Definitions
- the present invention relates to a method and a device for drilling in a subsurface, more particularly for drilling a tunnel in a ground.
- a shield ground material is excavated using a cutting wheel on the end of a steel tube, referred to as a shield, which ground material is transported above the ground surface using a liquid.
- the shield connects onto the already manufactured part of the tunnel wall, which is built up of successively placed rings, wherein one additional ring at a time is added to the tunnel wall per predetermined displacement of the shield.
- the progress of the shield with the cutting wheel placed therein is effected by thrusting the shield against the tunnel wall using a number of pressure jacks.
- Such tunnel boring machines are controlled for the most part manually by a driver or operator trained for this purpose.
- the operator can control the drilling process using a number of control parameters, including the rotation speed of the drill, the degree of thrust of each of the pressure jacks, the discharge speed of the dislodged ground material and so on.
- a drawback of such tunnel boring machines is that deformations may occur on the surface of the subsurface, i.e. displacements of the subsurface in both horizontal and vertical direction, which may cause serious damage to the infrastructure and the buildings on the surface.
- the operator adjusts the control parameters of the drilling machine on the basis of his training and experience.
- the operator can also make use here of theoretically defined control parameters calculated using for instance a finite element model of the ground and the drilling machine on the basis of the measured deformations and ground parameters representative of the properties of the ground .

- Such a manner of operation is preferably parameterized in a number of control parameters.
- an optimal manner of operating the drilling means is determined which may or may not be modified. This determination of the manner of operating takes place substantially in real-time, so that more or less direct relationships can
- a further advantage of the method according to the invention is that the manner of operating is o essentially independent of the structure of the ground and independent of the noise in the measurement data used. The changes of the ground in time or the distance covered are moreover included in the measurement data itself .
- control parameter determining means such as expert systems, which incorporate knowledge and o experience of the relations between deformation data and control parameters .
- expert systems can comprise a large number of "rules" or fixed relationships with which the correct control parameters are determined.
- 5 expert system comprises a neural network in which the relations between the deformation data, status data and control parameters can be determined. According to a preferred embodiment of the invention the method therefore comprises of :

- step e of the method comprises of inputting the deformation data and status data into a neural o network and outputting the control parameters determined with the neural network.
- the output of the neural network provides the operator with a number of control parameters for controlling the drilling means. The operator may or may not make use hereof in controlling the tunnel boring s machine .
- the steps of determining the deformation data and inputting deformation data into a neural network are preferably repeated so often that the neural network is trained on the basis of the status data, the inputted o deformation data and the control parameters ultimately chosen by the operator for controlling the drilling means. It is hereby possible for instance to transfer the knowledge and experience of the operator to the neural network.
- the neural network is trained beforehand, for instance during drilling of an earlier tunnel or conduit, so that training of the neural network can be dispensed with during drilling of a subsequent tunnel or conduit.
- the method comprises of showing an operator one or more of the determined control parameters .

- a well-trained neural network can produce a better drilling performance than an operator.
- the method comprises of comparing the predetermined manner of operating (step a) with the manner of operating the drilling means determined in step e and, subject to the result of the comparison, choosing a preferred manner of operating the drilling means.
- the comparison comprises for instance of determining the difference between the control parameters. If the difference is greater than a predetermined value, the operator is for instance informed thereof by means of an acoustic or optical warning signal .
- the method comprises of repeating the steps a to e per predetermined drilling distance, which preferably corresponds with the length of the above mentioned rings of the tunnel wall .
- the starting point is the predetermined starting value of the control parameters, which may or may not then be adjusted on the basis of the results of the calculations using the neural network.
- the method comprises of adding to the neural network analytically predetermined limit values for predicting unstable situations, whereby such situations can be avoided in improved manner.
- control parameters used during the drilling of a first tunnel or conduit are stored, for instance in a database, while during drilling of a second tunnel these control parameters are retrieved and compared with the control parameters determined for drilling the second tunnel or conduit .
- Use can hereby be made of the experience acquired in drilling the first tunnel, whereby the risk of deformations and the like can be further reduced.

