Embodiment Construction

[0038] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0039] Such as Figure 1 to Figure 4 As shown, a figure 1 As shown, a geotechnical bag bridge-type embankment structure, in the high-fill road section, adopts a geotechnical bag bridge-type embankment along the longitudinal direction of the road, and the embankment includes three parts: the pavement structure layer, the geotechnical bag subgrade and the backfill soil. *100cm*30cm, layered and staggered. Lining 9 is provided on the surface of the embankment slope to avoid direct exposure of ultraviolet rays to geotechnical bags. Concrete lining or ecological lining composed of local soil and local herbal plants can be used. The asphalt pavement 5 is laid on the top of the embankment, including a surface layer 6 and a base layer 7. The surface lay...

Abstract

The invention discloses a geotextile bag bridge type embankment structure and a construction method thereof. A geotextile bag bridge type embankment is adopted in the longitudinal direction of a roadin a high fill road section. The embankment consists of a pavement structure layer, a geotextile bag subgrade and backfill soil. The geotextile bag bridge type embankment structure not only improves the bearing capacity of the embankment but also saves geotextile bags. The geotextile bags on the backfill soil are reversely wrapped by geogrids so as to enhance the integrity. According to the principle of the method, under the action of upper loads on the geotextile bags, the tension of the bags can provide additional cohesion to soil masses in the bags so as to improve the integral strength andvertical bearing capacity of the embankment, improve the bearing capacity of the embankment, reduce differential settlement, reduce the amount of the geotextile bags and reduce the engineering cost.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a geotechnical bag bridge embankment structure and a construction method thereof. [0002] Background technique: [0003] With the development of our country's social economy, the number of vehicles owned by families has increased sharply. In recent years, our country has been continuously expanding and improving the construction of the transportation network. When the original road surface elevation of highway site selection does not meet the design elevation, it is often necessary to fill embankments above the original ground line to the design elevation. A large amount of fillers used to fill embankments are usually local soil and rocks nearby. In order to ensure the strength and stability of embankments, coarse-grained soils such as gravel soil and sandy soil with better grading are generally used as fillers. When the soil quality around the project area does not meet the req...
