Der Bau von Stahlrohrpfahl mit Betonfüllung

Stahlrohrpfahl muss die Spezifikationen der American Society for Testing Materials für geschweißte und nahtlose Stahlrohrpfahl erfüllen.

Stahlrohrpfahl mit offenem Ende muss einen Nennaußendurchmesser von mindestens zehn und drei Viertel Zoll haben. Die minimale Nennwanddicke für Durchmesser kleiner als 14 Zoll muss 0,25 Zoll betragen. Die minimale Nennwanddicke für Durchmesser von 14 Zoll oder mehr muss 0,375 Zoll betragen.

Stahlrohrpfahl, das mit geschlossenen Enden angetrieben werden soll, muss ein Stahlende von genehmigtem Design haben. Der minimale Nennaußendurchmesser beträgt zehn und drei Viertel Zoll. Die minimale Nennwanddicke für Durchmesser kleiner als 14 Zoll muss 0,125 Zoll betragen. Die minimale Nennwanddicke für Durchmesser von 14 Zoll oder mehr muss 0,20 Zoll betragen. Wenn die Wanddicken unter diesen Werten liegen, gelten die Pfähle als Ortbetonpfähle.

The Construction of Pipe Piles Filled with Concrete

Pipe piles shall comply with the specifications of the American Society for Testing Materials for Welded and Seamless pipe piles (A252-55).

Pipe piles to be driven open-ended shall have a minimum nominal outside diameter of ten and three- fourths inches. Minimum nominal wall thickness for diameters less than 14 inches shall be 0.25 inch. Minimum nominal wall thickness for diameters of 14 inches or more shall be 0.375 inch.

Pipe piles to be driven closed-ended shall have a steel end of approved design. Minimum nominal outside diameter shall be ten and three-fourths inches. Minimum nominal wall thickness for diameters less than 14 inches shall be 0.125 inch. Minimum nominal wall thickness for diameters of 14 inches or more shall be 0.20 inch. If wall thicknesses are less than these values, the piles shall be considered as cast-in-place concrete piles.

The future of Steel Sheet piles

Grand Piling constantly developing and enhancing the range of steel sheet piles. By 2018 some new families of Z type sheet piles will be introduced .Also value added services as design services, crimping and welding of steel sheet piles , painting and application of sealant will be offered.

Within the coming years we will establish a full range of U and Z type sheet piles, from light to heavy, to strengthen their global position as a manufacturer of steel sheet piles.

Pile pile pipe inlet end of highly weathered soft rock softening

Pile pile pipe inlet end of highly weathered soft rock softening:

Pile pipe into the water are:

  1. From the poor welding quality of the pile joints and the lower opening directly into the pile tip of the open pile, into the pile core plugs do not have water-resistant capacity.
  2. Pile end plate welding is not strong, eccentric hammer or bias weld cracks, seepage from the cracks into the pile pipe inside.
  3. As the hammer to the end plate and the prestressed tendons anchor loose, and cracks.
  4. In the course of hammering and static pressure, the pile body will produce cracks that penetrate through the pile wall. The hammer peening hammer standard shall reach the end bearing layer, the final penetrating degree or the final 1m pile hammer number as the main control index . The final pressure standard of static pressure pile construction should be considered in consideration of factors such as pile length, pressure value, geological condition and regional experience.

Pile pipe into the water leading to the end of a strong weathering rock softening problem Wuhan area of strong weathered rock mainly refers to the mudstone and sandstone. The saturated uniaxial compressive strength after softening of the pile-end bearing layer is greatly reduced after the water-in-pipe, and this problem must be paid full attention.
