Wide Selection of Shapes and TypesSheet pile is available in a wide range of section modulus per meter of pile wall, ranging from 874 to 21,846 cm³/m. This allows selection of the most economical type of sheet pile to meet the design requirements and the intended construction method.

Superb Drivability and WatertightnessThe clearance between the two threaded interlocks is moderate enough to ensure both excellent drivability and reliable watertightness.

Features

(1) Quick construction: Dramatic reduction in the construction period

(2) Reliability for long-term use: Increases the safety factor and reduces the deformation of the wall using robust steel sheet piles

(3) Availability of long pile and deep embedment: Up to 38m in length

(4) Sustainability: Remove and reuse possible(5) Availability of narrow areas

Advantages of steel sheet piles over other methods (masonry, RC walls, etc.)

Small-scale excavation

Large-scale excavation

The vertical load in the axial direction like a crane load is applied and the bearing force against the vertical load

is expected. Welding can't be carried out near the site.

Example of solution proposed by us

We want to use our land to the utmost. Can you provide a good steel sheet pile?

Do you have any steel sheet pile method that is environmentally friendly?

Do you have a steel sheet pile that can be easily installed?

Can you provide a good method to build a large-scale revetment for reclamation?

We want to minimize defl ection for safety when the front of a steel sheet pile is excavated. Can you provide a good steel sheet pile?

● Each pile of a wall has a uniform shape and rigidity. Therefore only one type of piling machine is required for installation and the sequential installation in the same direction is possible. This leads to easy installation. (Refer to pages 15 and 16.)

● This is a gravitational wall featuring a cylindrical shape assembled with straight web-type sheet piles. Inside is filled with sand. It is excellent in structural stability.● A prefabricated sheet p i l e ce l l me thod can provide quick construction. (Refer to pages 17 and 18.)

● Unlike a concrete-based temporary earth-retaining wall, the steel sheet pile wall can be repeatedly used and is environmentally friendly. In construction, sludge is not generated, and the disposal of soil is not required. (Refer to pages 13 to 16.)

● The moment of inertia is almost twice as large as that of Z-type sheet pile. This leads to reduction of defl ection and the number of struts.● The sheet piles can be re-used multiple times. (Refer to pages 15 and 16.)

● The clearance between the threaded interlocks is moderate enough to make it easy to install sheet piles which are installed afterward while pipe piles are installed forward. This clearance can absorb the inaccuracy of the positioning of pipe piles and sheet piles. (Refer to pages 23 and 24.)

● This is a gravitational wall in which steel sheet piles are installed in two rows. The tops of the sheet piles are connected by tie rods. And the space between the sheet piles are fi lled with sand. It is excellent in structural stability.● By dividing the construction site into multiple zones and by pairing a group of ships, the construction lead time can be reduced.

The steel sheet pile is a good method to construct a revetment quickly. The special function required to

construct the revetment for reclamation is the stability against waves until the completion of reclamation.

The structure must be safe even without back reclamation.

Depth of approx. 10 m － 15 m

Temporary earth-retaining wall

● The interlocks are situated on the outmost side of the section. This makes it unnecessary to consider the reduction of sectional properties which are factored in with U-type sheet piles. This leads to reduction of the number of struts.● The sheet piles can be re-used multiple times. (Refer to pages 13 and 14.)

Nippon Steel & Sumitomo Metal provides comprehensive solutions. We have a team of civil engineers at the head offi ce and the overseas offi ces. And we can propose the

optimum design plan by our products through discussions with our customer in a given time after we obtain

the design conditions. This is our complimentary engineering support to our customer. (Our proposal is for

reference of our customer. The responsible judgment is up to the customer.) (Refer to pages 11 and 12.)

Various types and sizes of sheet piles are available. The optimum type and size is selected based on the

design conditions and the construction method. (874cm3/m to 21,846cm3/m) (Refer to pages 7 and 8.)

● In the case of construction of a revetment at a seaside where a week layer exists, the improvement of soil is eliminated by embedding sheet piles into the load-bearing layer̶unlike a concrete caisson or stone revetment. This is an environmentally friendly method. (Refer to pages 17 and 18.)

Seawall

Steel sheet pile cell

The vertical load in the axial direction like a crane load is not applied. Welding can be carried out near the site.

NS-SP J pile and the dedicated press-in piler can construct a earth-

retaining wall without dead space. This enables the full use of the

premises to the boundary limits. (Refer to pages 25 and 26.)

