METHOD AND APPARATUS FOR USE IN TUNNELLING BACKGROUND OF THE INVENTION This invention relates to a method and apparatus for use in tunnelling.
Ever since the creation of large-section underground tunnels and galleries in non-rocky terrain, the drilling of the terrain has taken place generally over relatively short lengths and has been immediately followed by the installation of supporting means to prevent falls of earth. In the case of sufficiently compact terrain support can be achieved by timbering or by placing buttresses and arches or metal props, as is generally the case in mining galleries. On the other hand, if the terrain is liable to crumble, alluvial terrain for example, it is provided before drilling with the desired compactness by injecting chemical filling, most often on a silica gel base or made of synthetic resin. Apart from the ever present possibility of the danger of falls of earth during the course of the injection procedure or before the filling substances sets, the cost of excavation is very considerably increased.
SUMMARY OF THE INVENTION According to the present invention there is provided a method of tunnelling comprising supporting the terrain with an annular fluid mass under pressure, advancing the fluid mass, and introducing lining compound, allowing the lining compound to set in the form of a tube, and internally coating the tube over a length substantially equal to that of the lining compound which has been introduced.
According to a further aspect of the present invention there is provided apparatus for use in tunnelling comprising a tube whose external diameter is substantially equal to the internal diameter of a lining compound support and connected to a shield of the apparatus, a flexible wall joined to the external wall of the tube in the neighborhood of its leading edge and a portion of the tube intermediate its ends to define a pocket between the tube and the flexible wall at least one conduit for injecting lining compound on the outer side of the flexible wall of the pocket and a pipe for introducing fluid under pressure into the inside of the pocket.
The tube can be of a uniform thickness or can have at the front a short shoulder, an inflatable wall integral with this shoulder and with the trailing edge of this tube and a means for introducing fluid under pressure into this inflatable wall.
REFERENCE TO THE DRAWINGS The invention will now be described in more detail, by way of example only, with reference to the accompanying diagrammatic drawings, in which:
FIG. 1 is a partial vertical section of apparatus for supporting a tunnel under construction before the injection of a lining compound;
FIG. 2 shows the apparatus of FIG. 1 after injection of the lining compound;
FIG. 3 is a partiial vertical section of a second form of apparatus for supporting a tunnel under construction before the injection of a lining compound;
FIG. 4 shows the device in FIG. 3 after the injection of the lining compound;
FIG. 5 is a partial vertical section of a third form of apparatus for supporting a tunnel under construction after the injection of a lining compound; and
FIG. 6 is a partial vertical section of a fourth form of apparatus for supporting a tunnel under construction.
In the drawings like parts are designated similar reference numerals, letter subscripts being employed to distinguish between the various embodiments.
DESCRIPTION OF THE PREFERRED EMBODIMENTS substantially constant thickness, whose external diame- 0 ter is substantially equal to the internal diameter d) of a dry lining compound 2, which may be mortar or grout, for supporting the terrain 3. An inflatable pocket 4 is mounted over the greater part of the tube 1, and is integral with the leading edge 5 of the tube 1 and with a zone 6 disposed at a short distance from its trailing edge 7. A pipe 8 opening through tube 1 makes it possible to connect the internal volume of the pocket 4 with a source of compressed air. A conduit 9 opening above the external wall of the pocket 4 is used for the injection of fresh lining compound. The tube 1, pocket 4 and conduit 9 are integral with the shield 10.
The apparatus operates as follows:
The shield 10 is advanced to leave a space e between the rear end 7 of the tube 1 and a lining ring 11 previously put in place, space e having a length equal to that of the ring 11. During the advance of the shield 10, the pocket 4 is kept under pressure to follow both the shape of the terrain 3 and that of the dry lining compound 2. Fresh lining compound is then injected via the conduit 9 which flows between the terrain 3 and the pocket 4 to reach the point 13 as it cannot flow in front of the pocket 4 which is integral with a rigid ring 12. The injection ceases when the length of the fresh lining compound which has been injected in to point 13 is practically equal to the distance e. While drying the fresh lining compound sets on the face 14 of the dry lining compound 2. While the lining compound is being injected and is setting, a sealing layer 15, for example epoxy resin and tar, is applied on the internal surface of the dry lining compound 2. A new ring 16 (FIG. 2) is then put in place using jacks 17 to support the arch stones of ring 16 on ring 11, in the normal way, the arch stones being keyed on the jacks. I
The method of providing support as described above ensures a continuous means of supporting the terrain without the risk of earth falls and without necessitating, in the case of alluvial terrain, any prior expensive injection into the mass in order to ensure that the terrain is compact. Injections over a very limited thickness around the cutting elements of the shield can however be useful in facilitating the insertion of the annular lining compound without causing the terrain to break up.
The apparatus in FIGS. 3 and 4 differs from that in FIGS. 1 and 2 only by internal tube la. Tube 1a has a short external shoulder 18 at the front and over the remainder of tube la is fixed a second inflatable wall 19.
A pipe 20 provides a-connection of chamber 211 to a source of compressed air. This apparatus can be used for minimizing the risks of the tube and the inflatable wall 40 adhering to the newly injected filling of grout or mortar when the shield advances.
The apparatus shown in FIG. can be used in the case of continuous advance for drilling. The apparatus differs from that in FIGS. 1 and 2 only by internal tube lb. The tube lb has a rear portion 22 the length of which is greater than the length e of the lining rings and is shaped as an external shoulder in order to take up the thickness of the inflatable wall 4b.
With this apparatus, the advance of boring is fixed at the length e for the duration of setting of a length e of injected lining compound. In the position shown in this figure the zone A corresponds to the n" ring which has been assembled, the zone B to the start of the mounting of the (n l)" ring. In the dry lining compound the zone C corresponds to the lining compound which is in the process of setting and the zone D to fresh lining compound, all these zones having a length e. In this case too, as in the case of FIGS. 1 to 4, the support of the terrain is continuous because of the action of the compound which is supported when fresh and during setting by skirt 22 and by annular chamber 23 filled with compressed air.
In order to facilitate the mounting, dismounting and exchange of flexible walls, the inflatable wall is made preferably as shown in FIG. 6. The compression chamber 23c for the terrain is defined externally by the inflatable wall 4c and on the inside by a sheet of rubber 25 resting on internal tube and on inflatable tubes 26. Tubes 26 and sheet 25 replace the second inflatable sheet 19 of FIGS. 3 and 4 and in addition the sheet 25 guarantees the internal tightness of the compression chamber 23c. Between the inflatable wall 4c and the sheet 25 there is interposed on the side of the ring 12c a chamber 27 defined by a flexible wall 24. The two edges 28 and 29 of the wall 24, the inflatable wall 4c and the sheet 25 are fixed on the ring 12c by means of the steel arch members constituting the tube 1c.
During assembly, the chamber 27 is flattened which facilitates the insertion of the inflatable wall 40. Chamber 27 is then filled with non-compressible fluid, generally water, so as to force the inflatable 'wall against the ring 12c which to this end has a frusto-conical shape widening towards the rear as shown in the figure. The inflatable tubes 26 are filled with either compressed air or advantageously water.
The method and apparatus for providing support as described can be used when working galleries, tunnels, pits and the like.
