Obstacle cleaning method in cofferdam sinking
A method for cleaning obstacles in cofferdam sinking belongs to the technical field of cofferdam construction, can solve the problems that obstacles exist in the sinking process of a steel cofferdam blade angle in a river channel, the construction space between a steel cofferdam and a pile casing is limited and the like, and comprises a breaking hammer used for breaking the obstacles and a positioning control device used for controlling the perpendicularity of the breaking hammer. The breaking hammer comprises a hammer rod and a hammer head located at one end of the hammer rod, the front end of the hammer head is of a prismatic structure, the positioning control device comprises an upper rectangular frame and a lower rectangular frame, the rectangular frames are connected through connecting rods, jacks are arranged in the centers of the four edges of each rectangular frame respectively, and steel plates are arranged at the piston rod ends of the jacks. Fixed pulleys are arranged at the front ends of the steel plates. By the adoption of the self-machining hammer, obstacle cleaning can be completed in a water surface limited space, the self-machining hammer is hoisted through the crawler crane, and the obstacle is crushed and fished through the self-weight of the self-machining hammer. Manpower and material resources are effectively saved, equipment investment is low, and the processing speed is high.
一种围堰下沉中障碍物清理清理方法，属于围堰施工技术领域，可解决钢围堰刃角再河道内下沉过程中存在障碍物，在钢围堰与护筒之间施工空间有限等问题，包括用于破碎障碍物的破碎锤和用于控制破碎锤垂直度的定位控制装置，所述破碎锤包括锤杆和位于锤杆一端的锤头，所述锤头的前端为棱型结构，所述定位控制装置包括上下两层矩形框架，所述矩形框架通过连接杆连接，矩形框架的四边中心位置分别设有千斤顶，千斤顶的活塞杆端设有钢板，钢板前端设有定滑轮。通过使用本发明，能够在水面受限空间内完成障碍物清理，通过利用履带吊起吊自加工锤头，利用自重对障碍物破碎，进行打捞。有效节省人力物力，设备投入少，处理速度快。
