Description

Technical Field

[0001] The present invention relates to the field of contaminated site remediation engineering, and in particular to an intelligent earthwork allocation method and management system for contaminated sites. Background Art

[0002] The process of soil pollution control and remediation for construction land is usually carried out by means of on-site, off-site or external disposal, involving the excavation, on-site transportation, temporary storage and off-site transportation of contaminated soil and clean soil. The allocation of contaminated soil is significantly different from general earthwork allocation projects, mainly manifested in: (1) All contaminated soil must be excavated and transported cleanly, and no contaminated soil can be left at the bottom and side walls of the foundation pit. The total earthwork volume of excavation, temporary storage and external transportation must be consistent; (2) Soil excavation at contaminated sites involves the excavation, temporary storage and transportation of soil from different areas, depths and types of pollutants. The allocation process of different contaminated soils requires the avoidance of cross-contamination; (3) There are generally sensitive areas such as residential areas around contaminated sites. The risk of secondary pollution such as dust from contaminated soil and (semi-) volatile organic pollutants in the air is high and of high concern, and safety risk prevention and control management measures for surrounding people and workers are required. Higher requirements; (4) The contaminated areas at each layer are generally irregular, and may contain underground pipelines, ground cultural relics and ancient trees. Soil excavation is mostly guided by traditional drawings and relies heavily on the experience of on-site construction personnel, project managers and supervisors. The degree of precise excavation and management is insufficient, and the construction period is often delayed; (5) The above process requires environmental supervision and supervision, but environmental supervision personnel cannot always be on site and it is difficult to ensure the whereabouts of all contaminated soil; (6) After the restoration project is completed, the excavation of the foundation pit is difficult to match the earthwork allocation process in the construction and development process. There are problems such as repeated construction and repeated construction in the later construction projects, resulting in waste of resources.

[0003] For the earthwork allocation of general construction projects, there are relatively complete intelligent allocation methods, but they cannot meet the needs of the above-mentioned allocation of contaminated soil and clean soil in polluted plots. For example:

[0004] (1) CN107392348A (Method for optimizing earthwork allocation scheme using BIM technology) uses professional equipment to collect initial terrain data, and generates an electronic initial terrain map based on the BIM real-scene modeling tool. Then, the BIM tool dedicated to infrastructure design is used to calculate the design elevation to form an electronic design terrain map. The excavation area and the filling area are determined by the intersection line and the relative position relationship between the two. Then, the unit freight is determined by calculating the straight-line distance between the centers of gravity of each sub-area. Then, the earthwork allocation scheme with the minimum freight is calculated through BIM software and used as the optimal allocation scheme. The data collection is accurate, the data processing speed is increased by dozens of times, and the calculation accuracy can be adjusted according to the needs of the project, which can fully meet the requirements of modern construction. However, this method only uses transportation cost as the main factor to form the optimal allocation scheme for general earthwork, does not prevent the risk of cross-contamination of different polluted soils, and does not link with secondary pollution prevention and control measures such as air and noise.

[0005] (2) CN109034499A (Airport Earthwork Balance Allocation Optimization Method) discloses an airport earthwork balance allocation optimization method, including the following steps: draw a boundary line between the excavation area W and the filling area T on a plan view, and draw a number of allocation areas in the excavation area W and the filling area T respectively; calculate the earthwork volume of each allocation area in the excavation area W and the filling area T respectively, and mark them on the plan view; calculate the average transportation distance from each allocation area in the excavation area W to each allocation area in the filling area T; determine the allocation plan, including: determine the initial plan by using the nearest allocation method; check the initial plan by using the potential method or the matrix method to determine whether the total earthwork transportation volume is the minimum value, if it is determined that the total earthwork transportation volume is the minimum value, directly draw the earthwork allocation diagram, if the total earthwork transportation volume is not the minimum value, use the closed loop method to adjust until the total earthwork transportation volume is the minimum value. The present invention minimizes or reduces the total earthwork transportation volume to a minimum while shortening the construction period, thereby reducing costs. However, this method is unable to track and deploy on-site equipment routes and soil movements in real time, does not take into account secondary pollution prevention, and does not consider the protection of ancient trees and historical buildings.

