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...

Working Platforms for Specialty Geo-Construction
A major cause of rigs toppling over is the state of the "working platform" that they must work from. A working platform is a layer of material, often compacted sand or gravel, placed over the subgrade,...

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....

Dynamic Shearing Properties Of Compacted Clay
A series of 116 Q-type triaxial compression tests was performed using specimens of Goose Lake clay compacted at water contents ranging from 9 percent dry of optimum to 3 percent on the...

Effective Stress Theory of Soil Compaction
The shape of the moisture-density curve obtained from compaction tests has been explained in terms of capillarity and lubrication, viscous water, and physico-chemical interactions. None...

Pore Water Pressures in Unsaturated Soils
Unsaturated soils are three-phase systems composed of solid mineral matter, water, and air. Such soils may be formed by either natural or artificial means. Except in moist environments,...

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,...

Development and Field Testing of a Pressure-Sensing Grout Packer

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...

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...

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...

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....

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 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...
