River dredging refers to the treatment of the river channel, blowing the sedimented silt at the bottom of the river into a turbid water shape, which flows away with the river water, so as to play a role in dredging.

Through mechanical equipment, the precipitated sludge is blown into a turbid water form, which gradually becomes soft, dry, and odorless over time, and these substances will eventually pollute the river water and affect the ecological environment. The following is an introduction to the specific content of river dredging for reference.

1. Cutter suction dredger dredging: first use bamboo pieces to pass through the place that needs to be cleaned, and then use an excavator to mine the earthwork; After placing the drill in the river channel, it is attached to the sleeve and cleaned up in sections along the pipeline.

2. Drain the sludge in the river: use a forklift or bulldozer to salvage the sludge (generally manually cleaned), and the sludge after dewatering treatment by the filter press can be directly transported. Which one is better to choose for river dredging?

River dredging is one of the important engineering measures to control water pollution. Through mechanical equipment, the sedimented silt at the bottom of the river is blown into turbid water and drained away with the river water, thus playing a role in dredging. Under normal circumstances, the workload of river dredging will be relatively large, and a lot of manpower and material resources are required to complete the task.

The following is an introduction to the dredging of the river

1. The excavation depth is about 30 meters, mainly according to the characteristics of the river and the local environmental conditions, and the specific construction methods are as follows: first, clean up the trees or garbage around the river embankment head, and use an excavator to push it into the distance; Secondly, the excavator was used to pull the solid waste material in the riverbed to the storage yard on the bank, so that it could naturally settle down to form a soil layer. Finally, the treated sludge is dried and used as a building material; Then set up cofferdams around the yard to block weeds and other materials; The air supply from the outside is then directed to the two edges of the yard, so that the nearby land gradually becomes a fertile environment.

2. The transportation distance is about 20 kilometers, and the transportation distance is short, which can be used for loading and unloading at the port terminal; If a ship or aircraft is used as a means of cargo, it is necessary to prepare the cargo in advance; In addition, for some harder items, such as iron train can also be easily lifted down and transported away, so that both are conducive to safety and facilitate the transportation process, but this mode has risk, and the cost is higher, and there is a certain threat to the health of the operator.

The siltation of rivers has increasingly affected the normal performance of various functions such as flood control, drainage, irrigation, and water supply, in order to restore the normal functions of rivers and promote rapid and sustainable economic and social development. River dredging and dredging projects often occur "digging wells" and "digging cellars" to clean out a large amount of sediment and achieve the purpose of purifying the environment. As a result, the river channel has become deeper and wider, the river water has become clearer, the water of the masses has become thicker and thicker, and the production conditions and living environment of the masses have been markedly improved.

(River dredging and silting).

River dredging is an important engineering measure to control rivers and lakes and keep water quality clean. Through mechanical equipment, the sedimented silt at the bottom of the river is blown into turbid water and drained away with the river water, thus playing a role in dredging.

Most of China's rivers are dredging by manual cleaning and mechanical unloading construction methods, so as to reduce the impact on the environment and promote the rapid and sustainable development of economy and society. Let me introduce you to the methods and precautions of river dredging!

1. Cutter suction dredger.

The cutter suction dredger uses the cutter excavator to scour the earthwork scraped to the shore by the silt at the forward speed along the riverbed under the action of gravity; When the sand and gravel are excavated with a bucket at the first working section from top to bottom, the gravel is first thrown off the riverbed and loaded into a transporter to pull it away, then it is stopped by a fence on the other side, and then lifted to a position where it is moored next to the dredger's side. This machine is suitable for open warehouses or for field operations; It is suitable for large-area topographic survey.

2. Drainage and irrigation pumps.

Drainage and irrigation pump is a device widely used in various types of waterway drainage systems, also known as pipeline drainage and irrigation pump, which is composed of various forms such as power-driven drainage and irrigation pump and water jet, which can realize the arbitrary discharge of sewage in the riverbed. It has the characteristics of simple structure, convenient operation and easy maintenance. Irrigation and drainage pumps can be equipped with different models and specifications according to user needs, which can not only meet different use needs but also be directly delivered to the designated place. The working principle of the drainage and irrigation pump is to generate a strong shock wave under the action of high-pressure water jet, such as a strong negative pressure to rupture and coalesce the suspended particles in the water to form a large block, and diffuse inside the solid phase to achieve the purpose of purification.

