What are the specific advantages of using concrete laser leveling machines in the construction industry?

  1. Construction preparation: – Equipment debugging: Perform a comprehensive inspection and debugging of the laser leveling machine to ensure its good performance and normal operation. – Benchmark setting: Make at least 2 fixed benchmark leveling points based on the original leveling point to control the floor elevation. – Site cleaning: Remove debris, garbage, etc. in the construction area to ensure that the base is flat and clean. – Material preparation: Prepare the required concrete, hardened materials, etc., and ensure that their quality meets the requirements. 2. Concrete paving: – Within the effective range of the telescopic arm of the laser leveling machine, first spread the concrete roughly by hand, and the thickness is slightly higher than the design elevation. – Then the laser leveling machine completes the vibration, compaction, and leveling work at one time to ensure that the concrete surface is flat and uniform. 3. Spreading of hardened materials: – When the concrete is initially set (a 3-5mm mark is left by the finger pressure test), first spread 2/3 of the hardened aggregate (non-metallic aggregate or metal aggregate and alloy aggregate) evenly in the vertical and horizontal directions to allow the material to fully absorb the moisture in the concrete. – Use a smoothing machine to smooth it, and then spread the remaining 1/3 of the hardened aggregate evenly, smooth it several times and then smooth it. The corners should be smoothed and smoothed with a manual trowel. 4. Maintenance and cutting of expansion joints: – After the construction is completed, the curing agent (water plus film, wax, sealing curing agent) can be used for curing, and the curing time should not be less than 7 days. – Cutting should be carried out at the earliest time while ensuring that the cutting does not burst the edge. Generally, the cutting should be completed 1-3 days after completion depending on the weather conditions and the concrete conditions at the time to prevent irregular cracking. The spacing of the cutting joints is determined according to the distance between the workshop columns, and it is preferably no more than 6m. The cutting line should be uniformly marked to ensure that the cutting joints are neat and straight, and the cutting depth should be at least 1/3 of the thickness of the concrete base. 5. Flatness test: – Use f-meter or measuring equipment of the same level to test the flatness to ensure that the flatness of the floor meets the requirements. – Repair the uneven areas detected in time. 6. Seam filling: – Before using the floor, fill the cut seams with seam filling glue to prevent debris from entering the seams and affecting the service life of the floor. The use of laser leveling machine for floor construction can greatly improve the construction efficiency and quality, reduce manual errors, and make the floor flatter and smoother. During the construction process, the operation should be carried out strictly in accordance with the construction process requirements to ensure construction safety and quality.  

The laser leveling machine is a kind of equipment that takes the laser emitted by the transmitter as the reference plane, and controls the leveling head in real time through the laser receiver on the laser leveling machine, so as to achieve high-precision and rapid leveling of concrete. It is indeed a time-saving and labor-saving way to use a concrete laser leveling machine to pave the ground. It is not only fast and effective, but also can save labor to the greatest extent. After the equipment is started, it will level itself according to the height of the ground or after manual leveling. For compaction, both methods can be applied. Main construction process: Civil engineering formwork support (bottom formwork) → steel bar tie-up → concrete pouring and laser leveling device elevation control → laser leveling machine for concrete leveling → professional technicians use scraper bars to level accurately → single-disc troweling machine to lift slurry and smooth → Professionals use scraper bars to accurately level → professional operation of double-disc driving trowel → surface finish → finished product protection 1. Civil engineering formwork (bottom formwork): Civil engineering formwork support (bottom formwork) is strictly controlled in elevation as in normal drawing design and construction specification acceptance standards, and the scaffolding is firmly supported. It should be noted that the "clear water concrete" building (ground) Surface and concrete pouring shall be constructed at the same time. In order to facilitate mechanical construction, there shall be no formwork or supporting elements higher than the building (ground) level, except for the reserved and pre-embedded levels. 2. Reinforcement tie-up: Because the surface layer is a building (ground) surface formed at one time by using the protective layer of reinforced concrete, the reinforcement must ensure that the concrete protective layer is sufficient, and no reinforcement, stirrups or weldments are allowed to be placed The concrete pouring surface layer is exposed, causing the machine to hit the steel bar, which not only destroys the machine but also destroys the surface layer of the building (ground). 3. Laser leveling instrument controls concrete pouring: set the elevation on the column reinforcement before concrete pouring, and lead the accurate elevation to the laser leveling instrument control system, and the concrete pouring personnel will control the elevation to be 5 times higher than the design elevation when scraping – Within the range of 10mm, lay a solid foundation for the leveling of the next laser leveling machine. 4. VANSE laser leveling machine leveling: In the case of accurate elevation setting by professional technicians, mechanical operators will accurately level the concrete surface under the control of the laser sweeper, and VANSE leveling machine will automatically level the surface The machine is calibrated and controlled to ensure the accuracy of the entire plane. 5. Leveling by professionals: This process is to re-measure the puddles with a laser sweeper when the bleeding of the concrete pouring surface is completed, fill the puddles with concrete, and use a scraper bar to rotate the opposite layer 360° to achieve a comprehensive level. Control the flatness and smooth the edge details of the column root formwork, and use the laser sweeper to repeatedly detect until the requirements are met. 6. Single-disk troweling machine for smoothing and lifting slurry: while the concrete is poured in an orderly manner according to the specifications, the concrete poured earlier will reach the initial setting earlier by using the time difference of the concrete construction. 2-3mm footprint), it is convenient to use single-disc troweling machine and troweling disc to perform cross-breaking troweling to ensure the smooth control of the mechanical operation process. facebook linkedin pinterest twitter whatsapp youtube instagram

