碩士 === 國立高雄應用科技大學 === 土木工程與防災科技研究所 === 91 === Horizontal directional drilling (HDD) method is a subsystem of the trenchless technology. In Taiwan, due to misjudgment of the soil property and the delay of the installing products sche- dule during the installing products construction, it often caus- es the failure of the HDD installing products as well as the im- pact to the society. Besides, owing to the lack of HDD installi- ng products technology standard procedure, there is no standant foe the design and construction units to follow up and there is no resolving policy could be quoted for difficulties encountere- d. In this study, we expect to take advantage of following man- ners to study the installing products technology of HDD method: (1)to review the academic papers; (2)to check of practical cons- truction; (3)to apply the study method of decision-making analy- sis and risk management. We aim to study from the planning, fa- cilities, construction, materials and management sides to compr- ehensively investigate the HDD installing products technology. We hope that this study outcome could provide public constructi- on related units and civil’s factories using installing produc- ts technology of HDD method to be as a skill basis on installing products technology of HDD method in order to reduce the failure rate and shorten the time schedule and efficiency of installing products, as well as the constructive quality. The main outcomes in this study include: (1) installing pro- ducts technology program: to provide drilling path and construc- tive outcome data using excel spreadsheet and apply linear prog- ramming method to obtain the best target function of installing products for related industry to assemble; (2) installing produ- cts equipment: facilities, constructing team structure and HDD pull-back force figure; (3) installing products technology: set up construction standard operation and resolve problem strategy and apply fault tree analysis to analysis the failed reason of installing products. This provides reference for the industry. (4) installing products materials: to build up the calculated procedure and method of drilling fluid and bentonite clay usage- , build up the model of speed of mixing mingle and pull-back in- stalling products; (5) installing products management: to build up the diagram and strategy of constructive technologic managem- ent to avoid the timely calculation in the constructed site and shorten the time of installing products as well as to enhance the installing products technology.
