Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a leveling device and leveling method for a containerized flywheel energy storage system. Background Technology

[0002] Flywheel energy storage refers to an energy storage method that uses an electric motor to drive a flywheel to rotate at high speed, and then uses the flywheel to drive a generator to generate electricity when needed. The flywheel itself is the core component of the flywheel energy storage system, and its function is to strive to increase the rotor's ultimate angular velocity, reduce the rotor's weight, and maximize the energy storage capacity of the flywheel energy storage system.

[0003] Containerized flywheel energy storage devices represent a modular and containerized implementation of flywheel energy storage technology. Their internal structure and transportation / installation design must balance high energy density, operational stability, and engineering feasibility. During installation, the flywheel energy storage device is integrated into a container primarily to ensure the equipment's stability and safety.

[0004] Because the flywheel system and other equipment inside the container are not evenly distributed, long-term operation can easily lead to uneven settlement and serious tilting. When tilting occurs, the existing solution is usually to temporarily shut down the flywheel system, use a truck crane to lift the container as a whole, and then use high-rigidity materials such as steel plates to level it. Since a single container is large in volume and weighs tens of tons, the actual work process is very troublesome, requires a lot of manpower and resources, and is prone to damage to the steel plates, affecting the leveling effect. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects and problems of inconvenient leveling and poor leveling effect in the prior art, and to provide a leveling device and leveling method for containerized flywheel energy storage systems that is convenient to level and has a better leveling effect.

[0006] To achieve the above objectives, the technical solution of the present invention is: a leveling device for a containerized flywheel energy storage system, comprising: a base plate, multiple lifting components, a limiting component, a monitoring unit, and a control unit. The base plate is horizontally arranged and its lower side is installed on a concrete foundation via embedded parts. The multiple lifting components are evenly distributed on the upper side of the base plate. The output ends of the multiple lifting components are connected to a top plate for receiving containers. The limiting component is slidably connected to the side of the top plate in the vertical direction via a sliding component. The monitoring unit is connected to the top plate, the limiting component, and the flywheel energy storage system. The control unit is connected to the monitoring unit and the multiple lifting components.

[0007] Multiple lifting components are used to lift and lower different positions of the top plate, respectively;

[0008] The limiting component is used to vertically limit the side of the container;

[0009] The monitoring unit is used to monitor the force on the limiting component, monitor various parameters of the top plate, and monitor various parameters of the flywheel energy storage system.

[0010] The control unit is used to issue early warnings based on various parameters of the flywheel energy storage system monitored by the monitoring unit; to obtain the tilt status of the top plate based on the force of the limit component and various parameters of the top plate; and to control the corresponding lifting component to lift or lower the top plate to level it based on the tilt status of the top plate.

[0011] The embedded component includes multiple embedded steel bars, which are arranged in an array. The upper end of each embedded steel bar is connected to the lower side of the base plate, and the lower end of each embedded steel bar is inserted into the concrete foundation. An embedded groove is provided on the upper side of the concrete foundation, and the base plate is embedded in the embedded groove.

[0012] Multiple support columns are provided on the lower side of the base plate, and the multiple support columns are arranged one-to-one with the multiple pre-embedded steel bars. The upper end of the support column is connected to the lower side of the base plate, and the lower end of the support column is inserted into the concrete foundation. A cavity is opened at the upper end of the support column, and the lower end of the pre-embedded steel bar is inserted into the cavity. A liquid storage box is filled in the gap between the pre-embedded steel bar and the support column. The liquid storage box is filled with adhesive and is made of pressure diaphragm material.

[0013] The number of the multiple lifting components is four, and the four lifting components are installed at the four top corners of the base plate. The lifting components include a jack, a steel ball, a connecting plate, an external controller tube, and a controller. The jack is installed on the upper side of the base plate, and the output end of the jack has a first rolling groove. The connecting plate is connected to the lower side of the base plate, and the lower side of the connecting plate has a second rolling groove. The steel ball is rotatably connected to the first rolling groove and the second rolling groove. One end of the external controller tube is connected to the input end of the jack, and the other end of the external controller tube is connected to the controller. The controller is connected to the control unit.

[0014] The limiting component includes four edge steel plates, which are arranged vertically around the top plate.

