Existing sacrificial anode underwater welding method, has larger drawback: the reliability of (1) Underwater Welding is not high, and underwater visibility is lower, the diving welder modes that adopt blind weldering more, and weldquality is uneven.(2) during to Underwater Welding, the supervision of weld seam welding quality is larger with inspection difficulty.(3) steel pipe piling destroying because of welding under water coating is difficult to good reparation, and especially in the situation of water turbidity, coating coating difficulty is very large under water 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, to realize sacrificial anode and steel pipe piling welds more than the water surface, improve the reliability of welding, reduce labor intensity, make more than coating damage is in the water surface, to be convenient to coating well to repair simultaneously.
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 with more than being displaced downwardly to the water surface, semicircle anchor ear is installed on the steel pipe piling below the water surface, 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 weld 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 the water surface above and steel pipe piling welding.
Weld on adjacent semicircle anchor ear respectively at the two ends of described iron core bracket, and described sacrificial anode and steel pipe piling be arranged in parallel, and form spacing.
The weld of weld, iron core bracket and the semicircle anchor ear of described round steel and the weld of steel pipe piling, round steel and semicircle anchor ear all passes 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 of adjacent setting;
(2) on the semicircle anchor ear that is welded with iron core bracket, weld round steel, the other end of round steel is upwards guided to the position more than 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 are waterborne by transferring under water, can improve welding quality and operating efficiency, the supervision of welding quality is more directly perceived with inspection, can reduce in addition labour intensity, cost-saving, make more than coating damage is in the water surface, repair at the steel pipe piling coating damage place being conducive to causing because of welding simultaneously.
