Problems solved by technology

From pouring to stripping and walking, the technical clearance of a single section is long, and the time wasted in the combination of multiple sections is longer, resulting in a long construction period for the entire bridge
[0003] Even if it is a cross-rail device, it cannot realize the erection of water surface or canyon bridges with a span of more than 200 meters
In particular, many locations with harsh environments, wide waters, high and wide canyons, are affected by high winds, etc., so it is not safe

Abstract

The invention discloses a track cable pulling and supporting start-stop system. The track cable pulling and supporting start-stop system comprises two sets of supporting frames. Each set includes two supporting frames located at the two ends of an erected bridge respectively, a main rope is arranged between the supporting frames in each set, the two ends of each main rope pass through the tops of the corresponding supporting frames and then are anchored on the ground, the two main ropes are parallel, catwalks are arranged below the main ropes, the lower portion of each main rope is connected with a track through hoisting ropes, the tracks are arranged in the length direction of the main ropes, the two tracks are located in the same horizontal plane and are parallel, and a formwork system is arranged below the two tracks and comprises a cross beam and a plurality of formwork support systems hung on the lower portion of the cross beam. The construction length can reach the range within 2000 m, the construction speed is high, the technology is easy and convenient to implement, and the track cable pulling and supporting start-stop system is suitable for erection in high and wide positions of canyons with hostile environments and very wide water areas and also suitable for erection in canyons with a very high wind speed.

Description

technical field [0001] The invention relates to bridge construction equipment, in particular to a rail cable traction support opening and closing system. Background technique [0002] The prior art can only be completed by adopting multi-stage pouring on a section of bridge, and now one pouring can only pour about 2 meters long concrete. Due to the complex structure of the hanging basket, the hanging basket has many spare parts, which are interrelated with the bridge, and interspersed in the middle. From pouring to stripping and walking, the technical gap of a single section is long, and the time wasted in combining multiple sections is longer, resulting in a long construction period of the entire bridge. [0003] Even if it is a cross-rail device, it cannot realize the erection of water surface or canyon bridges with a span of more than 200 meters. In particular, many locations with harsh environments, wide waters, and high and wide canyons are affected by strong winds, m...
