[0021] The environmentally friendly dredging and filling method provided by the present invention can comprehensively evaluate the impact of construction on the surrounding environment by obtaining detailed actual environmental information of the area to be dredged and filled, so as to make adequate planning and preparation before construction. The construction area and the conservation area are clearly divided to ensure that construction activities will not directly damage or interfere with natural resources or ecological environments that need to be protected. The resources to be conserved in the construction area are transferred, and special protective measures are implemented in the conservation area, which effectively reduces the negative impact of construction activities on the ecology and protects biodiversity. Example

[0022] An environmentally friendly dredging and filling method provided by an embodiment of the present invention is as follows: Figure 1 As shown, the method includes: S110, obtaining actual environmental information of the area to be dredged and filled, the actual environmental information including land surface environmental information and underwater environmental information; S120, determining the construction area and conservation area according to the actual environment information and the construction drawing information; S130, transfer the resources to be conserved in the construction area, implement protective measures in the conservation area and then carry out dredging and filling operations; S140. Carry out maintenance and construction work within the conservation area.

[0023] In this way, with the help of comprehensive analysis of actual environmental information and construction drawing information, the construction scope and operation method can be determined more accurately, thereby improving construction efficiency. Clarifying the boundaries of the construction area and the conservation area will help construction personnel clarify their responsibilities, reduce misoperations, and improve overall construction quality and safety.

[0024] The environmental dredging and filling method emphasizes the protection of the environment and the rational use of resources, which is in line with the concept of sustainable development. By carrying out maintenance and construction operations in the conservation area, not only the ecological environment is restored, but also the sustainable development of the area is promoted, such as ecotourism and ecological education. The environmental dredging and filling method can reduce the environmental damage and ecological compensation costs caused by construction activities, thereby reducing project costs. By protecting the ecological environment and natural resources, the ecological value of the surrounding areas is enhanced, the social recognition of environmentally friendly projects is enhanced, and it is conducive to improving the social image and reputation of the enterprise.

[0025] The land surface environment information includes at least one of plant information, animal information and earth and stone information. The water environment information includes water organism information and water resource information.

[0026] More specifically, it can be to record the plant species, quantity, distribution, growth status (such as height, crown width, health status, etc.) and vegetation coverage in the area to be dredged and filled. Use a combination of field surveys and remote sensing monitoring. Field surveys can obtain detailed information on plant species and growth status, while remote sensing monitoring can quickly obtain vegetation coverage over a large area. Record the animal species, quantity, distribution, living habits and relationship with human activities in the area to be dredged and filled. Focus on rare, endangered or protected animal species. Use methods such as animal tracking, ecological footprint analysis, and infrared camera monitoring. These methods can help us understand information such as the range of animals, living habits, and migration routes.

[0027] Record the soil type, distribution, thickness, water content, bearing capacity, and the number, size, and distribution of stones in the area to be dredged and filled. Use geological exploration, soil sampling, in-situ testing, and other methods. These methods can help us understand the physical and chemical properties of the soil, as well as the distribution and number of stones.

[0028] Understandably, you can also record water quality parameters such as dissolved oxygen, pH, conductivity, turbidity, heavy metal content, organic pollutant concentration, etc. in the area to be dredged and filled. Use water quality monitoring instruments for on-site monitoring, or collect water samples and send them to the laboratory for analysis. These methods can provide accurate water quality data to help us understand the pollution status and ecological health of the water body. Record information such as the species, quantity, distribution, and community structure of aquatic organisms in the area to be dredged and filled. Focus on biological groups such as benthic animals, zooplankton, and fish.

[0029] The acquired land and water environment information will be collated and analyzed to form a detailed investigation report. The report may include the following: geographical location, area and scope of the area to be dredged and filled; land environment information, including plant species, quantity, distribution and growth status, animal species, quantity, distribution and living habits, as well as soil type, distribution and carrying capacity; water environment information, including water quality parameters, aquatic organism species and quantity, community structure and hydrological parameters; based on the investigation and analysis results, environmental protection measures and suggestions for dredging and filling projects are proposed.

