Definitions

  • the present invention relates to an elongated underground structure of constant section having a reinforced concrete structure surrounding at least the part of the cross section of this structure forming a free volume above its bottom, and to a process for manufacturing this structure. work.
  • this solution is supposed to solve the problems inherent in the drilling of an underground passage under a traffic lane in service by avoiding the slowing down of traffic during the works, its implementation requires considerable means, in particular an installation of high power jacks as well as works capable of serving as support for these jacks.
  • the continuous advance of the reinforced concrete structure also poses problems with the length of jacks, the hollow structure advancing while the supporting structures remain fixed.
  • the necessary pressure is considerable taking into account the friction surface which increases as the structure is pushed in. Consequently, this solution poses fairly complex implementation problems which make it costly to produce due to the additional work caused by the structures serving to support the jacks. If it is undeniable that such a solution makes it possible to solve the problem of piercing a passage under a traffic lane in service without significant slowdown in traffic, it is therefore at the cost of significant practical difficulties and an increase construction costs.
  • DE-A-1 759 309 also relates to the construction of an underground structure produced using tubes placed side by side in the part intended to form the ceiling of the structure and linked together by elements of tension anchored to these tubes.
  • the establishment of these tubes is carried out by sinking into the ground after which a volume is excavated below these tubes.
  • these tubes are supported by props in the form of frames arranged along the cross section of the structure.
  • These tubes are filled with prestressed concrete and the spaces left free between them are filled with shotcrete.
  • the interior of the structure is then lined with traditional masonry. This document does not specify what the supporting structure of this structure consists of or the nature of the interior masonry, simple coating or reinforced wall.
  • this load-bearing structure consists only of tubes filled with prestressed concrete due to the lack of cohesion of such a structure, each beam being independent of the adjacent beam and the absence of lateral load-bearing walls. .
  • the masonry work necessary for finishing and the nature of which is not specified, should be significant.
  • the installation of tension elements anchored to these tubes to link them requires tubes of sufficient diameter to allow a man to enter to do this work.
  • these tubes are then filled with concrete, the volume of concrete required is considerable.
  • These huge concrete cylinders rest, moreover, on the masonry structure which should be load-bearing and therefore require significant formwork and reinforcement work. This is a technically and economically unsuitable solution to the problem of building an underground structure.
  • the object of the present invention is to remedy these drawbacks at least in part and at the same time offer a technically advantageous solution by itself, both for making underground passages under traffic lanes in service and for drilling and construction of any other elongated underground work of constant section.
  • the present invention firstly relates to an elongated underground structure of constant section as known from US-A-4009579 and having a reinforced concrete structure surrounding at least the part of the cross section of this structure forming a free volume above its bottom, this structure comprising cylindrical concrete beams injected into tubes extending parallel to each other in the longitudinal direction of this structure, as well as stays in the form of frames arranged transversely to the interior of this structure, characterized in that these tubes are spaced from one another and are interconnected by lost formwork elements, each of which is engaged with two adjacent tubes to delimit the external face of a wall of reinforced concrete , delimited internally by other lost formwork elements disposed between these tubes and said struts spaced longitudinally from each other.
  • This invention also relates to a method of constructing this underground structure. characterized by the fact that successively, by turning around the straight section of the structure, said tubular elements and said lost formwork elements connecting these tubular elements, of a certain length, are repeated and repeated if necessary this cycle until the total length corresponds to that of the structure, said tubular elements are filled with reinforced concrete, the space delimited by these tubular elements is excavated and the lost formwork elements connecting them, the said props are placed as the said structure is excavated, the lost formwork elements are inserted between these struts and these tubular elements and the spaces delimited by the lost formwork elements connecting the tubular elements and those tangent to them are filled with reinforced concrete .
  • the structure illustrated in figs 1 and 2, consists of an underground passage which includes a reinforced concrete structure 2 surrounding the cross section of this passage 1.
  • This reinforced concrete structure is formed on the one hand inside 'tubular elements 3 serving as lost formwork, extending longitudinally at passage 1 and distributed around its cross section, as illustrated in fig. 2.
  • this structure is delimited internally by a lost formwork 4 tangent to the tubular elements and formed by metal profiles protected against corrosion and externally, by sheet piles 5 whose longitudinal edges have profiles 5a engaged in slides longitudinal 6 fixed in substantially diametrically opposite positions against the external face of each tubular element 3.
  • the side walls and the ceiling of this passage are formed by profiled sheets 8 fixed inside the stays 7 in the form of frames.
