The problems such as source is in short supply, construction equipment lacks.In addition, milder metocean conditions are complicated and changeable, ocean engineering construction is also faced with construction window
The problems such as the of short duration, short time limit of mouth.
For first problem, patent document CN 204163069 U, CN106381833A and CN107447748A etc. are
It is proposed that being used using seawater marine sand concrete binding fiber enhancing composite material (FRP), forming FRP enhances seawater sea sand coagulation
Soil structure is applied in the construction of coastal and islands and reefs.But research shows that FRP not be completely immune to marine environment, it is especially right
Cost performance high glass fiber compound material and basalt fiber composite material.The performance of FRP is moved back under different ocean damp conditions
Change rate to differ widely, for example, FRP has IMAGE energy, this is mainly attributed in the environment of more dry environment
Its outstanding resistance to chloride erosion ability.But to still have long-term behaviour discrete big by FRP under hygrothermal environment and alkaline environment
Problem, this, which is mainly attributed to act on because of hydrone, leads to resin matrix hydrolysis, because of OH-Ion infiltration leads to fiber/resin interface
Inherent micro-/the microscopic damage such as unsticking and fibrous molecular structure destruction.It is well known that the humidity under marine environment is very big, and mixed
Solidifying soil is that overbased material (contains a large amount of OH-).Therefore, there is expected durability for guarantee FRP seawater marine sand concrete structure
Can, it need to guarantee that FRP is under conditions of relatively dry.
For second problem, the fabricated construction actively pushed forward in the engineering of land is a feasible solution party
Case still since the construction equipment in ocean engineering is relatively limited, must carry out light-weight technologg to lifting components.Very-high performance
Concrete (UHPC) material has many advantages, such as that intensity is high, anti-permeability performance is good, prepares prefab-form using it and can lower significantly and hangs
The weight for filling component can also play the role of completely cutting off outside moisture while own as permanent formwork, it is internal to reach guarantee
The dry purpose of concrete.Widely used steel bar girder superimposed sheet, which can be extended in ocean engineering, in the engineering of land answers
With, but its internal truss frame reinforcing bar is perishable, and can not be applied in combination with seawater marine sand concrete, needs to be replaced.
Therefore, to those skilled in the art, one kind how is researched and developed towards marine environment specific demand, bond material
Special execution conditions under self-characteristic and marine environment can be used with quick-assembling, seawater of gathering materials on the spot, sea sand, be had simultaneously
