Description

Civil engineering file {pile for public works}

The present invention relates to a civil engineering pile, and more particularly, a first pile portion which is installed perpendicularly to the ground, and is disposed inside the first pile portion, and the lower portion protrudes to the outside of the first pile portion by an external impact. By providing a second pile part installed in the ground, it can be installed without deformation on the ground, which can shorten the construction period according to the civil works, and also ensure stability, and provide a difficult construction such as a river pier or a harbor facility. It is about a civil engineering file that can be used.

In general, piles (piles, piles) used in civil works are installed to increase the strength of the foundation ground and to withstand the heavy loads placed on it when the foundation ground is weak. These piles are mainly made of wood, concrete and steel. The method of installing the pile (pile) as described above is to install on the ground immediately by applying an external impact of the pile (pile), and after laying the foundation support member made of a separate concrete in the ground The method of covering is used.

By the way, the method of hitting the ground just installed in the above method has the advantage that can shorten the working time, but there was a problem that the pile (pile) is not installed firmly, the pile (pile) formed with the foundation support member is the ground Excavation work, because it has to go through the work to fill the excavated ground again, there was a problem that takes a long time, and also, there is a problem that the ground is weakened due to the filling operation.

The present invention is devised to solve the conventional problems as described above, the object of the present invention is the first pile portion installed perpendicular to the ground, and the first pile portion is disposed inside the lower portion by the external impact By providing a second pile portion which protrudes out of the pile portion and is installed in the ground, it can be installed without applying deformation to the ground, which can shorten the construction period due to civil works, and also ensure the stability of rivers. It is to provide a civil engineering file that can be used for construction work such as bridge piers and port facilities.
