Municipal engineering road paving structure and construction method

Abstract

The invention relates to a municipal engineering road laying structure and a construction method, and belongs to the field of municipal engineering construction. The municipal engineering road laying structure comprises a base layer, a gravel layer and a surface layer which are sequentially laid from bottom to top, mounting frames are fixedly arranged in the base layer, and the upper plane of each mounting frame is flush with the upper plane of the base layer; a flow guide groove is formed in the upper plane of the mounting frame in the width direction of the base layer, a geogrid plate is fixedly arranged on the mounting frame and located over an upper opening of the flow guide groove, a drainage pipe is laid on one side of the base layer in the length direction of the road, a water outlet hole is formed in the bottom wall of one end of the flow guide groove and communicated with the drainage pipe, and the multiple mounting frames are arranged in parallel at intervals in the length direction of the base layer. In the process that underground water under the road flows from the cushion layer to the base layer, rainwater permeates into the flow guide grooves from the geogrid plates on the mounting frame, then flows towards the water outlet holes in the flow guide grooves and finally flows into the drainage pipe on the road side from the water outlet holes to be drained away, and the effect of improving the stability of the roadbed of the road is achieved.

Description

technical field [0001] The application relates to the field of municipal engineering construction, in particular to a municipal engineering road paving structure and construction method. Background technique [0002] Municipal engineering refers to the construction of municipal facilities. Municipal facilities refer to various buildings, structures, structures, etc. that are set up within the planning and construction scope of urban areas and towns (townships) based on government responsibilities and obligations to provide residents with paid or free public products and services. equipment etc. The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering, such as common urban roads, bridges, subways, and various pipelines closely related to life: rainwater, sewage, water supply, reclaimed water, electricity (parts outside the red line ), telecommunications, heating, gas, etc., as well as the construction of squares...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: rainwater often seeps into the base layer, and under the erosion and corrosion of rainwater, it is easy to cause the base soil layer under the road to be hollow and loose, making the road easy to crack, settle, and stable.
