[0020] The present utility model will be further described below in conjunction with the accompanying drawings and detailed implementation manners.

[0021] As Figures 1-5 shown, a sludge separation device of the present utility model includes a box body 2. The box body 2 is enclosed by a front side plate, a rear side plate, a left side plate, a right side plate and a bottom plate to form a sealed box body 2 with an open upper part. Hoisting rings 3 are arranged at the four corners above the box body 2, and jacking devices 1 are respectively arranged at the four corners below the box body 2. The jacking device 1 can be, for example, a hydraulic jack or a jacking device driven by a motor. A sewage discharge pipe and a sewage discharge valve 6 are arranged on the box body 2 near one of the jacking devices 1. The sewage discharge pipe communicates with the inside of the box body, and the sewage discharge valve 6 is used to control the opening and closing of the sewage discharge pipe for discharging the remaining slurry after construction.

[0022] In one embodiment, the box body 2 is composed of 2 steel plates of 2m×1.5m×10mm, 2 steel plates of 1m×1.5m×10mm, and 1 steel plate of 2m×1m×10mm, consuming a total of 0.86t of steel.

[0023] At least two circulation cages 4, 5 are arranged inside the box body 2. As Figure 2 shown, taking one of the circulation cages 4 as an example, the circulation cage 4 includes three layers of cages. Each layer of cage includes a cage body surrounded by a front side net, a rear side net, a left net, a right side net and a bottom net made of wire mesh. A vertical steel pipe is arranged at each of the four corners of the cage body, and the adjacent wire meshes of the cage body are fixed to the steel pipe. The bottom of the vertical steel pipes of the first and second layers of cages is configured as a reduced-diameter pipe, and the upper part of the vertical steel pipes of the second and third layers of cages is a hollow pipe. In this way, the bottom of the vertical steel pipe of the first layer of cage can be inserted into the upper part of the vertical steel pipe of the second layer of cage, and the bottom of the vertical steel pipe of the second layer of cage can be inserted into the upper part of the vertical steel pipe of the third layer of cage, so that when inserted, the corresponding side nets of the first, second and third layers of cages can be approximately joined.

[0024] In one embodiment, a limiting ring is arranged inside the upper part of the vertical steel pipes of the second and third cages, so that when the vertical steel pipe of the upper layer of cage is inserted, it can be limited. The upper part of the vertical steel pipe of the first layer of cage is kept in a sealed state to prevent slurry from entering.

[0025] Hoisting rings 3 are arranged on the vertical steel pipes of each layer of cage body, so that the cage can be lifted.

[0026] Figure 3As shown, vertical transverse steel pipes 11 are arranged between adjacent vertical steel pipes of each layer of the mesh box body. The transverse steel pipes 11 on the side of the box body close to the sludge separation device need to be drilled in the middle of the steel pipe and reserved nuts 12 are welded on the inner side thereof.

[0027] At the same time, the box body 2 is also drilled at the corresponding position. The hole 8 corresponds to the drilled position on the transverse steel pipe 11. A tie rod 21 can be inserted between the two holes. During use, only the tie rod 21 needs to be inserted from outside the box body, the tie rod 21 is rotated to be tightened, and the nut is tightened outside the box body, so that the anti-mud impact ability of the mesh box body structure can be enhanced.

[0028] The side length of the mesh holes of the bottom net of the first-layer mesh box is greater than the side length of the mesh holes of the bottom net of the second-layer mesh box; the side length of the mesh holes of the bottom net of the second-layer mesh box is greater than the side length of the mesh holes of the bottom net of the third-layer mesh box. In this way, when the mud falls from the first-layer mesh box, the slag with a large diameter is first filtered and left in the first-layer mesh box, the slag with the second-largest diameter is filtered and left in the second-layer mesh box, and the slag with the smallest diameter is filtered and left in the third-layer mesh box.

[0029] In one embodiment, each transverse steel pipe 11 is a steel pipe with a diameter of 40 mm and a length of 1.8 m.

