Inclined overhanging type supporting and retaining structure

Abstract

The invention provides an inclined overhanging type supporting and retaining structure which comprises at least two overhanging piles which are partially buried in a canyon slope surface and are arranged at intervals in the length direction of the canyon slope surface, the overhanging piles are arranged upwards in an inclined mode relative to the horizontal plane, a soil retaining plate (bearing plate) is arranged on every two adjacent overhanging piles, and the area between each soil retaining plate and the canyon slope surface is a fill area. The fill area is of a solid structure or a spacedsupporting column structure. According to the supporting structure, the terrain characteristics of a steep canyon are fully utilized, the overhanging piles are obliquely and upwards arranged on the slope surface of the canyon relative to the horizontal plane to form an overhanging structure, the section size and the length of the overhanging piles can be effectively reduced, and the constructioncost is reduced; the problems that under the steep canyon terrain condition, filling is difficult, the size of a retaining structure is large, the retaining height is limited, and the occupied area islarge can be effectively solved. Meanwhile, the riverway can be effectively prevented from being invaded along the riverway section, and the risk of underwater construction is avoided.

Description

technical field [0001] The invention belongs to the field of rock and soil, and in particular relates to an inclined cantilever support structure. Background technique [0002] In the complex landforms of mountainous areas, the terrain of steep canyons is more typical. To build roads under such terrain conditions, bridges and tunnels are used to pass through, and the project cost is relatively high; roadbeds are used to pass through, and it is extremely difficult to excavate the roadbed against the mountain due to the steep terrain. , the road alignment is usually widened to the side of the canyon. After the widening, the roadbed filling method will be used, which will form a tall fill slope embankment. The overall stability of the embankment is poor, and it will occupy a large area. It will encroach on a large area of ​​the river along the river, which will have a great impact on the environment and does not meet the environmental protection requirements. Vertical retainin...
