Horizontal Directional Drilling is a trenchless method for installing a product that serves as a conduit for liquids, gasses, or as a duct for pipe, cable, or wire line products. It is a multi-stage process consisting of site preparation and restoration, equipment setup, and drilling a pilot bore along a predetermined path and the pulling the product back through the drilled space. When necessary, enlargement of the pilot bore hole may be necessary to accommodate a product larger than the pilot bore hole size. This process is referred to as back reaming and is don at the same time the product is being pulled back through the pilot bore hole.
Alignment of the bore is accomplished by proper location of the drill bit head as it is being pushed in the ground by the hydraulic jack. Location and tracking of the drill bit is determined by an above ground radio detection device which picks up a radio signal generated from a transmitter located within the drill bit head. Radio signal is then electronically translated into depth and alignment. In order to minimize friction and prevent collapse of the bore hole, introduction of a soil stabilizing agent (drilling fluid) is introduced into the annular bore space from the trailing end of the drill bit. The rotation of the bit in the soil wetted by the drilling fluid creates a slurry. The slurry acts to stabilize the surrounding soil and prevent collapse of the bore hole as well as provides lubrication.
Cyrus L. Bowen Construction Co. can service your under ground projects by doing directional drilling.
As an experienced professional horizontal directional drilling contractor, we have worked with utility, pipeline and communication contractors, as well as individuals. We have been in business for 40 years. We work in a 300 mile radius of the Marietta, Ohio area.
Our experiences have included drilling under railroads, waterways, highways, driveways and congested areas.
Completed projects have consisted of steel pipe, PE pipe, interdict pipe and PVC.
Thrust boring Method of horizontal Auger boring is a process of simultaneously jacking through the earth while removing the spoil inside the encasement by means of a rotary auger. In unstable soil conditions, the end of the auger is kept retracted back inside the encasement so as not to cause voids. In stable soil conditions, the auger can be extended beyond the end of the encasement to facilitate the breaking down of the spoil removal. In addition, in stable soils, rocky soils and rock conditions, cutting heads can be attached to the end of the auger or cutting head units can be mounted to the front of the encasement to actually bore the hole for the encasement to enter.
Cyrus L. Bowen Construction has been performing auger boring for 40 years. The company has now expanded from 2” to 48” and beyond.
We will subcontract a job or contract a whole job.
With several size auger machines we can met your boring needs.
Working along with your heating and cooling representative, we can install your geothermal loops underground and make ready to tie into your home.
Pipe ramming is a trenchless method for installation of steel pipes or casings which a pneumatic tool is used to hammer the pipe or the casing into the ground while the excess soil from creating the borehole is removed to the surface. The method is frequently used under railway and road embankments. When casings are installed, pipes of other types for distribution of sewerage, water or gas, or electrical or telecommunication cables are subsequently inserted. The method is non-steerable.
Compared to other trenchless methods such as augering and directional drilling, pipe ramming can save both total installation time and costs under favorable conditions. Installation time can often be nearly 40% shorter than in augering because required width and depth of pits are smaller and actual installation is faster (40 to 60 feet sections can be rammed in half an hour while auger boring the same distance requires half a day).
Pipe ramming essentially involves the ramming of steel pipe through soil using pneumatic devise rather than creating a bore hole. Here are some things to keep in mind for pipe ramming:
· Uses steel pipe only
· Optimum size is 4” to 60” in spans up to 400’
· Requires a bore pit
· Can be used in many types of soil conditions
· Since smaller diameters of pipe can be deflected by obstructions such as boulders or cobbles,
..........accurate information on soil conditions is essential
· The main limitation is less control over line and grade so setup is critical
Cyrus L. Bowen Construction is experienced and qualified in pipe ramming. We have the equipment and personnel to do any size job.
We have successfully rammed all sizes of pipe. Our biggest job was successfully completed with 100’ of 48” pipe and 80’ of 66”.
