According to a recent disclosure by Shougang Group, the prototype of the ST series multi-functional double-sleeve casing drilling rig independently developed by Shougang Baekyu Foundation Machinery Technology Co., Ltd. has been successfully developed. The drilling rig owns the core technology of independent intellectual property rights, and the technical level is the first in China and has been applied for. National invention patents.
According to reports, the ST series of multi-spindle rotary drilling rigs are construction machinery products used in infrastructure construction in various fields such as civil construction, transportation, water conservancy, and environmental protection. It can be drilled into piles under various complicated geological conditions; used for the construction of reinforced concrete cast-in-place piles and CFG piles; applicable to the construction of composite piles of various steel pipes and concrete; and the corresponding accessories can be used to set precast cement without vibration. Pipe piles, steel pipe piles and other prefabricated piles; configuration of the corresponding accessories, deep mixing and deep mixing can be carried out on soft foundations.
Its main technical features are: the use of a unique compound dual-rotation two-speed power head drive, the use of a unique dual-rotation drilling of the drill pipe and outer drill sleeve; configuration of a variety of combination drilling tools, in a variety of hard and soft formations, Easy installation of drilled piles under complex geological conditions such as crushed stone and rock formation; due to the protection of outer drill sleeves, the pile holes do not need to be protected by mud or collapse, and the vertical precision of the drilling holes is high and the construction speed is fast.