[0030] More specifically, after determining the construction area and the conservation area, an isolation zone can be set up between the construction area and the conservation area. Specifically, an isolation zone can be set up through anti-fouling curtains. Through the porosity and self-cleaning materials of the isolation zone, the suspended matter generated by the construction can be blocked to the greatest extent, thereby reducing the impact on the conservation area. More specifically, anti-fouling curtains can be set up outside the mangroves to block suspended matter, and the mangroves adjacent to the construction area can be protected in situ. At the same time, mangrove transplantation and off-site restoration construction are also carried out, off-site restoration is carried out at 3 times the occupied area, and 5 years of management and maintenance are implemented to ensure that the number of mangroves in the area does not decrease due to project construction.

[0031] In this way, by setting up an isolation zone between the construction area and the conservation area, the suspended matter generated by the construction is effectively blocked from entering the conservation area, significantly reducing the impact of construction activities on the ecological environment. Anti-fouling curtains are set up outside the mangroves to provide on-site protection for the mangroves, reduce the damage of suspended matter to their growth environment, and help protect this important ecosystem. Carry out local transplantation and off-site restoration of mangroves, and implement off-site restoration at 3 times the occupied area, which not only makes up for the occupation of mangrove area by construction, but also increases the overall area of ​​mangroves, which helps to improve regional ecological diversity. The implementation of 5 years of management and protection ensures the survival rate of mangroves during the restoration process and further consolidates the results of ecological restoration.

[0032] Understandably, the porosity and material of the anti-pollution curtain can be strictly screened to ensure that it can effectively block suspended matter while maintaining good water permeability to avoid secondary pollution to the surrounding environment. The installation of the anti-pollution curtain must be firm and reliable, and able to withstand the impact of wind, waves and water flow during the construction process to ensure the isolation effect. When setting up anti-pollution curtains outside the mangroves, the growth characteristics and ecological environmental needs of the mangroves must be considered to ensure that the anti-pollution curtains do not oppress the mangroves or block the sunlight. When mangroves are transplanted nearby and restored in other places, suitable transplantation and restoration sites must be selected to ensure that the mangroves can grow well in the new growth environment. During the 5-year management and maintenance period, the growth status of mangroves must be monitored regularly, and necessary maintenance measures must be taken in a timely manner, such as weeding, fertilization, pest and disease control, etc., to ensure the survival rate of mangroves.

[0033] More specifically, the resources to be conserved in the construction area may be transferred, and dredging and filling operations may be carried out after protective measures are implemented in the conservation area, including: transplanting the plant resources to be conserved in the construction area nearby or / and restoring them at another location.

[0034] Among them, protective measures can include the establishment of a mechanism for underground water gushing out during excavation to rationally utilize groundwater to solve the problem of water use in production; for sewage generated by production and life, sewage discharge inspection and treatment equipment have been established, and a sewage treatment sedimentation tank has been specially built. The treated water is used for greening irrigation and sprinkling to reduce dust.

[0035] Domestic sewage treatment systems and production water recycling systems can also be used at the project site and on-site respectively, and the entire process can be automated.

[0036] In this way, by transplanting or restoring the plant resources to be conserved in the construction area nearby, the biodiversity in the construction area is effectively protected, and the damage to the ecological environment caused by construction activities is reduced. Transplantation and restoration construction not only help maintain the integrity of the original ecosystem, but also promote the reproduction and development of plant resources in the new growth environment, and achieve ecological restoration and sustainable development. The sewage generated by production and life is effectively treated, and sewage discharge inspection and treatment equipment and sewage treatment sedimentation tanks are established to ensure that the sewage is discharged in compliance with the standards and reduce water pollution. The project site and the site use a domestic sewage treatment system and a production water recycling system respectively, realizing full-process automation, improving water resource utilization efficiency, and reducing energy consumption and carbon emissions. Through the application of green construction technology, such as sprinkling water to reduce dust, dust pollution during construction is effectively reduced, the construction environment is improved, and green development is promoted. Through reasonable resource conservation and ecological restoration measures, the ecological compensation costs caused by construction activities are reduced, and the project cost is reduced. The rational use of water resources and the effective treatment of sewage not only reduce the waste of water resources and pollution treatment costs, but also improve construction efficiency and shorten the construction period.

