[0025] The present application will be further described below in combination with the drawings and specific embodiments.

[0026] As Figures 1-5As shown, the mud and sludge separation device for cast-in-place pile construction on steel platform of the present application comprises a box 2, which is surrounded 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 2 with an open top, a lifting ring 3 is arranged on the four corners of the top of the box 2, and a jacking device 1 is arranged on the four corners of the bottom of the box 2, which can be a hydraulic jack or a motor-driven jacking device. A sewage pipe and a sewage valve 6 are arranged on the box 2 near one of the jacking devices 1, the sewage pipe communicates with the inside of the box, and the sewage valve 6 is used to control the opening and closing of the sewage pipe for discharging the remaining mud after construction.

[0027] In one embodiment, the box 2 is composed of two 2m×1.5m×10mm steel plates, two 1m×1.5m×10mm steel plates and one 2m×1m×10mm steel plate, which consumes a total of 0.86t of steel.

[0028] The inside of the box 2 is provided with at least two circulating net boxes 4, 5, as shown. Figure 2 As shown, taking one of the circulating net boxes 4 as an example, the circulating net box 4 comprises three layers of net boxes, each of which comprises a net box body surrounded by a front side net, a rear side net, a left net, a right side net and a bottom net composed of wire mesh, and a vertical steel pipe is arranged at each of the four corners of the net box body, and the adjacent wire mesh of the net box body is fixed to the steel pipe. The bottom of the vertical steel pipe of the first and second layers of net boxes is configured as a reduced pipe, and the upper part of the vertical steel pipe of the second and third layers of net boxes is a hollow pipe, so that the bottom of the vertical steel pipe of the first layer of net boxes can be inserted into the upper part of the vertical steel pipe of the second layer of net boxes, and the bottom of the vertical steel pipe of the second layer of net boxes can be inserted into the upper part of the vertical steel pipe of the third layer of net boxes, so that when inserted, the corresponding side nets of the first, second and third layers of net boxes can be roughly joined.

[0029] In one embodiment, the upper part of the vertical steel pipe of the second and third layers of net boxes is provided with a limiting ring inside, so that when the vertical steel pipe of the previous layer of net boxes is inserted, it can be limited. The upper part of the vertical steel pipe of the first layer of net boxes remains sealed to prevent mud from entering.

[0030] A lifting ring 3 is arranged on the vertical steel pipe of each layer of net box bodies, so that the net box can be lifted.

[0031] Figure 3 As shown, a vertical transverse steel pipe 11 is arranged between the adjacent vertical steel pipes of each layer of net box bodies, and the transverse steel pipe 11 near the box side of the mud and sludge separation device needs to be holed in the middle of the steel pipe and welded with a reserved nut 12 on the inner side.

[0032] At the same time, the box 2 at the corresponding position is also provided with a hole 8, which corresponds to the hole position on the transverse steel pipe 11, and the counter pull screw 21 can be inserted between the two holes. In use, the counter pull screw 21 is only inserted from the outside of the box, and the counter pull screw 21 is tightened by rotating it, and the nut is tightened outside the box, so as to enhance the structure of the net cage to resist the impact of the slurry.

[0033] The edge length of the mesh hole of the bottom net of the first layer net cage is greater than the edge length of the mesh hole of the bottom net of the second layer net cage; the edge length of the mesh hole of the bottom net of the second layer net cage is greater than the edge length of the mesh hole of the bottom net of the third layer net cage. In this way, when the slurry falls from the first layer net cage, the large-diameter slag is first filtered and retained in the first layer net cage, the second-diameter slag is filtered and retained in the second layer net cage, and the smallest-diameter slag is filtered and retained in the third layer net cage.

[0034] 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.

[0035] In one embodiment, the front side net, the rear side net, the left net and the right side net are all wire meshes with a size of 1.8 m x 0.4 m (horizontal and vertical spacing of 5 mm, i.e. the edge length of the mesh hole is 5 mm). The upper part of the vertical steel pipe has a diameter of 40 mm (outer wall of 48 mm, inner wall of 3 mm) and a length of 0.4 m, and the lower part has a length of 50 mm and a diameter of 30 mm.

