Study on Optimization of New Type of Seepage Well Structure in Sponge City

摘要

The seepage well is an indispensable part of the construction of the sponge city. It has a good "elasticity" for the city to adapt to the environmental changes and respond to natural disasters. In the face of the current decline in the groundwater level and the water logging in the city, it is urgent to study the new type of seepage well under the complex geological conditions. In this paper, the advantages and disadvantages of the current seepage well structure are analyzed, and combined with the hydro-geological conditions in the area of Feng Xi new city of xi'an, three new types of seepage wells are put forward, such as reinforced concrete filter pool + mufti glass pipe combined structure seepage well, masonry filter pool + single glass pipe combined structure seepage well and prefabricated reinforced concrete structure seepage well. The advantage, disadvantage and applicability of the well are compared, and case analysis is provided, which provides a basis for the construction of seepage wells in sponge cities.
