Description

Wall Pile {WALL PILE}

The present invention relates to a wall pile, and more particularly, to a wall pile applied to the wall and the order structure.

In general, when you sell foundations and tunnels, you can use it as a water barrier to prevent ground from falling around or on the ceiling when you sell foundations and tunnels, and for drainage in underwater construction, depending on the type of material. Divided into concrete slab and steel slab.

Wood board piles are mainly used for temporary provisional equipment, and steel board piles are used for weak cases as wooden board piles, and they are also used as permanent structures like reinforced concrete piles.

Currently, wooden board piles are used to prevent soil from collapsing in tunnel construction or subway construction. Steel sheet piles are used to prevent accidents in foundation works, and for permanent structures, they are used for protection and quay walls.

Reinforced concrete piles are used as permanent structures instead of steel sheet piles. Recently, prestressed concrete pile piles are also being used.

However, these conventional problems have the following problems.

First, when applied to the earth wall and the order structure using a steel sheet pile made of steel, the durability and environmental problems of the structure due to corrosion occurs.

In other words, the steel sheet pile made of steel is exposed to the front surface of the steel sheet pile in the air as it is, the corrosion occurs, thereby damaging the environment and aesthetics of the installation area and has a disadvantage that adversely affects the durability of the product.

In addition, when the general steel sheet pile is used as the wall of the wall, there is a disadvantage in that a separate device is required or difficult to use due to the lack of a lot of cross-section stiffness compared to the concrete sheet pile.

On the other hand, in the case of the existing concrete slab pile does not require a separate device because the rigidity is large, but there is a disadvantage in that the degree of orderability and continuity is less dense than the steel sheet pile in the connection.

The present invention is to solve the above-mentioned problems, by combining the stiffness and wall continuity (connector, grouting groove), which is an advantage of the steel sheet pile to the concrete pile pile to provide a wall pile that combines both high stiffness and continuity and continuity There is a purpose.

In order to achieve the above object, the present invention includes a concrete wall having a hollow portion for maximizing bending performance therein as a substantially rectangular shape; Transverse reinforcing bars disposed in the circumferential direction inside the concrete wall; Longitudinal reinforcing bars arranged in a direction orthogonal to the transverse bars; At least one grout groove formed on an outer surface of the concrete wall; It is provided with a wall pile, characterized in that it comprises a; connector provided for connecting to the neighboring wall pile.

The present invention can secure a large rigidity through the concrete wall, and can also provide a wall pile that can secure the degree of orderability and continuity through the connector and grouting groove which is steel.

In particular, when connecting as a continuous wall, the connector is not exposed can effectively solve the durability and environmental problems of the structure due to corrosion of the steel.

At this time, the connector (5) is a steel material, the reinforcement 500 is installed to be exposed to the surface of the grout groove (4) of the concrete wall (1); A hook-shaped connecting portion 510 integrally formed with the reinforcing member 500 for connection as a continuous wall with a neighboring wall pile; The reinforcement member 500 includes a shear connector 520 to be fixed to the concrete wall 1.

In addition, the reinforcement 500 forms a 'V' shape in cross section and the connection portion 510 forms a round hook shape.

The operation of the present invention configured as described above is as follows.

When applied to the wall and the order structure using a steel sheet pile made of steel, the durability and environmental problems of the structure due to corrosion occurs.

In addition, when the general steel sheet pile is used as the wall of the earth wall, the stiffness of the cross section is much shorter than that of the concrete sheet pile, so that a separate device is required.

On the other hand, in the case of the existing concrete slab pile, the rigidity does not require a separate device, but in the connection portion 510 is less dense than the steel sheet pile has a disadvantage of lowering the orderability and continuity.

However, the wall pile according to the present embodiment is not only easy to assemble the continuous wall by the connector (5) made of steel, but also shows excellent ordering performance, and also exhibits great rigidity by the concrete wall (1).

Therefore, it is possible to provide a wall pile having both high rigidity as well as both orderability and continuity.
