Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] refer to figure 1 , figure 2 , the embodiment of the present application provides a subgrade structure for slopes, including a plurality of load-bearing structures 10, which are buried in the slope body 1a at intervals along the toe line direction of the slope 1; retaining walls 20 are installed on the load-bearing structures 10 The subgrade panel 30 extends into the slope body 1a and is carried on the retaining wall 20. The subgrade panel 30 is arranged along the slope toe line; the subgrade filler 40 is filled between the retaining wall 20 and the slope surface 1b to support the subgrade Panel 30.

[0025] Most of the subgrades of traffic projects in mountainous areas are along valleys and rivers. Some sections have steep terrain, high fill and excavation slopes, poor engineering stability, and serious damage to the ecolog...

Abstract

The invention provides a subgrade structure for a side slope. The subgrade structure for the side slope includes a plurality of bearing structures, a retaining wall, a subgrade panel, subgrade filler,and the multiple bearing structures are embedded in a slope body in the direction of a slope toe line of the side slope at intervals; the retaining wall is installed on the bearing structures; the subgrade panel extends into the slope body, is loaded by the retaining wall and arranged in the direction of the slope toe line; and the subgrade filler is filled between the retaining wall and a slopesurface to support the subgrade panel. According to the subgrade structure for the side slope, the retaining wall is used for filling and slope closing, the subgrade panel is used for transferring road loads to the bearing structures through the retaining wall, the earth pressure behind the wall is reduced, safeties of a subgrade structure are consolidated, and the stability of a subgrade projectis improved. The use of the subgrade structure for the side slope can reduce the work amount of filling and excavation parties, reduce damages to the environment, is economic and environmental protection, and improve the economy and rationality of the subgrade structure.

Description

technical field [0001] The invention relates to the technical field of roadbed structures, in particular to a roadbed structure for slopes. Background technique [0002] Most of the traffic construction projects in mountainous areas are built along valleys and rivers, or tunnels are dug, or high-filling and deep excavation are performed, and the stability of the project is poor. At the same time, the amount of earth and stone excavation is large, and part of the waste residue is thrown into the nearby wasteland or river valley due to inconvenient transportation, which raises the river bed surface, squeezes the side, hinders flood discharge, and seriously damages the ecological environment. If the slope is out of balance, it will cause mudslides or landslides. The safety and environmental protection benefits are poor, and the cost performance is not high. It is not in line with the current trend of environmental protection, conservation and low carbon. Contents of the inven...
