Pile Hammer Size / Driving Criteria

 · Once you found the pile in dense sand 70 feet deep, you should be able to develop the 20 ton capacity easily. I would do a static analysis to check the pile capacity. The hammer was probably selected because it has a good sized ram so it can follow the pile through the organics and soft soils.

Pile Driving Installation Methods

There are three driving systems that are applicable to both retaining and bearing piles: impact driving; vibrodriving; pressing . Impact driving . The most common form of impact driving is the drop hammer, which uses a falling weight to create the impact, spread to the top of the pile by a driving cap.

How deep can a pile be driven?

 · Usual depths for concrete precast piles range from a few meters to around 30 m, but under special circumstances piles have been driven down to 150 m! Steel circular piles in offshore works can go much deeper. Offshore ultra-deepwater projects are somtehing else… Take a look at the following video, which explains how to install piles in deep.

PILE DRIVING INSPECTION MANUAL

Pile driving is unique in the construction industry, in that the machinery used to install the product is a vital part of inspecting and verifying the installation.

PILE LOAD CAPACITY

sented as well as the pile capacity problem based on static tests. Key words: pile load capacity calculation, Eurocode 7, α - method and β - method, direct methods based on CPTu data 1. INTRODUCTION Piles can be either driven or cast in place. Pile driving is achieved by: impact dynamic forces from hydraulic and diesel hammers; vibration.

Common Pile Driving Problems and Solutions

Choosing the correct pile foundation, and installing it in an optimum way, is crucial. We are dedicated to helping you achieve these goals. Our combination of expertise and innovative equipment allows you to construct every type of foundation pile: concrete or steel; precast or cast in situ; and drilled or driven.

Deep Foundations

 · The load bearing capacity of a pile depends on soil and structural capacity of the material from which the pile was made. Pile foundations also provide a reinforcement against seismic activity and wind forces. Pile Driving and Pile Composition. Pile driving is a method of deep foundation application.

Our combination of expertise and innovative equipment allows you to construct every type of foundation pile: concrete or steel; precast or cast in situ; and drilled or driven.

CHAPTER 3 PILE

FM 5-134 lead may be reduced to 55 or 47 feet by leavinghandles the hammer and pile lines. The leads out sections. The length of the lead is to the skid-mounted pile driver can be tilted.

INSTALLATION SPECIFICATION FOR DRIVEN PILES

The ultimate pile capacity can also be used in LRFD. Driven pile lengths are estimated for bidding purposes from soil investigation, static analysis, and perhaps local experience. However, rarely are these estimated lengths used to control production pile installations. Usually dynamic methods (e.g. dynamic testing, wave equation, or.

How to Drive Steel Sheet Piles APE Pile Driving School

•Strong interlock for hard driving •Can be made with thick (up to ¾ inch) wall for super hard driving •Web layout superior to cold formed (for hammer energy transfer) •More elastic at angle area (cold forming process reduces elasticity) •Excellent for reuse due to ….

How Using the Pile Driving Analyzer® (PDA) Can Benefit

PDA helps monitor driving stresses, helps reduce the risk of pile damage, and provides capacity of the pile in real time. If stresses indicate a high potential for pile damage, driving can be stopped and our Geotechnical Engineers can determine alternative installation procedures to ensure foundations and structures are being designed safely.

Pile Driving Analyzer

The Pile Driving Analyzer® (PDA) system is the most widely employed system for Dynamic Load Testing and Pile Driving Monitoring in the world. The PDA eighth generation (PDA-8G) acquires data from accelerometers and strain transducers attached to a pile or shaft so that High Strain Dynamic Tests (ASTM D) may be performed. The tests require.

 · from Pile and Sheet Pile Driving Part 1 - Building Damage." Here the authors focus on building damage that can be attributed to foundation conditions. In the case of ground vibrations due to pile and sheet pile driving, differential settlements are of particular importance as the ground vibrations attenuate relatively rapidly from the source.

The Different Types of Deep Foundations

Large hammers provide a high amount of energy that can quickly advance a pile and reduce driving time. However, heavy hammers require heavy loads and cranes, leading to decreased mobility and higher equipment costs. Large hammers also deliver more energy to the pile, which can result in pile damage and pile stress.

5.3 DRIVEN PILE

With all the hammer information known, use the appropriate dynamic pile driving equation to compute the blow count (average) for the specified driving load and 110% of this value. The value for over driving the pile was 150% when Allowable Stress Design was used to determine the soil and pile ….
