[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] The mud solidification system includes a wind-solar complementary self-powered system, an electro-osmosis well point dewatering system, a mud pool system, and a well point pipeline support system. Figure 1 As shown, the wind-light complementary self-powered system includes a solar photovoltaic battery group 1, a solar controller 2, a wind generator group 3, a wind power controller 4, an inverter 5, a ballast 6, an intelligent management controller 7, a large-capacity battery group 8, and a power output terminal 9. The wind generator group 3, the solar photovoltaic generator group 1 and other facilities are arranged in an open area without obstructions, and the components are effectively connected through cables. The solar photovoltaic panel and the wind generator group 3 are respectively arranged in the sunny place and upwind direction of the site. According to the overall power grid load of generation, supply and storage, the solar controller 3, the wind power controller 4, the inverter 5, the ballast 6, the intelligent management controller 7, and the large-capacity battery group 8 are connected by appropriate cables. Since solar power generation is direct current and wind power generation is alternating current, and the large-capacity battery stores electrical energy and intelligently stores direct current, when the solar photovoltaic battery group 1 generates electricity to directly power the self-priming pump 20, it needs to be converted into alternating current through the inverter 5. When the wind generator group 3 generates electricity and stores it in the large-capacity battery group 8, it needs to convert the alternating current into direct current through the ballast 6 and then store it. By setting up a solar photovoltaic battery group 1 and a wind turbine generator group 3, the complementarity of wind energy and solar energy is utilized to avoid the influence of seasons and day and night on the stability of power generation. By setting up an inverter 5, a ballast 6, and an intelligent management controller 7, the intelligent control and conversion of AC and DC power of photovoltaic power generation and wind power generation can be realized, and the electric energy can be effectively and smoothly transmitted between the three modules of "generation, supply, and storage".

[0018] like Figure 2 As shown, the electroosmosis well point dewatering system includes an anode conductor 10, a cathode well point pipe 11, a perforated bottom plate 12, a filter tube 13, a check valve 15, a connecting elbow 18, a drain pipe 19, and a self-priming pump 20. The main body of the cathode well point pipe 11 is a double-layer structure, including a UPVC pipe 14 as an inner water absorption layer and a galvanized thin steel round pipe 16 wrapped in an outer layer. After the connecting wires of the anode conductor 10 and the cathode well point pipe 11 are energized, the outer galvanized round pipe 16 wrapping layer of the cathode well point pipe 11 will act as a cathode and play a conductive role, so that the silt layer or solid particle species formed after the mud is precipitated and the water molecules with positive charges gather toward the cathode well point pipe 11, and the inner UPVC pipe 14 acts as a water absorption channel, and under the action of the self-priming pump 20, the water is discharged into the main water pipeline 37.

[0019] Use drilling equipment to drill holes in the mud sedimentation tank 25 to be solidified and bury the anode conductor 10 and the cathode well point pipe 11. The inner tube body of the cathode well point pipe 11 is provided with a check valve 15 and a filter tube 13. The check valve 15 ensures that water can only flow out in one direction to prevent backflow. The anode conductor 10 is arranged around the well point pipe 11, usually using a metal rod or plate with good conductivity, and is connected to the cathode well point pipe 11 through a wire to form an electric field. The cathode well point pipe 11 and the anode conductor 10 are arranged in a plum blossom shape, and their top ends are arranged on the well point pipe positioning frame beam 35.

[0020] The wind-solar integrated self-powered system is turned on to provide power support for the entire electro-osmosis process. At the same time, when there is surplus wind-solar power generation, the power generation system charges the large-capacity battery pack 8. When the power generation is insufficient, the large-capacity battery pack 8 outputs power to the outside. A DC voltage is applied between the cathode well point tube 11 and the anode conductor 10 to form an electric field, which causes the moisture in the soil to migrate to the cathode well point tube 11 under the action of the electric field.

[0021] like Figure 3-5 As shown, the mud pool system includes a brick mud pool wall 24, a mud sedimentation tank 25, a slurry making tank 26, a slurry storage tank 27, a first clearing tank 28, a second clearing tank 29, a slurry discharge pipe 30, a filter screen 31, and a slurry discharge pipe cover 32. The mud sedimentation tank 25 and the first clearing tank 28 are connected by a slurry discharge pipe 30. A slurry discharge pipe cover 32 and a filter screen 31 are provided on one side of the slurry discharge pipe 30 connected to the mud sedimentation tank 25. The slurry discharge pipe cover 32 can close the slurry discharge pipe 30 at any time. The filter screen 31 can filter out the solid waste in the relatively diluted mud in the upper part of the mud sedimentation tank 25.

[0022] The mud to be solidified is naturally precipitated in the mud sedimentation tank 25, and the mud and solid particles are initially separated. The mud with a relatively low concentration is discharged into the first clearing tank 28 through the slurry discharge pipe 30 and then continues to be naturally precipitated. Then it flows into the second clearing tank 29 for secondary precipitation. After the treated mud is close to water, it is discharged into the pulping tank 26 for the preparation of fresh mud. The sedimentation and circulation of the mud tank system are used to perform preliminary separation and solidification treatment on the solid and liquid parts of the mud. Secondly, combined with the use of the electroosmosis well point dewatering system, the solid particles of the mud in the mud sedimentation tank 25 are further drained and solidified. The galvanized thin pipe wrapped by the well point pipe is used as the cathode, and the 25mm steel bar is used as the anode. Direct current is passed to generate electroosmosis phenomenon and electroosmosis drainage is performed, so that the water in the solid particles after the mud is precipitated is sucked into the drainage pipe 19 through the self-study water pump 20, and then discharged into the first clearing tank through the drainage main pipe 37. By implementing the above two methods simultaneously, the mud solidification treatment is realized quickly and efficiently.

