Requirements and Measures for Safety Construction of Concrete Cutting

    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.

  In recent years, not only the construction industry continues to grow, the price of labor is also rising, and the construction has put forward higher requirements for the quality of construction, so the laser leveling machine is rapidly popular in the construction, then, the use of laser leveling machine for concrete floor leveling construction compared with manual construction, what are the advantages? The following article makes some introductions for you, I hope you can be interested. 1, save labor: each laser leveling machine can save 7-8 people The use of manual concrete leveling construction, each team is composed of at least 15 people, the use of laser leveling machine for concrete leveling construction, each team is equipped with 8 people, according to the price of about 200-300 yuan per person per day to calculate, one equipment can save labor input of about 2000-3000 yuan. 2, improve the construction efficiency, shorten the construction period The laser leveling machine is used for construction, and the width of the leveling head is 2.5-3 meters. According to the normal driving speed of construction, 300-500 square meters can be constructed per hour, and 3000-5000 square meters can be constructed per shift. The use of manual construction, each shift is completed within 800 square meters, the same shift, the machine construction efficiency is about 5 times the manual construction efficiency, so it will greatly shorten the construction period, and do not need to repeatedly support the mold, saving construction costs. 3, the use of laser leveling machine leveling, greatly improve the quality of floor construction The original manual floor construction, the use of vibration pump, point vibration, often appear empty drum, cracking, leveling inaccurate problems, the construction quality is far lower than the machine construction quality. The use of laser leveling machine for concrete floor construction, the use of laser control leveling level, the use of motor 3000 times per minute, each 2000N (200KG) exciting force surface extrusion, greatly improve the density of concrete, enhance the construction quality. 1, look at the model; Mainly according to the construction site and area to choose the appropriate concrete laser levelling machine. 2, look at the use of the machine effect; The high quality concrete laser levelling machine has stable effect. 3, leveling speed; High quality laser levelers are fast. 4, leveling accuracy requirements; High quality concrete laser levelling machine leveling accuracy is higher. 5, the technical strength of laser leveling machine manufacturers directly affects the quality of equipment. 6, look at security; In the selection of concrete laser levelling machine, but also fully consider the braking performance of the concrete laser levelling machine, operation safety.
