Hydraulic disk saw and underground diaphragm wall dismantling method

The invention provides a hydraulic disk saw and an underground diaphragm wall dismantling method. The underground diaphragm wall is dismantled through three processes of static cutting through the hydraulic disk saw, breaking through a hydraulic breaking hammer and chiseling away through a manual air pick. Cutting is started after construction of the adjacent structure bottom plates is completed, and the continuous wall above the top faces of the bottom plates is cut through a disk saw and demolished through a hydraulic breaking hammer; the top and the two sides of the single continuous wall are cut through the static cutting technology, reinforced concrete of the single continuous wall is disconnected, and it is guaranteed that vibration generated by the hydraulic breaking hammer cannot affect the surrounding structure to cause damage. 本发明提供了一种液压圆盘锯及地下连续墙拆除方法，地下连续墙拆除采用液压圆盘锯进行静力切割，液压破碎锤破碎、人工风镐凿除三种工艺进行施工；在相邻结构底板施工完成后开始切割，其中底板顶面以上连续墙采用圆盘锯进行切割、液压破碎锤拆除的方法；通过静力切割的工艺对单幅连续墙顶部、两侧进行切割，使单幅墙体的钢筋混凝土断开连接，保证液压破碎锤所产生的震动，不会波
