在江底修复盾构机刀盘实例

小松盾构机在广州地铁四号线小新盾构区间段穿越珠江的过程中,虽然频繁换刀,刀盘仍然磨损严重,而江底的地质状况又不具备修复刀盘的条件,本文正是针对珠江江底这种特殊的地质条件,讨论如何在江底创造敞开式开仓条件,以修复刀盘、更换刀具.

The Engineering Example of How to Repair the Cutting Wheel of the Shield Machine Below the River

During the Xiao-song shield machine drills through the Pearl River which part belongs to Xiaoxin section works of Guangzhou Metro line 4, the cutting wheel of the shield machine has worn badly though the cutters are replaced continually, however, the geology below the river can't provide the conditions with repairing the worn cutting wheel. Base of the distinguishingly geology condition below the river, the thesis analyses the works of how to create the conditions of opening the cabin to repair the cutting wheel and replace the cutters of the shield machine below the river.
