我们将常规船舶下水安全气囊升级为超高压工程安全气囊。
Caisson moving airbags are designed based on rolling principle, largely used in port construction for cais-son moving. Using airbags as tools for caisson moving, it can avoid the track construction and mainte-nance and other complex process come from caisson moving by the hydraulic jacks.

南海沉箱拉移安全气囊展示
With the help of this new type of caisson moving airbags, we successfully moved a well-known ancient sunken ship of the Song Dynasty named "NanHai No. 1" for 400 meters intact horizontally from the beach to its permanent exhibition site within only two days in 2007, a sensational achievement that stunned the world at the time. Since then, caisson moving airbags has become the mainstream method in China and accounting for over 70% market share.
直径： Dia1 .0m 气囊是沉箱移动常用的气囊，对于较小尺寸的沉箱，Dia 0.8m 气囊是理想的气囊。
有效长度（Le）： 原则上，有效长度（Le）可以是沉箱宽度加0.5m。通常如果沉箱宽度>20m，安全气囊可以布置成两排。
安全气囊的工作压力： 机组实际承载能力=沉箱重量（G）/气囊总长度（Le x N1）。安全气囊的类别由最终的单位实际承载能力x 1.2的数字决定，然后以此数字参考安全气囊的规格表。 （N1代表沉箱体下的气囊件）
NO.s of Caisson Moving Airbags (N): The numbers of airbags for caisson moving is the pieces under caisson body (N1) plus the spare ones in front of the caissons (N2). The gap of airbags arrangement is about 2m under caissons, so N1=Length of Caisson (Lc)/2+ 1; the NO.s of spare airbags is decided by the distance of moving, and generally it should be more than 5 pieces.
