Definitions
- the invention relates to a method of making a tunnel. paved or coated excavation, where a circular section excavation is dug in the ground at using a suitable device and a covering is placed inside this excavation, the laying of the covering including the introduction of the coating portions one after another, in reduced diameter in the part already covered with the tunnel, and their extension to their location final.
- the invention relates in particular to the production of a coated microtunnel, i.e. a small tunnel diameter among others in the case where human intervention not possible.
- US-A-3,645,102 describes such a method in which coating portions forming part of a ring are introduced into the already coated part of the tunnel.
- the coating portions are kept in the folded position by a cable and released when introduced in the part already coated above and drawn using a cable to their final location.
- a wide opening remains however between the free ends of the portions coating, this opening being completed by one or several ring parts introduced separately, making thus the process impossible to carry out in a microtunnel where human intervention is not possible.
- the object of the invention is to remedy the drawbacks above and to provide a method for carrying out coated excavations, in particular microtunnels, in a simple way in convergent soils located at great depth.
- the portions introduced are tube elements cut along their length which are folded, in compression or in a stable state, so that their free ends cover each other, and which are extended to their final location, either by their own elasticity in case they were kept in compression, either by an appropriate device (for example jacks) in the other case, until they form a closed ring leaving no that a possible opening which can close later by the convergence of the soil.
- a second coating or final coating is applied at inside the tube elements.
- this second coating comprises elements which are pushed through tube elements already in square.
- the elements of the second coating can have a diameter equal, except for tolerances, to the inside diameter of the tube elements in closed end position.
- the second coating can be applied in the form of conventional tube elements which are welded together to form a waterproof coating.
- the second coating or a part thereof can be used to push the last tube elements to install through tube elements already in place.
- the figures relate to the realization of an excavation in the form of a horizontal microtunnel of diameter included between 0.5 and 1.5 m, from a main gallery already existing 16, in a clay soil 1, at great depth.
- an excavation device that is to say a microtunnelier 2 is used consisting of three stations, i.e. an anchor station 3, one pusher station 4 and an excavation station 5.
- 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 provided also hydraulic cylinders.
- the anchor station 3 is released and retracted to excavation station 5, using the cylinders pushing station hydraulics 4. Place necessary for the location of a covering element auxiliary 7 is thus released at the rear of the microtunnelier 2.
- the above procedure is repeated, in starting with a new anchoring of the microtunnelier 2.
- the covering is placed in two stages, i.e. a first stage during which a first coating or auxiliary coating 7, intended to resume during the construction of the tunnel, the ground pressures 1 (of the order of 1 MPa), is put in place and a second step during which a second coating or coating final 8, intended to take up ground pressure 1 long term (of the order of 5 MPa), is implemented.
- the auxiliary coating 7 is formed of tube elements 9, for example made of metal, with a thickness of between 5 and 10 mm, and therefore somewhat elastically deformable, which are cut along their entire length and folded over them same, as shown in Figure 2.
- These elements of tube 9 can be routed, one behind the other, in the folded position, up to their location in 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 sectioning, as shown in Figure 3, leaving thus a longitudinal opening 10.
- Each element of tube 9 is provided on its outer face at the level of the longitudinal section, of a guide 11 formed by a flange curve. The function of this guide is the subject of another paragraph.
- auxiliary covering 7 The installation of the auxiliary covering 7 is carried out from the as follows: a first tube element 9 is put in place in the microtunnel; the following tube elements 9 are previously folded back on themselves and introduced one after the other, as shown in section on the figure 2, from the main gallery 16, as and measure that microtunnelier 2 is excavating.
- the tube elements 9 are thus pushed to the level 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 Figure 3, leaving a longitudinal opening 10.
- the aforementioned guide 11 limits the movement of the walls of the tube element 9.
- each tube element 9 is such that an 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 waterproof final coating 8 is intended to take up the pressure exerted by the soil 1 in the long term.
- This final coating 8 has an equal outside diameter, at tolerances, to the inside diameter of the coating auxiliary 7 with the tube elements 9 in their position closed.
- the final coating 8 is introduced in the form of elements of tube 12 which are pushed, one after the other, to from main gallery 16, using the station 13. As they are introduced, the tube elements 12 are welded to ensure their sealing.
- the final coating 8 can be used to push towards their location the last tube elements 9.
- the microtunnel is carried out as soon as all the elements of tube 9 are in their place and that all tube elements 12 of the final covering 8 have been introduced.
- excavation need not necessarily be a horizontal microtunnel. It can be a tunnel, a gallery or any horizontal excavation or inclined or even vertical.
- the microtunnelier 2 can according to the case be replaced by another excavation device appropriate.
- the tunnel boring machine or other excavation device can build on the tube elements 9 already in place. So the station anchor 3 can be eliminated or replaced.
- the tube elements 9 of the first coating are folded back into a stable position (and are therefore no longer held in compression) and, instead of opening by their own elasticity, are mechanically extended to their final location, for example by jacks.
- tube elements 9 do not necessarily have to be made of metal. They can for example be in matters synthetic.
- tube elements 12 of the final covering 8 do not need not be metal. They can by example be concrete.
- this final coating 8 may in certain variants be omitted or replaced by concrete injection for example outside around the tube elements 9 of the auxiliary coating 7 installed.
