Prestress anchor cable buttress-type parapet suitable for rock substrate

Abstract

The invention discloses a prestress anchor cable buttress-type parapet suitable for a rock substrate, comprising a parapet base, a parapet panel and a buttress plate, wherein the parapet panel and the buttress plate are arranged on the parapet base; the buttress plate is arranged on the inner side of the parapet panel; an inclined duct is arranged in the buttress plate; the steel strand of the prestress anchor cable passes through a PVC (Polyvinyl Chloride) pipe in the inclined duct; an included angle between the inclined duct and a horizontal plane is 15-45 degrees; one end of the steel strand is connected with the anchor head of the prestress anchor cable on the outer side of the parapet panel; the anchor head is fixed on the outer side of the parapet panel by an anchor head mad pillar; and the other end of an anchor cable steel strand extends into a rock foundation drilling hole below the rear side of a parapet heel slab. In the prestress anchor cable buttress-type parapet, the prestress anchor cable is effectively combined with the buttress-type parapet, and the prestress anchor cable built in the buttress plate can be used for increasing the strength of the buttress plate. In addition, the parapet base, the parapet panel, the parapet plate and the rock substrate are tightly combined, and the limit skidding resistance force and topple resistance performance of the buttress-type parapet are improved.

Description

technical field [0001] The invention relates to an embankment protective retaining wall structure for rock foundations. Background technique [0002] At present, the buttress retaining wall has been widely used in filling embankment reinforcement and filling building foundation reinforcement and other projects. The buttress-type retaining wall is a reinforced concrete structure, which mainly relies on the frictional resistance between the retaining wall foundation and the foundation to balance the earth pressure on the back of the retaining wall panel due to the inner filling of the retaining wall. [0003] figure 1 The basic structure of the existing buttress-type retaining wall is shown, including retaining wall foundation 1, retaining wall panel 2 and buttress plate 5. The retaining wall foundation 1 is in the shape of a horizontal plate, the retaining wall panel 2 and the buttress plate 5 are placed on the retaining wall foundation 1, the retaining wall panel 2 is perp...
