- the invention relates to a system for the hydraulic discharge of cuttings. Furthermore, the invention relates to a system for the system for generating a stable fluid pressure of a drilling fluid in the region of a cutting wheel of a designed for wet drilling tunnel boring device at a working face.
- tunnel boring machines When drilling boreholes from a start point to a destination point along a given drilling line, various types of tunnel boring machines are used depending on the soil or rock in question. Such tunnel boring machines are used when the tunnel boring machine is advanced along the drilling line without pilot drilling or the like. The locomotion can be either via an advance against abutment in the already created tunnel or via a feeding or Nachschieben the pipe segments themselves done outside the created tunnel. Even whole pipelines can possibly also be used only in partially prepared form to feed. Such a feed then takes place via a feed device, for example a so-called pipe thruster or a press frame, when individual pipe segments are pressed into the ground. The release of the soil takes place with a drilling tool, such as a cutting wheel. The loosened cuttings are brought through the drilling tool into an area behind the cutting wheel and carried away from there.
- a feed device for example a so-called pipe thruster or a press frame
- the choice of the type of tunnel boring machine depends on the geology. If the ground in which the tunnel is to be built consists essentially of unstable mountains, a wet drilling method is used in which a face bridge support is used to stabilize the hole and the surrounding soil. For drilling fluid is introduced in the region of the cutting wheel, and the space between the working face and cutting wheel is filled with the drilling fluid. The drilling fluid, which is provided in the region of the drilling tool, is pressurized in order to counteract the pressure prevailing in the mountains of the water and thus to stabilize the working face.
- Is stable mountains available can be worked without support of the face. This means that the area of the working face and the portion behind the drilling tool are not completely filled with drilling fluid. Instead, the drilling fluid is used to bind dust and cuttings.
- the removal from the section can be done in several ways. Among others, screw conveyors or conveyor belts are used.

It is provided that in the stable mountains, the drill cuttings is conveyed away via a jet pump integrated in the section behind the drilling tool. In non-stable mountains where an east-breast support is used, the jet pump is instead closed and the delivery is carried out via a centrifugal pump located in the feed line, which is located outside the tunnel, for example in the shaft or above ground, in JP 2001-182486A. The centrifugal pump pumps the feed liquid into the drilling area and then via the feed line the drilling mud mixed with the drill cuttings via the feed line from the drilling area. A use of a jet pump in wet operation is not shown.
- the cuttings can spontaneously settle in air bubbles in the delivery line and block these clogs. Furthermore, this makes it possible to minimize the high pressure losses in the jet pump in that, since only small delivery lengths have to be bridged with the jet pump, the pressure in the treble line can be kept lower. The removal of the cuttings from the separation tank then takes place with a centrifugal pump.
- the object is to provide a tunnel boring machine and a system for the hydraulic discharge of drill cuttings, with which larger advance lengths can be achieved, especially with smaller diameters, in particular with diameters which are not accessible.
- Tunnel boring machines in which the working face and the section arranged behind the drilling tool for receiving cuttings are filled with a drilling fluid as a drilling fluid, are also known for this purpose.
- the drilling fluid is usually a bentonite suspension.
- the drilling fluid With a feed pump, the drilling fluid is introduced via a feed line in the region of the working face, and the drilling fluid is placed under the necessary pressure to support the working face. It is important in the face chest support that the working face support pressure is kept constant, in particular in order to avoid overburdening at low overburden at too high pressure or burglaries of liquid from the mountains or uncontrolled flow of mountainous into the bore.
- UA, DE 42 13 987 A1 discloses a tunnel boring device with working face support, in which the section for receiving drill cuttings behind the cutting wheel is subdivided with a wall into two spaces in fluid communication with one another.

- drilling fluid mixed with the drill cuttings is sucked from the section via a suction line by means of a feed pump and conveyed through the tunnel behind the tunnel boring machine by a conveyor line. Possibly. Already in the tunnel treatment stages are interposed or it is also used several feed pumps to ensure the entire promotion to over days. Centrifugal pumps are used as feed pumps.
- a face breast support is also possible without the provision of compressed air in conjunction with the chamber division.
- the driver of the tunnel boring device reacts in time to pressure changes.
- the propulsion speed, the delivery pressures or delivery rates and the feed pressures and feed quantities must be adequately monitored and regulated. This requires a lot of experience and attention from machine operators.
- a further object is to provide a tunnel boring machine and a system with which it is possible to more easily keep the working face pressure of the drilling fluid constant.

- a shut-off valve 17 is provided in the suction line 14
- a delivery line 19 is provided at the delivery port 18 of the jet pump 15
- the jet pump 15 has a tether connection 21 for a tether 20.
- the feed line 13 extends from the above-ground systems 30 or from the shaft 40 through the already introduced pipeline or tunnel 50 already created.
- a feed pump 22 is provided in the feed line 13.
- a drive pump 23 is connected, which is designed as a high-pressure pump.
- the delivery line 19 is connected to a separation plant 31 for separating the drilling fluid from the cuttings. From the separation system 31, the feed pump 22 and the propellant pump 23 are supplied with drilling fluid, which then in turn promote them via the feed line 13 or treble 20 to the cutting wheel 1 1 and to the jet pump 15.
- the region of the cutting wheel 1 1 at the working face and the portion 12 is supplied via the feed pump 22 through the feed line 13 with drilling fluid.
- the jet pump 15 is also supplied with drilling fluid by the drive pump 23 via the haulage line 20.
- the driving fluid enters the jet pump 15 through the haulage connection 21.