[0015] The sliding assembly includes four fixing buckles, which are arranged one-to-one with the edging steel plate. Each fixing buckle includes two L-shaped plates, which are arranged symmetrically. The edging steel plate is slidably connected between the two L-shaped plates. The vertical part of the L-shaped plate is connected to the side of the top plate. The inner sidewall of the L-shaped plate is attached to the outer edge of the edging steel plate. The outer side of the L-shaped plate is provided with a positioning hole, and the outer side of the edging steel plate is provided with a mounting hole that matches the positioning hole. The positioning hole and the mounting hole are internally threaded with fixing bolts.

[0016] The monitoring unit includes a displacement sensor, a tilt sensor, a pressure sensor, a temperature and humidity sensor, and a vibration sensor. The control unit is connected to the displacement sensor, tilt sensor, pressure sensor, temperature and humidity sensor, and vibration sensor. The displacement sensor and tilt sensor are connected to the top plate. The pressure sensor is connected to the limiting component. The temperature and humidity sensor and vibration sensor are connected to the flywheel energy storage system.

[0017] The displacement sensor and tilt sensor are used to measure the displacement change and tilt angle of the top plate, respectively.

[0018] The pressure sensor is used to measure the pressure value of the limiting component;

[0019] The temperature and humidity sensor and vibration sensor are used to measure the ambient temperature and humidity of the flywheel energy storage system and the vibration frequency and amplitude of the flywheel energy storage system.

[0020] The control unit is used to determine whether the flywheel energy storage system is abnormal based on the ambient temperature, humidity and vibration frequency amplitude, and to repair the flywheel energy storage system in advance according to the abnormal situation. It can also determine the tilt status of the top plate based on displacement changes, tilt angle and pressure value.

[0021] A leveling method for a leveling device used in a containerized flywheel energy storage system, the leveling method comprising the following steps:

[0022] Step 1: Place the container on the roof, monitor the various parameters of the roof using the monitoring unit to obtain the tilt status of the roof, and control the corresponding lifting components to lift the roof and level it.

[0023] Step 2: After leveling the top plate, control the sliding of the limiting components so that they abut against the side of the container;

[0024] Step 3: Monitor various parameters of the flywheel energy storage system, various parameters of the top plate, and the force value of the limit components through the monitoring unit. Obtain the tilt status of the top plate through the control unit and control the corresponding lifting components to lift and level the top plate.

[0025] The calculation of the tilt of the top plate by the control unit includes:

[0026] When all parameters of the flywheel energy storage system are normal, and the parameters of the top plate and the force value of the limit component exceed the set value, the tilt status of the top plate is calculated by displacement change, tilt angle and pressure value, and the corresponding lifting component is controlled to lift and level the top plate.

[0027] When all parameters of the flywheel energy storage system, the parameters of the top plate, and the force value of the limit component exceed the set value, the tilt status of the top plate is calculated by displacement change, tilt angle, and pressure value, and the corresponding lifting component is controlled to lift the top plate to level it. If the parameters of the flywheel energy storage system still exceed the set value, the flywheel energy storage system is repaired.

[0028] When the parameters of the flywheel energy storage system exceed the set values, and the parameters of the top plate and the limit components are normal, the flywheel energy storage system is repaired.

[0029] The embedded component includes multiple embedded steel bars arranged in an array. The upper ends of the embedded steel bars are connected to the lower side of the base plate, and the lower ends of the embedded steel bars are inserted into the concrete foundation. An embedded groove is provided on the upper side of the concrete foundation, and the base plate is embedded in the embedded groove. Multiple support columns are provided on the lower side of the base plate, and the multiple support columns are arranged in a one-to-one correspondence with the multiple embedded steel bars. The upper ends of the support columns are connected to the lower side of the base plate, and the lower ends of the support columns are inserted into the concrete foundation. A cavity is opened at the upper end of the support column, and the lower ends of the embedded steel bars are inserted into the cavity. A liquid storage box is filled in the gap between the embedded steel bars and the support columns. The liquid storage box is filled with adhesive, and the liquid storage box is made of pressure diaphragm material.

