Drainage near the Rhone, Lyon, France

The Project:

The project is based in the downtown of Lyon and at the corner of a crossroads. Urban density is high and the lanes are nearby. The site is located approximately 350m from the Rhone river. The work consists of creating a well-point system about 1,2 m deep, so that the soil reinforcement can be completed and the excavation of bottom material be excavated properly after the rubble have become dry.


The Problem:

The complexity of the project is caused by continuing reinforcement of the soil under the groundwater level and excavation of rubble to allow the creation of a second level of basement. All these works can only be carried out in a dry environment, it was necessary to establish a system of continuous pumping during the work under this condition.


The Solution:

Our client has completed the installation of strainer wells and four Contractors' pumps Tsurumi KRS822 were implemented. They pump about 200 m3/h to 23m of head. The wells are connected by pipes of DN150. This facility operates 24/7 and it is under constant surveillance. To date no action on the pumps had to be done.

Aplinkoje, kur yra braižančių dalelių ir korozinių medžiagų, tam tikri komponentai natūraliai dėvisi greičiau. Eksploatuojant pirmiau minėtomis sąlygomis, sparčiau dėvisi sparnuotė, maišytuvas, siurbimo plokštė, veleno sandariklis, alyvos žiedas, mechaninis sandariklis, siurblio korpusas, koštuvas, variklio korpusas ir išleidimo mova. Atsižvelgiant į darbines sąlygas, šių dalių eksploatacija gali gerokai sutrumpėti ir nesiekti įstatymais nustatyto garantijos laikotarpio.
Tokiu atveju reikia atidžiai perskaityti mūsų bendrąsias sąlygas ir nuostatus, kuriuos, gavę atskirą užklausą, galime išsiųsti paštu.
