APPARATUS FOR CARRYING OUT THE SHIELD METHOD OF TUNNEL AND GALLERY CONSTRUCTION
This invention relates to an apparatus for carrying out the shield method of tunnel and gallery construction consisting of a steel cylinder with a slicing taper on its end face, the cylinder being offset near its end face in order to form a collar preferably extending over the entire periphery of the cylinder.
A known apparatus for carrying out the shield metho tunnel or gallery construction consists cf a steel cylin< with a slicing taper on its end face, in which the cylin-is offset near its end face to form a collar and in the region of this collar tubes are provided for the dischar of concrete. In order to advance the shield, concrete i forced through the tubes, and for facilitating the forw movement and for the consolidation of the concrete jolt-ramming machines are employed which act directly on the front parts of the shield carrying the slicing taper. Ar appliance of this type has not as yet been practically possible and has not therefore found any application in practice. Research carried out by the present applicant shows that the pressure necessary for the advance of the shield and to be applied to the plastic concrete is so high that the concrete would continuously consolidate in the feed tubes and would finally set there, which of course is intolerable for a rational mode of operation. Further devices are known which are employed in non-comps soils (moraines, sand, earth, etc.). They consist of a steel cylinder open at two ends which has at the rear a thrust ring against which are supported a plurality of preferably double-acting hydraulic rams arranged on the inside of the steel cylinder. The end face of the steel
cylinder, situated in the direction of forward movement, is made of cutter sections. In the interior of the steel cylinder there are mounted mining appliances and also conveying devices for removing the spoil. For the
utilisation of this device 'a trench is dug into which the steel cylinder is lowered. By being supported against an abutment in this trench, the device is moved forward hydraulically in the advance direction, the zone covered in each case by the forward movement is fully concreted immediately afterwards or possibly clad with prefabricated concrete facing. These known devices are very expensive, and, since they consist of a peripherally-closed cylinder they can be disassembled only with great difficulty inside a tunnel tube or gallery and the very expensive hydraulic cylinders, which are provided inside the tube in large number, are constantly exposed to the danger of the falling debris and it is only possible to produce a comparatively slight advance pressure, limited by the possible piston surface area. All these are considerable and serious disadvantages, which it is the object and purpose, of the present invention to obviate.
In accordance with the invention this is achieved in that there is provided on the collar surface, formed by the offsetting of the cylinder, at least one flexible bag-type bellows which can be acted on by a pressure medium (oil, water, air or the like), and the tubes for the discharge of concrete towards the exterior are located near the bellows, preferably these tube apertures are situated in the tapered generated surface formed by the offsetting of the cylinder. The subject matter of the invention
represents a substantial step forward in relation to the known constructions, since with this it is possible to operate on the lines of a two-cycle process, that is to say alternate advance and admission of the concrete.
A specific embodiment of the invention will now be described in detail by way of example with reference to the accompanying drawings, in which:
Figure 1 shows a longitudinal section through a steel cylinder, taken along the line A-A in Figure 3, which in the following will be designated as the driving shield,
Figure 2 shows a longitudinal section taken along the line B-B in Figure 3,
Figure 3 shows a cross-section taken along the line C-in Figure 1 , and
Figures 4 and 5 shows details of the collar.
A driving shield 1 consists of a steel cylinder which has on its end face 3 a slicing taper 4. The diameter of the steel cylinder corresponds to the diameter of the gallery or tunnel to be made. Near its end face 3 the steel cylinder is offset so as to form a collar 5, in the vicinity of which tubes 6 discharge in outward direction (Figure 4). The tubes 6 are spaced along the periphery of the rotating collar 5 as uniformly as possible as shown in Figure 3 and are situated in groove-like recesses 6' (these recesses do not appear in Figures
1 and 2 for the sake of clarity ) , which can be formed by welded ribs or which can be cast with the cylinder.
The mouth zones of the tubes 6 are widened in trumpet- themselves
like manner and the apertures 7 &e»&l-ew« are situated near the collar surface 5' formed by the offsetting of the
cylinder. The collar surface 5' is provided with troughlike recesses 8 (Figure 5) in which there lie bag-type bellows 9 of flexible material such as rubber, which bellows can be acted on, by way of aseeesfied tubes 10, by a suitable pressure medium (oil, water, air). The recesses and bellows are distributed as evenly as possible along
the periphery of the rotating collar 5 or collar surface 5', respectively, (see Figure >} . In the material of the bellows it is possible for springs or spring sets to be incorporated, which springs hold the released bellows
9 in the position evident in Figure 5, or after relieving of the bellows return again to this shape.
