Description

Technical Field

[0001] The present application relates to the technical field of electric power transportation, and in particular to a low-impact construction treatment method suitable for Gobi power transmission line construction. Background Art

[0002] When constructing power transmission lines in the Gobi Desert, the foundation construction of the transmission tower requires piles to be driven into the ground, especially in Gobi Deserts with complex or soft geological conditions, which usually require piling or drilling. Pile drivers will produce strong impact noise when working, especially hammer pile drivers, whose impact sound has strong penetration and can be transmitted over long distances. Drilling construction will also produce a large continuous noise.

[0003] Although the Gobi region has low species diversity, it is still home to some unique species that are drought- and cold-resistant, such as Gobi dryland animals, desert reptiles, and migratory birds. Continuous noise can interfere with wildlife foraging, reproduction, and rest. Many animals rely on hearing to sense danger or find prey, and noise can interfere with their hearing acuity, affecting their ability to hunt or avoid predators.

[0004] Since the ecological balance in the neighboring areas is relatively fragile, human activities can easily affect the ecological balance, especially the impact of construction on the environment is unique. In urban environments, noise propagation will be blocked and reflected by structures such as buildings and trees, so the propagation distance is short. Buildings, roads, greenery, etc. will produce multiple reflections, resulting in rapid attenuation of noise energy. The terrain in the Gobi region is usually relatively flat and open, lacking tall buildings or dense vegetation as barriers, so noise can be transmitted over longer distances in an open environment. In addition, the air density in the Gobi region is low, especially under high temperature and dry weather conditions, the sound decays more slowly in the air and the propagation range is wider. Especially at night or when the weather is calm and the wind speed is low, the propagation distance of noise will be further increased. Summary of the invention

[0071] 1. This application systematically obtains and analyzes the basic terrain data, actual construction conditions and real-time meteorological data of the construction area to construct a noise propagation model, thereby accurately calculating the noise impact of construction activities on the preset ecological area. By monitoring and evaluating the noise intensity during the first construction period and comparing it with the preset noise threshold, the scheme can promptly identify the adverse effects that construction noise may have on the ecological environment.

[0073] 3. By inputting the first meteorological data into the noise propagation model, the potential impact of the noise in the construction area on the preset ecological area is effectively evaluated. By determining the first direction, wind direction and wind speed of noise propagation, and combining the calculation of relative direction, the scheme can comprehensively analyze the effect of environmental conditions on noise propagation, and then calculate the first noise intensity. This process not only improves the accuracy of noise propagation prediction, but also can promptly identify construction activities that may have an impact on the ecological area. When the calculation results show that the noise intensity reaches or exceeds the preset threshold, the construction party can quickly take corresponding adjustment measures, such as changing the construction time or method, to reduce the interference of noise on the surrounding ecological environment.

[0078] In order to enable technicians in this field to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

For example, multiple systems refer to two or more systems, and multiple screen terminals refer to two or more screen terminals. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the indicated technical features.

The terms "include", "comprise", "have" and their variations all mean "including but not limited to", unless otherwise specifically emphasized.

[0081] When constructing power transmission line foundations in the Gobi region, piling and drilling operations will generate strong and continuous noise, especially the impact sound of hammer pile drivers, which can travel a long distance and have a significant impact on the ecological environment. Although the Gobi has low species diversity, it is still a habitat for drought-resistant and cold-resistant animals. Continuous noise may interfere with the foraging, reproduction and risk avoidance of wild animals. Compared with cities, the Gobi has an open terrain and lacks noise barriers, which causes the noise to travel farther. Especially when it is hot, dry or windy, the noise propagation range is further expanded, posing a threat to the fragile ecosystem.

[0082] This embodiment discloses a low-impact construction treatment method suitable for Gobi power transmission line construction, referring to Figure 1 , including the following steps S110-S150:

[0083] S110, obtaining basic terrain data of the construction area.

