Problems solved by technology

The single-stage height of the existing anchor plate retaining wall is generally 6m. Due to the insufficient pull force of the tie rods and the multi-stage superposition combination is often used in the project, the overall stability is poor

Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0041] Such as Figure 1 to Figure 5 As shown in the figure, an anchor sheet pile composite structure is used to fix the filling body 4 to the stable bedrock 8 on one side of the slope, including three main components: the foundation pile 3, the concrete baffle 2, and the welded anchor 3. Slope design conditions such as upright, inclined or stepped grading on the side of the slope. The foundation pile 3 uses reinforced concrete poured on site to stabilize the bedrock 8 deeply and expose a small amount of the original surface, about 1m. The baffle plate 2 is connected to form the basis of the overall support. The depth, cross-sectional size, and reinforcement strength of the foundation pile 3 to penetrate into the stable bedrock 8 need to be determined through the stability calculation of the filling body shearing out along the bottom or the c...

Abstract

The invention discloses an anchor rod sheet pile combined structure and a method for reinforcing a high filling body on one side of a slope. The anchor rod sheet pile combined structure comprises an anchor rod (1), a concrete baffle (2) and a foundation pile (3), wherein the anchor rod (1) passes through a slope surface layer covering layer (6) to be connected with a stable bed rock (8) in a pouring slurry mode; an anchor head (9) of the anchor rod (1) is connected with the concrete baffle (2); the foundation pile (3) penetrates the stable bed rock (8) and is connected with the bottom of the concrete baffle (2); the part, in a filling body (4), of a rod body (11) of the anchor rod (1) is welded with short rods (10); the short rods (10) are arranged vertically and horizontally at intervals; the short rods (10) in the horizontal direction are welded and arranged on the upper part and the lower part of the rod body (11) at intervals; and the short rods (10) in the vertical direction are arranged on two sides of the rod body (11) at intervals. By the invention, the friction connecting capacity of the filling body and the anchor rod is greatly improved; the concrete baffle and the foundation pile are combined to form a stable and reliable system for retaining and reinforcing the high filling body on one side of the slope; the central height of the stable retaining filling body can reach 20 to 30 m; the manufacturing cost is low; and the application range is wide.

Description

technical field [0001] The invention relates to a retaining reinforcement structure and a construction method for a high fill embankment on one side of a slope. Background technique [0002] With the rapid development of western development and urban construction, there are more and more high-fill subgrade projects in the construction of mountain roads, railways and municipal projects. The main objectives of filling body reinforcement are slump and settlement stability control. Reinforced soil, grouting, dynamic compaction, gravel piles, bored piles, etc. are mainly used to enhance the strength and deformation resistance of the fill body itself, but it is difficult to be independently applied to the reinforcement of high fill retaining. The gravity retaining wall, reinforced concrete cantilever retaining wall, reinforced concrete cantilever retaining wall, (prestressed anchor cable) anti-sliding pile slab wall, prestressed anchor cable frame beam, anchor spindle slab retain...
