Oil shale is an unconventional energy source, and it also a potential petroleum substitute. Nowadays, the shortage becoming more prominent, oil has attracted attention of researchers all over world. Borehole hydraulic mining effective method to exploit underground which prominent advantages than other conventional methods. Jet devices are key component borehole mining, include straight cone nozzle, organ pipe nozzle self-excited oscillation pulsed jet nozzle. Also, reasonable parameters...
This paper introduces a new shear reinforcement beam-column joint mechanism—the twisted opposing rectangular spiral—and carries out numerical and experimental investigates. Converting the conventional discontinuous system into continuous in different reinforced concrete structural elements improves energy dissipation capacity ductility. The proposed has an inclined characteristic that intersects cracks at more favorable angle. In addition, considerably eliminates slip observable hooks of...
Many utility owners in the United States are actively searching for new and innovative rehabilitation techniques to help them regain control repair large tracts of their networks; moreover, traditional open cut replacement is too costly slow keep up with demand. trenchless such as Spray-In-Place Pipe (SIPP) lining have been adopted by municipalities renew aging pipeline systems. The further development SIPP linings could benefit water community around world. play a key role controlling...
Interlocking pipe joints have been utilized in the trenchless technology industry for over 20 years. This allows a segment with notched male end to be joined female by pressing them together using axial force, eliminating need circumferential welding of segments. Although familiarity these is well established, mechanics interlocking process has received little attention literature. paper provides insights into mechanical behavior interlocking, press-fit that secure steel casings auger boring...
Demand for underground pipelines and the rehabilitation of existing utility infrastructure has been increasing due to urban expansion, continuous development, deterioration buried assets. Often, conventional cut cover (e.g., open-trenching) is method choice when rehabilitating or installing new pipelines. However, some utilities cross under railroads, an interruption railway operations may result in significant economic losses that make it impractical consider open-trench installation....
The experiments mainly focus on estimating the water jet performances and breaking oil shale efficiencies of devices, so as to compare different devices propose parameters borehole hydraulic mining for shale. In fact, thejet devices' can be evaluated bythe striking force effect high-pressure produced by itself.Under same experimental conditions, greater or more significant, better performance device. Moreover, experiment alsobe used proposing theparameters shale.Therefore, main aim areto...
Pneumatic hammers are often used to assist during horizontal directional drill (HDD) pullback operations when difficulties encountered pipe installation. When properly used, pneumatic have proven be a valuable resource in HDD operations; however, the use of should carefully evaluated avoid damage or girth weld failure. apply cyclic load on cross-sectional area. The nature loading analyzed evaluate duration hammer can reduce potential fatigue This paper explores applied by and presents...
Abstract Direct Pipe® (DP) is an innovative trenchless construction method that combines aspects of micro-tunneling and horizontal directional drilling (HDD). In the DP method, ground excavation pipeline installation are simultaneous. this jacking frame in replaced with a pipe thruster coupling eliminated. Additionally, reaming bore hole, which common HDD The typically applied when subsurface conditions beneath surficial obstacle not conducive for due to final hole diameter, granular soils,...
The installation of the pipe, or pullback, is a critical component in any horizontal directional drilling (HDD) project, not only for placement pipe but also long-term behavior during its operating life. An accurate pull force estimate necessary to safeguard integrity installed pipeline and select appropriate HDD equipment. There are several analytical methods used required install pipe; however, these assume static approach neglect dynamic nature pullback operations taking place as each...
