Description

WO2016041858

Method and installation for mechanised digging of a cross-passage between two traffic tunnels or between two vertical shafts.

FIELD OF THE INVENTION

The present invention relates to a method for mechanised digging of a cross-passage connecting two traffic tunnels or two vertical shafts in a geological environment subject to high water pressure. It also relates to an installation for its implementation, and a built structure obtained by such a method.

BACKGROUND TO THE INVENTION

Transport infrastructures increasingly often use tunnels, in particular in dense urban areas, as a response to the lack of surface space.

For reasons of transport infrastructure safety and capacity a tunnel is very often dedicated to a single traffic direction. When persons are being transported there must be emergency exits at regular intervals. The optimum spacing between two emergency exits is determined by a specific study, and is generally between 100 and 500 m.

To meet this requirement one solution consists in passing from one traffic tunnel to the other by means of what is called a "cross-passage". This expression is understood to mean a built structure linking the two tunnels.

If the infrastructure is located within the groundwater the watertightness of the built structure becomes a critical question.

The construction of watertight bored tunnels using a mechanised tunnel boring machine has now become a known problem which companies know how to manage.

However, the persistent difficulty is the construction of a cross-passage linking to previously built main tunnels. Indeed, the watertightness of these tunnels must be destroyed locally, which poses a risk of everything being flooded.

One of the traditional solutions to address this problem consists in freezing the ground in the area where the cross-passage is to be built. Freezing temporarily ensures that the ground is watertight, and can then be attacked by traditional excavation machinery.

When the coating covering the inner surface of the cross-passage is installed, and when its junctions with the main tunnels are built the entire construction is then watertight. The surrounding ground can then be unfrozen.

But freezing of ground is very sensitive to the local geotechnics. This means that the implementation details are often poorly managed, as is the associated construction cost.

For this reason more efficient construction methods are sought.

The aim of the present invention is thus to propose a method for mechanised digging of a cross-passage connecting two traffic tunnels which takes account of: the possible presence of groundwater; the fact that the start and end points of the cross-passage are tunnels which must be made watertight; the fact that the diameter of the cross-passage which is to be built is higher than the habitual values of 2000 mm, and generally of the order of 3000 mm, or higher. A similar problem is posed when creating a crosspassage between two vertical shafts.

SUMMARY OF THE INVENTION

The present invention relates firstly to a method for mechanised digging of a cross-passage between two traffic tunnels or between two vertical shafts, characterised in that it includes a series of steps in which: i/ a first segment of metal tube fitted with a drum cutter is driven forward from a first of said two tunnels or vertical shafts, in the direction of said second tunnel or shaft, where the inner diameter of this tube is equal to the inner diameter of said cross-passage; ii/ a second section of the same diameter is installed behind said first tube segment, extending it, and these two segments are driven forward together; iii/ operation ii/ is repeated as required; said tube segments are left in position and the materials contained in the tube are then removed.

With the invention, therefore, metal segments are used which, joined end-to-end, enable a large-diameter horizontal coring system to be formed, and pushed from a first tunnel in the direction of a second tunnel or, if applicable, from a first vertical shaft in the direction of a second shaft. This allows a temporary sealed lining to be installed which will be to the outer casing of the final cross-passage, without extracting the ground in place from it, whilst preventing water from entering the initial main tunnel.

The first segment of the tube is fitted with a drum cutter, preferentially with teeth. It should be noted that in the field of boring a drum cutter is a cutting tubular part installed at the end of a corer to facilitate its penetration into the ground during thrust boring.

Depending on other non-restrictive and beneficial characteristics of the invention: - step ii/ is repeated as many times as required to reach the second tunnel or vertical shaft; - alternatively, said steps i/ to iii/ are performed from each of the tunnels or vertical shafts, until the segments are joined; - prior to thrust boring step i/ a reinforcing and holding tympanum with a cylindrical aperture of diameter equal to or slightly greater than the diameter of said segments is attached to the wall of the first tunnel or vertical shaft, centred on the longitudinal axis of said cross-passage; - prior to thrust boring step i/ the steps are performed in which: - a shaft is bored along the longitudinal axis of said cross-passage, ensuring that it is watertight relative to the tunnels or vertical shafts, and a boring tube longer than said crosspassage is fitted into it, the ends of said tube protruding inside each of said tunnels or vertical shafts; - a plug is placed against the wall of each of the tunnels or vertical shafts, fitted onto each of said ends of the boring tube. This plug is inscribed in a cylinder of slightly smaller diameter than the inner diameter of said tube segments; - a means for tightening said plug against the wall of each of said tunnels or vertical shafts is placed on said ends; - said thrust boring step is implemented by means of a thrust boring device which moves said segments with a combined translational and rotational motion; - said thrust boring device is moved and guided by a pushing device attached to said tympanum; - means for centring, guiding and sealing said segments, which cooperate with the outer walls of these segments, are positioned on said pushing device; - means for centring, guiding and sealing said segments, which cooperate with the inner wall of these segments, are positioned on the periphery of said plug.

