Description

Concrete file {Pile}

The present invention relates to a concrete pile, and more particularly, to a concrete pile having improved order and horizontal bending stiffness as a foundation pile for supporting an underground driveway, an alternate shore, a shore, a retaining wall, and an underground structure.

Generally, in case of construction work and foundation file construction at the construction site, the file is inserted into the ground and installed.

However, a conventional concrete file (here, a concrete file is a main material cement concrete and a little steel is mixed, hereinafter referred to as a concrete file) is constructed by closely connecting each file without a file connector, The injection material was put in order to prevent the invasion of water.

1 and 2 show an example of such a conventional concrete file.

That is, the conventional concrete pile 1 has grooves 2 on its outer periphery. When the piles 1 are inserted in a line on the ground, the grooves 2 and the grooves 2 meet to form one annular hole, and the injection material is placed in the annular hole.

However, since these files 1 are inserted separately on the ground, they may be horizontally inclined between the files. In this case, there is a problem in that the groove 2 and the groove 2 are not completely engaged with each other, so that leakage of the water between the piles 1 can not be completely prevented even if the grooves 2 are filled with the injection material.

In addition, since the conventional files 1 are inserted separately on the ground, there is no joint having rigidity connected to each other, so that the force to withstand the horizontal load is small, the twisting between the files can not be prevented, The bending stiffness is low.

A method for solving such a problem has been developed in Korean Patent Registration No. 10-0473375. This method uses a steel plate to interconnect the files.

However, the above method has a problem that a heavy steel plate is used and a grouting groove for a different order must be provided.

Therefore, it is possible to improve the horizontal load when the concrete piles are connected to each other by using a connecting pipe to reduce the weight and without providing a separate grouting groove without using a heavy steel lump, The development of a concrete file that can grout for the order was desperate.

SUMMARY OF THE INVENTION The present invention has been made in order to solve all of the above problems, and it is an object of the present invention to improve water repellency when concrete files are installed in contact with each other, And to provide a concrete file capable of preventing twisting between files.

Further, in the concrete pile according to the present invention, the grouting groove may be formed in one side of the connecting pipe, and may be a through hole, and a grouting groove through which the grouting injected to the connecting pipe can flow out is further provided .

Also, in the concrete pile according to the present invention, the connecting pipe insertion groove has a diagonal shape so that the connecting pipe insertion groove formed by the adjacent concrete piles has a rectangular cross-sectional shape And the connecting pipe has a rectangular pipe shape having a rectangular cross-sectional shape.

Further, in the concrete pile according to the present invention, the connection pipe insertion groove has a semicircular shape, and the connection pipe insertion groove formed by the adjacent concrete files has a circular cross-sectional shape, The tube is characterized in that it has the shape of a circular tube whose cross section is circular.

Also, in the concrete pile according to the present invention, the connecting pipe insertion groove has a diagonal shape so that the connecting pipe insertion groove formed by the adjacent concrete piles has a rectangular cross-sectional shape And the connecting pipe is formed of a diaphragm having a cross-sectional shape of a diagonal shape.

According to the concrete file according to the present invention, when concrete files are installed in contact with each other, water repellency can be improved, the force against the horizontal load of the files can be further increased, and the effect of preventing twisting between files .
