Chapter 1Introduction

The purpose of this document is to provide practical guidelines for the construction of the Combi-GyroWall.
The intended audience for this document is engineers and construction specialists involved in the design,construction, and contracting of foundation elements for infrastructures.
The press-in piling method is commonly used worldwide because of its very quiet operation, ultra lowvibration, and flexibility of sizes to suit different wall properties and subsoil conditions.
The main attributes of the Combi-Gyro Wall are efficiency of physical wall properties and reusability. The
Combi-Gyro Wall comprises steel tubular piles as the primary element and steel sheet piles as thesecondary element. The efficiencies of physical wall properties can be optimised in view of the flexibilityof pile size and the spacing of tubular piles for the ground conditions and the form of the loading. The
Combi-Gyro Wall is installed by the press-in method and pile penetration force is monitored andrecorded throughout the piling operation. This thorough monitoring and recording system alleviates
concerns of quality control, as well as providing a comprehensive quality control method for a
performance-based contracting process.
This document provides a description of construction equipment and procedures of the Combi-Gyro
Wall.
