Road drainage pipeline engineering is one of the important contents of urban infrastructure construction

which is conducive to the construction of sponge city. Road drainage pipeline is of great significance to the development of the city

which can promote the discharge of urban sewage and improve the quality of people's living environment. At present

with the development of social economy

people put forward many requirements for the construction technology of road drainage pipeline engineering. During the construction

if there is a problem in the drainage pipeline due to inadequate technology

it may cause certain negative effects

which is not conducive to promoting the economic development of the construction unit. Therefore

the construction unit should attach great importance to the technical requirements of road drainage pipeline construction

so as to better improve the efficiency and quality of construction. This paper will briefly introduce Sponge City

and on this basis

explore the key points of road drainage pipeline construction in the construction of Sponge City.
