TT TECHNOLOGIES INC 17 K Cutting Shoes The cutting shoe is an integral part of the pipe ramming process see Fig 28 Before the operation begins it is tack welded to the tip of the leading pipe Its primary purposes are as follows Strengthens the tip of the leading pipe for maximum penetration through difficult soil and rocks Steel pipe Reduces both external and internal pipe friction due to its oversize cut Protects the pipes coating or insulation Cutting shoes also create a channel for the flow of a bentonite polymer mixture Also the cutting shoes conical internal surface reduces soil displacement and influences the bores accuracy CUTTING SHOE SPECIFICATIONS D1 D2 D3 Weight Part N Ibs kg df eae Pee roe meen 190 8 6 3 250 12 9 327 13 5 343 11 8 300 14 1 358 14 5 368 12 8 325 21 0686 18 8478 FIG 28 CUTTING SHOE SPECIFICATIONS Light and water retentive soils require a special cutting shoe The outer cutting ring encompasses only the top two thirds of the pipes circumference see Fig 29 This eliminates the cutting action along the bottom of the pipe and reduces the pipes natural tendency to sink due to gravity and the overcut of the outer cutting ring Cutting shoes are available through TT Technologies and are reusable Contact TT Technologies for specific information regarding cutting shoe requirements and specifications 18 TT TECHNOLOGIES INC FIG

4. INSTALL SEAL OFF PLATE AND SAFETY STAKES AWARNING A y WARNING Without Safety Stakes the compressed air will blow the Seal Off Plate out of the pipe Always correctly install two steel Safety Stakes Failure to do so could result in severe personal injury or death 3 With the air compressor turned off connect the airline to the Seal Off Plate and turn the air line s valve to the open position 4 Start the air compressor and then gradually open the airline s valve from the compressor until full air pressure is entering the pipe 5 The soil will then be blown out of the 3 pipe If it does not blow out then the og a di compressed air was able to escape In this case a Polyurethane Pig should be used Follow the same above steps but insert the Polyurethane Pig into the pipe before the Seal Off Plate is installed see Fig 33 This will force the air pressure to build up because it will not be able to escape past the pig FIG 33 POLYURETHANE PIG 22 TT TECHNOLOGIES INC If the previous steps do not successfully work then internal friction caused by wedged rocks or other materials are overcoming the compressed air In this case water pressure should be considered as a viable option but be careful not to exceed the pressures listed see Fig 34 MINIMUM SPECIFICATIONS OF THE SECURITY STEEL BARS Steel Bars Type in mm in mm in mm in mm psi bar ST 50 6 25 x 0 2 159 x 5 1 1 50 38 1 4 00
