Domestic *8983 batches of rotary drilling rigs stationed in the construction of Qinghai-Tibet Railway

The Qinghai-Tibet Plateau is regarded as a forbidden area for pile foundation construction, and the Chinese have created a myth here, and the creators of this legend are many of our Sanyi people, especially in terms of foundation engineering, Sany rotary drilling rig is the leader of the domestic *8983 batch stationed at the Qinghai-Tibet Railway construction site. Sany's SR220C series rotary drilling rig was stationed in the Qinghai-Tibet line in August 2003 and became the first 8,983 domestic equipment to enter the plateau construction. A single rotary drilling rig generated more than 6 million yuan in half a year, overcoming difficulties such as plateau, low temperature and harsh construction environment, and withstood severe tests. According to the traditional construction method, the permafrost must be destroyed to lay the foundation, and this is the forbidden area of construction. Our rotary drilling rigs cleverly solve the problem of laying deep and solid foundations without destroying the permafrost. The success of the pile foundation construction of the Qinghai-Tibet Railway has opened the way for Sany to move towards the Chinese piling machinery *8982 brand.
