Rubber dam features

No lap rubber dam Features:

1, the canvas directly to withstand the tension, improve the overall strength of the dam bag conditions, greatly improve the weft pull capacity, an increase of the safety of the dam bag;

2, the overall good, water flow pulsating pressure reduction, improve the seismic performance, to prevent the crest when the water, causing resonance dam bag was destroyed.

3, dam bag a molding, the overall quality greatly improved, anti-fatigue, resistance to flexor better, improve the life of the dam bag. Under the same conditions, the internal pressure ratio can be increased by 0.1 to 0.2, dam bags, civil construction are the corresponding savings. And because of the increase in internal pressure ratio, the dam can be more robust, to avoid the bag is too soft and prone to folding (concentrated erosion) and vibration phenomenon, the dam overcurrent uniform, the landscape effect is good.

4. Dam bag as a whole, the same thickness, no pad flat film, but also save the cost of raw materials and installation costs.

5, dam bag as a whole, the surface without joints, anti-puncture ability greatly improved, greatly reducing the damage caused by floating debris dam bag and tear the probability of tearing.

6, to avoid a joint rubber dam human factors interference, dam bag quality is more stable.

7. Can be mechanized installation, greatly reducing the labor intensity, improve work efficiency, save installation costs and installation time.

Compared with a seams rubber dam:

◆ has a joint rubber dam body permanent deformation, the dam due to the presence of lap joints produce uneven phenomenon, poor water, seriously affect the aesthetics of the dam.

◆ anti-puncture ability is very poor due to floating objects over the dam caused by the dam bag puncture and tear a great chance

◆ Dam bag is not a whole composition. Anti-fatigue, poor resistance to interference, short life, easy to crack, Alice skirt.
