摘要

The method is for producing a vertical wall or column in the ground and involves the formation of a vertical groove filled with water, bentonite and possibly cement in order to stabilise the wall during the digging of the groove. A prefabricated component is placed in the groove so that its underside is free from the base of the groove and is immersed in the mixture. The mixture is then allowed to harden and the component is subjected to a vertical load, such as a weight, to hold it at a distance from the base of the groove. After the hardening, the component is uncoupled from the weight.
