Environment-friendly overflow rainwater port

Abstract

The invention discloses an environment-friendly overflow rainwater port which is installed in the opening position of a drainage vertical pipe. The environment-friendly overflow rainwater port comprises an overflow grate and a connecting pipe seat, wherein the overflow grate is of a cylindrical structure, the top of the overflow grate is provided with an overflow port, the side of the overflow grate is provided with an overflow groove, and the connecting pipe seat connects the drainage vertical pipe with the overflow grate. The environment-friendly overflow rainwater port is simple in structure and easy to construct, that is, a common operator can complete the construction operation. Meanwhile, the overflow grate and the connecting pipe seat are fixed through screws, a cover cannot be directly opened, the size is small, and even after the cover is opened, people cannot fall into a connecting pipe. The environment-friendly overflow rainwater port is small in appearance but large in design flow and high in water passing rate, the drainage safety is achieved, the environment-friendly overflow rainwater port can easily match with surrounding landscapes, and the overall landscape effectis improved. The environment-friendly overflow rainwater port also has the advantage of low manufacturing cost, the price of one set is reduced by at least 50% or above, and the cost consumption is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering, and in particular relates to an environmental protection overflow rainwater outlet. Background technique [0002] In municipal construction, traditional overflow wells mainly have two structures: one is a brick well with a cast iron overflow manhole cover, and the other is a finished well with a shaft and a cast iron or plastic overflow manhole cover. Although these two structures can achieve a large displacement, they have the following disadvantages: [0003] (1) The structure is complex and the construction is cumbersome, especially the brick wells have higher professional requirements for construction workers; [0004] (2) The overflow manhole cover can be opened directly, and there is a risk of people falling into the well; [0005] (3) The appearance is poorly coordinated with the surrounding landscape; [0006] (4) The cost is relatively high, and the average price of a se...