[0084] The low-impact construction processing method for Gobi power transmission line construction disclosed in the embodiment of the present application is applied to a server, and the server includes but is not limited to electronic devices such as mobile phones, tablet computers, wearable devices, PCs (Personal Computers), etc., and can also be a background server running the low-impact construction processing method for Gobi power transmission line construction. The server can be implemented as an independent server or a server cluster composed of multiple servers.

[0085] Using remote sensing technology to obtain terrain data for a large area can provide fast and comprehensive basic information. Alternatively, drones equipped with high-resolution cameras can be used for aerial photography, and existing topographic maps and literature can be used to supplement basic terrain data.

[0086] S120, build a noise propagation model based on the actual construction situation of the project and basic terrain data.

[0087] In one possible implementation, a noise propagation model is constructed according to the actual construction conditions of the project and basic terrain data, specifically including: determining the construction machinery and equipment and the operation links according to the actual construction conditions of the project; determining the noise source characteristics of the noise source based on the construction machinery and equipment and the operation links corresponding to the construction machinery and equipment, the noise source characteristics including the sound power level; determining the influencing parameters of the terrain on noise propagation according to the basic terrain data, the influencing parameters including reflection parameters, absorption parameters and shielding parameters; calculating the intensity of noise propagating from the noise source to different areas according to the noise source characteristics and the influencing parameters; and constructing a noise propagation model according to the calculation results.

[0088] Specifically, list all the main mechanical equipment used in the construction process, such as pile drivers, excavators, concrete pump trucks, etc. Divide the construction process into different operation phases, and the equipment working mode in each phase may be different, such as startup, full load operation, no-load operation, shutdown, etc. Use an accurate sound level meter (Sound Level Meter) or recording equipment to measure the sound pressure level at specific measurement points around each mechanical equipment in accordance with international standards such as ISO 3744 or ISO 9614. For each operation phase, select multiple measurement points and record the sound pressure level at each point. The measurement points can be laid out according to the type of equipment, the height of the noise source, and the characteristics of the construction area.

[0089] The measured sound pressure level L p Converted to sound power level L w :

[0090] L w =L p +10log 10 (S)+10log 10 (Q)

[0091] Where S is the surface area of ​​the measurement area (in square meters), usually the area of ​​a sphere or hemisphere, and Q is the directivity factor of the noise source. Select an appropriate value based on the noise directivity of the mechanical equipment.

[0092] Among them, the sound power level represents the total energy emitted by the noise source per unit time. It is the basic value of mechanical equipment noise. The power of sound usually spans a very large range, and the use of logarithms can compress the large range of values ​​into a manageable range. 10 is one of the commonly used logarithmic bases, which converts physical values ​​into logarithmic values ​​that are easier to handle and compare. The calculation of power level and sound pressure level usually involves square relationships. For example, the intensity of sound pressure is related to the square of sound power, so the constant 10 is used in the conversion to handle this relationship. For the calculation of sound pressure level, the constant 10 corresponds to the logarithmic relationship of power. And the definition of decibel has been standardized in acoustics, using a logarithmic function with a base of 10. The use of 10 as the base of the logarithmic calculation in the formula ensures that the results are consistent with international acoustic standards.

[0093] For each operation link i, the measured sound pressure level L p i Converted to sound power level L w i , and then sort out the sound power level L of each stage w i . Record the duration of each operation link t i, to ensure that you know exactly how long the equipment is operating in different states. For example, a pile driver may be operating at full power for longer than when it is starting and stopping. Then calculate the average sound power level for the entire operating cycle using the given formula:

[0094]

[0095] Among them, L w is the sound power level, L w i is the sound power level converted from the sound pressure level of the i-th operation stage, t i is the duration of the ith operation stage, and T is the total time of the entire operation cycle.

[0096] The essence of this formula is to weight the sound power level of each operation stage according to its time proportion to obtain the overall sound power level of the entire construction cycle.

