  In various engineering construction projects, the rational selection and combination of engineering equipment is of vital importance for enhancing construction efficiency, ensuring project quality, and controlling costs. Different engineering scenarios require specific equipment combinations to meet construction needs. The following will introduce several common engineering equipment combinations, their applicable scenarios, and operational and maintenance precautions.

  Equipment Combination for Earthwork Construction: Excavator + Dump Truck

  • Practical Applications

  This combination is widely used in various earthwork excavation projects, such as construction pit excavation, road subgrade excavation, and mine soil stripping. The excavator is responsible for digging out the soil from the original location, while the dump truck transports the excavated soil to the designated waste dump or filling area. In large infrastructure projects, such as highways, railways, airports, etc., this equipment combination can efficiently complete a large amount of earthwork operations.

  • Operating Precautions

  Excavator Operation: Operators must be familiar with the performance and operating procedures of the excavator. They should choose the appropriate excavation method and bucket capacity based on the soil conditions. During the excavation process, they should control the depth and angle of excavation to avoid over-digging or under-digging. At the same time, they should constantly observe the surrounding environment to ensure safety and prevent the excavator from colliding with surrounding obstacles.

  Self-Loader Operation: Drivers must strictly follow traffic rules and instructions from the construction site. They should control the vehicle speed, especially when loading and unloading soil, to ensure the vehicle is stable and prevent it from skidding. During transportation, they should plan the driving route reasonably to avoid sudden braking and sharp turns to reduce soil spillage and damage to the vehicle.

  • Maintenance Precautions

  Excavator Maintenance: Regularly inspect the hydraulic system, engine, transmission system and other key components of the excavator. Replace hydraulic oil, engine oil, filters and other wear-prone parts in a timely manner. Keep the excavator clean and regularly clean the radiator to prevent dust and debris from blocking and affecting the cooling effect. At the same time, check and maintain the walking parts such as the tracks and chains of the excavator to ensure their normal operation.

  Self-Loader Maintenance: Regularly inspect the braking system, tires, transmission shaft, etc. of the vehicle to ensure good braking performance and normal tire pressure. Perform regular maintenance on the engine of the vehicle, replace engine oil, oil filters, air filters, etc., to ensure the normal operation of the engine. In addition, check the sealing of the cargo compartment to prevent soil leakage.

  Concrete Engineering Equipment Combination: Concrete Mixing Station + Concrete Mixing Transport Vehicle + Concrete Pump Truck

  Practical Applications

  This combination is mainly used for concrete construction in large-scale construction projects, such as high-rise buildings, bridges, tunnels, etc. The concrete mixing station is responsible for centralized production of concrete. The concrete mixing transport vehicle transports the mixed concrete to the construction site. The concrete pump truck pumps the concrete to the pouring location. This combination can achieve efficient production and transportation of concrete, ensuring the quality and progress of the construction.

  Operating Precautions

  Operation of Concrete Mixing Station: Operators must strictly follow the mix ratio when weighing and mixing raw materials to ensure that the quality of the concrete meets the design requirements. During the mixing process, they should closely monitor the operation status of the mixing equipment and promptly identify and address any abnormalities. At the same time, they should ensure the cleanliness of the mixing station to prevent contamination of the raw materials.

  Operation of Concrete Mixing Transport Vehicle: Drivers should keep the vehicle stable during transportation to avoid severe jolts that cause concrete to separate. Before loading, they should drain the water from the mixing drum to prevent any impact on the quality of the concrete. After arriving at the construction site, they should quickly and accurately connect with the concrete pump truck to ensure that the concrete can be pumped in time.

  Operation of Concrete Pump Truck: Operators should reasonably arrange the position and pipelines of the pump truck according to the site conditions to ensure smooth pumping. During the pumping process, they should control the pumping speed and pressure to avoid pipeline blockages. At the same time, they should regularly inspect the hydraulic system, boom, and other components of the pump truck to ensure their safety and reliability.

  Maintenance Precautions

  Maintenance of Concrete Mixing Station: Regularly inspect and maintain the mixing machine, batching machine, conveyor belt, etc. of the mixing station, and clean the residual concrete in the mixing machine to prevent clumping. Check the electrical system's lines and components to ensure normal operation. Regularly calibrate the metering system of the mixing station to ensure accurate batching.

  Maintenance of Concrete Mixing Transport Vehicle: Regularly inspect the mixing drum, reducer, hydraulic system, etc. of the vehicle, and replace worn parts. When cleaning the mixing drum, use appropriate cleaning agents to avoid corrosion of the mixing drum. At the same time, check the vehicle's tires, brakes, etc. to ensure safe driving.

  Maintenance of Concrete Pump Truck: Regularly inspect and maintain the boom, hydraulic cylinder, conveying pipeline, etc. of the pump truck, and replace seals and wear parts. Check the electrical system and control system of the pump truck to ensure their sensitivity and reliability. After each pumping operation, promptly clean the pump truck and conveying pipeline to prevent concrete from solidifying and blocking.

  Equipment Combination for Pile Foundation Construction: Rotary Drilling Rig + Track Crane + Concrete Pipe

  Practical Applications

  Suitable for various pile foundation construction projects, such as building piles, bridge piles, and port and wharf piles. The rotary drilling rig is used for drilling and forming holes, the track crane is responsible for lifting the steel cage and concrete pipes and other materials, and the concrete pipe is used for pouring concrete. This combination can efficiently complete the processes of pile foundation drilling, steel cage installation, and concrete pouring.

  Operating Instructions

  Rotary Drilling Machine Operation: Operators should select the appropriate drill bit and drilling parameters based on the geological conditions, and control the drilling speed and pressure. During the drilling process, they should closely monitor the operation status of the drilling machine and the conditions inside the hole, and promptly address issues such as stuck drill and hole collapse. At the same time, they should ensure the positioning and fixation of the drilling machine to guarantee the verticality and position accuracy of the hole.

  Track Crane Operation: Drivers should operate strictly in accordance with the lifting operation procedures to ensure a safe and reliable lifting process. When lifting steel bars and concrete conduits, they should select appropriate lifting points and lifting tools to avoid slippage and tilting. At the same time, they should pay attention to observing the surrounding environment to prevent collisions with surrounding facilities and personnel.

  Concrete Conduit Operation: When installing and dismantling the concrete conduit, ensure a tight connection of the conduit to prevent leakage. During the concrete pouring process, control the depth of the conduit burial and the lifting speed to avoid quality issues such as broken piles.
