What damage will improper blade angle adjustment cause to the power trowel blade?

Construction technical requirements of concrete laser leveling machine When we use the concrete laser leveling machine for construction, we need to understand some relevant technical requirements, such as the requirements for concrete or formwork, and the degree of coordination of various details, etc. There are also certain requirements. These problems need to be properly arranged before they can be directly adjusted Otherwise, there may be some problems during the construction process. 1. Requirements for concrete and formwork   01. Concrete must be produced, conveyed or pumped to the flooring project site by commercial concrete production plants. 02. Concrete specifications: C25~C30 concrete, the strength of which is not less than 25MPa in 28 days, according to the design requirements. 03. Water-cement ratio: no more than 0.5, no water can be added during the feeding process. 04. Cement: Use ordinary Portland cement with a grade of not less than 42.5.   05. 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. 06. 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%. 07. Concrete slump: 14±2cm, maximum 16cm. 08. 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 corporation 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 area around the formwork, the wall, the column, the trench, the equipment foundation, the floor drain or the surrounding of the pipeline and other equipment that cannot be leveled requires 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.

Concrete laser leveling machine is widely used and is an advanced machine used to super-level and level concrete floors. Its application scope can be roughly divided into two categories: indoor floor engineering and outdoor floor engineering. These two types have small subdivisions. The following is a detailed introduction to the subdivision range of concrete laser leveling machines, as well as an introduction to such projects that VANSE Machinery's products have done. Nowadays, concrete laser leveling machines are more and more widely used, and the specific scope of application can be divided into two categories: 1. Indoor floor 1) Industrial plants, workshops, automated three-dimensional warehouses: VANSE Machinery has done such projects as Harbin Haier workshop, Beijing Benz workshop, Baoding Great Wall Motor No. 5 spraying workshop, Shandong Classic Group steel structure production line workshop and other projects. 2) Clean workshops for electronic appliances, food materials, medicine, etc.: Such projects that VANSE Machinery has done include: Suzhou Samsung Electronics Factory, Shandong Xingda Ecological Winery, Shandong Baisheng Biological Workshop, Shandong Yuda Medical Workshop and other projects. 3) Large warehouse supermarkets, logistics centers, exhibition centers, etc.: Such projects that VANSE Machinery has done include: Xi'an Fuju Home Plaza, Shenzhen Wal-Mart Supermarket, Wuhan Vipshop Logistics Park, Guangxi Convention and Exhibition Center, Tianjin Yupei Logistics Park and other projects. 2. Outdoor floor 1) Wharf, container yard, freight yard: Such projects that VANSE Machinery has done include: Hubei Xiangzhou Industrial Park, Shanxi Shenlong Energy Coking and other projects. 2) Airport runways, aprons, and parking lots: Such projects that VANSE Machinery has done include: Shandong Xinbaihui underground parking plant, Changchun FAW-Volkswagen parking lot, Hebei Hualian Supermarket large-scale underground parking lot, Sichuan Wanda Plaza large-scale underground parking lot, Hubei Xiangyang Dongjin Century City underground parking lot and other items 3) Squares, residential grounds, municipal roads, etc.: VANSE Machinery has done such projects as: Nanjing Huawei Electronics Company Floor, Shenyang Electronics Factory Floor Integration, Sichuan Hualian Plaza, Hubei Xiangyang Dongjin Century City and other projects. Shandong Yanzhou VANSE Machinery Technology Co., Ltd. is the only high-tech enterprise in China that integrates R&D, manufacturing, sales and technical services, specializing in concrete laser leveling machines. The use of "Leilong" brand concrete laser leveling machine can reduce high-intensity labor by about 60%, save about 50% of construction costs, shorten about 50% of construction period, and increase the strength and compactness of the floor by about 25%. The company has always been "people-oriented, technology-leading, honest management, creating a well-known brand" as its purpose, providing customers with reliable products, perfect services, common development, and creating success.

CORRECT USE OF LASER LEVELING MACHINE The laser leveling machine is an indispensable equipment in the construction industry. It is inseparable from the construction of large highways. To ensure the smooth progress of the construction and the smoothness of the road surface, it is necessary to master the correct use of the laser leveling machine. Secondly, read the instruction manual of the equipment before use, because in this way you can get familiar with the internal structure of the equipment as soon as possible, so as to achieve correct operation. The following laser leveling machine manufacturers will take you to understand the correct use of the laser leveling machine. The knowledge shared by laser leveling machine manufacturers for you basically comes to an end here.
