Foundation treatment method for living garbage deeply buried below roadbed

Abstract

The invention discloses a foundation treatment method for living garbage deeply buried below a roadbed. The method comprises the following steps: confirming a burying depth of a living garbage soil layer; confirming burying depths of various municipal pipelines under a road; confirming a minimum excavation depth of a deeply buried living garbage soil layer; if the burying depth of the living garbage soil layer is smaller than maximum burying depths of the municipal pipelines, completely eliminating off the living garbage soil layer; if the burying depth of the living garbage soil layer is greater than the maximum burying depths of the municipal pipelines, partially digging off the living garbage soil layer, flattening a field, constructing and prefabricating pipe posts, constructing post caps at the upper parts of the pipe posts, laying a lime soil pad layer, compacting and nursing the lime soil pad layer to strength, and refilling with plain soil in layers to elevation height of the roadbed; carrying out reverse pipe groove excavation, burying various municipal pipelines, and refilling pipe grooves; and grinding and compacting the roadbed till city road design standards, and carrying out surface layer construction after verification acceptance. By constructing prefabricated pipe posts, the foundation bearing capacity of the roadbed can meet design requirements.

Description

technical field [0001] The invention relates to the field of foundation treatment related to miscellaneous filled soil foundations under road beds, and more specifically relates to a foundation treatment method for deeply buried domestic garbage under road beds. Background technique [0002] With the rapid advancement of urbanization in my country, the amount of domestic waste generated in large and medium-sized cities in China is also increasing year by year. In the past few years, due to insufficient capital investment and difficult supervision and other reasons, a large number of informal landfills have been generated around big cities. According to relevant literature statistics, there are more than a thousand informal landfills in Beijing alone. The domestic garbage buried in the ground has complex components, and the pollution to the environment and the harm to people's health are becoming more and more serious. The main hazards are: 1. Pollution of water bodies: A l...

AI Technical Summary

Problems solved by technology

First of all, the cost of excavation and support will be high, especially for long and narrow structures such as urban roads, the cost of support will be higher

Secondly, in the process of excavating the foundation pit, the groundwater and the stress conditions of the surrounding buildings have been changed, which poses a greater safety hazard to the surrounding buildings and facilities

Third, when all domestic waste is excavated, the construction period for excavation and support will be longer, which cannot meet the needs of rapid urban development
