Problems solved by technology

[0006] The present invention proposes a new type of sling replacement underpinning device aiming at the structure of the existing suspension bridge lug lug plate with only one lug hole reserved, which solves the problem of high construction cost and damage to the existing state of the bridge structure when the suspension bridge is replaced. Issues such as large impact, complex construction process, and great difficulty

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] Such as Figure 1~Figure 6 As shown, the one-side straddle-type temporary cable self-balancing push-type suspension bridge sling replacement underpinning device includes an inclined main cable, and a steel box girder 13 is arranged below the main cable, and the upper surface of the steel box girder 13 is An ear plate is provided, and several permanent cable clips are arranged on the main cable, the top end of the permanent sling is connected with the permanent cable clip, the bottom end of the permanent sling is connected with the ear plate, and the ear plate A pin hole is reserved;

[0032] A temporary cable clamp 1 is arranged on the main cable at the high end of the permanent cable clamp, and the middle part of the temporary sling 2 straddles on the temporary cable clamp 1 and extends downwards. Both bottom ends are connected with the temporary sling should...

Abstract

The invention discloses a straddle-type temporary cable self-balancing push-type cable change underpinning apparatus for suspension bridge cables and belongs to the technical field of maintenance andreinforcement engineering of civil engineering suspension bridges. The straddle-type temporary cable self-balancing push-type cable change underpinning apparatus for suspension bridge cables comprisesa main cable that is inclined; steel box girder (13) is arranged blow the main cable; lugs are arranged on the upper surface of the steel box girder (13); the main cable is provided with a pluralityof permanent cable clamps; the top end of a permanent cable is connected with each permanent cable clamp; the bottom end of each permanent cable is connected with one lug; each lug is provided with apinhole. The straddle-type temporary cable self-balancing push-type cable change underpinning apparatus for suspension bridge cables helps solve the problem that cables are difficult to change when each cable lug of a suspension bridge has only one hanging hole, the fact that multiple-point lifting is carried out change one cable is avoided, aerial operation quantity is low, construction is simple, and the line shape and internal force of existing suspension bridge main cables and stiffening beams are less perturbed.

Description

technical field [0001] The invention relates to a one-side straddle type temporary cable self-balancing push type suspension bridge suspension cable replacement underpinning device, which belongs to the technical field of civil engineering suspension bridge maintenance and reinforcement engineering. Background technique [0002] Suspension bridge suspension cables are one of the most easily damaged and most critical stress-bearing components in suspension bridge components. The design service life is only 20 years, while the design service life of suspension bridges is generally more than 100 years. The cable needs to be replaced at least 4-6 times. [0003] Compared with the installation of slings during bridge construction, there are no anchor roads and hoisting equipment available for the replacement of suspension bridges during service. There are problems such as uninterrupted traffic, high-altitude operations, and narrow construction surfaces, and there are problems suc...
