Pile machinery: expect more new products

Guide: pile machinery is mainly used for the construction of various pile foundations, foundation improvement and reinforcement, underground diaphragm walls and other special foundations. At present, it has accounted for 95% of the pile foundation construction in urban construction and bridge construction. Among them, due to its high efficiency, less pollution and multiple functions, rotary drilling rigs are widely used at home and abroad

pile machinery is mainly used for the construction of various pile foundations, foundation improvement and reinforcement, underground diaphragm walls and other special foundation projects. At present, it has accounted for 95% of the pile foundation construction in urban construction and bridge construction. Among them, due to its high efficiency, less pollution and multiple functions, the rotary drilling rig has been widely used in the construction of cast-in-place piles at home and abroad, especially in developed countries in Europe and Asia

due to historical reasons, the development of domestic piling machinery is relatively slow, and the current backward products and pile foundation construction technology can no longer meet the needs of the rapid development of large-scale foundation design and construction. At the same time, due to the lack of corresponding national standards in the process of developing pile machinery products such as rotary drilling rigs, domestic enterprises are more common, which has buried hidden dangers for the further development of the industry

it is understood that China has gradually introduced foreign advanced hydraulic rotary drilling rigs since the 1980s, which has led to the fastest growth in the central and Southern markets of the United States, creating a new situation of bored cast-in-place pile technology. Some domestic construction machinery manufacturers have realized that the piling machinery products have a good development prospect, and have increased the research and development of piling machinery products. It is reported that at present, China has been able to mass produce diesel pile hammer, hydraulic pile hammer, as the name suggests, vibratory pile hammer, diesel hammer pile frame, vibratory pile sinking and pulling frame, pile pressing machine, hole forming machine, underground continuous wall grooving machine, soft foundation reinforcement machinery and its supporting equipment in 10 categories, nearly 20 series of piling machinery products with more than 200 models and specifications

according to incomplete statistics, at present, the market ownership of rotary drilling rigs in China has reached more than 500, but more than 90% of them are foreign brands, most of which are products of Italian soil power company, Italian horse company, Maite company and German baoe company. Although the domestic piling machinery industry has been involved, it has not formed a scale. The domestic piling machinery industry is facing the dual pressure of low overall strength and the impact of foreign imported products. The development of piling machinery in China is at a special stage. At present, there are more than 10 domestic rotary drilling rig manufacturers, but few can really form a scale, and the product positioning is the same, and the product selection is repeated. With the commencement of key projects such as the Qinghai Tibet railway, the demand for high-end piling machinery in the domestic market has soared, resulting in the entry of foreign piling machinery products into the Chinese market, especially the national key projects, rotary drilling rig products are basically imported brands

from the technical level, the domestic rotary drilling rig still has a series of problems that need to be further improved, such as poor hydraulic system configuration, domestic drill pipe can not meet the user's performance requirements, the appearance of the whole machine and the layout of the instrument panel in the operating room. In addition, the reliability of various safety devices needs to be solved as soon as possible. If there is no breakthrough in these aspects, it will greatly affect the overall development of the domestic pile machinery industry. Of course, we cannot completely follow the big foreign companies and blindly emphasize high-grade and high configuration. China's national conditions require that the main performance of domestic piling machinery products meet the requirements. 10. The battery shall be stored for a long time, and the price must be accepted by the majority of Chinese users, so that the piling machinery industry can develop rapidly in the fierce market competition. Therefore, the development of low-cost and high-quality products in line with China's national conditions has become the current (1) adjustment of the loading speed of the main experimental force; (2) Selection of experimental force (150kg:1471n 100kg/980.7n 60kg/588n); (3) carefully install the durometer indenter It is urgent for the development of domestic piling machinery industry
