Description

Technical Field

[0001] This invention relates to the field of chemical treatment technology for contaminated soil, and more specifically to a 3D imaging system for chemical treatment of contaminated soil. Background Technology

[0002] The following are some chemical remediation technologies for soil pollution:

[0003] 1. Soil property improvement technology

[0004] The principle of this technology is to transform pollutants into non-migratory, low-activity substances or remove them from the soil. Soil properties can be improved through the application of amendments and by altering the soil's redox potential (Eh). This technology primarily targets heavy metals and is also known as heavy metal passivation, proving highly effective in lightly polluted soils. Soil amendment technology is an in-situ remediation technique that does not require complex on-site engineering equipment, making it an economical and effective remediation method. Generally, for lightly polluted soils, based on the characteristics of pollutants in the soil, amendments such as calcareous substances, organic matter, clay minerals, and ion antagonists can be added to improve soil properties and remediate soil contaminated with heavy metals. The migration behavior of heavy metals in soil is closely related to the soil's redox potential (Eh). Under reducing conditions, many heavy metal elements in soil combine with generated H2S to form insoluble sulfide precipitates with prolonged flooding. Therefore, methods such as flooded cultivation, applying substances that promote reduction in the water, and providing a source of H2S can be used to reduce the activity of heavy metals and mitigate their toxicity. An American company developed the Envirobond™ technology based on laboratory research and implemented it at two lead-contaminated sites in Rosebille, Ohio, achieving a removal rate of over 99%.

[0005] 2. Chemical redox remediation technology and reductive dechlorination technology

[0006] Chemical oxidation remediation is an in-situ soil remediation technology that involves installing brick wells at varying depths in the contaminated area and injecting chemical oxidants into the soil via pumps within the wells. The oxidants react with the pollutants, causing them to degrade or transform into low-toxicity, low-migration products. Commonly used oxidants include H₂O₂, K₂MnO₄, and gaseous Q₃. This type of remediation technology generally consists of three parts: injection wells, extraction wells, and the oxidant. It is primarily used to remediate pollutants that have been contaminated in the soil for a long period and are difficult to biodegrade, such as oils, organic solvents, polycyclic aromatic hydrocarbons (PAHs), PCP, pesticides, and non-water-soluble chlorides (such as trichloroethylene and TCE). Chemical reduction remediation and reductive dechlorination remediation operate on the same principle as chemical oxidation remediation. Representative reducing agents include liquid SO₂, gaseous H₂S, and zero-valent Fe colloids. This type of remediation technology has many successful cases and is both time-saving and economical.

[0007] 3. Chemical rinsing remediation technology

[0008] The chemical rinsing system consists of three parts:

[0009] 1. Equipment for applying leachate to soil;

[0010] II. Lower layer leachate collection system;

[0011] III. Leachate Treatment System. This technology utilizes hydraulic pressure to propel a cleaning solution through contaminated soil, thereby removing contaminants. The cleaning solution containing contaminants is then separated and treated. The cleaning solution can be either chemical reagents or water. This technology has low operating costs, and operators do not directly contact the contaminants. However, it is only suitable for soils with high permeability, such as sandy loam, and the introduced cleaning agents can easily cause secondary pollution. This type of technology has a wide range of applications, including contaminants such as heavy metals, aromatics, petroleum hydrocarbons, halogenated reagents, polychlorinated biphenyls (PCBs), chlorophenols, and pesticides.

[0012] GIS (Geographic Information System) is a discipline that has developed alongside the advancements in geographical science, computer technology, remote sensing technology, and information science. Supported by computer hardware and software systems, it is a technological system for collecting, storing, managing, processing, analyzing, displaying, and describing geographic distribution data across the entire or part of the Earth's surface (including the atmosphere). Currently, in the field of urban (industrial park) planning and management, GIS plays a crucial role as an intuitive and rational planning tool, fulfilling important functions such as data storage, management and analysis, planning scheme presentation and decision-making, and urban (industrial park) management services.

[0013] GIS is mainly used for macro-regional data, including basic geographic data, planning information, above-ground and underground pipeline systems, road systems, population and other information; BIM is mainly used for micro-level individual buildings, covering all disciplines of information such as structure, space, air conditioning, water and heating of individual buildings.

[0014] Given the current development of automation, automated treatment of contaminated land can effectively reduce the impact of environmental pollution on workers. On this basis, by using 3D technology combined with GIS+BIM technology, the entire soil improvement process can be monitored in real time, and the data transmission problems in offline mode can be overcome. Summary of the Invention

[0015] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a 3D imaging system for chemical treatment of contaminated soil.

[0023] In this invention, the shock-absorbing device is located below the main body of the device, and the mounting base plate is fixed to the lower end surface of the shock-absorbing device.

[0024] The main body of the device is provided with connecting columns. The connecting columns are vertically placed cuboids. There are four connecting columns.

The lower end of the connecting column is located below the lower end of the main body of the device.

[0025] Furthermore, in this invention, the offline upload of the BIM+GIS system data collection device is based on offline upload from a local server.

[0026] In this invention, the shock-absorbing device further includes a left shock-absorbing plate, a left shock-absorbing gear, a horizontal longitudinal shaft, a right shock-absorbing plate, a right shock-absorbing gear, and a torsion spring.

[0027] Both the left and right shock-absorbing plates are vertically placed rectangular panels. Both the left and right shock-absorbing plates are provided with horizontal longitudinal gear teeth.

[0038] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] like Figure 3 As shown, a 3D imaging system for chemical treatment of contaminated soil includes a BIM+GIS system data collection device, an offline data upload module, and a data integration module.

