The environment-friendly rapid dewatering device for the dredging sludge in the lakes and rivers can be designed according to the amount of the dredging sludge, and has the advantages of convenience in construction, good drainage effect, low manufacturing cost and the like.
In the embodiment, the vertical water filtering mechanism 3 is formed by combining a plurality of groups of vertical water filtering units; the plurality of groups of vertical water filtering units are arranged at intervals along the horizontal direction of the soil pit 100. The vertical water filtering mechanism 3 is formed by combining a plurality of groups of vertical water filtering units, the vertical water filtering units are arranged at equal intervals, the vertical water filtering units can be understood as 2 adjacent vertical water filtering units, and a sludge storage dehydration layer 1, a blocking layer 2 and a drainage layer 4 between the vertical water filtering units are combined into a dredged sludge rapid dehydration unit. When the lower part dredged sludge is dewatered, the volume is collapsed, the lower part dredged sludge can be compacted and continuously discharged into the dredged sludge upwards for dewatering. The solid sludge after the dehydration of the dredged sludge can be treated on site by means of greening closure, sanitary filling and the like. Generally, the larger the number of groups of vertical water filtering units, i.e. the larger the contact area of the dredging sludge per unit area with the vertical water filtering units, the faster the dewatering speed per unit time.
In this embodiment, the horizontal height of the upper end of the vertical water filtering unit is higher than the horizontal height of the upper surface of the sludge storage and dewatering layer 1. The horizontal height of the upper end of the vertical water filtering unit is higher than the horizontal height of the upper surface of the sludge storage dewatering layer 1, so that dredged sludge with different depths can be dewatered together, the dredged sludge is dewatered uniformly, and the upper end of the vertical water filtering unit is higher than the upper end of the vertical water filtering unit for air intake, so that water can flow and be discharged quickly. The level of the upper surface of the sludge storing and dewatering layer 1 is lower than the ground level of the excavated soil pit 100, i.e. the ground above the dredged sludge has a certain distance, and the vertical height of the vertical water filtering unit can be designed according to the amount of the dredged sludge treated every day, so that the dredged sludge is prevented from filling the sludge storing and dewatering layer 1 and overflowing from the soil pit 100, and the operation is increased.
Preferably, the vertical water filtering unit adopts one of a water collecting well, a pipe well, a vertical plastic drainage pipe, a sand pile, a bagged sand well and a sand stone pile which penetrate through the sludge storage dewatering layer 1 and the blocking layer 2 and reach the drainage layer 4.

The thickness of each treatment layer and the proportion of each layer in the soil pit 100 are reasonably designed to realize the maximum treatment of the dredged sludge in the soil pit 100.
In this embodiment, the thickness of the barrier layer 2 is larger than that of the drainage layer 4. The drainage layer 4 is mainly a temporary reservoir, is a cavity when no water exists, and is prevented from collapsing due to the fact that the drainage layer 4 is too thick and cannot bear the mud storage dewatering layer 1 and the blocking layer 2, therefore, the thickness of the drainage layer 4 is smaller than that of the blocking layer 2, and on the premise that the structural stability is met, the thickness of the mud storage dewatering layer 1 is guaranteed to be the largest as possible, so that the amount of the treated dredging mud is the largest.
In this embodiment, the barrier layer 2 is made of one of a compacted soil layer, a waterproof concrete layer, and a reinforced concrete layer. The barrier layer 2 is used for blocking the passage of dredged sludge, i.e., solid sludge and water, to trap the solid sludge at the bottom of the sludge storage dehydration layer 1.
In this embodiment, the sidewall and/or the bottom of the pit 100 is provided with a waterproof layer for preventing leakage. The waterproof layer has a waterproof effect on the side wall and the bottom of the soil pit 100, so that water leakage is prevented, and the surrounding environment is prevented from being polluted. The waterproof layer also has certain capacity of resisting external damage. Preferably, the waterproof layer adopts at least one of waterproof glue layer, cement layer, pitch layer or waterproof coating layer.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