[0030] Once the control unit calculates the tilt of the top plate and controls the lifting assembly to lift it, leveling the top plate, a winch is placed at the lifting position of the lifting assembly. A grouting groove is excavated on the outside of the bottom plate, and the steel cable of the winch is connected to the bottom plate. The winch is then controlled to lift the bottom plate to the same height as the lifting assembly. During the lifting process, the liquid storage box is damaged by pressure, and the internal adhesive fills the cavity. At the same time, the already lifted lifting assembly is controlled to descend synchronously to keep the top plate horizontal. After the bottom plate is leveled, grout is injected into the grouting groove to fill the gaps. After the grout solidifies, the steel cable is removed, and the winch is taken out.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] 1. In this invention, a leveling device and method for a containerized flywheel energy storage system are disclosed. The base plate is connected and fixed to a concrete foundation. Since the base plate is horizontal, it can be used as a reference for subsequent leveling. A lifting assembly is used to raise or lower the top plate for leveling. After leveling, the container is installed. During subsequent use, the container is monitored in real time by a monitoring unit. If the container tilts, the lifting assembly can be used to raise the top plate for leveling. Because the container remains on the top plate during leveling, repeated lifting is unnecessary, preventing damage to the top plate. A limiting assembly is used to limit the container's movement after leveling, preventing lateral displacement and ensuring even stress distribution on the base plate, effectively preventing uneven stress on the base plate that could cause the container to tilt. Therefore, this invention offers convenient leveling and good leveling performance.

[0033] 2. In the leveling device and method for a containerized flywheel energy storage system of the present invention, by setting the embedded parts within the concrete foundation, the overall strength of the device can be effectively improved. Simultaneously, by setting support columns, when the base plate sinks, the elastic layer is compressed, and the embedded steel bars squeeze the liquid storage box, causing it to rupture. The adhesive inside the liquid storage box fills the cavity, and after leveling the base plate, the adhesive reinforces the embedded steel bars, further improving the overall strength of the device. Therefore, the present invention has high structural stability.

[0034] 3. In the leveling device and method for a containerized flywheel energy storage system of the present invention, jacks are installed at the four corners of the container to adjust its height and keep it level when the container is subjected to uncertain factors such as settlement, tilting, vibration, misalignment, or earthquakes. Steel balls are also installed to change the angle of the top plate when the jacks are raised, thereby achieving leveling. Therefore, the present invention is convenient to construct and has high reliability.

[0035] 4. In the leveling device and method for a containerized flywheel energy storage system of the present invention, a sliding edge steel plate is provided. After the container flywheel equipment is hoisted, the edge steel plate can be raised, aligning the mounting holes with the positioning holes and connecting and fixing them with fixing bolts. This allows the edge steel plate to be secured to the side of the container, effectively preventing lateral displacement of the container. The use of clips restricts the movement of the edge steel plate, allowing it to slide only up and down, and also assists in fixing the edge steel plate. Therefore, the present invention has a stable structure and good fixing effect.

[0036] 5. In the leveling device and method for a containerized flywheel energy storage system of the present invention, multiple sensors are set up to convert various monitored parameters into electrical signals, which can be identified and processed by the control unit. Simultaneously, since the sensors are also connected to the flywheel energy storage system, they can receive signals from the internal devices of the flywheel energy storage system, thereby facilitating the control unit to identify the electrical signals and analyze the actual status of the flywheel energy storage system to control the corresponding jacks to lift and level the top plate. Therefore, the present invention is convenient to use and has a high degree of intelligence.

[0037] 6. In the leveling device and method for a containerized flywheel energy storage system of the present invention, when the flywheel energy storage system malfunctions, the container tilt will further deepen. Therefore, by detecting various parameters of the flywheel energy storage system, early warning can be issued to avoid the need for repeated leveling after the top plate has been leveled due to the flywheel energy storage system malfunction. The displacement changes and tilt angles can be converted into the lifting distance of the jacks, making the lifting process more intuitive and rigorous. Therefore, the leveling process of the present invention is stable and the leveling effect is good. Attached Figure Description

[0048] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] Example 1:

[0050] See Figures 1 to 9 A leveling device for a containerized flywheel energy storage system includes: a base plate 3, multiple lifting components 4, a limiting component 5, a monitoring unit 8, and a control unit 9. The base plate 3 is horizontally arranged and its lower side is installed on a concrete foundation 1 via embedded parts 2. The multiple lifting components 4 are evenly distributed on the upper side of the base plate 3. The output ends of the multiple lifting components 4 are connected to a top plate 7 for receiving containers. The limiting component 5 is slidably connected to the side of the top plate 7 in the vertical direction via a sliding component 6. The monitoring unit 8 is connected to the top plate 7, the limiting component 5, and the flywheel energy storage system 10. The control unit 9 is connected to the monitoring unit 8 and the multiple lifting components 4.

