Problems solved by technology

[0003] However, since the two main cables are located in the center of the bridge deck and are not far apart, the space structure for anchoring needs to be turned to both sides of the main cables. The existing scatter rope sleeves cannot realize the lateral steering of the main cables, so that the main cables pass through the bulkhead. It is difficult to have enough anchoring space behind the noose, which cannot meet the requirements for lateral anchoring of the main cable

Embodiment Construction

[0014] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0015] Figure 1~3 The double main cable combined slack cable sleeve of the suspension bridge shown in , includes a sleeve body 1, a cover plate 2 arranged on the sleeve body 1, and two cable grooves 3 are arranged in the sleeve body 1 along the length direction of the sleeve body 1, The two cable grooves 3 are arranged side by side in the casing 1, and each cable groove 3 is arranged in a curve in the horizontal direction of the casing 1, the first cable groove 3.1 bends to one side of the casing 1, and the second cable groove 3. The two cable grooves 3.2 are bent to the other side of the casing 1; each cable groove 3 is also arranged in a curve in the vertical direction of the casing 1.

[0016] In the above technical solution, several vertical partitions 4 are arranged in each cable channel 3 .

[0017] In the above technical solution, it a...

Abstract

The invention discloses a combined splay cable sleeve for double main cables of a suspension bridge. The combined splay cable sleeve comprises a sleeve body and a cover plate arranged on the sleeve body, wherein two cable troughs are arranged inside the sleeve body along the length direction of the sleeve body; the two cable troughs are in parallel arranged inside the sleeve body; each cable trough is arranged in the form of a curve in the horizontal direction of the sleeve body; the first cable trough is bent towards one side of the sleeve body; the second cable trough is bent towards the other side of the sleeve body; each cable trough is arranged in the form of a curve in the vertical direction of the sleeve body. According to the combined splay cable sleeve, due to the arrangement of the two cable troughs, the two main cables are connected together, so that the horizontal linkage of the main cables is reinforced; and simultaneously, the two main cables are anchored in a splay manner by the splay cable sleeve, so that the anchoring space of the main cables is increased.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a double main cable combined loose cable sleeve of a suspension bridge. Background technique [0002] The scatter cable sleeve of the suspension bridge mainly plays the role of dispersing the main cable strands to facilitate the anchoring of the main cable. The existing scatter cable sleeves are fixed on a single main cable and can only disperse a single main cable. The direction of the main cable after passing the scatter cable sleeve is also No change, the slack is usually just fixed to the main line and floats with it. [0003] However, since the two main cables are located in the center of the bridge deck and are not far apart, the space structure for anchoring needs to be turned to both sides of the main cables. The existing scatter rope sleeves cannot realize the lateral steering of the main cables, so that the main cables pass through the bulkhead. It is difficult to have...
