Anti-slide pile-corrugated steel arch-pull anchor combination slope protection structure and construction method thereof

Abstract

The invention relates to an anti-slide pile-corrugated steel arch-pull anchor combination slope protection structure. The anti-slide pile-corrugated steel arch-pull anchor combination slope protectionstructure comprises an anti-slide pile, special-shaped anti-slide columns, base beams, corrugated steel arches, girts and anchor cables, namely the anti-slide pile is arranged between an embankment and a slope in a piled mode, the base beams are poured at the pile head of the anti-slide pile, the special-shaped anti-slide columns are formed on the base beams in a poured mode, the corrugated steelarches are fixed between the adjacent special-shaped anti-slide columns to form soil retaining structures, and the girts are grouted on the top surfaces of the special-shaped anti-slide columns, theanchor cables are piled in the girts and obliquely piled into a hard soil layer in a slope soil layer, and prestress is applied to the anchor cables. According to the anti-slide pile-corrugated steelarch-pull anchor combination slope protection structure, due to the presence of the corrugated steel arches, the outer side of a filling material for backfill is in an arc shape; due to the soil bodyarching effect, the shearing force of a soil body can be converted into pressure stress of the soil body, and by utilizing the characteristic that the compressive strength of the soil body is remarkably higher than the shearing strength, the slope stability and the anti-slide capability are improved; and meanwhile, the material loss and the work amount can be reduced, and the construction cost canbe remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of slope support, and in particular relates to an anti-slide pile-corrugated steel arch-tension anchor composite slope protection structure and a construction method thereof. Background technique [0002] Slope support refers to the support, reinforcement and protection measures taken on the slope to ensure the safety of the slope and its surrounding environment. The commonly used support structure types include gravity retaining wall and pile-type anchor retaining wall, etc. . Gravity retaining walls rely on their own weight to maintain stability. They are large in size and weight, and consume a lot of materials. They are also limited by the bearing capacity of the foundation when they are built on weak foundations; The row of piles has large section, deep embedding, small pile spacing, and poor soil stability between piles. [0003] Corrugated steel has excellent cross-sectional properties and has been w...