● Superb drivabilityThe large sectional area of the Hat-type sheet pile

realizes superior drivability.

● High structural reliabilityNo reduction is required in sectional properties to

consider the possible lack of shear force transmission at

the interlocks, which is true for U-type steel sheet piles.

● Excellent cost-effectivenessThe amount of steel per unit wall can be reduced,

resulting in improved total cost.

The sectional properties of Hat-type sheet piles after 1 mm of corrosion loss per side, totaling 2 mm on both

sides, are shown in the table below.

Steps to calculate sectional properties after corrosion;① Assume the corrosion rate and lifetime of the facility,

and calculate the corrosion loss of the marine side t₁ (mm) and that of the land side t₂ (mm).

② Calculate the corrosion loss rate a (=t₂/t₁).③ Using the corrosion loss of the marine side t₁ (mm) and

the corrosion loss rate α , obtain the reduction ratio of the sectional properties η from the following graphs.

④ Calculate the sectional properties after corrosion loss, Z₀ and I₀, by multiplying the sectional properties before corrosion loss, Z₃, with I₀ by the reduction ratio η .

Section modulus Z ＝ Z₀×η Moment inertia I ＝ I₀×η

● Availability of numerous sectional propertiesHat-type and H-shape combined high stiffness steel sheet piles come in combination of Hat-type sheet piles which have two types and H-shape sections which have many types. Eventually they provide more than 200 types of economical properties. (Section modulus per meter of wall : Approx.2,120 to 19,940cm3/m)

● Ease of fabricationIt is easy to fabricate Hat-type and H-shape combined high stiffness steel sheet piles by combining Hat-type and H-shape with intermittent fi llet welding. Welding can be carried out at the site or the nearby yard or shop.

● Excellent cost-effectivenessFrom the viewpoint of design for the Hat-type and H-shape combined high stiffness steel sheet pile, Hat-type functions as a continuous wall to sustain soil and water, and H-shape functions as a structural member to bear the bending moment. This makes it possible to use low-cost H-shape up to 50 to 70% of weight as well as avoiding use of expensive connectors to connect a sheet pile and a section.

● Ease of InstallationAn ordinary vibratory hammer is directly applicable for driving. The Hat-type and H-shape combined high stiffness steel sheet pile, having higher moment of inertia per pile compared with Z-type and other type piles, is very easy to work with.

● Close-proximity installationNS-SP-J piles can be installed in close proximity to existing structures, permitting the construction of retaining walls abutting site boundaries and making maximum use of the site area.

● 100% intelock integrityAs interlocks are located on the outermost side of the way, there is no need to consider the reduction of sectional properties due to slip on interlocks, and this permits economical design.

● Cost-saving and Work-shortening of　 Temporary Work

Cost-saving and the shortening of temporary work timeCompared to conventional steel sheet piles for temporary work with an effective width of 400 mm, NS-SP-J has an effective width of 600 mm. This makes it possible to reduce the number of installed piles, with less cost and improved water tightness.

■ Sectional properties after corrosion

Io, Zo : Moment of inertia and section modulus without corrosion lossη : Reduction ratio after corrosion I, Z : Moment of inertia and section modulus after corrosion

Steps to calculate sectional properties after corrosion;① Assume the corrosion rate and lifetime of the facility, and calculate the

corrosion loss of the marine side t₁ (mm) and that of the land side t₂ (mm).

② Calculate the corrosion loss rate a ( ＝ t₂/t₁).③ Using the corrosion loss of the marine side t₁ (mm) and the corrosion

loss rate a, obtain the reduction ratio of the sectional properties η from the following graphs.

④ Calculate the sectional properties after corrosion loss, Z and I, by multiplying the sectional properties before corrosion loss, Z₀ and I₀, by the reduction ratio η .

Section modulus Z ＝ Z₀×η Moment inertia I ＝ I₀×η

● Corner sheet piles are a newly developed type produced by rolling, to replace the conventional T-shape corner-sheet piles produced by welding. Thus, these eliminate the need for welding and other fabrication processes and are far lighter in weight.

● For assembly, the conventional cast equipment can be used as-is.

● In particular, Larssen sheet piling has been adopted as a base for the shape of corner joints, in order to prevent detachment, and therefore, particularly, joint performance such as fi tment and repetition endurance is excellent.

