Problems solved by technology

[0004] The purpose of the present invention is to provide a maintenance column for the connection part of the viaduct, so as to solve the problem that the existing viaduct proposed in the above-mentioned background technology requires maintenance personnel to check the connection of the viaduct body and the supporting pier in the suspended state during the maintenance process. For maintenance, the maintenance personnel are bound by the rope for a long time, which may easily cause hypoxia and dizziness of the maintenance personnel. At the same time, the rope connected to the maintenance personnel is easily affected by the wind and swings back and forth under the influence of the wind force, which is not convenient for maintenance.

Abstract

The invention discloses a maintenance railing for viaduct connecting parts. The maintenance railing comprises a plurality of supporting piers supported and fixed on the ground, wherein a viaduct bodyis fixedly supported and placed at the top ends of the supporting piers; triangular supporting frames in a circle are fixedly installed on the surface of the top outer walls of the supporting piers; threaded holes are fixedly formed in one side outer walls of the plurality of triangular supporting frames; two fixing bolts are inserted into the threaded holes; one ends of the plurality of fixing bolts penetrate the inner walls of the triangular supporting frames and are in threaded connection with the middle outer walls of the supporting piers. According to the maintenance railing for the viaduct connecting parts, a plurality of the threaded holes in a circle are formed in the middle walls of the supporting piers and are combined with fixing bolts, the triangular supporting frames are easily installed on the surface of the viaduct body, a plurality of elliptic steel frames with different diameters are conveniently welded, installed and fixed with the top of the triangular supporting frames by a welding machine, and finally, a temporary maintenance platform capable of supporting activities of maintenance workers is formed.

Description

technical field [0001] The invention relates to a maintenance fence, in particular to a maintenance fence for a connection part of a viaduct. Background technique [0002] Viaduct: A type of bridge, generally referring to a bridge spanning a deep ditch canyon in place of a high embankment, and a bridge spanning a road in urban bridges, supported by tall supporting towers or pillars. [0003] During the maintenance process of existing viaducts, maintenance personnel are required to maintain the connection between the viaduct body and the supporting piers in a suspended state. The maintenance personnel are bound by ropes for a long time, which may easily cause the maintenance personnel to be dizzy due to hypoxia. The rope connected to the maintenance personnel is easily affected by the wind and swings back and forth, which is not convenient for maintenance, and the rope is easily broken due to the wear and tear of the viaduct pier. Contents of the invention [0004] The pur...
