High-fill embankment filling construction process

Abstract

The invention provides a high-fill embankment filling construction process, and relates to the technical field of building construction processes. The high-fill embankment filling construction processspecifically comprises the following steps that S1, performing base treatment, specifically, treating a pavement foundation to be constructed; S2, performing layered filling, specifically, filling the embankment of the construction section in a layered mode, and performing filling of the next layer after filling of each layer is completed and compacted; S3, performing impact rolling; S4, arranging a temporary drainage system; S5, performing inspection and identification; S6, performing layer finishing; and S7, tampering the slope. According to the high-fill embankment filling construction process provided by the invention, the high-fill embankment can be filled in areas with poor soil and stone filler properties, much rainfall and poor roadbed stability through the construction process, and meanwhile, the situation of sedimentation after construction is completed can be avoided.

Description

technical field [0001] The invention relates to the field of building construction technology, in particular to a high-fill embankment filling construction technology. Background technique [0002] According to the definition of "Code for Design of Highway Subgrade", when the height of the fill slope is greater than 20m, it is called a high fill embankment. However, in some areas, the nature of the earth and rock filling is poor, the rainfall is heavy, and the stability of the roadbed is poor. At this time, the height of the fill slope can be defined as greater than 12m. When it is called high fill embankment. [0003] For the foundation in this area, the previous high-fill embankment construction method is difficult to achieve good construction results, and it is very easy to subside after the embankment is filled, and the quality is difficult to guarantee. Therefore, it is necessary to fill the high-fill embankment Improvements in construction techniques. Contents of th...
