1. A movable water-permeable pile spur dike, comprising a fixed rail (2), a plurality of movable rails (3), a plurality of movable water-permeable piles (1), pressure sensors (11), flow meters (12) and a control platform (4),
wherein one end of each movable rail (3) is slidably connected to one side of a downstream face of said fixed rail (2), and is configured to move relatively in the extending direction of said fixed rail (2);
said plurality of movable water-permeable piles (1) are arranged on said fixed rail (2) and said plurality of movable rails (3);
said pressure sensors (11) and said flow meters (12) are arranged at each monitoring point on an outer side wall of each movable water-permeable pile (1) and respectively used to monitor the changes in the water pressure on each monitoring point and the changes in the water flow velocity about the monitoring point;
said plurality of movable rails (3), said plurality of movable water-permeable piles (1), each of said pressure sensors (11) and each of said flow meters (12) are respectively connected to said control platform (4) in a communication mode, which is used for analysis and calculation according to monitoring data from each of said pressure sensors (11) and each of said flow meters (12) and adjusts the positions of each movable rail (3) and each movable water-permeable pile (1), so that the water flow velocity and spur dike's pressure at each monitoring point are both less than a corresponding flow velocity threshold value and pressure threshold value, and the spur dike's water permeability falls within a setting range.
