Pathologie des silos
Pathology of silos
Président Directeur Général de la SOPENA SA 5. rue Vincent-Chevard, BP 169, 28003 Chartres Cedex, France
Les silos ont pour but de stocker les grains et autres matières pondérales, et de les abriter des intempéries.
On rencontre le plus souvent des désordres mettant en cause l'étanchéité des parois : infiltration d'eau au droit de la galerie enterrée, gênant le transfert des grains par tapis roulant, ou passage d'eau au travers de la paroi, mouillant le grain stocké.
On rencontre également des fissures, entraînant ou non des infiltrations d'eau, causées par des insuffisances d'armatures, pouvant conduire à des ruptures.
Enfin, on rencontre des désordres consécutifs à un tassement du dallage et des fondations.
Tous ces désordres sont à apprécier, en fonction de l'usage du silo, et de la gêne qui s'ensuit pour son exploitation.
Abstract
Silos are used to store the grain and to shelter it from the bad weather.
Most often we meet with disorders questioning the water tightness of the walls : infiltration of water near the buried gallery, hindering the transfer of the grain by travelling band, or passage of water through the walls wetting the stocked grain.
Cracks are also met with, leading wheter to water infiltrations or not, caused by insufficient reinforcement which may lead to ruptures.
Finally disorders consecutive to a firming of the pavement and of the foundations are met with.
All these disorders are to be estimated according to the use of the silo and of the trouble which follows concerning its exploitation.
