Typically in the form of a horizontal wire or rod, or a helical anchor, a tieback is commonly used along with other retaining systems (e.g. soldier piles, sheet piles, secant and tangent walls) to provide additional stability to cantilevered retaining walls. [1]
A soldier pile wall using reclaimed railway sleepers as lagging. Soldier piles, also known as king piles or Berlin walls, are constructed of steel H sections spaced about 2 to 3 m apart and are driven or drilled prior to excavation. As the excavation proceeds, horizontal timber sheeting (lagging) is inserted behind the H pile flanges.
Larssen sheet piling is a kind of sheet piling retaining wall.Segments with indented profiles (troughs) interlock to form a wall with alternating indents and outdents. The troughs increase resistance to bending.
The Statnamic load test is a type of test for assessing the load-carrying capacity of deep foundations which is faster and less expensive than the static load test.The Statnamic test was conceived in 1985, with the first prototype tests carried out in 1988 through collaboration between Berminghammer Foundation Equipment of Canada and TNO Building Research of the Netherlands.
The Danish pile-driving formula is a formula which enables one to have a good gauge of the bearing capacity of a driven pile. History The formula was constructed by ...
Franki piles can be used as high-capacity deep foundation elements without the necessity of excavation or dewatering. [4] They are useful in conditions where a sufficient bearing soil can only be reached deeper in the ground, [5] [6] and are best suited to granular soil where bearing is primarily achieved from the densification of the soil around the base. [4]
It differs from the statnamic load test and dynamic load testing in that the pressure applied to the pile is slower. [1] [2] Static load testings are performed in order to measure a design's axial tension or axial compression. It can also be used to measure its deflected shape under lateral load.
The design parameters for the piles can be independently chosen from the Tripod itself and reflect the geotechnical needs explicitly. There is no need to apply scour protection. The connection to the pile is usually achieved using a grouted connection. This is a technique where special concrete is poured in the joint gap between pile and pile ...
