Spun pile is one of the types of piles are widely used in the world construction. Concrete poured down bore hole Wet concrete over spill at ground level.

Two cases can be considered for estimating axial pile capacity.
. A spun pipe pile is essentially an end-bearing variation of a traditional micropile without the central steel reinforcement Figure 4. Where fi inner unit skin friction Ai inner pile shaft area qp unit pile point end bearing A p end-bearing area of pile plug π d i2 4 di inner pile diameter. In one case the soil plug the soil trapped inside the pile is assumed to remain in place while the pile moves up in cookie cutter style around the plug and through the soil.
5 6 inch wall Typical Design Loads 250 to 800 tons Pile Properties High strength concrete fc 7 ksi f pe 12 ksi 16 ft long pile segments typical Segments combined and post-tensioned. Auger drilled into ground to required depth. Prestressed concrete cylinder pile is a special type of precast concrete pile with a hollow circular cross section.
Plugged Open-Ended These have a plug on the bottom end of the pipe. Hydraulic hammers are to be used to drive each pile to the required penetration length or the required set so as to provide the required load carrying capacity as pre-determined. Driving of the piles shall be continuous without interruption.
You saw around the pile remove the balance of concrete mechanically and use. In this case the a steel plate is welded to the lower end. Spun pipe piles are high strength 80 ksi steel threaded pipe sections that are drilled and socketed into bedrock and filled with grout.
We carry from 6 to 13 Flat or Cone StylePiling CapCovers perfect for your marine dock. PC Piles are column elements in the foundation that function to withstand and carry the load from the superstructure. The spun pipe pile gains axial compressive resistance.
This causes the soil inside the pipe to be a precise amount lower than outside the pipe. The range for subsea Levelling Tools is between 1600t to 3000t and supports pile ranges of 72 to 102. A brief comparison of these two types of piles is given to facilitate further discussion.
Ad Top Quality Made in USA Free Shipping to USAWe carry from 6 to 13 Flat or Cone Style. 31 Steel H-piles Steel H-piles commonly used in Hong Kong are Grade 55C 305305149 kgm 305305180 kgm or. By WIKA Beton PC Piles are designed with various sizes to withstand various types of structures.
Bottom Plate This is one of two common plugged piles. Specification for Precast Prestressed Spun Pile 3 April 2006 any damage to the pile. Steel reinforcement cage lowered in the bore hole with the upper lap length enclosed in PVC sleeve and sealed with sealant to ensure no bond between the reinforcemen t and the concrete above the pile cut-off level.
For open-ended pipe piles the following conditions are recommended to determine whether the pile is unplugged or plugged. Jacket Pile Grippers and Levelling Tools can be combined easily for a completely workable solution. The key element of driven pile design for uplift loading is the piles axial capacity.
Both steel H-piles and PHC piles are commonly used in Hong Kong while PHC piles are commonly used in Macau. Nowadays most people use spun pile foundation addition to precast concrete pile to construct most of the buildings and bridges. In trimming precast concrete piles whether prestressed or conventionally reinforced you dont cut the reinforcing.
Spun Cast Concrete Cylinder Piles Typical Sizes 36 42 48 54 66 inch OD. For above water use 200t 800t and 1600t units are available that are adjustable for all pile diameters.