[0006] (3) CN107392348A (Method for optimizing earthwork allocation plan using BIM technology) also only considers the optimal earthwork allocation plan based on transportation costs. It does not have measures to prevent the risk of cross-contamination of different contaminated soils, nor does it have secondary pollution prevention and control measures.

[0007] (4) CN117216936A (A method for visually allocating earth and rock based on multi-source data twins of unmanned aerial vehicles) realizes the intelligent analysis and visual simulation of the calculation of engineering earth and rock volume and its allocation method, improves the informationization and automation level of earth and rock calculation and allocation, reduces the cost of engineering filling and excavation, and realizes the intelligent management and control of earth and rock allocation. However, it does not consider the tracking of different contaminated soils and different equipment during the implementation process, nor does it consider the prevention of cross-contamination risks.

[0008] (5) CN117494264A (A method and system for earthwork allocation based on integration of BIM and GIS) provides a method and system for earthwork allocation based on integration of BIM and GIS. The GIS model is established by obtaining images of the project site through topographic survey, and the BIM model is established through construction drawings. The two models are integrated, and soil that does not meet the construction requirements is added to the earthwork volume calculation of the earthwork allocation plan. The accurate calculation of the earthwork volume saves construction costs and speeds up construction. However, the real-time movement of contaminated soil in the process is unclear, there are no measures to prevent the risk of cross-contamination of different contaminated soils, and there are no secondary pollution prevention measures.

[0009] It can be seen that there is no solution to the above-mentioned soil allocation of contaminated plots. In view of the shortcomings of the existing technology, the present invention provides an intelligent soil allocation method and management system for contaminated sites. By combining GIS technology, smart equipment, online monitoring and visualization equipment, etc., while deciding the optimal on-site and off-site transportation routes, it can achieve accurate positioning and real-time supervision of contaminated soil, effectively prevent secondary pollution, and protect the health of surrounding sensitive people and occupational groups.

[0053] Figure 1 This is the intelligent allocation method of earthwork in a contaminated site according to an embodiment of the present invention;

[0054] Figure 2 This is a diagram of the earthwork coordination and allocation system according to an embodiment of the present invention. DETAILED DESCRIPTION

[0055] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only embodiments of a part of the present invention, rather than all embodiments.

[0056] The embodiment of the present invention discloses a method for intelligently allocating earthwork in a contaminated site. Figure 1 As shown, including:

[0057] Acquire contaminated site information, determine an excavation area and a temporary storage area, the excavation area at least includes a first contaminated type soil area and a first clean soil area, and the temporary storage area at least includes a first contaminated type soil temporary storage area and a first clean soil temporary storage area;

[0058] Among them, the contaminated site information at least includes the contamination situation of the contaminated site. The method of the embodiment of the present invention can classify the contaminated site by region according to the actual contamination situation to form one or more contaminated type soil areas and clean soil areas; and analyze the environment of the temporary storage area to obtain the clean area in the temporary storage area (i.e., the first clean soil temporary storage area) for storing the clean soil after excavation; obtain the area in the temporary storage area that can store contaminated soil (i.e., the first contaminated type soil temporary storage area) for storing the contaminated soil after excavation. In actual scenarios, if the temporary storage area is clean soil, a polymer protective layer can be laid on the surface of the clean soil as a protective layer to prevent the contaminated soil from polluting the clean soil in the temporary storage area during placement;

[0059] Determine an earthwork transportation route based on the location information of the excavation area and the temporary storage area, wherein the first contaminated type soil area and the first contaminated type soil temporary storage area are provided with at least a first earthwork transportation route, and the first clean soil area and the first clean soil temporary storage area are provided with at least a second earthwork transportation route, and the first earthwork transportation route and the second earthwork transportation route are different;

[0060] Among them, the first earthwork transportation route and the second earthwork transportation route can be set as the shortest routes as much as possible. If conditions do not permit, the first earthwork transportation route shall be set as the shortest route, and the second earthwork transportation route can be set up as a detour to avoid large-scale overlap between the first earthwork transportation route and the second earthwork transportation route, so as to reduce the contamination of clean soil by contaminated soil.

