Layered placing of upright or sloping dam cores

摘要

EP--59515 A The upright or sloping dam cores of bitumen and/or plastics and/or a natural binder are placed in a constant or upward-tapering thickness. The core material is placed from a silo (2) on a travelling machine. Transitional material is at the same time placed against the core material from the machine silos (5). - The dam core is formed with the aid of a sliding formwork, which gives lateral support while the transitional material is placed. The core material is pre-compacted (4) vertically and laterally before the transitional material is placed. Subsequently both core and transitional material are further compacted (9).

(13pp Dwg.No.1/3) - EP--59515 B Machine suitable for the layered placing of upright or sloping dam cores of materials bound with bitumen and/or plastic and/or natural binder, in a constant or upward-tapering thickness for dams such as barrage dams, and of adjacent transitional material, comprising a) a sliding formwork to form the dam core, and containing compacting elements (4) for precompaction of the dam core, b) travelling elements (10) to move the machine while placing the dam, characterised in that it moreover comprises: c) a silo (2) from which the core material is placed in the sliding formwork, d) one or more silos (5) from which the transitional material is placed alongside and against theplaced core material, e) vibrating plates (4), which are located on or in the sliding formwork, for pre-compaction of the core material both vertically and laterally immediately after it has been placed and before the transitional material is placed, f) vibrating plates (9), which are located at the rear of the machine, for further compaction of the core material and the simultaneous comapcting of the transitional material, the sliding formwork still protecting the formed core until and while the placing of the transitional material from the silo(s) (5). (7pp) USAB- US4508471 A The method is for the layered placing of upright or sloping dam cores of material bound with bitumen and/or plastic and/or a natural binder in a constant or upward-tapering thickness for dams such as barrage dams. The core material is placed from a silo of a travelling machine and at the same time transitional material is placed, from one or more silos of that machine, alongside and against the placed core material. - The dam core is formed with the aid of a sliding formwork located on the machine to give lateral support to the core until while the transitional material is placed. The core material, immediately after it has been placed and before the transitional material is placed, is pre-compacted both vertically and laterally. Subsequently the core material and the transitional material are (further) compacted. (5pp)i
