2 VARIE The Grundopit family... What they have in common Practical job site experience has shown that steerable mini bore rigs have to be applied, when space conditions are restricted, when complicated house connections have to be installed but non-steered soil displacement hammers cannot be used due to the terrain when a quick, clean, precise and economic solution is required, when open-trenching should be avoided or is actually impossible to use and when controlled drilling is required for security reasons. The main application is the subsequent installation of gas and telecommunication house connections in protection pipes up to OD 63. Parallel installations, street and small inshore water crossings are also possible. Depending on the type, the Grundopit is started from the pit or out of a shaft building. Depending on the capacity of the machine, the maximum upsizing Ø is 200 mm. Depending on the equipment used the Grundopit can also be used in heavy soils with a hammer bore head, which is driven by a hydraulic/pneumatic combined aggregate. The Grundopit can work either with a simple water-polymer or a Bentonite suspension, depending on the requirements. Suitable mixing systems are available at your choice. Location of the bore head and arrival in the cellar or the connection pit as planned. The optimum system for starters is doubtlessly the standard version, which can be upgraded into the power version due to the TT modular system.

4 PERFOR... There s a lot inside On unpaved path-ways, in inaccessible terrains or with ice and snow on the road, drivers appreciate the all-wheel drive. The bore crew also has to be able to react quickly in certain circumstances. In those cases, it is always better to have "a little bit more underneath the hood". This provides security and improves the chances of reaching the goal. Combination aggregate KA 38 with compressed air and hydraulic connections The difficult pilot bore conditions in heavy soils call for the application of Grundopit Power. Compared with the Grundopit Standard, using the combined drive aggregate KA 38 increases the Grundopit performance immensely. The torque is increased from 600 to 1000 Nm. the simultaneous supply ofcompressed air allows operation of the hammer bore head. When it meets with resistance (larger stone inclusions, solid rock, building rubble or brickwork), the hammer effect is activated automatically, thus guaranteeing a smashing success. The advantages of professionally composed drilling fluids with the high-capacity mixing and pumping unit MA 09 guarantees the successful pulling in of pipes up to 160 mm Ø in lengths of < 80 m. Mixing and pumping system MA 09 Mixing tank 1100 l content, with internal distribution system Fresh water tank 200 l (optional) HP pump can also be used as a washing device by re-setting the suction to fresh water. The MA 09, which can also be used for other bore rigs, can be driven with the hydraulic aggregate of the Grundopit Standard, Type LTT 40 P, or with the combined aggregate KA 38.

6 INNO In minimum space... With the Grundopit Manhole fibre glass cables can be installed in protection pipes ND 50 (out of a pit and into a cellar) or in protection pipes ND 100 (from manhole to manhole) for the first time without trenches. And this is the way it works: The bore rig is set up on a working platform, which has been positioned and anchored in the manhole beforehand. The working platform, driven out by hydraulics, adapts itself to the inner diameter of the manhole utilising the support given by the manhole walls. Holding ropes secure the working platform additionally. First of all a core hole bore, connected by an adapter, bores a 150 mm hole through the manhole wall (small photo, below, right). After this the tool is exchanged, the standard bore head or the specially designed hammer bore head for heavy soils is screwed to the 50 cm long drill rods. Then the rods are thrust forward swiftly, the bore course is constantly monitored and corrected, if required. Drilling fluid is usually necessary, it can be prepared in the drilling fluid mixing unit belonging to the machine. After the drilling fluid has been used, it is collected in a facility and disposed. The bore head can "drive" via pre-drilled core hole bore, through the house wall into the cellar. After the pilot bore the bore hole is expanded and the protection pipe is pulled in. Setting up the working platform and the Grundopit-Manhole Start from the manhole to the service room of the building The Grundopit establishing the core hole bore from out of a gully hole.

8 FUNCT schwenkb Kran.... Practical Developing the Grundopit Compact, in close co-operation with GDF (Gas de France) aimed at: minimal dimensions for the smallest pits possible (L x W = 800 x 500 mm) and a bore rig for house connections in the natural gas domain, as fully mechanised as possible. Rig boom, to be set up in longitudinal or cross direction, with "lift" for lowering or lifting the drill unit. The result: drive, mixing unit and bore rig with rod box are installed on a track-laying undercarriage as a bore, drive and headstock unit. That way the complete boring equipment can be transported to job sites which are difficult to access, requiring as little space as possible. Driving and boring operation are regulated by remote control. Operation is carried out from outside the pit. The pivotable rig boom with integrated bore rig, which can be driven out horizontally for transportation and vertically for operation, is mounted to the bearing unit. The sheeting frame with drill rig is lowered into the work pit with a hydraulic lifting device; as soon as it has been fastened above the supply line in the required direction, it is ready for action. Top view of the drill unit The rig boom with sheeting box can be lowered 1.50 m deep into the pit (800 x 500 mm) and supported by the pit walls with the help of hydraulics. The drill rods are inserted in the rig from the top and lowered to the drill axis via lift transport, where they are screwed together automatically. After having been pulled in with reverse gear, the house connection line is equipped with the corresponding coupling facilities (fittings etc.) and connected with special "manipulators to make it gas- and pressure-proof. Carrying out the job in this way and using this connection technique, house connections can be installed in depths of up to 1.50 meters. Positioning the rig boom, depending on the bore direction The rig boom is lowered into the working pit 8

11 Establishing the lead through the wall: 1. Location of the bore head in front of the cellar wall TY... trenchless - right into your cellar Usually, the pilot bore starts in the connection pit or from the manhole, if a house connection is being installed subsequently. The bore head is located in front of the cellar wall from the supply room inside, then it is over-bored from inside with a core hole bore. When the boring tools have been changed the pipe, equipped with a special wall duct at its end to seal the cellar wall from outside and within, is pulled in. Advantages of the Grundopit technique flexible application due to the optimal adaptation to different working conditions high installation precision, quality and safety thanks to the trenchless installation method damaged surfaces are avoided the air-driven add-on hammer bore head enables thrust in heavy soils (Pit Power and Pit Manhole only) hydraulically and compressed air-driven combination drive aggregate (Pit Power and Pit Manhole only) by using different mixing systems, the Grundopit can be operated with a simple water-polymer or a Bentonite suspension leak-proof wall duct system can be started from manholes sized 1 m add-on core hole drill (Pit Manhole only) complete boring equipment onone track ed undercarriage (Pit Compact only) 2.
