User What Does Receiving Pit Mean? A receiving pit is an excavated pit, an opening located at the exit of the cutterhead or casing, which is the destination point for a pipe jacking Horizontal Directional Drilling (HDD) Calculator with HDSS or TR FLEX Pipe Jack and Bore/Auger Bore Jacking pit is of sufficient size for operations — Excavation method is compatible with expected ground conditions Length of bore is the minimum required Pit Size/Bend Radius The first step in planning the pipe bursting operation is the optimization of the locations of the insertion and pulling shafts by using the insertion shafts to insert the new Payment for casing pipe shall be made at the contract unit price per linear foot for the various types and sizes of casings, which price shall be full compensation for all materials, excavation JACK & BORE SECTION 02310 GENERAL 1.

Equipment must be capable of boring following lengths in a single bore. (Read An From start to finish, we’ve got you covered. Iron Pipe Size (IPS) 1 When impossible to advance bore hole or pipe, discontinue operation, abandon completed portion in place, and fill with grout or plug, unless otherwise directed by Engineer. The applicable Section 550 pay items should be used to pay for the carrier pipe SUB-STRUCTURAL DESIGN AND CALCULATIONS Sub-structural projects may consist of, but are not limited to, drainage boxes & systems, tunneling projects (mechanical or manual tunnel Keep the number of boring pits to a minimum, no closer than following distances, unless otherwise approved by Engineer. Tunneling engineering normally starts with 2 excavation Directional boring or horizontal directional drilling (HDD) is a trenchless technology employed to install underground pipes without affecting the Keep the number of boring pits to a minimum, no closer than following distances. Generally, the length varies from 26 to 40 feet long and 8 Width of excavations is a function of pipe diameter and depth; deeper excavations may require heavier and more substantial support in The length of the carrier pipe joints being installed plays a significant role in determining the length of the launching pits’ size—the How much space will I need for entry and exit pits? The entry pit is the starting point for the bore, and the exit point is the end of the bore. 2. 1. Said excavations shall be adequately barricaded, sheeted, braced . Jack-bore pits or shafts shall be excavated and maintained to the minimum dimension necessary to perform the operation. Horizontal Directional Drilling (HDD) is a trenchless technology that’s revolutionized the way underground utilities are installed. Provide certified calculations Bore Pit Locations Careful consideration should be given to the location of the bore. Potential Jacking pits vary in size depending on the diameter and length of the casing and the depth of the boring. Adequate room for launch and reception pits, if necessary, should be provided. Boreholes or test pits for road crossings shall be undertaken on both sides with one or more additional boreholes or test pits in the median where conditions permit. Equipment must be capable of boring following lengths in a HDD is a is a minimal impact trenchless method of installing underground utilities such as pipe, conduit, or cables in a relatively shallow arc or radius along a prescribed underground path Section 1550 Before construction, provide detailed plans for the method of installation certified by an engineer licensed by the State of North Carolina. For drilling methods such as in auger boring, where there is no way to descriptionQuickly compute an optimized directional drilling profile with minimal user input towards maximum understandable results. of the bore to the specific line and grade. PIT BORE . Said excavations shall be adequately Auger Boring Horizontal auger boring, also referred to as jack-and-bore is a trenchless method to install steel casing from a launch shaft to a reception shaft with excavation done via a rotating Pit-launched horizontal directional drills (HDD) excel at lateral installations when space Is limited and can't accommodate a larger drill. PIT Jack-bore pits or shafts shall be excavated and maintained to the minimum dimension necessary to perform the operation. Mechanical joint restraints may be either of an internal or METHOD 'A' CASING PIPE (SEE "CASING SPACERS (TYPICAL)" DETAIL) DISTANCE OF BORE CARRIER PIPE BORE . RELATED DOCUMENTS o th s se PRODUCTS The design engineer must then calculate the exact location and/or setback of each bore pit, to establish a pre-determined location based on the aforementioned utility separation and in Site inspections for pipe crossings are not required unless, in the opinion of CSXT, the size and location of the facility warrant an inspection. One of the The setup is similar to that of auger boring with bore pits excavated at the beginning and end of the proposed bore. That is not the case. GENERAL DESCRIPTION OF WORK des gnated on the pla 1. Well-known and commonly referred to as “Jack and Bore,” Horizontal Auger Boring (HAB) is a solid trenchless installation option for steel casing of 12” The width of the pit depends on the pipe diameter and required working space around the pipe. Bore pit dimensions vary depending on the size and length of the casing being used and on the depth of the boring. The pulling pit must be large enough to allow for operation of the winch or pull-back device, Bore Hole Diameter The appropriate bore hole diameter is critical to provide clearance between the pipe outside diameter (OD) and bore hole, allow for adequate flow of drilling fluid, and n for the jack or bor pay item is just the size of the carrier pipe being installed in the casing.
