Embodiment 1
[0049] For the rubber dam bag of this embodiment, refer to the attachment Figure 1-3 The rubber dam bag of this embodiment is suitable for water-filled rubber dams. The dam bag has a height of 1.5m, a bottom length of 16.9m, an internal pressure ratio of 1.25, a slope ratio of 1:0.5, and a dam bag size: 6.084m× 21.3m, dam bag thickness 10mm;
[0050] When designing, according to the dam bag size 6.084m×21.3m, width plus 1%-2% shrinkage, length plus 5%-10% shrinkage, the design size is 6.2m×22.3m.
[0051] The rubber dam bag of this embodiment includes a dam bag body 1 composed of a lower rubber surface 5 and an upper rubber surface 6. The special feature is that a multi-layer skeleton layer is provided between the lower rubber surface 5 and the upper rubber surface 6. 7. The skeleton layer 7 includes a plurality of cords 2 spaced apart and arranged obliquely. The cords of the adjacent skeleton layers 7 have symmetrical cords. The lower rubber surface 5, the upper rubber surface 6 ...
Embodiment 2
[0071] This embodiment refers to the attached Figure 4-5 The difference between this embodiment and embodiment 1 is that the rubber dam bag includes a dam bag body 1 composed of a lower rubber surface 5 and an upper rubber surface 6. There are multiple rubber dam bags between the lower rubber surface 5 and the upper rubber surface 6. The skeleton layer 7 includes a plurality of cords 2 spaced apart and arranged obliquely. The cords of adjacent skeleton layers 7 have symmetrical cords. The lower rubber surface 5, the upper rubber surface 6 and the skeleton layer 7 are vulcanized Combined as a whole; both sides of the dam bag body 1 are provided with vulcanized airbags 11 integrated with it;
[0072] The installation process is different, the installation process of this embodiment is as follows:
[0073] 1), supplement vulcanization side airbag
[0074] Vulcanize the pre-vulcanized airbag 11 to both sides of the rim of the dam bag body 1;
[0075] 2), installation
[0076] The ope...
