SYSTEMS AND METHODS FOR INSERTING SUPPORT MEMBERS INTO THE GROUND

Support members for heliostats (or other components installed in a field) can be hollow and thin-walled, for example, to reduce construction and/or material costs. However, such support members may be relatively fragile and susceptible to buckling or other damage when driven into relatively rocky and/or hard-packed soil using pile-driving. To avoid damaging the support members, the soil may be pre-conditioned to loosen the soil prior to insertion of the support member therein. An auger can drill a hole in the soil and then be reversed such that soil remains in and/or is subsequently re-introduced into the hole after removal of the auger, thereby leaving a substantially loosened column of soil in the hole. Vibration hammering can cause temporary liquefaction of the soil around the support member to insert the support member into the column of soil while reducing the potential for damage to the support member. 112-.

Drill for setting support member in soil

A method and an apparatus for producing a support element in the ground are described, a hole being sunk through non-stable ground at least down to the load bearing soil. As a result of a wedge-shaped construction of the drill bit the loosened soil is displaced into the adjacent region of the hole and consequently the area round the hole is compacted. The drill has a circular cylindrical core, which is provided with an outlet opening in the vicinity of the drill bit. Preferably tampable material is filled through the core tube, accompanied by the retraction of the drill. The material is simultaneously tamped with the aid of the drill. The invention has the particular advantage that, in cost effective manner, it is possible to use tampable material from the area immediately surrounding the building site and there is no need for expensive, classified filling material.
