Description

Walking channel for tied arch bridge access manhole

Technical Field

The utility model belongs to the field of bridge engineering professions, and particularly relates to a walking channel for a tied arch bridge to enter and exit a manhole.

Background

Along with the development of the transportation industry in China, high-speed railways and highways have become main transportation modes for people to travel. In the planning development of railways and highways, the situation of crossing over the iron or the iron often occurs, when the situation occurs, if the crossing distance is short, continuous beams or simply supported beams can be adopted for crossing, and when the crossing distance is long, tie bar arch bridges can be adopted for crossing.

The tie-bar arch bridge is also called a steel tube arch bridge or a basket arch bridge, and consists of a beam slab, arch legs, arch ribs and suspenders.

When the railway straddles the highway, the tie-bar arch bridge is mostly adopted for crossing, and because the tie-bar arch beam body beam end is solid and the cross section is a plurality of chambers, personnel need to enter from the outside when repairing the beam, and the tie-bar arch bridge is different from the conventional simply supported beam or continuous beam entering from the beam end. In order to ensure personnel to enter the beam for maintenance, a ladder or a channel is additionally arranged at the manhole, and the manhole is considered to be close to a highway and possibly exceed a railway fence sealing area (namely, the projection position is arranged outside the fence or right above the highway), so that the ladder is very inconvenient to enter and potential safety hazards exist.

A walking path for a tied arch bridge to enter and exit a manhole as described above, as a preferred embodiment, is a distance between the path and the bottom of the tied arch bridge of not less than 1.6m. Thus, the maintainer can walk in the channel by wearing the waist, namely, the maintainer can pass through the channel, and the normal use of the road under the bridge is not affected.

A walking path for a tied arch bridge manhole as described above, as a preferred embodiment, is provided with handrails on both sides of the tied arch bridge manhole. The arrangement of the handrails is convenient for the maintenance personnel to enter the manhole from the ladder stand.

A walking passage for a tied arch bridge to enter and exit a manhole is provided as a preferred embodiment, and a protective fence for ensuring personnel safety is arranged on the passage.

A walking channel for a tied arch bridge to enter and exit a manhole as described above is provided with reinforcing ribs to increase the load carrying capacity of the channel as a preferred embodiment.

Reinforcing ribs can be added at the positions of 1/2 and 1/4 of the channel length so as to increase the bearing capacity of the channel.

The walking channel for the tied arch bridge to enter and exit the manhole is used as a preferable implementation mode, and the outer surfaces of the channel and the cat ladder are coated with anti-corrosion layers.

The adopted anti-corrosion layer can be a zinc-impregnation anti-corrosion treatment layer, and the design of the anti-corrosion layer can prolong the service life of the channel.

The beneficial effects of the utility model are as follows: the walking channel for the tied arch bridge to enter and exit the manhole is arranged in a suspended manner, so that under the condition that the safety climbing of an maintainer is ensured, the normal passing of vehicles under the tied arch bridge is not influenced, and the maintainer can conveniently enter the box girder to overhaul.
