Definitions
- the present invention relates to a method of mechanically digging a communication branch connecting two traffic tunnels or two vertical wells in a geological environment subjected to a high water pressure. It also relates to an installation for its implementation, as well as a work obtained by such a method.
- Transport infrastructures are increasingly resorting to tunnels, especially in dense urban areas to compensate for the lack of space on the surface.
- a tunnel is very often dedicated to a single direction of traffic.
- emergency exits shall be accessible at regular intervals.
- the optimal spacing between two emergency exits results from a specific study, and is generally between 100 and 500 m.
- one solution is to go from one traffic tunnel to another by means of what is called "communication branch".
- communication branch By this expression is meant a communication structure linking the two tunnels.
- the purpose of the present invention is to propose a method of mechanically digging a communication branch connecting two traffic tunnels while taking into account: the possible presence of an underground water table; the fact that the points of departure and arrival of the branch are tunnels whose sealing must be preserved; the diameter of the communication branch to be made is greater than the usual values of 2000 mm, and rather of the order of 3000 mm or more.
- the present invention relates in the first place to a method of mechanically digging a communication branch between two traffic tunnels or between two vertical wells, characterized in that it comprises a series of steps according to which:
- metal sections are used which, abutting one after the other, make it possible to form a large diameter horizontal coring device, and to darken it from a first tunnel towards a second tunnel or, where appropriate, a first well in the direction of a second well.
- the first section of the tube is equipped with a cutting kit preferably provided with teeth. It should be recalled that in the field of drilling a cutting kit is a tubular cutting piece mounted at the end of a corer to facilitate its penetration into the ground during a sinking.
- step ii is repeated as many times as is necessary to reach the second tunnel or well;
- steps i / to iii / are implemented from each of the tunnels or wells, until said sections meet;
- step i / sinking prior to step i / sinking, is fixed against the wall of the first tunnel or well, centered on the longitudinal axis of said branch, a tympanum of reinforcement and holding which has a cylindrical opening of diameter equal to or slightly greater than diameter of said sections;
- said driving step is implemented by means of a sinking device which moves said sections in a combined movement of translation and rotation;
- said driving device is moved and guided by a stuffing device fixed on said tympanum;
- Another aspect of the invention relates to a mechanized digging plant for a communication branch between two traffic tunnels or between two vertical wells, characterized in that it comprises:
- a set of sections of metal tube including a section provided with a cutting kit, the internal diameter of this tube being equal to the internal diameter of said communication branch;
- a sinking device which moves said sections in a combined movement of translation and rotation.
- Said structure comprises two circulation tunnels or two vertical wells and a tube formed of a plurality of sections extending between said tunnels or between said wells and is characterized in that said tube contains the floor separating said tunnels or wells. guaranteeing tightness with respect to said tunnels or wells.
- Figure 1 is a cross-sectional view of one of the two tunnels from which it is proposed to build a communication branch;
- Figure 2 is a partial longitudinal sectional view of said communication branch and a portion of the two tunnels that can be connected;
- Figure 3 is a detail view of a portion of Figure 2;
- Figure 4 is a perspective view of the two aforementioned tunnels and the communication branch which makes them join, the devices used for its realization being partially visible in the tunnel to the left of the figure.
- This tunnel is equipped in particular with a platform 12 of circulation, ventilation ducts 10, as well as tubes, pipes and / or cables allowing for example the circulation of fluids or information. Other equipment not shown may be in place in the tunnel.
- the second tunnel 2 is particularly visible in FIG.
- the establishment of the communication branch is carried out without compromising the integrity of tunnels 1 and 2 already built, which makes it possible to avoid generating work, delays and additional costs.
- a corer for cutting the tunnel wall and the floor separating the two tunnels while driving a tube defining the envelope of the branch, without extracting it. stage the materials contained in the tube.
- a retention and reinforcing eardrum referenced 4 is positioned on the side of the first tunnel 1. It is in fact a concrete part which has a cylindrical opening 40 of diameter slightly greater than that of the branch that the it is desired to put in place, which is fixed against the wall 100 of the tunnel 1, as is particularly visible in Figures 1 and 2.
