by the first distance measurement part 2, and which applies the laser beam to a fourth reference portion P4 facing the diameter direction from a third reference portion P3 on the inner wall surface of the wastewater treatment pit 21, so as to measure the distance between the third reference portion P3 and the fourth reference portion P4; and a data recording part 7 for recording data measured by the first distance measurement part 2 and the second distance measurement part 3.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
