Abstract

PURPOSE:To provide firmly compacted rubble-mound, by a method wherein a travelling truck is laterally movably installed on a working ship, a guide leader and a damper device are located to the travelling truck, and rubble- mound is compacted through the working of the damper device. CONSTITUTION:A guide leader 20 is stood vertically to a working ship 1, and with a vibrator 41 started, the vibration is transmitted to a damper plate 43 through a casing pipe 42 to compact rubble-mound C1 on a sea bottom surface. Simultaneously, a pressurizing work is carried out throughout a specified width through movement, in the direction of the width of the working ship 1, of a travelling truck 10. Thereafter, after an anchor is lifted up to move the working ship 1 by a given distance, a compacting work is effected in a similar manner described above. In which case, the unwinding length of a wire 27 is regulated depending upon a water depth to hold the damper plate 43 in a proper position. This enables construction of underwater mound so firmly compacted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a compaction device for constructing a rubble layer, that is, a crushed stone foundation, on the seabed or the water bottom (hereinafter simply referred to as the water bottom).

[Prior Art] When constructing a foundation structure on the water bottom, for example, as shown in FIG.
! Ruble layers C1, Cz, C3 such as gravel and crushed stones are on the bottom B.
are sequentially formed to a predetermined thickness, and horizontal 3i! The proboscis D is grooved and a rubble FEE is formed.

In this way, the top surface of the rubble layer must be leveled to make it substantially flat. This requires a 12-person process for removing rubble and a screed process for leveling.

The present applicant has disclosed a screeding device necessary for the above-mentioned screeding process in Japanese Patent Application No. 58-1 2344, particularly 1982-1.
It was proposed by No. 53071. The underwater screeding device that we have devised has high work efficiency without requiring divers, etc.
Although it is effective in itself, it causes some unevenness on the finished surface and is not always satisfactory for leveling the surface.

The reason for this is presumed to be that the above-mentioned device does not substantially pressurize the surface of the rubble layer during the leveling work.

Therefore, the applicant of the present invention proposed an apparatus for leveling the material while applying pressure in Japanese Patent Application No. 58-21327. This device consists of a work boat that can be moored to a predetermined position with an anchor, a rubble hopper installed on the work boat, a belt conveyor that sends rubble from the rubble hopper, a secondary hopper that receives rubble from the belt conveyor, and a secondary hopper that receives rubble from the belt conveyor. A rubble vibrator connected to a hopper, a trolley that can be moved on a work boat, a hydraulic jack installed on the trolley, a pole that can be easily made using the hydraulic jack, a fixed frame attached to the pole, and a fixed frame. The electric motor installed in It consists of a weight placed on the

Therefore, a constant load is applied to the surface of the rubble layer through the bottom plate of the leveler, and the surface of the rubble layer can be leveled substantially horizontally by the reciprocating rotational movement of the leveler.

In this way, the method proposed in Japanese Patent Application No. 58-21327 applies a constant load while leveling the floor, so it is possible to level the floor substantially horizontally, but the applied load is low. It is not necessarily suitable for compacting rubble with straw at the maximum height, and is not suitable for forming strong underwater mounds.

[Object of the Invention] The present invention was completed through the development process as described above, and its main purpose is to provide a compaction device capable of forming a strong underwater mound. Moreover, it can be applied to the bottom of a large water body, and can be stored when being transported or moved. Another objective is to provide compaction equipment.

[Structure, operation, and effect of the invention] The compaction device according to the present invention includes a transverse truck movable on a work boat that can be moored at a predetermined position with an anchor, and the transverse truck has a vertical position and a horizontal position. It consists of a guide leader device that is pin-coupled so that the guide leader device can move, and a damper device that is provided on the guide leader device so as to be movable in the axial direction. It consists of a casing pipe that is connected to the casing pipe and is movably guided in the axial direction by the keeper of the guide leader device, and a damper plate that is provided at the tip of the pipe and directly pressurizes the rubble.

Since the present invention is configured as described above, during work, the work boat is towed to the construction site and moored at a predetermined position at 7 tons/J. Of course, while the J3 is being towed, the guide leader device is stored horizontally on the traversing truck. After the mooring work is completed, use a hoisting winch or the like to bring the guide leader device to a vertical position where it can be tightened.

When the guide reader device becomes H) ii:t, this is ↓
The old tamper device is also vertical, so use a winch or the like to lower it until the damper plate touches the rubble layer. □ Depending on the depth, it is also possible to add additional piping, or it can be adjusted by adjusting the length of the winch wire.

When the vibrator is started, the rubble is leveled under pressure by the damper plate. At the same time, the traversing trolley is run. As a result, the surface of the rubble is spread over a certain length in the width direction of the work boat under pressure. Next, raise the anchor, move the workboat, and repeat the above operations. The process is then repeated to spread the material over a certain area under pressure.

As described above, according to the present invention, the rubble is pressurized and compacted by the vibrator, so that a strong underwater mound is formed by 1q. Further, the guide leader device, and therefore the damper device provided thereon so as to be freely movable in the axial direction, is pin-coupled to the traversing truck, so that it can be stored horizontally during movement, such as when towing a work boat.

An embodiment of the present invention will be described below with reference to the accompanying drawings.
It is clear that the invention is not limited to the illustrated embodiment. For example, the guide leader device can also be raised and lowered by means of a piston-silling unit. Further, the traversing truck can be moved IJJ not only in the width direction of the work boat but also in the longitudinal direction. The casing pipe can be freely added to suit the construction depth, and the work boat can also be equipped with a rubble hopper, a bell mill conveyor, etc. It is also clear that various other variations are possible.
