Description

Technical Field

[0001] This application relates to the field of soil utilization technology, specifically a soil stripping and reuse system and method. Background Technology

[0002] Soil stripping and reuse technology achieves farmland quality protection and ecological restoration by stripping, storing, and reusing high-quality topsoil occupied by construction. In existing technologies, soil stripping and reuse is typically based on a static design model. Before construction, the static stripping volume is determined using pre-set excavation zone parameters (such as area and depth), and the static storage volume is determined based on the fixed capacity of the storage zone (such as design height and area). Finally, a simple quantity balance formula is used to achieve a preliminary match between the excavation and storage zones. However, such systems have significant drawbacks:

[0003] Insufficient consideration of dynamic factors: During the stripping process, dynamic parameters such as changes in terrain slope (e.g., steep slopes reduce the effective stripping area) and actual losses during transportation (e.g., soil spillage caused by vehicle bumps) were not effectively included in the calculation, resulting in a discrepancy between the static stripping volume and the actual usable earthwork volume.

[0004] The storage area is poorly planned: the storage area capacity is designed based only on fixed stacking height and area, without real-time monitoring of the impact of slope changes on stacking safety (such as the risk of collapse caused by excessively steep slopes), and without dynamically adjusting the allowable stacking height according to the actual terrain, resulting in wasted storage capacity or safety hazards.

[0005] The balancing mechanism is too simple: it relies solely on the quantity balance under static conditions (such as the design value of storage volume ≥ stripping volume), and lacks dynamic response to losses during transportation and the real-time status of the storage area (such as slope stability), resulting in low efficiency of earthwork allocation and easy resource shortages or idleness.

[0006] Chinese invention patent CN113439497B discloses a method for stripping and reusing topsoil in hilly and mountainous construction land, and Chinese invention patent CN103918374 discloses a method for stripping and reusing surface soil in hilly and mountainous residential construction land. The core problem is the disconnect between the static design model and the dynamic construction scenario, which makes it impossible to accurately cope with actual engineering variables such as terrain changes, transportation losses, and storage safety, resulting in low soil resource utilization efficiency and high safety risks.

[0007] In summary, a new technical solution for soil stripping and reuse is urgently needed. Summary of the Invention

[0046] Figure 2 This is a flowchart illustrating the soil stripping and reuse method provided in an embodiment of this application. Detailed Implementation

[0047] The technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0048] In this document, the term "comprising" is intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0049] The stripping and utilization of topsoil from paddy fields and other high-quality arable land occupied by construction is a clear provision of the Land Administration Law and the Land Reclamation Regulations, and is a measure to protect high-quality soil resources and deepen arable land protection. In actual construction, it is generally carried out based on the following steps: 1. Determine the project area, current land use status, and arable land quality grade; 2. Conduct on-site soil surveys, analyze the type and degree of soil pollution, and propose improvement and prevention measures; 3. Determine key indicators such as the soil stripping range, soil stripping thickness, and earthwork volume; 4. Determine the soil utilization direction, storage area location, and transportation route; 5. Determine the soil stripping project costs and funding methods; 6. Determine the stripping and utilization guarantee measures; 7. Project benefit analysis. This embodiment optimizes and innovates steps 3, 4, and 6; the implementation methods for other steps can be any of the existing technologies.

[0050] The first aspect of this embodiment discloses as follows: Figure 1The soil stripping and reuse system shown in this paper analyzes the soil quality of the excavation area before stripping the soil, and reuses the soil based on the results of the soil quality analysis. The reused soil is then centrally stockpiled before its intended use is determined.

[0051] The system includes a stripping determination module, a storage determination module, and an earthwork balance module;

[0052] The stripping determination module is configured as follows: the excavation area is determined based on the results of soil quality analysis; the static stripping volume is determined based on the excavation area; and the dynamic stripping volume is determined based on the results of soil transport process analysis after stripping. This dynamic stripping volume is used to characterize the actual effective volume of earthwork.

[0053] The storage determination module is configured to: determine the static storage volume of earthwork based on a preset storage area; and determine the dynamic storage volume of earthwork based on the monitoring status of the storage area.

[0054] The earthwork balance module is configured as follows: static balance is performed based on the amount of stripped earth and the amount of stored earth. This static balance is used to characterize the quantitative balance relationship between the excavation area and the storage area under static conditions; dynamic balance is performed based on the amount of dynamically stripped earth and the amount of dynamically stored earth. This dynamic balance is used to characterize the quantitative balance relationship between the excavation area and the storage area under dynamic conditions. This dynamic relationship is determined by the soil transportation process after stripping and the monitoring of the storage area.

