Title:
STRUCTURE OF RIGID FRAME BRIDGE HAVING ABUTMENTS AND CONSTRUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/237678
Kind Code:
A1
Abstract:
A structure of a rigid frame bridge having abutments and a construction method therefor, wherein the structure of the rigid frame bridge having abutments comprises a girder (1) and a guide beam (2); a thin-walled main abutment (3), a bearing platform (4) and a pile foundation (5) are successive provided below a connection part of the girder (1) and the guide beam (2); a side of the bearing platform (4) and the pile foundation (5) near the girder (1) is provided with a conical slope (6); a soil-retaining secondary bridge abutment (9) is provided below a connection part of the guide beam (2) and a butt strap (11); a side of the soil-retaining secondary bridge abutment (9) near the butt strap (11) is filled with soil filling (14) behind the abutment; a plurality of successively connected butt straps (11), and a sleeper beam (12) disposed below an expansion joint (7) between the butt straps (11) are provided behind the guide beam (2); and light materials (10) are filled between the thin-walled main abutment (3) and the soil-retaining secondary bridge abutment (9). The thin-walled main abutment (3) uses a light and thin-walled structure that may fully absorb the deformation of the girder (1) so as to reduce the influence of the force on the abutment, and may effectively reduce shearing damage to the abutment and prevent the butt straps (11) behind the bridge abutment from settlement, thus ensuring smooth and comfortable driving.
