BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for collecting suspended waste when dumping waste at a waste disposal site provided in a predetermined sea area, and an apparatus for implementing the method for collecting suspended waste. It is about.

[0002]

2. Description of the Related Art Conventionally, waste is disposed of by dumping it into a waste disposal site that is buried in the ground or a waste disposal site that is constructed by setting a partition wall in a predetermined sea area. Of these, a landfill using the underground burial method has a large concave portion formed in the ground so that a large amount of waste can be dumped, and the waste is dumped in this concave portion and landfilled. However, the waste disposal site using the underground burial method has a problem that it is difficult to secure a large-capacity development site due to land acquisition problems and geographical restrictions.

On the other hand, the method of dumping a waste at a waste disposal site constructed by setting a partition wall in a predetermined sea area can be widely used on the sea. No problem.

[0004]

By the way, the waste dumped at the waste disposal site is different from general household waste,
When targeting illegally dumped waste, disaster / fire trace waste, road cleaning waste, etc., combustible materials such as paper waste, fiber waste, wood waste, etc., incombustible materials such as waste plastic and construction waste materials, and large houses and waste products Things are the subject.

[0005] When such waste is discarded at a waste disposal site constructed in the sea area, it is separated into suspended waste and settled waste. Of these, the latter settled in the sea and settled in the sea and contributed to landfills, whereas the former suspended wastes such as paper and wood chips contributed to landfills in the waste disposal sites. And float in the sea area.

[0006] This suspended waste becomes a hindrance to the next waste disposal, so it is necessary to collect it. However, since the floating area and the depth thereof are wide, it is efficient with ordinary manual work. Cannot be collected. Therefore, it is conceivable to collect the suspended waste by using a heavy machine such as a crane equipped with a draining device.
It is necessary to collect suspended waste within a certain area.

The present invention has been made in view of the above-mentioned conventional problems, and has been developed in order to facilitate the collection of suspended waste among the waste dumped at a waste disposal site constructed in the sea area. It is an object of the present invention to provide a method for collecting suspended waste at a predetermined place and an apparatus for performing the method.

[0008]

In order to achieve the above object, the present invention provides a collection net in a closed water area provided in a predetermined sea area, and jets a water flow from the quay toward the collection net.
