Abstract

The invention discloses a highway roadbed filling method based on construction waste. The highway roadbed filling method comprises the steps of pre-processing on a construction site, survey and setting out, basal layer treatment, pre-treatment of the construction waste, water insulation treatment of surrounding soil, laying and leveling of the construction waste, crushing of the construction wasteand quality inspection. The highway roadbed filling method based on the construction waste realizes high-quality filling of highway roadbed by utilizing the construction waste, largely solves the problem of excess construction waste, provides a reliable choice for materials and methods of roadbed filling, and achieves the concept of sustainable development by saving resources and protecting the environment to a certain extent.

Description

technical field [0001] The invention relates to the field of expressway subgrade construction of civil engineering, in particular to a filling method for expressway subgrade based on construction waste. Background technique [0002] In recent years, with the acceleration of my country's economic development and urbanization process, the total amount of construction waste such as concrete blocks, waste bricks and muck generated in the construction, maintenance and demolition of urban infrastructure is increasing day by day. According to relevant information: at present, the amount of construction waste in my country has accounted for 30-40% of the total amount of urban waste, and the total amount of construction waste piled up in my country has reached 7 billion tons, and the annual new generation of construction waste exceeds 400 million tons. Comprehensive processing utilization is less than 5%. There are more than 600 cities in the country, and more than 400 cities are fac...
