The invention discloses a kind of novel fan basis sacrificial anode installation methods, including following installation steps: (1) with two blocks of semicircle steel plates for one group, the both ends of several sacrificial anode blocks being welded with two blocks of semicircle steel plates respectively, so make two groups of semicircular sleeve cages；(2) steel-pipe pile of non-installation of sacrifice anode block carries out pile sinking；(3) two groups of semicircular sleeve cages are transferred into bracket position close to steel-pipe pile, and is mated under water；(4) two groups of semicircular sleeve cages are mated by the set cage overall structure of composition using bolt and steel-pipe pile fastens；(5) electrical communication welding is carried out between set cage overall structure and steel-pipe pile pile body.Sacrificial anode block is welded more than the water surface with set cage, and the working strength that sacrificial anode block is welded below the water surface is reduced；Later maintenance, replacement are convenient, only need to unclamp connection bolt, when playing hanging sleeve cage, that is, peelable electrical connection weld, and integral replacing process working strength is smaller, reduces the labor intensity of worker.
Description
Technical field
The present invention relates to metal material anticorrosion fields, and in particular to a kind of novel fan basis sacrificial anode installation side
Method.
Background technique
The iron foot of sacrificial anode block is generally welded on steel when carrying out galvanic anode protection by blower foundation steel-pipe pile
On tubular pole.Application No. is 2012100321802 patents to provide for a kind of intertidal steel structure blower foundation sacrificial anode block peace
Dress technique implements welding using the leg and steel-pipe pile outer wall of sacrificial anode block and plays cathodic protection to blower foundation.Use this
Kind method replaces larger workload after having the drawback that corrosion, need to cut off sacrificial anode block and hang in new sacrificial anode again
Block carries out Underwater Welding, and construction intensity is big, and underwater visibility, the bottom of compared with, welding quality cannot be guaranteed；Using straight in land
It connects and welds the method that sacrificial anode block is driven piles again on steel-pipe pile, sacrificial anode block also can be in subsequent high-energy hydraulic vibration
It shakes and falls off during hammer pile driving by vibration.
Summary of the invention
To overcome defect of the existing technology, the present invention provides a kind of novel fan basis sacrificial anode installation sides
Method, by sacrificial anode block welding to the set cage being made of two blocks of steel plates, then by the set cage for being welded with sacrificial anode block transfer to
Steel pipe pile bracket position provides more effective solution scheme in order to solve the above problem.
The present invention adopts the following technical scheme that solve the above problems: a kind of installation of novel fan basis sacrificial anode
Method, which is characterized in that specific installation method includes the following steps:
(1) it uses two blocks of semicircle steel plates for one group, one end of several sacrificial anode blocks is welded to one of semicircle steel plate
On, corresponding be welded on another block of semicircle steel plate of the other end of several sacrificial anode blocks is one group of semicircular sleeve cage, is welded
Two blocks of half rounds plates of sacrificial anode block are axially symmetric, make two groups of semicircular sleeve cages according to the method described above；
(2) steel-pipe pile of non-installation of sacrifice anode block is subjected to pile sinking and squeezes into seabed；
(3) the semicircular sleeve cage inner wall of the good sacrificial anode block of two group weldings is transferred into bracket position close to steel-pipe pile, and under water
It is mated, two groups of semicircular sleeve cage bottom ends are supported on bracket and no longer glide；
(4) two groups of semicircular sleeve cages are mated by the set cage overall structure of composition using bolt and steel-pipe pile fastens；
(5) carry out electrical communication welding between set cage overall structure and steel-pipe pile pile body, four blocks of semicircle steel plates and steel-pipe pile it
Between be both needed to carry out electrical communication welding.
In above-mentioned technical proposal, wherein be provided with bolt hole on semicircle steel plate described in step (1).
Wherein, bolt described in step (4) is hinged bolt.
Wherein, three pieces of sacrificial anode blocks are welded on every block of semicircle steel plate, the sacrificial anode block welds six pieces altogether, and six
Sacrificial anode block described in block is equidistant and is welded on the set integrally-built outside of cage in parallel.
Wherein, the set cage, set cage and steel-pipe pile pad, set cage and sacrificial anode block welding point are not necessarily to additional anti-
Corruption processing.
Wherein, the height of steel-pipe pile pile sinking, set cage be installed on the height of steel-pipe pile according at blower position ooze absolute altitude,
High tide level water surface absolute altitude, low tide water surface absolute altitude are calculated.
The invention has the following beneficial effects: sacrificial anode block had not been welded when steel-pipe pile piling, drive piles when so driving piles
Smoothly, the risk that no spelter is fallen；Sacrificial anode block is welded more than the water surface with set cage, and solder joint is waterborne by moving under water,
Reduce the working strength of the water surface or less welding sacrificial anode block；Later maintenance, replacement program are convenient, need to only unclamp connection spiral shell
Bolt, when playing hanging sleeve cage, that is, peelable electrical connection weld, integral replacing process working strength is little, reduces the labour of worker
Intensity.
Detailed description of the invention
Fig. 1 is the structure diagram that set cage overall structure and steel-pipe pile of the invention weld ditch.
Wherein: 1, steel-pipe pile, 2, semicircle steel plate, 3, sacrificial anode block, 4, bolt, 5, bracket.
Specific embodiment
In order to deepen the understanding of the present invention, below with reference to embodiment and attached drawing, the present invention is completely described, is answered
Work as understanding, as described below is only exemplary embodiment of the present invention, limiting the scope of the present invention is not used to, in attached drawing
Shown in be only simplification view of the invention, so only show structure related to the present invention in attached drawing.
As shown in Figure 1, a kind of novel fan basis sacrificial anode installation method, specific installation method include the following steps:
