DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for reclaiming earth and sand, and more particularly to a method and apparatus for reclaiming earth and sand using a ruler barge navigating an earthmoving ship.

[0002]

2. Description of the Related Art In a conventional method for reclaiming earth and sand in a landfill using an earth moving ship, the earth moving ship is navigated to a sediment loading position by a push boat, and a safety depth (normally 4 to 4 water depths) is obtained by the earth moving ship.
About 5m), and then the bottom of the earth transport vessel may come into contact with the seabed, which makes it impossible for the earth transport vessel to enter the area. ing.

[0003] In order to reclaim land efficiently, earth and sand are sequentially injected by a soil carrier as flat as possible to a safe depth.
Immediately after the earth and sand loading of the earth transport vessel is completed, the earth and sand is scattered and landfilled with a reclaimer vessel.

[0004]

However, the above-mentioned conventional method of landfill using a soil carrier has the following problems.

A. Positioning of earth transport vessels

[0006] Since the ship is navigated to the earth and sand loading position by the pushboat, it is difficult to accurately maneuver the earth transportation ship to the earth and sand loading position.

B. Injecting earth and sand into the corner

[0008] Since the earth transport vessel is made to sail to the earth and sand input position by the pushboat, it is difficult to input the earth and sand to a location close to the revetment.

C. Even input

[0010] Since the earth and sand cannot be put into the correct position, it is difficult to bury the sand uniformly at the target depth.

D. Economics

Generally, a plurality of earth transport vessels are used for landfill.
Since a GPS receiver or the like is mounted on each of these soil carriers and a radio call is given from the land to guide the position of the soil carriers by a pushboat, the equipment cost is high.

E. Input trace surveying device

An input plan can be prepared by quickly preparing a water depth map after the input of earth and sand, but for that purpose, it is necessary to move an earth transport ship that hinders surveying.

F. Precise bathymetry

Since the measurement of human power is performed in red, the interval between the measurement points (mesh) is rough, and it is difficult to measure the soil volume with high accuracy to find the lowest value.

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

[0018]

SUMMARY OF THE INVENTION An earth and sand reclamation device according to the present invention is used to measure the topography of a barge to which a soil carrier for moving a soil carrier is attached and a sediment loading area provided on the barge.

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

In the present invention, as shown in FIG. 1 and FIG. 2, a ruler barge 2 to which an earth transport vessel 1 berths is used, and the position and direction information of the ruler barge are stored in the ruler barge 2. An acoustic sounding device 5 for detecting the depth of the seabed having two GPS receivers 3 to be detected, a telemeter 4, and, for example, ten transducers 5a.
, A computer 6 and a printer 7.

8 is a shore, 9 is a GPS fixed to the shore 8
Receivers 10 are telemeters for transmitting correction information from the GPS receiver 9 to the telemeter 4.

According to the present invention, after the earthing ship 1 is brought into contact with the ruler barge 2 by a pushboat, the soil carrier 1 and the ruler barge 2
The earth and sand loading position of the earth transport vessel 1 is input to the computer 6 in which the dimensional information is registered, and the earth transport is performed by the ruler boat 2 based on the position and orientation of the ruler boat 2 obtained by the GPS receiver 3 and the telemeter 4. The ship 1 is guided to the earth and sand input position.

The guidance status is displayed on the display 6a of the computer 6, and the input position is stored in the computer 6 as data to be reflected in the subsequent earth and sand input plan.

After the earth transport ship 1 is guided to the earth and sand input destination, earth and sand are injected on the spot, and after the earth and sand input is completed, the earth transport ship 1 is quickly moved.

At this time, the ruler barge 2 is operated by the winch operation.
Is moved so as to cross over the earth and sand charging completion range, and the depth of the range is measured using the sound sounder 5 of the ruler barge 2.

The computer 6 automatically draws a water depth map and an iso depth map from water depth data obtained from an acoustic sounding device, calculates soil volume and the like, and creates a sectional view with a predetermined mesh. Calculate the difference between the two, determine the amount of soil and soil, create a form, display the sounding value, the amount of soil, etc. on a display, etc., and print the input position actual map, soil volume calculation form, water depth map, iso depth map with a printer. 7 and so on.