[0037] Understandably, before transplanting plant resources, especially mangroves and protected plants, a detailed investigation can generally be conducted to understand the plant species, quantity, growth status and distribution to ensure the feasibility and scientificity of the transplant. During the transplantation process, necessary protective measures must be taken, such as moisturizing, sun protection, and pest and disease prevention, to ensure the survival rate of plants during the transplantation process. When resuming construction in a different location, a suitable location must be selected to ensure that the plants can grow well in the new growth environment, and appropriate maintenance measures must be taken, such as fertilization, irrigation, pruning, etc.

[0038] The use of underground water must be tested to ensure that the water quality meets the production water standards. Sewage discharge inspection and treatment equipment must be regularly maintained and repaired to ensure the normal operation of the equipment and the discharge of sewage meets the standards. Sewage treatment sedimentation tanks must be cleaned regularly to prevent sediment accumulation from affecting the treatment effect.

[0039] Domestic sewage treatment systems and production water recycling systems need to achieve full-process automation to reduce manual intervention and improve treatment efficiency. The application of green construction technologies such as water sprinkling and dust reduction needs to be adjusted in a timely manner according to the construction environment and climatic conditions to ensure better results.

[0040] More specifically, the resources to be conserved in the construction area can be transferred, and protective measures can be implemented in the conservation area before dredging and filling operations are carried out, including: the animal resources to be conserved in the construction area can be driven away and / or relocated. Among them, there are many aquatic organisms. In order to reduce the impact of construction operations on the aquatic environment of the Qin River, fish-driving equipment can be purchased in a unified manner. Before each underwater reef blasting operation, fish-driving operations can be carried out to drive fish away from the blasting danger zone, ensure the safety of the blasting operation, and protect fish from harm. At the same time, in order to protect the diversity of terrestrial animals, terrestrial animal-driving equipment can be purchased in a unified manner, and various animals in the construction area can be driven away regularly to reduce interference with animal habitats and protect the ecological environment.

[0041] Specifically, we can relocate slow-moving animal resources such as oysters to reduce the pollution of such organisms caused by construction, optimize the pipeline layout plan, and avoid the relevant areas for the drainage pipeline. We can also use wild oyster parents, carry out seed breeding, screen parents, and carry out seed breeding in batches. After cultivation, we can obtain oysters with a length of more than 7 cm to ensure the needs of parent group renewal and proliferation of adult shellfish for release.

[0042] In this way, by driving away or relocating the animal resources to be conserved in the construction area, the disturbance of construction activities on animal habitats is effectively reduced, and the diversity of animal resources is protected. In particular, targeted protection measures are taken for aquatic organisms such as fish and oysters, such as the use of fish-driving equipment and the migration of slow-moving animal resources, to ensure that the impact of construction activities on aquatic ecosystems is minimized. By carrying out seed breeding work, selecting parents and cultivating adult oysters, not only the renewal of parent groups is guaranteed, but also sufficient adult resources are provided for reproduction and release, which helps to restore and improve the biodiversity and stability of aquatic ecosystems.

[0043] Fish-driving operations were carried out before underwater reef blasting to ensure the safety of blasting operations, protect fish from harm, and reduce the potential threat of construction activities to aquatic ecosystems. By optimizing the pipeline layout plan, the mud discharge pipeline avoided the relevant area, reducing the pollution of slow-moving animal resources such as oysters during construction, and improving the environmental performance of construction activities. By carrying out seedling breeding and proliferation and release, not only the recovery of aquatic ecosystems was promoted, but also the regional ecological value was improved, providing favorable conditions for sustainable development activities such as ecotourism and ecological education.

[0044] Understandably, before driving away animal resources, a detailed investigation is required to understand the species, number, living habits and distribution of animals to ensure the feasibility and scientificity of the driving plan. During the driving process, necessary protection measures need to be taken, such as setting up buffer zones and using harmless driving methods, to ensure that animals are not harmed during the driving process. For slow-moving animal resources such as oysters, migration is required. When migrating, appropriate migration sites need to be selected and the survival rate during the migration process needs to be ensured. Fish driving equipment needs to be purchased in a unified manner and ensure that the equipment performance is stable, safe and reliable. Before each underwater reef blasting operation, fish driving operations need to be carried out to ensure that the fish driving effect is good and will not cause harm to fish. When optimizing the pipeline layout plan, the distribution of animal resources needs to be fully considered to ensure that the mud discharge pipeline avoids the relevant area and reduce the impact of construction on aquatic organisms. For seedling breeding, suitable wild oyster parents need to be selected and strictly screened and cultivated. During the cultivation process, a suitable growth environment needs to be provided to ensure the healthy growth of seedlings. Before releasing the adult oysters, the quality of the oysters must be tested to ensure that the released adult oysters have good survival ability and reproductive potential. When releasing the oysters, the appropriate location and time must be selected to ensure the best release effect.

