Catch basin attachment

Abstract

The object of the present invention is to provide a drainage basin attachment which can prevent breeding of mosquitoes in a puddle inside the drainage basin and also can shield scattering of an odor from the inside. The attachment includes a supporting member retained to the upper end of the basin body and an inner gate supported by the supporting member beneath the basin lid to close the top opening of the basin body. The inner gate forms an inner basin for temporarily storing the rainwater passing through the basin lid. The inner gate is normally closed and is opened by an action of force acting on the inner gate by the rainwater accumulated in the inner basin to an extent above a predetermined level, thereby dropping the rainwater from the inner basin into the basin body.

Description

technical field [0001] The present invention relates to a drainage well attachment for drainage wells provided in side ditches of roads, foundations of homes and the like. More specifically, it relates to a drainage well attachment that prevents mosquitoes from forming in puddles inside the drainage well and blocks odors from dispersing from the inside. Background technique [0002] In the past, waste water was sent from the drainage hole formed on the well cover to the internal drainage well on the way of the drainage channel. Since the drainage channel was connected to the well body at a slightly above the bottom of the well, the bottom , will inevitably form puddles. Since a puddle is formed at the bottom of such a drainage well, mosquitoes are easy to invade from the drainage hole of the well cover, lay eggs in the puddle, give birth to larvae, and then form mosquitoes and fly to the outside from the drainage hole. In this way, drainage wells in roads, factories, and h...
