The invention discloses a municipal engineering road paving structure, which comprises a road base, a pipe frame is installed in the road base, inserting blocks are installed on both sides of the upper end of the pipe frame, a concrete prefabricated slab is installed at the upper end of the road base, and the bottom of the concrete prefabricated slab There are slots on both sides, one side of the precast concrete slab is respectively equipped with a main connecting block and an auxiliary connecting block, the other side of the precast concrete slab is respectively provided with a groove and a clamping block, and the main connecting block and the auxiliary connecting block are respectively provided with a main perforation And the secondary perforation, the groove and the block are respectively equipped with embedded bolts and projections. Scrape off the asphalt layer on the surface of the precast concrete slab, remove the nuts and fixing bolts, fix the lanyard on the lifting blocks on both sides of the bottom of the precast concrete slab to lift it up, and maintain and replace the pipeline. The maintenance is complete After that, the concrete prefabricated slab is refixed on the pipe frame, and the asphalt layer can be laid on its surface again, which has the feature of maintaining and replacing the pipeline without destroying the concrete prefabricated 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...