    The long-term storage of the power trowel machine during the off-season of construction or during project intervals (usually referring to more than one month) is of vital importance. Proper storage and maintenance can greatly prevent equipment from rusting, aging and being damaged, ensuring that its performance remains as good as new when it is used again and extending its service life. The following is the standard "seven-step method" for the long-term storage of a power trowel. Please be sure to follow the sequence. This is the foundation of all steps and must never be stored with cement slurry on the machine. High-pressure flushing: Use a high-pressure water gun or a large amount of clean water to thoroughly rinse all parts of the machine body, blades, chassis, walking wheels, etc., and remove all cement, mortar, and mud lumps. Pay special attention to cleaning the connection area of the blade, the lifting screw and the area around the bearing sealing ring. Detail cleaning: Use tools such as scrapers and wire brushes to remove stubborn lumps. Comprehensive inspection: During the cleaning process, check whether the blades are worn or deformed, whether the screws and nuts are loose, whether the machine body is cracked, and whether the cables/oil pipes are damaged. Record the problems to facilitate subsequent maintenance. Move the machine to a well-ventilated, dry and rain-free indoor storage point. Dry/blow dry all surface moisture with a dry cloth or compressed air, especially: Exposed metal parts (lifting screw, adjusting rod). Blade. Engine surface. All oil injectors and gaps. Make sure that the inside and outside of the machine are completely dry, with no signs of dampness at all. Drain the old grease and add new grease: Use a grease gun to inject an adequate amount of new grease into all grease nozzles (spindle of the cutter head, bearings of the traveling wheels, steering mechanism, etc.) until all the old grease that may contain water is completely squeezed out. This can expel moisture and form a protective film inside. Apply anti-rust oil to key areas: Apply a layer of anti-rust oil or grease to all exposed metal surfaces prone to rust (non-friction contact surfaces). Key points include: Lifting screw and thread: Thickly coated with grease. Blade: Apply a thin layer of anti-rust oil to both sides (wipe it off before reuse). Chassis metal frame. Exposed bolts and nuts. Engine maintenance (for gasoline/diesel engines) : Change the engine oil: Drain the old oil when the engine is hot and add new oil to the specified mark. Fuel system treatment (crucial!)" : Option A (Recommended) : Completely drain the fuel from the fuel tank. Then start the engine and let it shut down naturally to deplete the residual fuel in the carburetor or fuel lines. Option B: If it is impossible to empty the fuel tank, fill it up with fuel and add fuel stabilizer. Then run the engine for 5 to 10 minutes to allow the stabilizer to circulate throughout the fuel line. This can prevent the fuel from gelatinizing and clogging the carburetor and fuel injector. Spark plug/fuel injector: Remove the spark plug, inject a small amount (about 10-15ml) of engine oil into the cylinder, manually and slowly pull the start rope several times to coat the cylinder wall with the engine oil, and then reinstall the spark plug (without connecting the high-voltage wire). Disconnect the battery: If the machine has power to start the battery, the negative cable should be disconnected. Remove the battery, store it in a cool and dry place, and perform a charge maintenance every 1 to 2 months. Protect the circuit: Wrap the exposed circuit joints with waterproof tape. Air filter: Remove the air filter, clean or replace it. Stuff a clean cloth into the air intake to prevent dust from entering. Tire: Lift the machine up to lift the tire off the ground to prevent the tread from being deformed and aged due to long-term single-point pressure. If it cannot be lifted, make sure the tire pressure is sufficient and move the position regularly. Blade: The blade can be removed. After cleaning, apply anti-rust oil separately and store it. Or at least ensure that rust prevention measures have been taken on the machine. Ideal environment: In a dry, cool and well-ventilated warehouse or shed. Avoid outdoor storage. Stay away from corrosion: Keep away from fertilizers, chemicals and damp ground. Stable placement: Place the machine on a flat ground and level it with wooden blocks if necessary. Cover: Use a breathable dust cover (such as a canvas cover) to cover the entire machine. It is strictly prohibited to directly wrap with completely impermeable plastic sheeting, otherwise water vapor will condense inside, causing severe rust. Marking: Hang a label that reads "Maintained and ready for storage" in a prominent position, and indicate the storage date and the date when the next inspection is required. Storage period: Every 1-2 months, check the machine for any abnormalities (such as tire pressure, the integrity of the covering, and whether there is any rat damage or wire biting), and recharge the battery. Before reactivation (very important!)" : Remove the coverings and check the overall condition. Check whether the grease in all parts has hardened and replenish or replace it if necessary. Reinstall the battery (if it has been removed) and connect it firmly. Remove the blockage at the air intake and reinstall the air filter. Wipe off the excess anti-rust oil from the key friction areas (such as the contact surface between the blade and the ground). Check the fuel and engine oil according to the normal start-up procedure, and then start the machine. First, run it at low speed without load for a few minutes to allow all components to lubricate and circulate. Only after there are no abnormal sounds can it be put into construction. Cleanliness is the prerequisite: no cement residue. Drying is fundamental: eliminate moisture. Lubrication and rust prevention are key: putting on a "protective suit" for metals. The fuel system needs to be properly handled: to prevent clogging. It's better to store off the ground: protect the tires. Regular inspections are indispensable: dynamic management. By following the above methods, your power trowel machine can quickly regain its "combat effectiveness" even after being idle for several months, effectively avoiding problems such as difficult startup, component jamming, and rust damage, truly achieving "always on standby, reliable and durable".   Note: The parameters provided in this document are for reference only and are not mandatory.
