TRENCHLESS PIPE INSTALLATION WITH IMPACT MOLES
Thepneumatically drivenimpact moles work according to the soil displacement method. Unlike steerable horizontal boring machines, the non-steerable mole hammer compacts the spoil into the surrounding soil when moving forward. Thus a channel is produced, into which short pipes with smooth sockets, or long pipes made of plastic (PE, PVC or PE-X) up to OD 160 or cables are pulled in. Depending on the type of soil, lengths up to 25m can be either pulled in directly or later on. For operation, a compressor with 6 – 7 bar operating pressure is required. That way, crossings underneath valuable surfaces and house service connections can be established with the mole hammers in a cost-effective and environmentally friendly manner.
The optimised design of the new GRUNDOMAT impact moles features new technical solutions, which further improve durability and minimise time and service effort for trenchless pipe installation. The variety of applications with the mole hammer is also retained and new options, such as servo- control for small machine sizes, simplify handling.
WORKING PRINCIPLE OF THE GRUNDOMAT IMPACT MOLE
The GRUNDOMAT soil displacement hammer’s high target accuracy is due to the 2-stroke principle. With this proven concept, the piston initially strikes the chisel, which advances forward in order to produce the bore hole and to destroy any obstacles along the way. The casing is impacted in the second stroke and pulled in with the pipe attached. That way peak resistance and casing friction are separated and alternately easier to overcome. This makes the GRUNDOMAT mole hammer work dead on target even in stony grounds.
ADVANTAGES OF IMPACT MOLING WITH GRUNDOMAT
- High penetrating power and reliable thrust
- On-target pipe installation in 2-stroke principle thanks to movable head
- With crowned or step head for pipe installation even in difficult soils
- For house connections and under crossings up to 25 m in length
GRUNDOMAT comes in a variety of sizes to suit conduit and trenching requirements including 45mm, 55mm, 65mm, 75mm, 85mm, 95mm, 110mm, 130mm, 145mm, 160mm and 180mm. CONTACT US for quote.
