The construction process for a rubber dam primarily involves two key aspects: first, civil engineering works; and second, the custom fabrication of the rubber dam bag. (1) Civil Engineering Works: Civil engineers are responsible for ensuring that all prerequisites for the rubber dam's construction are met. The specific civil engineering tasks involved mainly include excavating the foundation pit and embedding the necessary control and monitoring pipelines. (2) Custom Fabrication of the Dam Bag: When commissioning the dam bag, it is advisable to consult multiple manufacturers. A thorough analysis of their past performance and reputation should be conducted to ensure the quality of the dam bags; particular emphasis should be placed on verifying whether they hold state-issued product quality certificates and comprehensive quality inspection reports for the dam bags. Prior to production, the dam bag and its accompanying base gaskets must be manufactured in strict accordance with the design drawings. Upon completion and before leaving the factory, a rigorous inspection must be performed to ensure that all dimensions and specifications meet the design requirements.
When broken down into finer detail, the comprehensive construction process for a rubber dam consists of 16 distinct operational steps:

1. Foundation arrangement of bolt and lower clamping plate 

2. Concrete pouring

3. Complete upstream bottom plate

4. Complete downstream bottom plate

5. Concrete bottom plate completed Expanse bottom gasket 

6. Drilling

7. Waterstop in place

8. Dam bladder hoisting

9. Unfold dam bladder

10. Dam bladder unfolded in place

11. Tighten bolts

12. Installation completed

13. Apply butter to protect bolts

14. Plastic bag protection

15. Protect clamping plate bolt by concrete

16. Rubber dam when completed
