Abstract
PURPOSE:To correct the inclination of a rotary vertical shaft by keeping the interval of the rotary vertical shaft by a method in which the lower ends of rotary vertical shafts are rotatably connected with each other, and pit wall pressing mean are provided vertically and mutually, pushing in different directions. CONSTITUTION:In a multispindle excavator 1, a number of rotary vertical shafts 2 are set in parallel and their lower parts are rotatably connected by a connector 3 having at least two pit wall pressing means 5 vertically, whose pushing directions are different. The presser 5, consisting of an oil-pressure jack and a rotary roller or a sleigh pivotally supported on the tip of the jack, serves to correct the inclination of the shaft 2 by the back and forth moving of the oil-pressure jack. The attitude of the rotary vertical shaft can thus be simply corrected.
