摘要

PURPOSE: To increase cleaning efficiency by disposing a brush for cleaning outer periphery of a sheet pile, and also a knife inserted into a sheet pile joint portion and a pawl for rotating from joint to a joint groove portion and so inserting into a joint groove. ;CONSTITUTION: A crawler device 40 placed over a sheet pile A is raised and a frame 1 is lowered, and upper face brush and side face brush 30 are brought into contact with upper face and side face of the pile A. Then, both brushes are rotated and simultaneously the device 40 is further raised, by coordinating cam plate, guide bar, etc., a knife and a pawl in a removal device 50 are swung downward and inserted into a joint of the pile A. When the device 40 moves into a second stage rise, the pawl of the device 40 rotates outward via fitting of an arch-formed guide bar and a cam plate and so goes into a joint groove of the pie A. The machine is moved forward with a driving device 10, so that outer surface of the pile A is cleaned and sediment in the groove is removed. Accordingly, sediment is removed completely, and occurrence of sand dust, noise, etc., is prevented.;COPYRIGHT: (C)1996,JPO
