Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a breaking and removal construction method or the like for the face of a slope of mortar, which can conduct works mechanically and has high safety and in which the term of works can be shortened largely. SOLUTION: In the construction method, in which the face of the slope F covered with mortar such as the cut-open or the like of a road is cut and removed, a mortar section is cut successively in size capable of being carried out from the face of the slope F by high-pressure water injected from a high- pressure water injection nozzle and cut mortar is removed by using a service car A with the high-pressure water injection nozzle 3A arranged at the front end of a work arm 1A for the service car A disposed in an extensible manner and a cutter 2 supplying the nozzle with high-pressure water.
