Because of the large deflections that may develop, cantilever sheet pile retaining walls are mainly used for temporary excavations not greater than about 18 feet. However, the use of struts and/or walers can increase the wall height.
Cantilever sheet piles
These are usually used for heights of 6m or less.
you don't plan to sit on your wall, 3 feet is about as high as I would recommend building any dry-stacked wall; higher walls should be engineered for stability.
As general rule of thumb it can be assumed that: “the recommended sheet pile length in [cm] corresponds to the section modulus in [cm3/m]”. However, soil conditions have to be checked carefully. > 1840 cm3/m section modulus; > Recommended length max. 15-18 m for soil condition “Easy”.
It is the most common type of retaining wall and its height ranges up to 10-25 feet (3 to 8m). Counterfort retaining walls are economical for height over about 6 m. A cantilever retaining wall resists the earth pressure horizontal & another, by the cantilever bending action.
A brick wall normally go up to 2.6 - 3 m (8.7 - 10 ft) without reinforcement.
7 Factors to Consider When Determining How High a Brick Wall Can Be Built. As a general rule of thumb, expect to build a single brick wall up to 7 feet before putting in extra support systems.
Combined sheet piling wall beam and pipe king piles are able to go deeper into dense soils than sheet piling sections of a contiguous wall — approximately 6.5 feet (2 meters) compared to 1.5 feet (0.5 meters).
The primary difference between soldier piles and other retaining systems like sheet piles is that soldier piles are spaced between 5 and 10 feet apart and intended to be temporary. They're filled with lagging, usually made of shotcrete, metal plates, or wood.
Excavation: sheet piles can also be excavated into the soil. A long trench is excavated which is then filled with cement bentonite (a thin concrete slurry) to prevent the walls from collapsing. The sheet piles are then installed in the trench and the cement bentonite is allowed to set.
Lumber shall be so stacked as to be stable and self-supporting. Lumber piles shall not exceed 20 feet in height provided that lumber to be handled manually shall not be stacked more than 16 feet high.
Minimalist running shoes (minimal stack height: 3-13mm) Regular running shoes (medium stack height: 9-35mm) Maximalist running shoes (maximal stack height: 35-50mm).
Stacks shall not be piled so high as to make them unstable under fire fighting conditions and in general they shall not be more than 4.5 m in height.
It depends on usage: low-pile (under 0.5 inches) is durable and easy to clean, while high-pile (over 0.5 inches) is plush and ideal for cozy spaces.
The most common methods of installing steel sheet pile walls include vibrating, impact driving, hydraulic pushing, jetting, and trenching.
The economical height of this type of wall is generally limited to a maximum height of 18 feet. Figure 6-2 shows a typical soldier pile retaining wall.
Typically, a sheet pile retaining wall, described in this way, would be used for earth or inland water retention. In a marine environment, it is probably more commonly described as a quay or harbour wall. In bridge construction, it is often called a bridge abutment.
When you need a cofferdam for water construction, TrapBags are an ideal alternative to sheet piling. TrapBags are more cost-effective and versatile, giving you the water control barrier you need.
The weight of the pile vs the hammer weight – a good rule of thumb is that the hammer is 50% heavier than the pile to be driven. Excessive hammer size in relation to the pile weight and gauge will significantly increase the risk of pile damage.
For situations where limited deterioration rate is applicable and/or economic protective measures can be employed, design lives in excess of 125 years can regularly be achieved.
Use an adequate template
The utilization of an adequate steel template will facilitate the installation process and result in a superior end product. The purpose of the template is to both properly align the sheets during the setting process as well as to keep the sheets in alignment during the driving phase.
Typically, in residential construction, the standard wall height is 8 feet (or approximately 2.4 meters).
In general, 2 x 4 wall framing is structurally sufficient for many small garages and sheds. When bearing wall heights do not exceed 10 ft. 2 x 4 framing is generally code compliant.
Cantilever retaining wall:
It is the most common type of retaining wall and its height ranges up to 10-25 feet (3 to 8m). Counterfort retaining walls are economical for height over about 6 m.
