Good condition is created for next step secondary pile hole cleaning, accelerates integrated engineering construction speed, labor is saved for subsequent process
The input of the costs such as power, machinery, material.
Traditional construction technology is to be welded section by section in aperture, but the characteristics of deep hole large diameter drill hole pile is that steel reinforcement cage is long
Degree length, the quantity of merogenesis is more, and bar diameter is big to be needed to use sleeve connection, and installation difficulty is big, cannot can be made with multiplexing as welding
Surface construction, sleeve connection must obtain incremental, each sleeve can only be bit by bit tight inward, take it is especially more, at this
Being suspended in the boring mud among mud in the process can slowly precipitate, and the time is longer, and the boring mud of precipitation is more, and the difficulty of secondary pile hole cleaning is just
It is bigger, and the risk that steel reinforcement cage is buried is higher.
Present invention mainly solves steel reinforcement cage aperture jointing quantity is more, expend that the time is long, and bottom hole sediment thickness is difficult to
The problems such as control, and the construction of steel reinforcement cage can be started while drilling, the time of each cycle is shortened, largely
