<p>The invention relates to an elongated housing (1) intended to withstand an internal pressure which may exceed 10 bars and forming a tubular sealed space (A) having a truncated cross-section, comprising a lower portion formed of a rigid concrete slab (2) resting on the ground and an upper portion (3) consisting of a thin metal wall shaped like a curved vault extending between two side extremities (31, 31') parallel to the longitudinal axis and each connected to the slab (2) by means of a longitudinal connection part connected tangentially to the side extremity (31, 31') of the vault (3). According to the invention, the upper face (22) of the slab (2) has a width substantially equal to the spacing between the two side extremities (31, 31') of the curved vault (3) and each connection part is comprised of a flat plate (4, 4') which extends in the prolongation of the vault (3) and is applied from the outside against the corresponding side face (23, 23') of the slab (2), each plate (4,4') being associated with support means (5, 42) capable of opposing the slipping of said plate (4, 4') along the corresponding side face (23, 23') of the slab (2) caused by forces (15) due to internal pressure and to the separation of said plates (4, 4') as a result of external forces (13).</p> |
