Problems solved by technology

[0002] During construction, in the process of foundation excavation, the most important process is to bury piles that can be integrated with the building being constructed. This pile is the key to the load-bearing and stability of the building. There are currently two types of ground piles, one It is a friction pile, and its construction generally adopts the practice of drilling pile holes first, and then binding steel bars to pour concrete. However, this method is cumbersome, and the construction period is long, time-consuming and laborious; Hollow steel fiber cement piles, but this kind of prefabricated piles are prone to damage due to the large force when they are drilled into the ground

Embodiment 1

[0034] The tapered metal ground pile of this embodiment refers to Figure 1-3, which is a vertical single-column structure, including an auger bit 1 and a cone 2, the large diameter end of the cone is connected to the power source input joint, and the auger bit 1 and the cone 2 It is made of metal material, the drill bit and the cone 2 are integrated by casting or welding, and the metal ground pile is not taken out after being driven into the ground, and it is directly used as a pile body;

[0035] The auger bit 1 has an inverted conical structure, and the helical blade 8 spirals up around the axis, and the outer diameter gradually increases with the helical rise, forming a smooth helical cutting curve, which is convenient for the helical cutting of the soil layer by the blade, and meets the needs of drilling conical metal ground piles , and can be stably combined with the soil layer, and have strong support for the supported buildings or other ground objects. The thickness of t...

Embodiment 2

[0040] The difference between the conical metal ground pile of the embodiment and the embodiment 1 is: referring to Fig. 4-6, the drill bit is a sharp drill bit 9, the drill bit and the cone 2 are cast or welded as a whole, and the cone 2 is directly connected to the input joint of the power source .

Embodiment 3

[0042] The difference between the tapered metal ground pile of this embodiment and embodiment 1 is:

[0043] The outside of the upper end of the cone 2, the outside of the upper end of the connecting cone 6 and the inside of the lower end are respectively provided with positioning blocks 4, each of which is arranged in two layers evenly. The block 4 is correspondingly dislocated and connected, and the positioning block 4 outside the upper end of the connecting cone 6 is connected with the corresponding dislocation of the positioning block 4 set by the power source input joint; a drill pipe is connected on the connecting cone 6.

[0044] The installation and construction method of the conical metal ground pile of the above embodiment comprises the following operations:

[0045] 1. The drill bit and the cone 2 made of metal materials such as steel or iron are integrated by casting or welding, or the drill bit and the cone 2 are cast or welded as a whole;

[0046] 2. Connect the...

Abstract

The invention relates to a conical metal ground pile and belongs to the ground pile structure technical field. The conical metal pile is characterized in that: the pile comprises a bit on the bottom of the pile and a cone with an upper end connected with an input connector of a power source, wherein, the bit and the cone are made of metal materials and are integrated into a whole by casting or welding, or the bit and the cone are integrally produced by casting or welding; and the metal ground pile is not taken out any more when the metal ground pile is driven underground, and is directly used as a pile body. The conical metal ground pile has the advantages of high mechanical performance, long service life, low cost, high working efficiency, flexible and simple and convenient assembly and so on, and is more widely used for the construction of a plurality of ground piles, ground anchors, and randomly-constructed ground piles, based on the use on an 'end-bearing pile' construction and a 'friction pile' construction during the building construction.

Description

1. Technical field [0001] The invention relates to a ground pile for construction, in particular to a conical metal ground pile, which belongs to the technical field of ground pile structures. 2. Background technology [0002] During construction, in the process of foundation excavation, the most important process is to bury piles that can be integrated with the building being constructed. This pile is the key to the load-bearing and stability of the building. There are currently two types of ground piles, one It is a friction pile, and its construction generally adopts the practice of drilling pile holes first, and then binding steel bars to pour concrete. However, this method is cumbersome, and the construction period is long, time-consuming and laborious; Hollow steel fiber cement piles, but this kind of prefabricated piles are prone to damage due to the large force when they are drilled into the ground. 3. Contents of the invention [0003] The purpose of the present ...