[0045] More specifically, the photovoltaic power generation area can be determined based on the actual environmental information and construction drawing information. Specifically, the photovoltaic power generation area can be built through the excavated earth and stone. In this way, through the use of photovoltaics, the consumption of standard coal can be saved every year, and the emission of carbon dioxide and sulfur dioxide can be reduced, further achieving green environmental protection.

[0046] In this way, by directly using the excavated earth and stone to build the photovoltaic power generation area, the maximum utilization of resources is achieved, the stacking and transportation of earth and stone are avoided, and the energy consumption and emissions during the construction process are reduced. As a clean energy, photovoltaic power generation can save a large amount of standard coal consumption every year, significantly reduce the emission of pollutants such as carbon dioxide and sulfur dioxide, help improve air quality, and achieve green environmental protection goals. The construction of photovoltaic power generation areas not only meets the electricity demand for construction, but also sells excess electricity to the grid to generate economic benefits. At the same time, by reducing the consumption of traditional energy such as coal, energy costs are reduced, and environmental pollution caused by energy use is reduced, achieving a win-win situation of economic and environmental benefits. Through the demonstration effect, more enterprises and projects can be guided to adopt similar environmental protection construction plans to promote the green development of the entire industry.

[0047] Understandably, when determining the photovoltaic power generation area, it is necessary to fully consider the actual environmental information and construction drawing information to ensure that the photovoltaic power generation area is coordinated with the construction area and does not affect the construction progress and quality. At the same time, the layout, capacity, orientation, etc. of the photovoltaic power generation area can be reasonably planned to ensure the maximum efficiency of photovoltaic power generation. The excavated earth and stone need to be screened and processed to ensure that it meets the requirements of the photovoltaic power generation area construction. When using earth and stone to build the photovoltaic power generation area, necessary reinforcement and protection measures must be taken to ensure the stability and safety of photovoltaic power generation facilities. The selection of photovoltaic power generation facilities needs to be comprehensively considered based on local climatic conditions, light resources, and construction electricity demand. During the installation process, operations must be strictly carried out in accordance with relevant technical specifications and standards to ensure the safe, reliable and efficient operation of photovoltaic power generation facilities. During the operation of the photovoltaic power generation area, photovoltaic power generation facilities must be monitored and maintained regularly to ensure their normal operation and power generation efficiency. At the same time, it is necessary to monitor and evaluate the environmental impact of the photovoltaic power generation area, and take necessary environmental protection measures in a timely manner to ensure the green and sustainable development of the photovoltaic power generation area.

[0048] More specifically, the resources to be conserved in the construction area can be transferred, and protective measures can be implemented in the conservation area before dredging and filling operations are carried out, including: preserving the cultivated soil stripped from the topsoil in the construction area, and leveling and transforming the earth and stone from the dredging and filling operations. Among them, the cultivated soil stripped from the topsoil can be used for slope greening and covering, and at the same time, combined with land reclamation and land improvement measures, new cultivated land can be added. Focusing on the goal of "building a canal and a park", the earth and stone are comprehensively utilized to build a hub industrial park. These newly added cultivated lands not only solve the problem of earth and stone stacking, but also drive the prosperity of the rural economy, achieving a win-win situation of economic and ecological benefits.

[0049] At the same time, through the application of cultivated soil and earth and stone, various types of vegetation can be planted or transplanted on both sides of the construction area, providing habitats for wild animals and protecting the biodiversity of the canal area.

[0050] The excavated earth and stone can be used in a comprehensive manner for the following purposes: offshore land reclamation, green building materials, mine ecological restoration, park backfilling, temporary construction and engineering self-use, land reclamation, etc., to achieve intensive use of resources.

