The invention relates to the field of municipal pipeline construction, in particular to a construction method of municipal road pipelines. The construction method comprises the steps that S1, trenchesare excavated; S2, the bottoms of the trenches are leveled; S3, pipeline seats are placed; S4, pipeline units are hoisted; S5, cement mortar is coated on the outer walls of the joints of the adjacentpipeline units; S6, after concrete connecting pipes are solidified, the trenches are filled with gravels; S7, slurries are poured into the trenches until the slurry level is higher than the gravels;S8, the tops of the trenches are completely covered with waterproof materials, and then still standing is conducted for at least 3 d; S9, the trenches are backfilled with soil to the soil layer heighthigher than the original pavement; S10, the backfilled soil is compacted to form a road soil layer; S11, the height of the road soil layer is adjusted to meet the road design requirements; and S12, roads are paved. The construction method has the effects that the municipal road pipelines are not prone to bending and breaking due to local stress, the structure is stable, leakage is not prone occurring, the pavement is stably supported, and the quality of the municipal roads and the municipal road pipelines is good.
