Abstract

PURPOSE:To perform a rubble leveling operation from shallow sea to deep sea by a method in which rubbles are supplied through a supply chute set on the upper central part of a hanging frame and an intermediate supply chute connected with the first connector to the upper receiving chute of a rubble leveler. CONSTITUTION:Rubbles 11 are charged into the upper end hopper of a supply chute 3 fixed with a horizontal part to the center of a hanging frame 2 by a tension-leg system without effect of waves on the frame 2. An intermediate supply chute 3' is set below the chute 3 in the frame 2, and a receiving chute 3'' to be fixed to a rubble leveler 1 is set below the chute 3' through a chain 4 loosely provided. Operations involving feeding, installing, etc., can be easily performed till the operating region without effects of external forces, e.g., wind and waves.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floating type rubble supply device on the sea surface that is applied to a seabed rubble leveling device.

Conventional technology] A conventional rubble supply device has a leveling device installed at the bottom of a frame structure forming a formwork, and the leveling device above the leveling device is intended for use in shallow waters.
The rubble transported by means of conveyance such as a belt conveyor is supplied to a rubble supply device that protrudes above the sea, and then leveled by a leveling device.

It was leveling the ocean floor.

Problems to be Solved by the Invention] However, conventional rubble supply devices are for use in shallow waters;
When this was applied to the deep sea, it had the following drawbacks.

As structures become larger due to external forces such as wind and waves in the operating area, a great deal of time and expense is required for transportation to the operating area and installation. ■The manufacturing cost of the above structure is relatively high.

The present invention is intended to solve the above-mentioned drawbacks, and an object of the present invention is to provide a full-range, split-type rubble supply device for use in shallow to deep sea.

[Means for solving problems]

For this reason, the above-the-sea floating type rubble supply device of the present invention is a rubble leveling device for leveling rubble thrown into the seabed from the sea, and a hanging frame disposed above the rubble leveling device to lift the rubble leveling device. and a buoyancy tank constituting a vertical member of the hanging frame, the lower part of the buoyancy tank, and the upper part of the hanging frame.

A rubble supply chute supported by the central part of the hanging frame and disposed above the sea surface, a first connecting member connecting the lower end face of the buoyancy tank and the upper frame of the rubble leveling device, and the rubble supply chute a. It is characterized by comprising an intermediate supply chute connected to the lower side and above the receiving hopper for the rubble leveling device via a second connecting member.

[Effect]

With the above configuration, the rubble transported by the marine transportation means is transported through the supply chute disposed at the center of the hanging frame and further through the intermediate supply chute connected by the first connecting member.
It reaches the seabed through a receiving chute on a rubble leveling device connected by a second connecting member and installed at the bottom.

The front view, Figures 2 and 3 of this device are shown in Figure 1.
A line and ■-■ line arrow view are shown.

From Figures 1 to 3, the receiving hopper (13) on the seabed (13)
3"), the four corners of the rubble leveling device (1), which is a moving means, and the lower end of the buoyancy tank (6), which forms part or all of the vertical member of the floating frame (2), are connected by wire (connected by force). has been done.

By adjusting the amount of ballast in this buoyancy tank (6), the tension applied to the wire (force) can be controlled to an appropriate tension.

Due to this tension leg system, the hanging frame (2) is not affected by waves, and the supply chute (3), which is fixed in the center of the hanging frame (2) via a horizontal member, is fed with rubble from the hopper by a belt conveyor. It can be easily inserted.

A water supply pipe (8) for preventing rubble from clogging is provided diagonally upward in the circumferential direction of the upper part of the supply chute, and its lower part is fixed by a horizontal member from the lower part of the buoyancy tank (6).

Further, an intermediate supply chute (3') is disposed below the supply chute (3) within the hanging frame (2). A hopper is installed in the upper part of this intermediate supply shoe (3'), a drain port (a) is bored in the lower part, and the hanging frame meat supply chute (3) is connected from the upper circumference of the hopper through the chain (5). The receiving chute (3') is connected to the lower circumference and is able to follow the relative movement between the chutes, and is fixed to the rubble leveling device (1) below the intermediate supply chute (3').
)'fI: Disposed via a loosely provided chain (4) to prevent influence due to movement of the leveling device (1).

The hanging frame (2) has enough strength to lift the rubble leveling device (1), and hanging fittings (14) are fully installed at its four corners. There may be a plurality of intermediate supply chutes (3') to match the depth.

〔Effect of the invention〕

As described above, by providing the floating rubble supply device on the sea surface of the present invention, the manufacturing cost of the device can be reduced by 90% for leveling rubble on the seabed at depths from shallow sea to deep sea. effective.
