Description

FILE CONSTRUCTION APPARATUS}

One embodiment of the present invention relates to a pile construction device.

In general, structures for transmitting various loads applied to a building to the ground are called foundation structures, and the construction of foundation structures is collectively referred to as foundation construction. In foundation construction, if the ground has sufficient strength, the foundation structure can be built directly on the ground. However, if the ground is weak, the foundation structure is built on top of it by improving the ground or driving piles. The construction of such piles is very important in constructing structures and buildings.

Pile construction methods such as pouring construction method and excavation construction method are used in foundation construction. The pouring construction method is a method of pouring a pile into the ground while raising and lowering the hammer of a heavy body using a hoisting rope installed on the top of a leader installed vertically on a crane. In this construction method, the top of the pile is poured using a hammer. There is a problem in that a large hitting sound and vibration occurs during use.

The excavation construction method is used as an alternative to solve the problems of the tunnel construction method. Drilling work is performed to drill the pile hole using an auger screw installed on the leader of the pile driver. Once the drilling work through the auger screw is completed, the pile hole is drilled. The screw is reversely rotated to remove it from the excavated pile hole, and then the leader operates to lift the separately provided sheet pile (SHEEIT PILE) to prevent collapse, such as the collapse of the soil pile in the drilled pile hole. , the lifted sheet pile is buried in the drilled pile hole using a vibrator installed separately on the auger screw.

In addition, when the pile hole is drilled and the insertion of the sheet pile into the drilled pile hole is completed, the second pile hole is drilled in close proximity to the first pile hole for which the drilling has been completed, and the same process as above is performed, and this process is repeated. You can continuously insert sheet files while doing so.

However, according to this conventional excavation construction method, the drilling work using an auger screw, the lifting of the sheet pile using a leader, and the insertion work of the sheet pile using a vibrator are each performed separately, and are performed alternately and repeatedly to create one pile. The equipment became complex, requiring many operations and processes to drill holes and insert sheet piles, complicating construction work. Furthermore, it made it difficult to use the workshop efficiently, resulting in an increase in labor time, which not only increased construction costs but also lowered work efficiency.

In addition, it is common for 'ㄷ' shaped sheet piles opened to the right (type 1 sheet piles) and 'ㄷ' shaped sheet piles opened to the left (type 2 sheet piles) to be sequentially connected. After the insertion process was completed by fixing the type 1 sheet pile, the path that the leader or the car body had to move to place the type 2 sheet pile in its correct position was complicated, so there was a limit to increasing construction efficiency.

One aspect of the present invention can provide a pile construction device that can improve at least one of the efficiency and safety of construction and the stability and durability of the pile construction device.
