Efficient anti-pulling anti-floating anchor rod for penetrating complex stratum and construction method thereof

Abstract

The invention discloses an efficient anti-pulling anti-floating anchor rod for penetrating a complex stratum and a construction method thereof. The efficient anti-pulling anti-floating anchor rod and an anchoring structure thereof are composed of an anchor rod main body tensile stress vertical rib, high-pressure high-strength dense cement mortar slurry, an anti-pulling type centering support, an annular water stop steel plate, a water-swelling type rubber sealing material and the like. The anti-floating anchor rod is excellent in anti-pulling performance, the construction efficiency of the anti-floating anchor rod pile can be improved by reducing the drilling depth of a drilled hole under the complex geological condition, the construction period is shortened, and the engineering cost is reduced; compared with a common anti-floating anchor rod pile, the anti-floating anchor rod pile has excellent durability; and the anchoring structure of the high-pulling-resistance anti-floating anchor rod is simple in preparation process, low in cost and high in adaptability in actual engineering construction.

Description

technical field [0001] The invention relates to the technical field of anti-floating anchor piles in construction engineering, in particular to a high-efficiency, pulling-resistant and anti-floating anchor for penetrating complex formations. Background technique [0002] In the construction process of construction projects, there are often geological conditions with a high groundwater level. When the height of the building itself is low or the self-weight is small, it is often difficult to offset the buoyancy brought by the groundwater. In this case, it is necessary to consider setting up Anti-floating measures. [0003] The anti-floating anchor pile is a kind of anti-floating structure of buildings that is widely used in the world at present, but the anti-floating anchor also has some disadvantages. Compared with uplift piles, due to their smaller hole diameter, the grouting material is mortar or cement slurry, the single pullout resistance is smaller, and the number of in...