[0023] like Figure 4-5 As shown, the well point pipeline support system includes a pool side channel steel cushion beam 33, a well point pipe support beam 34, and a well point pipe positioning frame beam 35. A circle of channel steel cushion beams 33 are laid around the top of the pool wall of the mud sedimentation tank 25, and the channel steel cushion beams 33 use 20# channel steel. Then, well point pipe support beams 34 are laid at intervals along the short side direction of the sedimentation tank, and the well point pipe support beams 34 use 20# channel steel. Then, well point pipe positioning frame beams 35 are laid along the long side direction of the sedimentation tank, and the well point pipe positioning frame beams 35 use 14# channel steel. The well point pipe positioning frame beams 35 are opened to arrange the anode conductor 10 and the cathode well point pipe 11, and the arrangement form adopts a plum blossom arrangement.

[0024] After the construction of the mud sedimentation tank 25 is completed, the mobile trestle platform 36 is first processed and set up for the installation and construction of the components of the support system and the electro-osmosis well point dewatering system. The well point pipeline support system cooperates with the mobile trestle platform 36 spanning the mud sedimentation tank 25 to achieve coverage of the working area of ​​the entire sedimentation tank.

[0025] The construction process of the solidified mud system is as follows: 1. Preparation: According to the project scale and site conditions, the amount of mud solidification engineering is preliminarily determined to determine the excavation location and size of the mud sedimentation tank 25, the first clearing tank 28, the second clearing tank 29, and the mud storage tank 27. The excavation depth of each type of mud pool should be 2 to 3m, and the mud sedimentation tank 25 should be arranged in a narrow and long shape to avoid the span of the supporting beam being too large. The mud pool wall is treated by brickwork + mortar plastering. The mud sedimentation tank 25 and the first clearing tank 28 are connected by a slurry discharge pipe 30, which should be located 50cm below the top of the red cliff.

[0026] 2. Processing and installation of the support beam system: [20 channel steel is laid out around the mud sedimentation tank 25 as the pool side channel steel cushion beam 33, in a closed circular arrangement, and fixed to the hardened ground with steel bar heads or expansion bolts. On the supporting crossbeam, I20a beams are arranged at intervals of 2m to support the longitudinal well point pipe positioning frame beams. The well point pipe positioning frame beams are made of [14 steel sections with a horizontal spacing of 0.5m. Before installation, holes are pre-drilled according to the positions of the cathode well point pipe 11 and the anode conductor 10. The hole diameter at the anode conductor 10 is 30mm, and the hole diameter at the cathode well point pipe 11 is 60mm, with a spacing of 0.5m.

[0027] 3. Processing and installation of mobile trestle platform: The mobile trestle is processed with steel sections. The width of the trestle is 60cm. I20a steel sections are used as main beams on the left and right sides, and [20 steel sections are used as cross beams in the horizontal direction, with a spacing of 50cm. Patterned steel plates are laid on top. Railings are arranged on both sides of the trestle. The railing columns are 1.2m high and [14 channel steel is used. Then 48*3.5 steel pipes are used as longitudinal horizontal railings, a total of two, with a vertical spacing of 0.6m. A 0.2cm thick steel plate is set at the bottom of the guardrail as a skirting board with a height of 18cm. Two-way wheel groups are set at both ends of the trestle, which can slide in a straight line one after another. The trestle is processed in the open space at one end of the mud sedimentation tank, and after processing, it spans over the mud pool.

[0028] 4. Processing and installation of anode conductor 10 and cathode well point pipe 11: First, determine the length of anode conductor 10 and cathode well point pipe 11 according to the depth of the mud pool, and then process anode conductor 10 and cathode well point pipe 11. Anode conductor 10 adopts 25mm steel bar, and the inner pipe of cathode well point pipe 11 adopts UPVC pipe 14 with a diameter of 40, and outer galvanized thin steel round pipe 16. UPVC pipe 14 has the advantages of light weight and simple and quick connection, which is conducive to on-site production and installation. Using the temporary trestle as the working platform, fix the anode conductor 10 and cathode well point pipe 11 on the positioning frame beam, and then lay a drainage branch pipe along the direction of the supporting crossbeam. The opening of the branch pipe is connected to the cathode well point pipes on both sides through a connecting elbow. A self-priming pump 20 is set at the end of each branch pipe, and the water outlet of the self-priming pump 20 is connected to the main drainage pipe 37.

[0029] 5. Installation of wind-photovoltaic energy "generation, supply and storage" system: According to the local climate conditions, the solar sunshine, wind direction and wind force conditions in the season when this plan is implemented are estimated in the area where the project is located, and the number and power of water pumps, the number of anode conductors, and the number of cathode well point pipes in the electro-osmosis well point dewatering system are combined. The appropriate number and specifications of solar photovoltaic panels, wind turbines, battery packs, etc., and matching inverters, ballasts, intelligent controllers and other related equipment are selected, and effectively connected with cables. After the system is installed, it is connected and debugged with the electro-osmosis well point dewatering system.

[0030] 6. Overall operation of the system: Connect the wind-photovoltaic energy "generation, supply and storage" system with the electro-osmosis well point dewatering system, and close the switch. The electro-osmosis drainage system is running, the water in the solid particles of the mud sediment is quickly discharged, and the cathode well point pipe is continuously pumped to accelerate the solidification of the mud. When the electro-osmosis well point dewatering system is closed and not running, the wind-solar power generation system continues to charge the large-capacity battery.

[0031] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
