Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sheet pile construction apparatus for perforating and piling,

The present invention relates to a sheet file construction apparatus capable of simultaneously performing punching and piling operations, and more particularly, to a sheet file construction apparatus capable of simultaneously performing a punching operation of a file punch for inserting a file and a piling operation for inserting a file into a punch hole, And more particularly to a pile construction apparatus capable of simultaneously performing perforation and piling operations with excellent construction quality.

Generally, when reinforcing concrete structures or other buildings are built, PHC, steel pipe files or H beams are embedded at regular intervals on the ground to be excavated in order to solidify the foundations of foundation, The construction of such a file is very important in the construction of structures and buildings.

Piling construction method and excavation construction method are used as a method of constructing a file in foundation work. The installation method is to lift the hammer of the weight using the hoisting rope installed on the upper part of the riser installed vertically on the hoisting machine, to drop the hoisting pile, or to raise the hammer by using compressed air of the compressor, This type of construction method is a hammering method, and the use of the hammers is very limited due to the problem that the hitting sound and the vibration are largely generated when the top of the file is laid.

In the excavation method, a screw rod mounted on an auger machine is rotated to excavate a ground to form a pile hole, and then the screw rod is rotated in a reverse direction to pull the pile out of the excavated pile and insert the pile into the pile. However, when the screw rod is pulled out from the excavated pile, the conventional excavation method is less effective than the conventional pile construction method. However, when the screw rod is pulled out from the excavated pile, It is necessary not only to newly puncture the file hole due to the collapse of the file hole but also to increase the air by drilling the file hole and piling the file separately.

In addition, the punching of the pile of holes and the pile driving of the pile or casing are carried out separately, which not only complicates the construction work but also increases the air (construction period) and runs punching equipment and piling equipment together in the workshop. Which makes it difficult to efficiently use the workplace.

On the other hand, in recent years, a method of applying a sheet file (steel sheet pile) has been developed. The sheet pile has a trapezoidal shape in which the both ends of the sheet are open to the outside while the material is the main force and the cross-section has a substantially U shape, and both ends of the sheet file, which are opened toward the outside in a trapezoidal shape, As shown in FIG.

Accordingly, a plurality of sheet files may be installed on a ground in a straight line structure, or may be installed in a straight line, and may be installed in a type that is installed at a desired angle, or may be installed in a circular shape. The sheet pile is pressed into the ground by a noiseless vibration-free method mainly in roads, shore, harbor, and river works, such as when constructing concrete buildings or constructing continuous walls with water curtains and building bridges such as bridges and overpasses .

A conventional seat file paddle for this purpose is mounted on the end of a boom of a power shovel to be able to fix a seat file. A rotary frame is installed as a bearing housing at the lower end of a bracket mounted on a boom of a power shovel, And a chuck capable of clamping the sheet file at its lower end.

The above-described conventional vibro-lashing machine clamps the head of the sheet pile with the chuck, turns the power shovel to move to the pile position of the sheet pile, and manually aligns the lower end of the sheet pile Insert the sheet file by typing with the post-vibrator.

In the conventional hitching operation, a worker must manually perform a work of matching with the connecting portion of the preceding sheet file, and since the hitting is performed by vibrating the head portion of the sheet file, a defective operation of inserting the sheet file is inconvenient, There are inconveniences of taking out the file and adjusting it again, and also because the tableting work is proceeding from the head of the sheet file. Therefore, when the work place is equipped with a high-voltage line on the ground or an obstacle such as a bridge, There arises a problem that it is difficult to work due to noise vibration.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art,
