Definitions
- a barrier for protection against flooding incorporating the following pair of essential features which, operating together, enable it by rotation about its lower bottom edge to be lowered to, and rest upon the surface beneath a body of water while the surface of the water above is at a safe level, and to be raised to a position so as to retain the water on one side of it at a safe level while retaining water on its other side to a higher level:
- a - a buoyancy chamber the internal volume of which is such that the weight of the barrier is equal to the weight of the volume of water displaced by it when fully immersed, and the position of which within the barrier is such that its centre of buoyancy is above and towards the upper crest of the barrier relative to its centre of mass, excluding any mass of the barrier' s 'balancing mechanism' movable relatively to that mass centre, and:
- B - a balancing mechanism enabling the centre of gravity of the barrier as a whole to be moved towards or away from the barrier's crest across the vertical through the centre of buoyancy to provide a turning moment either to lower, or raise the barrier.
- the totally immersed barrier having a density the same as that of the liquid in which it is immersed, floats 'weightlessly' within the liquid, its 'free' attitude being determined by its centre of buoyancy being vertically above its centre of gravity. For erection, or maintenance, it is, therefore, very light, easy to move, manoeuvre and manipulate, and imposes almost no load upon its foundation, or, when lowered, upon the bed material.
- the flood wave, or tidal surge When functioning as a barrier against flooding, the flood wave, or tidal surge, itself, provides both the horizontal force and moment required to maintain the barrier in the raised position, provided that in the fully raised position it is inclined towards the wave, or surge.
- the barrier acts as a cantilever, transferring only the differential hydrostatic force and moment directly to the foundation as internal transverse shear, longitudinal compression and bending moment. The resulting pressure of the base of the barrier upon the inclined face of the foundation provides an effective seal.
- the barrier accordingly rotates to float with its crest just submerged when the water levels either side equate. Lowering the barrier to rest upon the 'bed', or 'floor' is achieved by appropriate mechanical adjustment of the balancing mechanism.
- the barrier may be of any structural material possessing the necessary strength in
- the structural section may be any allowing of the two essential features of buoyancy chamber and balancing mechanism, having a section modulus such that all stresses within the material shall comply with applicable safe limits, having regard to economic factors of quantities of material, simplicity, speed and ease of manufacture, fabrication, assembly and installation, as also any environmental, or aesthetic restraints that might be imposed.
- an auxiliary buoyancy chamber at the upper, crest end of the barrier, in balance when partially filled, and alternately exhausted or flooded to raise or lower the barrier;
- the essential buoyancy chamber itself, may be mounted so as to be movable along the central
- auxiliary buoyancy chambers of equal volume at each end of the essential chamber both half filled with a suitably non-corrosive liquid when in balance, all their combined content being alternately transferred to the lower, or upper chamber to raise, or lower the barrier.
- Important objectives of the operating principle described are, firstly, to rninimise the energy and power needed to raise and lower the barrier, and secondly, to ensure that the barrier remains fully raised and effective for the duration of a flood, or surge, without need of external support or intervention should some failure, malfunction, or other suchlike emergency occur, as the barrier, once raised, is supported by the flood, or surge, itself.
