One end of the medium hitting body (7) is adhered and fixed to the core body (5 '), and the other end thereof is vertically downward. The tip of the other end is formed in a cylindrical shape or a prismatic shape, and can be formed in another shape. The medium hitting body (7) is slightly longer than the wedge body (6) formed simultaneously with the core body (5 '), and is configured to have a suitable size. For example, by pressing the core body (5 '), the intermediate hit body (7) moves downward, that is, toward the tip of the civil engineering pile body (1), and passes through the joint pile body (2'). Then, the core body (5) of the leading pile body (2) is pressed. The core body (5) in the leading pile body (2) is moved in the tip direction by the pressing of the middle hit body (7),
The wedge body (6) fixed to the core body (5) is projected outward from the opening (4), and the wedge body (6) provided in the core body (5 ') is also provided. It protrudes outside. The medium hitting body (7) functions in this way. Even when the joint piles (2 ') are connected, the same operation is performed. In addition, this medium hitting body (7)
Are not provided on the core body (5) mounted in the leading pile body (2).

(8) is a wedge guide pocket fitting. This wedge guide pocket metal fitting (8) is configured such that the outer surface is inclined in the direction of the open end, only two surfaces are open, and a slight locking portion is provided on the front open end side. It is provided and configured. The wedge guide pocket fitting (8) thus configured is provided with an opening (4) provided on each side wall of the leading pile (2) and the joint pile (2 ').
It can be attached and fixed to. This wedge-shaped guide pocket fitting (8) is slightly large and small.
Depending on the height of the opening (4), there is a slight change in the size in which it can be mounted. That is, the wedge body guide pocket fitting (5) in which the long end of the wedge body (6) fixed and attached to the core bodies (5) and (5 ') has the shorter end of the same wedge body (6) incorporated therein. This is because the long tip of the wedge body (6) is mounted so as to be stored in the built-in wedge guide pocket metal fitting (8) without conflicting with 8). The wedge guide pocket fitting (8) provided in the opening (4) as described above allows the wedge (6) to easily open the opening (4) when the core bodies (5) and (5 ') are pressed. From the ground, that is, into the soil. The wedge guide pocket fitting (8) performs such a function, and at the same time, usually, the tip of the wedge body (6) touches the bottom surface of the fitting (8), so that the core body (5) (5 ′). ) Also has a function of preventing falling.

(9) is a notch. This notch (9)
Are displayed in this embodiment. The notch (9) is provided when the core bodies (5) and (5 ') are formed in a prismatic shape (especially a square shape) (FIGS. 3 and 4). By providing this notch (9) in the core body (5) (5 ′), the core body (5) (5 ′) and the inner surface of the lead pile body (2) and the joint pile body (2 ′) are fixed. Is created. When this space is created, it is possible to insert a pipe into the civil engineering pile main body (1), and thereby, for example, cement, Alternatively, water glass or the like can be injected. By doing this,
The pile body (1) for civil engineering work can be more firmly fixed in the soil. The notch (9) is provided with a core body (5) in order to have such a function.
(5 '). This is the same when the leading pile body (2) is used alone as a civil engineering construction pile.

The core body (5) thus configured

Due to the friction between (5 ′) and the piles (2) and (2 ′) and the locking action of the wedges (6), they do not drop any more in normal times. When the core bodies (5) and (5 ') are installed, it is necessary to prevent the wedge body (6) from swinging. Since the wedge body (6) is somewhat long and swings, there is a surface which is difficult to be attached to the leading pile body (2) or the joint pile body (2 '). Therefore, in order to prevent the wedge body (6) from swinging, the core bodies (5) and (5 ') are attached to the leading pile body (2) or the joint pile body (2') before the wedge bodies (6). The wedge body (6) can be prevented from swinging by attaching the wedge body (6) swing prevention member formed of a simple synthetic resin material to a plurality of suitable locations. Thereby, the core bodies (5) and (5 ') can be easily fitted to the leading pile body (2) or the joint pile body (2').

The pile for civil works has no effect.
By pressing the core body (5) (5 '),
It comes off the wedge body (6) and is stored in the pile body (2) (2 '), and in some cases, it is fixed by concrete or the like. Since the wedge body (6) anti-swing member simply serves to prevent the wedge body (6) from swaying, it does not require a strong member.

The civil construction pile according to the present invention thus configured is used as follows. It is also possible to use only the leading pile (2) as long as it is used in a simple place. In this case, the core body (5) is pierced into the soil from the tip direction of the leading pile body (2), the piercing is stopped at a necessary limit, and then the core body (5) is pressed by another member. In 5), the wedge body (6) protrudes outside (in the soil) at the same time as it moves in the tip direction, and is inserted into the soil diagonally. It may be performed after attaching the wedge guide pocket fitting (8) to the opening (4) in advance. This may be sufficient for convenience, but this is not sufficient in normal cases. It is necessary to drive civil engineering piles into deeper soil. For example, when a large strength is required, such as for earthquake resistance or revetment, the leading pile (2) alone cannot be used for durability. For this purpose, the lead pile (2) is first driven into the soil in advance, and then the required number of joint piles (2 ')
Connect and go. After the connection to the required depth is completed and the driving to the required depth is completed, the core body (5 ') is pressed with another member or another component prepared for this civil construction pile. I do. As a result, the core body (5 ') moves toward the tip of the civil engineering work pile, and the core bodies (5) and (5') are sequentially moved. By doing so, the wedge bodies (6) of the core bodies (5) and (5 ') protrude outside (in the soil) and are in a state of being rooted. The pile for civil engineering work of the present invention is used in this manner.

[0020]

According to the present invention constructed as described above, the thickness of the wedge body attached to the core body can be reduced by a certain amount, and the symmetrical corners at the four corners of the base of the core body can be reduced. The wedges are symmetrically displaced from each other, so that they can receive the stability of force, and also stabilize the civil engineering work piles in the soil, prevent shaking, and prevent them from floating. Then, it can be fixed firmly in the soil to prevent the danger of underground construction. Also, since the present invention is suitable for mass production,
It can be supplied economically at low cost. It has such an effect.
