Definitions

  • the invention relates to a method for infiltration of water in a trench and a drainage system with the trench.
  • trenches ie underground storage tanks for precipitation water
  • trench bodies can be modularly constructed with trench bodies of various shapes made of plastic and protected against seepage from outside by a geotextile shell.
  • inspection shafts into such trenches in order to permit inspections of the trench bodies by means of remote-controlled camera systems and / or internal scouring of the trench with high-pressure jets.
  • the lowermost trench bodies can be driven by small vehicles in a suitable manner. Such inspection and / or cleaning is required, for example, due to the entry of precipitation water sediments to maintain the performance of the trench.
  • this serves for the infiltration of water in a trench.
  • the water is fed underground drainage pipes. From these, the water exits through drainage openings distributed longitudinally along the drainage pipes and thereby distributes itself to at least one outer wall of the trench in this direction in all directions. As a result, the water thus distributed penetrates into the trench at least partially through a geotextile casing surrounding the trench.
  • An at least partial penetration of the water into the trench is understood to mean that water leaving the drainage pipes does not have to penetrate completely through the geotextile casing into the interior of the trench.
  • the drainage pipes are arranged exclusively outside the geotextile shell of the trench. Since there is no direct connection of drainage pipes to trench bodies inside the trench, infiltrated water enters the trench exclusively through the geotextile shell.
  • the water then flows out of the drainage openings preferably first through a gravel bed surrounding the drainage pipes and then, in particular through another geotextile casing surrounding the gravel bed, to the outer wall of the rigging, penetrates its geotextile shell and accumulates upwards, in particular in the trench.
  • the longitudinal distribution of the drainage holes causes a uniform distribution of the water to be seepage in the lateral direction along the outer wall of the trench and preferably along several outer walls of the trench.
  • Sediments entrained in the water preferably sediment in a lower sedimentation area of the drainage pipes, and the water exits from the drainage pipes above the sedimentation area.
  • the sediments are comparatively well accessible for inspection and / or cleaning in the sedimentation area.
  • the drainage pipes can be formed impermeable to water. The sedimentation is formed before stable so stable that it can be traveled by remote-controlled camera systems and is suitable for flushing by means of high-pressure jet.
  • the drainage pipes distribute the water in the circumferential direction along at least one outer wall of the trench, in particular fully.
  • the advantageous function of the method is already given with a water supply to a side wall of the trench.
  • the described water supply preferably takes place on several side walls of the trench. This allows the trench from several sides apply evenly to water to be infiltrated.
  • the water supply is practicable, for example, by means of drainage pipes laid on two or three side walls, and especially effective with complete laying of the drainage pipes.
  • an above-ground access to the drainage pipe is preferably produced via at least one inspection shaft.
  • the drainage pipe is then relatively easily accessible for inspection and / or cleaning.

Accordingly, this includes a subterranean and surrounded by a geotextile casing rigging and outside of the geotextile casing at the side of the trench along running drainage pipes for subterranean introduction of water to be seeped.

Abstract

L'invention concerne un procédé permettant de drainer de l'eau dans une rigole (2), ainsi qu'une installation de drainage correspondante. Selon l'invention, l'eau est acheminée jusqu'à des tuyaux de drainage (5) posés sous terre, l'eau sortant desdits tuyaux de drainage par des ouvertures de drainage (15) réparties le long de ceux-ci, l'eau se répartissant de ce fait sur au moins une paroi extérieure de la rigole (2) dans sa direction périphérique latérale et pénétrant ensuite au moins en partie dans la rigole (2) par une enveloppe en géotextile (4). On peut ainsi limiter des impuretés par sédimentation ou similaire sur la zone des tuyaux de drainage (5), de sorte à permettre que des travaux d'inspection et des travaux de nettoyage n'interviennent que pour les tuyaux de drainage (5) et de sorte à pouvoir éviter de manière fiable des détériorations de l'enveloppe en géotextile (4) de la rigole, liées aux travaux.