- the face of the tympanum facing the wall has a convex shape complementary to the concave shape of the wall 100 of the tunnel. The connection between the tunnel wall and the tympanum must ensure local sealing and load transfer applied to the tunnel wall when pierced by the corer.
- this eardrum is also to ensure the recovery of the forces exerted on the tube 6 constituting the branch, as will be seen below.
- this pushing device for pushing the corer (for example this pushing device comprises the four horizontal and parallel rods 5 which extend towards the inside of the tunnel 1). This function will be explained later in the description.
- a similar eardrum can be placed in the tunnel 2.
- a plug 3 respectively 3 '.
- Each of these plugs is intended to bear against the wall 100, 200 of the corresponding tunnel 1, 2, so as to create a solid and sealed structure when sinking the branch.
- said plug 3, 3 ' which consists of a generally cylindrical contour piece, with a convex rear face, intended to be pressed against the wall 100, respectively 200 tunnels , this in a sealed manner.
- Each of the plugs 3 has an axial through opening 30, 30 'of diameter slightly greater than that of the tube T with an increase in diameter 31 which allows to set up a clamping piece B, B' similar to a bolt.
- the plugs will ensure the holding of the materials during the digging of the branch and resume the efforts due to outbreaks of groundwater and the surrounding soil.
- each couple eardrum / cap there is a free annular space, which is used for the realization of the branch.
- These sections are dimensioned so that they can be inserted into the annular space present between each tympanic / plug pair.
- the outer diameter is equal to the inner diameter of the sections 6a to 6c.
- a crown-shaped guide means 50 is positioned, which has the capacity to be displaced longitudinally along the rods 5 and to have an inside diameter that is very slightly greater than the diameter. outside the pipe sections 6.
- the elements 32 and 50 make it possible to ensure a centering and a guide in translation of the sections in the direction of the space separating the tunnels, as well as the sealing of the sections vis-à-vis the walls of the tunnel.
- the first section set up is that which is referenced 6a in Figure 2. This section is not only moved but must also contribute to the cutting of the rock and, more generally, the soil occupying the volume of the future branch.
- the upstream end of this first section 6a is provided with a cutting kit 60 provided with teeth adapted to the terrain to be crossed.
- a driving device also called “rotator” 7 is positioned as shown in FIG. 7, which has the capacity to impart a rotational movement to said section 6a, allowing the cutting tool 60 to cut the field in front of her. To this is combined a translational movement provided by the pushing device 5.
- the section 6a can therefore move both in translation and in rotation around the axis X-X '.
- each new section is welded to the section previously inserted, so that all of these sections form a tube that moves in the same combined movement of rotation and translation around the X-X 'axis.
- the rotator and the tube formed successive sections together form the corer mentioned above.
- the implementation of the sections is done from the first tunnel 1.
- local freezing is performed at the right of the plug 3 'to pierce the wall 200 of the second tunnel without altering the seal.
- a second rotator 7 similar to that which equips the input tunnel 1 and a
- the communication branch is then composed of two dark tubes from each tunnel 1 and 2, which meet in an intermediate position.
- the tubes are of slightly different diameters to allow penetration of one into the other and thus facilitate the connection of the two tubes.
- a method that can be implemented for the realization of this branch may comprise the following steps:
- first tunnel side placing on the plug 3 of the device ensuring the movement and sealing on the inner face of the metal tube
- first tunnel side placing on the eardrum 4 of the device ensuring the maintenance and sealing of the outer face of the metal tube
- the method because it does not encroach on the entire section of the main tunnels, can be set up in parallel with the digging of the main tunnels by means of mechanized tunnel boring machines.
- the sections of tube that constitute the branch 6 are "lost", because they are left in place inside the branch. This one is later free of soil and materials clogging it, and plate on the tube of voussoirs to complete the mechanical strength and tightness of the branch.
- the invention is not limited to the creation of a communication branch connecting two tunnels (said tunnels extending in a substantially horizontal plane) but applies in a manner similar to the creation a communication branch connecting two vertical wells.
- Vertical well means a physical functional cavity drilled vertically and connecting two levels of different depth, particularly in the field of tunnels.
- it may be an access, security or ventilation shaft.
