  • the deflector comprises a base 410 having affixed thereto a plurality of curved upper resilient members 411.
  • the resilient members 411 are attached in end-to-end configuration upon the base 410 and are secured thereto by means of a pair of lengthwise strips 413, each having apertures therethrough through which bolts pass to secure the assembly together.
  • the deflector may be placed at the base of a silt fence 414 for example.
  • Each of the curved upper members 411 comprises a plurality of apertures 412 in the side facing the expected flow of water. That is, water which would otherwise pass the deflector can enter into the space between the upper members and base 410 via apertures 412. Water may then flow longitudinally of the deflector through the internal hollow as indicated. Further apertures may be provided along the metallic strips 413 for the purpose of staking the deflector to the ground.
  • the upper members 411 may be replaced by a vertically extending wall to present an obstacle to the flow of water across the device.

Abstract

L'invention concerne un dispositif destiné à recouvrir un puits d'eaux pluviales et comportant une plaque (10) dimensionnée et configurée pour recouvrir ce puits. Le dispositif comprend également deux mors (11) situés en regard l'un de l'autre, fixés sur la face inférieure de la plaque (10) et venant prendre appui contre les surfaces latérales internes opposées du puits. Au moins l'un des mors (11) est réglable. L'invention vise à empêcher la pénétration de corps étrangers, tels que des particules de couche de base, du gravier, de l'argile, du sable, de la boue, du limon et d'autres matières non désirées, dans le puits d'eaux pluviales et les canalisations en béton utilisées pour acheminer l'écoulement des eaux pluviales en liaison avec le développement urbain, industriel et agricole. L'invention concerne d'autre part un bouchon pour tuyaux d'eaux pluviales, une jupe de linteau d'admission d'eaux pluviales et un déflecteur d'eaux de ruissellement.