[0055] In a specific application of this embodiment, in a temporary land use project for a highway, the system first determines the excavation areas A (topsoil thickness ≥ 30cm) and B (thickness 20-30cm) through soil quality analysis, and calculates the static stripping earthwork volume as 150m³. 3 and 100m 3 Storage areas C and D each have a preset static capacity of 200m³. 3 During construction, transportation losses were monitored in real time using onboard weighing sensors (loss rate 6% from area A to area C, loss rate 8% from area B to area D). Combined with slope inclination sensor data for area C (slope increased from the initial 15° to 22°), the stripping amount was dynamically adjusted (actual effective stripping amount for area A was 141m³). 3 ) and storage capacity (the allowable stacking height in Zone C is reduced from 2m to 1.8m, and the capacity is adjusted to 180m³). 3 Ultimately, the earthwork balancing module generates allocation instructions based on dynamic data, transferring the excess 12m³ of earthwork in Zone B. 3 The excavated soil was moved to backup area E. It should be noted that the soil quality analysis in this embodiment is based on any existing soil quality analysis method, such as sending soil samples to a corresponding laboratory for testing and analysis.

[0056] Through the above, the coordinated operation of the three modules of stripping, storage, and balancing enables dynamic monitoring of the entire process from soil stripping to storage, reduces the error of earthwork allocation in traditional static design, and reduces the risk of collapse through real-time slope monitoring, significantly improving the efficiency and safety of soil reuse.

[0057] Specifically, the determination of the dynamic stripping earthwork volume includes:

[0058] Obtain the topographic slope data of the excavation area, and correct the static stripping volume based on the topographic slope data to obtain the first corrected stripping volume;

[0059] The load data of the transport vehicle is monitored in real time by the vehicle-mounted weighing sensor. The transport loss rate is calculated based on the load data. The first correction stripping volume is then adjusted based on the transport loss rate to obtain the dynamic stripping volume.

[0060] In the specific application of this embodiment, during the stripping process in excavation area A (with a terrain slope of 18°), data is acquired using existing scanning technology, and calculated according to the formula: Effective stripping area = Original design area (100m²) 2 The effective area is calculated as 64m² by multiplying (1 - 18° / 30°). 2 Revise the static stripping earthwork volume (original design 150m). 3 → Corrected version 96m 3 During the transportation phase, the onboard weighing sensors recorded data for 10 trips, calculating the single-trip loss rate (e.g., for the first trip: (5t-4.7t) / 5t = 6%). The daily weighted average loss rate was 7.2%, further correcting the effective earthwork volume to 89m³. 3 (96m 3 ×(1-7.2%)).

[0061] By using the above methods, the accuracy of dynamic stripping earthwork volume calculation is improved through dual correction of terrain slope and transportation loss, thus avoiding insufficient storage capacity or allocation delays caused by overestimating the stripping volume.

[0062] Specifically, the static stripping earthwork volume is corrected based on terrain slope data, including:

[0063] When the terrain slope corresponding to the terrain slope data is greater than the preset slope threshold, the effective stripping area is calculated. The effective stripping area is determined by the original design area corresponding to the excavation area and the preset slope influence coefficient.

[0064] The static stripping volume is adjusted based on the effective stripping area.

[0065] In the specific application of this embodiment, when excavation area B (whose original design area is 80m²) 2 The static earthwork volume is 100m³. 3When the terrain slope monitoring shows 22° (> slope threshold 15°), the effective stripping area is calculated using the formula: 80m² 2 ×(1-22° / 30° (i.e., the slope influence coefficient))≈21.3m 2 The corrected static earthwork volume is 26.6 m³. 3 (original 100m) 3 ×21.3%. After correction for transportation losses (weighted average loss rate of 8%), the dynamic stripping volume is 24.5 m³. 3 It is 75.5m shorter than the original design. 3 The system adjusts transportation plans accordingly, reducing unnecessary vehicle dispatching and thus saving transportation costs.

[0066] Based on the above, slope correction enables accurate identification of the effective stripping area in steep slope regions, avoiding the resource waste caused by traditional static calculations and achieving cost control.

