The piling industry has, in recent years, developed a variety of press-in piling technologies with a view to mitigate noise & vibration nuisance. This book focuses on the "Walk-on-Pile" type press-in piling system, which offers an alternative engineering solution for piling works. This type of piling has unique features, including the application of the compact piling machine using pre-installed piles as a source of reaction force to jack in a new pile by hydraulic pressure. Moreover, the machine can walk along the top of piles already installed, thus enabling piling in a limited space and headroom with minimum disruption to social functions and services of existing infrastructure. These features are opening up a new horizon in piling, leading to novel application of embedded walls previously considered impossible.This introductory book provides a historical development of press-in piling and various challenging applications worldwide as well as scientific research outcomes, forming a valuable source of reference for readers who are unfamiliar with press-in piling, including project owners, design engineers, practical engineers as well as researchers and students.

The Deep Mixing Method (DMM), a deep in-situ soil stabilization technique using cement and/or lime as a stabilizing agent, was developed in Japan and in the Nordic countries independently in the 1970s. Numerous research efforts have been made in these areas investigating properties of treated soil, behavior of DMM improved ground under static and dynamic conditions, design methods, and execution techniques.Due to its wide applicability and high improvement effect, the method has become increasingly popular in many countries in Europe, Asia and in the USA. In the past three to four decades, traditional mechanical mixing has been improved to meet changing needs. New types of the technology have also been developed in the last 10 years; e.g. the high pressure injection mixing method and the method that combines mechanical mixing and high pressure injection mixing technologies. The design procedures for the DM methods were standardized across several organizations in Japan and revised several times. Information on these rapid developments will benefit those researchers and practitioners who are involved in ground improvement throughout the world.The book presents the state of the art in Deep Mixing methods, and covers recent technologies, research activities and know-how in machinery, design, construction technology and quality control and assurance.The Deep Mixing Method is a useful reference tool for engineers and researchers involved in DMM technology everywhere, regardless of local soil conditions and variety in applications.
