Description
Technical field
The utility model relates to a kind of underwater piling construction pile crown guide frames, are suitable for Oversea wind power generation industry, sea
Upper petroleum industry and other coastal waters pilework marine structures.
Background technique
Currently, the rear underwater piling construction operation of pitching pile formula at sea wind-powered electricity generation jacket truss basis, offshore oil platform etc.
Has more application in marine structures.Generally for the underwater pile sinking operation of rear pitching pile formula, steel-pipe pile during the pile driving process, due to
Locating rack or locating sleeve are in underwater, often due to water flow and surge influence and disturbance, there are steel pipes during pitching pile is hung
The case where stake is not easy positioned in alignment casing.In steel-pipe pile decentralization process, steel-pipe pile pile lining is often directly contacted with internal surface of sleeve pipe, is held
It is also easy to produce pile lining abrasion.Meanwhile during piling, steel pipe stake body and the mutual stress of casing wall are easy to cause steel-pipe pile stake
Body damage, or even locating rack or locating sleeve are pullled into deformation, cause steel-pipe pile positioning deviation occur.
Utility model content
Technical problem to be solved by the utility model is: in view of the above problems, providing a kind of underwater piling construction
Pile crown guide frame is conducive to the quick positioning that pitching pile is hung.Meanwhile avoiding the direct of pile body and locating rack or locating sleeve
Contact, prevents pile body from wearing, and is conducive to the protection during driven piles to locating rack or locating sleeve.Used by the utility model
Technical solution is:
A kind of underwater piling construction pile crown guide frame, it is characterised in that: the pile crown guide frame is steel-pipe pile nose cone
Shape guide frame forms space combination structure, the pile crown by welding by full wafer guide plate, half guide plate, guiding reinforcing bar
Guide frame and steel-pipe pile pass through welded connecting.
On the basis of by adopting the above technical scheme, technical solution further below or right is also can be used in the utility model
These further solution pools use:
The full wafer guide plate of the pile crown guide frame is together with half guide plate vertical welding, in spatial clapboard type point
Cloth.
The guide plate of the pile crown guide frame is inserted into steel pipe pile head, and the pile crown guide frame is outside steel pipe pile head
The upper end of the part in portion omits radially protruding and forms the limit of pile crown guide frame insertion depth with steel pipe pile head and cooperate, and institute
State the guide plate portions arc transition of protrusion and its underpart.
The guiding reinforcing bar 3 of the pile crown guide frame and guide plate weld, and stretch out guide plate certain length, and with it is underwater
Positioning sleeve tube wall in piling construction forms guiding cooperation.
The beneficial effects of the utility model are: the utility model proposes a kind of underwater piling construction pile crown guide frame,
It solves pitching pile orientation problem in the underwater pile driving process of steel-pipe pile, pile body is avoided directly to contact when being inserted into piling location structure,
And pile body during piling can be further avoided and contacted with piling location structure.Have the advantage that 1) structure is simple, light weight
Change design, it is easy for installation.2) guiding reinforcing bar has certain flexibility, can make steel as far as possible on the basis of not destroying abutment sleeve
Tubular pole is in the center of abutment sleeve.3) guide plate is distributed in pile crown in cross partition, longitudinal to have certain length, Ke Yizeng
The soil plug effect of staking head, improves the bearing capacity of stake.
Detailed description of the invention
Fig. 1 is the top view of the underwater piling construction pile crown guide frame of the utility model.
Fig. 2 is the A-A sectional view of the underwater piling construction pile crown guide frame of the utility model.
Fig. 3 is the B-B sectional view of the underwater piling construction pile crown guide frame of the utility model.
Specific embodiment
Underwater piling construction pile crown guide frame provided by the utility model is steel-pipe pile nose cone shape guide frame, by full wafer
Guide plate 1, half guide plate 2, guiding reinforcing bar 3 form space combination structure, the pile crown guide frame and steel pipe by welding
Stake 4 passes through welded connecting.
As shown, the head of full wafer guide plate 1 and half guide plate 2 is cut by certain angle, full wafer guide plate 1
Head is in isosceles triangle shape, and half guide plate 2 is then its half, and the tail portion of full wafer guide plate 1 and half guide plate 2, which has, inserts
Enter portion 5, the rear end on head radially projecting 6, pile crown guide frame entire combination is at space cone structure.
The full wafer guide plate 1 of the pile crown guide frame is in cross point together with 2 vertical welding of half guide plate
Cloth.The cross diaphragm structure of the pile crown guide frame guide plate composition, is welded with 4 pile body lower end of steel-pipe pile.
Pile crown is goed deep into the insertion section 5 of the guide plate 1,2 of the pile crown guide frame, and the pile crown guide frame is in steel-pipe pile
The upper end of part outside pile crown namely the rear end on head radially projecting 6 and with steel pipe pile head formed pile crown guide frame insertion
Depth limit cooperation, can play stable and connection function.
It slightly being protruded outward in pile crown exterior section, prominent length is the thickness of steel-pipe pile, and guarantee is flushed with steel-pipe pile outer wall,
And it is excessive with guide plate taper-cut circular arc.
The guiding reinforcing bar 3 of the pile crown guide frame is parallel with guide plate lower end cutting line, is welded on 1 He of full wafer guide plate
On half guide plate 2, guide plate two sides respectively welds one.
As shown in Figure 2 and Figure 3, guiding reinforcing bar 3 the stretching guide plate 1,2 certain lengths of the pile crown guide frame, and and water
Positioning sleeve tube wall in lower piling construction forms guiding cooperation, and extension elongation is according to the flexibility and piling location for being oriented to reinforcing bar 3
The internal diameter of sleeve determines.
Certainly, above description is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
The those of ordinary skill in art field, in the scope of the utility model, the variation made changes addition or replacement, all should belong to this
The protection scope of utility model.
