| 摘要(中) |
近年來為提昇生活品質及配合國家政策與世界潮流，各地都會區之公共建設相繼大規模興建，如電信、電力、自來水、污水下水道及家庭事業廢水管等維生管線工程，由於台中都會區近來大量興建地下管線埋設，為避免影交通，造成社會成本，許多道路已不容許以傳統之明挖覆蓋工法來進行地下管線埋設工作，大多以免開挖工法進行施工，並已被推進及潛盾等工法所取代之，但在台中地區卵礫石層中進行中大型管推進及潛盾工法之施工，施工經驗尚不足，故兩種工法仍待考驗。 本研究針對台中地區中部科學園區污水放流管線工程進行現地調查及案例蒐集，並蒐集相關現地資料與國內外文獻加以整理比較。中科污水放流管線共有四標工程，取得之蒐集資料包含：中科現況與路線、地質鑽探與地層分佈、各地區卵礫石顆粒大小與分佈、各施工點覆土深度、推進與潛盾機具機型（掘進機本身及切削面之構造）、掘進機之損耗及維修情形、潛盾掘進（含扭力與推力）及速度、出渣控制狀況、遭遇困難及施工延緩因素、困難克服方法、地表沉陷量及影響範圍、傾斜管觀測資料、施工過程地表隆起或滑移情形、開挖及推進長度、推進裝置與推力大小、地下水狀況與影響、工作井施作情形及地盤改良、非直線施工之影響等。 由於台中地區地質大多以卵礫石層為主，其本身自持性佳、質地堅硬且單壓強度高等，對於推進機與潛盾機施工機具掘削面盤刀刃磨損相當嚴重，其他機具設備損耗亦相當頻繁。掘進力及速度與切削刃盤之扭力及螺旋機壓力相互影響，當扭力過大，則推進速度需減慢與推力降低，螺旋機壓力扭力小則加速迴轉速，使排土增加。掘削刀刃原預計更換距離比實際更換距離短程。各標處之地表沉陷量觀測點與土中傾度管觀測，其僅呈現微量增減之變化並無明顯之下陷或隆起現象產生及位移量變化差異不大，均在警戒值容許範圍內。 另外，本研究將上述所調查與案例蒐集成果之資料，與先前蒐集國內外，加以整理與分析並比較之，期能有助於未來有關在卵礫石層中推進及潛盾施工與設計提供參考。 |

| 摘要(英) | In
order to enhance the quality of living and to meet government’s
policy and worldwide trend, a lot of public constructions are
being built during recent years. These constructions include
telecommunications, electric power, water pipe, sewage pipe,
household waste pipes and lifeline constructions. There are many
on-going underground utilities have been built in Taichung.
No-dig methods, such as pipe jacking and shield tunneling
methods, have been used to replace open-cut excavations to avoid
traffic impact and social cost. Methods used for underground
constructions in gravel formation, however, are still under
exploration due to lack of experience. This objective of this study is to focus on investigation of Taichung base waste water outflow pipeline construction and to synthesize the construction cases and field data to compare with other references. Taichung base waste water outflow pipeline constructions are divided four sections. Collected data include the followings: Taichung base waste water outflow pipeline construction status, geology, boring logs, granular size and distribution of gravel formation, overburden depth, pipe jacking and shield machine(structure of machine body and cutting face), attrition and repair of shield machine, shield tunnel (rotational force and jacking force ), pulling out speed, soil emission, encountered problems, solution used to overcome problems, ground surface settlement and impact, raise or slip of ground in process of construction, length of excavation and jacking, jacking installation and jacking force, condition and effect of underground water, and effect of unlined construction. Gravel formations are the most common formation in Taichung area in Taiwan, most of the gravels are hard and having high strength and strong interlock between gravels. Thus, it is difficult to cut using any machine. Those machines will be easily worn and torn seriously, especially the cutting face for the pipe jacking and shield tunneling methods, in the gravel formation. The results show that the jacking force, torque of cutting face, and pressure of screw machine during tunnel excavation will interact with each others. As the torque increases, then the excavation speed and thrust may decrease. In order to increase the volume of excavation, the pressure inside the screw and the rotation speed should be lower down and increased, respectively. The cutting disks inside the cutting face should be replaced after certain tunneling length, and the actual length is shorter than the expected. Monitoring results from the ground settlements and inclinometers show that only small changes are recorded and they are within the tolerance range. In addition, this research results are compared with the previous data. These data are all synthesized, analyzed and compared. Results obtained from the studies could be used for construction and design in gravel formation in the future. |
