Sprout
The sprout (also bracing ) describes the stiffening of a shoring wall in the trench and is derived from the word rung . It used to be used hardwood beams of oak or beech , but today are primarily Sprießungen of steel in use.
The shoring wall consists of two steel walls and several sprouts that stiffen the steel walls. Together these parts form a unit. Without the sprouting, it would not be possible to build in a retaining wall, as the earth pressure would quickly cause the trench to collapse. Only in the case of very stable soils and shallow trench depths can a retaining wall with sprouting be dispensed with. The construction trade association therefore stipulates that a trench from a depth of 1.25 m may not be carried out without wall protection. Nevertheless, tragic accidents occur again and again because this regulation is not observed.
