1. When one of the cofferdams sprang a huge leak, it was plugged with old mattresses.

2. When the cofferdams were finished, the engineers turned to the next task-stripping the canyon abutments to expose fresh clean solid rock.

3. The second phase cofferdam is an important retaining structure during second phase diversion period.

4. The other part is temporary cofferdam and the rear land - based connection project.

5. At present , steel boxed cofferdam has applied in the construction of cap in deep water widely.

6. However, people often apply to the decomposed steel cofferdam for the local stresses analysis and neglect the space effect, which can't really reflect the steel cofferdam's actual stress state.

7. The fact that the project of big cofferdam facing the ocean for the pump room is one of prerequisites for the site earthwork and the building constructions was significanthy shown in the paper.

8. Double - wall steel cofferdam is the important facility of bridges deepwater foundation.

9. A longitudinal concrete cofferdam was demolished by way of underwater controlled blasting.

10. The procedure of construction with earth-bag cofferdam is introduced for the open-cut foundation in deep water and sandy soil with a narrow space at Pier No.

11. Floatable arch cofferdam is presented to offer dry environment and keep the main function of a reservoir when the dam is strengthening and repairing.

12. Temporary projects include temporary cofferdam project and protection project of ancient relics.

13. In that excavation, however, the water was not drained from the cofferdam.

14. The canyon walls were finally clean, the abutments sculpted, the cofferdams in place.

15. The distribution of waders is irrelevant to benthal biomass in the wetlands insides cofferdam.

16. The distribution of waders is irrelevant to benthal biomass in the wetlands cofferdam.

17. This is aimed at providing an effective measuring method for such kind of cofferdam construction.

18. The plan selection and construction of construction trestle bridge and bored platform were introduced, and the construction methods of borehole and cofferdam were also presented.

19. This article analyzes and summaries the design and construction enclosing the mound type sand cofferdam.

19. Wish you will love and make progress everyday!

20. The distribution of waders is irrelevant to benthal biomass in the wetlands insides cofferdam. Water depth is also an important factor influencing waders' distribution.

21. The impervious technique of high - pressure gunite applied embankment cofferdam Project was introduced comprehensively.
