Definitions

  • the invention relates to the field of civil engineering and relates more particularly to a method for ensuring mechanical continuity and the transmission of forces between two adjacent panels of a reinforced concrete wall molded in the ground.
  • the object of the invention is to provide a new process for ensuring mechanical continuity and the transmission of forces between two adjacent panels of a reinforced concrete wall, molded in the ground, which is free from the above-mentioned defects and constitutes remarkable technical progress. .
  • this method consists in drowning in the concrete of a panel n in progress the bodies of a plurality of jacks distributed at intervals over the height of the panel and arranged at the end of said panel adjacent to the panel n + according to be produced, the rods of the jacks being in the retracted position and their ends being brought in the immediate vicinity of the shuttering means of the end of the excavation in which the panel n is poured, then, after sufficient taking of the concrete from this panel , execution of the excavation of the next panel n + and removal of the formwork means provided at the end of the excavation of the panel n, to deploy the rods of the jacks so that they penetrate into the excavation of the panel n + 1 next to achieve and, finally, to concretize the excavation of said n + panel, thus embedding the rods of the jacks in the concrete.
  • the jacks deployed act as reinforcements ensuring the transmission of forces from one panel to another.
  • the cylinder body and the cylinder rod at their opposite ends, with flanges or end plates.
  • the cylinder body could be provided with protrusions intended to improve the adhesion between the concrete and the cylinder body, the rod being the only one provided with a flange or anchoring plate at its free end.
  • the cylinder body could be fixed to irons or anchor bars which will themselves be hubed in the concrete.
  • each reinforcement cage can carry a series of jacks at one of its ends and be provided with adequate free volumes at the other end to receive the rods of the jacks of the adjacent cage during their deployment.
  • one out of two reinforcement cages can carry a set of jacks at each of its ends, the adjacent cages being, on their side, provided with adequate free volumes.
  • the jacks provided at the two ends of the jacking cages can be connected two by two by a connecting member, such as a steel bar, ensuring their anchoring.
  • single-acting or double-acting cylinders can be used.
  • single-acting cylinders it must be ensured that, when the rods are deployed, for example under the effect of compressed air pressure or another pressurized fluid, the piston of each cylinder comes into abutment against the bottom of the cylinder in order to be certain that the forces will be transmitted from the rod to the body of the jack and vice versa.
  • double-acting cylinders it is possible to exert a prestress, after hardening of the concrete, in order to put in tension the rod of the jack.
  • the durability of this prestressing will be ensured by the use as pressurizing fluid of the jack of a hardenable fluid, such as a cement grout without shrinkage, which will take hold in the cylinder of the jack.
  • a hardenable fluid such as a cement grout without shrinkage
  • Such a curable fluid can also be used in the case of a single-acting cylinder.
  • the anchoring zones of the body and of the rod of the jack may be reinforced transversely by steels provided for this purpose in the cages, so as to respect the customs in terms of concrete.
  • the cylinders can be of very ordinary quality, or even inferior, since they are intended to operate only once.
  • the jacks can be placed horizontally and parallel to the faces of the diaphragm wall or in any other direction desirable from the point of view of the transmission of forces.
  • the cylinders can be positioned in the middle plane of the panels if it is a question of transmitting a simple traction.
  • the rods of the cylinders will be advantageously protected from corrosion at the crossing point of the joint.
  • the cylinders will be sized according to the forces to which they will be subjected, as is obvious.
  • Figures 1a to 1e are schematic plan views illustrating the method of the invention.
  • Figure 2 is a schematic sectional view along line E-E of Figure 1e; and
  • Figure 3 is a schematic view illustrating a variant of the method of the invention.
  • FIGs 1a to 1e and 2 illustrate the implementation of the method of the invention.
  • Figure 1a we see an excavation 1n carried out in a conventional manner under bentonite mud, in which will be poured the panel n of the diaphragm wall.
  • a 2n profiled formwork is put in place.
  • a reinforcement cage 3n is put in place (shown in a very simplified manner) to which a plurality of single-acting cylinders 4n are fixed in the retracted position.
  • the jacks 4n comprise a body 5n and a rod 6n carrying at their opposite ends flanges or anchoring plates 7n and 8n, respectively.
  • the jacks 4n are positioned at intervals, for example, regular over the height of the cage and in the region of the cage adjacent to the formwork 2n.
  • the cylinders of the jacks are supplied with pressurized fluid through a conduit 9n.
  • the cage carrying the jacks being in place, a light blow of compressed air is sent into the jacks so that the plates 8n come into abutment against the formwork 2n, then we proceed to concreting the excavation 1n ( Figure 1b).
  • the cage 3n, the conduit 9n, the bodies 5n of the jacks and their plates 7n are embedded in the concrete, while only a small portion of the rods 6n is coated, the plates 8n flush with the concrete.
  • FIG. 3 illustrates the variant of the method of the invention in which double-acting cylinders 14 are used instead of single-acting cylinders 4.
  • jacks are used, the cylinder of which has two chambers which can be pressurized by the conduits 9n and 11n respectively, the procedure being as described with reference to FIGS. 1 and 2, except that in the sequence illustrated by FIG.
  • the rods are not fully deployed but a certain residual stroke is left, for example by providing a stop 12n on the rod of each cylinder, and that, after setting the concrete poured into the excavation n +1, the rod of each of the cylinders is put in traction by injecting through the conduit A a hardenable fluid under pressure, such as a cement grout without shrinkage, the grip of which will ensure the durability of the tensile force applied to the rod of each of the cylinders.
  • FIG. 3 illustrates the jacks after they have been pulled.
