Problems solved by technology

[0003] However, at present, in the construction process of subgrade filling, the soil material is shaped, and then it is carried out through initial pressure-manual leveling-roller rolling. If the compaction degree meets the specifications, the next layer of filling will be carried out. The above process requires a lot of work. It needs to be rolled once, and it needs to be tested once to achieve the best effect. The roadbed laid by this method is time-consuming, manpower and material resources, and the degree of compaction can be further improved

Abstract

The invention provides a municipal roadbed construction method which comprises the steps that a construction site is cleaned, the surface layer of a foundation is loose soil, and if the thickness of the loose soil is lower than than or equal to 30 cm, the loose soil is ground to the compactness of 90% after sundries are removed; if the thickness of the loose soil is larger than 30 cm, the loose soil is compacted in a layered mode till the compaction degree is 90%; the cleaned construction site is subjected to soil material backfilling, and the accumulated thickness of the laid soil material ranges from 50 cm to 60 cm; the moisture content in the soil material is controlled to be 30-50%, a curing agent is added into the soil material, uniformly stirring and mixing are implemented, the uniformly mixed soil material is paved through a bulldozer, and the soil material is flattened; and the flattened soil material is rolled through a light path road roller so as to quickly cure the soil material added with the curing agent, and the laid multiple layers of soil materials are repeatedly rolled . The roadbed is thus paved. Due to use of the curing agent, the compaction degree and the bearing capacity of the roadbed can be improved to a certain extent.

Description

technical field [0001] The present disclosure relates to the technical field of roadbed construction, in particular to a municipal roadbed construction method. Background technique [0002] Municipal engineering refers to the construction of municipal facilities. In my country, municipal facilities refer to various buildings and structures that are set up within the planning and construction scope of urban areas, towns and villages, and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. And equipment, various public infrastructure constructions supporting urban life belong to the category of municipal engineering, common urban roads, bridges, subways, various pipelines closely related to life: rainwater, sewage, upper water, reclaimed water, and parts other than the red line of electricity , Telecommunications, heating, gas, and squares, urban greening construction, all belong to the category of municipal en...
