Problems solved by technology

[0003] Traditionally, the anti-floating anchor rod body is grouted with cement slurry or cement mortar, which will consume a large amount of cement, which runs counter to the air pollution prevention and control policy that is increasingly valued, and after the anchor bar is placed in place after the hole is formed, if the grout is not injected in time, it will be easy. Cause hole collapse, may require secondary hole formation

Embodiment Construction

[0032] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the examples. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0033] Such as Figure 1~Figure 3 As shown, an anti-floating anchor pile device includes pile body 9, anchor bar steel bar 1, positioning bracket 2, graded crushed stone 3, foundation cushion 4, steel plate water-stop collar 5, concrete foundation 6, foundation surface Layer steel mesh sheet 7. In this embodiment, the pile body 9 has a diameter of 180mm and a length of 8m.

[0034] The pile body 9 is arranged in the borehole 10, the pile body 9 is a crushed stone concrete pile body, the anchor rod steel bar 1 is arranged in the pile body 9, the foundation 11 at the top of the bor...

Abstract

The invention discloses an anti-floating anchor rod pile. The anti-floating anchor rod pile comprises a pile body arranged in a drilled hole; the pipe body is internally provided with an anchor rod steel bar; a foundation cushion layer is paved on a foundation at the top end of the drilled hole; a concrete foundation is arranged on the foundation cushion layer; a foundation surface-layer steel barnet sheet is arranged at the top of the concrete foundation; the bottom end of the anchor rod steel bar extends to the bottom of the pile body; the top end of the anchor rod steel bar stretches out of the top end of the pile body and extends into the concrete foundation; the top end of the anchor rod steel bar is pressed on the foundation surface-layer steel bar net sheet; a steel plate water stopping sleeve ring sleeves a part, located in the concrete foundation, of the anchor rod steel bar; the pile body is internally provided with arch-shaped positioning brackets at intervals of pre-set height; arch bottoms of the positioning brackets are fixed with the anchor rod steel bar. The invention further discloses a construction method of the anti-floating anchor rod pile. The anti-floating anchor rod pile has the advantages of firm structure and convenience for construction; the pile body is prevented from hole collapsing in a pouring construction process; the anti-floating anchor rod pile has a seepage-proof effect and the use amount of cement is saved.

Description

technical field [0001] The invention belongs to the field of anti-floating anchors, in particular to an anti-floating anchor pile, and also relates to a construction method for an anti-floating anchor pile, which is suitable for the design and construction of anti-floating anchor projects. Background technique [0002] Anti-floating anchor rod is a kind of anti-floating measures for underground structures in construction projects. According to soil conditions, construction technology, pullout force requirements, etc., the common diameters of pullout anchors are 150mm, 180mm, 200mm, 250mm, etc., and the length of the anchors ranges from several meters to more than ten meters or even longer. [0003] Traditionally, the anti-floating anchor rod body is grouted with cement slurry or cement mortar, which will consume a large amount of cement, which runs counter to the air pollution prevention and control policy that is increasingly valued, and after the anchor bar is placed in pl...