Execution details: Tie rods, waling

Corner section: Hot-extruded shape steel

One of the methods for connecting a corner is the method of using hot-extruded shape steel, which is a

product formed using a hot-extrusion method and not necessarily involving welding at the site. As shown in

the fi gures below, this product is applicable for use at various angles.

To support a part of the external force applied to the steel sheet pile, sheet pile walls are often provided

with waling, tie rods, and tie wires at the upper part of the steel sheet pile. The following fi gures show an

installation example of a tie rod and waling.

Corner section: Irregular-shape steel sheet piles

Irregular-shape steel sheet piles are used for the change of the driving normal line of a steel sheet pile, for

the correction of the intersection point of steel sheet pile walls, or for the correction of the slope of the normal

line of a steel sheet pile wall. Irregular-shape steel sheet piles are manufactured by vertically cutting the web,

assembling them in the intended shape, and welding them.

Angle-correction steel sheet piles

An angle-correction sheet pile corrects the angle

when driving the sheet pile. This type of sheet pile is

produced by either of the following two construction

methods: a method that obliquely cuts two steel sheet

pile webs to be assembled; and a method that cuts

the center of the steel sheet pile web and assembles

it by inserting a trapezoidal steel plate into the center.

When using a trapezoidal steel plate, it is necessary

to use steel with a strength equivalent to or stronger

than that of the steel sheet pile base material.

Driving of a U-type sheet pileExecution details: Guide frames

Exection details : Concrete coping

In installation of steel sheet piles, it is necessary to install guide

frames to ensure correct driving position and the stability of the

steel sheet piles during construction. Here, one example is shown

in which two rows of guide frames parallel to the normal line are

driven at intervals of 2 to 4 m and in which the guide beam is

mounted inside.

To prevent water from entering the joint or to improve joint effi ciency of U-type steel sheet pile, it is usually

install the concrete coping at the top of steel sheet pile walls. Here, one example shown in below.

■ Vibration method

Driving method

Sheet piles are driven into

the ground by transferring

vibratory forces generated

by a vibratory hammer. As

percussion force is not used,

the pile head is not damaged,

driving effi ciency is high, and

it is useful for both driving

and pulling piles.

Sheet piles are pressed-in using hydraulic mechanism by grasping the middle place of sheet pile while taking

reaction by holding driven piles. Driving machine is compact, and need not crane, though it needs crane

separately for hanging sheet piles. It is applicable to the driving conditions such as narrow places and low

clearance places. It is also possible to drive piles in conditions of low noise and low vibration. When ground is

so hard that driving is diffi cult by using only pressing machine, it is useful to use water jet cutter together.

■ Percussion method

A percussion method is a method in which steel sheet piles are driven into the ground with the percussion

force of a hydraulic hammer or diesel hammer. To prevent buckling at the head of the sheet pile, a pile cap is

generally attached to the head of the sheet pile. Sheet piles can be easily built with high percussion force at a

location with large joint resistance or ground resistance.

(b) Hat-type sheet pile

(a) U-type sheet pile

When steel sheet piles are used, multiple sheet piles are sometimes joined to obtain a specifi ed length.

In general, a weld joint is used.

When welding, it's need to choice welding rod as considering base material, thickness of sheet pile, position

of weld. Here, shows the examples of welding material of JIS.

A steel sheet pile consists of continuous steel

material and is itself water-impermeable material.

However, considering the ease of driving, a slight

gap is provided at the joint.

It is known that, generally, the amount of water

leaking from the joint is reduced over time by

clogging sand.

However, if you would like to stop water at an

early stage, it is necessary to take measures to

stop water at the joint.

The most popular method is when swelling water-

stop material is preliminary applied to the joint.

Various water-stop materials have been developed

for this. For details, please contact us.

The following methods are available to prevent the corrosion of steel sheet piles.

(1) Designing the sheet pile considering corrosion allowance

(2) Cladding using concrete to prevent corrosion

(3) Coating the sheet pile to prevent corrosion

Four types are available with regard to this method: by painting; using organic lining: using petrolatum

lining; or using inorganic lining.

(4) Electrolytic protection method

Two types are available with regard to this method: by externally supplying a protection power source to

prevent corrosion (external power method) or by attaching alloy such as aluminum and magnesium to the

steel material as a sacrifi cial anode (galvanic anode method).

It is necessary to select the most-optimum corrosion prevention method according to the design and site

condition. For details, please contact us.
