Existing sacrificial anode underwater welding method, has larger drawback: the reliability of (1) Underwater Welding is not high, and underwater visibility is lower, and the mode of the blind weldering of the diving many employings of welder, weldquality is uneven.(2) larger with inspection difficulty to the supervision of weld seam welding quality during Underwater Welding.(3) because of welding destroy steel pipe piling under water coating be difficult to good reparation, under water especially water turbidity when, coating coating difficulty is very large under water.(4) blind weldering is high to operating personnel's technical requirements under water, and Underwater Welding is large to operating personnel's labour intensity.
Summary of the invention
For overcoming the defect of prior art, the invention provides a kind of Novel steel pile tube sacrificial anode structure and installation method thereof, weld more than the water surface with steel pipe piling to realize sacrificial anode, improve the reliability of welding, reduce labor intensity, make coating damage be in more than the water surface simultaneously, be convenient to well repair coating.
Technical scheme of the present invention is: a kind of Novel steel pile tube sacrificial anode structure, by sacrificial anode and steel pipe piling weld by the water surface to be displaced downwardly to more than the water surface, steel pipe piling below the water surface is provided with semicircle anchor ear, every two semicircle anchor ear docking are together bolted on steel pipe piling later, the iron core bracket of sacrificial anode is welded on semicircle anchor ear on land in advance, described semicircle anchor ear and steel pipe piling are welded together by a round steel, one end of round steel is welded on semicircle anchor ear on land in advance, the other end extends to more than the water surface and welds with steel pipe piling.
The two ends of described iron core bracket are welded on adjacent semicircle anchor ear respectively, and described sacrificial anode and steel pipe piling be arranged in parallel, and form spacing.
The weld of the weld of described round steel and the weld of steel pipe piling, round steel and semicircle anchor ear, iron core bracket and semicircle anchor ear is all through rotproofing.
Described semicircle anchor ear, iron core bracket, round steel all carry out rotproofing in advance.
An installation method for Novel steel pile tube sacrificial anode structure, comprises the following steps:
(1) on land the two ends of the iron core bracket of sacrificial anode are welded on respectively on the semicircle anchor ear be disposed adjacent;
(2) on the semicircle anchor ear being welded with iron core bracket, weld round steel, the other end of round steel upwards guides to the position of more than the water surface;
(3) by frogman, semicircle anchor ear is fixedly mounted on steel pipe piling, after every two semicircle anchor ear docking, passes through bolt tightening;
(4) the other end of round steel is welded on the steel pipe piling more than the water surface.
Advantage of the present invention is: sacrificial anode and steel pipe piling weld waterborne by transferring under water, welding quality and operating efficiency can be improved, the supervision of welding quality is more directly perceived with inspection, labour intensity can be reduced in addition, cost-saving, making coating damage be in more than the water surface simultaneously, being conducive to repairing because welding the steel pipe piling coating damage place caused.
