[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments: Figure 1 This is a schematic diagram showing the structure of the device with the lid open.

[0023] Figure 2 This is a schematic diagram viewed from above.

[0024] Figure 3 This is a schematic diagram of the overall structure. Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application. Example 1 like Figure 1-3 As shown: A mud circulation device, comprising: 1. Modular mud circulation tank The modular mud circulation tank is the core component of this device, and it consists of the following parts: Primary sedimentation tank: This is the first part that the sludge reaches after entering the circulation tank, and it is used for the initial sedimentation of larger solid particles.

[0026] Secondary sedimentation chamber: The slurry after being treated in the primary sedimentation chamber flows into this chamber for further sedimentation of smaller solid particles.

[0027] Slurry preparation / final settling tank: The slurry undergoes final settling and adjustment in this tank to ensure that the consistency and quality of the slurry meet the construction requirements.

[0028] Each compartment is connected by partitions and filters to ensure that the mud is effectively filtered during its flow.

[0029] 2. Roof and photovoltaic energy harvesting system The top cover is designed for quick assembly and disassembly, facilitating transportation and installation. Made of photovoltaic material, the top cover not only provides noise reduction but also collects solar energy. The electricity collected by the photovoltaic panels is connected to a control unit via wires, which drives the various electrical components of the device.

[0030] like Figure 2As shown: The top cover is designed for quick assembly and disassembly based on the size of the circulation pool. The frame has pre-drilled holes for a sound-absorbing device. The cover plate consists of a row of hollow sound-absorbing tubes made of photovoltaic material, reducing noise while also collecting electrical energy. This is particularly suitable for remote mountainous areas and places with inconvenient power supply. The linkage controller contains a photovoltaic energy storage box, which can be used as a battery start-up device during initial construction. The photovoltaic area of ​​the entire cover plate is sufficient to support the operation of the equipment. Each component responds to the linkage controller via a linkage signal module, enabling integrated operation of the linkage controller, including (cover plate movement, slurry stirring, mud pumping, starting the drying device, and mud data feedback).

[0031] 3. Interlocking controller and photovoltaic energy storage box The linkage controller is the brain of the entire system, responsible for coordinating the operation of all components. It has a built-in photovoltaic energy storage tank, allowing the equipment to be started via batteries during initial construction. The controller automatically adjusts the consistency of the mud and starts the drying device, etc., by receiving data from sensors.

[0032] 4. Integrated drying unit The integrated drying unit located at the bottom of the pulping tank is activated after construction is completed to mechanically dry and solidify waste materials such as pulp residue and drilling cuttings. The dried waste materials can be mixed with a solidifying agent to achieve the reuse of solid waste.

[0033] 5. Sensor and signal linkage module Sensors are installed inside the slurry mixing tank to monitor the consistency, level, density, and sand content of the slurry. This data is transmitted to the linkage controller via a signal linkage module for intelligent control.

[0034] 6. Grouting pumps and piping systems The grouting pump is connected to the slurry preparation tank to pump the adjusted mud to the construction site. The grouting pipeline and the return pipeline are used for transporting and recovering the mud, respectively. The return pipeline connection can be enlarged to allow all the mud to flow into the return pipeline, and the mud containing suspended bottom drilling cuttings can be recovered using the casing guide port.

[0035] 7. Cover plate transmission device and sliding track The cover plate transmission device is used to control the movement of the top cover, allowing it to slide on the sliding track for easy maintenance and repair.

[0036] Working principle: Mud preparation: Mud is prepared in a mud preparation chamber and stirred to the desired consistency by a vortex fan.

[0037] Slurry pumping: Start the grouting pump and transport the slurry to the construction site through the grouting pipeline.

[0038] Mud recycling: The mud at the construction site is returned to the primary sedimentation tank through the mud return pipeline.

[0039] Stepwise sedimentation: The slurry is filtered through primary and secondary sedimentation chambers in a stepwise manner.

[0040] Mud preparation: Adjust the mud consistency in the mud preparation chamber to ensure that it meets the construction requirements.

[0041] The sensors monitor the consistency, level, density, and sand content of the mud and transmit the data to the linkage controller.

[0042] Top cover control: The linkage controller controls the cover plate transmission device, so that the top cover moves on the sliding track.

[0043] The top cover uses a hollow sound-absorbing tube made of photovoltaic material, which reduces noise and collects solar energy.

[0044] Construction completed: After construction is completed, the integrated drying device is started to dry and solidify the slurry and drilling slag.

[0045] Data feedback: The linkage controller collects and processes data from the mud circulation tank to achieve intelligent control.

