Document Type and Number:
WIPO Patent Application WO/2022/142193
Kind Code:
A1
Abstract:
A construction method for a large-span thin-wall concrete sound barrier pouring trolley. The construction method comprises the following steps: step 1, constructing foundations (9) on two sides of an existing line, and mounting steel rails (91) on the foundations (9); step 2, hoisting a pre-assembled travelling system; step 3, mounting a truss system, that is, transporting machined arch frames (1) to a construction site, hoisting the arch frames (1), and connecting upright posts (3) to connecting beams (4); and adjusting a jack (83) and an oil cylinder (62), adjusting the arch frames (1) and overturning sections (2) to designed elevations, mounting the subsequent arch frames (1) in sequence, and connecting connecting rods between the adjacent arch frames (1) after the arch frames (1) are mounted and adjusted; and step 4, mounting a bottom form on a top arch (11), binding steel bars, mounting side forms, performing concrete pouring, reducing the height of the arch frames by means of the jack (83) and the oil cylinder (62) after the designed strength of concrete is achieved, removing the bottom form, adjusting the height of the jack (83) to make travelling wheels (7) come into contact with the steel rails (91), and moving a trolley. The method is convenient for moving and constructing, and does not affect the passage of an existing line while meeting construction requirements.
