BORED LARGE DIAMETER HORIZONTAL PIPES

LE FONCAGE HORIZONTAL DES CONDUITES DE GROS DIAMETRE

OBSTRUCTIONS IN THE SUBSOIL OFTEN REQUIRE CONDUITS TO BE CONSTRUCTED AT A LOWER LEVEL. SUCH DRIVING OF HORIZONTAL TUNNELS CONSTITUTES, WHEN REQUIRED TO BE CARRIED OUT WITHOUT AFFECTING THE USE OF INSTALLATIONS IN SERVICE, A TECHNIQUE OFTEN UTILISED. THE ARTICLE DESCRIBES THE TECHNIQUES OF BORING AND THEN THE RELATIONS AND CONSTRAINTS WHICH EXIST BETWEEN SOIL AND SURCHARGE, AND ALSO ACTIVE EARTH PRESSURE. THE CONDITIONS UNDER WHICH BORING CAN BE CONSIDERED NECESSARY OR DESIRABLE AS WELL AS THE APPROXIMATE COST OF THE WORKS ARE EXAMINED.
