A Brief History of Jet Grouting in the Last 50 Years: The Story of Its Evolution
Jet grouting, a grouting soil improvement construction technique, was first developed in Japan in the 1960s and 1970s, and then introduced in Europe a few years later in the form of a proposal for soil...
The New Bedford Marine Commerce Terminal
When construction of the first American offshore wind farm support terminal encountered greater challenges than expected, jet grouting enabled construction to continue....
Challenges and Risks of Jet Grouting in a Congested Urban Environment
In the heart of London, one of Europe's largest jet grouting contracts is nearing completion. The jet grouting is part of the overall 7-year-long upgrade project to London...
Sinkhole Investigation and Grouting: Novel Recommendations for a Pipeline Right-of-Way
In 2009, numerous sinkholes developed within and adjacent to a 400-ft-long section of high-pressure, petroleum pipeline right-of-way that crosses under a local creek in Plymouth Meeting,...
Grouting Methods
This chapter discusses common grouting methods used in underground applications in both soil and rock. Jet, compaction, permeation, and hydrofracture grouting methods are frequently used...
Geotechnical Considerations in Grouting Program Planning
This chapter explores geotechnical considerations in grouting program planning. Topics include: basic considerations; geotechnical investigation and geotechnical design summary; grouting...
Equipment
This chapter examines the types and sizes of equipment required to drill grout holes, proportion and mix grout materials, and deliver and inject grout into the holes in an underground...
Grouting Materials
This chapter explores the materials used for underground grouting. The basic materials used to produce grouts for underground use are the same as those used in aboveground applications....
Grout Hole Layout
The drilling method, either rotary or percussion, and the type and size of the drills to be used are selected based on such factors as rock type, depth of holes required, working space...
Grout Placement Operations
This chapter discusses grout placement operations. The procedures for drilling, proportioning and mixing, and injection used in underground grouting are basically the same as those employed...
Field Quality Control
A good quality control program helps ensure that technical requirements of the grouting are met and also adds to the overall success of a grouting project. The quality control program...
Chemical Grouting
Chemical grouting is used in underground construction primarily on soft-ground shafts and tunnels in an effort to control cohesionless or running ground conditions by modifying the soil....
