Bored pile construction method suitable for tilt hard rock section
The invention belongs to the technical field of foundation pit construction, and particularly relates to a bored pile construction method suitable for a tilt hard rock section. The invention provides the bored pile construction method suitable for the tilt hard rock section, in order to rapidly and accurately construct bored piles, ensure the construction progress and avoid the problem of tilt of the bored piles when constructing the tilt hard rock section; a method of interval construction is adopted, a rotary drilling rig and a geological drill are subjected to joint construction, a method for using the geological drill to construct stress release holes first and then using the rotary drilling rig to construct the bored piles is adopted to release the rock stress, and meanwhile, the constructed stress release holes play a guide role in the construction of the rotary drilling rig so as to avoid the hole misregistration during the construction of the rotary drilling rig. With adoption of the bored pile construction method, the construction progress is accelerated obviously, and the economic benefits are significant.
