Dredging method for bearing platform cofferdam
The invention discloses a desilting method for a bearing platform cofferdam, which comprises a first long-arm excavator and a second long-arm excavator, and an excavator bucket of the first long-arm excavator is replaced by a pull-out water spray gun. An excavator bucket of the second long-arm excavator is replaced by a hydraulic dredge pump, a hydraulic system of the second long-arm excavator is connected with a distribution valve, the distribution valve is in driving connection with the hydraulic dredge pump through a hydraulic oil pipe, and the hydraulic dredge pump is connected with a conveying pipe. The method further comprises the following steps that a first long-arm excavator drives a pulling type water spraying gun to stretch into the position below the liquid level of the cofferdam, and a first bucket hydraulic cylinder drives the pulling type water spraying gun to absorb water and spray water on site till sludge of the cofferdam falls to the bottom of the cofferdam from the side wall of the cofferdam. And the second long-arm excavator drives the hydraulic dredge pump to extend into the bottom of the cofferdam, and then a hydraulic system of the second long-arm excavator drives the hydraulic dredge pump to operate through the distribution valve, so that sludge is conveyed to the outside of the cofferdam along the conveying pipe. The working efficiency is high, and potential safety hazards to divers are eliminated.
本发明公开了用于承台围堰的清淤方法，包括第一长臂挖机和第二长臂挖机，第一长臂挖机的挖斗被替换为抽拉式喷水枪。第二长臂挖机的挖斗被替换为液压吸泥泵，第二长臂挖机的液压系统连接有分配阀，分配阀通过液压油管与液压吸泥泵驱动连接，液压吸泥泵连接有输送管。还包括如下步骤：通过第一长臂挖机驱动抽拉式喷水枪伸入围堰的液面下方，通过第一挖斗液压缸驱使抽拉式喷水枪进行就地吸水和喷水，直至将围堰的淤泥从围堰的侧壁掉落至围堰的底部。第二长臂挖机驱动液压吸泥泵伸入围堰的底部，然后第二长臂挖机的液压系统驱动通过分配阀驱使液压吸泥泵作业，以将淤泥沿输送管输送至围堰的外部。其不仅工作效率高，且消除了对潜水员的安全隐患。
