The invention relates to the technical field of cofferdam construction, in particular to a special steel sheet pile dismantling device for cofferdam construction, which comprises a dismantling frame and an L-shaped moving table, two rail sliding grooves, two penetrating grooves and two limiting grooves are formed in the dismantling frame, and four supporting short blocks I are fixedly connected to the inner wall of the dismantling frame. According to the steel sheet pile pushing device, by arranging an upward pushing clamping block, an annular pushing block, a transmission pushing rod, a rubber piston and other components, through the mutual matching relation between the annular pushing block component and the upward pushing clamping block as well as between the annular pushing block component and the transmission pushing rod component, the upward pushing clamping block component can clamp and push up a steel sheet pile through upward movement; and therefore, the effect that sprayed water flow can be controlled through a rubber piston on a transmission push rod is achieved, the outer surface of the steel sheet pile is subjected to high-pressure washing while the steel sheet pile is pulled out, soil attached to the outer surface of the steel sheet pile falls off, rusting is prevented, and the service life of the steel sheet pile is prolonged.

本申请涉及围堰施工的技术领域，尤其是涉及一种围堰施工专用钢板桩拆除装置，其包括拆除框和L型移动台，所述拆除框的内部开设有两个轨道滑槽、两个贯穿槽和两个限位槽，所述拆除框的内壁固定连接有四个支撑短块一。本申请能够通过设置上推夹持块、环形推块、传动推杆、橡胶活塞等部件，通过环形推块部件与上推夹持块和传动推杆部件之间相互的配合关系，使得上推夹持块部件能够通过上移对钢板桩进行夹持上推，进而达到了本装置能够通过传动推杆上的橡胶活塞对喷出的水流进行控制的效果，达到了在拔除钢板桩的同时，对钢板桩外表面进行高压冲洗，使钢板桩外表面粘附的泥土脱落，防止生锈，提高钢板桩的使用寿命。
