TABLE OF CONTENTS The shoring industry is rife with inventors who develop equipment to deal with special situations, and it simply would not be possible to show all of the equipment involved. However, the following chapter will attempt to outline some of the equipment used for the installation and prosecution of shoring.
Sheet piling is driven by either vibratory or impact hammers. In some cases, the sheet is installed to refusal with a vibratory hammer and then finished off with an impact hammer. Vibratory hammers (Figure 13.1) are usually hung from conventional crawler cranes. Alternatively, sheeting is driven by vibratory methods with a sheeting driver which mounts a vibrating head on a fixed lead (Figure 13.2). This configuration permits crowd or pull down to be exerted together with vibration. Sheet piles can also be driven by lead mounted diesel or air hammers.
Included in this category are soldier piles, secant piles, cylinder piles and tangent piles. These piles are installed by drilling a hole and placing a steel section within the hole and then backfilling the hole with structural and/or lean mix concrete. Holes can be drilled with truck mounted drill rigs (Figure 13.3), crane mounted drill rigs (Figure 13.4), or crawler mounted drill rigs (Figures 13.5...
