The one-step forming construction technique for high-precision, wear-resistant floors without cutting joints, which is based on laser leveling technology

– Environmental protection and energy saving: Electric trowels are powered by electricity and do not produce exhaust gas emissions. They are more environmentally friendly and have relatively low operating costs. Long-term use can save energy costs. – Less noise: Compared with internal combustion trowels, electric trowels produce relatively low noise when working, which helps reduce noise pollution at the construction site, improve the working environment, and reduce noise interference to surrounding residents and operators. – Easy to operate: The structure of the electric trowel is relatively simple and easy to operate. Usually, you only need to connect the power supply and press the switch to start. There is no need to perform complicated operations such as refueling and starting like the internal combustion trowel. In addition, the speed of the electric trowel is relatively stable, and it is easy to control the leveling and polishing effect. – Low maintenance cost: Since the electric trowel does not have complex mechanical parts such as internal combustion engines, it does not need to regularly replace engine oil, air filters, etc. Its maintenance work mainly focuses on the inspection and cleaning of parts such as motors, wires and switches. The maintenance cost is relatively low and maintenance is also relatively convenient. – Dependence on power supply: The electric trowel needs to be connected to an external power supply to work, which limits its working range and flexibility. In some construction sites without power sockets, it is necessary to equip a longer power cord or use a generator to provide electricity, which is not convenient to use, and the existence of the power cord may affect the convenience and safety of operation. – Limited power output: Generally speaking, the power output of the electric trowel is weaker than that of the internal combustion trowel. For large-area, high-intensity concrete troweling operations, it may take longer to complete the task, and the work efficiency is relatively low. – Not suitable for harsh environments: When using an electric trowel in a humid or dusty environment, special attention should be paid to the waterproofing and dustproofing of the motor and wires to avoid safety accidents such as leakage or short circuit, which will affect the normal use and life of the equipment. – Powerful: The internal combustion trowel uses gasoline or diesel engines as the power source, has high power and torque output, can easily cope with various complex concrete troweling conditions, and is especially suitable for large-area, high-strength concrete surface troweling operations. It has high work efficiency and can complete a large amount of work in a short time. – Not limited by power supply: The internal combustion trowel does not need to rely on external power supply, can be operated anytime and anywhere, has high flexibility and mobility, and is particularly suitable for use in some remote areas or construction sites without power supply. – Environmental pollution: The internal combustion engine will produce exhaust emissions during operation, which contain pollutants such as carbon monoxide, hydrocarbons, and nitrogen oxides, which will cause certain pollution to the environment and are not conducive to environmental protection. – High noise: The internal combustion trowel generates a lot of noise during operation, which will cause certain damage to the surrounding environment and the hearing of the operator, and may also affect the life and rest of residents near the construction site. – High maintenance cost: The engine and other mechanical parts of the internal combustion trowel are relatively complex and require regular maintenance and upkeep, such as changing the engine oil, air filter, spark plug, etc. The maintenance cost is relatively high, and the engine maintenance also requires professional technology and tools. Once a failure occurs, the maintenance difficulty and cost are high. – Fuel consumption: The internal combustion trowel needs to consume fuel to provide power. After long-term use, the fuel cost is high. In some areas, the supply of fuel may not be as convenient as electricity, and fuel needs to be reserved in advance, which increases the complexity and cost of use.

