Embodiment Construction

[0032] Various embodiments of the invention will be described in more detail below with reference to the accompanying drawings. In the various drawings, the same elements are denoted by the same or similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale.

[0033] refer to figure 1 with figure 2 , the application provides a construction method for rock-filled embankments, comprising:

[0034] Step 1, processing the ground bed 1, obtaining the bearing capacity data of the ground bed 1, and when the bearing capacity of the ground bed 1 cannot meet the overall weight of the rock-filled embankment, the ground bed 1 is treated, Replacement or compaction treatment.

[0035] The bearing capacity of the ground subgrade Among them, r i is the compacted weight of packing material of type i; h i In order to design i kinds of filling heights, including the converted height of the traffic load; [δ] is the allowable bearing cap...

Abstract

The invention provides a construction method of a stone-filled embankment, and belongs to the technical field of highway engineering. The construction method of the stone-filled embankment comprises the steps of ground foundation bed treatment, surveying and setting out, roadbed stone filling and edge covering soil filling, geotextile and geomembrane laying, pipeline burying and soil roadbed layerlaying, and finally pavement structure layer laying on the soil roadbed layer. According to the construction method of the stone-filled embankment, the geotextile and the geomembrane are arranged, water on the upper portion of the roadbed is isolated, water on the upper portion of a road surface is prevented from entering the stone-filled roadbed to scour joint filling aggregates in gaps of the stone-filled roadbed, and the overall stability of the roadbed is guaranteed. Several pipelines are arranged above the geomembrane so that water at the upper part of the roadbed can seep into the pipelines and is intensively discharged into the excavated drainage ditches in the two sides of the roadbed, the soil roadbed layer plays a role in protecting the structure of the stone-filled roadbed through drainage of the water at the upper part of the roadbed, and the overall stability of the roadbed is further protected.

Description

technical field [0001] The invention belongs to the technical field of highway engineering, and in particular relates to a construction method for filling stone embankments. Background technique [0002] There are many roadbed filling materials, but all kinds of filling materials have relatively high requirements on the external conditions. In addition to the quality requirements of the soil material itself, the subgrade filling of soil filling materials is also affected by the external climate, which restricts the speed of subgrade filling; sea sand filling materials have little impact on the external climate but have high requirements for slope stability protection. And there must be sufficient material sources; stone filler is less affected by the external climate than soil filler, and has a wider source of material than sea sand filler, but the porosity between fillers is large, and water will greatly damage its quality. [0003] The filler in the stone-filled subgrade ...
