摘要
Provision is made for installing flexible tubes in a vertical assembly for solar energy collectors in the ground. The pile-driving rods, with lost contact tip, are made in two, or pref. three parts. They have a ramming shaft with guiding devices for flexible tubes or other objects to be inserted in the ground, and a ramming tip, guided by the shaft, with holders for these objects. A rammer hood has attachments for tensionally rigid connection with shaft. The shaft may be hollow, and have external guiding grooves. This enables the usual horizontal pipes to be also used in a vertical position, with less earthworking involved.
