Description

Casing air supply member and sand and/or gravel pile construction equipment including the same TECHNICAL FIELD [CASING AIR SUPPLY DEVICE AND SAND/GRAVEL COMPACTION PILE EQUIPMENT COMPRISING THE SAME}

The present invention relates to a casing air supply member and a sand and/or gravel pile construction (Sand/Gravel Compaction Pile, SCP/GCP) equipment including the same, and in more detail, a casing air supply member used to improve soft ground And it relates to a sand and / or gravel pile construction equipment comprising the same.

In general, construction equipment for improving soft ground includes a caterpillar vehicle equipped with a wide track, a leader installed in a vertical direction on one side of the caterpillar vehicle, ascending and descending in the longitudinal direction of the leader, and the soft ground at the tip. It consists of a configuration including a shoe and a probe for drilling, and a vibration hammer that is installed on the upper portion of the shoe and the probe to penetrate the shoe and the probe into the ground of the soft ground through vibration and generate a compaction action.

Therefore, the conventional construction equipment for improving the soft ground is by repeating the penetration or pulling of the shoe and probe into the ground due to the vibration and compaction that occurs as the vibration hammer is activated, and constructs a pile of reinforcing members made of gravel, etc. It will improve the soft ground.

The process of constructing the reinforcing member pile on the soft ground using conventional construction equipment is to form a perforated hole by penetrating construction equipment, that is, a shoe and a probe, on the soft ground, and reinforcing members such as gravel through the tip of the perforated hole. When the reinforcing member, such as gravel, is expanded by vibration in the perforated hole and then gradually withdrawn while starting the vibrating hammer, the reinforcing member pile is formed, thereby reinforcing the soft ground.

However, in the conventional construction equipment, a reinforcing member such as gravel is pulled downward at the tip of the perforated hole, and in the pulling-in process, it causes interference with the shoe and the probe of the construction equipment, so that smooth pull-in is not made. Of course, there is a problem that the construction equipment is not properly pulled out due to the reinforcing members drawn in the downward direction, resulting in poor workability.

In addition, problems such as damage to the construction equipment occurred as the shoe of construction equipment and the probe caused a collision with the falling reinforcing members.

In addition, the conventional construction equipment, when the shoe and the probe of the vibration rotating equipment are intruded or pulled out on the soft ground, the vibration rotating equipment is configured to be raised and lowered by hydraulic pressure, so that a separate hydraulic generating device and a hydraulic tank are installed. Since it must be provided, the overall facility is complicated, and when an abnormality in the hydraulic system line occurs, there is a problem that the construction is not smoothly performed.