- the method comprises of simulating the drilling of the tunnel or conduit in the subsurface on the basis of a physical model of inter alia the subsurface and of the drilling means. Rather than performing actual drilling, the drilling is simulated in this embodiment using the physical model . Such a simulation is preferably performed for the purpose of training an operator, who can hereby gain experience without any danger of damage occurring. Such simulations can moreover be performed in advance, i.e. before drilling, to enable the drilling to be optimized.
- the method comprises of testing one or more components of the drilling means by simulating the drilling. At least one component can hereby be tested in a factory or on-site without an expensive test drilling being required for this purpose.

- FIG. 1 shows a schematic view in perspective of a tunnel boring machine which is drilling a tunnel beneath two buildings;
- - figure 2 shows an enlarged view of the preferred embodiment of figure 1
- - figure 3 shows a diagram giving a schematic explanation of the operation of the embodiment of fig. 1.
- a trench can be excavated in the subsurface, in which tunnel segments are arranged, whereafter the trench may or may not be covered again.
- Such a technique can be applied both on land and under water.
- the cost of constructing a tunnel in accordance with such a technique is relatively low.
- a drawback of this known technique is however that it cannot be applied, or only with great difficultly, in densely built-up areas. It is moreover hardly socially acceptable in particular cases to construct such tunnels in nature reserves, areas of particular cultural- historical nature or similar areas.
- a further drawback is that when such a tunnel is constructed in such a case the existing infrastructure of roads, and lines for water, electricity and communication etc. have to be adapted for a longer period, which may result in high indirect costs.
- TBM tunnel boring machine 1
- Such a tunnel boring machine 1 is shown in figure 1.
- a tunnel is being dug in a ground B using tunnel boring machine 1.
- the already completed part of the tunnel wall consists of a number of successively placed concrete tunnel wall rings R.
- a steel tube or shield 6 is provided, this shield being shown in more detail in figure 2 and having dimensions which are slightly larger than those of the tunnel wall rings R, so that shield 6 is shifted some distance over the last tunnel wall rings of the tunnel wall (fig. 2) .
- a rotatable cutting wheel 2 is provided at the drilling end of shield 6.
- the cutting wheel 2 is set into rotation (to the left or the right) by an (electric) drive motor 3 arranged on shield 6.
- the cutting wheel 2 dislodges the ground material from the ground B as it rotates, wherein shield 6 is simultaneously pushed forward in a translating movement in the direction of arrow A. This pushing takes place by means of a number of pressure jacks 5 arranged between shield 6 and the last tunnel wall ring R.
- Pressure jacks 5 are herein distributed evenly over the end surface of tunnel wall ring R.
- Each tunnel wall ring R is built up of a number of, for instance seven, segments S.
- said pressure jacks 5 When a tunnel wall ring R is mounted, said pressure jacks 5 must be retracted pairwise to leave space for the segment S for placing.
- a new tunnel wall ring R is arranged in each case against the last tunnel wall ring by successively arranging new tunnel wall segments S, whereby the length of the tunnel is increased in steps of one tunnel wall ring .
- the ground material b dislodged during excavation is discharged as follows in the shown embodiment .
- bentonite liquid is supplied to a space between the cutting wheel 2 and a pressure bulkhead 14 placed therebehind of shield 6.
- the dislodged ground material b also ends up in this space.
- the bentonite liquid mixes with the dislodged ground material and the s mixture is discharged via a suction nozzle 13 and a discharge conduit (not shown) to a location above the ground surface.
- safety wall 15 has an opening on the underside so that the dislodged ground material can be drawn off via suction nozzle 13. In the case of o maintenance work however, safety wall 15 can be closed and maintenance staff can enter the space between pressure bulkhead 14 and safety wall 15 via air lock 16.
- the tunnel boring machine 1 also comprises one or more displaceable trailers 7 on which a supply of tunnel 5 segments S are supported. Further arranged on trailers 7 are a number of pumps, for instance for supplying bentonite liquid respectively discharging the mixture of bentonite liquid and dislodged ground material via a number of feed and drain conduits.
- a tail seal 10 Between the end of the shield 6 extending over the tunnel wall on the one hand and the tunnel wall on the other there is provided a tail seal 10, in which a feed mechanism 19 for feeding a grout mixture can be arranged.
