When the subway station is renovated and rebuilt, the support piles need to be removed, so a support pile cutting device is needed. The existing support pile cutting device mainly uses a chain saw, which needs to cut the top and bottom of the support pile separately. However, since the top of the support pile is at a high position, the construction workers need to perform high-altitude operations, and the chain saw needs to be hand-held, resulting in the reaction force of the chain saw during construction, which can easily push the construction workers and make them fall from heights. At the same time, the chain saw is prone to breakage during the cutting process, causing the broken chain to rebound and come into contact with the construction workers, causing injuries to the construction workers.
