Preparation for grouting operation: Connect the diesel generator to each power facility on the platform to supply power through the diesel generator; according to the ambient temperature and the requirements of the grouting operation, turn on the temperature control regulator of the fresh water storage tank to preheat the clean water in the tank; set the initial speed of the agitator of the grouting mixing tank to the lowest gear, and close the flow regulating valve on the end side of the high-pressure delivery hose; determine the design parameters of the grouting operation, including the grouting material ratio, stirring speed, grouting flow rate and target pressure; S3, grouting operation: start the agitator of the grouting mixing tank, operate the crane to lift the bagged grouting base material and put it into the bag breaking device above the grouting mixing tank; Turn on the water pump to pump clean water with a certain temperature into the grouting mixing tank at a preset flow rate, and mix it with the grouting base material to form grouting material until the preset ratio requirement and amount are reached; turn on the grouting delivery pump, and adjust the opening of the flow regulating valve on the end side of the high-pressure delivery hose, so that the grouting material is pumped into the delivery pipeline of the conductor rack below at a preset flow rate for subsequent grouting operations; S4. Processing after the operation is completed: After the grouting operation is completed, shut down the power facilities in the grouting operation in turn according to the equipment operation specifications; then remove the hydraulic locking device between the working platform and the conductor frame, and use the same method to lift and transport the working platform back to the dock; clean and maintain the grouting operation facilities of the working platform at the dock, and wait for the next operation.
