Problems solved by technology

Compared with the traditional horizontal reinforcement, the above two methods can greatly improve the strength and ultimate bearing capacity of the reinforced soil, but the above two methods increase the difficulty of construction when the embankment filling is paved and compacted layer by layer. The ribs will be biased or even deformed
It can be seen from the analysis that the above-mentioned three-dimensional reinforcement method is mainly aimed at improving the integrity of the filler, but it cannot effectively support the original soil and cannot improve the stability of the joint between the old and new fillers.
[0007] In summary, although the existing retaining walls have achieved good results under suitable engineering conditions, they still need to be improved in terms of changing the mechanical properties of the soil behind the walls, improving the stability of the walls, and green slope protection. place

Abstract

The invention relates to a three-dimensional reinforced rigid-soft composite ecological retaining wall and a construction method. The retaining wall is characterized by comprising an upper portion soft ecological retaining wall body and a lower rigid retaining wall body, wherein the upper portion soft ecological retaining wall body and the lower rigid retaining wall body are connected through anchor bars. All layers of filling materials of the upper portion soft ecological retaining wall body are connected through connecting buckle parts, and water draining pipes, the connecting and fixing ends of horizontal ribbing bodies and inclined tie bars are evenly arranged on the lower rigid retaining wall body. A wall heel of a foundation of the retaining wall extends backwards to the edge of a stable soil body, vertical reinforcing piles are arranged at the bottom of the retaining wall, the horizontal ribbing bodies are laid in the filling materials behind the retaining wall, the wall toe of the retaining wall is filled back with a wall foot pressing soil body, and vertical ribbing bodies are vertically arranged at the connection position between the filling materials behind the retaining wall and an original soil body. The retaining wall structurally combines the advantages of a rigid retaining wall and the advantages of a soft retaining wall, achieves ecological slope protection, reduces pressure of soil behind the retaining wall, enhances structural integrity and has good technical and economical benefits.

Description

Technical field [0001] The invention relates to a retaining wall structure, in particular to a three-dimensional reinforced rigid-flexible composite ecological retaining wall with a flexible ecological retaining wall at the upper part and a rigid retaining wall at the lower part, good overall stability and three-dimensional reinforcement And construction method. It belongs to the field of basic engineering and is suitable for retaining wall engineering of highway, railway, water conservancy, construction and other projects. Background technique [0002] Retaining wall refers to a structure that supports subgrade fill or hillside soil and prevents the fill or soil from deforming and losing stability. It has been widely used in supporting and retaining structures of highways, railways, water conservancy, and construction projects. [0003] Retaining walls are usually divided into rigid retaining walls and flexible retaining walls according to their stiffness. Rigid retaining wall r...
