Abstract

The invention discloses a multi-arch bridge erecting machine, which comprises a track, a sliding frame and a driving mechanism. The track is set on the inner side of the multi-arch bridge foundation. The sliding frame includes a column and a beam. One end of the column is slidably set on the track, and the beam is connected to the other end of the column. aisle. The driving mechanism is connected with the column to drive the sliding frame to slide on the track. The invention also discloses a method for erecting a multi-arch bridge. The above-mentioned multi-arch bridge erecting machine and multi-arch bridge erecting method first use the sliding frame as a support assembly platform to assemble the main arches one by one, and then use the sliding function of the sliding frame to transport the main girder to the design position. The main girder overcomes a series of problems in the construction of oblique-span multi-link arch bridges under the condition of limited site and the traffic below cannot be interrupted for a long time. It abandons the traditional method, simplifies the complexity, and improves the safety and efficiency of on-site construction. and reduce the amount of temporary structural work.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a multi-arch bridge erecting machine and a multi-arch bridge erecting method. Background technique [0002] With the rapid development of China's social economy, the original expressway capacity has been gradually saturated, and a large number of lines need to be expanded or double-tracked. Due to the development of the city, the construction land is becoming more and more scarce, and the choice of road routes is subject to more and more restrictions, and the roads that need to be expanded or double-tracked are very busy with traffic and cannot be interrupted. There are more and more cases where the viaduct line is diagonally spanned from one side of the original line to the other side. Due to the span and angle of the road, the span of the diagonal bridge is relatively large and the construction is more difficult. In addition, urban roads have higher and higher requ...