[0051] Multiple lifting components 4 are used to lift and lower different positions of the top plate 7 respectively;

[0052] The limiting component 5 is used to vertically limit the side of the container;

[0053] The monitoring unit 8 is used to monitor the force on the limiting component 5, monitor various parameters of the top plate 7, and monitor various parameters of the flywheel energy storage system 10.

[0054] The control unit 9 is used to issue early warnings based on various parameters of the flywheel energy storage system 10 monitored by the monitoring unit 8; to obtain the tilt status of the top plate 7 based on the force of the limit component 5 and various parameters of the top plate 7; and to control the corresponding lifting component 4 to lift or lower the top plate 7 to level it based on the tilt status of the top plate 7.

[0055] In this embodiment, the interior of the container is used to store the flywheel energy storage system 10. An outer shell 11 connects the bottom plate 3 and the top plate 7. The outer shell 11, the bottom plate 3, and the top plate 7 together form a sealed cavity 12. The outer shell 11 can be made of a porous polyethylene film to ensure the entire device is relatively sealed. In use, the bottom plate 3 is first welded to the embedded part 2. Then, the embedded part 2 is embedded into the concrete foundation 1. The embedding depth depends on the actual foundation thickness, while ensuring the bottom plate 3 is level. The monitoring unit 8 then monitors whether the top plate 7 is level. If it is not level... The system controls the lifting assembly 4 to lift and lower the container. During the lifting process, the monitoring unit 8 monitors the levelness of the top plate 7 in real time. When the top plate 7 is level, the container is hoisted onto the top plate 7. Then, the limiting assembly 5 is controlled to slide, so that the limiting assembly 5 is engaged with the side of the container to limit the container. Then, the monitoring unit 8 monitors the force on the limiting assembly 5, the various parameters of the top plate 7, and the various parameters of the flywheel energy storage system 10 in real time and transmits them to the control unit 9. The control unit 9 controls the corresponding lifting assembly 4 to lift the container so that it remains level.

[0056] Example 2:

[0057] The basic content is the same as in Example 1, except that:

[0058] See Figures 2 to 5 The embedded component 2 includes multiple embedded steel bars 21 arranged in an array. The upper ends of the embedded steel bars 21 are connected to the lower side of the base plate 3, and the lower ends of the embedded steel bars 21 are inserted into the concrete foundation 1. An embedded groove 22 is provided on the upper side of the concrete foundation 1, and the base plate 3 is embedded in the embedded groove 22. Multiple support columns 23 are provided on the lower side of the base plate 3, and the multiple support columns 23 are connected to the multiple embedded steel bars 21. In a one-to-one arrangement, the upper end of the support column 23 is connected to the lower side of the base plate 3 through an elastic layer 26, and the lower end of the support column 23 is inserted into the concrete foundation 1. A cavity 24 is opened at the upper end of the support column 23, and the lower end of the pre-embedded steel bar 21 is inserted into the cavity 24. The gap between the pre-embedded steel bar 21 and the support column 23 is filled with a liquid storage box 25, which is filled with adhesive and is made of pressure film.

[0059] In this embodiment, the diameter of the pre-embedded steel bar 21 is 20mm. It is located at the bottom of the base plate 3 and is welded and fixed to the base plate 3. The length can be determined according to the foundation type and actual engineering conditions. It is embedded in the concrete foundation 1 during the foundation construction stage, which can increase the stability and stress of the pre-embedded steel bar 21. The upper end face of the base plate 3 is flush with the upper surface of the concrete foundation 1. During use, if the base plate 3 sinks, the pre-embedded steel bar 21 will squeeze the liquid storage box 25, causing the liquid storage box 25 to break. The adhesive inside the liquid storage box 25 will fill the cavity 24. After the base plate 3 is leveled, the pre-embedded steel bar 21 can be reinforced.

[0060] Example 3:

[0061] The basic content is the same as in Example 1, except that:

[0062] See Figure 1 and Figure 2 The number of the multiple lifting components 4 is four, and the four lifting components 4 are installed at the four top corners of the base plate 3. The lifting component 4 includes a jack 41, a steel ball 43, a connecting plate 44, an external controller tube 46, and a controller 47. The jack 41 is installed on the upper side of the base plate 3. The output end of the jack 41 has a first rolling groove 42. The connecting plate 44 is connected to the lower side of the top plate 7. The lower side of the connecting plate 44 has a second rolling groove 45. The steel ball 43 is rotatably connected to the first rolling groove 42 and the second rolling groove 45. One end of the external controller tube 46 is connected to the input end of the jack 41, and the other end of the external controller tube 46 is connected to the controller 47. The controller 47 is connected to the control unit 9.

