Rotary drill drilling cast-in-place pile construction method
The invention relates to the technical field of bridge pile foundation construction, in particular to a rotary drill drilling cast-in-place pile construction method. According to the rotary drill drilling cast-in-place pile construction method provided by the invention, a steel casing is divided into multiple sections; each steel casing section is mounted separately; all the steel casing sections are connected into a whole body in a pin connection manner, so as to form the steel casing, of which the length is sufficient to penetrate through the thickness of a silt clay layer or quicksand layer, so that the technical problem in the traditional construction methods that a pile foundation cannot achieve hole forming due to the fact that the steel casing sinks or a stratum encounters hole collapse during the drilling of the silt clay layer or quicksand layer and hole drilling construction cannot be carried out normally is solved; meanwhile, the steel casing with the wall thickness of 3cm is adopted, so that a greater pressure can be undertaken, and the problem that the steel casing is extruded to deform and even damaged due to too great internal and external pressure difference of the steel casing can be avoided; the wall thickness of the steel casing is relatively great, the structure is stable, the service life is longer, the utilization ratio of the steel casing is relatively high, and thus, the construction cost can be reduced.