[0046] This invention utilizes a four-dimensional linkage of closed-loop circulation, waste recycling, digital monitoring, and ecological restoration. Its modular design allows for rapid assembly and disassembly, significantly improving site transfer efficiency. From the mud return pipeline to the primary sedimentation chamber, then through the secondary sedimentation chamber, and finally to the final sedimentation chamber (slurry preparation chamber), sedimentation occurs gradually, and filtration through a screen forms a closed loop. After on-site construction is completed, a drying device at the bottom of the equipment is activated to evaporate moisture and dry the mud and drilling cuttings. A solidifying agent is added to achieve the required strength for each construction section, thus achieving 100% resource recovery of waste. Each chamber is equipped with a touch sensor connected to an integrated module, displaying data such as mud density, viscosity, and sand content. This data is then transmitted to a linkage controller, which controls the mixing in the slurry preparation chamber, the opening of the photovoltaic cover, and the activation of the drying device. By monitoring data from each chamber, it can determine whether the mud consistency in the slurry preparation chamber meets the standards; if not, additional material is added. This elevates environmental control precision from "end-of-pipe treatment" to "zero-pollution throughout the process," aligning with national low-carbon requirements for engineering projects.

[0047] This application involves installing detachable circulation tanks, sedimentation tanks, grouting pipes, return slurry pipes, and various instrumentation and electronic equipment near the single or multiple pile groups to be constructed, in accordance with the current site layout and without affecting traffic. The mud circulation tank is assembled using 304 stainless steel modular units. It has three-stage treatment chambers: a primary sedimentation chamber, a secondary sedimentation chamber, and a final sedimentation chamber (which serves as a slurry preparation chamber at the beginning of construction and is used for proportioning adjustment during construction). The three sedimentation chambers are separated by partition plates, and the slurry is filtered layer by layer to the cyclone slurry preparation chamber under the action of filter screens and gravity head. A pump is installed outside the slurry preparation chamber and connected to the pumping pipeline for grout output.

[0048] like Figure 1 ,3 As shown: The circulating tank is equipped with a modular 304 stainless steel tank body and a tongue-and-groove anti-seepage sealing strip design. A reinforced perimeter fence is installed around the outside of the tank at different heights to prevent mud leakage and environmental pollution caused by vibration or other factors. Mud is pumped into the tank through an upper pipe via a grouting pump. A grouting pressure gauge and valve are installed on the grouting pipeline connected to the pump. The grouting pump is mounted on a pump base. The return slurry pipeline connects to the slurry outlet at the working face. The connection of the return slurry pipeline can be enlarged to allow the slurry containing drill cuttings to flow back to the circulation tank. The drill cuttings generated during construction are filtered out through a primary sedimentation tank, a secondary sedimentation tank, and a slurry preparation tank. The slurry preparation tank provides slurry with sufficient viscosity to the main batching tank. Sensors installed in each tank monitor the current consistency of the slurry. If the consistency does not meet the target, the slurry preparation tank is used for batching to achieve the required proportions. The slurry is then injected through the grouting pipe to ensure that the consistency remains excellent, greatly improving the quality of hole cleaning. At the bottom of the circulation tank, there is an integrated drying device that mechanically dries the slurry, drill cuttings, and other waste materials after construction, solidifying and refining them. The solidified waste is then mixed with a solidifying agent that meets the load-bearing capacity and strength requirements of various construction projects, allowing the waste slurry to be reused as solid waste. In addition, a maintenance platform is provided on one side of the slurry circulation device for easy inspection by staff.

[0049] To achieve green construction and meet low-carbon requirements, dust suppression and noise reduction integrated technology is adopted. A negative pressure dust collection device is installed on the top cover of the circulating pool, which is linked to the atomizing spray system. The variable frequency mud pump is equipped with a soundproof cover and a shock-absorbing base. The noise reduction cover material of this patent is photovoltaic material, but its shape imitates the soundproof device. Therefore, it can both reduce noise and collect electrical energy, which is connected to the linkage controller through wires.

[0050] This application addresses environmental issues during construction by using a detachable circulation tank and slurry inlet / outlet system. It enhances the integration of mud processing, makes mud parameters transparent, reduces borehole inspection time, improves site transfer efficiency, and emphasizes environmentally friendly and green construction. It also supports recycling technology, enabling the secondary use of drill cuttings and mud. The mud circulation tank's hatch cover design incorporates noise reduction, ensuring controllable noise. The use of a quick-detachable circulation tank makes environmental pollution controllable, safety controllable, and site enclosure less manpower investment. It eliminates the management costs of mud tanks in traditional processes, saving money.