[0061] The embodiments of the present invention effectively distinguish between polluted soil and clean soil, and plan different transportation routes, which can effectively prevent cross-contamination, realize intelligent route design and execution, reduce project time consumption, reduce supervision costs, improve supervision timeliness, and realize real-time linkage supervision. After the repair project is completed, the excavation of the foundation pit is matched with the earthwork allocation process of the construction and development process, reducing duplicate construction and duplicate construction.

[0062] Optionally, obtaining the contaminated site information and determining the excavation area and temporary storage area includes:

[0063] Obtain information on contaminated sites and identify underground conditions and soil contamination at contaminated sites;

[0064] Among them, the actual environmental information of the contaminated site can be collected, including the underground pipeline settings, pollution conditions, ground height, etc. of the contaminated site;

[0065] Determine an excavation area and a temporary storage area, wherein the temporary storage area is used to temporarily store excavated earth;

[0066] Among them, based on the actual environmental information of the contaminated site, the excavation area is classified into pollution levels, and areas with similar pollution levels can be classified as areas of the same pollution type soil;

[0067] Set up car wash areas, maintenance areas and parking areas for transport vehicles.

[0068] Among them, outside the excavation area and temporary storage area, the transport vehicle washing area, maintenance area and parking area are set up. In addition, the transport vehicle washing area, maintenance area and parking area are at least classified into pollution type and clean type. The locations of the pollution type transport vehicle washing area, maintenance area and parking area are different from those of the clean type transport vehicle washing area, maintenance area and parking area to realize the division of pollution areas and clean areas.

[0069] By collecting information on contaminated sites, the embodiments of the present invention can identify the underground conditions and soil pollution conditions of the contaminated sites, make accurate divisions based on the actual pollution conditions of the sites, achieve effective isolation of contaminated areas and clean areas, and avoid cross-contamination of the soil during the construction process.

[0070] In particular, the obtaining of polluted site information and determining the excavation area and temporary storage area also includes:

[0071] Obtain geographic information of sensitive areas around contaminated sites;

[0072] Among them, sensitive areas are specifically residential areas, schools, hospitals, farmlands and other areas where people live and where food is sourced outside the polluted area. Specific geographical information on the type of pollution and depth of pollution in the polluted soil area can be confirmed;

[0073] Based on geographic information, the atmospheric conditions in sensitive areas are determined. Based on the atmospheric conditions, air quality monitoring sites and noise monitoring sites are set up to obtain atmospheric dust and noise conditions.

[0074] Among them, the atmospheric conditions of the sensitive area are obtained, and based on the atmospheric conditions, the upwind and downwind areas are determined. Air quality monitoring sites are set up in the downwind area to determine the dust conditions in the sensitive area. Noise monitoring sites are set up around the sensitive area to achieve noise monitoring.

[0075] The embodiments of the present invention can effectively monitor the air pollution situation in sensitive areas by determining the atmospheric conditions in sensitive areas, thereby achieving effective monitoring, reducing the risk of air pollution, and reducing the pollution of polluted sites to surrounding sensitive areas.

[0076] In particular, an embodiment of the present invention also includes that, if a target area outside the contaminated site is also included, the current contaminated site location is used as the starting point, the target area is used as the end point, and the sensitive area is set as an avoidance point to obtain a transportation route, and the transportation route at least does not overlap with the roads around the sensitive area; if the transportation route cannot avoid the sensitive area, the route with the smallest overlap area with the roads around the sensitive area is used as the transportation route.

[0077] Among them, the target areas outside the contaminated site also include treatment areas such as cement kilns and centralized disposal centers for centralized treatment of contaminated soil. In traditional route planning, there is a lack of solutions for route avoidance based on sensitive areas. The embodiments of the present invention reasonably set routes based on the locations of sensitive areas to avoid pollution of sensitive areas.

