Problems solved by technology

[0003] The upper soil resistance of the artificial excavated pile on the undisturbed soil foundation is small, and it is easily disturbed by the horizontal force, resulting in a large bending moment, resulting in a large displacement of the upper part of the artificial excavated pile

Abstract

The invention provides a manual hole digging pile, and relates to the field of electric power engineering. The manual hole digging pile comprises a body and wing plates. The body is columnar, one end of the body is provided with at least two wing plates, the wing plates are arranged on the side walls of the body, the top faces of the wing plates are flush with the end face of the body, and the wing plates stretch in the length direction of the body. The manual hole digging pile and a construction method of the manual hole digging pile have the advantages that the diameter and the burial depth of the manual hole digging pile are reduced, and structural materials are saved.

Description

technical field [0001] The invention relates to the field of electric power engineering, in particular to a construction method for manual hole-digging piles. Background technique [0002] Ordinary manual hole-digging piles are one of the commonly used foundation types for transmission line towers in mountainous and hilly areas. This type of foundation belongs to the undisturbed soil foundation. Instead of large excavation, concrete retaining walls are used for support, and then manually excavated to the designed buried depth. Finally, the soil model is used to form the foundation geometric size model, and the reinforcement cage is lowered and concrete is poured to form it. [0003] The upper soil resistance of the artificial excavated pile on the undisturbed soil foundation is small, and it is easily disturbed by the horizontal force, which produces a large bending moment, resulting in a large displacement of the upper part of the artificial excavated pile. For this reason...
