Method for constructing long auger bored cast-with-pressure concrete uplift pile
The invention discloses a method for constructing a long auger bored cast-with-pressure concrete uplift pile. The method for constructing the long auger bored cast-with-pressure concrete uplift pile comprises the steps that the preparation for construction is made, paying-off for positioning is conducted, a drilling machine is prepared to work, a hole is formed by the drilling machine, drill lifting and fine aggregate concrete pouring are conducted at the same time, the hole is sealed and grouting is conducted, a steel reinforcement cage is inserted, and drilling tools and an earthwork are cleaned. The method for constructing the long auger bored cast-with-pressure concrete uplift pile has the advantages that concrete is pressed in a soil body and is located on the bottom and the side wall of the pile according to the specific grouting technique, the concrete and the soil body are glued into a whole, and in this way, the contact area between a pile body and the soil body is increased; compared with a traditional uplift pile, the uplift performance of the long auger bored cast-with-pressure concrete uplift pile is improved remarkably.
