[0002] At present, the mud discharged from drilling and piling in bridge projects is one of the sources of waste soil in road construction projects. The usual treatment method for these high-water content muds is to pile them up for sedimentation treatment on site or transport them to the suburbs by tank trucks and then evaporate them naturally.

Under the transmission of the third conveyor belt, the winding shafts on both sides are controlled to rotate, driving the winding wheels at both ends to rotate and tighten, thereby controlling the steel wire rope wound on the surface to be wound and tightened, driving the holding frame below to move upward, thereby controlling the solidified mud to be lifted to the top of the sedimentation tank for cleaning and transportation. During the cleaning and transportation operation, the cleaning door on one side of the holding frame is opened to quickly clean the solidified mud.

[0024] Step 5: After the solidified mud is cleaned, the rotating motor is controlled to reverse, and then the winding wheel is controlled to release the wire rope, and the frame moves downward and resets under its own weight, waiting for the next advance operation.

[0025] The beneficial effects of the present invention are:

[0037] Reference Figure 1-Figure 7 A mud solidification treatment device in pile foundation construction includes an equipment support leg 1 and a sedimentation tank 2. At least four equipment support legs 1 are provided. The tops of the four equipment support legs 1 are respectively provided with a first filtering and screening mechanism 3, a second filtering and screening mechanism 4 and a connecting drive mechanism 5.

[0038] In order to realize the gravel screening and filtering operation of the mud in the pile foundation construction, the first filtering and screening mechanism 3 includes a sedimentation barrel 31 and a drive mounting ring 32. The tops of the four equipment support legs 1 are fixedly installed with the bottom of the sedimentation barrel 31. The top of the sedimentation barrel 31 is threadedly connected to the bottom end of the drive mounting ring 32. The top of the drive mounting ring 32 is threadedly connected with a filter protective cover 33. The inner wall of the filter protective cover 33 is inclined. One side of the bottom end of the sedimentation barrel 31 is fixedly connected with a water outlet pipe 34. The surface of the water outlet pipe 34 is provided with a first valve 35. The bottom end of the water outlet pipe 34 is located above the sedimentation tank 2.

[0039] Specifically, the filter protection cover 33 is threadedly connected to the drive mounting ring below, which facilitates the cleaning of the gravel left after filtration, and the bottom end of the sedimentation barrel 31 is provided with an outlet pipe 34 and a first valve 35. When removing mud from the sedimentation tank 2, the first valve 35 can be closed to perform the removal operation, thereby avoiding the effect of the outlet pipe 34 affecting the drainage operation during the removal operation.

[0040] In order to control the mud inside the filter protective cover 33 to filter sand and gravel, a connecting rod 36 is fixedly installed on the inner wall of the drive mounting ring 32. The top of the connecting rod 36 is conical in shape. The middle part of the connecting rod 36 is rotatably connected to the rotating shaft 37 through a bearing. The arc surface of the rotating shaft 37 is fixedly installed with a first pulley 38. The top of the rotating shaft 37 is fixedly installed with a screening cover 39. The top surface of the screening cover 39 is conical in shape. The surface of the screening cover 39 is provided with a filtering hole 310. The upper surface of the bottom disc of the screening cover 39 contacts and rubs with the bottom of the filter protective cover 33. The axis of the screening cover 39 is eccentric to the axis of the rotating shaft 37. The rotation of the rotating shaft 37 controls the eccentric swing of the screening cover 39.

[0041] Specifically, the rotation of the rotating shaft 37 drives the screening cover 39 to rotate eccentrically, thereby controlling the mud to filter the sand and gravel using the filter under the eccentric rotation operation, and utilizing the eccentric rotation swing to avoid the effect of blockage caused by the retention of sand and gravel filtering.

[0042] In order to realize the fine sand screening and filtering operation of the mud in the pile foundation construction, the second filtering and screening mechanism 4 includes a sand storage frame 41 and a spiral filter tube 42. A sand discharge pipe 43 is fixedly installed at the bottom of the sand storage frame 41. The bottom end of the sand discharge pipe 43 is rotatably connected to the inner bottom wall of the sedimentation barrel 31 through a bearing. A discharge pipe 44 is fixedly installed inside the bottom end of the sand discharge pipe 43. A second valve 45 is provided on the surface of the discharge pipe 44. A sand guide ring 46 is fixedly installed on the inner bottom wall of the sand storage frame 41. The discharge end of the sand guide ring 46 is fixedly connected to the top feed end of the sand discharge pipe 43. The material of the spiral filter tube 42 is PP cotton.

[0043] Specifically, the sediment water filtered by the sand and gravel flows into the interior of the spiral filter tube 42. As the spiral filter tube 42 rotates, it provides spiral force and rotational centrifugal force, which controls the internal sediment water to be thrown out of the spiral filter tube 42 and enter the interior of the sedimentation barrel 31. The sand remains in the spiral filter tube 42 and enters the interior of the sand storage frame 41 for storage. During the sand discharge operation, the second valve 45 is opened and the discharge operation is performed under the guidance of the sand guide ring 46.

