Abstract

The equipment is particularly for working underwater, the sampling tube being accommodated in a pipe for driving into the earth. The sampling tube guide (2) is combined into a transportable unit with a base (3, 4 6-8) at right angles to it. Inside the guide above the sampling pipe (1) driving head is a hammer block mounted on a compressed-air driving ram forming part of a striking mechanism (11) equipped with a return-stroke catch (12). Means are included for attaching a hoist rope (13), also one or more air hoses to the ram cylinder (14). The closed ram housing can extend past the hammer block to an anvil resting on the top of the sampling pipe, being joined to the anvil by a watertight elastic bellows.
