A method for installing a vertical prestressed steel hoop concrete assembly retaining wall for highways

Abstract

The invention discloses a mounting method for a road vertical pre-stressed steel-reinforced concrete assembly type retaining wall. The mounting method specifically comprises the following steps: step1, digging a foundation ditch pit, and pre-embedding a PVC tube in the foundation ditch pit; step 2, uniformly coating a self-adhesive material to the surface of pre-stressed reinforcement; step 3, sleeving a ground anchor on the bottom of the pre-stressed reinforcement, and putting the pre-stressed reinforcement into the PVC tube pre-embedded in the step 1; step 4, grouting into the foundation ditch pit and the PVC tube; step 5, tensioning the pre-stressed reinforcement; step 6, coaxially sleeving hollow anti-collision steel hoop stand columns outside the tensioned pre-stressed reinforcement;step 7, connecting each anti-collision steel hoop stand column through a steel structure connecting plate; step 8, sequentially arranging moulding boards at the periphery of a linear type retaining wall, thereby forming a steel hoop guard bar; step 9, grouting into the steel hoop guard bar and the anti-collision steel hoop stand column; and step 10, performing tensioning and anchor-sealing on thepre-stressed reinforcement. The mounted retaining wall is good in impact resistance, and is low in construction cost.

Description

technical field [0001] The invention belongs to the technical field of concrete retaining walls for highways, and relates to a method for installing vertical prestressed steel hoop concrete retaining walls for highways. Background technique [0002] Beside some winding mountain roads, in order to prevent landslides from hindering road traffic, retaining walls are often set up on the side of the road to prevent earthwork from slipping. When installing existing retaining walls, a large amount of earthwork excavation is required. Concrete piers are poured in deep pits. This type of retaining wall setting method requires a large construction area, and because a large amount of excavation is required, the construction cost is high, time-consuming and laborious. In addition, the impact resistance of the existing retaining wall is poor, often There will be landslides and mudslides blocking roads and hindering traffic.
