The present invention relates to a device for preventing pest and infection for a manhole, comprising: a container having an internal space, while having an injection hole on the top for inputting a liquid for preventing pest and infection, and an outlet on the bottom for emitting the same liquid; a fixating unit formed and elongated upwards from the top of the container, for forming a holding bump on the top which penetrates the drainage of the manhole and is held onto the top of the manhole; a pest-preventing hose connected to be funneled with the outlet of the container and to emit the liquid for preventing pest and infection supplied from the outlet toward the outside; and an amount adjuster formed on the pest-preventing hose to pressurize the outside of the pest-preventing hose in order to adjust the size of the internal passage of the pest-preventing hose. By periodically emitting the liquid for preventing pest and infection filled inside the container through the pest-preventing hose connected with the outlet of the container using the amount adjuster into the sewer, the reduction in the effect of the liquid for preventing pest and infection due to the flow of the sewer can be prevented in advance, thereby effectively blocking the spawning of pests and outbreak of infectious diseases, leading to an excellent disease control inside the sewer. Moreover, since the container can be easily hung to the drainage of the manhole by the fixating unit and provides a continuous disease control by periodically refilling the liquid for pest and infection control through the injection hole of the container thereafter, user convenience and excellent disease control effect can be expected. |
