[0031] Between the upper and lower adjacent pad structures 1, a retaining structure 3 is provided; Figure 6-7 The main body of the enclosure structure 3 is a geotextile 3-1; the bottom of the enclosure structure 3 is inserted into the limiting hole 1-2 of the adjacent pad structure 1 in the lower layer, and the bottom of the enclosure structure 3 is spaced apart with a second fixing unit 3-2 matching the first fixing unit 1-3, and the second fixing unit 3-2 is connected with the first fixing unit 1-3 by snapping.

[0032] As a preferred structure, see Figure 3The first fixing unit 1-3 includes a fabric through hole 1-3-1 and a perforated card slot 1-3-2; fabric through holes 1-3-1 are evenly arranged around the edge of the limiting hole 1-2, and two adjacent fabric through holes 1-3-1 are connected by the perforated card slot 1-3-2.

[0033] See also Figure 7 The second fixing unit 3-2 includes a fabric positioning bolt 3-2-1 and a positioning clamping column 3-2-2; the fabric positioning bolts 3-2-1 are arranged at intervals and fixed with the fabric through holes 1-3-1; a positioning clamping column 3-2-2 is arranged at both ends of each fabric positioning bolt 3-2-1, and the positioning clamping column 3-2-2 is clamped inside the perforated card slot 1-3-2.

[0034] The connection between the enclosure structure 3 and the pad structure 1 thereunder is achieved through the clamping connection between the first clamping unit 1 - 3 and the second clamping unit 3 - 2 .

[0035] Furthermore, in order to strengthen the connection between the pad structure 1 and the enclosure structure 3 and achieve a stable fixing effect on the enclosure structure 3, a second fixing unit 3-2 is also arranged at intervals on the top of the enclosure structure 3; the second fixing unit 3-2 on the top of the topmost enclosure structure 3 is used for fixing and connecting with the first fixing unit 1-3 of the pad structure 1 above it.

[0036] A specific embodiment is described below:

[0037] The bottom of the pad structure 1 is as follows Figure 2 As shown, the front and rear sides are uniformly provided with positioning holes 1-1 along the length direction, and the surrounding of the pad structure 1 is uniformly provided with fabric through holes 1-3-1. In order to reduce the difficulty of component manufacturing, a perforated card slot 1-3-2 is provided to realize the connection between the fabric through holes 1-3-1.

[0039] Enclosure structure 3 Figure 6 As shown, the main body is surrounded by geotextile 3-1, and fabric positioning bolts 3-2-1 are set at the top and bottom. The two ends of the fabric positioning bolts 3-2-1 are positioning posts 3-2-2 for easy positioning and mutual cooperation with the pad structure. The details are as follows Figure 7 shown.

[0040] The usage is:

[0041] Step 1: Install the first layer of pad structure 1:

[0042] Level the ground, lay the first-layer pad structure 1 flat on the ground, and then drive the positioning columns 2 through the positioning holes 1-1 of the first-layer pad structure 1 into the stratum; the number of positioning columns 2 mainly depends on the size of the sludge dewatering device and the mass and density of the loaded sludge; through this step, the installation and fixation of the first-layer pad structure 1 is achieved.

[0043] Step 2: Install the first layer of enclosure structure 3:

[0044] The fabric positioning bolt 3-2-1 at the bottom of the first-layer enclosure structure 3 is inserted into the fabric through hole 1-3-1 of the first-layer pad structure 1, and the positioning clamping column 3-2-2 is clamped in the perforated clamping slot 1-3-2, so as to realize the clamping between the first-layer enclosure structure 3 and the first-layer pad structure 1, thereby improving the overall structural stability;

[0045] Through this step, the first layer of the enclosure structure 3 and the first layer of the pad structure 1 are fixedly connected. At the same time, the first layer of the pad structure 1 is prevented from slipping and deforming by the limiting effect of the limiting holes 1-2 of the first layer of the pad structure 1 and the limiting effect of the surrounding positioning columns 2 on the first layer of the enclosure structure 3.

[0046] If large gaps appear in the fabric through-holes 1-3-1 after repeated use, geotextiles may be laid on them to reduce the amount of infiltration.

[0047] Step 3: Pour the plasticized sludge into the interior of the first-layer enclosure structure 3. During the pouring process, the force should be kept as uniform as possible to prevent tilting;

[0048] Step 4: Install the second layer of base plate structure 1:

[0049] After the first layer of enclosure structure 3 is filled with plasticized sludge, the second layer of pad structure 1 is slowly lowered to a stable height through the positioning columns 2 so that the second layer of pad structure 1 is in contact with the top surface of the first layer of enclosure structure 3 .

[0050] Step 5: Install the second layer of enclosure structure 3:

[0051] On the second-layer pad structure 1, the second-layer enclosure structure 3 is fixedly installed;

[0052] Step 6: Pour the plasticized sludge into the interior of the second-layer enclosure structure 3.

[0053] This cycle is repeated continuously to achieve the installation of multi-layer pad structures 1 and multi-layer enclosure structures 3. After reaching the set number of layers, the top-layer pad structure 1 is installed on the top of the top-layer enclosure structure 3, so that the top-layer pad structure 1 and the second fixing unit 3-2 on the top of the top-layer enclosure structure 3 are clamped together to achieve the stacking setting of the multi-layer enclosure structure.

[0054] The utility model provides a sludge dewatering device, which has the following advantages:

[0055] (1) It can realize multi-layer stacking simply and stably. After the lower bag body is basically stable, the upper bag body can be injected with mud. Due to the fixation of the positioning column and the cooperation of the clamping unit, the bag will not slip;

[0056] (2) By stacking multiple layers of geobags, the floor space can be reduced and investment can be saved.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be considered as the protection scope of the present invention.