  • the bottom of the passage receives a raft covered with a covering 9.
  • the method of construction of this passage consists in first of all pushing in the tubular elements 3 and the sheet piles 5 one after the other over a certain length.
  • the tubular elements 3 and the sheet piles 5 can moreover be dimensioned with the length corresponding to that of the desired insertion, for example 10 to 12 meters.
  • the slides 6 and the edges 5a of the sheet piles 5 are mutually engaged to guide them as they are driven into the ground.
  • This depression is achieved using a pneumatic horizontal threshing apparatus 10 illustrated schematically in FIG. 3.
  • This device comprises a cylinder containing a free piston of 20 to 160 kg driven in an alternating movement at a frequency between 320 and 460 Hz depending on the model, supplied with pressurized air supplied by a compressor 12, at a pressure of 6 bar.
  • the air consumption is between 1 and 6 m 3 / min and the force developed is between 7 and 85 kpm.
  • the diameter of the cylinder enclosing the piston is from 70 to 155 mm depending on the model and its end ends in an adapter cone 11 to the tubular element 3 between 140 and 400 mm in diameter.
  • This threshing device of Soviet construction, exists in four models sold in Switzerland by the house R. Lehmann AG 8606 Werrikon b / Uster under the references IP 60. IP 4605, IP 4603 and IP 500.
  • the apparatus 10 For the insertion of tubular elements 3, in this example steel tubes 200 mm in diameter, 12 meters in length and 4.5 mm in wall thickness, the apparatus 10 is positioned in the extension of the longitudinal axis of a tubular element 3 and the cone 11 is applied against the end of this tubular element 3, for example using tension cables 13 anchored in the ground and hooked around the base of the adaptation cone 11. We then supply the 'apparatus 10 in compressed air supplied by the compressor 12. As soon as the first beats, the adapter cone gets stuck in the opening of the tubular element 3, so that the tensioning cables 13 become unnecessary.
  • the front end of the tubular element 3 can be left open, in which case the earth fills the interior of this tubular element as it is pushed in.
  • the front end of this tubular element 3 can be provided with a conical cover 14, (fig. 4) which avoids having to remove the soil from the interior of this tubular element 3 thereafter.
  • fig. 5 another variant according to which the front end of the tubular element 3 is surrounded by a ring 15 intended to cut in the ground a hole of diameter slightly greater than that of the tubular element 3, which makes it possible to reduce the friction forces and is useful in particular for drilling relatively long passages.
  • a sheet pile 5 is arranged by engaging its profiled edge 5a in one of the slides welded along the tubular element.
  • the adapter cone 11 is replaced at the front of the apparatus 10 by a slot template 16 (fig. 6) intended to receive the rear edge of the sheet pile 5 and the latter is pressed in the same manner as the tubular element 3.
  • the distance between the tubular elements 3 is 65 cm.
  • each tubular element 3 and each sheet pile 5 are pressed in alternately until the entire straight section of the underground passage 1 is delimited by this structure.
  • the following operation consists in emptying the tubular elements 3 in the event that these were not provided with a conical cover 14 such as that illustrated in FIG. 4.
  • a pressurized water jet is advantageously used, which makes it possible to fluidize the earth and to entrain it outside the tubular conduit. You can also use compressed air or push the earth plug with a piston.
  • the realization of the underground structure object of the invention therefore does not require any particular accessory infrastructure except supports for the tubular elements and sheet piles during the initial phase of the threshing process.
  • the advance of the tubular elements by threshing is between 8 and 12 cm / min so that a tubular element of 12 m can be inserted in about two hours.
  • this invention is not limited to a work of rectangular section.
  • the reinforced concrete structure extends around the entire straight section of the structure, the bottom of this section may not include such a structure since this party is not coerced.
  • the variant illustrated in FIG. 7 shows an underground structure whose section is substantially semi-circular.
  • the reinforced concrete structure is identical to that of the passage illustrated in fig. 2 and comprises tubular elements 3 ′ alternating with sheet piling 5 ′, the structure being internally limited by lost formwork elements 4 ′ slipped between the tubular elements 3 ′ and props each formed by a hoop 17 whose ends are maintained separated by a spacer 18.
  • the bottom of the structure does not have a reinforced concrete structure but is simply covered with a slab receiving a coating 9 '.
  • This variant is obviously applicable to the example of FIG. 2 as it would also be possible to produce the variant of FIG. 7 with a reinforced concrete structure with tubes and sheet piles around the entire cross section of the structure.
