ABSTRACT: The Highbury Interceptor Siphon consists of three concrete pipes conveying sewage under the North Arm of the Fraser River from Vancouver to the Iona Island Wastewater Treatment Plant in Richmond, BC. The eastern pipe of the siphon was successfully lined with the Cured-In-Place-Pipe (CIPP) method in the summer of 2009. Jet grouting was used to create an access chamber to the pipe, located about 9 m below ground level on the Iona site. The nature of the soil, Fraser River sand overlying deep silt, and the presence of a high water table ruled out conventional dewatering and construction methods for the access chamber. Jet grouting was chosen as the most viable method to construct the access chamber in these sub-surface conditions.

RÉSUMÉ: Le Siphon Highbury Interceptor se compose de trois tuyaux en béton qui transportent les eaux d'égout sous le bras nord du fleuve Fraser de Vancouver à l'usine de traitement Iona Island à Richmond, Colombie-Britannique. Le tuyau oriental du siphon a été correctement aligné avec la technologie de chemisage (CIPP) au cours de l'été 2009. Jet Grouting a été utilisé pour créer une chambre d'accès pour le tuyau, situé à environ 9 m au-dessous du niveau du sol. La nature du sol, sable du Fraser River et limon profond, et la présence d'une nappe phréatique très proche du sol, exclut les méthodes classiques de construction et d'hydro-extraction pour la chambre d'accès. Jet-Grouting a été choisi comme la méthode la plus viable pour construire la chambre d'accès dans ces conditions souterraines. 1 INTRODUCTION
