A steel sheet pile being hydraulically pressed. Hydraulic press-in equipment installs piles using hydraulic rams to press piles into the ground. This system is preferred where vibration is a concern. There are press attachments that can adapt to conventional pile driving rigs to press 2 pairs of sheet piles simultaneously.
Movax is a developer and manufacturer of excavator-mounted, automatically controlled piling and foundation equipment and the inventor of the patented modular side grip technology. [1] The product range includes a selection of excavator-mounted accessories like side grip vibratory pile drivers ( SG ), impact-type piling hammers ( DH ), piling ...
The model mathematically represents the pile driving hammer and all its accessories (ram, cap, and cap block), as well as the pile, as a series of lumped masses and springs in a one-dimensional analysis. The soil response for each pile segment is modeled as viscoelastic-plastic. The method was first developed in the 1950s by E.A. Smith of the ...
Sheet piling is a form of driven piling using thin interlocking sheets of steel to obtain a continuous barrier in the ground. The main application of sheet piles is in retaining walls and cofferdams erected to enable permanent works to proceed. Normally, vibrating hammer, t-crane and crawle drilling are used to establish sheet piles. [citation ...
The new HHK-S hydraulic hammer range was launched in 2001. A new drilling rig platform was launched in 2005. Junttan became a part of the PiloMac group in 2006. Launching Junttan's biggest hydraulic hammer, the HHK 25S, in 2007. Manufacturing the 1000th Hydraulic hammer in 2007. Manufacturing the 500th Piling rig in 2008.
The drill pipes transmit the necessary feed force and rotation to the hammer and the bit, along with the fluid (air, water or drilling mud) used to actuate the hammer and flush the cuttings. The drill pipes are added to the drill string successively behind the hammer as the hole gets deeper. The hammer is fully fluid actuated.
Q dy = ultimate dynamic bearing capacity of driven pile; α = pile driving hammer efficiency; W H = weight of hammer; H = hammer drop; S = inelastic set of piles, in distance pr. hammer blow; S e = elastic set of piles, in distance pr. hammer blow; L = pile length; A = pile end area; E = modulus of elasticity of pile material
This is an engineering term for describing how far to drive piles. [1] It is also used in surveying when driving metal posts and monuments that are to be used as bench marks (ie. the elevation of which will be established to a high degree of accuracy). When a very high degree of stability is required the post will be inside an oil filled outer ...
