Site investigation specialist Lankelma is using its UK12 dedicated cone penetration testing rail truck on Network Rail’s Cardiff area signal renewal works.
The tests, classified as spiking tests by Network Rail, are designed to ascertain the strength of the underlying ground.
So far 61 exploratory holes have been completed in 12, five-hour night shifts. A further 12 night shifts are planned for the work around the Cardiff to Newport area and at Caldicott.
The UK12 rail truck - the only one of its type in the world, according to Lankelma − was designed to improve productivity in soil investigation in the rail environment. A test to a depth of 15m can be accomplished in about 40 minutes, and several tests can be undertaken in a single possession.
Site personnel can be carried in the cabin, which reduces movement time between locations.
