Embodiment 1

[0039] A steel pipe pile, such as figure 1 As shown, it includes a pile foundation main body 11, a spiral blade 6, an inner excavation cutter 61, and an outer excavation cutter 62. The formation is pushed through the rotation of the pile foundation main body 11, buried to a designated position (depth), and used as the foundation of a structure or a building. piles are used. In this embodiment, the term "building" mentioned below may also be represented as a structure. The pile foundation main body 11 used in this embodiment has a cylindrical shape (cylindrical shape here) extending linearly in the longitudinal direction.

[0040] Such asfigure 1 As shown, a continuous spiral blade 6 is provided on the outer peripheral surface of the front end of the pile foundation main body 11; in more detail, the outer diameter of the spiral blade 6 is larger than that of the pile foundation main body 11, and is fixed on the front end of the pile foundation main body 11. The outer peripher...

Embodiment 2

[0044] A steel pipe pile, such as image 3 As shown, when the construction requirements of steel pipe piles do not reach the design depth and the pile needs to be continued, the main body of the pile foundation is also included, and a hollow connector 13 is installed between the main body of the pile foundation 11 and the main body of the extended pile foundation 12. Connecting head 13 is externally connected with fixing structure 2 for fixing pile foundation main body 11 and extending pile foundation main body 12, and connecting head 13 is internally connected with supporting structure 3 for supporting and increasing compressive capacity, so the pile foundation main body is made 11 and the extended pile foundation body 12 are better fixed on the connector 13, and the fixed structure 2 relieves the expansion force of the cement slurry inside the connector 13 after solidification during the working process, reducing the internal pressure of the connector 13, and Through the com...

Embodiment 3

[0051] A steel pipe pile construction method, such as Figure 1-Figure 4 shown, including the following steps:

[0052] S1. The piling equipment with spinning driving device is in place, and the spinning and expanding head steel pipe pile with continuous spiral blades on the outer peripheral surface is installed on the spinning driving device of the piling equipment, aligned with the design position of the pile, and the steel pipe pile is adjusted. Verticality of pipe piles;

[0053] S2. The spinning driving device rotates to drive the steel pipe pile to rotate and drill down into the ground until the design depth required for the construction of the steel pipe pile is reached, and the piling equipment is separated from the steel pipe pile;

[0054] S3, judging whether to continue the pile, if not, then complete the construction of the steel pipe pile, if necessary, then enter step S4;

[0055] S4. Connect the steel pipe pile with the extended steel pipe pile body and fix it...

Abstract

The present invention relates to the technical field of steel pipe piles, in particular to a construction method of steel pipe piles, which aims to solve the problems in the prior art that steel pipe piles are not easy to be drilled into the ground and maintain the overall verticality of steel pipe piles. The key points of the technology include the following steps: S1. Install the spinning and expanding head steel pipe pile with continuous spiral blades on the outer peripheral surface to the spinning driving device of the piling equipment to adjust the verticality of the steel pipe pile; S2. Drive the steel pipe The pile rotates and drills down into the ground; S3. Judging whether the pile needs to be continued, and if so, proceed to step S4; S4. Install the extended steel pipe pile body on the spinning drive device of the piling equipment to drive the steel pipe pile Rotate with the extended steel pipe pile body and drill down into the stratum; S5. Determine whether to continue the pile, if necessary, repeat step S4 until the design depth required for the overall construction of the steel pipe pile is drilled. The invention can rely on the rotation of the helical blades to press into the ground, greatly speeding up the construction speed and helping to ensure the verticality of the steel pipe piles.

Description

technical field [0001] The invention relates to the technical field of steel pipe piles, in particular to a construction method for steel pipe piles. Background technique [0002] Steel pipe piles are currently widely used in the pile foundations of bridges, docks, houses, etc. from small to large buildings. It is very convenient for lifting, transportation or pile sinking. It is characterized by high bearing capacity. The current steel pipe piles It is generally hollow and cylindrical, and its construction method is to use piling equipment and piling hammers to drill into the ground. The problem with this construction method is that steel pipe piles are not easy to be drilled into the ground, which seriously affects the construction efficiency. [0003] At present, there are some patent records about steel pipe piles with spiral blades, and using the steel pipes for construction, such as the invention patent "Construction method of steel pipe piles and steel pipe piles" wit...
