TRENCHING APPARATUS AND METHODS OF FORMING INGROUND RETAINING WALLS |
摘要 |
Trenching apparatus (10) for excavating deep trenches in which inground concrete retaining or foundation walls may be formed. The trenching apparatus (10) has a crawler base (11) on which a carrier assembly (14) is pivotally supported by pivots (16) whereby it may be tilted by rams (17) to maintain the platform horizontal. Automatic control means (64) are provided for this purpose. The carrier assembly (14) has a pair of rails (18/19) along which a carriage (21) may move. The carriage (21) supports a sleeve (24) through which a trenching arm (25) may be lowered to excavate a trench section as the carriage (21) is driven along the rails (18/19). |