[0041] The BIM+GIS system data collection devices are arranged in an array within the contaminated soil area. Each device is cuboid in shape and includes a shock-absorbing device 2, data collection components, and various signal acquisition modules. The data collection device mainly includes modules for collecting movement and dosing information of the remediation equipment 5. It collects relevant movement information data wirelessly via Bluetooth or other methods. When the remediation equipment 5 moves near each BIM+GIS system data collection device, the two actively establish signal communication. Adjacent BIM+GIS system data collection devices also network with each other to share information. Because the remediation equipment 5 vibrates the ground during operation, a shock-absorbing device 2 is installed at its base to prevent the BIM+GIS system data collection devices from tipping over. The structure of the shock-absorbing device 2 is as follows:

[0042] like Figure 2As shown, the vibration damping device 2 includes a left vibration damping plate 2.1, a left vibration damping gear 2.2, a horizontal longitudinal shaft 2.3, a right vibration damping plate 2.4, a right vibration damping gear 2.5, and a torsion spring 2.6. Both the left and right vibration damping plates 2.1 and 2.4 are vertically placed rectangular plates. Both plates have several horizontal longitudinal gear teeth 4, evenly distributed on their side end faces. Several teeth are located on the right end face of the left vibration damping plate 2.1 and on the left end face of the right vibration damping plate 2.4. There are two horizontal longitudinal shafts 2.3, with both ends of the shafts fixedly connected to the lower end of the connecting column 1.1 via bearings. At the end, the left anti-vibration gear 2.2 and the right anti-vibration gear 2.5 are respectively fixedly sleeved on the horizontal longitudinal shaft 2.3. The left anti-vibration gear 2.2 meshes with the horizontal longitudinal gear 4 on the left anti-vibration plate 2.1, and the right anti-vibration gear 2.5 meshes with the horizontal longitudinal gear 4 on the right anti-vibration plate 2.4. The two ends of the two horizontal longitudinal shafts 2.3 are fixedly connected to the connecting column 1.1 by torsion springs 2.6. The mounting base plate 3 is a rectangular plate placed horizontally longitudinally. There are two mounting base plates 3, which are respectively fixed on the lower end faces of the left anti-vibration plate 2.1 and the right anti-vibration plate 2.4. The mounting base plate 3 is provided with mounting holes. The torsion spring 2.6 is sleeved on the horizontal longitudinal shaft 2.3. One end of the torsion spring 2.6 is fixed on the horizontal longitudinal shaft 2.3, and the other end of the torsion spring 2.6 is fixed on the connecting column 1.1.

[0043] When the treatment equipment 5 approaches the BIM+GIS system data collection device, the vibration wave generated by its movement is a lateral wave that exerts an upward compressive force on the ground soil. When subjected to this upward vibration force, the left anti-vibration plate 2.1 and the right anti-vibration plate 2.4 move upward. At this time, the left anti-vibration gear 2.2 and the right anti-vibration gear 2.5 will rotate. In this way, the main body 1 of the device will not be subjected to the upward force of the left anti-vibration plate 1 and the right anti-vibration plate 2.4. However, due to the action of the torsion spring 2.6, the left anti-vibration gear 2.2 and the right anti-vibration gear 2.5 will move in the opposite direction after being subjected to the vibration force. That is, the function of the torsion spring 2.6 is to restore the anti-vibration gear 2.2 and the right anti-vibration gear 2.5 to their original state. This prevents the vibration force received by the left anti-vibration plate 2.1 and the right anti-vibration plate 2.4 from affecting the main body 1 of the device.

[0044] 2) Offline data upload:

[0045] The BIM system within the BIM+GIS system data collection device collects sensor-transmitted data and supervisory inspection data in real time offline, and synchronizes the collected data to a shared database via a synchronization tool. The GIS system within the BIM+GIS system data collection device collects and stores basic geographic data (collected manually), planning information (collected manually), governance equipment information (shared with the equipment's data transmission module), and weather information (including temperature, light, and humidity sensors), and synchronizes the data to a shared database via a synchronization tool. The offline upload of the BIM+GIS system data collection device is based on offline upload from a local server.

[0046] 3) Data integration:

[0047] The server parses and applies the data in the database.

[0048] Offline Data Collection for GIS: To achieve offline data collection, the contents of the spatial data repository or its sub-repository must first be encrypted and imported into the mobile terminal using a synchronization tool. Due to the large volume of enterprise-level offline data collection, this method selects the embedded database Spatialite to store offline business data. On the mobile terminal, we use ArcGIS runtime for Android / iOS and the extended Spatialite API to read and manipulate (create, delete, modify, and query) the offline data packets, completing the mobile data collection function. Finally, we use a data synchronization tool to synchronize the collected data to the ArcGIS data repository or its sub-repository.

[0049] The BIM+GIS system data collection device also includes a small battery module, a data storage hard drive, and several circuit boards.

[0050] In the remote server 6 in the office, in an offline state, the received data is restored and a 3D graphic is constructed to restore the current operating status of the treatment device 5 in real time, and at the same time obtain various information inside the treatment device 5, such as the amount of pesticides added and the amount of pesticides remaining.

[0051] This interface also displays data such as the actual scope of the governance effort. If other devices are also involved in the collaborative governance, their information will also be displayed simultaneously.

[0052] In offline mode, staff can reconstruct the operation process and problems encountered by the treatment equipment 5 from the information stored inside the main unit 1. This allows them to review which areas have been treated offline and what problems occurred in those areas. This greatly facilitates the treatment of contaminated soil and significantly reduces the amount of protective clothing needed, thus effectively protecting the personal safety of staff.

[0053] In this solution, the data transmission is carried out using various commonly used sensor block data modules, such as Bluetooth modules, 4G wireless network modules, and weather information collection modules.

[0054] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and other solutions employed. Furthermore, the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
