Construction method of municipal administration road subgrade

Abstract

The invention discloses a construction method of a municipal administration road subgrade, and relates to the technical field of municipal road construction. The construction method comprises the following steps that (1), a foundation is handled, specifically, the protruding part of the foundation surface layer is removed, the sunken part of the foundation surface layer is filled and leveled up with soil, a road roller is used for repeated rolling from both sides to the middle, and the sunken part of the foundation is continuously filled with the soil until the foundation reaches the requireddegree of consolidation and intensity; (2), a bottom layer soil base is filled; (3), a function soil base is filled, specifically, the upper surface of the bottom layer soil base is sequentially filled with a saline-alkaline soil layer, an upper layer soli layer and a gravel layer, and the saline-alkaline soil layer, the upper layer soli layer and the gravel layer are compacted; (4), a rod surfaceis constructed; and (5), a drainage ditch is laid. According to the construction method of the municipal administration road subgrade, drainage performance of a road is increased, an anti-deformationdevice is arranged in the bottom layer soil base in the width direction of the rod surface, the situation of downward moving of the road surface due to the fact that the bottom layer soil base movestowards the two sides can be prevented, and meanwhile, damage to the road by living things can be effectively prevented.

Description

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