Drain pipes 5 are arranged in the drainage ditches 4. One end of the drain pipe 5 far away from the drainage ditch 4 is connected to the input end of the drainage pump 15.

[0029] In the embodiment of the utility model, the sludge can be loaded into the interior of the geotextile tube bag 1 through the input end 2 at the end of the geotextile tube bag 1. By loading the sludge into the plurality of geotextile tube bags 1, the packaging of the sludge can be realized. Then, through the laying of the tube bags in the storage tank and the filling of the filling area 13 between the two geotextile tube bags 1, the dewatering and consolidation of the sludge can be realized.

[0030] As Figures 1 to 5 shown, the height of the storage tank is higher than the total height of the plurality of stacked geotextile tube bags 1. When the dewatering device dewaters, the plurality of geotextile tube bags 1 can be stacked on the anti-seepage pad 3 or arranged in an array on the anti-seepage pad 3, which can be used for the extrusion dewatering of the upper geotextile tube bag 1 on the bottom geotextile tube bag 1. Then, through the setting that the storage tank is higher than the height of the plurality of stacked geotextile tube bags 1, the discharge and collection of the sewage in the geotextile tube bag 1 are facilitated.

[0031] The partition board 6 includes a support seat 10 fixed on the storage tank, a hole plate 8 fixed on the support seat 10, and a filter screen 9 covering the outside of the hole plate 8. The setting of the partition board 6 is used for the filter treatment outside the anti-seepage pad 3, which can improve the drainage rate of the sewage in the anti-seepage pad 3.

Through the filling of the filling area 13 between adjacent geotextile tube bags 1, it is convenient for the individual geotextile tube bags to be leveled and dewatered. The discharged water flows through the anti-seepage pad 3 and then flows to the drainage ditch 4. And through the protection treatment of the hole plate 8 at both ends of the anti-seepage pad 3, the water source can flow through the hole plate 8 and the filter screen 9 into a plurality of drainage branch pipes 7. Through the arrangement of the main pipe 16 at the bottom of the drainage branch pipes 7, it can be guided to the drainage ditch 4 to achieve the same collection of water sources. Then, by applying the water pumping technology of existing water pumps, the drainage pump 15 can pump the water source in the drainage ditch 4 to the top of the inclined slope 14 through the drain pipe 5 to achieve the transfer of the water source, reduce the water source in the storage tank, complete the dewatering and consolidation of the geotextile tube bags 1, and improve the dewatering efficiency of the geotextile tube bags 1.
