Can Good Maintenance Habits Really Prolong The Service Life Of Laser levelings?
Can good maintenance habits really prolong the service life of laser levelings? Laser leveling machine is a great helper for leveling machinery in construction, but road builders can always feel that after several years of use, the equipment is far from being as flexible and convenient as before. What is the reason for this? Many users only know the surface and don't know the reason, so they can only procrastinate and procrastinate. When they use it next time, they will regret it. During the use of the laser leveling machine, due to the different working intensity, there may be some small faults after use. At this time, road builders should pay attention to it. After use, it is necessary to properly do some daily maintenance for the machine. This can prolong the service life of the machine equipment. 1.Check the connection and fastening of the parts of the laser leveling machine, whether the connecting bolts are loose or broken, and tighten or replace them if necessary. Check for leaks and eliminate leaks in various parts in time. Pay attention to the quantity of engine oil, fuel, coolant and hydraulic oil, and add new oil to the scale indicated on the oil mark as required. Whether there is proper amount of grease in the centralized lubrication device. 2.Be careful not to work under the maximum load that the machine can bear, and use the machine within your ability. As a laser leveling machine manager, when appointing an operator, the laser leveling machine random data and operation manual should be handed over to the operator, so that they can normally grasp the mechanical properties and operating procedures, and should not arbitrarily hand over the relevant information Buckle it down. 3.It is necessary to ensure the uniform addition and subtraction of the mechanical load as far as possible, so that the machinery is in a relatively gentle load change. Specifically, it is necessary to increase and decrease the throttle more evenly to prevent the engine and working devices from fluctuating greatly. 4.There will be a lot of dust and mud on the laser leveling machine after construction. First, wipe off the dust on the laser leveling machine, and wipe off the dirt and oil stains with tissue paper or cotton cloth. 5.If the laser signal is lost during the construction of the laser leveling machine, the machine needs to be restarted, and the interval should be more than ten seconds. 6.If there are too many stains, you can use a soft cloth to soak in water diluted with a neutral detergent, and then wring it out to clean it. The manufacturer of Wanshi laser leveling machine reminds everyone not to use volatile oil, thinner, gasoline and other chemicals to clean and wipe. . Developing a good habit of operating the laser leveling machine will be of great help to the construction and storage of the laser leveling machine in the future. This will not only improve the work efficiency, but also extend the service life of the machine to a certain extent .

Tell you how effective the concrete laser leveling machine is!
Tell you how effective the concrete laser leveling machine is! Many consumers are still hesitating whether they should buy a concrete laser leveling machine, because they have no concept of the construction effect of the equipment. Today we will introduce the use effect of the equipment. First of all, the biggest feature of this equipment is that it is fast, and the time-consuming is 1/10 of manual work, which is enough to make many construction teams excited; secondly, it is flat, and the ground level error after paving is small , is almost negligible. 1. Requirements for concrete and formwork ① Concrete: Concrete must be produced, conveyed or pumped to the flooring site by a commercial concrete production plant. ② Concrete specifications: C25~C30 concrete, the strength of which is not less than 25MPa in 28 days, according to the design requirements. ③ Water-cement ratio: N o more than 0.5, no water can be added during the feeding process. ④ Cement: Use ordinary Portland cement with a grade of not less than 42.5. ⑤ Aggregate: Well-graded aggregate should be used. Crushed granite or pebbles are used as coarse aggregate, and the maximum diameter is not more than 25mm. The fine aggregate is clean river sand with a fineness modulus of 2.4-2.7. ⑥ Concrete mix ratio: The amount of cement is not less than 350Kg/m3. In order to avoid surface quality problems, the sand rate should be controlled at 35% to 40%. ⑦ Concrete slump: 14±2cm, maximum 16cm. ⑧ Setting time: The initial setting time should be controlled within 3-5 hours. In order to avoid the excessive deviation of the surface elevation affecting the joints, the formwork should be steel formwork. The height of the formwork should be controlled within +0 and -2mm, and the steel formwork should be within 1-1.2 meters from the surrounding walls. 2. Construction cooperation requirements ① The concrete feeding speed should be determined according to the ground thickness and pouring area to determine the minimum hourly feeding speed. For a floor with a thickness of 200 mm, if the width of one-time pouring reaches 40 meters, the minimum feeding speed should reach 40 cubic meters per hour, otherwise there will be cold joint problems, which will affect the quality of ground construction. ② Manually coordinate the concrete sent to the platform, and workers need to remove it as soon as possible and roughly level it. In addition, the areas around the formwork, walls, columns, trenches, equipment foundations, floor drains or around pipelines that cannot be leveled require manual cooperation for local leveling. Generally, 3-4 workers are required to cooperate with the construction (provided by Party A). ③ Other precautions In order to ensure the flatness of the ground, attention should be paid to: 1) The slump of concrete sent to the platform must be consistent each time. 2) Ensure that the concrete feeding speed reaches 40 cubic meters per hour or above, and the initial setting time of each batch of concrete must be consistent. 3) Ensure that the formwork elevation is accurate and cannot be disturbed during construction. 4) Environmental cooperation. The concrete floor that has just been constructed cannot be exposed to sunlight, wind, rain, etc. that are unfavorable to concrete health. ④ Other requirements: A. In order to avoid random cracks in the floor, the cutting time of shrinkage joints should be carried out as early as possible (within 24 hours). B. At the same time as the construction of the laser leveling machine, there should be no electric welding machines on site, and no reflective objects (such as glass windows). C. The foundation must reach a certain hardness to ensure that the laser leveling machine does not collapse when working on the ground. D. The height of the ground in the factory building shall be calibrated by Party A, and the points must be evenly distributed, and there must be no error in the levelness. E. Pouring concrete must be operated according to the requirements of Party B's technicians.

