Embodiment Construction

[0019] Below in conjunction with accompanying drawing and embodiment the present invention is described further as follows:

[0020] Such as figure 1 , figure 2 and image 3 As shown, the light-duty high embankment structure of the mountainous steep slope section that is beneficial to disaster prevention includes a reinforced concrete pile foundation 1, a reinforced concrete cap 2 and a subgrade 3; the reinforced concrete pile foundation 1 is buried in a bearing soil layer or a rock layer; The reinforced concrete cap 2 is supported on the top of the reinforced concrete pile foundation 1 and connected with the reinforced concrete pile foundation 1;

[0021] The light-type high embankment structure of the mountainous steep slope road section disclosed by the invention, which is beneficial to disaster prevention, firstly crosses the road section of the conventional bridge structure through the roadbed form, which improves the disaster resistance of the road section and reduces...

Abstract

The invention discloses a disaster prevention mountainous steep slope road section light high-fill embankment structure and a construction method, belongs to the field of roads and aims to improve thedisaster prevention and reduction capability of a mountainous steep slope and a high-fill road section, and improve structural security of a key road section with mountainous traffic facilities and the capability of rapid traffic recovery under disaster conditions. The structure comprises a reinforced concrete pile foundation, a reinforced concrete bearing platform and a light soil roadbed, wherein the reinforced concrete pile foundation is buried in a bearing stratum; the reinforced concrete bearing platform is supported at the top end of the reinforced concrete pile foundation and connectedwith the reinforced concrete pile foundation; the light soil roadbed is filled and constructed on the reinforced concrete bearing platform. By adopting the structure, a road section that only a bridge can be constructed generally is changed into a roadbed structure mode, and an existing damaged bridge is repaired by using the structure, so that the stability of a steep slope embankment is improved, influence of a roadbed structure close to a river upon a river channel is avoided, and difficulties in roadbed filling of steep slopes, roads close to rivers and highfill road sections can be effectively solved, meanwhile, the area occupation is reduced, and by adopting the light high-fill embankment structure, the traffic insurance capability of a road section is greatly improved, and the whole service life periodic cost is reduced.

Description

technical field [0001] The invention belongs to the field of highways, in particular to a light-weight high embankment structure and a construction method for steep slopes in mountainous areas and high fill sections that are beneficial to disaster prevention. Background technique [0002] Mountain roads are laid out as belt-shaped buildings on the surface of mountainous areas, and are extremely vulnerable to geological disasters such as collapses, landslides, and debris flows. Especially for steep slopes and high filling road sections, one side is adjacent to mountains, and the other side is adjacent to rivers or cliffs. Since the place is a depression formed by the side of the river or cliff to the side of the mountain, the filling height is high and the transverse slope is steep. It is difficult to set up walls and form roadbeds, and usually only bridges can be erected to cross them. However, bridges are weak in disaster resistance. They are the key nodes of the project c...
