The Lifting construction at 80 meters height - Holmatro Statements
Currently, the bearings of Poyanghu Bridge, a 636-meter long cable-stayed bridge, have been damaged. According to Answers Shown Here , the mechanical state of the damaged bridge unfavorably deviates from the ideal style state, and the bridge must be repaired in time to restore its security and serviceability. However, compared with the bearing repair work of beam bridges, much less clinical and engineering ventures have actually been made in the history to direct the bearing repair work of cable-stayed bridges.
Through these works, it is discovered that the proposed repair work plans work in practical use. 1. Introduction, Bearing damages are typical structure illness for bridges in operation. If they are not fixed in time, the health of the bridges could be threatened. For bearing repairs of beam bridges, the jack-up approach is usually used.
A lot of clinical research studies and engineering applications recommend that the jack-up strategy is fully grown and appropriate to bearing repair work of beam bridges [15] Under operational loads and environmental deteriorations, the bearing damages can likewise be detected on cable-stayed bridges. Nevertheless, different from beam bridges, when the bearings on cable-stayed bridges stop working, the primary girders will be raised by the stayed cables near the broken bearings, causing the hazardous situations in which the primary girders and the bearings are separated.
However, compared to the bearing repair work of beam bridges, much less scientific research study studies or engineering endeavors have been dedicated to the bearing repair work of cable-stayed bridges to the writers' understanding. In July, 2019, bearing damages were observed on Poyanghu Bridge, a 636-meter long cable-stayed bridge. To repair the bearings, two innovative repair plans were proposed by practicing engineers, which are reported and numerically verified in this short article.

This article likewise reports the on-location monitoring of the bearing repair of Poyanghu Cable-stayed Bridge. Different from tracking of the bearing repair of beam bridges which usually focuses on the displacements of the beams near the bearings [13], the present tracking practice determined the forces of some remained cable televisions in comparison with the calculated arise from numerical designs.
