Hong Kong U TBMEquipment introduction

Offline this timeU TBM，Device width 9.36 meters×Height 20.72 meters，It is tailored for the infrastructure construction of the northern metropolitan area of Hong Kong.，Help to improve flood control capacity。The total excavation length of the project is 1000 meters.，Formed box culvert section width 6.15 meters×High 6.35 meters，The project is sandy silty clay，The surrounding groundwater is abundant，And there is more silt in some sections.。In view of the high risk factor of the traditional open-cut construction method of the project,、The construction enclosure occupies a large area.，Combination of China Railway and EquipmentUExperience of successful application of m-type shield in underground pipe gallery，Innovative integration of shield and pipe erecting machine，Comprehensive pipe gallery transportation has been realized.、Excavation、Support、Tunneling、Erection、Fficient construction of side seam fil integration，It has brought a new breakthrough in technology for the mechanized construction of the assembled comprehensive pipe gallery.。

U TBMConstruction method of box culvert engineering

U TBMThe construction method of box culvert engineering is compared with the traditional open excavation construction method.，Degree of mechanization、Higher safety performance，Fast，The construction scope is small，No grading，And that slag discharge is less、Low noise and vibration，It also has less impact on the surrounding environment.，Have safety、Quick、Economy、Technical advantages such as environmental protection。Compare with traditional open cut method，It not only reduces the construction personnel and construction area,，But also greatly improve that construction efficiency and quality.。

“Considering that the geology of the project is mostly sandy silty clay，The surrounding groundwater is abundant，There is more silt in some sections.，If the traditional open-cut method is used for construction，There is road-occupying construction、Long construction period and the like，The project is introducedU TBMAfter，Soil body excavation can be realized、Slope support、Pipe joint assembly、Backfilling integrated construction operation，It will alleviate the crowding out of land resources in Hong Kong by municipal engineering construction.，While ensuring the smooth construction,，Does not affect the travel of Hong Kong citizens。”China Railway Equipment Co.U TBMProject manager Liu Weixiao introduced.。
