TECHNICAL SEMINAR ON STEEL SHEET PILE
WHAT IS STEEL SHEET PILING?
Sheet pile is a hot-rolled structural shape with interlocks on the flange tips. The interlocks permit individual sections to be connected in order to form a continuous steel wall which is earth tight and virtually water resistant.
WHY ARE THERE SO MANY DIFFERENT SHEET PILING SECTIONS?
Different producers have different profiles and different interlock systems. All of the available sections, however, can be broken into two types based on end use. The most common end use requires sections which resist bending moment. This requirement for beam strength, or section modulus, is provided by "Z-profiles" and "U-profiles". The second end use is for sections which require interlock strength.
HOW LONG WILL SHEET PILING LAST?
With proper engineering and maintenance you can expect steel sheet piling walls to give you a very long service life. There are examples of sheet piling structures installed prior to 1920 that are still in service and performing well.
WHAT IS THE AVAILABILITY OF SHEET PILING?
In most cases sheet piling is readily available either from mill rollings or stock. For the availability of particular sections and specifications contact .For them to efficiently handle your inquiry you should have available the required sections, lengths, approximate quantities, steel specifications, and your desired delivery schedule.
Typical sheet piling lengths required for projects range from 15 to 70 feet. Some projects require much longer lengths, perhaps in excess of 90 feet. Contact member companies for availability of this longer length material.
SHEET PILING IS PRODUCED TO WHAT SPECIFICATIONS
Sheet piling is available to several ASTM specifications. ASTM A328 with a yield point of 39 ksi is the original ASTM sheet piling specification. Most sheet piling is currently produced to ASTM A572-Grade 50 and it is also available in Grades 60 and 65. For atmospheric weathering applications it is available to ASTM A588. For increased corrosion resistance in the splash/tidal zone in a marine environment it is available to ASTM A690. Both A588 and A690 have yield points of 50 ksi.
WHO INSTALLS SHEET PILING STRUCTURES?
In most areas you will find foundation contractors who specialize in pile foundations, including steel sheet piling installation. It is very important that the contractor retained to install your wall be experienced in using sheet piling.
WHAT ARE THE ADVANTAGES OF HOT-ROLLED SHEET PILING?
Hot rolled steel sheet piling is an engineered product meeting ASTM specifications. These specifications, and the producer's QC program, provide a quality product which is both ductile and durable. In addition, steel's strength will not change over the years, i.e., the material produced today will have the same properties during the entire life of the structure when properly maintained.
CAN I PLACE VERTICAL LOADS ON SHEET PILING?
Yes! There is the tendency to view sheet piling as a structural system used only to carry lateral loading from soil and water pressures. In fact, there is no reason that sheet piling can't be designed to carry both lateral and vertical loads. It is of course necessary for the engineer to insure, as with H or pipe piles, that the underlying soils can support the vertical loads.
WILL THE SHEET PILING INSTALLATION CREATE GROUND HEAVE?
Steel sheet piling, as compared to a closed ended pipe pile, has very little cross-sectional area. It is, therefore, a non-displacement pile which does not cause soil heave or cause additional lateral pressures on nearby existing walls.
WHAT IS NOISE FROM PILING WORKS?
Noise from piling works is one of the many types of construction noise. Piling works are mainly divided into percussive piling and non-percussive piling. Percussive piling means driving a pile into the ground by means of hammering or other percussive means with great force, so the noise generated is extremely loud. Non-percussive piling (such as bored piling) does not involve hammering and produces less noise. It is therefore not as disturbing as percussive piling.How long is sheet piling rolled?
