状でもよい。FIG. 1 is a simplified explanatory diagram showing one embodiment of the present invention, (1)
is a steel rod for impact or vibration transmission, and the one end (1,
a) is provided with a consolidation part (2) for compacting a mound (M) or soft ground on the seabed, and when the consolidation part (2) is placed on the seabed, the other end of the rod (1) Part (1b)
-C becomes exposed at least to the water surface. The other end (1h) of the rod (1) is connected to the crane ship (
It is suspended from a mound (M) on the ocean floor, supported by a lie 1 fu lobe (3) suspended from the leader (L) of S). In such a configuration, a hammer device such as a diesel hammer (H) installed in the rod (1) repeatedly hits or vibrates the lower striking plate (5) by hitting the leader rail (4) thereof. The C1 mound (lv'l) or soft ground is compacted or finished through the rod (1), and the rod (1)
A surveying ruler and work scaffolding tank corresponding to the height (
6) is arranged. The turret (6) is made of four pillars (7) with beams (8) and striations (9) arranged at appropriate intervals, and is a square-shaped turret as shown in the same figure (b). The shapes are not limited to rectangular shapes, but may be other shapes.
このような櫓〈６）を配置することにより、作業足場用
に利用できるばかり′Ｃなく、測定定規として用いうる
ので施工精度を高めることができる。By arranging such a turret (6), it can be used not only as a work scaffold, but also as a measuring ruler, thereby increasing construction accuracy.
なお、前記ディーゼルハンマー（Ｈ）は水面より上の位
置に取付けた方がより能率的であり、又、圧密部（２）

目潰しとすることもできる。It should be noted that it is more efficient to install the diesel hammer (H) above the water surface.
The central part of the structure has a structure that can be opened and closed, and the upper rod (
1) Aggregates such as sand and crushed stones are stored in the hollow part, and if necessary, the aggregates can be poured into softer submarine ground or the like than the central part to fill the hollow part.

A consolidation section (2) is provided, and the rod (1) is connected to the pile keeper.
(3') is supported in the vertical direction. At least the other end (1b) of the rod (1) exposed to the water surface
) with a diegel hammer (H) etc. installed on the leader <L) of the crane ship (S), or by applying vibrations to the mound (M) or G-type soft ground via the rod (1). A rod (1) for compaction or finishing.
As shown in Figure 2 (b), the surveying ruler/work scaffold tank (6') placed around the crane ship (6')
It has a C-shaped shape facing toward the turret (
6'), construction 'II! The compaction method can be carried out advantageously by increasing the i degree.
