How to operate the concrete laser leveling machine

The operation method of the concrete laser leveling machine generally includes pre-operation preparation, equipment debugging, construction operation and post-operation processing. The following are the specific contents:

 

Pre-operation preparation

1. Site cleaning: Clear the debris and obstacles in the construction site to ensure that the ground is flat and there are no sharp objects to avoid affecting the operation of the equipment or damaging the tires and scrapers and other parts.
2. Equipment inspection: Conduct a comprehensive inspection of the equipment, including whether the connections of each component are firm, whether the electrical system and hydraulic system are normal, whether the laser transmitter and receiver can work normally, whether the water tank and oil tank levels are within the normal range, etc.
3. Material and tool preparation: Prepare the required concrete materials to ensure that their quality and performance meet the construction requirements. At the same time, prepare necessary auxiliary tools such as shovels, trowels, etc.
4. Staffing: Arrange at least one skilled operator and auxiliary construction personnel to be responsible for the loading and paving of concrete. Operators should be familiar with the operation methods and safety precautions of the equipment and wear appropriate personal protective equipment, such as safety helmets and safety shoes.

 

Equipment debugging

1. Laser system debugging: Turn on the laser transmitter and set the height and slope of the laser according to the construction requirements. Install the laser receiver on the corresponding position of the leveler, and adjust the height and angle of the receiver so that it can accurately receive the laser signal. Start the leveler and move the equipment to check the signal reception of the laser receiver to ensure that the signal is stable and accurate.
2. Scraper and vibration plate debugging: According to the paving thickness and construction requirements of the concrete, adjust the height and angle of the scraper to keep a suitable distance from the ground. Generally, the distance between the bottom of the scraper and the ground is slightly less than the design thickness of the concrete. At the same time, debug the vibration frequency and amplitude of the vibration plate. Usually, it is adjusted according to the slump and density requirements of the concrete. The vibration frequency and amplitude can be appropriately increased for concrete with a small slump.
3. Travel system debugging: Start the travel system and check whether the forward, backward, steering and other functions of the equipment are normal. Adjust the travel speed. According to the paving speed of the concrete and the construction progress requirements, select a suitable travel speed, generally within the range of 1-3 meters/minute.

 

Construction operation

1. Concrete loading and paving: Use concrete conveying equipment to transport concrete to the construction site, and auxiliary construction personnel will cooperate to evenly spread the concrete on the ground. The paving thickness should be slightly higher than the designed thickness, generally 5-10 cm higher, to compensate for the concrete sinking during the leveling process.
2. Leveling operation: The operator starts the concrete laser leveling machine and drives the equipment forward slowly. During the movement of the equipment, the scraper will scrape the raised concrete flat, and the vibration plate will vibrate and compact the concrete to make the concrete surface initially flat. During the leveling process, the operator should closely observe the signal changes of the laser receiver, and adjust the height of the scraper and vibration plate in time according to the signal indication to ensure that the flatness of the concrete surface meets the requirements.
3. Edge and corner processing: For corners that are difficult for the equipment to reach, auxiliary construction personnel need to use shovels, trowels and other tools for manual leveling to ensure the flatness and density of the entire construction surface.
4. Multiple leveling: For large-area concrete construction, multiple leveling operations may be required. After the first leveling, wait for the concrete surface to dry slightly, and then perform the second leveling to further improve the flatness and finish of the concrete surface.

 

Post-operation processing

1. Equipment cleaning: After the construction is completed, turn off the power supply of the equipment in time, use a high-pressure water gun or compressed air to thoroughly clean the equipment, and remove concrete residues, dust and other debris on the surface and components of the equipment. In particular, the scraper, vibrating plate, spiral feeder and other parts must be cleaned to prevent damage to the equipment after the concrete solidifies.
2. Component inspection and maintenance: Perform a comprehensive inspection of the equipment to check whether the components are damaged or loose, and repair and tighten them in time if there are any problems. At the same time, lubricate and maintain the parts that need lubrication in accordance with the equipment maintenance requirements, and add or replace lubricating oil, hydraulic oil, etc.
3. Storage equipment: Park the equipment at the designated storage location, ensure that the storage site is flat and dry, and avoid the equipment from being affected by natural factors such as rain and sun. If the equipment is not used for a long time, appropriate protective measures should be taken, such as covering with canvas.
