Replacing and connecting structure of integral anti-collision wall with sideboard on elevated road and construction method of replacing and connecting structure

Abstract

The invention discloses a replacing and connecting structure of an elevated road integrated anti-collision wall with sideboards and a construction method of the replacing and connecting structure. The replacing and connecting structure comprises old and secondary sideboards and new sideboards. One side of the new side plate is connected with the old secondary side plate through a hinge joint, and the other side of the new side plate is provided with an anti-collision wall; the old transverse connection reinforcing steel bars of the old secondary side plates and the new transverse connection reinforcing steel bars of the new side plates are connected above the hinge joints; the hinge joint, the old transverse connection steel bars and the new transverse connection steel bars are filled with early strength concrete, wherein the old transverse connection steel bars and the new transverse connection steel bars are lapped above the hinge joint. During construction, the central isolation pier of the elevated road is dismantled; an old sideboard to be dismantled is cut; after completion, the ground jacking device starts to jack; after jacking in place, the ground jacking device extends out to serve as a temporary beam; a new side plate is erected after the beam erecting vehicle transversely moves in place; and after completion, the old sideboard to be dismantled of the next span is replaced, and meanwhile, transverse connection implementation and longitudinal connection seam treatment between the old sideboard and the new sideboard which are completed in construction are carried out. According to the anti-collision wall, the replacement time of the anti-collision wall is shortened, and viaduct traffic in the daytime is not affected.

Description

technical field [0001] The invention relates to the technical field of replacement of an elevated anti-collision wall, in particular to a replacement and connection structure of an integrated anti-collision wall with side plates on an elevated road and a construction method thereof. Background technique [0002] With the continuous advancement of the urban renewal process, the decline of the service level of the urban elevated buildings in the early construction and the aging of the component facilities have become increasingly prominent. As an important safety protection facility for bridges, the anti-collision wall is an important safety protection facility for bridges, due to the deterioration of materials year by year and the lack of functions caused by the update of design requirements. one of the key questions. [0003] In addition, the anti-collision wall, as an auxiliary facility, has a designed service life of 15-20 years, which does not match the design service lif...

AI Technical Summary

Problems solved by technology

For most cities at present, the urban viaduct is often an important artery of regional traffic, and it is unacceptable to interrupt the traffic for a long time to carry out the replacement of the anti-collision wall

[0006] In addition, the surrounding area of ​​the elevated is often a commercial-intensive area, the traditional large-scale machinery operation space is limited, and the construction efficiency is low, which will have a considerable impact on the environment and the quality of life of the surrounding people.
