Pile driving cushion pads, also known as pile driving energy dissipating pads, are an important component in the construction of foundations for buildings, bridges, and other structures. These pads are used to absorb the energy generated during the pile driving process, which involves driving piles, or long, slender columns, into the ground to provide support for a structure. Pile driving can be a noisy and vibration-intensive process, and the use of cushion pads helps to mitigate these impacts on the surrounding environment and nearby structures.
There are several different types of pile driving cushion pads, each with its own unique characteristics and benefits. Some common types of pads include elastomeric, rubber, and foam. Elastomeric pads are made from a rubber-like material and are designed to absorb energy through deformation, or stretching and compression. Rubber pads are made from a softer, more flexible material and are able to absorb energy through a combination of deformation and friction. Foam pads are made from a lightweight, spongy material and are able to absorb energy through deformation and compression.
In addition to absorbing energy, pile driving cushion pads also serve to reduce the amount of noise and vibration generated during the pile driving process. This is especially important in urban areas, where pile driving can disrupt the daily lives of nearby residents and businesses. By reducing noise and vibration, cushion pads help to minimize the negative impacts of pile driving on the surrounding community.
Pile driving cushion pads are easy to install and can be placed between the pile and the pile driver, or between the pile and the ground. They can also be used in combination with other noise and vibration reduction measures, such as noise barriers and vibration isolation systems.
Overall, pile driving cushion pads are an important tool in the construction of foundations for a wide range of structures. They help to absorb the energy generated during the pile driving process, reducing noise and vibration and minimizing the negative impacts on the surrounding environment and community.
Pile Driving Cushions
Hammer cushion pads have to be strong to withstand the pounding and to transmit the driving force needed while protecting your equipment and the pile. It is placed between the helmet and the pile. Square blocks can be provided with or without clipped corners. Our prices are competitive, and we pride ourselves on a quick and accurate turnaround. But it is a complex process that requires extensive testing and accurate calculation. For more information on our Redco Pile Driving Cushions. Pile cushion blocks are manufactured and constructed of plywood, hardwood, or plastic They are either Square or circular and the most common pile cushion blocks are constructed of multiple layers of plywood that have been nailed together to meet required thickness.
Pile Driving Basics, Common Problems, and Solutions
This product serves as the cushion between the pile driving hammer and the helmet, transmitting the maximum striking force to the pile. They are commonly used with Features At a great price point, aluminum is ideal for dissipating the extreme heat generated during the driving process. Drive Pile Blow Count Issues Blow counts are calculated in advance. If the observed blow count is less than calculated, soil resistance is likely lower than originally estimated. The outside diameter is made to fit the drive cap and the wall thickness is determined by the wall thickness of the cylinder pile itself. An engineer will need to evaluate the soil and determine next steps.
Keep in mind that driving the piles alters how the soil around it will behave. If you are not able to do an internal inspection you will need to evaluate the problem using dynamic measurements. Why would you not try to source these from a local supplier? All cushions are palletized and shrink wrapped for shipping and short term on site storage. Pile driving is a critical part of the construction process. APS can help protect both with our new Hammer Cushion Pads. Damage to the contact point of the pile is also lessened often making it unnecessary to trim the pile which can be a time consuming and costly procedure. Hammer Cushion A hammer cushion, typically made of man-made materials, is placed between the striker plate and helmet.
Lateral Movement in Previous Driven Piles If previously installed piles move laterally when new piles are driven, soil displacement is the likely culprit. One cause for damage near the head of a concrete pile is insufficient pile cushioning. A crane or excavator lifts the hammer. In the pile driving industry, hammer cushions are essential to reduce wear and stress and extend the life of your hammer. By absorbing this initial hammer shock, APS Cushion Pads reduce the tremendous wear and stress hammers are subjected to, thereby, minimizing breakdowns and nonproductive downtimes. Pile Foundation Design The design of a pile foundation is highly dependent on the soil the piles are driven into.
They are categorized by how they attach to the pile driver — hanging, fixed, or swinging. Each layer is nailed to form a fixed unit. The material can also be used in vibration dampening applications, mechanical stops or other high impact situations. Vertical columns made of various materials wood, concrete, steel, or a combination are driven into un-excavated soil. Hammer Issues Sometimes the pile driving hammer is the cause of problems.
The energy required to drive a pile was created by the weight of the ram falling through the gravity field. Early Pile Driving Early pile driving was done by hand. Reduce the hammer stroke for low blow counts; increase for high blow counts. The piles are a type of deep foundation used to hold up large structures — often bridges. Piles - heavy beams of concrete, steel, or other materials are pounded into the ground by a large "hammer" attached to a crane. This type of hammer greatly increased the speed with which piles could be driven.
APS manufactures each cushion pad to your specifications with accurate sizing guaranteed. They are powered by hydraulic motors. This provides greater accuracy as compared to standard monitoring. Leads keep the piling and hammer aligned. If you need an over- or undersized item, note it under "Comments" during Checkout.
PROTECT YOUR EQUIPMENT WITHOUT SACRIFICING POWER OR YOUR PROFITS In pile driving, the very nature of the business is pounding, but preferably not on your equipment or your profits. APS has the ability to cut pads to your specifications. Note that cracks discovered early may be repaired with epoxy. Warning: This product may have sharp edges and points. Here are common issues and solutions related to blow count: Increased Blows Needed to Drive Pile The number of blows needed to drive the pile to the required depth is calculated in advance. They must also protect your equipment and the pile.
These pads are often sold through distributors who have to markup pads that have high costs in price, shipping and inventory. Other causes may be a spliced pile, an obstruction, or the toe contact is uneven. Evaluate hammer performance and make adjustments, if needed. Hydraulic vibro hammer View the complete article here. Pile driving jobs are always on tight schedules with no time figured in for breakdowns or unnecessary pile trimming. Solutions can be included in contingency planning — avoiding cost overruns.
