Sany full hydraulic horizontal high pressure rotary jet drill fills the domestic gap

Recently, the SJ180 horizontal high-pressure rotary jet drilling rig of the all-hydraulic new tunnel advanced support construction equipment developed by Sany Group Beijing Pile Machine Co., Ltd. successfully went offline, filling the blank of domestic all-round high-pressure jet grouting technology and equipment production, and solved the problem. The problem of advanced support for complex strata in domestic tunnel construction.

At present, the construction engineering method and equipment manufacturing industry of China's underground support engineering are backward, resulting in tunnel collapse accidents. In 2006, there were dozens of major tunnel collapses, such as the collapse of the Yunnan Daly Railway Tunnel and the Beijing Subway Line 10. The collapse of the landslide, the collapse of the Dazhou in Sichuan, etc., has changed the status quo of the backward industry has become a mission and belief of the industry.

Beijing Pile Machine adheres to the guiding principle of building a company-led, market-oriented, industry-university-research technology innovation system, and is committed to transforming traditional industries with high-tech, promoting the strategic adjustment of industrial structure and technological progress in the pile machinery industry. . In 2006, Beijing Pile Machine and China Metallurgical Group Construction Research Institute signed a strategic cooperation agreement to transform and innovate the traditional underground support technology and equipment, and became the first in China to have a tunnel full-scale high-pressure jet grouting (horizontal rotation The company that sprays technology and equipment production has a number of independent intellectual property rights and patented technologies. This technology will greatly promote the application and promotion of China's horizontal high-pressure rotary spray method, and accelerate the pace of the industry and international standards.

After learning that the SJ180 horizontal high-pressure rotary jet drilling rig developed by Beijing Pile Machine was successfully launched, Chairman Liang Wengen sent a congratulatory letter to the first time. He hoped that Beijing Pile Machine would give full play to talents and technical advantages and accelerate the serialization and upgrading of pile driver products. Replacement.
