Anchor having fixing device at side of pressure plate to depress land slope and method of installing same

Abstract

The present invention relates to an earth structure for reinforcing a land slope and, more particularly, to an anchor having a fixing device at a side of a pressure plate to depress a land slope, andan installation method for installing the anchor on a land slope. A steel pipe-configuration friction-type fixing device integrated with a pressure plate of the anchor is installed at a side of the pressure plate, a primary packer is installed at the central portion of the anchor and an anchor front end side fixing device is fixed by implementing pressure grouting, then a large-scale pressure plate for depressing a land slope, together with a pressure plate-side fixing device, imparts tensile force to a tension member of the anchor to provide pressure, then a secondary packer is expanded, andsecondary pressure grouting is implemented, in order to provide an anchor having a fixing device on a pressure plate for depressing a land slope and preventing the loss of the tensile force of the anchor.

Description

technical field [0001] The present invention relates to a soil retaining structure for reinforcing a slope, and more particularly, to an anchor including a platen-side fixing body for compressing a slope and a method for installing the anchor in a slope. Background technique [0002] Generally, in civil engineering for constructing roads, railways, embankments, tunnel openings, apartment buildings, etc., cut slopes or embankment slopes often occur. In this cutting slope or embankment slope, sliding and erosion occur. In order to prevent landslides and erosion and to be in harmony with the natural environment, environmentally friendly slope reinforcement methods are required. [0003] The problem with the soil nailing method generally performed as a slope reinforcement method is that it has a structure in which the slope is reinforced only by the friction of the nails, so it needs to be performed with a larger number of nails than a structure that is reinforced using the ten...

AI Technical Summary

Problems solved by technology

Therefore, even when the anchor is installed when the slope is excavated and the slope is compressed using a large pressure plate, the pressure plate part sinks over time, so that the tension of the anchor is lost, and as a result, there is no reinforcement effect

[0006] In addition, in areas with distinct seasons, due to repeated freezing and thawing to soften the soil, the pressure plate subjected to continuous compression sinks, and as a result, the tension of the anchor is lost.
