Embodiment 1

[0017] Embodiment 1 uses clamp I (such as figure 1 shown) fixed

[0018] Proceed as follows:

[0019] ① Cast the sacrificial anode 1 on the upper and lower core strips,

[0020] ② Weld two core strips with sacrificial anodes 1 into two half-rings 2 connected up and down,

[0021] ③ Weld the upper hinge 4 and the conductive clip 5 at one end of the two half-rings 2 connected up and down, weld the earring 9 and the reinforcing plate 8 at the other end, and weld the feeder rod 6 and the suspension ring 7 on one of the half-rings 2,

[0022] ④Send it underwater, insert the bolt 3 into the earring 9, and fasten the two half-rings 2 on the steel pipe pile.

Embodiment 2

[0023] Embodiment 2 uses clamp II (such as figure 2 shown) the fixing steps are as follows:

[0024] ① casting the sacrificial anode 1 on the core strip,

[0025] ② Form the core strip into a half ring 2,

[0026] ③ Weld earrings 9 and reinforcing plates 8 at both ends of the two half-rings 2 respectively,

[0027] ④Send it underwater, fasten the two half-rings 2 on the steel pipe piles with bolts 3.

Abstract

The present invention provides a fixing method of steel pipe pile sacrificial anode. It is characterized by that the sacrificial anode can be fixed on the steel pipe pile by means of collar clamp. Said invention also provides the concrete operation steps of said sacrificial anode fixing method.

Description

technical field [0001] The invention relates to an underwater fixing technology of a conductive element. Background technique [0002] At present, the underwater fixing of the sacrificial anode on the steel pipe is welded, and the construction is very difficult, which seriously affects the welding quality; even if the jet drainage is used for welding, the gas blocks the line of sight, which still affects the welding quality. Contents of the invention [0003] The purpose of the present invention is to provide a non-welding fixing method for the sacrificial anode of the steel pipe pile. [0004] The invention provides a method for fixing sacrificial anodes of steel pipe piles, which is characterized in that the steps are as follows: [0005] ①Fix the sacrificial anode 1 on the core strip according to the height of the sacrificial anode, [0006] ② Connect the required number of core strips with sacrificial anodes 1 to form a half ring 2, [0007] ③ Install connectors at ...