[0067] Specifically, the transportation loss rate is calculated based on load data, including:

[0068] Calculate the single transport loss rate, which is determined by the stripping load of the transport vehicle at the start of transport and the arrival load at the storage area;

[0069] The weighted average loss rate is obtained based on time series statistics; and when the loss rate of a single continuously monitored event exceeds the preset loss threshold, an anomaly warning is triggered.

[0070] In the specific application of this embodiment, during the transportation process from area A to area C, the system continuously monitors data for 15 trips, calculating the single-trip loss rate fluctuation range as 5%-12%. Through time-series weighted averaging (weights determined based on transportation volume), the daily average loss rate is calculated to be 7.5%. When the loss rate for trips 16-18 consistently exceeds 7.5%, the system triggers an anomaly warning. Based on this warning, an investigation reveals that potholes in a certain section of the transportation route exacerbate the bumpy ride. Timely repairs reduce the loss rate.

[0071] Through the above, the dynamic loss rate calculation and anomaly early warning mechanism realizes real-time monitoring of the transportation process, enables early detection of route problems, optimizes the average loss rate of the transportation process, and reduces soil loss.

[0072] Specifically, the determination of the dynamic storage volume of earthwork includes:

[0073] Real-time monitoring of slope data in the storage area based on tilt sensors;

[0074] The dynamic earthwork volume is obtained by dynamically adjusting the static earthwork volume based on slope gradient data. The dynamic adjustment includes:

[0075] When the difference between the slope gradient and the preset safety threshold is less than or equal to the preset difference threshold, the allowable stacking height is calculated. This allowable stacking height is determined by the original design height of the storage area, the actual slope, the preset benchmark slope, and the preset slope threshold. The actual stacking height is then reduced based on the allowable stacking height.

[0076] In this specific application, the initial design stack height of storage area C is 2m (capacity 200m³). 3 Using existing tilt sensors, the slope gradient is monitored in real time as it gradually increases from 15° to 24° (in this embodiment, the preset safety threshold is 25°, and the difference threshold is 1°). According to the formula: Allowable stacking height = 2m (original design height) × (1 - (24° (actual slope) - 15° (baseline slope)) / 10° (slope threshold)) = 0.2m, the stacking height is dynamically adjusted to 1.8m, and the capacity is correspondingly reduced to 180m³. 3 At the same time, the excess 20m will be automatically allocated. 3 The earthwork is moved to the backup area D to avoid overloading the slope in area C. It should be noted that the backup area D in this embodiment is based on the area used as a backup during actual construction.

[0077] By utilizing the above, the storage capacity can be dynamically adjusted according to safety, maximizing the use of storage space while ensuring slope stability and avoiding potential slope collapse accidents.

[0078] Specifically, dynamic equilibrium includes:

[0079] Based on the dynamically stripped and stored earthwork volumes, earthwork allocation instructions are generated. These instructions include:

[0080] When the volume of dynamically stripped earthwork exceeds the volume of dynamically stored earthwork, it should be allocated to the backup storage area with the shortest transport distance.

[0081] When the volume of dynamically stripped earthwork is less than the volume of dynamically stored earthwork, the subsequent stripping plan shall be adjusted.

[0082] In the specific application of this embodiment, the dynamic stripping earthwork volume (Area A, 89m³) is calculated. 3 +B area 24.5m 3 =113.5m 3 () greater than the dynamic storage earthwork volume (180m³ in Zone C) 3 ×80%=144m 3 After deducting the 35m already stored 3 109m can be used afterwards 3 When this occurs, a redistribution instruction is generated: The excess 4.5m... 3 Priority was given to allocating to backup zone E, 1.2km away (rather than zone F, 2.5km away). Subsequently, zone B was used because the actual stripping volume was only 20m³. 3Automatically adjust the stripping plan for Area A the following day, increasing by 5m. 3 To make up the difference.

[0083] By utilizing dynamic balancing, the earthwork transportation distance can be shortened, and transportation costs can be reduced. At the same time, by adjusting the stripping plan in real time, the utilization rate of the storage area can be ensured, and resource idleness can be avoided.

[0084] Specifically, the excavation area is determined based on the results of soil quality analysis, including:

[0085] The corresponding excavation location, excavation area, and excavation depth are determined based on soil quality analysis;

[0086] The excavation zone is determined by the excavation location, excavation area, and excavation depth.

