Document Type and Number:
WIPO Patent Application WO/2024/074079
Kind Code:
A1
Abstract:
Disclosed in the present invention are a prefabricated assembled reinforced concrete retaining wall and a construction method therefor. The retaining wall comprises prefabricated vertical wall plates, prefabricated bottom plates, and a concrete connecting wall, wherein the vertical wall plates and the bottom plates are connected as a whole by means of the concrete connecting wall, which is cast in place; the vertical wall plates each have a variable cross section with the back of the wall forming a slope, and the individual vertical wall plates are longitudinally in tenon and mortise connection by means of joint tongues and joint recesses; an L-shaped rabbet is prefabricated at the bottom of a back surface of each vertical wall plate, and vertical wall plate stirrups, vertical wall plate tensile steel bars and vertical wall plate anti-shearing ribs extend from the rabbets; and bosses are provided on upper portions of the bottom plates of the retaining wall, tenons are provided on lower portions of the bottom plates of the retaining wall, and bottom plate anti-shearing ribs and connecting wall tensile ribs are embedded in the bottom plates of the retaining wall. In the concrete connecting wall, the bottom plate anti-shearing ribs are in lap joint with the vertical wall plate anti-shearing ribs, and the connecting wall tensile ribs are in lap joint with the vertical wall plate stirrups, such that on-site pouring forming is carried out. A scheme has a simple structure, has high on-site assembly efficiency and is outstanding in terms of cost performance, and has a wide application scope and popularization and application value in traffic engineering construction.
