To this end, this chapter presents basic information about the methods, equipment, and applications available for use in trenchless utility construction, and provides insights into conditions and situations where trenchless applications would not be appropriate, thus requiring trenching operations.
This chapter also contains the results of the survey conducted for this project as they pertain to the use and perceptions of trenchless technology by various state transportation agencies.Īs technology advances, the ability to perform trenchless utility installation and maintenance will also advance, allowing a progressively greater proportion of such work to be completed without trenching through the pavement structure. This chapter presents information that can help transportation agencies effect this reduction while maintaining access for all those legitimate and responsible parties that request it. While controlling these cuts can help maintain order, ensure that the repairs are done in an orderly manner, and encourage utility companies to share resources and trenching operations, it is also desirable to decrease the number of utility cuts necessary. The previous chapter discussed methods that state and local agencies can implement to control the frequency of pavement utility cuts in highways and streets.
Reducing Pavement Cuts by Integrating Technology The PD-2 and PD-6 both have analog steering capability and Analog Detection Technology, allowing them to determine position within inches and steer around pipes and foundations.Pavement Utility Cuts 4. The PD-4 and PD-6 horizontal directional drilling tools use digital steering and Digital Detection Technology with target-in-the-box locating and real-time readouts to determine their location within inches. It has an 84,822-lb thrust force at 3,000 psi and installs 8-inch ID pipe at 7 feet per minute. PD-6 – Also designed to work from small spaces and in difficult soil, the PD-6 also works with pipe bursting or directional thrust boring. PD-4 – Designed specifically for operation from limited spaces and in rough soil conditions under areas that can’t be disturbed, such as roads, the PD-4 has a 37,714-lb thrust force at 3,000 psi, installing 6-inch ID pipe up to 9 feet per minute. PD-2 – A one-man controlled machine with steering designed to make installations from basements and under porches, yards, driveways, and narrow roads.

Directional boring refers to smaller-diameter bores over shorter distances while horizontal directional drilling, or HDD, indicates larger diameters and longer distances. Directional boring, also known as horizontal directional drilling, is a type of low-impact method using surface-based trenchless equipment for installing pipes, cable, or conduits along a slight curve or grade.