Another aspect of the invention relates to an installation for mechanised digging of a cross-passage between two traffic tunnels or between two vertical shafts, characterised in that it includes: - a set of metal tube segments including a segment fitted with a drum cutter, where the inner diameter of this tube is equal to the inner diameter of said cross-passage; a thrust boring device which moves the segments according to a combined translational and rotational motion.

Finally, another aspect of the invention relates to a built structure obtained after the digging method described above, before the materials filling the tube are removed. Said built structure includes two traffic tunnels or two vertical shafts and a tube formed from a plurality of segments extending between said traffic tunnels or between said vertical shafts, and is characterised in that the tube contains the ground separating said tunnels or vertical shafts, guaranteeing that said tunnels or shafts are watertight.

Other characteristics and benefits of the invention will come to light on reading the following description of a preferred embodiment of the invention. This description is made with reference to the appended drawings, in which: • figure 1 is a cross-sectional view of one of the two tunnels from which it is proposed to construct a cross-passage; • figure 2 is a partial longitudinal section view of said cross-passage and of a portion of the two tunnels which it enables to be connected; • figure 3 is a detailed view of part of figure 2; • finally, figure 4 is a perspective view of the above-mentioned two tunnels and of the crosspassage which joins them to one another, where the devices used to construct it are partially visible in the tunnel located at the left of the figure.

DETAILED DESCRIPTION OF THE INVENTION

In the following description and in the figures which illustrate it the creation of a cross-passage connecting two traffic tunnels is described. The invention applies, however, in a similar manner to the creation of a cross-passage between two vertical shafts .

As mentioned above, in the appended figure 1 a cross-section can be seen of one of the traffic tunnels which it is proposed to fit with a crosspassage connecting it to another tunnel (not represented in this figure). This tunnel, which may be called the first tunnel, or starting tunnel, has reference 1. This is a tunnel which has been constructed, and wall 100 of which is formed in particular from lining segments arranged in staggered rows relative to one another, in a well-known manner.

This tunnel has, in particular, a road platform 12, ventilation shafts 10, and tubes, pipes and/or cables enabling, for example, fluids or data to be conveyed. Other unrepresented equipment may be in place in the tunnel.

Second tunnel 2 is visible in particular in figure 4 .

In accordance with the invention, the cross-passage is installed without impairing the integrity of previously constructed tunnels 1 and 2, enabling additional work, delays and costs to be prevented. To this end, as will be described in detail below, a corer is used enabling the walls of the tunnels and the ground separating the two tunnels to be cut, whilst driving forward a tube defining the casing of the cross-passage, without at this stage extracting the material contained in the tube.

Before constructing the cross-passage its longitudinal axis X-X' (see figure 2) is identified using topography means known to those skilled in the art, such as a theodolite, which allows positioning relative to the metric point of the tunnel. A holding and reinforcement tympanum referenced 4 is then positioned on the side of tunnel 1. This is in fact a piece of concrete with a cylindrical aperture 40 of diameter slightly greater than that of the cross-passage which it is desired to install, which is attached against wall 100 of tunnel 1, as can be seen particularly in figures 1 and 2. The face of the tympanum facing the wall has a convex shape complementary to the concave shape of wall 100 of the tunnel. The connection between the wall of the tunnel and the tympanum must ensure local watertightness and the transfer of loads applied to the wall of the tunnel when it is cut by the corer.

Another function of this tympanum is to transfer the forces exerted on the tube 6 constituting the cross-passage, as will be seen below. A pushing device is attached to this tympanum 4 to push the corer (as an example, this pushing device includes the four horizontal, parallel rods 5 which extend inside the interior of tunnel 1) . This function will be explained below in the description. A similar tympanum can be positioned in tunnel 2.

To transmit the thrust of the immersed ground cut by the corer in tunnels 1 and 2 when cross-passage 6 is constructed, a plug 3, or respectively 3', is installed beforehand in each of tunnels 1 and 2. Each plug is intended to be pressed against wall 100, 200 of corresponding tunnel 1, 2, so as to create a robust, watertight structure while the cross-passage is driven forward.

To accomplish this a shaft C, centred on said axis, is bored along above-mentioned axis X-X', whilst guaranteeing that both tunnels are watertight. A tube T with an outer diameter slightly less than the inner diameter of shaft C is then fitted in. This tube T has the specific feature that it is substantially longer than the space separating the two tunnels 1 and 2, such that its opposite ends protrude into each tunnel.

Said plugs 3 and 3', consisting of globally cylindrical contour pieces, with a convex rear face, intended to be pressed against wall 100, or respectively 200, of the tunnels, in a watertight manner, are then put in position, by fitting them on to each of its ends.

Each of plugs 3 contains an axial through-aperture 30, 30' of diameter slightly greater than that of tube T, with an additional diameter 31 enabling a tightening part B, B' equivalent to a bolt, to be installed.

By so doing pressure forces in opposing directions are generated, which will oppose the pressure forces which will be generated when the cross-passage itself is constructed.

Otherwise said, the plugs will ensure that the materials are held in place while the cross-passage is dug, and will transmit the forces due to the thrust of any groundwater or of the surrounding ground.