[0078] Optionally, determining the earthwork transportation route based on the location information of the excavation area and the temporary storage area includes:

[0079] Determine a first contaminated soil area and a first clean soil area in the excavation area, and determine that the temporary storage area at least includes a first contaminated soil temporary storage area and a first clean soil temporary storage area;

[0080] Among them, for complex contaminated sites involving multiple pollution types, multiple soil areas of different pollution types such as the first pollution type soil area and the second pollution type soil area can be set according to different pollution types. For example, the first pollution type soil area is mainly organic pollution area, and the second pollution type soil area is mainly inorganic heavy metal pollution soil. By classifying the polluted soil in detail, cross-contamination of soils of different pollution types during the construction process can be effectively avoided;

[0081] Taking the first pollution type soil area and the first pollution type soil temporary storage area as two points, a first earthwork transportation route is set;

[0082] Among them, the first pollution type soil area and the first pollution type soil temporary storage area are taken as two points, and the shortest route is planned according to the characteristics of the pollution site to form the first earthwork transportation route;

[0083] A second earthwork transportation route is set up with the first clean soil area and the first clean soil temporary storage area as two points;

[0084] Among them, the first clean soil area and the first clean soil temporary storage area are taken as two points, and an avoidance design is performed based on the first earthwork transportation route to form a second earthwork transportation route, and the first earthwork transportation route and the second earthwork transportation route are adjusted to minimize the overlapping area of ​​the first earthwork transportation route and the second earthwork transportation route.

[0085] Another aspect of the present invention is to disclose an intelligent management system for soil and rock allocation in a contaminated site. Figure 2 As shown, including:

[0086] An execution layer, the execution layer is used to obtain instruction information of an execution person;

[0087] The execution layer is functional software integrated into computers, smart tablets, mobile phones, etc., which can realize the setting of related execution layer functions; in addition, the execution layer also includes GIS positioning module, monitoring and analysis module, etc. All users involved in the design and transportation process are execution layer users;

[0088] The decision layer is used to obtain the information collected by the execution layer and feedback decision information based on preset conditions;

[0089] Among them, the decision-making layer is a functional software integrated into computers, smart tablets, mobile phones, etc., which can realize the setting of relevant decision-making layer functions; the functions of the decision-making layer are mainly to review the key nodes of the execution layer, supervise the earthwork allocation process, provide the supervision layer with materials such as the letter of intent to receive the off-site disposal unit and hazardous waste identification documents, open and close the user rights of the execution layer, open the user rights of the supervision layer, and the management level of the project operation and the project supervision, environmental supervision, effect evaluation personnel, etc. are all decision-making layer users;

[0090] The supervisory layer is used to obtain instruction information from the executors and to give a prompt when the instruction information does not meet the preset conditions;

[0091] Among them, after the supervision layer users are connected to the management system of a specific plot of land by the management layer, they can view various real-time data of the execution layer in real time, and send various inspection documents, supervision policy documents, complaints and inspection results, extreme weather or geological disaster warning forecasts, etc. to the management layer in the process. Only the supervision layer users have the authority to close the supervision layer users of the local plot.

[0092] The intelligent allocation and management system for earthwork in polluted sites also includes:

[0093] Obtain the contaminated site information input by the execution layer and determine the excavation area and temporary storage area;

[0094] The decision-making layer determines the earthwork transportation route based on the location information of the excavation area and the temporary storage area;

[0095] The excavation area includes at least a first contaminated soil area and a first clean soil area, the temporary storage area includes at least a first contaminated soil temporary storage area and a first clean soil temporary storage area, the first contaminated soil area and the first contaminated soil temporary storage area are provided with at least a first earthwork transportation route, the first clean soil area and the first clean soil temporary storage area are provided with at least a second earthwork transportation route, and the first earthwork transportation route and the second earthwork transportation route are different.

[0096] The execution layer of the embodiment of the present invention can effectively distinguish between polluted soil and clean soil, and the decision layer can plan different transportation routes, which can effectively prevent cross-contamination, realize intelligent route design and execution, reduce engineering time consumption, reduce supervision costs, improve supervision timeliness, and realize real-time linkage supervision. After the repair project is completed, the excavation of the foundation pit is matched with the earthwork allocation process of the construction and development process, reducing repeated construction and repeated construction. In addition, the embodiment of the present invention realizes the monitoring and collection of relevant information of the execution layer and the decision layer by setting up the supervision layer.

