The couneetkm means of the sealing device are firmly attached to the tloid-'tighl seal imd saitoble for being connected so the reinfercexnent cage. They ate suitable, generally by deforming and/or moving, for modifying the total width of the sealing device, measured In a direction not parallel to the principal dirsedon in which the seal extends» generally in a lateral direction perpendicular to the principal direction, The connection means· are Interleaved completely or partially in this direction, between the seal and the reinforcing cage.

It will then be. esderslood ihat fey modifying the width of the sealing device, -attached to the r«-infurcement cage, the separation distance -between the reinforcing cage and-the-seal Is also modified» and foerelore .the total width of a -structure formed fey rite reinforcing cage and the sealing device.

It should fee noted that, In one embodiment, the scaling device «au- dicitide at least two seals eouaecföd to .common or specific connection means, sealing then being ensured redundantly fey stod seals.

The connection means -generally comprise nt least one-adjustment element, deformable aod/or-mounted movafely with respect to the .fluid-tight seal, foetorably, however, they comprise a plurelify of afelustmeot elements •distributed, in the principal direction of the device,

Accotdfog to one example, the eotmeoitoa moans can. also comprise an elongated attachment support to which arc attached the adiusttnent etonmuis, said support- being suitable for being attached to the refoforeasseat cage. Tito support can tor example he attached to the mittforcement cage by welding or by clipping. These dispositions allow the sealing device to be adapted to reinforcement cages with -variable eonfigomtions, particularly its regards I he spacing of the reinforcement.

The presens presentation relates, secondly, to a strttefese lot a reinforced concrete element molded,itrto ground, tor example a panel or a pile, comprising a reinforcement cage, and characterised in fettf it. also comprises at least one seolittg device as previously defined attached to fee retnfercetneot cage, to connection means being suitable for adjusting to separation distance between the fifed-iofet seal and the reinlhrcemeni cage, it is uoderstood feat to strncture thus ds.ffeed is designed, to be introduced into an excavation fe the ground before being embedded m concrete to fenn a reinforced concrete clement, parttetthtriy a molded' wail, panel or a pile· of a curtain of secant or contiguous odes.

Such a structure has an adjustable width, which allows, in a single handling phase, the excavation to. he equipped with, a reinforcement cage and at least one device providing a fmki-ught connection with .an. adjoining «oncrere clement.

In the present presentation, fee principal duectien of the structure is defined as fee direction in which it is designed to be lowered into the excavation prior te ooneretihg.

Moreover, the intern! direction of fee structure is defined its the direction perpendfetdsr to fee principal ducefton and oriented us fee gênerai direction of fee w»tk tue the ferecnon in winch fee unitary elements are aligned). Once the struefere is Introduced Into the excavation,