[0063] In this embodiment, the jack 41 is an ultra-thin jack, which is small in size and has a strong lifting capacity. When the jack 41 needs to be adjusted, the control unit 9 sends a command to the controller 47. The controller 47 controls the external controller tube 42 to deliver hydraulic oil to the jack 41 for lifting and lowering. The principle can be referred to as the air supply pipe of an air pump. When the jack 41 is not in use, the external controller tube 46 can be removed from the controller 47.

[0064] Example 4:

[0065] The basic content is the same as in Example 1, except that:

[0066] See Figure 1 , Figure 6 , Figure 7 and Figure 8The limiting component 5 includes four edge steel plates 51, which are vertically arranged around the top plate 7. The sliding component 6 includes four fixing buckles 61, which are arranged one-to-one with the edge steel plates 51. Each fixing buckle 61 includes two L-shaped plates 611, which are symmetrically arranged. The edge steel plates 51 are slidably connected between the two L-shaped plates 611. The vertical part of the L-shaped plate 611 is connected to the side of the top plate 7. The inner sidewall of the L-shaped plate 611 is attached to the outer edge of the edge steel plate 51. The outer side of the L-shaped plate 611 is provided with a positioning hole 62. The outer side of the edge steel plate 51 is provided with a mounting hole 52 that matches the positioning hole 62. The positioning hole 62 and the mounting hole 52 are internally threaded with fixing bolts 63.

[0067] In this embodiment, after the top plate 7 is initially leveled, the four edge steel plates 51 are slid and brought into contact with the side of the container by sliding the edge steel plates 51. Then, the fixing bolts 63 are screwed into the positioning holes 62 and the mounting holes 52 to connect and fix the L-shaped plate 611 to the edge steel plates 51.

[0068] Example 5:

[0069] The basic content is the same as in Example 1, except that:

[0070] See Figure 9 The monitoring unit 8 includes a displacement sensor 81, a tilt sensor 82, a pressure sensor 83, a temperature and humidity sensor 84, and a vibration sensor 85. The control unit 9 is connected to the displacement sensor 81, the tilt sensor 82, the pressure sensor 83, the temperature and humidity sensor 84, and the vibration sensor 85. The displacement sensor 81 and the tilt sensor 82 are connected to the top plate 7. The pressure sensor 83 is connected to the limiting component 5. The temperature and humidity sensor 84 and the vibration sensor 85 are connected to the flywheel energy storage system 10.

[0071] The displacement sensor 81 and tilt sensor 82 are used to measure the displacement change and tilt angle of the top plate 7, respectively.

[0072] The pressure sensor 83 is used to measure the pressure value of the limiting component 5;

[0073] The temperature and humidity sensor 84 and the vibration sensor 85 are used to measure the ambient temperature and humidity of the flywheel energy storage system 10 and the vibration frequency and amplitude of the flywheel energy storage system 10.

[0074] The control unit 9 is used to determine whether the flywheel energy storage system 10 is abnormal based on the ambient temperature, humidity and vibration frequency amplitude, and to repair the flywheel energy storage system 10 in advance according to the abnormal situation. It can also determine the tilt status of the top plate 7 based on displacement changes, tilt angle and pressure value.

[0075] In this embodiment, the control unit 9 can be a microcontroller, PLC, or computer. The sensor mainly converts displacement changes, tilt angles, thermal expansion and contraction, humidity, and vibration frequency and amplitude into electrical signals, such as voltage, current, resistance, and frequency, so that the microcontroller, PLC, or computer can recognize and process them. One end of the sensor is connected to the end of the flywheel energy storage system 10 and is connected to the sensor built into the flywheel energy storage system 10 via a line to receive signals from the device. The other end transmits the electrical signals transmitted by the line to the control unit 9, which then identifies and parses the actual situation. Thermal expansion and contraction can cause equipment deformation. When the humidity of the flywheel system is too high, it is prone to leakage and other emergencies. Mechanical vibration can cause resonance of the foundation soil, which can easily lead to liquefaction and uneven settlement. Therefore, by acquiring the ambient temperature and humidity of the flywheel energy storage system 10 and the vibration frequency and amplitude of the flywheel energy storage system 10, various situations can be warned at the same time, which is safer and more efficient. The pressure value can be used to obtain the pressure on the edge steel plate 51. The larger the tilt angle, the greater the pressure on the edge steel plate 51. Therefore, the tilt angle of the top plate 7 can be judged.