- the feed mechanism serves to spray grout material into the space created around the tunnel wall during drilling, this because the outer diameter of shield 6 is larger than the outer diameter of the tunnel wall, and because in many cases the shield 6 is not positioned wholly parallel to the tunnel wall. This space is filled with grout material in order to prevent as far as possible subsidence on the surface of the ground B.
- the tunnel boring machine 1 can be operated with a number of adjustable control parameters, such as for instance the rotation speed and rotation direction of cutting wheel 2, the moment transmitted by cutting wheel drive 23 onto cutting wheel 2, the pressing force of each of the pressure jacks 5, the pressure of the bentonite supplied via the feed 12, the degree of suction via suction nozzle 13, the quantity and composition of the grout material sprayed around the tunnel wall via feed mechanism 19 and so on.
- adjustable control parameters such as for instance the rotation speed and rotation direction of cutting wheel 2, the moment transmitted by cutting wheel drive 23 onto cutting wheel 2, the pressing force of each of the pressure jacks 5, the pressure of the bentonite supplied via the feed 12, the degree of suction via suction nozzle 13, the quantity and composition of the grout material sprayed around the tunnel wall via feed mechanism 19 and so on.
- sensors 20 for measuring the pressure in the drilling area such as pressure sensors 20 for measuring the pressure in the drilling area, sensors 21 for measuring the hydraulic pressure of each of the jacks 5 and/or the distance over which each of the jacks 5 is pushed out, flow rate meter 22 arranged in fed channel 19 for measuring the flow rate of the supplied ground material, etc .
- the settlement when only vertical displacements are taken into account, or the deformations, when horizontal displacements are also taken into account, can be measured directly using settlement beacons 24, or indirectly using measuring equipment 25 arranged on a building G.
- the measurement data are received in a processing unit and transmitted s therefrom to tunnel boring machine 1.
- the measurement data can be displayed graphically.
- the measuring equipment is placed at a position in front of, above and behind the shield of the tunnel boring machine, in order to be able obtain a good picture of the deformations of o the ground surface caused by the drilling.
- the initial parameters for controlling the tunnel boring machine are determined on the basis of soil mechanical calculations.
- the drilling begins with the setting of these initial parameters.
- the deformation data are sent substantially in real-time to the operator, this deformation data together with the status data being used to operate the tunnel boring machine with control parameters such that deformations (settlement) remain 0 minimal.
- the steps of determining the settlement data right up to operating the tunnel boring machine 1 take place during drilling and are therefore performed substantially in real-time, which means that the time delay is minimal.
- a time delay of a maximum of about half 5 an hour occurs in practice.
- a time delay of a maximum of 5 to 10 minutes can however be realized in some cases.
- Tunnel boring machine 1 is controlled using a TBM control 40.
- This control 40 is o connected using a large number of connecting lines 41a, 41b, .... , 41c, 41d to the various elements of tunnel boring machine 1 for controlling among other things the jack pressure, the rotation speed and rotation direction of cutting wheel 2 etc., as well as to status determining 5 sensors, such as sensors 20, 21, 22.
- sensors 20, 21, 22 In practice many hundreds or more sensors can be applied to determine any of the quantities which are representative for the drilling process. Pressure sensors at various positions, temperature sensors etc. can be envisaged here.
- the control 40 of tunnel boring machine 1 is connected to a control computer 45 which can be operated
- tunnel boring machine 1 takes place for instance by reducing the displacement speed of shield 6 (for instance by reducing the jack pressure in jacks 5) .
- Large deformations can hereby be avoided, since by spraying the grout material as stated o above on the outside of the tunnel wall the ground B can be stabilized to a sufficient extent.
- Such a low displacement speed will however make drilling uneconomic.
- the displacement speed is increased the risk of deformations increases, which may cause damage to
- the operator 0 In order to determine the tunnel path the operator 0 is assisted in a manner known in the field by a laser (not shown) which is disposed in the tunnel and which indicates the ideal drilling path. Making use of o the laser the operator 0 obtains an indication via the control 40 and control computer 45 of the extent to which the actually drilled tunnel path deviates from the ideal path.
