Applications of Steel Sheet Pile:
Bulkheads–from small retaining walls for private marinas to large dry docks, ports, and other infrastructure projects
Cofferdams–temporary, in water or on land, to permit excavation for and construction of permanent works
Cut-off Walls–in connection with earth or concrete dams or dikes to retard seepage
Environmental Barrier Walls–for contaminant containment purposes
Temporary and Permanent Retaining Walls
Seawalls, Flood Walls, Dikes, Jetties, Groins
Navigation Lock Walls and other large navigation structures
Mooring and Turning Cells, Dolphins
Barge Docks–consisting of individual cellular structures
Bridge Protection Cells–to protect bridge piers from shipping collisions.
Bridge Abutments
Temporary or Permanent Below Grade Shoring–for basements and parking structures
Artificial Islands
Types of Steel Sheet Pile:
Steel sheet piling is manufactured in three basic configurations: “Z”, “U” and “straight” (flat). Historically, such shapes have been hot-rolled products produced at structural mills. Like other shapes such as beams or channels, the steel is heated in a furnace and then passes through a series of rolls to form the final shape and the interlock, which allows the sheet piles to be threaded together. Some manufacturer’s use a cold-forming process in which steel coil is rolled at room temperature into the final sheet pile shape. Cold formed sheet piles have hook and grip interlocks.
Grades of Steel Sheet Piling:
Sheet piling is specified by reference to the ASTM standard. The basic grade is ASTM A572 Gr 50, with many manufacturers producing ASTM A572 Gr 60 as the new standard.
Additional grades of steel for piling have been developed for possible use where corrosion is a consideration. ASTM A690 and A588 are 50 ksi (345 MPa) yield steels of a formulation which has demonstrated increased life. ASTM A690 has been shown to reduce the corrosion rate in the splash zone by 2 to 3 times. A588, also known as weathering steel, is resistant to corrosion in the atmospheric zone.
There are other proprietary steel grades, such as AMLoCor®, which has been shown to reduce the corrosion rate in the permanent immersion zone by up to 5 times.
The steel sheet pilegenerally has the material inspection and the appearance inspection, in order to correct the steel sheet pile which is not required, so as to reduce the difficulty in piling process.
(1) appearance inspection: including surface defects,length, width, thickness, end to rectangle ratio, flatness and the shape of the lock mouth, etc.. Need attention:
A, have influence on the welding pieces into the steel sheet pile should be cut off; B, cut hole and section defect should be reinforced:
The actual section thickness should be measured if C and steel plate piles are seriously corroded. In principle, the
Quality inspection of all steel sheet piles should be carried out
(2) material test: the chemical composition and mechanical properties of steel sheet pile base material are comprehensively tested.Including the chemical composition analysis of steel, tensile and bending test of
Components,locking strength test and elongation test.At least one tensile and bending test is carried out for each specification of steel sheet pile: two steel specimens per 20-50t weight should be tested.
