From 1993 to 1994, in the foundation infusion project of Shanghai Pudong Yaohan Building, all the methods of rotary boring and drilling were successfully used, which played a role in helping the country.
In the foundation construction of the Fifth Ring Road in Beijing, the majority of pile rigs have occupied more than 30 units.
The large-scale construction of the national key project Qinghai-Tibet Railway was officially launched in 2001. In the construction section of the Qinghai-Tibet Railway Gera section, the strata are mostly permafrost, gravel, irregular shale, and soft-hard interlayer limestone. The thickness of frozen soil reaches more than 100 meters.
China Railway Group uses rotary drilling and drilling construction technology. Since March 2002, a large number of pile drilling machines have entered the construction of the Qinghai-Tibet Railway. By the middle of August 2002, there were more than 100 sets, including 9 domestic equipment.
The heavy use of construction equipment on the Qinghai-Tibet Railway has attracted special attention from construction and manufacturing enterprises, which has undoubtedly promoted the development and application of pile drilling machines.
In 2000, the RD18 drilling rig of XCMG Group was successfully developed, with a maximum hole diameter of 2m and a maximum drilling depth of 60m. Three were used in the construction of the Qinghai-Tibet Railway, and many were used in the Beijing project.
In 2001, Beijing Jingwei Juli Engineering Machinery Co., Ltd. successfully developed ZY120, ZY160, and ZY200 pile drills and participated in the construction of the Qinghai-Tibet Railway.
In March 2003, SANY Heavy Industry successfully developed the crawler retractable SR220C rotary drilling rig, which has been tested in construction sites of the Qinghai-Tibet Railway Beijing Yintai Building, Anshan Steel Blast Furnace, Tianjin, Nanjing and other construction sites. Construction site-16 pile rigs are used at one time.
Due to the pulling of the Beijing Olympic Games, Shanghai World Expo, and the high-speed passenger dedicated line project, it has provided a huge space for development of pile drilling machines. In recent years, the large number of rotary drilling methods in China has greatly increased the use of pile drilling machines. It is the success of new products developed by many manufacturers of pile drilling machines, which greatly promoted the production and application of this product.