3. Vacuum suction pump.

Vacuum suction pump, also known as rotary vacuum sludge, is mainly to provide users with high-quality products and services with high efficiency. It can not only effectively remove pollutants from wastewater, but also improve production efficiency as a useful resource. At the same time, due to its unique design concept, the performance of this series of products has been greatly improved.

4. Yard leveling machine.

The overall layout and layout of the yard are compact, which can withstand a large number of loads, which is conducive to the installation of building materials and the rest of on-site personnel. Therefore, it is very important to build a storage yard. The silt layer is thick and unevenly distributed, which often makes it difficult to complete uniform planning. Therefore, it is necessary to conduct a detailed investigation and study of the environment around the river and formulate a reasonable dredging plan to ensure that the sludge removed will not cause secondary pollution to the surrounding ecological environment.

River dredging refers to the process of treating rivers, restoring water quality, and ensuring the safety of people's lives and property. Through mechanical equipment, the sedimented silt at the bottom of the river is blown into turbid water and drained away with the river water, thus playing a role in dredging.

How to deal with river silt?

1. Choose the appropriate sludge treatment technology.

The technology of sludge treatment mainly refers to the use of advanced technological processes to blow and stir the sedimented silt at the bottom of the river into turbid water, which flows away with the river water, and finally obtains a more ideal dredging effect.

How is river dredging cleared?

In order to restore the normal function of the river and promote the rapid and sustainable development of the economy and society, the river and lake improvement project is carried out. Through mechanical equipment, the sedimented silt at the bottom of the river is blown into turbid water and drained away with the river water, thus playing a role in dredging. The following is the relevant content I brought to you about how to clean up the river dredging for reference!

In order to ensure the safety and smooth development of the construction process, it is necessary to fully classify and select the relevant building materials and equipment. First of all, it is necessary to understand where there may be garbage dumping sites in the river and whether the garbage has peculiar smells. The second is whether cofferdams or ditch sealing measures can be set up during dredging; Finally, according to the actual situation, a reasonable safety protection distance table (such as ropes) should be formulated to prevent personnel from entering it and dangerous incidents occur; In addition, it is also necessary to pay attention to the construction of on-site drainage facilities to avoid rainwater splashing directly into the eyes or causing damage to the eyes; Finally, it is necessary to strengthen daily inspections, find problems in time and take corresponding preventive control measures to ensure the life and health of operators.

Due to the relatively developed river management in China and the lack of unified technical standards, it is necessary to pay more attention to the management and protection of rivers along the route and effectively protect the interests of the people. At the same time, it is also necessary to reasonably design dredging plans according to the characteristics of the river in different areas to minimize the impact on the surrounding environment and realize the principle of "one enterprise with multiple uses".

For enterprises engaged in river dredging activities, they should actively participate in environmental awareness training and scientific planning of construction processes, so that they can comply with relevant laws and regulations and standardize their operations. At the same time, we should establish and improve the corporate image signage, so that the public can see that their legitimate rights and interests are effectively safeguarded.

The importance of paying attention to quality in river dredging is to improve the environmental sanitation level in the river channel, and also to improve the living standards of residents on both sides of the riverbank. At the same time, it can also strengthen the maintenance of the embankment, regularly check whether the safety valve of the embankment is intact, and deal with it as soon as possible in case of failure. At the same time, it is also necessary to strengthen source control, strictly implement it in accordance with relevant national regulations, and complete the dredging task as soon as possible and produce results as soon as possible.

The promotion of river obstacle removal work has been strengthened, and in some special circumstances, a combination of arrest and capture can be implemented, and the sludge in the river can be excavated and landfilled through the form of grab dredger operation. This is not only conducive to reducing pollution, but also effectively improving navigation conditions, minimizing the harm to the living environment of local people, and achieving a sustainable development model.

River dredging generally refers to the treatment of river channels, which is a water conservancy project. Through mechanical equipment, the sedimented silt at the bottom of the river is blown into turbid water and drained away with the river water, thus playing a role in dredging.

