Press-in Method (Piling technology) with “Silent Piler”


Press-in Technology (Eco- friendly Piling Works), Construction Revolution and Disaster Recovery Technology

【Silent Piler and Press-in Method】


iken manufactures a piling machine called Silent Piler™ and offers various construction technologies with the Press-in Method, to worldwide. The Silent Piler™ characteristics, including but not limited to, low noise, no vibration, and compactness, which allow to work in constrained areas, such as overwater, restricted headroom, and construction sites along existing buildings.
One of the representative Press-in Methods, Non-Staging Method, provides benefit to the total construction work as it allows the installation of piles without a temporary stage, and hence reduces the construction cost and period.

【Press-in Principle】
The Silent Piler grips the previously installed piles with the hydraulically operated Clamps. The next pile is then gripped by the Chuck at the press-in point and jacked into the ground with the static load generated by the hydraulic rams.
During the jacking, penetration resistance comprising of skin friction, toe resistance and interlock resistance occurs. It has the effect to convert a press-in force to a reactive lifting force but it is a greater force, provided by the extraction resistance of the reaction piles that resist this. Consequently, the down-stroke force acts on the pile to penetrate the ground.

Major Features and Advantages

  1. Press-in Method will not generate environmental pollution from construction such as noise and vibration.
  2. Silent Piler is so light and compact that its extent of the piling activities can be minimised.
  3. Pre-fabricated piles produced at the plant are pressed in directly, so high-quality completed piles can be built with peace of mind.
  4. Multiple sets of compact machines and apparatuses can be used at the same time to greatly shorten the construction period.
  5. Speedy piling progress is available, because there are least limits in working hours even at highly restricted areas and night works.
  6. All machines are so compact that it is not necessary completely close active traffics.
  7. The performance of piles can be checked and controlled during the construction, allowing high-quality completed piles to be built

Competitive advantage

  1. Press-in Method won’t generate environmental pollution such as noise and vibration.
  2. Non-Staging Method can solve some construction problems.
    ・No Temporary Structures are Required.
    ・It can work in Tight Conditions where Conventional Methods are Difficult.
    ・Respectful of the Surrounding Area.
    ・Excellent Safety with No Risk of Overturning.
  1. Construction of structural wall under headroom restriction site is possible without impacting the surrounding environment, i.e. Traffic by using Overhead Clearance Method.
  2. Installation of piles by Press-in Method achieves high rigidity and retainability.