[0044] The top of the sand storage frame 41 is fixedly connected to the bottom end of the spiral filter tube 42, and the top inner wall of the sedimentation barrel 31 is threadedly connected with a guide ring 47. The discharge end of the guide ring 47 is rotatably connected to the feed end of the spiral filter tube 42 through a bearing, and a second pulley 48 is fixedly installed on the top arc surface of the spiral filter tube 42.

[0045] Specifically, the arrangement of the guide ring 47 facilitates the rapid flow of sediment water after the gravel is filtered into the interior of the spiral filter tube 42 .

[0046] In order to connect the driving mechanism 5 and simultaneously realize the driving operation of the first filtering and screening mechanism 3 and the second filtering and screening mechanism 4; the connecting driving mechanism 5 includes an installation box 51 and a driving motor 52, and the installation surface of one side of the installation box 51 is fixedly installed with the arc surface of the sedimentation barrel 31, and the installation surface of the driving motor 52 is fixedly installed with the inner wall of the installation box 51, and the output shaft of the driving motor 52 is fixedly installed with a power shaft 53 through a coupling, and the arc surface of the power shaft 53 and one end of the power shaft 53 are fixedly installed with a third pulley 54, and the groove of the third pulley 54 at the top and the groove of the first pulley 38 are both transmission-connected with the first transmission belt 55, and the groove of the third pulley 54 at the bottom and the groove of the second pulley 48 are both transmission-connected with the second transmission belt 56, and the arc surface of the sedimentation barrel 31 and the arc surface of the drive mounting ring 32 are both provided with avoidance grooves 57, and the inner walls of the two avoidance grooves 57 are respectively slidably plugged into the surface of the first transmission belt 55 and the surface of the second transmission belt 56.

[0047] Specifically, two powers are provided simultaneously by one power source to respectively control the transmission of the first conveyor belt 55 and the second conveyor belt 56, thereby simultaneously controlling the effects of the working filtering and screening operations of the first filtering and screening mechanism 3 and the second filtering and screening mechanism 4, thereby avoiding the cost of excessive use of power sources due to multiple power source drives, and the high repair cost due to damage caused by excessive use.

[0048] In order to locate the sedimentation tank 2 on one side of the equipment support leg 1, a solidification mechanism 6 and an automatic extraction mechanism 7 are provided inside the sedimentation tank 2. The solidification mechanism 6 realizes the solidification operation of the mud and water inside the sedimentation tank 2. The solidification mechanism 6 includes selecting materials for the solidification operation, using cement, quicklime and fly ash. The solidification operation discharges the mud and water inside the sedimentation tank 2 through the outlet pipe 34, adds the selected solidification materials to the mud and water, and adds cement, quicklime and fly ash to the mud and water in the sedimentation tank 2, and precipitates and solidifies inside the sedimentation tank 2.

[0049] Specifically, the filtered muddy water is allowed to settle inside the sedimentation tank 2 while auxiliary solidification materials are added to enhance the solidification of the mud in the muddy water, making it easier to separate the mud from the water. The separated water can then be recycled to avoid wasting resources.

[0050] In order for the automatic extraction mechanism 7 to realize the automatic extraction operation of the soil after the solidification operation of the solidification mechanism 6, the automatic extraction mechanism 7 includes a guide rail 71 and an installation top plate 72. The four guide rails 71 are respectively arranged at the four corners of the sedimentation tank 2 and are fixedly installed with the inner wall of the sedimentation tank 2. The surface of the guide rail 71 is slidably plugged with a slider 73. The surfaces of the four sliders 73 are fixedly installed with a holding frame 74. The holding frame 74 is composed of a U-shaped frame woven from a wire mesh with gauze placed flat inside. A cleaning sealing door 75 is provided on one side of the holding frame 74.

[0051] Specifically, the setting of the guide rail 71 and the slider 73 facilitates the smooth operation of the holding frame 74 during the extraction operation, and can achieve a quick extraction effect. A cleaning sealing door 75 is set on one side of the holding frame 74. When controlling the extraction of the holding frame 74, it is convenient to open the cleaning sealing door 75 to quickly clean the solidified soil, avoiding the existing use of an excavator to dig and clean the soil, which has a slow cleaning effect and high cost.

