On the morning of February 27, 2016, the Jiangsu demonstration project "Dawa-Longcheng 220kV Line Project" of the fully mechanized construction of the State Grid was successfully started. The KR80 small rotary drilling rig customized by Jiangsu TYSIM Machinery was used in the project. The use of this equipment for the hole-forming construction of the pile foundation of the line tower means that China's power grid construction has taken a solid step towards a new full-process mechanized construction. The whole process of mechanized construction has changed the way of line engineering construction, which used to be dominated by manpower and supplemented by machinery, and realized the transformation of line engineering construction to mechanized mode, which is conducive to improving the safety, quality, efficiency and technological level of power grid construction. It is an inevitable requirement for the development of power grid construction technology, and the construction equipment of transmission engineering with scientific technology, customized specialization and standard modularization is the effective support for the whole process of mechanized construction. The special rotary drilling rig for transmission lines developed by TYSIM Machinery is meeting this need. The person in charge of the State Grid said that the performance of the product greatly exceeds the expected requirements of the demander. Through this project, the strategic cooperation scope between TYSIM and the State Grid will be further promoted. This customized product is specially designed for the special requirements of the State Grid system and has low transportation height and small transportation length with the concept of integration, lightness, safety and environmental protection, and the green small rotary drilling rig, which can be transported by the whole machine and quickly alight, is mainly used to solve the problems of low efficiency, high risk and backward technology in the manual construction of the foundation of the national power grid tower or the construction of the old pile machine, which belongs to the international.

At present, the construction of the equipment has been completed in G38 section, with a drilling diameter of 800mm and a depth of 14m. TYSIM KR80 small rotary drilling rig is carefully developed, boldly innovated and adopts a number of international science and technology on the basis of the idea of "technology development adapting to the market. Compared with the traditional rotary drilling rig, the KR80 small rotary drilling rig is characterized by light weight, small volume, large transportation machine height of 3.4 meters and transportation weight of 24 tons. It also adopts the international scientific overall transportation concept with rods for rotary drilling rigs, which truly realizes the mode of getting off the bus and going, greatly reduces the labor intensity of operators and the time of disassembly and installation, and greatly saves the transportation cost. At the same time, KR80 has the advantages of less personnel and high degree of automation. Compared with the old equipment, it is flexible and efficient, and truly realizes fully mechanized operation. KR80 machine control adopts international scientific hydraulic electrical control system, high degree of automation, can realize automatic adjustment of verticality, automatic return to zero rotation angle, depth real-time display, touch protection, lifting force display and many other automation functions. KR80 small rotary drilling rig has a power head torque of 80kN.m and a high rotation speed of 30r/min, thus greatly improving the construction capacity of the equipment. The core components of the whole vehicle are imported with original packaging, with strong power and stable performance. Equipped with traction winches, the driving capacity of the drilling rig in complex areas is greatly improved. KR80 rotary drilling rig adopts mud wall protection for efficient hole formation, which shortens the construction time by half compared with the original, greatly reduces the amount of mud during the construction process, and reduces the environmental pollution caused by mud. At the same time, in terms of after-sales service, TYSIM Machinery adheres to the purpose of "creating value for customers", and all after-sales problems are effectively solved in time, the high efficiency and high reliability of the green rotary drilling rig customized by the State Grid have greatly shortened the construction period and saved the cost, and won the unanimous praise of the leaders of the State Grid.

Adhering to the core concept of "focus, creation and value", it is committed to creating other values for customers. TYSIM is a leading enterprise focusing on the development of small and medium-sized piling machinery in China. KR series small rotary drilling rigs are suitable for various projects of industrial and civil construction and urbanization. They are well received by customers at home and abroad for their advantages of high construction efficiency and reliable performance. They will become the preferred product for pile foundation construction of "new urbanization" in China, promote the upgrading of domestic civil engineering pile foundation construction and create a "domestic and international well-known" professional pile brand.
