Definitions

  • the invention relates to a method of making a coated tunnel or a coated excavation, of circular section, according to which an excavation is dug using a suitable device and a covering is placed inside this excavation.
  • the invention relates in particular to the production of a coated microtunnel, that is to say a small diameter tunnel among other things in the case where human intervention is not possible.
  • coating elements are pushed one behind the other, from a starting chamber, behind a microtunnelier, thus ensuring its advancement.
  • the invention aims to remedy the above drawbacks and to provide a method for carrying out coated excavations in a simple manner in convergent soils located at great depth.
  • the laying of the covering comprises a stage during which tube elements cut along their length and folded back on themselves are introduced through the tube elements already in place up to the level of their location where they open by their own elasticity or are opened by an appropriate device.
  • the tube elements are held in the folded position by a appropriate device and are released at their final location.
  • the tube elements open or are open at their location into an open position in which a longitudinal opening remains, these tube elements in place can then close under the action of soil convergence.
  • the tube elements which are pushed can then be provided with a guide to guide them when they close under the action of the convergence of the ground.
  • the laying of the covering comprises a second step during which a final covering is put in place along the above-mentioned covering.
  • this final coating comprises elements which are pushed through the tube elements already in place.
  • the elements of the final coating can have a diameter equal, with the tolerances, to the inside diameter of the tube elements in the closed final position.
  • the final coating can be placed in the form of conventional tube elements which are welded together to form a waterproof coating.
  • the final coating or a part of it can be used to push the last tube elements to be installed through the tube elements already in place.
  • the figures relate to the realization of an excavation in the form of a horizontal microtunnel with a diameter between 0.5 and 1.5 m, from an already existing main gallery 16, in a clay soil 1, with large depth.
  • an excavation device that is to say a microtunnelier 2 is used consisting of three stations, that is to say an anchoring station 3, a pushing station 4 and a station excavation 5.
  • the microtunnelier 2 With the aid of the anchoring station 3, fitted with hydraulic jacks 6, the microtunnelier 2 is anchored in the ground 1.
  • the excavation station 5 composed of a drilling instrument with global attack is advanced, during digging, using the pushing station 4 also provided with hydraulic cylinders.
  • the anchoring station 3 When the hydraulic cylinders of the pushing station 4 are at the end of their travel, the anchoring station 3 is released and retracted towards the excavation station 5, using the hydraulic cylinders of the pushing station 4. The place necessary for the location of an element of an auxiliary covering 7 is thus released at the rear of the microtunnelier 2.
  • the above procedure is repeated, starting with a new anchoring of the microtunnelier 2.
  • the covering is placed in two stages, that is to say a first stage during which a first covering or auxiliary covering 7, intended to take up during the construction of the tunnel, the pressures of the ground 1 (of the order of 1 MPa), is put in place and a second stage during which a final coating 8, intended to take up the pressures of the soil 1 in the long term (of the order of 5 MPa), is put in place.
  • the auxiliary coating 7 is formed of tube elements 9, for example made of metal, of a thickness of between 5 and 10 mm, and therefore somewhat elastically deformable, which are sectioned over their entire length and folded back on themselves, as as shown in Figure 2.
  • tube elements 9 can be routed, one behind the other, in the folded position, to the level of their location by pushing them through the tube elements 9 already in place, as shown in Figure 2.
  • the tube elements 9 open by their own elasticity and return to their initial position, that is to say the position they had after their cutting, as shown in Figure 3, thus leaving a longitudinal opening 10.
  • Each element of tube 9 is provided on its outer face at the longitudinal section, with a guide 11 formed by a curved rim. The function of this guide is the subject of another paragraph.
  • the auxiliary covering 7 is laid as follows: a first tube element 9 is placed in the microtunnel; the following tube elements 9 are previously folded back on themselves and introduced one after the other, as shown in section in FIG. 2, from the main gallery 16, as the microtunnelier 2 excavates.
  • the tube elements 9 are thus pushed to the level of their location, using a pushing station 13, placed in the main gallery 16.
  • the tube elements 9 are made integral by suitable wedging devices.
  • the tube elements 9 open by elasticity, as shown in FIG. 3, leaving a longitudinal opening 10.
  • the above guide 11 limits the movement of the walls of the tube element 9.
  • each tube element 9 is such that one edge of the opening 10 is provided with a V-groove 14 and that the other edge of this same opening 10 has a corresponding end 15 in V, such that shown in detail in Figure 4.
  • This sealed final coating 8 is intended to take up the pressure exerted by the ground 1 in the long term.
  • This final coating 8 has an outside diameter equal, with tolerances, to the inside diameter of the auxiliary coating 7 with the tube elements 9 in their closed position.
  • the final covering 8 is introduced in the form of tube elements 12 which are pushed, one after the other, from the main gallery 16, using the pushing station 13. As they are introduction, the tube elements 12 are welded to ensure their tightness.
  • the final coating 8 can be used to push the last tube elements 9 to their location.
  • the microtunnel is produced as soon as all the tube elements 9 are at their location and all the tube elements 12 of the final covering 8 have been introduced.
  • the excavation does not necessarily have to be a horizontal microtunnel. It can be a tunnel, a gallery or any horizontal or inclined or even vertical excavation.
  • the microtunnelier 2 can, as the case may be, be replaced by another suitable excavation device.
  • the tunnel boring machine or other excavation device may as well rest on the tube elements 9 already in place.
  • the anchoring station 3 can be eliminated or replaced.
  • the tube elements 9 of the first coating instead of opening by their own elasticity at their final location, are opened mechanically, for example by jacks. These tube elements 9 are then in the stable state in their folded position.
  • tube elements 9 need not necessarily be made of metal. They can for example be made of synthetic material.
  • tube elements 12 of the final covering 8 need not necessarily be made of metal. They can for example be concrete.
  • this final coating 8 can in certain variants be omitted or replaced by the injection of concrete, for example outside around the tube elements 9 of the auxiliary coating 7 put in place.
