A soil treatment apparatus ( 100 ) comprises a ring ( 114 ) having a first ring part ( 128 ) and a second ring part ( 128 ). An elastomeric clamping arrangement ( 116 ) comprising rubber annular parts ( 116 ) and end flanges ( 112 ) clamp the first and second ring parts ( 128 ) together to form the ring ( 114 ) and provide an axial compressive force on the parts. In another aspect, the ring is carried on the elastomeric clamping arrangement ( 116 ) to absorb shock loading on the ring.
