Description

[0001] The present invention relates to a device for dismantling wire for pile lifting,

The present invention relates to a device for dismantling a wire for lifting a building file, and more particularly to a device for dismantling a wire for use in lifting a file during construction of a file, .

Generally, construction will be done to reinforce the soft ground or to lay the pile on the ground for the foundation work of the building structure.

In embedding files in the ground, a method of directly installing the file on the ground and a method of embedding the file by excavating the ground are used. Recently, the ground which can be constructed by minimizing the influence of work environment such as noise and dust is excavated A method of embedding a file is widely used.

The method of excavating the ground by piercing the ground with the screw by using the perforating equipment and filling the pile with the pierced ground is used to prevent the pierced ground from collapsing. .

Then, when the loaded file is picked up and inserted into the casing, the ground can be safely buried without collapsing.

In order to insert the file into the casing, the loaded file is lifted and inserted into the casing. In the lifting of the file, the file is lifted mainly by the choking method.

A choking method is a method of lifting a wire to a file by lifting the wire to the outside of the file and lifting the wire to insert it into the casing.

At this time, as the file is inserted into the casing, the lifting wire is drawn into the casing and stuck between the casing and the file.

When file embedding is completed, the casing is pulled out and removed. If stiction occurs between the casing and the file as described above, pulling becomes difficult, and when the casing is pulled out, the file is also pulled together.

In order to solve the above-mentioned problem, in the prior art 1 (Korean Patent No. 10-1656696), when a file is buried in a casing using a ring-shaped ring, So as to be disassembled.

However, in the prior art document 1, it is formed as an integral ring, and it is necessary to lift the file before lifting the cable so that it is positioned lower than the wire at all times before inserting it into the casing and to move the file upwardly after the file is buried A problem arises.

In particular, when the length of a file protruding upward from the ground is long, it is necessary to move it to the top of the file to separate it, thereby increasing the fatigue of the operator and delaying the construction time.