- a laser not shown
- the operator 0 is assisted in controlling tunnel
- Determining of the preferred control parameters takes place by inputting into a neural network 46 the data from the settlement beacons 24 or the measuring
- the status parameters which characterize the drilling process are also inputted into neural network 46. Once the neural network 46 has been trained, the output of this network will produce the preferred control parameters. The thus determined control parameters are subsequently made known to the operator 0 in random manner, for instance by means of a graphic display on the screen of control computer 45.
- control parameters defined by neural network 46 can be compared with control parameters stored in the theoretical database 50, which is filled before drilling with theoretically determined control parameters .
- control parameters can be determined for instance by performing theoretical calculations on the basis of a physical model of the subsurface and of the tunnel boring machine.
- the preferred control parameters can moreover be compared with the control parameters from an "as-built" database 51, in which control parameters are stored during the drilling of a previous tunnel, for instance the first tunnel of twin tunnels, or a tunnel previously constructed in a similar ground.
- a warning is generated, for instance in the form of an optical or acoustic signal.
- Operator O can hereby adjust the control parameters manually in order to prevent calamities .
- the deformation data and the status data are used as input and the control parameters used or applied by an operator 0 are used as output to train the coefficients of the neural network. If after a period of time during drilling the neural network has been sufficiently trained, the tunnel boring machine computer 45 can in some cases take over control from operator O.
- a computer program can be run which contains a feed-forward neural network, wherein the neural network learns the historic value of the control parameters and the associated value for the settlement variables.
- the network herein learns the relation between control parameters and settlement variables as these apply to the local ground conditions. On the basis of the relation learned, a prediction can then be made of the resulting settlement variables, given adjustments to the control parameters.
- the network can be implicitly adapted to a changing ground composition affecting the relation between settlement variables and control parameters (in other words, the function F (x) changes as a result of changes in the ground composition, and
- a sliding window of a historic training data set can be used for the prediction. For each measuring point at the drilling front five values are calculated, the
- the output value for learning is the value of a sensor on the shield.
- 5 x 8 40 input nodes, and in this case one output node.
- a training set with 20 times the first data point is taken as starting point, the network is then trained and predicts the subsequent values .
- the measured new values s are added to the training set according to the first-in- first-out principle, whereafter the network is once again trained on the slightly modified training set in order to predict the following values.
- the network o can make a correct prediction, for a set of control variables, of the pressures to be expected on the shield ( (yl) and y(2)) .
- this prediction is also found to be reliable here for a longer time. This makes it possible to predict the results of
- control parameters applied during drilling and the associated values of the status data for later use in a database for instance the as-built database 51, can be stored.
- the invention also includes other applications, such as application in the pressing of pipes into a subsurface, such as for instance pressing steel pipes through a soft ground in order to realize an oil pipeline etc.
- system of the tunnel boring machine computer 45, the neural network 46, the settlement measuring sensors 24 and 25 and optionally the databases 50 and 51 can be connected to a simulator 44 in which the behaviour of tunnel boring machine 1 is simulated.
- a simulator can be implemented in terms of both software and hardware .
- FIG. 3 this is shown in figure 3 with broken lines.
- the simulator can however also function separately of the tunnel boring machine, for instance in order to simulate the drilling process before going ahead with the actual drilling, this being set forth hereinbelow.
- Using the simulator simulations can be carried out in advance for the drilling path which will be followed, with the object of optimizing the drilling path.
- a simulator can also be applied to train drivers or operators. Since in practice the training of operators takes a very long time (a number of years) , and hazardous situations moreover cannot be trained, or hardly so, it is more advantageous to train an operator on such a simulator.
- the simulator can also be applied when calamities occur. Here for instance drilling of the tunnel is halted, a simulation is carried out of the performed drilling work and an assessment is made of the situation to which the TBM must return to once again obtain a stable situation.
- the simulator can be used to enable testing of subsystems of the tunnel boring machine on the premises of the manufacturer of the tunnel boring machine (TBM) to see whether all subsystems are functioning correctly.
- TBM tunnel boring machine
- the simulation of particular subsystems can be replaced during the manufacturing process by the actual subsystems or components at the moment these are ready.
- the simulator can be connected to all subsystems of the tunnel boring machine and a trial run can take place. The test drilling usual in current practice (over more than 200 m) can hereby be avoided.
