Abstract

The invention discloses a construction method of mutilevel overpass scaffold, comprising the following steps: building a bottom layer scaffold provided with steel frame doorways for vehicles and pedestrians to pass, checking and installing a deformation monitoring system, and carrying out a load pressure test on the bottom layer scaffold; building at least two layers of bridge scaffolds on the bottom layer scaffold, building box girder doorways for bridge construction on the bridge scaffold, installing the deformation monitoring system on the box girder doorway and carrying out comprehensive load test. The bottom layer scaffold is provided with the steel frame doorway so as to meet the passing demand of big traffic flow; each layer of the middle part can be provided with the mutually crossed box girder doorways in the same plane and can be provided with the mutually crossed box girder doorways in the vertical direction, therefore optionally carrying out construction according to requirements; the whole scaffold only needs to be built and removed once, not only shortening the building and removing time of the scaffold but also reducing the risk of building and removing the scaffold; and each level of bridge can be constructed at the same time, and therefore, the construction period is short and the construction cost is low.

Description

Construction method of scaffolding for multi-storey overpass bridge technical field The invention relates to a method for constructing an overpass scaffold, in particular to a method for constructing a multi-layer overpass scaffold suitable for simultaneous construction. Background technique In the prior art, when building a multi-storey overpass, mostly adopt firstly to build the bottom scaffold, build the first floor bridge scaffold on the basis of the bottom scaffold, lay the formwork, cloth steel bars, pour concrete, after the first layer of bridge is poured and formed, dismantle the second For the bridge scaffolding on the first floor, re-build the scaffolding from the ground to the height of the bridge on the second floor. After the second-story scaffolding is built, formwork is laid, steel bars are laid, and concrete is poured, and so on. The height of a bridge. Therefore, the scaffolding construction of this overpass bridge is suitable for separate construction on...
