Figure 10.21 Types of anchorage body: (a) frictional resistance type, (b) bearing resistance type, and
Anchorage bodies can be formed througli direct pouting without pressure, low grouting pressure (the grouting pressure lower than 10 kg/cm2 ), high grouting pressure ( the grouting pressure greater than 20 kg/cm2 ) and underreaming, as shown in Figure 10.22.
