摘要
An apparatus (10) for forming a drainage assembly (50) within and along an elongate trench (58), the trench (58) generally having a base wall (59) and side walls (57), the drainage assembly (10) comprising an elongate conduit (30) extending along the trench (58) and substantially surrounded by an aggregate material (20), the apparatus (10) comprising a conduit guide means (78) adapted to dispose a length portion of the elongate conduit (30) within the trench (58), and an aggregate material delivery means (120) adapted to distribute aggregate material (20) within the trench (58) such that the length portion of the elongate conduit (30) within the trench (58) is substantially surrounded by the aggregate material (20), wherein movement of the apparatus (10) along the trench (58) in use disposes subsequent length portions of the elongate conduit (30) and further aggregate material (20) within and along the trench (58) to form the drainage assembly (50). In the preferred embodiment, the drainage assembly (50) further comprises an elongate flexible membrane (40) surrounding the aggregate material (20) within the trench (58), and the apparatus (10) further comprises a membrane guide (151, 70, 142) adapted for configuring a length portion of the elongate flexible membrane (40) into a channel configuration within the trench (58) in use.