[0076] Example 6:

[0077] A leveling method for a leveling device for a containerized flywheel energy storage system as described in Embodiment 5, the leveling method comprising the following steps:

[0078] Step 1: Place the container on the top plate 7, monitor the various parameters of the top plate 7 according to the monitoring unit 8 to obtain the tilt status of the top plate 7, and control the corresponding lifting component 4 to lift the top plate 7 to level it.

[0079] Step 2: After the top plate 7 is leveled, control the sliding of the limiting component 5 so that the limiting component 5 abuts against the side of the container.

[0080] Step 3: Monitor the parameters of the flywheel energy storage system 10, the parameters of the top plate 7, and the force value of the limit component 5 through the monitoring unit 8. Obtain the tilt status of the top plate 7 through the control unit 9, and control the corresponding lifting component 4 to lift and level the top plate 7.

[0081] The calculation of the tilt state of the top plate 7 by the control unit 9 includes:

[0082] When all parameters of the flywheel energy storage system 10 are normal, and the parameters of the top plate 7 and the force value of the limit component 5 exceed the set value, the tilt status of the top plate 7 is calculated by displacement change, tilt angle and pressure value, and the corresponding lifting component 4 is controlled to lift and level the top plate 7.

[0083] When all parameters of the flywheel energy storage system 10, all parameters of the top plate 7, and the force value of the limit component 5 exceed the set value, the tilt status of the top plate 7 is calculated by displacement change, tilt angle, and pressure value, and the corresponding lifting component 4 is controlled to lift and level the top plate 7. If all parameters of the flywheel energy storage system 10 still exceed the set value, the flywheel energy storage system 10 is repaired.

[0084] When the parameters of the flywheel energy storage system 10 exceed the set values, and the parameters of the top plate 7 and the limit component 5 are normal, the flywheel energy storage system 10 is repaired.

[0085] In this embodiment, the flatness of the bottom plate 3 is set to ≤1 / 1000, the flatness of the top plate 7 is set to ≤0.003 / 1000, and the levelness inside the container is ≤0.5 / 1000. The elevation change of the top plate 7 can be calculated by measuring the displacement change and tilt angle through the displacement sensor 81 and the tilt angle sensor 82. The elevation change can be used to control the corresponding jack 41 to lift to the corresponding height. The tilt angle of the container can be calculated by the pressure value and the weight of the container. When it is lifted to the specified height, the deviation of the top plate 7 is less than the maximum allowable deviation of flatness, and the deviation of the container is less than the maximum allowable deviation of levelness. The leveling of the top plate 7 is then completed.

[0086] Example 7:

[0087] The basic content is the same as Example 2, except that:

[0088] See Figure 3 When the control unit 9 calculates the tilt of the top plate 7 and controls the lifting assembly 4 to lift it, after the top plate 7 is leveled, the winch 15 is placed at the lifting position of the lifting assembly 4, and the grouting groove 13 is dug on the outside of the bottom plate 3. The steel strand 14 of the winch 15 is connected to the bottom plate 3, and the winch 15 is controlled to work to lift the bottom plate 3. The lifting height is the same as the lifting height of the lifting assembly 4. During the lifting process, the liquid storage box 25 is damaged by pressure, and the internal adhesive fills the cavity 24. At the same time, the lifting assembly 4, which has been lifted, is controlled to descend synchronously to keep the top plate 7 horizontal. After the bottom plate 3 is leveled, grout is injected into the grouting groove 13 to fill the gap. After the grout solidifies, the steel strand 14 is removed and the winch 15 is taken out.

[0089] In this embodiment, the grouting trough 13 is connected to the pre-embedded trough 22. After the bottom plate 3 settles, the tilt angle and tilt position of the bottom plate 3 are monitored by the monitoring unit 8. Then, a winch 15 is placed at the corresponding position, the winch 15 is started, the winch 15 pulls the steel strand 14 to adjust the position of the bottom plate 3, and controls the already lifted lifting component 4 to descend synchronously. The changes in the values ​​of the displacement sensor 81 and the pressure sensor 83 are observed in real time to avoid exceeding the set value. When the value of the displacement sensor 81 returns to the initial value, the winch 15 stops pulling the steel strand 14.