[0051] Example 2 A mud circulation device is designed and customized according to the actual construction needs for circulating mud volume. The mud circulation tank adopts stainless steel unit modules and is divided into compartments, including a primary sedimentation tank, a secondary sedimentation tank, and a mud preparation tank (each compartment is equipped with sensors). The mud preparation tank is equipped with a vortex fan. A photovoltaic cover is installed on the top of the device to collect electrical energy and integrate it into a photovoltaic energy storage box. The photovoltaic cover moves through a transmission device, linking the atomizing spray system and the variable frequency mud pump, which is equipped with a soundproof cover and a shock-absorbing base (made of HDPE material with a certain degree of hardness). The entire system includes an intelligent monitoring unit. A grouting recorder and pressure gauge assembly are installed on the top of the grouting pipeline. Its function is to control the accuracy of parameters, monitor the flow rate and pressure in real time, and calculate the water head height, i.e., the hole depth, by observing the grouting recorder (including the pressure gauge) and the mud specific gravity in combination with the drill rod length. Sensors are installed in each compartment to dynamically detect the mud specific gravity value, and the data is connected to the equipment and displayed on the linkage controller through electromagnetic signals. The mud quality is adjusted based on the reflected data alarm.

[0052] The method of using the above device is as follows: Equipment process flow: 1. Turn on the power to prepare mud → 2. During operation, the photovoltaic cover plate collects energy and enters the battery (the battery and control box are integrated) → 3. Start the pump → 4. Inject mud → 5. Receive mud through the return pipe → 6. Primary sedimentation → 7. Secondary sedimentation → 8. Mud preparation chamber (the tertiary sedimentation chamber meets the normal mud consistency) → 9. The grouting pump pipeline connects to the mud preparation chamber to pump mud → 10. Operation completed → 11. Dry the drill cuttings at the bottom of the chamber → 12. Remove the surrounding barriers and reuse the drill cuttings (1) This patent is based on mud control and supplemented by electronic components in each compartment to detect parameters such as mud density, viscosity, sand content, liquid level, and grouting pressure. The mud is collected through the return pipe and enters each compartment, and is gradually settled and filtered before flowing back to the pulp preparation compartment; (2) Before assembling the equipment, the ground should be leveled. If the ground is wet and soft and the equipment cannot be leveled, the ground should be replaced or hardened before assembling the circulating pool.

[0053] (3) Based on the design drawings, geological survey data and site layout, a detachable mud circulation tank is constructed. The mud circulation tank adopts a 304 stainless steel unit module + tongue and groove rubber water-stop strip sealing design to prevent mud leakage from polluting the soil and groundwater and causing environmental pollution and damage. The mud circulation tank adopts a compartmentalized design, namely a primary sedimentation tank, a secondary sedimentation tank and a mud preparation tank. In order to achieve green construction and meet the low-carbon requirements, photovoltaic power generation technology is adopted. A row of photovoltaic tubes is set on the top cover of the circulation tank, which is shaped like a sound-absorbing tube, which can both reduce noise and generate electricity. The photovoltaic cover plate is designed with a transmission device that can be opened by a linkage controller.

[0054] (4) The grouting pipe and the return grouting pipe are connected in the circulation pool. The grouting pipe is connected to the grouting chamber in the circulation pool and the grouting pressure pump pumps the grout. The return slurry pipe is connected to the primary sedimentation chamber in the circulation pool. Through the secondary sedimentation chamber, the drilling cuttings are filtered out step-by-step by gravity and through the filters installed in each chamber, ensuring that the sand content of the mud meets the specifications. Excessive sand content exacerbates wear and tear on the mud equipment and reduces its wall-protecting performance. The circulation pool's chambers are divided to create a height difference in the liquid level, achieving a gradual filtration effect. A grouting recorder (pressure gauge) is installed at the connection point of the grouting pipeline to monitor grouting pressure, flow rate, and other construction parameters at any time. The other end of the return slurry pipe is connected to the casing guide port. The first section of the return slurry pipe can be enlarged to allow all the mud to flow into the return slurry pipe. The casing guide port is used to recover the mud containing suspended drilling cuttings from the bottom of the borehole. The return slurry pipe is designed for gravity flow, relying on the slope to return the mud back to the circulation pool. Sensors are installed in each chamber of the circulation pool to measure the consistency of the suspended cuttings slurry and obtain indicators such as sand content from the side. If the measured data exceeds the normal range, the trigger controller will automatically issue a warning.

[0055] (5) Preliminary construction stage. The slurry mixing chamber uses a vortex fan to rotate and stir the slurry. After the design ratio is reached as displayed on the linkage controller, the slurry is pumped. For waste slurry treatment: After the construction is completed, the integrated drying device is started to evaporate the water and leave dry drill cuttings mud slurry. The mud cake produced is used for secondary utilization such as roadbed filling.

[0071] Real-time monitoring of mud parameters and adjustment of feed ratio in the mud preparation silo based on data feedback ensure mud quality.
