| Abstract: |
| The shiplock of the Three Gorges Project is the largest inland shiplock in the world with the highest water head.To meet the requirements of water impoundment of the reservoir,the shiplocks No.1 and No.2 are constructed in two stages.With the support and help of all the relevant departments,Changjiang Institute has successfully solved all the relevant challenging technical issues of the shiplock construction with the tight construction schedule,and strict requirements in temperature control of concrete pouring,and overcome difficulties in installation and lift of the miter gates and conflicts between operation and overhaul of the shiplock,etc.It has provided many technical supports in solving challenging problems in terms of construction,maintenance and operation of the shiplock. |
