    To prevent the problem of flatness of concrete pavement, it is necessary to strictly control the quality in various links such as construction preparation, concrete pouring, pavement paving and subsequent maintenance. The specific measures are as follows:   – Do a good job of roadbed treatment: The roadbed is the foundation of the road surface and must be guaranteed to be solid, stable and uniform. Before construction, the original ground should be carefully cleaned, weeds, tree roots, garbage and other debris should be removed, and the soft soil, silt and other unfavorable geological areas should be replaced and reinforced. Fill and compact the roadbed according to the design requirements, control the moisture content of the fill, fill and compact in layers, ensure that the compaction meets the standard, and avoid uneven settlement of the roadbed in the later stage and affect the flatness of the road surface. – Precise measurement and layout: Use high-precision measuring instruments, such as total stations, levels, etc., to accurately measure and lay out the center line, side line, elevation, etc. of the road surface. During the construction process, the measurement control points should be reviewed regularly to ensure the accuracy of the measurement data. At the same time, according to the measurement results, set the road template or the guide line of the paver to provide an accurate benchmark for road construction. – Check construction equipment: Ensure that the performance of construction equipment such as concrete mixing equipment, transport vehicles, pavers, and rollers is good and can operate normally. Carry out regular maintenance and maintenance of the equipment, and conduct a comprehensive inspection and commissioning of the equipment before construction. For example, check whether the screed of the paver is flat, whether the vibrating device is working properly, whether the roller wheel of the roller is evenly worn, etc., to ensure that the equipment operates stably during the construction process and avoid problems with the flatness of the road surface due to equipment failure.   – Control concrete mix ratio: According to the road design requirements and construction conditions, determine the reasonable concrete mix ratio through experiments. Strictly control the quality and amount of raw materials such as cement, sand and gravel, water, and admixtures to ensure that the workability, strength, and durability of the concrete meet the requirements. In particular, attention should be paid to controlling the slump of concrete. The slump should not be too large or too small. If it is too large, it will easily cause concrete segregation and surface water seepage, affecting the smoothness of the road surface; if it is too small, it will make it difficult to spread and vibrate the concrete. – Ensure the quality of concrete mixing: Use a forced mixer to mix to ensure that the concrete is mixed evenly. Strictly control the mixing time. Determine the appropriate mixing time according to the mix ratio of concrete and the performance of the mixer. Generally, it should not be less than 90 seconds to ensure that the various components of the concrete are fully mixed to avoid uneven distribution of cement slurry and stone clumping, which will affect the working performance of the concrete and the smoothness of the road surface. – Reasonably arrange concrete transportation: Choose appropriate transportation vehicles to ensure that concrete does not segregate or leak during transportation. According to the distance and traffic conditions of the construction site, reasonably arrange the number of transportation vehicles and transportation routes to ensure that concrete can be supplied to the construction site in time, avoid waiting for too long during transportation, resulting in excessive slump loss, and affecting the quality of concrete spreading and vibration.   – Standardize paving operation: When using a paver for concrete paving, adjust the working parameters of the paver, such as the elevation angle of the screed, vibration frequency, paving speed, etc. The paver should move forward at a uniform speed, and the speed is generally controlled at 2-3m/min to avoid too fast or too slow speed. During the paving process, a special person should be arranged to follow the machine and deal with the leakage and uneven parts on both sides of the paver in time. If manual paving is used, the paving thickness and surface flatness must be strictly controlled. Use tools such as scrapers and shovels to roughly flatten the concrete, and then vibrate it with a vibrating beam or a flat vibrator. – Strengthen vibration control: Vibration is a key link to ensure the density and flatness of concrete. According to the slump and paving thickness of the concrete, choose the appropriate vibration equipment and vibration method. Generally, a combination of an inserted vibrator and an attached vibrator is used for vibration. The inserted vibrator should be inserted vertically into the concrete, and the vibration points should be evenly distributed. The spacing should not be too large, generally about 1.5 times the radius of the vibrator. The vibration time is based on the concrete surface no longer having bubbles, slurry and sinking, generally 20-30 seconds. The attached vibrator should be installed on the formwork to make the concrete dense by vibrating the formwork. During the vibration process, the vibrator should be prevented from colliding with the formwork, steel bars and force transmission rods, so as not to affect the flatness and structural dimensions of the road surface.   – Do a good job of finishing: After the concrete is vibrated, the finishing operation should be carried out in time. The finishing is generally done in two times. The first finishing is done after the concrete surface absorbs water. A wooden trowel is used to scrape the surface slurry, gravel, etc. to make the road surface flat. The second finishing is done before the concrete is initially set. An iron trowel is used for fine finishing to make the road surface flatter and smoother. At the same time, attention should be paid to controlling the strength and number of finishing to avoid excessive finishing, which may lead to excessive thickness of cement slurry on the surface, cracks, peeling, etc. – Standard roughening treatment: After finishing, roughening should be done in time to increase the roughness of the road surface and improve driving safety. The depth and spacing of roughening should be uniform. Generally, the depth of roughening is 2-3mm and the spacing is 2-4cm. Roughening can be done with tools such as a roughening machine or a broom. The roughening direction should be consistent with the driving direction of the road surface to ensure uniform and beautiful roughening quality.   – Timely maintenance of the road surface: After the concrete road surface is poured, it should be maintained within 12 hours. The maintenance method can be to cover with moisturizing materials such as geotextiles and straw mats, and regularly sprinkle water to keep it moist, or spray curing agents for maintenance. The maintenance time is generally not less than 7 days. For high-strength concrete or concrete constructed in high temperature and dry environments, the maintenance time should be appropriately extended. During the maintenance period, it is necessary to ensure that the concrete surface is always moist to avoid shrinkage cracks caused by water loss in the concrete, which will affect the flatness of the road surface. – Strict traffic control: During the maintenance of the concrete pavement, strict traffic control must be carried out, and all vehicles and pedestrians are prohibited from passing on the road surface until the concrete reaches the design strength. Before the road surface is opened to traffic, the road surface must be inspected and accepted to ensure that the various indicators such as the flatness and strength of the road surface meet the design requirements. At the same time, obvious warning signs should be set up on the road surface to guide vehicles and pedestrians to bypass the construction area to avoid damage to the road surface that has not been fully formed.       ARMOUR JOINT CONCRETE LASER LEVELING MACHINE LIGHT TOWER POWER TROWEL STEEL FIBER TRACKED MINI DUMPER  

    The reduction in labor reliance and the improvement in labor efficiency through the use of power trowel are revolutionary. The following is visually illustrated through a specific comparative case and detailed data dissection. Project area: 10,000 square meters Concrete thickness: 15 centimeters Construction requirements: Meet the industrial standards for flatness (±3mm/2m) and smoothness (finishing). Strong laborers (carrying and preparing) : 4-5 people Plastering workers (responsible for finishing the surface) : 8-10 people (experienced master craftsmen are required) Total number of people: 12 to 15 people working simultaneously. Workers need to wear boots, line up on the initially set concrete, and use tools such as wooden power trowel and iron power trowel, bending over to repeatedly smooth and smooth it out. This is an extremely physically demanding process and a huge test for the workers' waists and arms. Because it involves multiple people working together, it is difficult to ensure even force application and consistent steps, which easily leads to a "wavy" ground. Daily completed area: A skilled team can complete a maximum of 800 to 1,000 square meters in a day (calculated based on 8 to 10 hours). Total construction period: It will take 10 to 12 days to complete 10,000 square meters of ground. Quality risk: Highly dependent on the technical proficiency and physical condition of workers. The construction quality dropped significantly after fatigue in the afternoon, and the joints were prone to unevenness. Extremely high labor costs: Calculated based on 15 people, the daily labor cost is huge. High management costs: It requires an outstanding foreman to coordinate over a dozen people, making management very difficult. Hidden costs: The risk of work-related injuries caused by workers' fatigue work and the cost of rework due to substandard quality. Power trowel operator: 2 (take turns to operate to prevent fatigue) Auxiliary workers (responsible for corner and pipeline handling) : 3-4 people Total number of people: 5 to 6. After the concrete is spread, vibrated and leveled, it is allowed to set initially. The operator drives the power trowel machine into the site to carry out large-scale rough power trowel (installing the disc) and fine power trowel (installing the power trowel). Auxiliary workers simultaneously use small hand-held power trowel or manually handle corners, column bases, and the area around equipment foundations that machines cannot reach. Daily completed area: One power trowel team can easily complete 2,500 to 3,000 square meters in a day. Total construction period: It only takes 3 to 4 days to complete 10,000 square meters of ground. Quality Assurance: The flatness is guaranteed by the machine, uniform and consistent, eliminating fluctuations caused by human factors. The surface density and smoothness are much higher than those of artificial ones. Labor costs have been significantly reduced: the number of employees has decreased by more than 60%. Equipment cost: The rental or depreciation expenses of the power trowel machine need to be borne, but they are far lower than the labor cost savings. The overall cost has significantly decreased: The shortening of the construction period has led to a reduction in management and rental fees, and the one-time excellence in quality has avoided rework. The overall cost-effectiveness is extremely high. Comparison dimension Pure manual operation Mechanized operation Enhance the effect Quantity of labor force 12 to 15 people Five to six people Reduce by approximately 60% to 70% Daily completed area 800-1,000 square meters 2,500-3,000 square meters Increase by approximately 200% to 300% Per capita daily efficiency Approximately 70 square meters per person Approximately 500 square meters per person Increase by more than 600% Total construction period 10 to 12 days Three to four days Shorten by approximately 60% to 70% Quality consistency Dependent on individuals and unstable Guaranteed by machines, it is uniform and stable From "craftsmanship" to "industrial standards" Labor intensity of workers Extremely high (bending over, carrying heavy loads Medium (standing to operate the machine) Significantly reduced occupational health protection Replacing ten with one, directly substituting heavy labor: The working efficiency of one machine is equivalent to that of a dozen skilled workers, directly solving the problems of "labor shortage" and "high labor costs". Technology empowerment lowers the skill threshold: Traditional plasters need several years to master solid skills. A power trowel operator can start working after a short period of training and can produce more stable quality. Transform reliance on "the experience of experienced masters" into replicable "standardized operations". Speed wins, shortening the project cycle: A shorter construction period means faster delivery and use, creating earlier returns for the owner, while saving a significant amount of on-site management costs and equipment rental costs for the construction party. The quality leap achieves dual benefits: higher flatness and better surface strength. It not only meets the strict requirements of modern industrial floors, reduces dust and wear problems during later use, but also completely avoids the rework losses caused by substandard quality. This is a "hidden" efficiency improvement. Conclusion: The use of a power trowel is not merely a simple "machine replacing human", but a comprehensive upgrade of the construction process. It has achieved a deep reduction in reliance on labor and a leapfrog improvement in labor efficiency by significantly reducing the number of workers, greatly enhancing operational efficiency, and fundamentally ensuring construction quality. It is an indispensable core equipment in modern concrete floor construction.   Note: The parameters provided in this document are for reference only and are not mandatory.
