The present invention relates to a V-type casing type device for a drain type, in particular, to solve the drain phenomena and cutting phenomena due to the increase of disturbance area, the increase of the type energy due to the increase in the type energy, and the inflow of open soil in the casing. It relates to a V-type casing type device for a drain type that can be.

The drain method, which is a kind of soft ground consolidation method that is generally used, is a method of injecting drainage into the solid layer using heavy equipment from the soft layer to dewater the ground.

Such a drain method is required to secure the minimum supporting capacity required for entering heavy equipment as it is constructed using heavy equipment on the soft ground. Therefore, since most of the area lacks the supporting capacity of the soft ground, high-strength geotextiles are laid on the soft soil layer, and the required supporting power is secured by using soil, sand, or crushed aggregates. At this time, the thickness of the formed support layer is not constant and sometimes becomes thicker than necessary. In order to type the drain on the ground, the drain is inserted into the hollow casing, and a square anchor plate is attached to the iron plate so that soil or soft soil does not flow into the bottom of the casing. Such anchor plates have a much larger cross section than the casing to be easily fixed at the bottom of the soft layer after penetration. However, the penetration of the anchor plate is not easy, so a relatively large force is required, the equipment is enlarged, and the penetration may be in the form of a diagonal rather than a straight line. In addition, the anchor plate and the casing are simply adhered in a straight line so that the inflow of soft soil is easy, so that the drain is not fixed when the casing is pulled out, and it rises along the casing for a certain length (fiction) or the drain is cut. .

1 and 2, the drain type equipment generally used is a heavy equipment (fork crane) 100 that can type the drain 110 is mainly used. When the drain 110 is typed on the soft ground A ', the heavy equipment 100 is difficult to enter directly on the soft ground A', so that the bottom surface of the geotextile B ', the load distribution layer (mainly earth and sand) ( C ') and the drainage layer D' are installed, and then the drain 110 is inserted into the casing 130 having a cross section as shown in (a), (b) and (c) of FIG. Proceed with the process.

At this time, the casing 130 is not only constant in the site conditions, the thickness of the drainage layer (D ') and the soil layer (C') having a large penetration resistance, and the soil is not homogeneous, so the penetration is not smooth, thus requiring excessive force. And, due to this, the front part of the heavy equipment is excessively intruded or repositioned by adjusting its position.

In case of excessive type, the ground part is partially settled due to the partial load of the type device. Therefore, it is difficult to maintain the straightness of the drain due to the danger of conduction of heavy equipment and the bias of the equipment. In addition, in case of re-type, it is impossible to maintain an appropriate interval and work efficiency is deteriorated due to a delay in type time.
