Anchor rod gravity retaining wall for high slope support and manufacturing method

Abstract

The invention discloses an anchor rod gravity retaining wall for high slope support and a manufacturing method. A high slope comprises a rock surface which forms a steep terrain. The anchor rod gravity retaining wall comprises a stone-built retaining wall close to the rock surface, and a reinforced concrete plate strip layer with reinforced concrete rib columns is manufactured on the outer lateral surface of the stone-built retaining wall; the reinforced concrete plate strip is connected with a plurality of connecting anchor rods which obliquely pass through the stone-built retaining wall towards the inside and are straightly inserted in the rock surface. The manufacturing method includes steps that a) constructing the stone-built retaining wall, reinforced concrete plate strip and rib columns; b) drilling anchor rod holes in the rock surface and grouting; c) connecting steel anchor rods. The anchor rod gravity retaining wall for the high slope support combines the advantages of the gravity retaining wall and anchor rod retaining wall and reasonably uses rocks at the back of the retaining wall, one part of the pressure on the retaining wall is transmitted into the rocks, and the anchor rod gravity retaining wall for the high slope support is reasonable in structure, clear in stress, convenient to construct and suitable for the high slope support and the like of the mountainous area.

Description

technical field [0001] The invention relates to a bolt gravity retaining wall used for high slope support in steep terrain in mountainous areas and a manufacturing method thereof. It is mainly suitable for high slope support structures adjacent to rocky slopes in mountainous areas, and belongs to substation engineering construction technology field. Background technique [0002] Due to the limitation of mountainous terrain, the field leveling process of many substation projects often needs to "open mountains and fill valleys", resulting in the problem of high slope support. This kind of high slope problem often has three notable characteristics: 1. The free surface with a height difference greater than 10m is formed in a local area of ​​the site; 2. The back of the slope is very close to the rock; [0003] Currently applicable to such high slope support methods are gravity retaining walls, anchor retaining walls and reinforced earth retaining walls. The section of the grav...
