Definitions

  • the present invention relates to a method for the construction of a protection structure for a structure such as a bank, a pier or the like.
  • the perré has consisted of cut and masonry granite or alternatively stones filled with bituminous mastic. This coating is generally placed on a rockfill in various materials covering the slope formed from the natural ground. The foot of the perré abuts against the foundation and is covered like this one by a reinforcement embankment.
  • the structure thus formed generally withstands the stresses to which it is subjected by moving water: current, waves, trunnions, tide ... whether it is sea water or water from sensitive rivers. at the tide.
  • the riprap is strong and rigid, that it is one with the foundation, that it is reliable.
  • the execution of the pier must be fast, efficient and inexpensive. It must be able to be interrupted without damage when the water rises. It should only require a reduced number of staff.
  • the present invention aims to achieve this goal by implementing the teaching provided by European patent application No. 0 138 259 to produce a filter bed on a reinforced embankment embankment.
  • the solid mass is then constituted by a sheath with multiple conduits extending along the slope and filled with an injectable material such as expanded clay granules.
  • the method also consists in: - to deposit freely on the riprap before the sheath, a filter cloth (17) letting the water pass but not the fines, - to close the conduits against the foundation (10) and to file (in 19) the upper part at least of the sheath and the canvas in the structure, - pouring concrete into said conduits, - and to close them when they are full.
  • Unconsolidated concrete thus enclosed in the sheath therefore does not risk being diluted in seawater or river water when the riprap is covered. He therefore continues to take hold of the low water containers.
  • the method consists in providing: - between the pipes filled with concrete and the filter cloth of small tunnels collecting the water which filters through it and directing it downwards, - and between the concrete-filled conduits on the side of their visible part of the channels carrying the flowing water.
  • the method can also consist in introducing into each of the conduits of the sheath a reinforcement by providing means for keeping the latter spaced from the walls of the conduit considered during the pouring of the concrete.
  • the reinforcements of said conduits are fixed to transverse reinforcement elements inserted in said beam and projecting from this parallel to the slope.
  • this riprap comprises, in recovery of the steep riprap of the structure, concrete beams coated with conduits flexible joined together and placed on a filter cloth, these coated beams delimiting between them small underlying tunnels collecting filtering water and overlying channels conveying runoff water.
  • the sloping beams wrapped in concrete contain at least one reinforcement intended to be fixed on at least one reinforcement element plugged into a foundation beam.
  • the reinforcements of the wrapped concrete sloping beams are provided with spacers making it possible to separate them from the wall of the flexible conduit enveloping said beams.
  • the structure to which the method of the invention applies is a pier 1 on which a pavement 2 is built, bordered at least on one side by a sidewalk 3 and a concrete parapet 4.
  • the jetty is built in the form of an embankment with natural terrain 5 which is covered by riprap 6.
  • the sloping surface 7 of riprap which connects the traffic surface of the carriageway 2 to bottom 8 of the river or the sea, is coated with a riprap 9, the foot of which abuts against a foundation 10.
  • the bottom of the riprap 9, the foundation 10 and the neighboring part of the bottom 8 are covered by a reinforcing fill 11 intended to protect this area from the devastating action of the sea or the river.
  • the pierced 9 is constructed by means of a flexible sheath 12 formed by two sheets 13 and 14 connected together by fixing lines 15 parallel.
  • the single or multiple fixing lines are, in the example chosen, seams, but can also be stapling, welding, gluing lines ...
  • the sheets 13 and 14 are advantageously made of woven polypropylene fabric.
  • the sheath 12 delimits parallel conduits 16 and is spread over a filter cloth 17 covering the sloping surface 7 of the riprap of the structure so that said conduits extend along the slope and are open at the top , closed at the bottom.
  • the lower edge of the sheath 12 can be sewn to close the lower end of the conduits 16 and the latter is brought to abut against the foundation 10, while the said sheath is laid flat and freely on the filter cloth 17 fixed to the riprap 6.
  • conduits 16 are filled with concrete 18 and follow the shape of the riprap through the filter cloth 17.
  • the upper end of the conduits full is closed by any suitable means, such as staples, and the sheath 12 is fixed on the riprap 6 for the filled part only by means of plugs 19 planted at the head (FIG. 1) and possibly on the sides.
  • the first empty duct which presents itself is free to inflate and deform; its upper mouth can then be opened to introduce the pipe of a concrete pump and the filling of the conduit with concrete can be carried out; the mouth is closed and fixing cards 19 are planted.
  • This filling method progresses step by step and the riprap is thus formed by "molding" on the riprap.
  • Construction work can be continued as long as the sea or river remains low. By cons, as soon as it begins to cover, it is necessary to interrupt said work. However, the sloping beams 18 of concrete not yet set and not consolidated, are protected by the sheath 12 and withdrawn from the particularly devastating action of the sea or the water which covers.
  • the beams 18 consolidate and form a solid and resistant structure.
  • the beams 18 delimit between them tunnels collecting the water which re-emerges from the riprap 6 and crosses the filter cloth 17, which opposes the passage of fines and prevents degradation of the work. True protection of the structure is accomplished.
  • the beams 18 delimit between them overlying channels 21 which apparently and downwardly convey the reflux and runoff water.
  • one or more frames 22 are slid into the conduits 16 while the sheath 12 is deployed step by step either on the sloping surface 7 of the riprap, or on the roadway 2 before it is placed on said surface.
  • the frames 22 are fitted with spacers 23 suitably spaced and perforated, before being inserted into the conduits 16.
  • a reinforced concrete beam (FIG. 5).
  • the latter then comprises a plurality of aligned sections of concrete 24, filling flexible envelopes 25 and placed under pressure against one another. Longitudinal reinforcements 26 extend through said sections. The envelopes are closed.
  • This beam 10 is bristling with reinforcing elements 27 protruding above and parallel to the sloping surface 7 of the riprap 6 of the structure.
  • the elements 27 are inserted into the wrapped sections 24 of the foundation beam 10, before setting the concrete and are centered on the locations which the lower ends of the conduits 16 of the sheath 12 will occupy.
  • this sheath During the installation of this sheath, the lower edge of the latter is disjointed in the center of each conduit to exit from the conduit considered the armature 22 and connect it by a ligature or staples 28 to the corresponding element 27. Then, all the conduits are re-threaded on the reinforcement thus joined. The sheath is stretched upwards. Concrete is poured into the conduits one after the other. The beams thus formed are inserted.
  • a fitting 29 (FIG. 1) is placed between the parapet 4 and the upper ends of the beams 18.
