A kind of ocean engineering squeezes into tubular pole with fibre-reinforced plastics
The present invention relates to a kind of ocean engineerings to squeeze into tubular pole with fibre-reinforced plastics, be particularly suitable for anticorrosion and
The demanding harbour of shock resistance, harbour, marine drilling platform, bridge, ocean cushion cap etc..
Existing tubular pole of squeezing into is mainly steel-pipe pile and timber in ocean engineering field, and steel-pipe pile is by ocean hurricane, seawater
Salinity, wave, ice, which melt, alternately to be attacked, perishable, greatly reduces the service life of stake, maintenance cost is high, furthermore steel-pipe pile weight
Amount is big, and transport installation is inconvenient, long construction period；Timber intensity is low, impregnates be easy to rot in the seawater, service life is short and easy
Pollute environment.Above-mentioned Marine Engineering Steel tubular pole and timber structure itself the deficiencies of there are perishable, weight is big, pollution environment it
Summary of the invention
For deficiency existing for existing Marine Engineering Steel tubular pole and timber, it is an object of the invention to propose a kind of use
Service life is long, reduce transport and the ocean engineering of installation cost squeezes into tubular pole with fibre-reinforced plastics.
The purpose of the present invention is realized using following technical scheme.A kind of ocean engineering proposed according to the present invention is fine
Dimension enhancing composite plastic squeezes into tubular pole, and pile body includes the structure sheaf made of fibre-reinforced plastics, is coated on structure
The basis material of the HDPE wear-resistant protecting layer of layer outer surface, the fibre-reinforced plastics uses polyurethane resin, strengthening material
Material uses unidirectional fiber bundle and continuous fiber felt.
Further, the fibre reinforced composites make pile body by pultrusion molding process or winding shaping process
Further, the section of the pile body is circle, a diameter of 100-1600mm.
Further, the wall thickness of the pile body is 10-80mm.
Further, the inside of the pile body can inject concrete mortar.
Tubular pole proposed by the present invention has corrosion-resistant characteristic, and long service life, and light-weight can greatly reduce lifting weight
Amount reduces the requirement to crane ship；Use scope is extensive simultaneously, can be used as the bumper piles of harbour, harbour, ocean platform load-bearing
Stake, stake of controlling flood, offshore wind generating foundation pile etc.；Compared with steel-pipe pile, native tubular pole, low cost, economic benefit is very considerable.
The above description is only an overview of the technical scheme of the present invention, in order to better understand technological means of the invention, and
It can be implemented in accordance with the contents of the specification, and to allow above and other objects, features and advantages of the invention can be brighter
Show understandable, it is special below to lift preferred embodiment, and cooperate attached drawing, detailed description are as follows.
Detailed description of the invention
Fig. 1 is the schematic diagram that a kind of ocean engineering of the present invention squeezes into tubular pole embodiment with fibre-reinforced plastics.
Fig. 2 is tubular pole scheme of installation proposed by the present invention.
[main element symbol description]
1- pile body 101- structure sheaf 102-HDPE wear-resistant protecting layer
Collet 3- vibrating hydraulic piling machine 4- soil at the top of 2-
It is of the invention to reach the technical means and efficacy that predetermined goal of the invention is taken further to illustrate, below in conjunction with
Attached drawing and preferred embodiment squeeze into its tool of tubular pole with fibre-reinforced plastics to a kind of ocean engineering proposed according to the present invention
Body embodiment, structure, feature and its effect, detailed description is as follows.
Referring to Fig. 1, a kind of ocean engineering of the present embodiment squeezes into tubular pole with fibre-reinforced plastics, pile body includes adopting
With the structure sheaf 101 of fibre-reinforced plastics production, it is coated on the high density polyvinyl-chloride protective layer of structure sheaf outer surface (i.e.
HDPE wear-resistant protecting layer 102).The basis material of the fibre-reinforced plastics is using high-intensitive, wear-resistant and impact-resistant
Polyurethane resin, reinforcing material use unidirectional fiber bundle, continuous fiber felt, knot are made by extrusion forming or winding shaping process
Structure layer can overcome the shortcomings of that steel-pipe pile is perishable and weight is big, wooden pipe stake is perishable and the service life is short, improve the anti-corrosion of pilework
Corrosion can and impact energy absorption performance, effectively improve the service life of pilework, energy conservation and environmental protection and reduce offshore engineering money
The use in source, greatly reduces installation cost.It certainly in other embodiments of the invention can be as needed in polyurethane resin
Add fire retardant, ultraviolet inhibitor etc..
The section of pile body is circle in the present embodiment, and a diameter of 100-1600mm, wall thickness 10-80mm exist certainly
It can according to need the shape and size of adjustment pile body in the other embodiment of the present invention.
It is prefabricated in the factory tubular pole when construction using fibre-reinforced plastics, molding is simple, and tubular pole can be according to ocean engineering
Need to customize diameter, pipe range；Then prefabricated tubular pole is transported to construction site, since resin based composite plastic is with easily molded
Remarkable advantage, can be needed that pile body cut using cutting machine according to in-site installation or pipe is carried out using hand paste process
The splicing of stake；Then since tubular pole has very superior pile drivability, using existing vibrating hydraulic piling machine 3 and it is mounted on pipe
Pile body 1 can be squeezed into soil by the top collet 2 in stake top portion, without developing new mechanical equipment.Furthermore in of the invention other
It can according to need in embodiment and inject concrete mortar inside pile body 1.
The above described is only a preferred embodiment of the present invention, any person skilled in the art is not departing from
Within the scope of technical solution of the present invention, any simple modification made to the above embodiment, equivalent according to the technical essence of the invention
Variation and modification, all of which are still within the scope of the technical scheme of the invention.
