Definitions

  • a LIFT BRIDGE The invention concerns a collapsible lift bridge, particu- larly useful for the temporary connection between surfaces which are separated by an expanse of water, such as is- lands, peninsulas, port entrances, docks and similar. It is a known fact that in various places of the world there are marine, fluvial and lake areas characterized by the presence of lagoons, archipelagos, peninsulas, coves, fiords and similar, where the connection between the va- rious islands, peninsulas and promontories by means of fixed structures, such as bridges or hanging viaducts, is not acceptable since these would ruin the environment.
  • one purpose of the invention is to realize a bridge for the direct connection between areas separated by an expanse of water, which does not ruin the environ- ment. It is another purpose for the installation of said bridge not to compromise the watercraft circulation in and practicability of the expanse of water. It is another purpose for said bridge to be visible only for the time when it is used.
  • a lift bridge which, in accordance with the main claim comprises a viaduct supported by two or more supporting piers and is characte- rized in that each of said supporting piers is telescopic and is composed by at least two elements telescopically sliding one within another because of a fluid under pressu- re inlet inside them through pumping means, the extremity of one of said at least two sliding elements is secured to said viaduct, while the extremity of the other of said at least two sliding elements is secured to the ground.
  • said lift bridge is built to connect with one another two or more surfaces separated by an expanse of water and it can be used both for pedestrian traffic and vehicular traffic, or it can be used for rail transporta- tion.
  • the lift bridge according to the invention comprises a viaduct 2 supported by two telescopic suppor- ting piers 3, each of them being formed by elements, tele- scopically sliding one within another.
  • the bridge is installed in an expanse of water which sepa- rates from one another two surface areas, not represented, and the lower extremity of each telescopic supporting pier 3 rests on the bottom 4.
  • each telescopic supporting pier 3 com- prises a first element 31 connected with the viaduct 2, a third element 33 secured to the bottom 4 and a second element 32 which connects said first element 31 and said third element 33 with each other. It is understood, however, that the number of elements composing each telescopic supporting pier will vary accor- ding to the depth of the expanse of water and, therefore, they can be composed by whichever number of elements, provided that they are more than two. As can be observed in Fig. 3, which represents a section obtained along the longitudinal plan A-A of the bridge represented in Fig.
  • each of the elements composing the telescopic supporting pier 3 presents a tubular shape having a circular section and, in particular, the first tubular element 31 is telescopically connected inside said second tubular element 32 through first interposed sealing elements 35 and said second tubular element 32 is in turn telescopically connected inside said third tubular element 33 through second interposed sealing means 37.
  • Each of said telescopic supporting piers 3 presents, in its own third tubular element 33, a way 38 connected, by means of a pipeline not represented in the Figure, to a pumping system, also not represented in the Figure, which lets in a fluid under pressure, preferably liquid, inside the tele- scopic supporting pier 3.
  • the entire telescopic supporting pier 3 is filled with oil and the fluid, which is pumped through the pumping system, is preferably water taken from the same basin where the bridge is built. Since oil is lighter than water, the two fluids will not mix together, thus yielding the advantage for the inner walls of the telescopic supporting pier to be constantly lubricated, although using a small amount of oil present in the circuit which consists, in fact, just of the oil contained in the supporting piers.
  • the bridge When the bridge is not used, it is lowered by making the tubular elements to collapse one within the other, so that the viaduct 2 can sink in relation to the water surface 21 by at least such a depth, that will permit the sailing of the watercrafts 20.
  • the tubular elements which compose each telescopic suppor- ting pier 3 co-axially collapse one into the other until they are completely lowered and all the cylindrical ele- ments are arranged co-axial with one another, one within the other one.
  • the tubular element secured to the bottom can be completely buried underground, so that once all the tubular elements have collapsed one within the other and the bridge is entirely submersed, the viaduct supported by it can rest on the bottom.
  • the tubular elements By pumping again the fluid into the telescopic supporting piers 3, the tubular elements will reciprocally come out again until the bridge is brought back into the lifted position represented in Fig. 3.
  • the bridge according to the invention achieves the proposed purposes.
  • the fir ⁇ t purpose that has been achieved is that of reali- zing a bridge which can be lifted and which, when it is lowered, is completely submersed by water, so as to prevent the surrounding landscape from being ruined and the sai- ling of watercrafts from being hampered. It is evident that according to the length of the viaduct 2, which is necessary for connecting two banks of the water expanse in which the bridge is built, an adequate number of telescopic supporting piers 3 will be installed, each of them will be composed by a number of tubular ele- ments sliding one within the other according to the depth of the bottom of the expanse of water in which the bridge is set up. Any modification concerning the shape, the dimensions and the number of telescopic cylinders which form the bridge, will fall within the spirit and scope of the present inven- tion.

Abstract

Cette invention concerne un pont levant comportant un viaduc (2) monté sur deux piliers de support télescopiques (3) ou plus. Chaque pilier se compose d'au moins deux éléments (31, 32, 33) coulissant de manière télescopique l'un dans l'autre sous l'effet d'un fluide sous pression envoyé dans ces derniers par l'intermédiaire d'un système de pompage. L'extrémité de l'un des deux éléments coulissants (31), ou plus, est fixée au viaduc (2) tandis que l'extrémité (33) de l'autre desdits éléments coulissants est fixée au sol (4).
