Abstract

PURPOSE:To easily carry out dredging work by connecting a transport ship which is loaded with the soil, sand, etc. and goes down a river and a vacant transport ship, in detachable ways by a traction rope in loop form, in the dredging for the piled soil, sand, etc. on the bottom of a dam. CONSTITUTION:The soil, sand, etc. after dam dredging work are once loaded onto a dump car and conveyed to a loading yard on the downstream of a dam, and loaded onto a transport ship A. The transport ship A opens the wing C and coveys the soil, sand, etc. along the stream of a river to a soil dumping field on the downstream. A vacant transport ship B which goes upstream in the river is connected in detachable ways onto a traction rope 1 forming a loop along the river, and then the ship can return to the upstream easily, closing the wing C, since the draft is shallow. Thus, the need of a long road for damp car and the use of a long-distance transport truck is avoided, and the dredging work for the dam is facilitated.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to construction work for dredging sediment, etc. accumulated at the bottom of a dam, and requires a special cost to transport the dredged sediment, etc. to a sediment dumping site. The present invention relates to a method for transporting large amounts of earth and sand at low cost without using such a method.

(Conventional technology) Isn't there sediment, etc. in regular dams along with the water flow from upstream?
Over many years, a large amount of earth and sand accumulates on the bottom of the dam, eventually reaching the point where it impairs the normal functioning of the dam. Therefore, dredgers and other equipment are used to dredge the earth and sand from the bottom of the water, but conventionally, the dredged earth and sand are loaded onto trucks.

If you go to the soil dump! I threw it away after 11.

(Problems to be Solved by the Invention) - In the above conventional method, the first dumping site is located far away from the dam, and a truck road is constructed from the dam to the first dumping site, and a large dumping site is Because it has to be transported by truck etc.

Due to the huge cost involved, the dams were not dredged except for a few.

(Means and effects for solving the problems) This invention was made in view of the above points.

Earth and sand dredged by a dredger at a dam.

Once loaded onto a dump truck, it is transported to a loading site located immediately downstream of the dam, or transported to the loading site using conventional techniques such as slurry transportation, and then loaded.
The cargo is loaded onto the transport vessel according to the present invention at the shipping site. Transport ships operate by using river flows made up of running water released from dams, and include multiple transport ships (hereinafter referred to as A) loaded with earth and sand, as well as empty transport going back up the river. ship(
8 points (abbreviated below) form a loop along the river ()
Tied to the towing robe.

In addition, the transport ship is equipped with wings (hereinafter abbreviated as C) that can be opened and closed to receive the river flow.

When A goes down the stream, C is opened, and the weight of the earth and sand causes A to move further down the stream.
Since the stagnant waters of A are deep, A receives sufficient flow from the river and moves downstream.

At the soil dump downstream of the river, A was removed from the tow rope and 2
The earth and sand are thrown away at the soil dumping site, and the empty part B is formed and tied to a tow rope. Since the tow rope is looped along the river, B heads toward the 1-stream, but at this time, C of B is closed, and since B is empty, the water is shallow and there is little resistance from the flow. , since the downstream force of A is large, F3
can easily return to the 1-stream. When the 13 arrived at the upstream loading area, it was pulled out from the tow rope.
-1- Loaded with sand, etc. 71 and tied to a tow rope to become 8. In this way, the present invention -1- flows from the loading site to the downstream soil dumping site.

It transports earth and sand by transportation n1) that uses the flow of a river and does not require a motor.

(Example) Embodiments of the present invention will be described below based on the drawings.

In Figure 1, ■ indicates that sediment, etc. from the bottom of the water is being collected by a dredger, etc. The collected sediment, etc., is transported to the loading area O by a dump truck (not shown), and is placed in a hopper, etc. located at ■. Load onto a transport ship. Since the details of ①, ②, and 0 are not important to the present invention, only an outline is shown in FIG.

A is tied to the Mebuki row 11 on the downward side.

As you can see, since it is deeply submerged in the water, it receives a large downward force from the flowing water and moves down the stream.

A arrives at the soil dumping site shown in Figure 1 ■ and pulls the tow rope 1.
A was removed from the waterway by the method outlined in Figure 3 fat to fdl (Figure 3 fat to fdl).
), transportation (Fig. 3 fbl) Knock down L and A to empty the earth and sand (Fig. 3 tel), and transport the empty transport vessel to the waterway (Fig. 3 (d)). The details of FIG. 3 fat to fdl will be omitted since they are not important to the present invention.

The empty transport ship is tied to the tow rope B in Figure 1 (2), and is pulled upstream by the tow rope 1' on the upstream side. The details of this B are shown in Figure 2 fat.
As shown in Figure 2 (fcl, fd), the wing C is closed, and as can be seen by the mesh B' in Figure 2 (fdl), there is little submerged part, so there is less resistance to go upstream. It is small and can be easily pulled upstream by the tow rope 1'.

The tow ropes 1 and 1' are connected around pulleys designated 2 and 2' so that they move continuously along the waterway.

The wing C is supported on a hinge 3 shown in FIG. 2 fa).

3 has a structure in which the wing C can be opened and closed by 90 degrees, but the details are omitted.

The transport ship and the tow rope are hinges 4 and 4 attached to the front and rear of the transport ship as shown in Figure 2 fb) and (C).
', hook parts 6 and 6' branched from the tow ropes 1 and 1', and a connecting rope 5 that connects 4 and 6 and 4' and 6'.
and 5'. The connection between the transport vessel and the tow rope.

Since conventional techniques such as commonly used lifts can be applied, detailed explanation will be omitted.

Two tow ropes 1 and 1' are guided along the waterway by pairs of guide rollers 7 and 7'. The guides 11 - rough and 7' are rotatably pivotally connected to a guide roller shaft 8 provided on a support stand 9 built across the waterway.

(Effects of the Invention) Since the present invention is constructed as described above, the sediment, etc. accumulated at the bottom of the dam is dredged, and the sediment, etc., transported to the loading area provided downstream of the dam is drained from the water flow from the dam. The soil is automatically transported to the downstream dumping site by the transport ai) used, and the empty transport vessel is also automatically returned to the original loading site, eliminating the need for long roads for dump trucks as in the past. , there is no need for trunks for long-distance transportation, resulting in significant cost reductions, making dredging of dams, which was previously not often done due to high costs, easier, and the useful life of dams can be expected to be significantly extended. .
