In addition, the lower deck 116 may be further provided with a sprinkling pipe 152 for spraying water on the vent hole wall (10). The hydration heat generated from the pit hole wall 10 is discharged to the outside by the water sprayed from the water spray pipe 152 to prevent the pit hole wall 10 from being split by hydration heat after curing to some extent. This can prevent cracks from occurring. In FIG. 2, the sprinkling pipe 152 is shown as being located on the lower deck side, but the sprinkling pipe 152 is not only for the perforated wall located on the lower deck side, but also for all the perforated walls where the hardening process is performed three days before and after pouring. By spraying, it is possible to prevent the occurrence of cracks due to the heat of hydration. That is, since the hardening of the perforated wall is still progressing in the perforated wall located a few meters below the lower deck 116, the heat of hydration can be discharged from the perforated wall by spraying water through the sprinkling pipe 152. As a result, the durability of the porous hole wall 10 can be improved. Here, the water sprayed from the spray pipe 152 is sprayed at a pressure such that the perforated wall is not damaged.

In particular, since the cable 132 is not buckled and maintains a straight state in the direction of gravity, the work deck 110 does not swing in the excavation ground 1, and thus the cable drum 134 is driven. Along the vertical direction.

In addition, the winch hoisting slip foam 100 according to the present invention may be equipped with a guide anchor 136 to the excavation ground (1) in order to minimize the shaking of the cable 132 by an external force. As shown in FIG. 2, the guide anchor 136 has a through ring 136h formed at its distal end. Winch hoisting slip foam 100 according to an embodiment of the present invention, by inserting the cable 132 into the through ring 136h, it is possible to limit the movement of the cable 132 in the horizontal direction. Therefore, the work deck 110 may move only in the direction of gravity, and thus the inner circumferential surface of the abdominal cavity wall 10 is evenly formed.

Through ring 136h of the guide anchor 136, as shown in the enlarged view of Figure 2, by opening and closing can be formed, it is possible to facilitate the insertion and discharge of the cable 132. .

In addition, by further providing a drop preventing jaw 122 in the upper end of the skin plate 120, even if the cable 132 is broken it can be prevented that the work deck 110 falls. That is, the drop prevention jaw 122 is coupled to the upper end of the skin plate 120 to protrude in the radially outward direction of the skin plate 120, when the cable 132 is broken, the drop prevention jaw 122 and Interference may occur in the abdominal wall 10 to prevent the work deck 110 from falling.