Viewed in peripheral direction the steel cylinder 2 is in multipart form being made up of a number of lower segments 2', and an upper segment 1 !. The segment 11 has outwardly diverging boundary surfaces or flanges 12. The outer generated surface 1 of the driving shield 1 exhibits a slightly conical path in which it tapers
towards the rear. At the rearward end 1 of the driving shield there is attached a relatively thin—walled tubular fitting 15· As evident in particular in Figure 4, a second tube 20 discharges into the aperture of each tube 6, this tube 20 extending arcuately at its front end and moreover for its protection it is situated in the groovelike recess 6'. The arcuate course is thus so formed that the flow forcibly caused thereby is directed towards the longitudinal axis of the tube 6, as indicated by the arrow 21 in Figure 4.
The mode of operation of the illustrated driving shield can be seen directly from the drawing and will be
explained in the following in all necessary details, the initial structural condition of the tunnel tube or lining 16 being as shown in Figure 1. Concrete is admitted via the tubes 6 into the hollov/ annular chamber formed by the collar 5 and the conically extending surface 13 of the driving shield by means of concrete pumps which are not shown but are sufficiently well known. Then the tubes 20 are charged with compressed air or water so that due to the arcuate curvature in the outlet zone of these tubes 20 the tubes 6 are blown through rearwards against the direction of admission of the concrete, as the arrow 21 indicates, while the forward movement is interrupted, so that the tubes 6 and 20 can be rinsed fre of concrete. When the concrete has been admitted and has hardened, the bellows 9 are acted on via the pipes 10 by means of a suitable pressure medium under high pressur By means of the force of reaction of the large bellows areas the driving shield is forced ahead under great pressure into the ground material 18, in this way the latter collapses by itself or can be excavated by means of cutting and mining units, conventional excavators and loading appliances carried in the steel cylinder and subsequently conveyed away. Owing to the enforced advanc which is dependent on the material to be excavated and or_ the expansibility of the bellows 9, an annular space is cleared which is bounded by the collar surface 5', by the region (immediately following the collar) of the surfa 13 and of the end face of the previously cast concrete lining 16, and by the earth 18. The bellows 9 are relieved and simultaneously concrete is forced via the
tubes 6 into this annular space, while the concrete lying in the mouthpiece 6 and which is not rinsed out and possibly hardened, is expelled and exhausted because of the trumpet- shaped design of this tube section 6. When the concrete has been forced into the annular space, then the above-described process is repeated once more. In this way it is possible to provide galleries or tunnels with a homogenous monolithic concrete lining purely as a shell, without the danger arising that the earth loosened by the advance of the shield collapses or caves in and endangers machines and apparatus. It is because of this danger, in the case of all conventional methods, that a gallery construction of this type is jeopardized to a large extent.
A bellows arrangement with a specific bellows load
of 500kg/cm , which lies completely within the normal
range, and used with a shield having a diameter of about
8.4 m. enables an advance pressure of 42,000 metric tons to be achieved, that is to say a value which lies far
above any value which can be obtained with other appliances of this type.
Besides monolithic concrete linings it is possible
of course in tectonically moved ground zones for articulate pipes to be concreted in similarly simple manner, in that after specific and freely excavatable advance distances, packing materials are forced into the annular space,
which is cleared in each case by the forward movement,
through apertures 25 (Figure 5) situated in the vicinity of the collar 5 and only after renewed forward movement
is concrete then forced in. In order to overcome the
high degree of friction on the cylinder 2, after long
rest periods, caused by shrinking of the tunnel lining during setting, high frequency jolt-ramming elements are advantai?;eously provided inside the shield 2.
Owing to the trough-like recesses these individual successive sections of concrete lining are in this case joined together by teeth. Pump units for forcing the concrete packing material and the pressure medium for the bellows 9 and also mining and conveying appliances can be accommodated in the cylinder 15.
Since several bellows are provided over the entire periphery of the collar 5, they can be acted on by
corresponding control devices with different pressures in each case, so that the driving shield can be driven forward not only in axial direction, that is, straight, but can also be controlled as desired, so that the driving shield can be guided upwards or downwards or to one side or the other. In addition by means of the varied action of the bellows 9 it is possible to allow for unequal
resistance of the material to excavation.
