Description

Top file {Top base concrete}

The present invention is a top pile installed to reinforce the soft ground, and more specifically, insert the reinforcement inside the top pile body to strengthen the body itself and at the same time improve the shear force, the U-shaped used when lifting the top pile The rings do not fall out.

At the time when there were many sites available, there were many grounds with good bearing capacity and settlement characteristics, so it was not necessary to improve the soft ground or improve the bearing capacity and settlement characteristics.

However, with the development of the industry and the increase of the population, the ground having good soil characteristics is almost filled with structures, and nowadays, the use of soft ground such as reclaimed land or landfills with landfills is inevitable.

On the other hand, such a soft ground has a small bearing capacity and represents an unstable state, so ground subsidence and destruction may occur when constructing a structure.

Therefore, before constructing a structure on the soft ground, the ground must be reinforced according to the size and use of the structure.

On the other hand, the conventional method of reinforcing the soft ground is a concrete pile foundation method for reinforcing the foundation of the ground by embedding a concrete pile of 10-30m in the ground,

There is a mat method that reinforces the mat like a mesh on the soft ground by filling it with soil and filling it in between.

As shown in this paper, various soft ground reinforcement methods using top-shaped concrete piles are used.

Looking at the structure of a conventional top-shaped concrete pile belongs to the present invention as follows.

As shown in Figure 10, the conventional conventional fold pile 100, the upper end has a conical upper body 10, the lower end has a cylindrical lower body 20, the center of the U-shaped ring (50) ) Has an inherent shape.

The top-shaped concrete pile has a high bearing force because the bottom surface of the upper body is inclined at the same time as the bottom surface of the upper body and is inclined at the same time, thereby dispersing the material load acting from the top to the bottom.

On the other hand, the soft ground reinforcement method using the top-shaped concrete pile is a ground foundation method that is suitably used for the foundation work of small and medium-sized structures in which the bearing capacity of the ground is somewhat insufficient or the load is insignificant. The piles are piled into the ground, and the top-shaped concrete piles are connected by horizontal and vertical reinforcing bars, and rubble is filled between the top-shaped concrete piles to reinforce the soft ground.

On the other hand, the manufacturing process of the top file is as follows.

That is, after the top of the U-shaped ring 50 to protrude out of the mold in the shape of the top shape and curing the concrete in the mold, all the work is completed by removing the top-shaped concrete pile from the mold.

However, such a conventional top pile may cause the ring 50 to fall out when the top pile 100 is lifted or transported using the ring 50, or a broken part of the neck, which is the most vulnerable portion, may be broken. .

Therefore, in order to solve this disadvantage, the lower protective cap 40 is installed at the end of the top pile 100, and the neck protective cap 30 is integrally formed on the middle neck.

However, even if the lower protective cap 40 and the neck protection cap 30 is formed in this way, the present invention has been developed because there is still insufficient point to prevent the upper body of the top pile from being broken and the ring from being pulled out.

Although the present invention and its configuration are different, the background art