[0097] Furthermore, based on the acquired basic terrain data, the influencing parameters, including reflection parameters, absorption parameters, and shielding parameters, are calculated, and the reflectivity of the sound waves is calculated based on the ground characteristics (such as sand, hard ground, and grass) in the construction area. Generally, the reflectivity of sound waves on hard surfaces (such as concrete) is higher, while on soft surfaces (such as sand), it is lower. The reflection parameters are specifically calculated using the following formula:

[0098]

[0099] Among them, L multi-reflection is the reflection parameter, L source (r0) is the initial sound pressure level, r is the distance between the construction area and the preset ecological area, r0 is the initial reference distance, which is the propagation distance calculated from the noise source, α i is the reflection coefficient of the i-th reflection surface, r i is the distance the sound wave travels after each reflection, β i is the attenuation coefficient of each reflection.

[0100] In the formula -20log 10 (r / r0) represents the free field propagation loss, which indicates the attenuation of noise when it propagates from the reference distance r0 to the actual distance r. The 20 here is still related to the square relationship of the sound pressure. During the propagation process, the sound pressure will decrease as the distance increases. Since the sound pressure level is inversely proportional to the square of the distance, 20 is used instead of 10 in the logarithmic formula. It is based on the energy attenuation caused by the increase in distance when the sound wave propagates in free space, which is called "distance attenuation". α iis the reflection coefficient of the i-th reflecting surface, which indicates the proportion of energy reflected back when the sound wave hits the surface. Different ground surfaces or obstacles have different reflection coefficients. Hard ground surfaces (such as concrete) have high reflectivity, while soft ground surfaces (such as sand) have low reflectivity. i is the attenuation coefficient after the i-th reflection, taking into account the absorption and loss of sound wave energy during reflection, and is usually related to the sound absorption properties of the material. i is the distance the sound wave propagates after the i-th reflection. Each reflection will change the propagation path of the sound wave, affecting the further attenuation of the sound wave energy.

[0101] The summation part of the formula is a correction term for multiple reflections. After each reflection, the reflection coefficient of the reflecting surface affects the energy reflectivity of the sound wave. When the reflection coefficient is high, the surface will reflect more energy, and the noise will propagate over a longer distance. After reflection, the sound wave energy will continue to decay as the propagation distance increases. The attenuation coefficient is used to represent the energy loss of the sound wave after each reflection. This part of the formula takes into account that in a complex environment, the sound wave may reflect multiple times from different surfaces, and each reflection will affect the propagation path and intensity of the sound wave.

[0102] This is particularly important for evaluating the propagation of sound waves in open environments with no obvious obstacles, such as the Gobi Desert.

[0103]

[0104] Among them, L source (r0) is the initial sound pressure level, L w is the sound power level, r0 is the initial reference distance. 2πr0 2 It is the area of ​​the sphere starting from the sound source, which is used to reflect the increase in area when the sound wave propagates spherically in free space. The function of this part is to consider the diffusion effect of sound in space, that is, as the distance increases, the energy density of sound in spherical space will gradually decrease.

[0105] Calculate the sound absorption characteristics of air according to the ground type and climatic conditions. Especially in hot and dry weather, the sound absorption capacity is relatively weak. The absorption parameter can be calculated by the following formula:

[0106]

[0107] Where, ΔL air (f,r) is the absorption parameter, f is the frequency of the sound wave, T is the ambient temperature, P is the air pressure, ρ is the air density, and r is the distance between the construction area and the preset ecological area.

[0108] Among them, 1.84×10-11 is a physical constant used to adjust the proportional relationship in the air absorption formula. When sound waves propagate in the air, they encounter the viscous resistance and thermal conduction effect of air molecules. Both effects consume the energy of the sound waves, causing the noise to gradually attenuate during propagation. 1.84×10-11 is the result of combining multiple physical constants such as the thermal conductivity and viscosity coefficient of air. It is a correction factor that combines theoretical formulas with experimental data.