[0097] Optionally, the obtaining of the contaminated site information input by the execution layer and determining the excavation area and the temporary storage area includes:

[0098] The execution layer obtains the boundary coordinates and elevation information of the plot input by the user in the GIS-based positioning module and sets the vehicle entrance and exit of the site;

[0099] Among them, the user of the execution layer can input the specific information of the contaminated site, including boundary coordinates and elevation information, into the device installed with the execution layer software. The execution layer software can automatically set the entrance and exit of the site vehicle based on the specific information of the contaminated site. It should be noted that the site vehicle entrance and exit is specifically the site entrance and exit during the construction process, which is used to realize the normal entry and exit of construction equipment such as excavators and bucket trucks. The site vehicle entrance and exit is preferably in the clean soil area to prevent vehicles from taking contaminated soil out of the contaminated site;

[0100] Based on the coordinates provided by the site soil contamination status survey and risk assessment report, the surface excavation range and elevation were determined using RTK equipment, and the lines were laid out on site;

[0101] Among them, the execution layer equipment can determine the surface excavation range and elevation based on the coordinates provided by the site soil pollution status survey and risk assessment report, combined with the RTK equipment, and lay out the lines on site to obtain excavation-related information;

[0102] Using BIM technology, a site boundary model is constructed based on the GIS positioning module, including information on buildings and trees to be bypassed, and a three-dimensional map of the excavation range of different contaminated soils is established;

[0103] Among them, using BIM technology, a site boundary model is constructed in the GIS positioning module based on the execution layer equipment, including the information of the buildings and trees to be bypassed, to establish a three-dimensional map of the excavation range of different contaminated soils; and based on historical data and ground penetrating radar and other means, it is identified whether there are pipelines and underground devices within the excavation range and added to the three-dimensional map;

[0104] Areas with different contaminated soils are marked separately, and the planned volume of each type of contaminated soil and clean soil to be excavated is recorded in the system, and the volume of suspected contaminated soil at the edge of the excavation area is estimated.

[0105] Among them, information such as areas of different contaminated soils and excavation volumes are marked in the three-dimensional map.

[0106] Based on the above method, the embodiment of the present invention can establish a three-dimensional map and information such as the areas of different contaminated soils and the amount of excavation based on the execution layer device, and can form an easily recognizable three-dimensional map to facilitate system users to perform corresponding queries.

[0107] Optional, such as Figure 2 As shown, the decision layer determines the earthwork transportation route based on the location information of the excavation area and the temporary storage area, and also includes:

[0108] Establishing a visualization model, dividing the excavation area, the temporary storage area, and the earthwork transportation route into at least one contaminated soil area and at least one clean soil area;

[0109] Among them, based on the three-dimensional map, a visualization model is established to facilitate personnel viewing, and the location information of the excavation area and the temporary storage area, and the earthwork transportation route are displayed on the visualization model, and the same type of contaminated soil areas, clean soil areas, and earthwork transportation routes are unified into a contaminated soil area (for example, the first contaminated type soil area, the first contaminated type soil temporary storage area, and the first earthwork transportation route are formed into a first contaminated soil area, and the first clean soil area, the first clean soil temporary storage area, and the second earthwork transportation route are formed into a clean soil area);

[0110] Working equipment is allocated to different areas, and the working equipment includes an excavator and a bucket truck. The contaminated soil area and the clean soil area do not share the same working equipment.

[0111] Among them, when conditions permit, each contaminated soil area can be equipped with a separate excavator and bucket truck to achieve "special area for special purpose". When conditions do not permit, at least ensure that the excavators and bucket trucks in the contaminated soil area are different from those in the clean soil area to avoid contamination of the contaminated soil to the clean soil. In subsequent work, the GPS positions of the excavators and bucket trucks can be continuously tracked. When the excavators and bucket trucks enter other soil areas (excavators and bucket trucks in the contaminated soil area enter the clean soil area or excavators and bucket trucks in the clean soil area enter the contaminated soil area), tracking and alarming can be carried out to avoid soil contamination and realize remote intelligent management and control.

[0112] In particular, the excavator and bucket truck are equipped with GPS equipment;

[0113] Among them, the GPS equipment on the excavator and bucket truck can locate the position of the excavator and bucket truck in real time.

