In reviews of a pneumatic caisson method in our country, there are many misunderstandings associated with periods and terms in books and reports. It is especially remarkable that these misunderstandings happened at the period which the pneumatic method was introduced to our country at the early period. Ninty two years was past since the pneumatic method with air lock was introduced to our country in 1899. It is unusual that a proper construction method has been used for a long time. These are caused by some reasons which are modification of the construction machines imported from the over sea at the early period, active application to field works, settlement of the design methods and introduction of high project management. In this report, the precise review of the development on the pneumatic caisson method is described on three parts which are the introduction of the construction methed, modificating process for the air lock and shaft, the design method and the project management.