[0051] In this way, by preserving the cultivated soil stripped from the topsoil in the construction area and using it for slope greening and covering, the cultivated soil resources are reused and resource waste is avoided. The use of earth and stone for land leveling and transformation not only solves the problem of earth and stone stacking, but also realizes the addition of cultivated land, providing new impetus for rural economic development. Through the comprehensive utilization of earth and stone, such as land reclamation, green building materials, and mine ecological restoration, the intensive utilization of resources is achieved and environmental pollution is reduced. Planting or transplanting various types of vegetation on both sides of the construction area provides a habitat for wild animals and helps to protect the biodiversity of the canal area. By implementing protective measures in the conservation area, the damage to the ecological environment caused by construction activities is reduced and ecological restoration is promoted. The additional cultivated land not only solves the problem of earth and stone stacking, but also drives the prosperity of the rural economy and achieves the improvement of economic benefits. Through ecological restoration and greening measures, the ecological environment is improved, the regional ecological value is enhanced, and the ecological benefits are enhanced. The construction of hub industrial parks promotes regional economic development and forms a virtuous cycle of economic and ecological benefits.

[0052] Understandably, before construction begins, the topsoil in the construction area is stripped and properly preserved. During the stripping process, it is necessary to avoid damage to the soil structure and ensure soil quality. The preserved topsoil can be used for subsequent slope greening and covering, and can also be used in other areas where soil restoration is required. The use of earth and stone from dredging and filling operations for land leveling and transformation must be reasonably designed based on topography and land use planning. During land leveling, it is necessary to ensure the uniform distribution of earth and stone to avoid the formation of uneven terrain that affects land use. Through land consolidation measures, the leveled land is developed into newly added arable land, and it is necessary to ensure that the quality of the arable land meets the requirements of agricultural production. The newly added arable land can be used to grow crops, cash crops, etc., to improve land use efficiency and agricultural production benefits.

[0053] Planting or transplanting various types of vegetation on both sides of the construction area should be reasonably selected according to local climate conditions and ecological environment. During the vegetation planting process, attention should be paid to the survival rate and growth status of the vegetation to ensure that the vegetation can play an ecological role. By implementing protective measures in the conservation area, such as setting up fences and prohibiting hunting, the interference and damage of construction activities to wild animals can be reduced.

[0054] The excavated earth and stone need to be classified and processed according to different utilization directions. For example, land reclamation can be used for land reclamation in sea areas or lakes; green building materials can be used for the production of building materials; mine pit ecological restoration can be used for ecological restoration of abandoned mine land; park backfill can be used for land backfill during the construction of industrial parks; temporary construction and engineering self-use can be used for temporary facility construction and engineering self-use during the construction process; land reclamation can be used for the reclamation and reuse of abandoned land. In the process of comprehensive utilization of earth and stone, we must pay attention to resource conservation and environmental protection to avoid waste of resources and environmental pollution.

[0055] More specifically, maintenance and construction operations can be carried out within the conservation area, including: cleaning and maintenance of mangroves within the conservation area and / or pest control maintenance. A special mangrove protection team can be set up to conduct daily field patrols, regularly organize drone aerial photography, and closely monitor changes in the mangrove environment. In addition to implementing anti-pollution measures, mangroves can also be cleaned regularly to remove dirt attached to the roots, stems and leaves of mangroves. At the same time, mangrove pest control can also be carried out.

[0056] In this way, through pollution cleaning and pest control maintenance, the dirt and pests on the mangroves are effectively removed, the growth environment of the mangroves is improved, and the healthy growth of the mangroves is promoted. The combination of on-site patrols and drone aerial photography can timely discover and deal with abnormal conditions in the mangrove environment, effectively preventing the occurrence of ecological environmental damage events. As an important ecosystem, the healthy growth of mangroves helps to improve the biodiversity in the region and provide suitable habitats and food sources for wild animals. The implementation of maintenance operations helps to protect rare species such as mangroves and maintain ecological balance. Through the implementation of maintenance operations, the public's awareness of the importance of mangrove ecosystems can be strengthened and the public's environmental awareness can be enhanced. At the same time, maintenance operations can also be used as materials for popular science education, providing the public with an opportunity to understand the mangrove ecosystem.

