Embodiment 1

[0073] A post-grouting pile foundation, including a grouting port 1, and also includes a pile foundation pipe 4 and a rotating intermediate body 2, one end of the rotating intermediate body 2 communicates with the grouting port 1, and the other end of the rotating intermediate body 2 is connected to the pile foundation The pipe 4 is connected, and pile foundation holes 41 are distributed on the outside of the pile foundation pipe 4 .

[0074] Such as Figure 4 with 5 As shown, the pile foundation pipes 4 are all columnar in shape, and pile foundation holes 41 are uniformly arranged on the outside of the columnar pile foundation pipes 4. The pile foundation structure itself greatly improves the success rate of one-time installation of the pile body and does not require rework.

[0075] A grouting method for a post-grouting pile foundation, comprising the following steps:

[0076] A, construct a kind of back grouting pile foundation described above;

[0077] B. Drive the pil...

Embodiment 2

[0084] Such as Figure 6-8As shown, a post-grouting pile foundation includes a grouting port 1, and also includes a pile foundation pipe 4 and a rotating intermediate body 2. One end of the rotating intermediate body 2 communicates with the grouting port 1, and the other end of the rotating intermediate body 2 is outside It communicates with the pile foundation pipe 4, and pile foundation holes 41 are distributed on the outside of the pile foundation pipe 4.

[0085] The pile foundation pipe 4 is flat, and the flat pile foundation pipe 4 is not easily deformed, and the force is balanced, and it is not easy to drift and sink. Such as Figure 7 As shown, circular arc bodies 44 are evenly distributed on the outer side of the pile foundation pipe 4, and pile foundation holes 41 are distributed on the section 45 at the junction of adjacent circular arc bodies 44, and the slurry enters the pile foundation pipe from the grouting port 1 4, following the rotation of the pile foundati...

Embodiment 3

[0095] A kind of post-grouting pile foundation of the present embodiment, compared with embodiment 2, such as Figure 9 As shown, the difference is that the rotating intermediate body 2 is a bearing 5, one end of the bearing inner ring 51 communicates with the grouting port 1, the other end of the bearing inner ring 51 is connected with the pile foundation liner 3, and the bearing outer ring 52 is connected with the pile foundation Tube 4 communicates.

[0096] A grouting method for a post-grouting pile foundation, comprising the following steps:

[0097] A, construct a kind of back grouting pile foundation described above;

[0098] B. Drive the pile foundation into the position of the prefabricated pile, and connect the grouting port 1 with the grouting pipe;

[0099] C. Grouting into the grouting port 1 through the grouting pipe;

[0100] D. The slurry enters the pile foundation pipe 4 through the grouting port 1 and the bearing 5;

[0101] E. Due to the impact of the sl...

Abstract

The invention discloses a post-grouting pile foundation and a grouting method thereof, and belongs to the field of construction. The post-grouting pile foundation comprises a grouting port, a pile foundation pipe and a bearing; one end of the bearing communicates with the grouting port; the other end of the bearing communicates with the pile foundation pipe; pile foundation holes are distributed in the outer side of the pile foundation pipe; a dividing strip is arranged on the inner side of the pile foundation pipe; and an included angle is formed between the dividing strip and the vertical direction. The post-grouting pile foundation further comprises a pile foundation liner; pile foundation liner holes are formed in the outer side of the pile foundation liner; the pile foundation liner is columnar; the pile foundation liner holes are uniformly formed in the outer side of the columnar pile foundation liner; the pile foundation pipe is columnar; and the pile foundation holes are uniformly formed in the outer side of the columnar pile foundation pipe. The post-grouting pile foundation and the grouting method of the post-grouting pile foundation solve the problem that the supporting force of a pile foundation in the prior art is not sufficient. The post-grouting pile foundation is more stable, and can meet the requirement of a solar photovoltaic cell panel on the supporting force.

Description

technical field [0001] The invention relates to the construction field, in particular to a post-grouting pile foundation and a grouting method thereof. Background technique [0002] The cost of power transmission in the remote areas of Northwest my country is high and the power supply is insufficient, but the sunshine time is long all year round. The combination of solar energy and traditional power transmission is often used to supply power to local residents. A large number of solar photovoltaic panels need fixed support. The area of ​​solar photovoltaic panels Large, high cost, high load-bearing requirements, but the bearing capacity of conventional piles is limited. The existing treatment method is to consolidate the pile foundation to increase the bearing capacity of the pile and reduce the deformation and settlement of the pile. Solid square piles are used to support solar photovoltaic panels. There is a conduit in the center of the square pile. Concrete is injected fro...