[0036] In one embodiment, from top to bottom, a piece of wire mesh with a size of 1.8 m x 1.8 m (horizontal and vertical spacing of 15 mm, i.e. the edge length of the square hole is 15 mm) is arranged at the bottom of the first layer, a piece of wire mesh with a size of 1.8 m x 1.8 m (horizontal and vertical spacing of 10 mm, i.e. the edge length of the square hole is 10 mm) is arranged at the bottom of the second layer, and a piece of wire mesh with a size of 1.8 m x 1.8 m (horizontal and vertical spacing of 5 mm, i.e. the edge length of the square hole is 5 mm) is arranged at the bottom of the third layer, forming a complete slurry circulating net cage.

[0037] 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 net cage 43 and welded to the box as the legs 431 of the circulating net cage 4.

[0038] As Figure 4As shown, in one embodiment, the legs 431 of the circulating net box 4 are embedded in the grooves 14 of the box bottom, and the inside of the grooves 14 is provided with a weighing sensor device 13. In this way, the grooves 14 not only serve to fix the circulating net box 4, but also can use the weighing sensor device 13 therein to monitor the mass of the circulating net box 4. When the mass of the circulating net box is greater than or equal to a predetermined value (the specific value is determined by the size of the circulating net box), it indicates that the sludge in the circulating net box has reached the limit value. At this time, the weighing sensor device 13 will alarm, for example, by means of a buzzer, or by means of communication to send an alarm to the mobile device, reminding the construction personnel to replace the circulating net box and hoist the circulating net box for cleaning. The weighing sensor device 13 is electrically connected and fixed on the controller outside the bottom of the box 2. The controller provides power to the weighing sensor device 13, receives the signal of the weighing sensor device 13, and transmits the signal to the mobile device.

[0039] In another embodiment, referring to Figure 5 , the weighing sensor device 13 is installed to the bottom of the leg 431 of the circulating net box 4. At this time, the weighing sensor device 13 is packaged with the microcontroller inside the bottom of the leg 431.

[0040] When drilling and pouring pile construction on a steel platform is carried out, this device can provide mud circulation for surrounding pile foundation construction. Two circulating net boxes can be used normally at the same time. If one circulating area needs to be cleaned, the other circulating area is also sufficient for use. Three layers of filter screens in one circulating area can also be used for circulating cleaning, greatly improving the mud circulation efficiency and ensuring the construction progress.

[0041] The use process is that the whole mud box is hoisted to the designated position by the automobile crane, whether it is level is observed by watching the bubble of the level gauge, then the four-corner jacking device 1 is used for adjustment and level keeping, and then pile foundation construction is carried out. The mud in the box is transported into the pile, and the corresponding particle size of the sludge is filtered out through the three layers of filter screens with different spacings. The filtered mud is transported to the pouring pile through the mud pump delivery pipe 7 at the bottom of the box. When the filter screen sludge needs to be cleaned, the outer nut of the box is unscrewed, the screw rod is rotated to be unscrewed, and then it can be directly hoisted out by the automobile crane, or when the groove fixing method is used, the weighing sensor device 13 will alarm, and the circulating net box is directly hoisted out. It does not affect the normal use of other circulating areas and other filter screens, and is sequentially circulated. After use, the three corners of the box are jacked up, and the valve of the other corner is opened to discharge the remaining mud in the box. A ladder 9 is also provided and erected on the box.

[0042] Through the double three-layer circulation system built in the box, the mud pool slag removal time is reduced, the mud circulation speed is accelerated, the construction efficiency is improved, the problem that the small operation space on the steel platform cannot place a large number of mud pools is solved, the unique jacking support system and the level are used to ensure that the box is horizontally placed and used on the steel platform, and the box mud discharge system formed by the pollution valve is used to greatly reduce the labor cost in the use process of the mud pool.

[0043] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
