Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings of the description.
[0033] A municipal road drainage system comprises a municipal rainwater pipeline collection system, a green land purification infiltration system and a seepage drainage pipeline system. Overall, it is a road drainage design based on the combined model of "LID (Low Impact Development) + GSI (Green Infrastructure) + traditional technology".
[0034] like figure 2 , 3 As shown, the municipal rainwater pipeline collection system is a traditional drainage facility, which includes laying traditional traditional municipal rainwater pipelines 3, rainwater inspection wells and traditional flat grate rainwater outlets 4 under both sides of the motorway. The buried depth of the traditional municipal rainwater pipelines 3 is controlled at Below 2.5m, the overall elevation is lower than the laying elevation of the seepage and drainage piping system. The purpos...
