DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of burying a pile in the ground, and more particularly to a method of burying a pile in which the position of the top of the pile buried in the ground can be easily confirmed later. Things.

[0002]

2. Description of the Related Art In a conventional pile burying method of this kind, when a pile 1 is buried underground 2 as shown in FIG. 5, a sunk rod 4 having a cap 3 at a lower end is used. The pile 1 was cast in the underground 2. In addition, the depth adjustment of the pile 1 buried in the underground 2 was performed by previously applying a marking 5 to a predetermined position of the sinking rod 4 and confirming the marking at the level 6.

[0003]

However, after the above-mentioned conventional pile burial method is carried out, when the upper part of the pile 1 buried in the underground 2 is backfilled, the top 1a of the pile 1 is There is a problem that it is difficult to confirm the depth position of the top end 1a of the pile 1 because it is hidden inside. In particular, when the depth of impact of the top 1a of the pile 1 is shallow, it can be confirmed by inserting a timber or a reinforcing rod into the ground. However, when the depth of impact of the top 1a of the pile 1 is deep, Had a problem that could not be confirmed by human hands.

Therefore, when the top end 1a of the pile 1 is deeply hit, it is difficult to confirm the top end 1a of the pile 1 and, therefore, a large number of piles 1 buried in the ground 2 are difficult. Top 1 of
a becomes irregular, and when a foundation is constructed on these piles 1, there is a problem that reinforcement work of the piles 1 is required.

The pile embedding method according to the present invention is a completely new technique developed in view of the above-mentioned conventional problems. Particularly, even in the case of a pile having a deep hitting depth, the top position of the pile and its position are described. The purpose of the present invention is to provide a pile burial method that allows the depth to be constantly checked.

[0006]

The pile embedding method according to the present invention is a technique for fundamentally improving the above-mentioned conventional problems, and its gist is to bury a pile in the ground using a sunk rod. In the method, a rod is inserted into a hollow pipe attached along the axial direction of the sinking rod, and the lower end of the rod is brought into contact with the top end of the pile. This is a pile burying method characterized in that a sunk rod and a hollow pipe attached to the sunk rod are pulled up while being kept in contact with the top end of the pile.

[0007]

According to the pile burying method according to the present invention, as described above, a hollow pipe is attached to a sinking rod used when a pile is buried in the ground, and a rod is inserted through the hollow pipe. The lower end of the pile is brought into contact with the top of the pile, so when pulling up the sinking rod after the pile is hit, the rod can remain in the ground as it is. You can always check the depth.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, one embodiment of the pile embedding method of the present invention will be specifically described. FIG. 1 is an explanatory sectional view of an initial stage of implementing the method of the present invention, and FIG. FIG. 3 is a cross-sectional explanatory view in which a PC steel rod is inserted into a hollow pipe, FIG. 3 is a cross-sectional explanatory view in a state where a submerged rod is pulled up, and FIG. 4 is a cross-sectional explanatory view in a state where a PC steel rod is embedded in the ground.

In FIG. 1 to FIG. 3, reference numeral 11 denotes a sinking rod used when the pile 1 is buried in the ground 2, and a hollow pipe 12 is fixed to the sinking rod 11 in the axial direction. It is integrally attached via a tool 13. The lower end of the hollow pipe 12 is inserted into the cap 11a of the sinking rod 11, and the PC steel rod 14 inserted into the hollow pipe 12 is inserted.
Is in direct contact with the top end 1a of the pile 1.

The pile burying method of the present invention will be explained with reference to the drawings.
At the level 6 is confirmed, the burial of the pile 1 is stopped.
Next, the PC steel rod 14 is inserted into the hollow pipe 12 fixed to the sinking rod 11, and the lower end of the PC steel rod 14 is
Abuts on the top end 1a.

Thereafter, the submerged rod 11 and the hollow pipe 12 fixed to the submerged rod 11 are pulled up.
Is left in contact with the top end 1 a of the pile 1. When the submerged rod 11 and the hollow pipe 12 are lifted, the soil is naturally buried with the upper end of the PC steel rod 14 protruding to the surface of the ground. Can be displayed accurately.

Further, the depth indication 1 of the PC steel rod 14 is previously displayed.
4, the depth of the top end 1a of the pile 1 can be measured at the level 6, as shown in FIG. The hollow pipe 12 can be used by exchanging any one of the long and short hollow pipes corresponding to the depth at which the top end 1a of the pile 1 is struck. Further, the PC steel rod 1 used in the above embodiment was used.
No. 4 has a feature that it is not bent and can be smoothly inserted into the hollow pipe 12. However, as long as it is long, it is not limited to the PC steel rod 14, and any material and shape can be used. I can do it.

When the method of the present invention is carried out, the position and the depth of the pile 1 can always be accurately confirmed by the PC steel rod 14 abutting on the top end 1a of the pile 1 and standing on the ground surface. Therefore, the depths of a large number of piles 1 buried in the underground 2 can be easily adjusted.

[0014]

Since the pile burying method according to the present invention has the above-described configuration and operation, the position and depth of the top of the pile buried in the ground are always displayed and confirmed with a bar. I can do it. In addition, the method according to the present invention is easy to operate,
And it can be carried out regardless of the pile depth.

Further, by implementing the construction method according to the present invention, it is possible to prevent uneven tops of piles buried in the ground, thereby strengthening work due to uneven pile heads when constructing a foundation. Are not required.
