Claims

[Scope of claim for utility model registration] A generally rectangular trench pit buried under the edge of a road shoulder as part of rainwater treatment, and a sewerage system connected to an outflow hole drilled in the underground side wall of the trench pit. It is a trench pit equipped with a device for draining filtered fresh water into a connecting pipe, in which a solid rectangular well frame is normally loaded and joined to a pre-excavated pit, and the side wall of the well frame has no water flowing out. An opening for water is drilled and a sewer communication pipe is connected to the opening to form a buried trench with open upper and lower surfaces, and the lower part of the trench is used as a water reservoir. A cubic framework made of round rods made of stainless steel, etc., which is rust-resistant even if there is no dam, is formed in the water storage part, and a filter made of natural or chemical fiber is installed to cover the entire upper surface of the cubic framework. The filter layer is provided in such a way that it will not easily come off, and a tip tube of a large funnel that penetrates the filter layer is inserted into the water reservoir portion from approximately the center of the upper portion in a communicating manner, so that the expanded receptacle of the large funnel is inserted. The mouth shape is formed to almost match the inner dimensions of the rectangular frame, and a repellent net is installed inside to constitute a filtration device, and the trench is placed at a position slightly below the upper opening side of the trench. A trench basin equipped with a filtration device installed integrally with a large funnel and a large funnel communicating with the inside of a water storage part provided with a filter layer below.
