Abstract

PROBLEM TO BE SOLVED: To increase the transshipment effect, by directly dropping loaded soil on a truck to a sand barge just under the truck through a chute, in the transshipment facilities for land reclamation soil of the sea from land transportation trucks to sand barges. SOLUTION: Barges 3 are contained in the space under the ferry port 1 of a pier projected from the land to the sea. A soilhaulage car like a dumptruck drops the loaded soil to a sand barge 3 right under the truck through a chute 7 installed in a ferry port 1, through an approach ramp 5 and returns to the land through an exit way 6. Car stops are provided at the opening edge of the chute. Guide posts 10 are erected at the approach entrance for the barges 3 and fenders are provided at the side thereof. Accordingly, belt conveyors, chutes, etc. for loading soil into barges are not required and haulage trucks can smoothly transfer and barges can smoothly come in and out. Simultaneous loading from a plurality of trucks becomes possible by providing a plurality of chutes 7 and hence the working efficiency is improved.

FIG. 1 is a plan view showing an embodiment of a jetty of the present invention, and FIG. 2 is a vertical sectional side view of the same. In the figure, reference numeral 1 is a main portion of the jetty projecting from land to sea at a distance of about 40 m from land. A crossing is shown, which is, for example, a rectangle with a width of 25 m and a length of 80 m, which is supported by a pillar 2 standing from the sea floor, and a space 4 into which a 4000 m ³ class earth carrier 3 can enter is formed below.

And the exit path 6 with a width of 8 m on the other side,
A plurality of inlets 7 for earth and sand or the like were opened at appropriate intervals along the length of the crossover portion 1. As a result, the flow line of the carry-in vehicle 8 is formed from the approach path 6 communicating with the land to the exit path 6 communicating with the land via the inlet 7 of the crossover 1. In the figure, 9 indicates a car stop provided at the opening edge of the inlet 7.

ある。At the entrance of the earthmoving ship 3 to the space 4 below the crossover 1, for example, an introduction pillar 10 is provided as an introduction portion for guiding the approach direction, and the side portion of the pillar 2 facing the space 4 is provided. A fender 11 made of a material such as wood is provided on. This introduction pillar 10 has a structure in which a pillar is placed in the extension of the approach path 5 which is a pier and connected in the horizontal direction, and a fender is attached. This is to make it easy to guide it under the mouth 7.

る。As described above, in order to transfer the earth and sand from the loading vehicle 8 such as a dump truck to the earth-moving ship 3, the earth-moving ship 3 is arranged in the space 4 below the crossing section 1. In this case, since the introduction pillar 10 is provided at the entrance to the lower part of the crossover 1, the earthmoving ship 3 can be smoothly arranged in the lengthwise direction of the crossover 1 by moving along the introduction pillar 10. Further, since the fender 11 is also attached to the column 2, the earthmoving ship 3 can be moved smoothly. In this state, the earthmoving ship 3 is located immediately below the loading port 7.

接落下する。On the other hand, the carrying-in vehicle 8 loaded with soil or the like enters the crossing section 1 through the approach path 5, and the rear part of the vehicle is directed toward the loading slot 7 and is retreated to a position where the rear wheels hit the car stop 9. If the vessel of the carrying-in vehicle 8 is set up, the loaded earth and sand will slide down into the loading port 7 from here, and will fall directly on the earth carrier 3 directly below.

することも可能である。Since a plurality of loading ports 7 are formed, a plurality of loading vehicles 8 can load the loading ports 7 in a short time if the loading ports 7 are simultaneously used. If the earthmoving ship 3 is moved several meters in the lengthwise direction of the crossing section 1, it can be evenly loaded on each section on the ship. In this case, since the crossing section 1 is separated from the land by about 40 m, it is possible to move the earthmoving ship 3 in the land direction.

スムーズに移動できる。The loading vehicle 8 which has finished the loading of the earth and sand into the soil carrier 3 moves forward and moves from the exit route 6 to the land. In this way, the flow line of the carry-in vehicle 8 is determined in one direction from the approach path 5 to the exit path 6 through the entry port 7, so that a plurality of carry-in vehicles 8 enter the crossover section 1. But you can move smoothly.

る。As described above, when the pier of the present invention is used for loading and unloading earth and sand from a vehicle for loading and unloading earth and sand to a sand carrier, the pier can be directly transferred from the vehicle to the earth carrier. Is unnecessary, and it is possible to prevent the work efficiency of transshipment from decreasing due to the adhesion of earth and sand to the device.