    According to the technical parameters in the product manual of Shandong Vanse Machinery Technology Co., LTD., and in combination with the strict requirements of airport runway construction for extremely high flatness, large area continuous operation, equipment stability and high-precision control systems, the following models are professional choices that can meet the needs and are arranged in the recommended order: These models are the preferred choice for high-standard projects such as airport runways and large industrial floors due to their high power, wide paving, advanced control systems and outstanding stability. Recommendation reason Maximum paving width: 4 meters, which is the model with the largest width in the manual. It can greatly improve the efficiency of large-area continuous paving and the flatness of the joints. Strong power: 57kW diesel engine, providing sufficient power for high-intensity and long-term continuous construction. Advanced control system: Clearly marked as "Compatible with 3D profiler system". This is the core configuration that meets the extremely high precision requirements of airport runways. The 3D system, controlled by GPS or total stations, can adjust the elevation in real time, perfectly achieving complex slopes and designed elevations, with a precision far exceeding that of traditional single-point lasers. High adaptability: The body can rotate 360 degrees infinitely and be leveled with one click, which can flexibly handle various situations during construction. Professional configuration: Standard cleaning system, soft landing system, etc., to ensure the long-term and stable operation of the equipment. Recommendation reason Balanced performance: 3.1 meters paving width, achieving a good balance between efficiency and flexibility. Long boom: 6-meter telescopic boom, providing a larger working coverage range and reducing the number of equipment movements. Also compatible with 3D systems: The product features clearly state that it has the technical foundation for achieving high-precision construction. Multi-mode steering: two-wheel, four-wheel, crab steering, providing greater maneuverability in narrow or complex areas. For the construction of runway accessory areas, taxiways or base layers with slightly lower precision requirements, the following models can also be considered as alternatives: WS550/ YZ28-4S/ WS940/ WS940C ride-on concrete laser leveling, among which WS940C also supports 3D system construction A 3D control system must be used: No matter which model is chosen, it is necessary to select or confirm its compatibility and actually install a high-precision 3D intelligent paving control system. This is the technical guarantee for achieving millimeter-level accuracy in the slope and elevation of the longitudinal and transverse slopes of airport runways. Give priority to the Boom Type model: The boom type leveling does not rely on formwork. It can control the paver head through laser or 3D signals, achieving large-scale seamless continuous operation and fundamentally reducing construction joints. This is the key to ensuring the overall flatness of the runway. Equipment stability and reliability: Airport runway construction is often characterized by tight schedules and high intensity. Particular attention should be paid to the: Engine brand and power (such as Yanmar, Kubota). Reliability of the hydraulic system. Strength of structural components. Comprehensive construction plan Concrete proportioning and conveying: It needs to be used in conjunction with high-efficiency concrete pavers (such as the BL-360 concrete distributor in the product manual) to achieve rapid and uniform sprouting. Subsequent process connection: After leveling, a large ride-on power trowel (such as VS836/VS1046) should be immediately used for finishing to meet the final density and wear resistance requirements of the runway surface. Joint treatment: The Armour joints of the runway need to be professionally treated with high-performance Armour joints (such as AFJ type, S type) to protect the edge of the runway and transfer the load. For the high-standard construction of the main surface layer of airport runways, the YZ40-4E is highly recommended. Its maximum paving width and powerful performance make it most suitable for large-scale and efficient operations. The next recommendation is the YZ30-4E, which has obvious advantages in terms of mobility and coverage. The most crucial point is to ensure that the selected model is equipped with and actually applies a high-precision 3D intelligent control system. Before making the final decision, it is strongly recommended: Contact Vanse ([email protected]) for more detailed technical solutions and 3D system configuration instructions. Request successful cases and construction data of relevant aircraft models in similar large airports or key infrastructure projects. If conditions permit, arrange on-site inspection and equipment demonstration. Only by choosing the right equipment and combining it with scientific construction techniques can the airport runway meet the highest quality standards of being "as smooth as a mirror and sturdy and durable".   Note: The parameters provided in this document are for reference only and are not mandatory.

Concrete has strong compressive resistance but weak tensile resistance. The double-layer steel mesh significantly improves the tensile resistance of the pavement through the synergistic effect of the upper and lower layers of steel bars, reducing the risk of cracking caused by load or temperature stress. The double-layer steel mesh can evenly disperse the concentrated load to a larger area, reduce local stress concentration, and extend the service life of the pavement. When concrete shrinks or bends, the steel mesh can restrain the development of cracks and prevent cracks from penetrating the entire pavement structure. For pavements that frequently bear dynamic loads (such as heavy vehicle rolling), double-layer steel mesh can enhance the fatigue resistance of the structure and delay aging and damage.   Airport runways, port terminals, highways and other pavements that need to bear high loads. In areas with a high risk of uneven foundation settlement, double-layer steel mesh can reduce structural cracking caused by foundation deformation. In high temperature or severe cold areas, steel mesh can help resist temperature stress; in humid environments, double-layer arrangement can increase the thickness of the protective layer and improve corrosion resistance.   Usually, the upper steel bar is located 5~10cm below the top of the road surface, and the lower steel bar is close to the bottom. The middle is fixed by a bracket or a horse stool to ensure the thickness of the protective layer (generally 3~5cm). The diameter and spacing of the steel bar need to be determined according to the design load calculation. The common specifications are φ8~φ16mm and the spacing is 15~30cm. The steel mesh is connected by binding or welding to ensure integrity; the steel bars can be increased or reinforced in local weak areas.   Double-layer steel mesh may affect the fluidity of concrete. The slump needs to be strictly controlled, and vibration compaction should be ensured to avoid voids. Lay the bottom steel mesh first, and then lay the upper steel mesh after the concrete is poured (or pour in two times). The specific needs to be adjusted according to the design requirements. Perform maintenance in time after construction to prevent steel corrosion and concrete shrinkage and cracking. Through reasonable design and construction, the double-layer steel mesh can significantly improve the comprehensive performance of concrete pavement, especially suitable for projects with high requirements for durability and safety.
