Sheet pilesKD750/5 D62650 are to be as watertight as possible to create a dry KD750/7 D62635,KD750/7.5 D62677 environment for construction KD750/6 D62634,KD750/6.5 D62676 are work to take place. For the caisson, KD 750/7.5,KD 750/8 have virtually the same job. It is a structure built to help workers construct on top of water, such as building bridges.Cofferdam KD 750/9 is to change the path of the water into another route, so the construction team could start their work on the foundation and then the body of the dam itself, of course KD 750/5 could be any other kind of structures.
The KD750/8 D 62632,KD750/9 D62685 are also used on occasion in the shipbuilding. and ship repair industry. when it is not practical to put KD 750/6 ship in drydock for repair work or modernization. Construction workers who leave the pressurized environment of the KD750/6.5 must decompress at a rate that allows symptom-free release of inert gases dissolved in the body tissues if they are to avoid decompression sickness, a condition first identified in caisson workers, and originally named KD750/7.5,KD750/8,KD750/9 in recognition of the occupational hazard.
The trench sheet KD 750/5,KD 750/6 are used in bridge KD 750/6.5,KD 750/7 or any other structure in water. a dewatering solution is crucial to completing the project successfully. A cofferdam becomes KD750/7,KD750/6 uneconomical in cases where the plan area of the foundation work is small as compared to the depth of water. KD 750/7.5,KD 750/8,KD 750/9 such circumstances. KD750/5 would prove to be the most suitable.