[0087] It should be noted that the excavation area in this embodiment corresponds to the actual construction area. Soil quality analysis is performed on the soil within this construction area. This analysis is conducted by sampling soil samples and sending them to a laboratory for testing to obtain the corresponding soil grade. This soil grade is used to guide the reuse of the soil. As a preferred implementation method in this embodiment, the static stripping earthwork volume is calculated using the formula for calculating the stripping zone earthwork volume. The formula for calculating the stripping zone earthwork volume is:

[0088]

[0089] in:

[0090] Q s The calculated static stripping earthwork volume;

[0091] S i Let i be the excavation area of ​​the i-th excavation zone;

[0092] H i Let be the excavation depth of the i-th excavation zone, which can be the average excavation depth obtained from the analysis results based on soil quality analysis;

[0093] f s The stripping rate is affected by factors such as the stripping construction process and project scale, and is generally greater than or equal to 90%. However, this embodiment follows the principle of "stripping as much as possible" and takes into account the losses during the construction process, so a value of 95% is used.

[0094] Specifically, the static storage volume of earthwork is determined based on the preset storage area, including:

[0095] The static storage earthwork volume is determined based on the preset storage area and its corresponding preset storage height.

[0096] It should be noted that the preset storage area in this embodiment is an area reserved for storing soil based on the static stripping earthwork volume before construction begins. In practical applications, it can be an open space with a metal shed or other covering. As a preferred embodiment, the static storage earthwork volume is calculated using the earthwork volume calculation formula for the storage area. The earthwork volume calculation formula for the storage area is as follows:

[0097]

[0098] in:

[0099] Q b The calculated static earthwork volume;

[0100] S j Let J be the storage area of ​​the j-th storage area;

[0101] H j Let j be the storage height of the j-th storage area;

[0102] K is the safety stacking factor, which corresponds to the calculation of the allowable stacking height in the dynamic adjustment and is a design consideration in the preliminary stage.

[0103] Specifically, static equilibrium means that when designing a storage area, the static storage volume of that storage area is greater than or equal to the static stripping volume.

[0104] Based on the above, the determination of the excavation area, the calculation of the static stripping volume, and the static storage volume provide a data basis for the design of the storage area, thereby achieving static balance at the beginning of the soil stripping and reuse design.

[0105] The second aspect of this embodiment discloses as follows: Figure 2 The method shown is a soil stripping and reuse method applicable to the soil stripping and reuse system described above, the method comprising:

[0106] S1: Before soil stripping, soil quality analysis is conducted on the excavation area. Based on the results of the soil quality analysis, the soil is stripped and reused. Before the purpose of reuse is determined, the soil is centrally stockpiled.

[0108] S2: Determine the static earthwork volume based on the preset storage area; determine the dynamic earthwork volume based on the monitoring of the storage area;

[0109] S3: Static balance is performed based on the volume of stripped soil and the volume of stored soil. This static balance is used to characterize the quantitative balance relationship between the excavation area and the storage area under static conditions. Dynamic balance is performed based on the volume of stripped soil and the volume of stored soil. This dynamic balance is used to characterize the quantitative balance relationship between the excavation area and the storage area under dynamic conditions. This dynamic relationship is determined by the soil transportation process after stripping and the monitoring of the storage area.

[0110] It should be noted that the soil stripping and reuse method of this embodiment corresponds to the aforementioned soil stripping and reuse system. Therefore, any content not specifically described in the soil stripping and reuse method of this embodiment, including but not limited to functional definitions, working principles, and technical effects, can be referred to the description in the aforementioned soil stripping and reuse system, and will not be repeated here.

[0111] In summary, the soil stripping and reuse system and method of this embodiment constructs a precise control system for the entire process from soil stripping to storage. By acquiring dynamic parameters such as topographic slope and transportation losses in real time, and combining them with soil quality analysis results, the effective amount of stripped soil is accurately calculated, significantly improving the accuracy of data calculation. The storage area determination module monitors slope stability in real time through tilt sensors and dynamically adjusts stacking parameters to maximize the use of storage space while ensuring safety. The soil balance module, based on dynamic stripping and storage data, achieves coordinated optimization of static planning and dynamic response, intelligently allocates soil resources, and reduces transportation redundancy and resource idleness. It effectively solves the problem of the disconnect between traditional static design and dynamic construction scenarios, forming a data-driven, safe, and efficient soil reuse technology solution, providing a new solution for land resource protection and ecological restoration.