[0109] f is the frequency of the noise, measured in Hertz (Hz). The higher the frequency, the stronger the absorption of the noise in the air. High-frequency sound waves (such as sharp sounds) are more easily absorbed in the air, so the square of the frequency is proportional to the absorption of the noise. T is the temperature of the air, measured in Kelvin (K). Temperature affects the speed of movement of air molecules and the speed of sound wave propagation. The higher the temperature, the smaller the absorption loss when the sound wave propagates, so the absorption loss is inversely proportional to the square of the temperature. P is the pressure of the air, measured in Pascals (Pa). Air pressure affects the molecular density and collision frequency, so at high pressures, the sound wave energy loss will be greater. The higher the atmospheric pressure, the greater the absorption loss of sound waves propagating in the air.

[0110] Identify natural barriers (such as hills, trees, etc.) within the construction area and evaluate their shielding effect on noise propagation, determine the attenuation of the shielding effect, and the shielding parameters are calculated using the following formula:

[0111] ΔL shielding =10log 10 (1+10·e -λH )

[0112] Where, ΔL shielding is the shielding parameter, λ is the wavelength of the sound wave, and H is the height of the obstacle.

[0113] When noise encounters obstacles (such as buildings, mountains, sand dunes, etc.) during propagation, the obstacles will block or reflect the sound waves, resulting in a reduction in the energy of the sound waves. Generally, high-frequency sound waves are easier to shield than low-frequency sound waves because high-frequency sound waves have shorter wavelengths and are difficult to bypass obstacles.

[0114] Based on the environmental characteristics and noise source characteristics, select a suitable noise propagation model, such as ISO 9613-2, USEPA model or other models suitable for the Gobi region. Input the sound power level, reflection parameters, absorption parameters, shielding parameters, etc. into the model. Use the noise propagation formula to calculate the intensity of noise propagating from the noise source to different areas, usually in the following form:

[0115] L final (r,f)=L multi-reflection -ΔL air (f,r)-ΔL shielding

[0116] Among them, L final (r, f) is the intensity of noise propagating from the construction area to the preset ecological area, L source (r0) is the initial sound pressure level, L multi-reflection is the reflection parameter, ΔL air (f,r) is the absorption parameter, ΔL shielding is the shielding parameter.

[0117] S130, obtaining first meteorological data of the construction area during a first construction period.

[0118] First of all, it is necessary to clarify the first construction period, that is, the specific time period of construction activities (such as specific start and end dates, daytime or nighttime construction time). This period will affect the collection and analysis of meteorological data. Meteorological stations near the construction area provide accurate historical and real-time meteorological data. These meteorological stations are usually operated by government meteorological departments or specialized meteorological service agencies and can provide long-term meteorological observation data. Regional meteorological data collected by meteorological satellites can cover remote areas that cannot be covered by ground meteorological stations, especially for more remote areas such as the Gobi Desert. In remote or special terrain conditions, drones can be used to carry meteorological equipment, or mobile meteorological stations can be directly deployed at the construction site to collect real-time meteorological data.

[0119] For noise propagation, the key meteorological data that need to be obtained include: wind direction. The direction of wind flow has a significant impact on the path of noise propagation, especially in open areas. Wind speed. The greater the wind speed, the direction and speed of sound wave propagation will change. Wind speed can accelerate or slow down the propagation of sound waves. Temperature. The air temperature has an impact on the speed of sound propagation. Generally, the higher the temperature, the faster the sound propagates, but its attenuation rate will also decrease accordingly. Humidity. The humidity in the air affects the degree of absorption of sound waves in the air. The higher the humidity, the stronger the air's sound absorption capacity. Air pressure. Atmospheric pressure has a slight effect on the attenuation and speed of sound waves, especially at high altitudes or in low pressure environments.

[0120] S140, inputting first meteorological data into a noise propagation model to obtain a first noise intensity for a preset ecological area calculated by the noise propagation model.

