A sand pump is a mechanical device used to extract sand from rivers, lakes, oceans, and other water bodies. It usually consists of a hull, sand pump, conveying pipeline, power system, etc.
The working principle of a sand pump is to suck sand from the bottom of the water into a pipeline and transport it to a designated location. The depth and output of sand pumping by the sand pumping boat depend on the power of the sand pumping pump and the diameter of the pipeline.
According to different work requirements and water conditions, sand suction boats can be divided into various types, such as self-propelled sand suction boats, non self-propelled sand suction boats, cutter suction sand suction boats, flushing suction sand suction boats, etc. Among them, the cutter suction sand pump is a common type, which can complete the excavation, transportation, and slurry treatment processes in one go, and has the advantages of high sand pumping efficiency and wide applicability.
When using a sand pump, the following points should be noted:
1. Comply with relevant laws and regulations: Before conducting sand pumping operations, it is necessary to understand the relevant local laws and regulations and ensure that the sand pumping operations comply with regulations.
2. Pay attention to safety: When operating the sand pumping boat, it is necessary to pay attention to safety to avoid accidents.
3. Environmental protection: Sand pumping operations may have a certain impact on the water environment, so corresponding environmental protection measures need to be taken, such as avoiding excessive sand pumping and reducing sediment leakage.
4. Maintenance: Regularly maintain the sand pumping boat to ensure its normal operation.
In short, sand dredgers are an important mechanical equipment that can be used in fields such as river dredging, port construction, and land reclamation. When using a sand pumping boat, it is necessary to comply with relevant laws and regulations, pay attention to safety, protect the environment, and regularly maintain it.
A cutter suction dredger is a dredging tool that uses a rotating cutter to loosen the soil on the riverbed or seabed, mixes it with cement to form mud, and then sucks the mud into the pump body through a suction pipe and sends it to the discharge area. It is mainly used for dredging in inland lake areas and coastal ports, suitable for excavating soil such as sand, sandy loam, and silt. During the construction of the cutter suction dredger, the dredging, transportation, and unloading processes can be completed continuously in one go, resulting in high production efficiency.
The main structure of a cutter suction dredger includes the hull, cutter, suction pipe, pump body, and discharge pipe. The cutter is a key component of a cutter suction dredger, usually installed at the bow or side of the ship. By rotating the cutter, the sediment at the bottom of the water is crushed and mixed with water to form mud. The suction pipe is used to suck mud into the pump body, which transports the mud to the discharge area through the discharge pipe.
The advantages of a cutter suction dredger include high construction efficiency, low operating costs, simple operation, and the ability to adapt to different types of sediment. However, it also has some limitations, such as difficulty in construction in high wind and wave areas, making it more suitable for working in inland rivers and lakes. Dredgers can excavate depths of 6-18 meters underwater and transport distances of up to 4-3000 meters.
The construction process of the cutter suction dredger is generally as follows:
1. Construction preparation: including the formulation of construction plans, measurement of construction area, equipment inspection and commissioning, etc.
2. Ship positioning: Using the DGPS positioning system, accurately locate the cutter suction dredger at the starting point of excavation in the construction area.
3. Set up side anchors: Based on the airflow situation, set up headwinds and headwinds anchors to stabilize the hull.
4. Lowering the knife bridge: Lower the knife bridge to the designated cutting position for excavation.
5. Transportation: Use a high-power centrifugal mud pump and discharge pipeline to transport the soil crushed by the cutting machine to the designated mud receiving area.
6. Mobile vessel position: According to construction needs, move the vessel to the next construction area by retracting and releasing anchor cables and adjusting the winch position.
When using sand dredgers for operations, the following measures can be taken to avoid environmental pollution:
1. Reasonable planning of work areas: Before carrying out sand pumping operations, the ecological environment of the work area should be fully evaluated, and important areas such as ecologically sensitive areas and fish spawning grounds should be avoided.
2. Control sand pumping volume: Avoid excessive sand pumping to reduce damage to riverbed structure and aquatic ecosystems. Strictly follow the relevant regulations and permitted sand pumping volume for operation.
3. Install sediment separation equipment: Install an efficient sediment separation device on the sand pumping boat to effectively separate the sediment and water pumped up, reducing the discharge of sediment with the water.
4. Adopting environmentally friendly sand pumping technology: for example, using low disturbance sand pumping methods to reduce agitation of water bodies and suspension of sediment.
5. Strengthen wastewater treatment: treat the wastewater generated during the operation process, remove suspended solids, oils and other pollutants, and discharge them after meeting the discharge standards.
6. Control homework time: Avoid sand pumping during critical ecological periods such as fish breeding and bird migration to reduce the impact on biodiversity.
7. Regular monitoring of water quality and substrate: Regularly monitor the water quality and substrate around the work area to promptly identify and solve potential environmental pollution problems.
8. Take anti leakage measures for the ship: ensure that the fuel, engine oil, and other liquids of the sand pumping vessel do not leak and pollute the water body.
9. Strengthen environmental awareness training for crew members: Improve their environmental awareness and ensure that they strictly comply with environmental regulations and operating procedures during the operation process.
