Embodiment

[0017] Refer to attached figure 1 and figure 2 , the present embodiment provides a new retaining structure for road landslides, including a mouth-shaped pier 1, a door-shaped rigid structure 2 and an arch wall 3, and the door-shaped rigid structure 2 includes a first pile 21, a rear pile 22 and a pile top connection The beam 23, the first pile 21 and the rear pile 22 are arranged vertically in parallel with each other, and the upper ends of the first pile 21 and the rear pile 22 are fixedly connected by the pile top connecting beam 23 arranged horizontally, and the gate-shaped rigid structure 2 double-row pile structure is reasonable. The row spacing ranges from 3b to 5b (b is the pile side length), and the reasonable rise-to-span ratio of the arch slab ranges from 1:3 to 1:7.

[0018] The door-shaped rigid structures 2 are arranged at equal intervals in sequence along the same direction. The structures, specifications and materials of the door-shaped rigid structures 2 are ...

Abstract

The invention provides a new-type supporting structure for road landslide. The new-type supporting structure for the road landslide comprises mouth-shaped piers, door-type rigid frameworks and an archwall. The door-type rigid frameworks are successively distributed and arranged along the trend of a side slope, and the door-type rigid frameworks are parallel mutually. The neighboring two door-typerigid frameworks are fixedly connected through the arch wall. The outer sides of the two door-type rigid frameworks positioned at two ends are fixedly connected with the mouth-shaped piers. The new-type supporting structure is capable of solving problems that an anti-skid pile of a current supporting structure is disabled possibly, and lateral stability of a whole structure system is difficult tobe guaranteed, and belongs to the field of the supporting system improvement.

Description

technical field [0001] The invention relates to a novel support structure for road landslides, which belongs to the field of improvement of support systems. Background technique [0002] As a new support structure system, the portal-type rigid frame (pile-arch system) is developed on the basis of the portal-type double-row pile support structure. In the portal-shaped rigid frame (pile-arch system) support structure, the upper arch wall is responsible for the support of loose fill or strongly weathered rock mass, and completely transmits the soil pressure to the pile body through the arch wall between piles; the lower row of piles undertakes The remaining sliding force of the unstable rock mass, and the space structure composed of the portal rigid frame jointly resist the load behind the pile. [0003] According to relevant research data, there is a certain value range for the distance between anti-slide piles to form a "stress arch". Beyond this range, the "stress arch" bet...
