機場捷運延伸線潛盾機簡介 Introduction to Shield-Tunneling Machine of TIAA MRT Extension Line
機場捷運延伸線潛盾機構造(含切刃配置)示意圖

機場捷運延伸線CM01區段標以潛盾鑽掘為主,上、下行線潛盾隧道全長合計3,221m,地質為砂岩(大南灣層)及卵礫石(中壢層),最大開挖坡度為4.521%,覆土深度為11.2~20.1m,地下水位為GL-1~5m,最小曲率半徑為100m,最大礫徑為ψ0.93m。依據上述地質及線形資料,潛盾機型式選擇「密閉型泥土壓式」,其設備諸元詳如下表。
施工順序為兩部潛盾機先後自老街溪站(A22)發進至環北站(A21),到達後棄殼並拆解內部組件,運至老街溪站(A22)工作井以新機殼重新組裝後,往中壢車站(A23)方向掘進,途中在橫渡線路段以拖行方式通過後,續行掘進,最後於中壢車站(A23)到達並棄殼,拆解內部組件,運離工地。
2部潛盾機預定104年12月及105年1月運抵基隆港,隨即運至老街溪站(A22)發進井進行組裝,投入潛盾隧道鑽掘工作。

The total length of shield tunnel section in CM01 tender of TIAA MRT extension line is 3,221m inclusive of northbound and southbound directions. The geological substance of bored grounds is sandstone formation(Danawan section) and cobblestone formation (Zhongli section); maximum excavation slope is 4.521%; ground depth is 11.2 to 20.1m; underground water level is GL-1 to 5m; minimum curvature radius is 100m; and maximum cobblestone diameter is ψ0.93m. According to the geological data, the shield-tunneling machine in this project adopted the "Shielded Earth Pressure Type" machine and the detailed apparatus is as the following table.
Regarding the engineering procedure, first, the shield-tunneling machines operate successively from Laojie River Station (A22) to Huanbei Station (A11) where the external cases are discarded, uninstalled and transported back to Laojie River Station (A22); then, the machines start again from Laojie River Station (A22) with new cases and excavate towards Zhongli Station (A23) during which the machines tow across the crossover sections. Same as above, at Zhongli Station (A23), the external cases are discarded internal parts are uninstalled then transported away from the construction site.
The two machines are scheduled to arrive at Keelung Port on Dec. 1, 2015 and Jan. 1, 2016 respectively. Subsequently, the machines will be transported to Laojie River Station (A22) to assemble and install and embark on the tunnel excavation work.
