Surface drainage structures for civil engineering

Abstract

The invention provides a surface drainage structure for civil construction engineering. The surface drainage structure comprises a jacket, a grid plate, a screen drum, a mesh guard and a water seal structure, an upper end port of the jacket is matched with the grid plate, a lower end port of the jacket is matched with the water seal structure, the screen drum and the mesh guard are arranged in the jacket, the mesh guard is arranged below the screen drum, the mesh guard is provided with an enclosed cylindrical body, the middle of the side wall of the cylindrical body is recessed inwards, a circular hole is formed in the top of the mesh guard, the upper portion of the screen drum is supported on the inner wall below the upper end port of the jacket, the lower portion of the screen drum penetrates the circular hole in the mesh guard and extends into the mesh guard, and the wall surface of the screen drum outside the mesh guard are provided with screen holes. By the aid of the structure design, the surface drainage structure still can rapidly and smoothly drain after being used for a long time, frequency cleaning sediments in an end port structure is remarkably reduced, and convenience in use is provided.

Description

technical field [0001] The invention relates to the field of civil construction, in particular to the structural design of the inlet end part of the ground drainage system that can be used in civil construction engineering. Background technique [0002] The ground drainage system in civil engineering construction is an important part of the civil engineering field, and the structural design of the inlet end of the drainage system is particularly important to ensure the convenience and reliability of drainage at the root. Whether it is a toilet, kitchen, or public toilet in a residential building, the sewage inlet structure designed on the ground plays a vital role in ensuring that the indoor water is discharged quickly and smoothly, and that the pipes of the drainage system are not easily blocked. effect. [0003] As an essential part of all buildings, the indoor drainage system of civil buildings requires not only effective drainage and convenient use, but also the functio...

AI Technical Summary

Problems solved by technology

The front-end structure of the indoor ground drainage system is an important part of the building drainage system. At present, its design is constantly being optimized and improved. Due to the limitations of the product design structure, the convenience of use is still not ideal. During the use, it is necessary to frequently clean the deposited hair, impurities and tiny debris, otherwise it will lead to poor drainage or even blockage, and the deposited impurities and tiny debris The impact of debris on drainage smoothness and clogging is the main factor

Moreover, because the deposited impurities and tiny debris are finally deposited on the filter structure installed inside, the cleaning work is particularly inconvenient compared to the cleaning of hair.