Why does the road appear uneven?Is there any chance of getting better with laser leveling?
Due to the limitation of construction technology, the road surface is uneven in many cases, and the vehicle cannot maintain a very good stability during driving, and it may cause ruts after repeated rolling, which is equivalent to being stuck in a car. vicious circle. Wouldn't it be better to use concrete laser leveling? Nowadays, many roads are uneven, and there are many reasons. Now I will introduce the reasons for uneven roads: 1. The unevenness of the base layer affects the flatness of the road surface, resulting in uneven paving thickness, and the control of the base layer construction is not strict. Some even use bulldozers and graders to lay the base layer. The construction quality and flatness are difficult to control. 2. The influence of road paving machinery and technology on the smoothness: A. Improper selection of paver structure parameters, resulting in uneven paving thickness and waves; B. Improper control of the base line of the paver, resulting in waves; C. Improper operation of the paver causes uneven paving speed and frequent starting, resulting in rough and uneven surface layers; D. When a slipform paver is used for the concrete pavement, it is affected by the paver itself, control datum line and operation. 3. The influence of the quality of surface paving materials on the flatness: A. The ratio of asphalt pavement materials, mixing, oil temperature and shutdown due to material failure; B. Raw materials, proportioning and stoppage of materials for concrete pavement. 4. Effect of rolling on flatness: A. The use of low-frequency, high-amplitude road rollers will cause jumping and tamping phenomena, and excessive initial tonnage will cause pushing deformation; B. Uneven rolling speed, sudden braking, sudden start, random parking and U-turn, parking on the rolled and formed road without turning off the vibration device will cause road congestion, and stopping on the uncooled road will cause sunken; C. Improper rolling route, if you don’t pay attention to wrong wheel rolling, turning back at the same cross section every time will cause uneven road surface; D. The number of times of rolling is not enough, the compaction is not enough, and ruts are easy to form after opening to traffic. The leveling mechanism of the laser leveling machine is driven by hydraulic pressure, cooperates with the laser system and the computer control system to complete the leveling work while automatically leveling, and the work efficiency is extremely high. The laser transmitter used to control the ground level is arranged independently, and the level of the ground will not produce cumulative errors. Compared with the traditional method, the flatness of the super-large area is as easy to control, and at the same time, the construction joints and formwork usage of the floor are greatly reduced. Fast construction speed: use laser leveling machine and other equipment to construct concrete slabs, which improves the work efficiency by 3 times and saves 30% compared with the traditional beam vibrator method. It can complete 2000 square meters per day on average. It is especially suitable for simple shapes and large-scale operations. pavement construction. High degree of automation and low labor intensity: the use of laser leveling machines and other equipment changes heavy manual labor into mechanical paving, vibrating, leveling, slurry extraction, and surface plastering, reducing the number of operators by 30% and reducing labor intensity at the same time. High economic benefit: the application of laser leveling machine and other equipment saves the cost by 2-3 yuan/㎡ compared with the traditional process, with fewer joints and lower maintenance costs in the later period, so that the economic benefit is significantly improved. Advanced equipment such as laser leveling machines are especially suitable for projects such as docks, storage yards, expressways, airports, large squares, parking lots, and municipal roads that have relatively simple shapes, large amounts of action, and high construction quality requirements.

How to maintain concrete floors in different seasons?
