Abstract

The invention relates to a cast-in-place concrete beam support overpass construction safety device and a construction method thereof. The cast-in-place concrete beam support overpass construction safety device is characterized in that the cast-in-place concrete beam support overpass construction safety device comprises a plurality of steel pipe pile stand columns which are arranged on the two sides of a lane at intervals in the traffic flow direction, slideways arranged in the traffic flow direction, fixed to the steel pipe pile stand columns and connected with the multiple steel pipe pile stand columns, and protective plates installed on the slideways; the protective plates can slide along the slideways, and the protective plates are used for being arranged above the lane, so that traffic jam cannot be caused during cast-in-place beam construction, and potential safety hazards caused to road driving can be prevented.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a construction safety device for cast-in-place concrete beam supports and a construction method thereof. Background technique [0002] At present, when the bridge crosses high-grade highways such as national highways and expressways, due to the heavy traffic flow and heavy traffic pressure, the beam part is generally designed as continuous beam hanging basket construction or prefabricated beam erection construction, which can reduce the impact on traffic under the bridge. [0003] In related technologies, when the bridge is designed as a long-span and heavy-duty railway cable-stayed bridge due to the special geographical environment, when the side span uses concrete cast-in-place girders as anchor span girders, it is generally constructed with full-height brackets. When there are traffic requirements Generally, steel pipe piles are used for construction. [0004] How...
