Abstract

PROBLEM TO BE SOLVED: To eliminate such a disadvantage that a wide range of ground can not be levelled in a short time because the rolling compaction area of a leveling plate is small, in conventional mound leveling equipment of submarine ground. SOLUTION: One end of a slide rail is inclinably pivoted to a staging hung down from a construction craft and mounted on a mound, and a leveling rake or a compacting roller is slidably guided along the slide rail, in the present mound leveling equipment of submarine ground.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mound leveling device for a seabed, and more particularly to a mound leveling device for a seabed which can level a wide area at a time.

[0002]

2. Description of the Related Art In general, when a harbor structure or the like is constructed on soft ground, a method is adopted in which sand piles are previously formed on the seabed ground to strengthen the soft ground, and a mound is formed to disperse the load. .

In this case, the mound is leveled by the diver's manpower, and concrete blocks, weights, etc. are lifted by a crane ship and allowed to fall naturally and compacted. However, seawater resistance, buoyancy and water at the time of landing are fixed. The energy is greatly reduced by the cushion and the like, and furthermore, the displacement is caused and the sufficient effect cannot be obtained.

[0004] For this reason, a method of compacting and mounding a mound on the seabed by a sand pile building ship disclosed in Japanese Patent Application Laid-Open No. 3-166419 has been proposed.

[0005]

However, in the above-mentioned conventional leveling method, there is a drawback that a wide area cannot be leveled in a short time because the rolling area of the leveling plate is small.

The present invention has been made to eliminate the above disadvantages.

[0007]

According to the present invention, there is provided a mound leveling device for submarine ground, comprising: a stand suspended from a work boat and placed on the mound; and a slide having one end pivotally supported on the stand. It is characterized by comprising a rail, a leveling rake and / or a pressure roller slidably guided along the slide rail, and a moving means of the leveling rake and / or the pressure roller.

The present invention is characterized in that it has a control means for controlling the inclination of the slide rail.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2, 1 is a work boat, 2 is a mound on the sea floor, 3 is rubble, 4 is a slope of the mound 2, 6
Denotes a leveling device suspended vertically by a wire 5 from a crane (not shown) provided on the work boat 1,
In the present invention, a pedestal 7 on which the leveling device 6 is mounted on the mound 2, a leveling winch 8 provided on the pedestal 7,
A slide rail 9 having one end pivotally supported on the gantry 7, and a carriage 11 moved along the slide rail 9 by the leveling winch 8 and the leveling wire 10.
A leveling rake 15 fixed to the carriage 11 so as to be movable along, for example, the slope 4 of the mound 2, and / or a pressure roller 12 rotatably supported on the carriage 11, and a lift for raising and lowering the slide rail 9. It is composed of a winch 13 and a lifting wire 14. The smoothing rake 15 and the pressure roller 12 may be both attached to the carriage 11 so as to be retractable so that both can be used simultaneously or one of them can be arbitrarily selected at the time of use.

Since the undersea ground mound leveling device of the present invention has the above-described configuration, the inclination of the slide rail 9 is correctly matched with the mound 2 by the rail lifting winch 13 and the lifting wire 14, and the leveling winch 8 If the carriage 11 is moved along the slide rail 9 by the leveling wire 10, not only the upper surface of the mound 2 but also the rubble 3 on the slope 4 is leveled very easily by the rake 15 and / or the pressure roller 12. In addition, the area corresponding to the length of the slide rail 9 can be leveled at one time by one reciprocating movement of the carriage 11.

[0012]

As described above, according to the mound leveling device for submarine ground according to the present invention, a wide range can be leveled at a time without moving the hull 1, and a great advantage that the working time can be greatly reduced can be obtained. is there.
