Description
Technical Field
The invention relates to the field of reaming pile construction, in particular to a hydraulic reaming circulation drilling machine and a reaming pile construction method thereof.
Background
Along with the development of modern construction in China, high-rise and super high-rise buildings in engineering construction are more and more, and the requirements on the bearing capacity and the construction technology of a pile foundation are higher and higher. The single pile bearing capacity can be greatly improved by implementing reaming construction on the pile foundation, and the construction cost is saved, so that various pile foundation reaming technologies and corresponding equipment appear in the field of pile foundation construction. The existing pile foundation reaming technology can be divided into tamping and expanding, exploding and expanding, manual hole digging and bottom expanding, hole expanding drill bit bottom expanding and the like according to the reaming principle. In these bottom expanding methods, the reaming method of the reamer bit has a wider application range than other reaming methods, and the reaming quality is better and more advanced, and accordingly, the reamer bit has the following three methods: squeezing and expanding, drilling and expanding, and rotary drilling and expanding (hydraulic).
In the squeezing and expanding technology, after conventional drilling is finished, squeezing and expanding equipment is put in, a squeezing and expanding arm is opened by a hydraulic cylinder to form an expanding branch in a hole, if a disc is to be formed, the squeezing and expanding arm needs to be retracted after primary squeezing and expanding, the squeezing and expanding arm rotates a certain angle and then squeezing and expanding are carried out, and a disc-shaped expanding cavity is formed after the steps are carried out for many times. The squeezing and expanding mode is from the beginning of double-arm unidirectional squeezing and expanding to the three-branch bidirectional squeezing and expanding cast-in-place pile in recent years. The drilling and reaming technology is improved on a drill bit of a conventional positive and negative circulation rotary drilling machine, so that the drilling and reaming machine has a reaming function. The existing reaming bit in the drilling and expanding technology is in a mechanical opening mode, and the common opening mode comprises a hole bottom pressing opening mode and a reverse opening mode. The bottom hole pressing method is that after the hole expanding drill bit is pressed to the bottom hole from the lower part, the hole expanding drill bit is pressed to open the hole by the self weight and the upper part of the drilling tool, and hole expansion is carried out at the bottom hole. The reverse rotation opening mode is that the blades of the reamer bit are folded in when the reamer bit rotates forwards, and the blades are opened in a mechanical mode when the reamer bit rotates reversely, so that the reamer bit can be reamed at the specified hole depth. The typical rotary drilling and reaming technology is an AM (amplitude modulation) construction method (rotary drilling and bottom-enlarging bored concrete pile), which is generated in Japan, and after the conventional straight hole is drilled, the rotary drilling machine provided with the reaming bit is adopted, and the rotary drilling and reaming are realized by opening the reaming bit while rotating at the specified hole depth in a hydraulic control mode. The above-mentioned various reaming techniques have certain drawbacks in reaming capability, stability and reliability of reaming, and construction efficiency, respectively.