[0121] First, determine the direction in which the noise propagates from the construction area to the preset ecological area, which is called the first direction. This direction can be determined by mapping the geographical distance and orientation between the construction area and the ecological area, usually using a two-dimensional or three-dimensional map system to confirm the propagation path. During the first construction period, obtain the wind direction (second direction) and wind speed in the construction area. Wind direction and wind speed are collected through meteorological data. Wind direction affects the direction of noise propagation, while wind speed directly affects the speed and distance of sound propagation.

[0122] By comparing the first direction of noise propagation with the wind direction (second direction), the relative direction of the two is determined. This means calculating the angle between the noise propagation direction and the wind direction, which is marked as θ. When the wind direction is the same as or opposite to the noise propagation direction, θ is 0 degrees or 180 degrees, respectively. Based on the relative direction of the noise propagation direction and the wind direction, as well as the wind speed, the impact of the environment on noise propagation is calculated using the following formula:

[0123]

[0124] Where, ΔL air '(f,r) is the environmental parameter, r is the distance between the construction area and the preset ecological area, f is the frequency of the sound wave, T is the ambient temperature, P is the air pressure, ρ is the air density, V w is the wind speed, θ is the relative direction, and c is the speed of sound.

[0125] Wind speed and direction have an important impact on noise propagation. If the wind direction is the same as the noise propagation direction, the wind speed will enhance the propagation effect of the sound waves, causing the noise energy to propagate further; if the wind direction is opposite, the wind speed will weaken the propagation of the sound waves, causing the noise energy to decay faster.

[0126] After substituting environmental parameters into the noise propagation formula, the final noise propagation intensity can be obtained. The noise emitted by construction equipment will gradually decay with increasing distance, and the decay rate is affected by factors such as wind speed, wind direction, temperature, and air density. Through the environmentally corrected noise propagation model, the noise intensity of the preset ecological area can be obtained, and then its potential impact on the local environment and ecology can be evaluated.

[0127] S150: If it is determined that the first noise intensity is greater than or equal to a preset threshold, adjusting a first construction period of the construction area according to the first meteorological data.

[0128] In one possible implementation, the first construction period of the construction area is adjusted according to the first meteorological data, specifically including: obtaining the second construction period and the second meteorological data of the construction area; inputting the second meteorological data into the noise propagation model to obtain the second noise intensity for the preset ecological area calculated by the noise propagation model; if it is determined that the second noise intensity is less than a preset threshold, then determining that the construction time of the construction area is the second construction period.

[0129] Specifically, according to the project schedule and construction plan, select a new construction period as the second construction period. This may be a different time period of the day or a period a few days later, depending on the changes in meteorological conditions. Use meteorological monitoring equipment or services to collect meteorological data for the second construction period, including wind speed, wind direction, temperature, humidity, and air pressure. Ensure that the data obtained is accurate and timely.

[0130] Ensure that the established noise propagation model can handle the newly acquired meteorological data. The model should be able to handle different input variables (such as wind speed, wind direction, etc.) to calculate the noise intensity. Input the second meteorological data into the noise propagation model and update the model parameters to ensure that the model can accurately calculate according to the latest meteorological conditions.

[0131] After inputting the second meteorological data, run the noise propagation model to calculate the second noise intensity for the preset ecological area. The model will re-evaluate the impact of noise propagation based on the new data, including noise attenuation, wind impact, etc. Record the second noise intensity value output by the model for subsequent comparison and judgment. Set a noise intensity threshold in advance, usually based on the noise tolerance level or ecological protection requirements of the ecological area. This threshold is used to judge the impact of construction noise on the ecological area. Compare the calculated second noise intensity with the preset threshold. If the second noise intensity is less than the threshold, it means that construction in the second construction period will not have a significant impact on the ecological area. If the second noise intensity is lower than the preset threshold, determine to carry out construction in the second construction period. Notify the construction team to arrange the work according to the new construction schedule to ensure compliance with the construction time and plan. If the second noise intensity is higher than the preset threshold, consider continuing to monitor the meteorological conditions and find other suitable construction time periods for adjustment. The construction team should have the ability to respond flexibly and formulate construction plans based on real-time meteorological conditions.
