Taking the construc-tion of main pier platform of a certain of bridge as example,by comparing and selecting several schemes of foundation protection wall,the case description of densely covered steel tubular piles protection wall technics can provide some reference for similar engineering construction.

and adopting advanced cooling control process,tubular pile steel wires with good surface quality,high precision and excellent comprehensive mechanic property is produced.

Application of epoxy powder coating in anti-corrosion of steel pipe pile for the bridge cross over Hangzhou gulf;

Finite element analysis of the support of steel pipe pile composite soil-nailing wall;

The application of the method combined with manual hole digging pile and steel pipe pile in quicksand formation;

By the technological route of open-hearth-blooming-high speed rolling,pipe pile steel and its wire rod(both brands of 30MnSi,30Si2MnB)were developed.

Determining and improving the bearing capacity of steel tubular piles for piled wharfs has long been an issue that the engineering field has endeavored to study and solve.

When installing steel tubular piles in regions where granite is shallowly overburdened, the piles are easy to deviate and the pile tip is easy to warp, resulting in slow driving.
