    摘要： A method and apparatus are disclosed for preventing excavation damage to buried infrastructure. A plurality of excavation-sensing modules is buried near the buried infrastructure. The buried infrastructure excavation-sensing modules protect and detect buried infrastructure by emitting dense clouds of visible gas when the excavation-sensing modules are activated by impact with excavation equipment. In most instances, the visible gas will be brightly colored and it may also have a strong odor. In addition to the gas released by the modules, a loud sound may also be produced by the activated excavation-sensing module. This alerts construction crews or other workers that their excavation is nearing a protected underground structure. Once installed, no maintenance or active monitoring is required.

    摘要： The invention concerns a device comprising a linear conductive element arranged proximate to the work to be detected and monitored, associated with a connection system including housings connecting several sections of a conductor and end-of-line housings, whereof at least some comprise a connection point for a detection signal generator and at least a switch enabling to insulate the conductor section wherein the signal is to be injected. A housing (2) provided with a connection point for a detection signal generator comprises a normally closed contact consisting of two conductive components (8, 9) which, arranged on the line whereof the continuity is to be ensured, are mutually pressed when no action is exerted on them, the connection point comprising means for inserting and guiding a plug which, connected to the detection signal generator, is designed when it is engaged in the housing to be supported on the component (8) connected to the line section wherein the signal is to be injected while spacing it apart from the other component (9).

    摘要： The invention relates to a covering and marking device for an underground standpipe. The invention regards a covering and marking device of a vertical standpipe mounted on a sewage pipe situated underground, the covering device being designed such that it also serves as marking for the highest point of the vertical standpipe, it being the object that during carrying out mechanic excavation operations the standpipe can be more quickly localised and damage to the standpipe and the sewage system is prevented.
