Problems solved by technology

However, this has some problems: Since there is no surrounding friction force by filling the pile with soil instead of cement, the allowable stress of the pile is easy to waste, and reinforcement work (especially central reinforcement) is difficult
However, this method also has some problems in terms of construction cost and availability

Embodiment Construction

[0042] Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0043] Fig. 2 is a cross-sectional view showing moment variation when the structure is loaded.

[0044] As shown in Fig. 2(a), along the direction indicated by the arrow, the load is applied to the structure from the structure itself to the center of the structure.

[0045] However, when a separating force 9 is applied on one side of the structure, besides the load of the structure, a moment of rotational force is generated respectively.

[0046] Therefore, as shown in Figure 2(c), when the separation force 9 is applied under the state of applying the structural load, the first moment of the rotational force is generated and a displacement is generated, so that an additional second moment is applied at this position until the displacement stop. As a result, the structure is adversely affected.

[0047] Since the above-mentioned problems also ...

Abstract

Disclosed herein is a head-extended pile with inside and outside reinforcements for supporting load of a structure. The head-extended pile includes a reinforcement part with the same length or area extending right and left with respect to a diameter of the pile provided at the front end of the pile so that a supporting force of the pile is increased, and a durability of the pile is improved by hammering after drilled piling. When the head-extended pile is applied according to the present invention, it improves the stability of proof stress of the pile and construction workability, and better economic efficiency is expected.

Description

field of invention [0001] The present invention relates to a head out pile, and more particularly to a head out pile having enhanced support capability for structural loads. The present invention also relates to a head extension pile with internal and external reinforcements for providing a method of pile construction ensuring stability, construction workability and economic efficiency when constructing piles. Background technique [0002] When building a building or a structure, depending on ground conditions or loads of the building or structure, foundations are usually constructed to reinforce the ground so that the building or structure can be stabilized on the ground. Construction of shallow or deep foundations can be done based on various conditions such as structural loads. A shallow foundation is a foundation with a penetration width ratio lower than 1, while a deep foundation is a foundation with a penetration width ratio higher than 1. In the case of shallow foun...
