Method to manufacture foundation element; involves supporting guide unit in upper are of excavated space and inserting self-hardening suspension, which acts as support suspension below guide unit

摘要

The method involves supporting a guide unit (4) in the upper area (3) of an excavated space (2), leaving the remaining part (5) without a guide unit. A self-hardening suspension is inserted (6), which acts a support suspension in the area of the excavated space under the guide unit and forms the foundation element after hardening. The guide unit may be arranged so that it projects a small distance (a) above the ground surface (7).