[0030] In one embodiment, the front net, rear net, left net and right net are all wire meshes of 1.8 m × 0.4 m (the horizontal and vertical spacing is 5 mm, that is, the side length of the mesh hole is 5 mm). The upper part of the vertical steel pipe has a diameter of 40 mm (outer wall 48 mm, inner wall 3 mm), a length of 0.4 m, and the length of the diameter-reduced part at the lower part is 50 mm, and the diameter is 30 mm steel pipe.

[0031] In one embodiment, from top to bottom, a wire mesh of 1.8 m × 1.8 m (horizontal and vertical spacing 15 mm, that is, a square with a side length of 15 mm) is arranged at the bottom of the first layer, a wire mesh of 1.8 m × 1.8 m (horizontal and vertical spacing 10 mm, that is, a square with a side length of 10 mm) is arranged at the bottom of the second layer, and a wire mesh of 1.8 m × 1.8 m (horizontal and vertical spacing 5 mm, that is, a square with a side length of 5 mm) is arranged at the bottom of the third layer, forming a complete mud circulation mesh box.

[0032] Four vertical steel pipes with a diameter of 40 mm and a length of 0.3 m are arranged at the bottom of the third-layer mesh box 43 and welded to the box body as the legs 431 of the circulation mesh box 4.

[0033] As Figure 4As shown, in one embodiment, the legs 431 of the circulating cage 4 are embedded in the grooves 14 at the bottom of the box body. A weighing sensor device 13 is arranged inside the grooves 14. In this way, the grooves 14 not only play a role in fixing the circulating cage 4, but also can use the weighing sensor device 13 therein to monitor the mass of the circulating cage 4. When the mass of the circulating cage is greater than or equal to a certain value (the specific value is determined by the size of the circulating cage), it indicates that the sludge in the circulating cage has reached the limit value. At this time, the weighing sensor device 13 will give an alarm, for example, by beeping, or by sending an alarm to a mobile device through communication, to remind the construction personnel to replace the circulating cage and lift the circulating cage for cleaning. The weighing sensor device 13 is electrically connected to a controller fixed at the bottom outside of the box body. The controller provides electrical energy to the weighing sensor device 13, receives the signal of the weighing sensor device 13, and transmits the signal to the mobile device.

[0034] In another embodiment, refer to Figure 5 , the weighing sensor device 13 is installed at the bottom of the legs 431 of the circulating cage 4. At this time, the weighing sensor device 13 and the microcontroller are encapsulated together inside the bottom of the legs 431.

[0035] When bored cast-in-place piles are constructed on a steel platform, this device can be used for the mud circulation of the surrounding pile foundations. Two circulating cages can be used normally at the same time. If slag cleaning is required in one circulating area, the other circulating area is sufficient to supply and use. And three layers of filter meshes in one circulating area can also carry out circulating slag cleaning, greatly improving the mud circulation efficiency and ensuring the construction progress.

[0036] The using process is as follows: The whole mud box is lifted to the designated position by a truck crane. Check whether it is level by observing the bubble of the spirit level, and then use the jacking devices 1 at the four corners to adjust and keep it level. Then carry out pile foundation construction. The mud replaced from the pile is transported into the mud box. The corresponding particle size of sludge is filtered out through three layers of filter meshes with different spacings. The filtered mud is transported to the bored cast-in-place pile through the mud pump delivery pipe 7 at the bottom of the box body. When the filter mesh has too much sludge and needs to be cleaned, first unscrew the external nut outside the box, then rotate the screw rod to unscrew it, and then directly lift it out with a truck crane. Or, when the groove fixing method is adopted, when the weighing sensor device 13 gives an alarm, directly lift out the circulating cage. It does not affect the normal use of other circulating areas and other filter meshes, and circulates in turn. After use, jack up the three corners of the box body and open the valve at the other corner to discharge the remaining mud in the box. A ladder 7 is also provided and built on the box body.

[0037] Through the dual three-layer circulation system built in the box, the time occupied by slag cleaning in the mud pit is reduced, the mud circulation speed is accelerated, and the construction efficiency is improved. At the same time, the problem that a large number of mud pits cannot be placed due to the small working space on the steel platform is solved. Moreover, through the unique jacking support system and spirit level, the box can be placed horizontally and used on the steel platform, and the in-box mud discharge system composed of sewage discharge valves greatly reduces the labor cost in the process of using the mud pit.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
