Abstract

PURPOSE:To efficiently consolidate a sea bottom ground by means of a high head, by a method wherein a hollow rod, extending from a consolidating part placed on the sea bottom to a surface, is installed upright, and a hanging-down hammer is dropped from the surface within the rod to exert impact. CONSTITUTION:A hollow rod 1 is installed upright such that it extends from a consolidating part 2, brought into contact with a ground G, such as soft grounds under a surface, for consolidation, and is emerged from a water level, and a hammer 3 at the forward end of a wire hung down from a boom L of a crane ship S is dropped and raised within the rod 1. The hammer 3 is dropped along the rod 1 serving as a guide to compact a mound and a soft ground G at the sea bottom. This enables efficient compaction of the soft ground through provision of a high head.

Contents of the English 3rd Floor Building System 48 Amendment (2) Figures 3 and 4 will be added to the drawings. Description 1, Title of the invention 1, Compaction method for weak ground 2, Claims (1) A rod having a consolidation section at one end for compacting the ground, with the consolidation section placed on seabed ground; A method for compacting soft ground, which is characterized by compacting the ground to a desired strength or finishing it to a desired precision by applying impact or vibration with a hammer suspended from a wire from a crane or installed inside a rod. (2) A method for compacting soft ground according to claim (1), in which a hammer is dropped into the bottom of the hollow portion of the rod to apply impact or vibration. (3) A method for compacting soft ground according to claim (1), in which a hammer device is installed in the hollow part of the rod to apply impact or vibration. (4) A method for compacting soft ground according to claim (1), in which a hammer device is installed on the top of the rod to apply impact or vibration. 3. Detailed Description of the Invention The present invention relates to a compaction method for soft ground under water, such as submarine ground, and relates to an additional invention to the invention of Japanese Patent Application No. 1254958/1983. The applicant previously filed a patent application in 1983. No. 125495, the other end of a rod has a consolidation part for compacting the ground at one end, and the other end is exposed at least above the water surface when the consolidation part is placed on the seabed ground. Compact the ground to a desired strength by applying impact or vibration to the
Alternatively, a compaction method for soft ground has been developed which is characterized by finishing with arbitrary precision, and the present invention is a further improvement of this method. That is, in the above-mentioned construction method, the present invention provides a method in which, when applying a blow or vibration through the rod, a blow or ffi L is applied to the rod using a hammer suspended from a wire from a crane or installed inside the rod to tighten the ground to an arbitrary strength. It is characterized by being hardened or finished to desired precision. The present invention will be explained below with reference to the drawings. FIG. 1 is a simplified explanatory diagram showing one embodiment of the present invention, (1)
is a rod for striking or photographing and transmitting, and is hollow to the bottom (1C), and one end (1a) has a rod for compacting soft ground (G) or a mound (not shown) on the seabed. A consolidation section (2) is provided for this purpose. The consolidation part 2)
is placed on the seabed, the other end of the rod (1) (
1b) is arranged so as to be exposed at least to the water surface. Inside this other end (1b) is the boom of the crane ship (S) l)
Place the hammer (3) suspended by a wire on the bottom (1C).
This is a method of compacting the soft ground (G) or mound via the rod (1) by repeatedly dropping it until it hits or vibrates. At this time, the hollow part of the rod (1) serves as a guide when the hammer (3) falls and when it is pulled up, not only making it possible to perform compaction smoothly, but also allowing for a large head difference, making it possible to compact efficiently. . FIG. 2 is a simplified explanatory diagram showing an embodiment of the present invention.
) is a steel rod for impact or vibration transmission, and the one end (1
a) is provided with a consolidation part (2) for compacting the seabed land (M) or soft ground, and when the consolidation part (2) is placed on the seabed, the rod (1) The other end (1b
) are at least exposed to the water surface. The other end (1b) of the rod (1) is connected to the crane ship (
It is suspended from a mound (M) on the seabed, supported by a wire 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 hollow part of the rod (1) repeatedly strikes the lower striking plate (5) along its leader rail (4). The mound (M) or soft ground is compacted or finished by applying impact or vibration via the rod (1). Another embodiment of the present invention shown in FIG.
Steel rod (1) with a consolidation part (2) provided in a)