China is now in a new round of environmental remediation climax, in order to adapt to this situation needs to carry out river dredging work. This paper briefly analyzes the problems and countermeasures encountered in the process of river dredging.

The first is to clean up weeds, garbage, and other waste near the site. After simple classification treatment, it can be turned into organic fertilizer, which can improve soil utilization, reduce agricultural losses, and also improve the ecological environment.

The second is to strengthen the safety protection of embankments to prevent floods. Through scientific planning and design, reasonable construction of cofferdams, storage and drainage channels, reasonable setting of warning signs and signs, to ensure the safety of the life and property of construction personnel. Finally, some pollution sources should be thoroughly cleaned to avoid secondary pollution from causing social concern and controversy again.

Dredging is one of the common tasks in urban management, in order to improve the efficiency of dredging and reduce the burden of labor, Baros has launched an efficient and intelligent dredging robot to help the city quickly clean up sludge and debris, and help the city to be cleaner and more livable. A large number of fish and their larval eggs and some small insects that are difficult to biodegrade have been removed from rivers and lakes; It can also be operated by manual excavation or submersible fine sand boats on the seabed, which will reduce the water content of the removed sludge and increase the difficulty and cost of the follow-up process; It is also possible to use the deep well injection method to mine the sludge as raw materials for production or industrial water, and then use it to transform it into useful products to achieve the purpose of environmental protection.

2. Apply lime. When using lime, care should be taken not to directly contact **, if there is burns, it should be rinsed with water in time. The sludge should be placed in a cool and dry place for a period of time, which is conducive to the absorption of nutrients by the roots of the plant, which is conducive to the normal growth of crops and will not produce peculiar smells.

3. Stack cement mortar. If there is no proper place to pile up enough concrete paving, it is easy to form a large amount of construction waste, which not only occupies land resources, but also causes the bearing capacity of the foundation to decline and lead to the rise of the groundwater level. Therefore, we can start from the following aspects for this phenomenon:

According to the nature of the sludge, a landfill in line with national standards can be constructed, which can not only reduce the environmental burden but also ensure long-term stable storage; It is also important to protect the surrounding vegetation and keep it out of direct sunlight as much as possible.

River dredging generally refers to the treatment of river channels, which is a water conservancy project. Through mechanical equipment, the sedimented silt at the bottom of the river is blown into turbid water and drained away with the river water, thus playing a role in dredging.

The river silt treatment methods are:

1. Physical method: the method of separating and diluting the silt at the bottom of the river by gravity. This method is simple and easy to implement, and is suitable for large areas and wide rivers and lakes. Because it is affected by environmental factors, it is easy to cause secondary pollution. Commonly used methods include pontoon cleaning method, high-pressure pump injection suction method, etc. This method requires a lot of manpower and material resources to operate, and it will produce a certain noise hazard. Moreover, this method is more costly, and it also has an impact on the quality of life of the surrounding residents.

2. Chemical method: The process of using chemical agents to dissolve and decompose harmful substances in sewage, such as using lime milk or other similar chemical reagents as neutralization reactors, and converting them into carbon dioxide and water is called chemical method. The chemical method is a method that uses chemical reactions to remove harmful substances from water. Commonly used are ferrous sulfate, ferric chloride, sodium tripolyphosphate and other alkaline compounds. These substances can reduce the impact on human health by adding appropriate chemicals to turn waste into harmless substances. At the same time, it also has environmental benefits, which can effectively protect the ecological environment and purify the air.

3. Biological method: use the metabolic function of microorganisms to discharge dirt from the body to achieve the purpose of a clean environment. This technology is widely used in soil improvement in industrial and mining enterprises, breeding farms, and landfills, and has been widely used. In practical application, the advantages of biological methods are mainly manifested in strong adaptability (up to more than 90%) and low energy consumption (only about 30 minutes can be completed). However, this method also has some limitations, such as the problem that organic matter cannot be eliminated in time; At the same time, there are safety risks. Therefore, if you want to solve this problem better, it is best to find a professional or a third-party organization, because only in this way can you avoid such things more effectively.
