高雄捷運紅橘線交會大港埔圓形站體連續壁施工

CONSTRUCTION OF ROUND DIAPHRAGM WALL OF DAKANGPU STATION AT CROSSING OF RED AND ORANGE LINES OF KAOHSIUNG MASS RAPID TRANSIT

高雄捷迎紅橘綜交會大港埔圓形站體為高雄捷迎路網通車之要徑工程。因此,為維持正常交通服務水準、有限工期、施工條件及安全等,連續壁施工選用水平多軸回轉式切削機以維持品質、控制挖掘精度及施工速度,另為避免造成連續壁之偏壓作用而損壞,站體之開挖順序安排亦為設计及施工人員重視之課題。

Since the Dakangpu Station is one of the key points for KMRT Project at aspects of control of traffic flow, construction period, construction conditions and safety, Electro-Mill-VisionX is adopted in the construction of round diaphragm wall to maintain the quality, speed and accuracy on digging. The determination of the excavation sequence of the station is an important issue to designers and constructors for preventing damage caused by the effect of uneven side pressure of round diaphragm wall.
