Description

Railway steel bridge without trace renewal construction method

The invention relates to a railway steel bridge seamless updating construction method, in particular to a light structure with high strength, which makes the railway steel bridge update construction more efficient, and the construction process does not require a facility to bridge, open a construction access road, and utilize existing railways. Exempting traditional construction methods from occupying a large amount of construction land or renting land, the old steel bridge or damaged steel bridge can be renewed, and the construction time of the train is blocked by the extremely short night train, and the railway steel bridge that restores the original bridge daytime railway transportation function has no trace. Update the construction method.

According to the general railway bridge after the use of the time, the corrosion of the old steel bridge will affect the safety of the train, so its steel bridge needs to be updated. However, some railway bridges are located in scenic spots with sightseeing value. Most of the construction sites are steep. The traditional lifting method can't overcome the difficulty of lifting. The equipment and steel bridge transportation are inconvenient to operate. It is impossible to drive directly to the site with mobile cranes to carry out steel beam lifting. In the course of construction, it is necessary to rent a large area of construction land, open a construction road, build a facility bridge or install a fixed crane beforehand, and increase the operation troubles, increase the construction cost, increase the construction period, and certainly destroy the beautiful The environment, as well as the disruption of railway transportation, have even completely impeded the convenience of transportation between residents and tourists, and it has also plagued the renewal of railway bridges in steel bridges. In view of this, the applicant has continuously researched and experimented, and Meng Mengsheng designed a railway steel bridge renewal construction method to make the railway steel bridge renewal construction more efficient and will not affect the normal vehicle traffic.

The main object of the present invention is to provide a non-marking renewal construction method for a railway steel bridge capable of rapid movement, so that the renewal construction of the railway steel bridge is more efficient, no need to build a facility bridge, open a construction road, and utilize the existing railway to eliminate the tradition. The construction method needs to occupy the trouble of the construction land or the leased land, and the old steel bridge or the damaged steel bridge can be updated without damaging the beautiful environment, and the daytime railway transportation operation of the original bridge can be restored by using a very short construction time.

The aforementioned railway steel bridge seamless construction method has a door type structure and a transport vehicle (which is an electric wagon of the railway bureau) that can be connected to the door type structure. By hauling the door structure to the steel bridge section to be renewed, the old steel bridge was lifted and transported to the construction site for temporary placement, and the new steel bridge was moved from the construction site to the construction section, and the new steel bridge was placed on the old steel. At the end of the bridge section, the railroad track laying and the pavement beam and vertical plate are completed, so that the renewal of the railway steel bridge is more efficient and will not affect the daytime railway transportation of the original bridge.

The aforementioned railway steel bridge has no trace renewal construction device, wherein the door structure is provided with a main beam, and the main beam is provided with a supporting beam, a hydraulic column foot and a suspension structure, and the supporting beam is horizontally placed on the oil during construction. Below the foot of the column, the main beam is raised by the hydraulic column foot, and the old steel bridge is lifted by the suspension structure, and the new steel bridge is placed in the original steel bridge section in reverse.

The aforementioned railway steel bridge has no trace renewal construction device, wherein the suspension structure is arranged above the main beam and can be displaced along the main beam to facilitate the suspension and transportation of the new and old steel bridge.

The aforementioned railway steel bridge has no trace renewal construction device, wherein the support beam is connected to the crane disposed above the main beam, and the support beam is controlled by the crane to be up and down and positioned between the rails.

The aforementioned railway steel bridge has no trace renewal construction device, wherein the suspension structure is a crane.
