Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a barge for water surface reclamation work.

(Prior art) Conventionally, positioning of this type of work barge involves measuring the barge position discontinuously by manual operation using a transit, sextant, etc., mooring the barge by manual operation, and Measurements of the reclaimed surface were also performed manually using measuring rods, etc., and dump trucks were guided by human signals using flagpoles, etc.

(Problems that the invention aims to solve) Conventionally, the positioning of the work barge has been done manually, so it takes time to move it, the measurement accuracy is low, and the measurement of the reclaimed surface has also been done manually. Because of this, it took time to measure, and there were problems with measurement accuracy. Furthermore, the guidance of dump trucks is carried out manually without knowing the details of the landfill or the immediate situation, which results in a lot of time and economic loss, and it is difficult to maintain the accuracy of the landfill, such as the planned height and uniformity of the landfill surface. They were also inferior in points.

(Means for solving the problem) The present invention was proposed to solve the above problem. An automatic barge positioning device comprising an automatic barge position measuring device, and a control device that receives a measurement signal from the measuring device and controls the amount of anchor cable winding and payout of the anchor cable winding winch; An automatic water depth measuring device is movably mounted along the side of the barge, and a signal from the water depth measuring device to measure the shape of the water bottom or reclaimed area is used to indicate the dumpout position of the dump truck transferred onto the barge. a dump truck guiding device that guides the dump truck to the relevant position; and a bottom leveling device that is movably disposed along the side of the barge and whose height is adjusted in response to a measurement signal from the automatic water depth measuring device. This relates to a barge for land reclamation work, which is characterized by the following:

(Function) Since the present invention is constructed as described above,
The barge position measurement position signal from the barge position automatic measuring device is sent to the control device, and the control device adjusts the amount of winding and unwinding of the anchor cable winches arranged on the front, rear, left and right sides of the barge. To quickly and accurately move and moor a barge to a destination.

Next, the automatic water depth measuring device is moved along the side of the barge to automatically and accurately measure the shape of the reclaimed surface at the bottom of the barge, and sends a shape measurement signal of the reclaimed surface to the dump truck guiding device, which guides the dump truck. The dump truck is instructed to the dump out position where the landfill work can be carried out most efficiently, and the dump truck is guided to that position.

Next, the underwater leveling device is moved along the side of the barge to level the reclaimed surface, and at this time,
The height of the leveling device is raised or lowered by the measurement signal of the automatic water depth measuring device to uniformly level the uneven portions of the reclaimed surface.

(See Figures 3 and 4) By moving the pedestal 10 along the guide member 8, the water depth below the gunwale is measured,
Measure the shape of the bottom of the underwater part (B) or the reclaimed part (C).

The automatic water depth measuring device 9 displays the levels of the reclaimed surface and water bottom surface during and before and after the reclaimed water in a graphical and digital manner, and sends a signal to a dump truck guiding device to be described later.

The automatic water depth measuring device is comprised of an ultrasonic type, a weight type, a pressure type depth probe, and the like.

FIG. 5 shows a dump truck guiding device, which receives a measurement signal of the shape of the water bottom or reclaimed land from the automatic water depth measuring device and guides the dump truck 15 boarded on the barge 1 to the dump-out location. , is displayed on the dump truck destination information board 16 located near the rampway 7, and the dump truck 15 is displayed on the dump truck destination guide board 16 located near the rampway 7, and also by the lighting display section 18 of the dump truck guidance instruction lamp 17 arranged at each part of the barge 1. to ensure that guidance is provided.

In addition, a dump truck counting and weighing device 19 is installed near the rampway 7 on the barge 1.
is installed to display and record the total number and loading capacity of the dump trucks 15 transferred onto the barge 1, and to display and record the total number and loading capacity of the dump trucks 15 that are on board the barge 1 at the same time.
It also measures the number of dump trucks and controls boarding of dump trucks.

A guide member 20 is disposed on the side of the barge 1 in the longitudinal direction, and a traveling device 22 of an underwater leveling device 21 is movably mounted along the guide member 20. The device 21 includes a sliding rod 2 whose height is adjusted based on the measurement signal from the water bottom or the reclaimed area by the automatic water depth measuring device 9.
3, and a ground leveling mechanism 24 at the tip of the same rod 23.
is mounted.

(See FIGS. 6 and 7) FIGS. 8 and 9 show other embodiments of the underwater leveling device 21, in which a lifting support arm 26 is attached to a base machine 25 that freely runs on the barge 1. A sliding rod 23 is attached to the leveling device 21 supported through the ground leveling device 21.
