Description

Gear wheel 32 which meshes with a centrally arranged drive gear 33 which is driven by the motor 7 through the hub of the base frame 3. If desired, the drive gear 33 can also be driven by its own motor or via a speed change gear T. If desired, the individual gear wheels 32 can also be driven by their own motors.

It is best to have the individual gears 32 and the drive gear 33 helical teeth, as they are in work with broken material. It is also advantageous to shape the other surfaces of the gears 32 and 33 from a very hard material or with a to coat hard material so that the gears act as a breaker for all chunks of earth and rock, who get between them. The helical teeth then allow the broken material to escape.

In the feed direction behind the gears 32, the molding tools each have a molding sleeve 34, which is wedged with the respective gear 32 or made in one piece with this and the one Has helical or helical outer surface 35, which is also best made of a very hard material is manufactured or coated with such the form sleeves 34 rest on the cylindrical outer surface 36 of the respective forming tools 28, 29, 30, while their own helical or helical outer surface 35 on the surrounding soil or soil mixture to form the pipe structures 38,39,40 or 41 is applied The rotation of the sleeves 34 is with the advance of the propulsion device and the pitch of the helical or screw threads correlated to smearing of the walls of the pipe structures 38-41 avoid.

The pipe structures 38-4i have a helical or helical inner surface 42. By the addition suitable binders, such as hardenable synthetic resin, concrete and additives and surcharges, the mixture stabilized to a stable building material It is best to use an epoxy material on one of the kneading plates 10-12 is fed through the channels 43 on the stationary kneading plate 12 behind the aprons 45 of the legs of each U-tube, -immediately before the soil-epoxy resin mixture a catalyst comes into contact with the helical or helical surfaces 35 fed so that the catalyzed soil-epoxy resin mixture in the time in which it is removed from the molds is formed in the pipe structures 38-41, hardened The stabilized, solidified soil then forms permanent helical or helical surfaces 42 organically connected to the soil on the inner surface of the channels. The aprons also serve to secure the meshing zone of the gears 32 and the drive gear 33.

Inside the pipe structures, a feed device 50 engages the forming tools 28-30. Every Feed device 50 consists of a cylindrical frame or a cylindrical sleeve 51 with ei- eo A cylindrical outer surface 52 that fits snugly but loosely in the helical or helical surface 42.

The sleeves 51 also have a helical or helical inner surface and eight slots 56, 56 ', 57, 57', which are arranged on widely spaced chord lines C to the cylindrical outer surface 52 and form four pairs of feed openings. Each feed opening has a feed gear 58, which extends through the opening and into the helical or helical inner surface 42 of the pipe structures 38-41 engages in which the feed device is located. The feed gear 58 or more such feed gears are driven by a suitable drive device, such as on the sleeve 51 mounted axle motors 59, driven.

Each feed device 50 contains at least one hydraulic cylinder 60 which is inserted between the sleeve 51 and engages the fixed part of the associated forming tool between the feed devices 50 and the associated molding tools must be able to move a certain amount of angle so that the feed devices 50 can exert a thrust differential by which the propulsion device is controlled. It it is recommended to use universal joints 61 for this purpose and the cylinders 60 with the aid of the following to control the system described.

The drive system also includes an endless conveyor device (FIG. 1) with an access or work zone 71 at floor level. The conveyor also includes at least a pair of the parallel pipe structures 38-41, which are formed by the drill head and connected in pairs by one of the U-tubes 16 or 17 each will.

If a pair of pipes is used, it serves both to feed the propulsion device and to remove it of the excess soil that arises when the pipe structures 38-41 are formed. Depending on the circumstances however, a conveyor 70 in a pair of pipes for supplying the propulsion device and a second conveyor 70 'in the other pair of pipes for supplying and removing bulk material, for example for Feeding backfill material and transporting ore in underground mining.

The conveyor 70 consists of an indefinite number of conveyor or mobile transport units 72, the number of which depends on the length of the system Units can be added in the work zone 71 if this is necessary in the course of the advance will. For this purpose, the "endless" conveyor in work zone 71 has a maintenance loop 73 provided that the removal, emptying or servicing of returning conveyor units as the filling, Operation and insertion of mobile conveyor units for sending to the jacking device enabled

Each mobile conveyor unit 72 consists of a housing 75 and a number of gears 76 which are flexible, z. B. with the aid of the spring suspension shown schematically at 77, are attached to the housing. One or more of these gears are from a suitable device, for example an electric Ashsi-KKor 78, powered.

It will be understood that the feed gears 58 of the feed devices 50 and the gears 76 of the mobile conveyor units 72 are provided with helical teeth. They are therefore essentially moving linearly through the pipe structures 38-41, so that the Major parts of the feed devices 50 and the mobile conveyor units 72 do not spiral through the System are moved, but this axi ^ il vnit only occasional, insignificant rotation with respect to the helical or helical surfaces.

Each housing 75 of a mobile conveyor unit has a maintenance zone 77 and a transport zone 78. The Maintenance zone 77 may have a suitable access opening 79 or a device for inserting a power supply
