Wherein:
The location is covered 2 and is the cap of inner bolt hole foreign side, and there are 2 fixedly screws of sacrificial anode 1 in the one outside;
By import anchor pole 4 respectively slip casting be when setting depth meets the demands, adopt the method for high-pressure slip-casting around importing anchor pole 4, to form slurry body 11, in order to improve network of rivers areal geology situation, reinforced soil layer hardness, and then improve the withdrawal resistance that imports anchor pole 4, reach the effect of anchoring underwater pipeline stabilizing.
Importing anchor pole of the present utility model and extension rod join strength are strong, can reinforce dense waterway net region weak soil layer basis rapidly by importing bolt grouting, have increased the anchoring withdrawal resistance.
