The invention discloses a municipal engineering road paving structure which comprises a roadbed layer, a pipeline frame is arranged in the roadbed layer, inserting blocks are arranged on the two sidesof the upper end of the pipeline frame, a concrete prefabricated plate is arranged at the upper end of the roadbed layer, inserting grooves are formed in the two sides of the bottom end of the concrete prefabricated plate, and a main connecting block and an auxiliary connecting block are arranged on one face of the concrete prefabricated plate. A groove and a clamping block are arranged on the other face of the concrete precast slab, a main penetrating hole and an auxiliary penetrating hole are formed in the main connecting block and the auxiliary connecting block respectively, and an embedded bolt and a protruding block are arranged on the groove and the clamping block respectively. The asphalt layer on the surface of the concrete precast slab is scraped off, the nuts and the fixing bolts are detached, the hanging ropes are fixed to the hoisting blocks on the two sides of the bottom end of the concrete precast slab to hoist the concrete precast slab, the pipeline is maintained and replaced, the concrete precast slab is fixed to the pipeline frame again after maintenance is completed, and the asphalt layer is laid on the surface of the concrete precast slab again. The structure has the characteristic that the pipeline can be maintained and replaced without damaging the concrete precast slab.
Description
technical field [0001] The invention belongs to the technical field of municipal engineering, and in particular relates to a road paving structure for municipal engineering. Background technique [0002] Beams, subways, underground pipelines, tunnels, rivers, rail transit, sewage treatment, garbage disposal and other projects, and various pipelines closely related to life: rainwater, sewage, water supply, reclaimed water, electricity, telecommunications, heat, gas etc., as well as the construction of squares and urban greening, etc., all belong to the category of municipal engineering. [0003] Road engineering refers to the whole process of planning, design, construction, maintenance and management of roads and the engineering entities involved. Like any other category of civil engineering, road engineering has obvious technical, economic and management characteristics. In the construction process of existing municipal roads, municipal pipelines are usually pre-embedded i...