[0052] The tops of the four guide rails 71 are fixedly mounted around the bottom of the mounting top plate 72. The top of the mounting top plate 72 is fixedly mounted with a fixing seat 76 and a bearing seat 77. The four bearing seats 77 are arranged in two groups. The inner rings of the bearings of the two bearing seats 77 in each group are fixedly mounted with a winding shaft 78. Winding wheels 79 are fixedly mounted at both ends of the winding shaft 78. The surface of the winding wheel 79 is wound with a steel wire rope 710. The bottom ends of the four steel wire ropes 710 are fixedly mounted on the tops of the four sliders 73 respectively. There are wire holes 711 around the periphery, and the inner walls of the wire holes 711 are slidably plugged into the surface of the wire rope 710. The fourth pulley 712 is fixedly installed in the middle of the arc surface of the two winding shafts 78. A rotating motor 713 is fixedly installed on the top of the fixed seat 76. The output shaft of the rotating motor 713 is fixedly installed with a pulley shaft 714 through a coupling. A fifth pulley 715 is fixedly installed at one end of the pulley shaft 714. The groove of the fifth pulley 715 and the grooves of the two fourth pulleys 712 are both transmission-connected with a third transmission belt 716.

[0053] Specifically, during the extraction operation of the holding frame 74, the rotating motor 713 is used to control the winding wheels 79 on all sides to rotate the winding wire rope 710, thereby simultaneously controlling the winding operation of the four wire ropes 710, thereby controlling the extraction effect of the holding frame 74 leaving the sedimentation tank 2.

[0054] The present invention can quickly separate the mud discharged during the drilling of pile foundation construction, so as to separate gravel, silt, soil and water, and then realize the application of mud to projects such as construction access roads, fish pond filling or roadbed filling. It is both environmentally friendly and economical, greatly improving the construction image of the construction site, improving the mud disposal capacity, finding a practical method for project mud disposal, and improving the environmental and water protection level of the project; the filtered gravel and sand can be converted into concrete raw materials, rationally utilizing resources; waste mud is centrally processed to reduce the cost of mud transportation and disposal, and the solidified mud is used as roadbed filler to reduce the mileage of earthwork transfer, which is expected to reduce transportation costs by more than 30%.

[0055] Example 2

[0056] Reference Figure 1-Figure 7 A method for treating mud solidification treatment equipment in pile foundation construction, step 1: mud discharged from the drilling hole during pile foundation construction is extracted through a pipeline and discharged into the interior of the filter protective cover 33, and the connection drive mechanism 5 is controlled to work so that the drive motor 52 rotates to drive the power shaft 53 to rotate, thereby driving the third pulley 54 to rotate, and the two third pulleys 54 respectively control the first transmission belt 55 and the second transmission belt 56 to transmit motion;

[0057] The first transmission belt 55 drives the first pulley 38 to rotate during the transmission motion, thereby controlling the rotation of the rotating shaft 37, and further controlling the screening cover 39 to rotate eccentrically with the axis of the rotating shaft 37 as the center, so that the filter holes 310 on the surface of the screening cover 39 are used to filter the gravel in the mud, so that the gravel remains on the top of the lower disc of the screening cover 39, and the filtered mud flows into the interior of the drive mounting ring 32;

[0058] The second transmission belt 56 drives the third pulley 54 to rotate during the transmission movement, thereby controlling the spiral filter tube 42 to perform a circular motion. The filtered mud flows into the interior of the spiral filter tube 42 under the guidance of the guide ring 47. Under the action of the rotation of the spiral filter tube 42, the mud flowing in is thrown out of the muddy water under the spiral force and the rotating centrifugal force, so that the crushed sand flows into the sand storage frame 41 at the bottom for storage. When the sand discharge operation is required, the second valve 45 is opened to control the crushed sand to flow out of the sand storage frame 41 under the guidance of the sand guide ring 46;

[0059] Step 2: The muddy water after filtering out the sediment enters the sedimentation barrel 31. The muddy water is discharged through the outlet pipe 34 by opening the first valve 35 and flows into the sedimentation tank 2. Cement, quicklime and fly ash are added to the sedimentation tank 2 to mix with the muddy water and solidify it.

[0060] Step 3: After solidification and sedimentation for a period of time, the solidified mud and water are separated. The water is located above the mud. The separated water is extracted through a water pipe and used again for pile foundation construction drilling.

[0061] Step 4: After settling for a period of time, the rotating motor 713 is used to drive the pulley shaft 714 to rotate, thereby controlling the rotation of the fifth pulley 715. Under the transmission of the third transmission belt 716, the winding shafts 78 on both sides are controlled to rotate, driving the winding wheels 79 at both ends to rotate and tighten, thereby controlling the steel wire rope 710 wound on the surface to be wound and tightened, driving the lower holding frame 74 to move upward, thereby controlling the solidified mud to be lifted to the top of the sedimentation tank 2 for cleaning and transportation. During the cleaning and transportation operation, the cleaning sealing door 75 on one side of the holding frame 74 is opened to enable the solidified mud to be quickly cleaned;

[0062] Step 5: After the solidified mud is cleaned, the rotary motor 713 is controlled to reverse, thereby controlling the winding wheel 79 to release the wire rope 710, and the frame 74 moves downward under its own weight to reset, waiting for the next advance operation.
