Embodiment

[0020] Embodiment: the variable-diameter reinforced cage enlarged head anchor rod or pressure pile combined with the mixing pile or the rotary grouting pile, in the pile core or pile of the rotary grouting pile or the stirring pile including single pipe, double pipe method, and triple pipe construction The construction holes set at the lap joints or direct drilling, construction through reaming, lowering of variable diameter steel cages and tie rod assemblies, grouting or pouring concrete, composite anchors (or pressure piles) into piles.

[0021] Construction hole or direct drilling → reaming construction → lowering the variable diameter steel cage and tie rod assembly → grouting or pouring concrete → composite anchor (or pressure pile) into piles.

Abstract

The invention discloses a variable-diameter reinforcement cage expanded tip anchor rod anti-floating or compression pile combined with a mixing pile or a jet grouting pile. The variable-diameter reinforcement cage expanded tip anchor rod anti-floating or compression pile comprises the jet grouting pile or the mixing pile which is taken as a foundation, wherein a lap joint between the pile core ofthe get grouting pile or the mixing pile and the pile is equipped with a construction hole or is directly drilled with a hole; and a composite anchor rod or a compression pile which takes a variable-diameter reinforcement cage as a framework or is filled with concrete as a pile body is arranged in the hole. The expanded tip composite anchor rod (or the compression pile) which is formed by combining variable-diameter reinforcement cage expanded tip anchor rod preparation and mixing pile construction or high-pressure jet grouting pile construction also can be used as an anti-floating anti-pulling anchor rod or a compression pile foundation while existing anti-laying piles in row are matched as a seepage-proofing retaining wall.

Description

technical field [0001] The invention relates to the improvement of the stirring pile or the rotary grouting pile, especially the anti-floating or pressure-bearing pile (including the anchor rod) and the construction method of the variable-diameter reinforced cage enlarged head combined with the stirring pile or the rotary grouting pile. Background technique [0002] The jet grouted pile is an existing pile and has a ready-made construction method. The rotary grouting pile is drilled, the grouting pipe equipped with a special alloy nozzle is lowered to the predetermined position, and the cement slurry is sprayed into the soil at a high speed and horizontally through the special nozzle at the end of the drill pipe by a high-pressure pump. Cutting the soil layer, while the drill pipe is rotating at a certain speed (20r / min), while slowly lifting at a low speed (15-30cm / min), so that the soil and cement slurry are fully mixed and solidified, and the slurry of the high-pressure j...
