The traditional drilling method is to use a pile driver to directly pile. However, the underlying foundation layer is often structurally strong, with hard rock blocks, and using a pile driver to directly pile not only makes it difficult to construct to the specified depth, but also causes problems such as pile body skewing and deformation, and in extreme cases, it can also cause pile body or equipment damage.

[0003] In view of the above problems, during actual construction, construction personnel often disassemble the pile driver's pile hammer and replace it with a drilling assembly to achieve the purpose of road surface drilling. However, on-site assembly of the drilling assembly not only has low construction efficiency, cannot achieve fine adjustment of the drilling bit positioning size, and the assembly quality also affects the subsequent construction quality, there is a risk of hole misalignment, therefore, the market has spawned road surface drilling machines.