[0057] Understandably, mangroves should be cleaned regularly to remove dirt attached to the roots, stems and leaves of mangroves, so as to keep them clean and healthy. Environmentally friendly cleaning agents and tools should be used during the cleaning process to avoid secondary pollution of mangroves. Cleaning operations should be reasonably arranged in combination with the growth cycle and seasonal changes of mangroves to avoid adverse effects on the growth of mangroves. Regular mangrove pest surveys should be conducted to understand the types, quantity and distribution of pests, so as to provide a scientific basis for pest control. According to the results of pest surveys, targeted pest control measures should be formulated, such as spraying biological pesticides and setting up natural enemy habitats. In the process of pest control, attention should be paid to ecological balance to avoid damage to the mangrove ecosystem.

[0058] More specifically, maintenance and construction operations can be carried out in the conservation area, including the construction of fishway projects in the conservation area. Specifically, a fishway project combining vertical slit fishways and eelways can be built to facilitate the migration of various fish. At the same time, fishways help the genetic exchange of fish in the area and have a positive significance for maintaining the stability of aquatic animals. More specifically, the fishway inlet can be set at the tailwater of the power station to attract fish using the flow rate.

[0059] In addition, fish breeding stations and ecological conservation areas can be set up along the project line.

[0060] In this way, the construction of a fishway project combining vertical slot fishways and eelways can effectively adapt to the migratory habits of different fish and provide them with safe and convenient passages. The establishment of fishway projects helps fish to exchange genes between different waters, enhances the genetic diversity and adaptability of fish populations, and has positive significance for maintaining the stability of aquatic animals.

[0061] Fishway projects can reduce damage to fish habitats and reduce the impact of water conservancy projects such as hydropower stations on aquatic ecosystems. The establishment of fish reproduction stations and ecological conservation areas can help restore and enhance the self-repair ability of aquatic ecosystems and maintain ecological balance. The implementation of fishway projects helps protect fish resources and prevent the reduction of fish populations and biodiversity caused by water conservancy projects. As an important part of aquatic ecosystems, the increase in the number and diversity of fish contributes to the stability and prosperity of the entire ecosystem. The construction and operation of fishway projects embody respect and protection for the natural environment and are in line with the concept of sustainable development. By protecting and restoring aquatic ecosystems, it helps to enhance the ecological value of the region and provide strong support for sustainable development industries such as ecotourism.

[0062] Understandably, the design of vertical slot fishways needs to consider the size, swimming ability and migratory habits of fish, ensuring that the parameters such as fishway width, height and flow rate meet the passage needs of fish. Eelways need to be specially designed to adapt to the migratory characteristics of eels, such as setting up gentle slopes and increasing water flow resistance. The fishway inlet should be located at the tailwater of the power station, using the flow rate to attract fish. At the same time, the connection method between the fishway inlet and the tailwater outlet of the power station needs to be considered to ensure that the fish can enter the fishway smoothly.

[0063] Fish breeding stations should generally be located near fishways to facilitate fish entry and reproduction. Fish breeding stations can be equipped with professional breeding equipment and personnel to carry out artificial breeding and seedling cultivation of fish. Fish breeding stations can also conduct fish ecology research to understand the living habits and reproduction patterns of fish and provide guidance for scientific breeding.

[0064] Ecological conservation areas can be selected near the upstream and downstream of fishways to provide fish with a suitable habitat and breeding environment. Aquatic plants can be planted in conservation areas to build wetland ecosystems and provide food and habitats for fish. Conservation areas can also set up areas where fishing and angling are prohibited to protect fish resources from being destroyed.

[0065] Compared with the prior art, the environmentally friendly dredging and filling method provided by the embodiment of the present invention can comprehensively evaluate the impact of construction on the surrounding environment by obtaining detailed actual environmental information of the area to be dredged and filled, so as to make adequate planning and preparation before construction. The construction area and the conservation area are clearly divided to ensure that construction activities will not directly damage or interfere with natural resources or ecological environments that need to be protected. The resources to be conserved in the construction area are transferred, and special protection measures are implemented in the conservation area, which effectively reduces the negative impact of construction activities on the ecology and protects biodiversity.

[0066] Through the above description of the implementation methods, the technicians in the relevant field can clearly understand that the present invention can be implemented by means of software and necessary general hardware, and of course can also be implemented by hardware, but in many cases the former is a better implementation method.
