Partially-prefabricated friction pile and construction method thereof
The invention relates to the technical field of architectural engineering, in particular to a partially-prefabricated friction pile and a construction method thereof. The partially-prefabricated friction pile comprises an upper pile body, a lower pile body and a separation formwork arranged between the upper pile body and the lower pile body. The upper pile body comprises a standard segment and a pile bottom segment. The lower pile body comprises a force transferring structural segment, a variable-section structural segment and a bearing structural segment which are sequentially connected from top to bottom. The standard segment and the pile bottom segment are both prefabricated prestressed reinforced concrete tubular piles. Standardized production of the friction pile is achieved, the labor intensity of construction personnel is lowered, and manufacturing cost is reduced. The upper pile body is arranged outside the force transferring structural segment in a sleeving mode. Due to the split design of the upper pile body and the lower pile body, the bearing performance of whole-pile-length pile side friction resistance and pile end resistance can be fully achieved, and the overall bearing capacity of the friction pile is improved. Under the action of identical upper loads, the needed pile length or pile diameter is smaller, settlement deformation of the pile top can be effectively controlled, then the engineering cost of the friction pile is reduced, and social resources are saved.