Since the driving shield is of multipart form,
when viewed in peripheral direction, it is also possible to produce with the apparatus blind galleries or blind tunnels, such as are necessary in connection with underground railways. When the planned and proposed end section
of such a blind gallery is reached, then the driving
shield can be disassembled within the gallery itself
and its individual components can be conveyed away
through the gallery. By means of the arrangements
according to the invention all appropriate building
projects can be carried out extremely rapidly and
inexpensively. In this way conventional traffic schemes, for example, underground railway constructions, can be influenced very positively, since the underground borings can be effected without regard to building obstacles at the surface in cities or of the composition of the surface, such as canals, rivers, supplies lines etc. A loop-line underground railway system can be built with continuous traffic in both directions. The connecting shafts from the tunnel lining to the surface need only be dug down into the tunnel lining after positions have been measured beforehand to avoid the zones where joints occur, the tunnel lining section being exploded without the tunnel mouth on either side undergoing any damage or being
subjected to any reduction of static strength.
The end parts of the steel cylinder can consist of individual cutting segments 4' (see Figures 1 and 2), which are detachably fastened with cutters, so that
these cutting devices can be easily adapted to the
material to be excavated. It is also possible to offset in saw-tooth manner the slicing taper at xhe end face of the steel cylinder, as shown diagrammatically by the broken line 30 in Figure 2. It is also possible to provide, in the space recessed in the shield, sighting mechanisms so that the direction of advance can be continuously checked and supervised.
It is also easily possible to carry out reinforcing of the concrete lining or of individual sections of
lining by providing near the collar 5, preferably in
the region of the cross-sectional plane formed by the apertures 25, further apertures 26 in the cylinder, through
which steel reinforcing components are inserted after each advance and before or during the introduction of the concrete. The steel reinforcing components can he
practically endless so that the concrete lining or portions of it are strengthened by encircling reinforcing spirals.
In order to achieve rapid setting of the concrete the pipes 6 can be heated. For this purpose it is also possible to incorporate aggregates; in this case the already mixed concrete can be fed through the pipes 6, however it is also possible to supply the dry concrete "iix through the pipes 6 and to add the mixing water, if necessary with additives, only in the region of the
aperture 7, for which purpose it is advantageous to
provide a further pipe line (besides the pipe 26 -Figure 4) which can likewise be heated, so that heated mixing water is to be added to the dry concrete mix.
In the preceding a driving shield with a circular periphery has been described and illustrated. It is of course within the scope of the invention to give to the driving shield an outline other than circular, for example to make this shield elliptical or oval in cross-section.
Even in water-laden substances xhe apparatus described can be used with advantage. If water breaks in then concrete is injected in near the end face of the driving shield to form a partition filling up the cross-sectional space of same, which partition is pushed rearwards during the successive advance of the shield by the bellows 9 together with the excavated ma.terial, so that in this way a bulkhead-type seal is produced.
The proposed apparatus can be used for all underground
projects and is practically unlimited as regards its diameter. According to the collar thickness chosen it is possible to obtain different concrete tube outer linings. There are no restrictions as regards the composition of the ground for the use of the apparatus according to the invention, since it is possible to traverse even rock and slate
strata, while of course when used in solid rock, excavations in the gallery front wall by means of blasting are necessary. Neither the driving shield nor the already concreted gallery wall are damaged by the shocks which occur. In order to protect the pump units and measuring devices, which are arranged only at the rear end of the driving shield and therefore in the region of the cylinder 1 5 , strong shock chains and a strong rubber apron are suspended from the top, preferably in the vicinity of the joint separating the cylinder 2 and the cylinder 1 5 . Two thirds of the
cross-section of the tube from the top downwards are
always free for the passage of mining appliances and
excavators. The entire casing is thus so arranged and
constructed that no damage can arise because of the
forward movement, the explosions or the passing of
heavy mining equipment or excavators, since these tubes all lie in channel-like recesses which are either
manufactured simultaneously when the steel cylinder is
cast or which can be produced subsequently by attaching ribs.
It should also be mentioned that in the region of
the cross-sectional plane formed by the apertures 25 and
26 it is possible to provide apertures inclined obliquely forward, through which consolidation probes can be inserted.
The axis of such an aperture is indicated by the dash-dot line 27 in Figure 5.
The apparatus proposed is simple in its construction and mod.e of operation, it can be used to advantage with any ground composition, it enables the production of continuous monolithic or articiulate concrete linings, either reinforced or unreinforced and can be used not only in the production of continuous gal?_eries and tunnels but also blind ones. Apart from this the pressure required fo"r the forward movement can be chosen many times greater than that in respect of the known devices, which enables the apparatus according to the invention to be used even in solid rock-like material.
