Steel shell slide system and construction method

Abstract

The invention relates to a steel shell slide system and a construction method. The system comprises a two-end suspension pouring beam, an embedded steel shell, a closed steel shell, a first sliding device, a second sliding device and a third sliding device, wherein the embedded steel shell is arranged on the lower portion of the two-end suspension pouring beam; the closed steel shell is arranged on the inner side of a notch of the embedded steel shell; the first sliding device is arranged on a flange plate of the two-end suspension pouring beam; the second sliding device is arranged on a web plate of the two-end suspension pouring beam; the third sliding device is arranged on a bottom plate of the two-end suspension pouring beam; the first sliding device, the second sliding device and thethird sliding device are connected with the closed steel shell; the closed steel shell moves to a notch portion of the embedded steel shell along the first sliding device, the second sliding device and the third sliding device; and the shape of the closed steel shell is matched with that of the embedded steel shell. The problems that in order to reduce influences to running of existing railways and roads in rotation construction, closure is carried out by a middle steel-shell method, and a notch of the steel shell is closed and cannot slide automatically can be solved, the notch of the steel shell is closed simply and conveniently, influences to the road below a bridge are minimized, safety is ensured, and the corresponding economic cost is reduced.

Description

technical field [0001] The invention relates to a slideway system, in particular to a steel shell slideway system, and also relates to a construction method of the steel shell slideway system. Background technique [0002] With the development of my country's economy, the initial formation and continuous improvement of railway and highway networks, in the construction of railways and highways, it is inevitable to encounter the problem that new railways and highways need to cross existing railways and busy highways. It is necessary to consider adopting a construction method that has little impact on the operation of existing lines. [0003] At present, jacking or swivel construction is usually used, and the choice should be made according to the site conditions. When the two sides are swiveled and closed in the middle, the closed section will still affect the operation of the road under the bridge. The steel shell method can reduce the impact on the road, but the welding of t...

AI Technical Summary

Problems solved by technology

When the two sides are swiveled and closed in the middle, the closed section will still affect the operation of the road under the bridge. The steel shell method can reduce the impact on the road, but the welding of the gap in the steel shell after the swivel is in place will still affect the bridge. Under the existing railway and highway operation problems, the automatic closing steel shell has the problem of difficult movement of the steel shell in the closed section
