Abstract

The invention provides a tower-beam thrust connection device and a self-anchored suspension bridge rapid construction method. The beam end resistor is fixedly installed on the beam end reserved steelplate in the tower beam thrust connection device, the tower end resistor is fixedly installed on the tower end pressure-bearing steel plate, and the beam end resistor is connected with the tower end resistor through a thrust conductor. The method comprises the following steps: step 1, synchronously constructing the main girder and the bridge tower of the side span; step 2, installing a tower-beamthrust connection device to temporarily connect the main girder of the side span with the bridge tower; step 3, synchronously constructing the main cable erection and the main beam installation; step4, detaching the tower beam thrust connection device to complete the first system conversion; step 5, pulling the boom, removing the bracket, and completing the second system conversion. The method ofthe invention adopts the tower beam thrust connection device to realize the cooperative installation of the main cable and the main beam safely and economically, thereby greatly saving the field operation time; Its characteristic is to increase the system conversion of the main girder by one time compared with the traditional process.

Description

technical field [0001] The invention belongs to the field of roads and bridges, and relates to a self-anchored suspension bridge, in particular to a tower-beam thrust connection device and a rapid construction method for a self-anchored suspension bridge. Background technique [0002] The self-anchored suspension bridge is different from the general ground-anchored suspension bridge. It does not require huge anchors. The main cable is anchored at the end of the main girder of the side span. The main girder bears the horizontal and vertical components of the main cable, which solves the geological problem. Conditions do not allow the construction of anchorage and the problem of building a suspension bridge, and retains the graceful shape of the traditional suspension bridge. [0003] Since the main cable of the self-anchored suspension bridge is directly anchored on the main girder, the main cable will generate a huge horizontal component force during the construction process...
