Embodiment approach

[0014] figure 2 It is another embodiment of the present invention: a plurality of multi-suspended tower cable-stayed bridges are connected to each other at the main tower 2, and only one main tower 2 is reserved at the connection point of each two bridges, which is shared by the two bridges. The root of each main tower 2 falls to the ground, and there is a foundation underground. The lengths of the multi-suspended tower cable-stayed bridges that are close to each other are not equal, and the number of sub-towers 3 of each bridge is not required to be equal. The purpose is to prevent live loads from occurring. cause system resonance. Each bridge top cable 1 is fixedly connected at each bridge link point. When the route of multiple suspended tower cable-stayed bridges turns, guy wires must be installed on the outside of the corner. If the corner is large, the corner should be decomposed into several smaller angles, and a guy wire should be installed on the outside of each corn...

Abstract

The invention discloses a multi-suspended-pylon cable-stayed bridge and aims to provide a bridge for constructing a larger span and is suitable for linking multiple bridges for constructing an over-long distance bridge or used for constructing an elevated trackway transportation system and more suitable for constructing a small and medium size bridge. The multi-suspended-pylon cable-stayed bridge comprises a plurality of branch spans with different heights, top cables 1, bottom cables 6 and force transmission cables 4, wherein the plurality of branch spans consist of suspended branch pylons 3 and are added in the middle part of the cable-stayed bridge; the top cables 1 are fixed to two main pylons 2 and the tops of all branch pylons and sagged in the shape of a fold line; the bottom cables are fixed to the root parts of all the branch pylons; the bottom ends of the force transmission cables are fixed to the bottom ends of all the branch pylons, and the top ends are fixed to the top of a closest branch pylon or a main pylon towards the direction of a closest main pylon; and the top ends of all stayed-cables 5, the bottom ends of which are uniformly fixed to a girder 6, are all fixed to the top of a closest branch pylon or a main pylon facing towards the direction of a closest main pylon.

Description

technical field [0001] The invention relates to a construction method of a suspension bridge, in particular, it consists of a top cable which is installed on the top of each suspended sub-tower and the main tower in the middle of the bridge deck and hangs down in a broken line shape, and is installed on one side of each suspended sub-tower and the main tower. A bridge composed of force transmission cables, cable-stayed cables and other components, that is, a cable-stayed bridge with multiple suspended towers. Background technique [0002] The long-span bridges that have been built today are basically cable-stayed bridges. The basic feature of the cable-stayed bridge is that the structure is relatively simple, and the geometric dimensions of the main tower, cable-stayed cables and other components increase in proportion to the increase of the span. At present, the size of large cable-stayed bridges has approached the limit, and it is extremely difficult to build cable-stayed...
