Embodiment 1

[0075] This embodiment provides a kind of tower-anchor-pier-anchor combined rapid construction method of a self-anchored suspension bridge, such as Figure 1 to Figure 9 As shown, the method adopts the combination of the tower beam thrust connection device 13 and the pier beam thrust connection device 14 to build a self-anchored suspension bridge;

[0076] The structures of the tower beam thrust connection device 13 and the pier beam thrust connection device 14 are identical;

[0077] The method includes the following steps:

[0078] Step 1, synchronous construction of side span main girder 6 and bridge tower 7;

[0079] Step 1.1, carry out foundation treatment to the foundation of bridge tower 7 and bridge pier 12, construct bridge tower 7 foundation, bridge pier 12 foundation, bridge tower 7 and bridge pier 12;

[0080] Step 1.2, set the side-span support 11, construct the side-span main beam 6 on the support 11, and complete the construction of the side-span main beam 6; ...

Abstract

The invention provides a tower anchor-dock anchor combined rapid construction method for a self-anchored suspension bridge. The method comprises the following steps: step 1, synchronously constructinga main girder and a bridge tower of a side span; 2, installing a tower-beam thrust connecting device to temporarily connect the main girder of the side span with the bridge tower; 3, erecting a maincable and hoisting 60% of the number of the middle-span main beam segments, so that the horizontal component force exerted by the main cable on the main beam of the side span is jointly borne by the bridge pylon; 4, installing a pier-beam thrust connection device according to the method of the step 2 to temporarily connect the main girder of the side span with the pier; 5, hoisting the remaining middle-span main girder segments according to the method of the step 3, so that the horizontal component force exerted by the main cable on the side-span main girder is jointly borne by the bridge tower and the pier; 5, sequentially remove that pier-beam thrust connecting device and the tower-beam thrust connecting device, and completing the system conversion; and 6, tensioning the boom, dismantling the support, and completing the construction.

Description

technical field [0001] The invention belongs to the field of road bridges, and relates to a self-anchored suspension bridge, in particular to a tower-anchor-pier-anchor combined rapid construction method of the 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. Therefore,...