HOW TO MAINTAIN CONCRETE FLOORS IN DIFFERENT SEASONS? -VANSE Machinery The current concrete floor is compacted with a concrete laser leveling machine, and there is almost no error. Concrete technology is becoming more and more important. Concrete has developed from the initial low-strength grade and ordinary concrete to today's high-strength grade and high performance. Sometimes the maintenance of concrete is often ignored in engineering construction, causing the surface of the concrete to shrink. , cracking, peeling and other phenomena, in order to make the concrete floor more sustainable and long-term use, it is necessary to pay special attention to the concrete curing method during construction. Different environments have different maintenance methods: During the high temperature and dry season, the moisture in concrete is easy to lose, so the following measures should be actively taken: 1. Cooling measures must be taken during construction, such as choosing to pour at night to avoid direct sunlight, and adjusting the concrete ratio in time. 2. At the same time, it must be noted that the temperature of the concrete formwork must be cooled, because if the temperature of the formwork is too high, the surface of the concrete will lose moisture quickly after pouring, resulting in defects such as sanding on the concrete surface. The maintenance of concrete in this season requires a lot of water, especially for the parts that are not easy to maintain, such as columns, cover beams, and beam webs, they should be tightly wrapped with geotextiles and sprinkled regularly. The surface of the concrete is always in a humid environment. In the early stage of curing, the concrete surface is sometimes dry and sometimes wet, because the strength of concrete that is sometimes dry and sometimes wet is easy to reduce, and it is easy to produce shrinkage cracks. Therefore, within 7 days of concrete pouring, it is necessary to prevent water evaporation and keep the concrete surface moist. In short, the focus of concrete maintenance in this season is moisturizing. If measures such as moisturizing and cooling are done well, problems such as early setting of concrete, plastic cracks, reduction of concrete strength and durability caused by high temperature will not appear. In the cold season when the temperature is lower than 5°C, the following measures should be taken for the maintenance of concrete: 1. After demoulding, cover and maintain the insulation. 2. The use of steam curing. 3. Improve the thermal insulation performance of the formwork. Most of the steel formwork used in bridge construction has good thermal conductivity and is easy to lose temperature. Therefore, insulation materials such as straw curtains should be wrapped outside the formwork or measures such as thickened formwork and double-layer formwork should be used. 4. Increase the mixing temperature of concrete. First of all, the heating treatment of the mixing water can be considered, and the aggregate can also be considered to be heated. The purpose is to ensure the initial cement hydration temperature and improve the early strength of the concrete. If the maintenance of concrete in the early cold period takes the above measures actively, the concrete will be prevented from freezing due to low temperature. After the concrete is frozen, its hydration will stop. After the temperature rises, although it can continue, the surface of the concrete has changed. Crisp, lose strength, and even larger cracks appear. Therefore, it is necessary to especially strengthen the early insulation and maintenance of concrete, and it must not be frozen before the concrete strength reaches 50% of the design strength.

Its maintenance can greatly improve the life of the machine and save costs. Laser leveling machine maintenance method/step Fuselage cleaning: When cleaning the surface of the machine, first check whether there is any depression or leakage in the fuel tank, oil pipes, joints, etc., and check whether the fixing screws of the fuel tank bracket are tightened before cleaning. Prevent rust: In the daily maintenance of the laser leveling machine, butter or anti-rust oil should be used to prevent the rust of the exposed parts and mechanical parts, and the gears, sprockets and other parts should be lubricated every half a month. Leveling: The quality of the leveling and the construction quality also have a necessary relationship. Some buildings have a lot of dust or other sundries, which will cause the leveling machine to level the concrete and become dirty, which will lead to unqualified construction. Therefore, it is usually necessary to Remember to tell Xun Phi to clean the leveling in time. Oil replacement: The engine oil and hydraulic oil in the machine need to be replaced after a period of use. Most people think that it is enough to drain the oil in the oil tank and fill up with new hydraulic oil. But at this time, there will be a lot of old grease trace hydraulic oil in the hydraulic oil pipe. When the equipment is in use, the new oil and the old oil will be mixed together, which will shorten the service life of the new oil. The correct oil change procedure is to drain the hydraulic oil in the hydraulic oil tank first, clean the oil tank and then add new hydraulic oil. Then remove the circuit main pipe, start the engine and run it at a low speed to make the oil pump work, operate each mechanism separately, and use new hydraulic oil to discharge the old oil in the circuit one by one until new oil flows out of the oil return main pipe. Finally, connect the oil return main pipe to the fuel tank, and add new hydraulic oil to the fuel tank to the specified position. Precautions The usual maintenance and maintenance of machinery is important, but it is more important to choose a good machine equipment. VANSE laser leveling machine is your best choice!
