Problems solved by technology

[0002] In the prior art, the foundation of the new construction or the construction site of the structure is poor, which leads to the failure of normal construction by conventional piling equipment. It cannot be carried out normally; also when the construction site and space are limited in the reinforcement project, large-scale construction equipment cannot be used for construction, and small-scale equipment is used to drive steel pipe piles with small pile diameters, and the bearing capacity of the pile body cannot meet the project quality requirements, resulting in project not working properly

Embodiment 1

[0015] Embodiment 1: as figure 1 and figure 2 As shown, a steel pipe grouting pile includes a steel pipe pile body 1 , the bottom of which is tapered, and several through holes 2 are evenly arranged on the side wall of the steel pipe pile body 1 .

[0016] The diameter of the steel pipe pile body 1 is 50-150mm.

[0017] The steel pipe pile body 1 is a thin-walled steel pipe pile.

[0018] The through hole 2 is a candied fruit-shaped through hole.

Embodiment 2

[0019] Embodiment 2: A steel pipe grouting pile, comprising a steel pipe pile body 1 , the bottom of the steel pipe pile body 1 is conical, and several through holes 2 are uniformly arranged on the side wall of the steel pipe pile body 1 .

[0020] The diameter of the steel pipe pile body 1 is 50-150mm.

[0021] The steel pipe pile body 1 is a thin-walled steel pipe pile.

[0022] The through hole 2 is a Z-shaped through hole.

Embodiment 3

[0023] Embodiment 3: A steel pipe grouting pile, comprising a steel pipe pile body 1 , the bottom of the steel pipe pile body 1 is conical, and several through holes 2 are uniformly arranged on the side wall of the steel pipe pile body 1 .

[0024] The diameter of the steel pipe pile body 1 is 50-150mm.

[0025] The steel pipe pile body 1 is a thin-walled steel pipe pile.

[0026] The through hole 2 is an S-shaped through hole.

[0027] To sum up, the steel pipe grouting pile of the present invention opens holes on the side wall of the thin-walled steel pipe pile, and then uses pressure grouting equipment to inject chemical grout into the soil around the steel pipe pile through the openings in the side wall; the grout itself It has good strength, and can also be mixed with the soil around the pile body, and undergo physical and chemical reactions to form a reinforced soil with high strength; the grout and reinforced soil form a large hard block around the grouting hole body,...

Abstract

The invention discloses a steel pipe grouting pile. The steel pipe grouting pile comprises a steel pipe pile body, and the bottom of the steel pipe pile body is in a conical shape; a plurality of through holes are evenly formed in the side wall of the steel pipe pile body; according to the steel pipe grouting pile, holes are formed in the side wall of the thin-wall steel pipe pile, and a pressure grouting device is used for injecting chemical slurry into soil surrounding the steel pipe pile body through the holes in the side wall of the pile body; the slurry has the good intensity and meanwhile can be mixed with the soil surrounding the pile body to have the physical and chemical reaction, and reinforced soil with the higher intensity is achieved; a hard block body in the large size is formed surrounding the grouting holes through the slurry and the reinforced soil, a composite pile body is formed through the hard block body and the steel pipe pile body, the expanded rough pile body surface is formed, and the pressure-resisting and pulling-resisting bearing capacity of the steel pipe pile can be greatly improved; and meanwhile, the large hard block body forms effective lateral support on the large, long and thin steel pipe pile body, whole unstability of the pile body can be prevented, and therefore the bearing force of the pile body can be indirectly improved.

Description

technical field [0001] The invention relates to the technical field of steel pipe piles, in particular to a steel pipe grouting pile. Background technique [0002] In the prior art, the foundation of the new construction or the construction site of the structure is poor, which leads to the failure of normal construction by conventional piling equipment. It cannot be carried out normally; also when the construction site and space are limited in the reinforcement project, large-scale construction equipment cannot be used for construction, and small-scale equipment is used to drive steel pipe piles with small pile diameters, and the bearing capacity of the pile body cannot meet the project quality requirements, resulting in project cannot proceed normally. Contents of the invention [0003] The object of the present invention is to provide a steel pipe grouting pile with small diameter, light weight, low manufacturing cost and large bearing capacity. [0004] The technical ...
