Embodiment Construction
[0043] Attached to the following Figure 1-5 This application will be described in further detail.
[0044] The embodiment of the present application discloses a road paving structure for municipal engineering. refer to figure 1 , the road paving structure includes a base layer 1, a cushion layer 11 and a surface layer 12 laid from bottom to top. In this embodiment, the base layer 1 adopts a cement-stabilized gravel layer, the cushion layer 11 adopts graded gravel, and the surface layer 12 adopts concrete or. In other embodiments, the base layer 1 can also use lime and fly ash stabilized soil, the cushion layer 11 can also use lime cinder soil, and the surface layer 12 can also use concrete.
[0045] refer to figure 2 , 3, 4. A mounting frame 2 is embedded in the base layer 1, and the mounting frame 2 is formed by pouring concrete. The installation racks 2 are installed along the width direction of the road, and the installation racks 2 are evenly spaced along the lengt...

Abstract
The present application relates to a municipal engineering road laying structure and construction method, belonging to the field of municipal engineering construction and construction. The upper plane is flush with the upper plane of the base layer, the upper plane of the mounting frame is provided with a diversion groove along the width direction of the base layer, and a geogrid plate is fixed on the installation frame, and the geogrid plate is located directly above the upper opening of the diversion groove. One side of the base layer is laid with a drainage pipe along the length of the road, a water outlet hole is provided on the bottom wall of one end of the diversion groove, and the water outlet hole is connected with the drainage pipe. When the groundwater under the road flows from the cushion to the base layer, the rainwater seeps into the diversion groove from the geogrid plate on the installation frame, and then flows into the water outlet hole in the diversion groove, and finally flows into the drainage pipe on the road side from the water outlet hole. Drainage, the present application has the effect of improving the stability of the road subgrade.
Description