[0114] The intelligent deployment management system for earthwork in contaminated sites also includes a working equipment route monitoring process:

[0115] Determine the operation route in response to the current status of the working equipment;

[0116] The working equipment specifically refers to excavators and bucket trucks. If the working equipment is currently in working state, its operation route is limited to the corresponding soil area. If the working equipment is currently in non-working state such as maintenance or cleaning, the driver sends a request to the decision-making layer, and after approval, the decision-making layer resets the route based on its current position and target positions such as the transport vehicle washing area, maintenance area, and parking area.

[0117] If the route of the working equipment does not match the operating route, a prompt is sent to the execution layer and / or the management layer.

[0118] Among them, if the working equipment is not approved by the decision-making level and the route it travels does not match the operating route, the system will issue a prompt to the execution-level user and the management-level user when the GPS signal of the working equipment deviates from the operating route.

[0119] The method of the embodiment of the present invention can perform real-time GPS tracking management on the working equipment, realize real-time control of the working equipment, and prevent the working equipment from entering other soil areas due to the driver's own decision and causing pollution.

[0120] In particular, the intelligent deployment management system for earthwork at contaminated sites also includes a work equipment task setting process:

[0121] Sending task information to the working equipment, wherein the task information includes at least position coordinate instructions, excavation depth, excavation amount, and operation time;

[0122] The working equipment itself can also be equipped with a vehicle-mounted terminal, and the execution layer software can be integrated on the vehicle-mounted terminal. When the operation starts, the system issues a position coordinate instruction, and the driver drives to the corresponding coordinate and excavates to the specified depth. The vehicle-mounted terminal tracks and records the excavation position, excavation volume and operation time of the corresponding batch of contaminated soil in real time.

[0123] Obtain the operation process of the working equipment and determine the real-time unloading position, unloading amount and operation time of the working equipment;

[0124] Among them, the corresponding batch of contaminated soil is unloaded after reaching the designated coordinate range, and the vehicle terminal automatically records the unloading location, unloading amount and operation time in real time;

[0125] The system displays data in the visual model in real time to show the current excavation and adjustment quantities.

[0126] Among them, after the operation is completed, the system will mark the transferred earthwork at the corresponding coordinates in real time and continue to issue transfer instructions until the excavation and allocation of the area is completed. The system will automatically display the excavation and allocation quantities.

[0127] The embodiment of the present invention can realize automatic distribution and monitoring of work equipment tasks through the work equipment task setting process.

[0128] In particular, the obtaining of polluted site information and determining the excavation area and temporary storage area also includes:

[0129] Obtain geographic information of sensitive areas around contaminated sites;

[0130] Among them, sensitive areas are specifically residential areas, schools, hospitals, farmlands and other areas where people live and where food is sourced outside the polluted area. Specific geographical information on the type of pollution and depth of pollution in the polluted soil area can be confirmed;

[0131] Based on geographic information, the atmospheric conditions in sensitive areas are determined. Based on the atmospheric conditions, air quality monitoring sites and noise monitoring sites are set up to obtain atmospheric dust and noise conditions.

[0132] Among them, in accordance with the requirements of secondary pollution prevention and control, online air quality monitoring equipment and noise monitoring equipment are installed near sensitive areas and in the upwind and downwind areas of the mainstream wind at the boundaries of the restoration site. The real-time monitoring data can be transmitted to the monitoring module for storage and analysis. The monitoring module sets the standard threshold for atmospheric dust and the standard threshold for noise in different time periods. Once the index exceeds the threshold standard, a prompt will be issued to the decision-making level.

[0133] During the working process, if the online detection of atmosphere or noise shows that the index exceeds the corresponding standard, a prompt will be issued to the working equipment, the operator will suspend the operation, and a warning message will be sent to the decision-making level, and the decision-making level users will conduct self-inspection. All data are fed back to the user end of the supervision level in real time. If the equipment is not approved to leave the established route, the atmosphere or noise index exceeds the standard, etc., a prompt window will pop up in time.

[0134] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that after reading the specification of this application, the technicians can still modify or replace the specific implementation mode of the present invention with equivalents, but these modifications or changes do not deviate from the scope of protection of the pending claims of the present application.
