ZD-Type cofferdam Performance and Application: ZD-Type cofferdam has the virtue of simplicity of operation, light weight, easy assemble, corrosion resistant, reliable seal and etc. It can be assembled according to the width of the channel and the depth of the water, and is mainly used in the water channel and water pump. It also can be used as permanent penstock to truncate the water flow when the pump station is under repair. Technical description: 　　1 When you install the cofferdam you should assure that the levelness deviation of the frame’s bottom sealing surface is less than 0.5/1000; 　　2 Before you install the penstock into the frame you should clean up the channel of the frame after you have installed it; 　　3 The penstock should move upwards and downwards freely without detention; 　　4 The infiltration capacity of the cofferdam is less than 0.02L/s•m.
