Project Name: Repair of Gezhouba Dam
Engineering material: anchorage glue, reinforcement structural glue
Engineering time: 2014

August 14 Three Gorges navigation sector decided to Gezhouba Sanjiang on the approach channel of 15 by the pier for overhaul. Repair work to repair defects, improve the function, comprehensive upgrade Gezhouba Sanjiang channel depend on ship quality. This is also built more than 30 years, Gezhouba for the first time by the ship pier for centralized repair.
 Gezhouba Sanjiang on the right and left side of the approach channel has a total of 15 by the pier. Among them, the left side of the upstream ship lock on the 3rd, there are six by the pier; the right side of the upstream ship lock on the 2nd ship, there are nine by the pier. The top and side of each abutment shall be provided with a fixed mooring column for the berthing of the down ship. These rely on the piers from put into use has been more than 30 years, due to frequent use, rely on the top of the ship pier column serious wear, fracture, or even missing and so on.
 The focus of the overhaul includes the repair of the column post niche steel, the water side of the concrete repair, and will be paved concrete structure, updated 25 Department of columns and so on. The project will take the sub-construction methods to ensure that the ship navigation and construction of the two correct.
 Andemei use of specific reinforcement technology and products, the structure of the wear and tear with a single part of the repair and reinforcement to ensure that the foundation of the foundation of the dam is not shaken, as much as possible to increase their useful life.