Between each tympanum/plug pair there is a free annular space, which is used to construct the crosspassage .

As mentioned above in the description, the crosspassage will be constructed using tube segments 6, three of which can be seen in figure 2, with references 6a, 6b and 6c.

This is, naturally, a simple example implementation, and, depending on the length of the cross-passage, more than three segments may be used. This is why these are globally referenced 6n.

These segments, all of which are of the same diameter, are dimensioned such that they can be inserted in the annular space between each tympanum/plug pair.

To install them guidance means 32 forming a ring, the outer diameter of which is equal to the inner diameter of segments 6a to 6c, is used on the perimeter of plug 3.

Similarly, guidance means 50 in the form of a ring, which can be displaced longitudinally along rods 5, and can have an inner diameter which is very slightly greater than the outer diameter of tube segments 6, is positioned on tubes 5 forming the pushing device.

Thus, means elements 32 and 50 enable the segments to be centred and guided translationally in the direction of the space separating the tunnels, and also ensure that the segments are watertight relative to the walls of the tunnel.

The first segment installed is the one referenced 6a in figure 2. This segment is not only displaced but must also assist with the cutting of the rock and, more generally, of the ground in the volume of the future cross-passage. With this aim, the leading end of this first segment 6a is fitted with a drum cutter 60 with teeth, suitable for the ground which must be traversed.

To allow this segment to be displaced a thrust boring device, also called a "rotator", 7, which can impart a rotational motion to said segment 6a, is put in position, as shown in figure 1, enabling drum cutter 60 to cut the ground in front of it. This is combined with a translational motion imparted by pushing device 5. Segment 6a can thus move both translationally and rotationally around axis X-X'.

When this segment 6a is completely engaged inside the space between the two tunnels, withdrawal is effected, using a reverse motion of rotator 7, and a new segment 6b is put in place, and is itself displaced by the rotator, pushing first segment 6a in the direction of the second tunnel.

This operation is repeated as many times as required.

As the segments are installed each new segment is welded to the previously inserted segment, such that all these segments form a tube which is displaced with a combined rotational and translational motion around axis X-X'.

The rotator and the tube formed from the successive segments jointly form the corer mentioned above .

In the embodiment which has just been described, the segments are installed from first tunnel 1. In this case, when second tunnel 2 is approached, local freezing is for example applied, at right angles to plug 3', to drill through wall 200 of the second tunnel without impairing its watertightness.

In an unrepresented implementation one can use, in second tunnel 2, a second rotator 7 similar to the one used in entrance tunnel 1, and a tympanum similar to tympanum 4. The cross-passage then consists of two tubes driven forward from each of tunnels 1 and 2, which meet in an intermediate position. In this case the tubes are of slightly different diameters, to enable one to fit inside the other, and by this means to facilitate the connection of the two tubes.

Local freezing then enables temporary watertightness to be achieved at the point where the two tubes meet.

Thus, according to one embodiment of the invention, a method which may be used for the construction of this cross-passage can include the following steps: a) positioning in each tunnel 1 and 2 of axis X-X' of cross-passage 6; b) installation in each of tunnels 1 and 2 of a tympanum 4 strengthening the aperture of the cross-passage in the main tunnel; c) boring and installation of the system for retaining plugs 3 and 3'; d) installation of plugs 3 and 3' of each of tunnels 1 and 2; e) in first tunnel 1, installation of the guidance system of the thrust boring phase; f) in the first tunnel, installation on plug 3 of the device responsible for moving the inner face of the metal tube and ensuring that it is watertight; g) in the first tunnel, installation on tympanum 4 of the device responsible for holding the outer face of the metal tube and ensuring that it is watertight; h) in the first tunnel, installation of the translation system connecting the rotator to the tympanum; i) in the first tunnel, installation of rotator 7; j) in the first tunnel, coring of a first segment 6a of the metal tube fitted with its drum cutter (it starts by cutting the lining of the main tunnel before penetrating the ground); k) in the first tunnel, after coring of the first metal tube segment, blocking of the metal tube, removal of the rotator, insertion of the next segment, coupling with the previous segment, and resumption of coring; and so on until the tube introduced by second tunnel 2 is met; l) local freezing to ensure the watertightness of the junction.

In a particularly advantageous manner the method, as a consequence of the fact that it does not encroach upon the entire section of the main tunnels, can be implemented simultaneously with the digging of the main tunnels using mechanised tunnel boring machines.

The tube segments which constitute cross-passage 6 are "lost", since they are left in place inside the cross-passage. The ground and materials inside it are subsequently removed from the cross-passage, and lining segments are pinned on to the tube to improve the mechanical properties and watertightness of the crosspassage .

Finally, as previously described above, the invention is not limited to the creation of a crosspassage connecting two tunnels (where said tunnels extend in a roughly horizontal plane), but applies in a similar manner to the creation of a cross-passage connecting two vertical shafts.

The term "vertical shaft" is understood to mean a physical functional cavity bored vertically and connecting two different levels of depth, in particular in the tunnelling field. For example, this may relate to an access, safety or ventilation shaft.
