Description
Technical field
The utility model relates to a kind of offshore pile basis Anti-scouring structures using concrete platoon.Suitable for offshore and sea
Foreign field of engineering technology.
Background technique
Offshore pile basis is very widely used in coastal waters and marine engineering construction field, and application field mainly includes bridge
Engineering, Wharf Engineering and offshore wind farm engineering etc..
Since pile foundation changes periphery local flow field, can be generated around marine pile it is larger wash away, especially for large size
The diameter of marine project, pile foundation is increasing, and washing away problem also becomes increasingly severe, and the appearance of scour hole can not only be reduced
The bearing capacity of structure, influences stability；It also will affect structure frequency and influence sea simultaneously for washing away as fields such as offshore wind farms
Cable safety, to generate certain adverse effect to the operational safety of blower.Traditional jackstone method is anti-to pile foundation main structure
Rotten coating has certain destruction, and the movements such as jackstone is easy to happen drift under flow action, rolling moves, while jackstone method stone
Globality poor between block, environment friendly are poor.
Summary of the invention
Technical problem to be solved by the utility model is: in view of the above problems, provide that a kind of structure is simple, construction
Facilitate, adaptability is good, the good integrity offshore pile basis Anti-scouring structure using concrete platoon.
The technical scheme adopted by the utility model is a kind of offshore pile basis protection against erosion knot using concrete platoon
Structure, it is characterised in that: pile foundation suspends the concrete platoon for having muti-piece to be centered around around the pile foundation in midair through hanger；
The concrete platoon has the concrete block of several arrangeds in length and breadth, the concrete block in concrete platoon
Between through lateral nylon rope and longitudinal nylon rope be linked to be entirety, concrete block top surface is embedded with suspention nylon rope, the concrete block
Wire rope suspensioning through being connected on suspention nylon rope thereon is on the hanger.
Rubber spacer is lined between the hanger and the pile foundation.
The hanger is composed of several I-shaped steel type truss being criss-cross arranged, which is formed with can be with
Concrete block on the concrete platoon suspends otic placode in midair correspondingly, and suspention otic placode connects the wirerope.
Clearance filled small sandbag between the concrete platoon and the pile foundation.
The concrete platoon and concrete platoon intersection have overlay region, and overlay region range is 3~5 times of coagulations
Soil block length.
The design grade of the concrete block be greater than C15, concrete block block use prefabrication system, block spacing be 20~
50mm, with a thickness of 300~500mm.
The hanger upper surface is welded with several hanger otic placodes.
Connection is reinforced through interconnection nylon rope between the concrete block at concrete platoon edge.
The transverse direction nylon rope, longitudinal nylon rope, interconnection nylon rope and suspention nylon rope diameter are greater than 20mm.
The beneficial effects of the utility model are: if the utility model has dry concrete by hanger suspention around pile foundation
Platoon, structure is simple, installation is convenient.The utility model 1) adaptability is good, it is suitable for pile foundation different geological conditions nearby
With the engineering of different terrain variation；Good integrity, durability is good, and concret block is serially connected with each other by composite rope, erosion control
Component should not disperse；Construction efficiency is good, and basic processing and fabricating is completed by land, offshore construction excellent in efficiency, " single step " installation side
Offshore construction efficiency, save the cost is greatly improved in method.

Specific embodiment
As shown in Figure 1 and Figure 2, the present embodiment is a kind of offshore pile basis Anti-scouring structure using concrete platoon, pile foundation
Plinth has two pieces of concrete platoons being centered around around the pile foundation through hanger suspention.
As shown in Figure 3, Figure 4, concrete block of the concrete platoon with several arrangeds in length and breadth in the present embodiment, is mixed
It is linked to be entirety through lateral nylon rope and longitudinal nylon rope between concrete block in solidifying soil platoon, concrete block top surface is embedded with outstanding
Nylon rope is hung, reinforces connection through interconnection nylon rope between the concrete block at concrete platoon edge.
The intersection of concrete platoon and concrete platoon overlaps to form overlay region in this example, and the range of overlay region is 3~5
Concrete block length again.
Hanger is mainly composed of criss-cross I-shaped steel type truss in the present embodiment, and hanger upper layer is welded with hanger
Otic placode, lower layer are welded with suspention otic placode, and the pre-buried nylon rope above suspention otic placode and concrete platoon, which corresponds, to be arranged, pass through
Suspention nylon rope on wirerope connection suspention otic placode and lower concrete block.To avoid hanger to pile foundation surface layer antifouling paint
Destruction, hanger circular arc type part, with pile foundation contact surface post rubber spacer (see Fig. 5).
In order to improve pile foundation entirety protection against erosion ability, concrete platoon is used in combination with small sandbag, in pile foundation and is mixed
Small sand pocket is filled between solidifying soil platoon, small sandbag is along stake week uniform throwing.
