Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment in water conservancy projects, in particular to a sludge treatment device for water conservancy projects. Background Art

[0002] River siltation will affect the normal performance of various functions such as flood control, drainage, irrigation, water supply, and navigation. In order to restore the normal functions of the river, regular river dredging is required.

[0003] Geotube dewatering is a commonly used method for sludge reduction. In engineering, the sludge removed from the dredging is mixed with flocculants and introduced into geotubes. The water in the sludge is removed from the tubes by the weight of the sludge or by applying a load above the tubes, while the sludge remains inside the tubes, thereby achieving sludge reduction.

[0004] Geotube dehydration utilizes two dynamic factors: the filtration structure of the equivalent aperture formed by the weaving of the geotube material and the liquid pressure in the bag to achieve mud and water separation. However, when the existing geotube is in use, after the silt fills and expands the geotube, the bottom of the geotube fits with the ground (or the upper surface of another geotube piled below), which reduces the permeable area of ​​the geotube and affects the mud-water separation efficiency. Based on this, in order to further improve the mud-water separation efficiency, a silt treatment device for water conservancy projects is provided. Utility Model Content

[0005] The purpose of the present utility model is to provide a sludge treatment device for water conservancy projects in order to solve the problems in the above background.

[0007] As a further solution of the present invention: a separator cloth is sewn and fixed on the inner side of the geotube bag, and the geotube bag is formed with a concave guide groove by the separator cloth, and the concave guide groove is symmetrically distributed on the upper and lower surfaces of the geotube bag.

[0008] As a further solution of the present invention: a plurality of the partitioning cloths are provided and evenly distributed in the horizontal direction, and the internal cavity of the geotube bag is divided into a plurality of independent spaces by the plurality of partitioning cloths;

[0009] A through hole is provided at a position near the top of the separating cloth, and a plurality of through holes are evenly arranged along the horizontal and longitudinal directions.

[0011] As a further solution of the present invention: the pads are distributed on both sides of the concave guide groove at the bottom of the geotube bag, and the longitudinal length of the pads is greater than the distance between two adjacent drainage guide strips in the longitudinal direction.

[0012] As a further solution of the present invention: the width and length of the waterproof pad are respectively greater than the width and length of the geotube bag.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] By setting up separator cloths, multiple concave guide grooves are formed on the upper and lower surfaces of the geotube bag. At the same time, multiple separator cloths divide the inner cavity of the geotube bag into multiple independent spaces. Compared with the traditional integrated inner cavity structure of the geotube bag, the contact area between the silt and the geotube bag is further increased. At the same time, there is a gap between the bottom of the geotube bag and the waterproof pad cloth under the action of the pad, so that water can seep out through the lower surface of the geotube bag and flow along the gap, thereby increasing the permeable area, thereby achieving the purpose of improving the mud-water separation efficiency.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 3 In an embodiment of the utility model, a silt treatment device for a water conservancy project includes a geotube bag 1 and a flushing cuff 2 sewn and fixed to one side of the geotube bag 1. A pad 3 is bonded and fixed to the bottom of the geotube bag 1. A plurality of pads 3 are provided, and the plurality of pads 3 are evenly distributed in a matrix. A waterproof pad 4 is bonded and fixed to the bottom of the plurality of pads 3. After the geotube bag 1 is filled with silt and expanded, a gap is formed between the lower surface of the geotube bag 1 and the upper surface of the waterproof pad 4 through the pad 3, which is used to provide a flow channel for water seeping out of the bottom of the geotube bag 1.

[0021] A separator cloth 5 is sewn and fixed on the inner side of the geotube bag 1. The geotube bag 1 is formed with a concave guide groove 7 by the separator cloth 5. The concave guide grooves 7 are symmetrically distributed on the upper and lower surfaces of the geotube bag 1.

[0022] A plurality of separating cloths 5 are provided and evenly distributed along the horizontal direction, and the internal cavity of the geotube bag 1 is divided into a plurality of independent spaces by the plurality of separating cloths 5;

[0023] A through hole 6 is provided near the top of the separating cloth 5 , and a plurality of through holes 6 are evenly arranged along the horizontal and longitudinal directions.

[0024] In this embodiment, it should be noted that the irrigation cuff 2 is connected to the inner cavity of the geotube bag 1. When dehydrating the sludge, the sludge mixed with the flocculant is poured into the geotube bag 1 through the irrigation cuff 2 by an external conveying device, so that the geotube bag 1 expands. In this process, the filtration structure of the equivalent pore size formed by the weaving of the geotube bag 1 itself and the pressure of the liquid in the bag allow the water in the sludge to permeate out of the outside of the geotube bag 1, thereby achieving mud-water separation.

[0025] At the same time, as the geotube bag 1 expands, under the limiting action of the separating cloth 5, multiple concave guide grooves 7 are formed on the upper and lower surfaces of the geotube bag 1. At the same time, multiple separating cloths 5 divide the inner cavity of the geotube bag 1 into multiple independent spaces. Compared with the traditional geotube bag's integrated inner cavity structure, the contact area between the silt and the geotube bag 1 is further increased. At the same time, under the action of the pad 3, there is a gap between the bottom of the geotube bag 1 and the waterproof pad 4, so that water can seep out through the lower surface of the geotube bag 1 and flow away along the gap, thereby increasing the permeable area, thereby achieving the purpose of improving the mud-water separation efficiency.

[0026] Please refer to Figures 1 to 3 The upper surface of the geotube bag 1 is bonded with a drainage guide bar 8, which is distributed on both sides of the concave guide groove 7, and a plurality of drainage guide bars 8 are evenly arranged along the horizontal longitudinal direction;

[0027] The pads 3 are distributed on both sides of the concave guide groove 7 at the bottom of the geotube bag 1. The longitudinal length of the pads 3 is greater than the distance between two adjacent drainage guide strips 8 in the longitudinal direction.

[0028] The width and length of the waterproof pad 4 are respectively greater than the width and length of the geotube bag 1 .

[0029] In this embodiment, the drainage strips 8 are arranged so that the water that permeates through the upper surface of the geotube bag 1 can flow along the track of the drainage strips 8 into the concave guide groove 7 and be discharged outward along the track of the concave guide groove 7, thereby further improving the water drainage efficiency.

[0030] If multiple geotextile tube bags 1 are stacked, a spacer 3 on the upper geotextile tube bag 1 can be fitted with multiple drainage strips 8 on the lower geotextile tube bag 1, thereby ensuring that the gap between the upper geotextile tube bag 1 and its corresponding waterproof pad 4 will not be blocked, and the middle area of ​​the drainage strips 8 on the lower geotextile tube bag 1 will not be blocked;

[0031] In addition, because the width and length of the waterproof pad 4 are respectively greater than the width and length of the geotextile tube bag 1, the upper waterproof pad 4 can cover the lower geotextile tube bag 1, and then the water seeping out of the upper geotextile tube bag 1 will not flow onto the lower geotextile tube bag 1, so that the multiple geotextile tube bags 1 are independent of each other and do not affect each other.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
