Abstract

The invention discloses a miniature inclined single pile structure. The miniature inclined single pile structure comprises a foundation, and the foundation is provided with a single pile hole; the single pile hole is inclined to a vertical plane; a miniature single pile is poured in the single pile hole and internally provided with tower leg angle steel; the tower leg angle steel penetrates into the miniature single pile, and the miniature single pile is parallel to the axis of the tower leg angle steel; by improving the line tower foundation, a bearing platform can be removed, construction procedures are simplified, and the construction cost is reduced; in addition, the inclined arrangement mode is adopted, and the tower leg angle steel can be conveniently and directly inserted into the foundation; the tower leg angle steel is adopted to be directly inserted into the foundation, so that the foundation connection structure materials are saved; and the force transmission path is simpleand direct, after inclined arrangement, the horizontal force action effect can be substantially reduced, and the rigidity of a pile body is improved.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a micro inclined single pile structure and a construction method thereof. Background technique [0002] The micro-pile is a thin pile with a diameter of 200-400mm that is drilled with an engineering geological drilling rig and the mud retaining wall. The concrete strength grade of the micro-pile body should not be lower than C15, the particle size of the crushed stone aggregate should be 10-25mm, and the grouting material can be cement mortar. The main reinforcement of the micro pile body section should not be less than 3, and the outer diameter of the reinforcement cage should be 40-60mm smaller than the designed pile diameter. The diameter of the commonly used main reinforcement is 12-18mm, the diameter of the stirrup is 6-8mm, and the distance between the stirrups is 150-250mm. Due to the small diameter of the pile, the micro pile foundation is arranged in groups of pi...
