Difficulty, multiple diagonal brace groups are from top to bottom equipped between two neighboring supporting steel pipe, and diagonal brace group is arranged in a crossed manner by two diagonal brace steel pipes
Composition, ensures the stable connection between two neighboring supporting steel pipe, further increases the supportive of support element group, make entire wind
It is firm that conductance pipe support more consolidates；It is hollow-core construction inside pipe casing, steel-pipe pile, which is inserted vertically to pipe casing, enters seabed, pipe casing
Upper end be equipped with the first horn mouth and the second horn mouth, steel-pipe pile plays the role of guiding when being inserted into, easy to operation, while just
Multiple connector sleeves being from top to bottom arranged are equipped between later stage grouting treatment, pipe casing and corresponding supporting steel pipe, it is more
Stable connection is played the role of in the setting of a connector sleeve between supporting steel pipe and pipe casing, prevents pipe casing and supporting steel pipe
Link position be placed in the connection effect that corrosion and damage occurs in seawater and both influences for a long time.
2, the both ends of diagonal brace steel pipe are respectively equipped with external member, and external member is sleeved on the outer wall of supporting steel pipe, ensure diagonal brace steel pipe with
Fastness of the supporting steel pipe in connection, the design is easy to disassemble, is readily transported.
