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 ...
Vibratory pile hammers contain a system of counter-rotating eccentric weights, powered by hydraulic motors, and designed so that horizontal vibrations cancel out, while vertical vibrations are transmitted into the pile. The pile driving machine positioned over the pile with an excavator or crane, and is fastened to the pile by a clamp and/or ...
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 ...
A heavily damaged piling structure can be reinforced by cutting out the damaged section and replacing it with preservative-treated wood. [14] Wrapping piles with plastic barriers can provide protection from marine borers for 25 years or more. [14] Pile reinforcement with concrete can be sufficient by filling the void with coarse stone and ...
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 Raymond Pile Driving Company. Wave equation analysis of piles has seen many improvements since the 1950s such as including a thermodynamic diesel hammer model and residual stress. Commercial software ...
Hydraulic hammer may refer to: Breaker (hydraulic) , a powerful percussion hammer fitted to an excavator for demolishing hard structures Hydraulic hammer, a type of piling hammer
Larssen sheet piling was developed in 1906 by Tryggve Larssen, engineer from Bremen (Germany). [ 2 ] [ 3 ] [ 4 ] Its applications include piers , oil terminals , waste storage facilities, shoreline protection, [ 5 ] bridges, houses, buildings, dry docks, other construction sites, and for the strengthening of pond banks, preventing slumping into ...
Vibratory Stress Relief, often abbreviated VSR, is a non-thermal stress relief method used by the metal working industry to enhance the dimensional stability and mechanical integrity of castings, forgings, and welded components, chiefly for two categories of these metal workpieces:
