【摘要】：分析了影響泥水平衡盾構(gòu)穿越軟弱地層掘進(jìn)速度的因素,通過調(diào)整黏土段的掘進(jìn)參數(shù)和泥漿性能,改善泥漿攜渣能力,加快了黏土段掘進(jìn)速度,給出了改善出渣和壓力波動的主要技術(shù)措施。通過不斷調(diào)整盾構(gòu)機(jī)刀盤轉(zhuǎn)速、掘進(jìn)速度、推力及扭矩等運行參數(shù),順利通過砂礫層。加強(qiáng)泥漿比重和泥水循環(huán)的調(diào)整,避免了堵倉、堵泵或者泥水循環(huán)管路堵塞情況的發(fā)生,形成了泥水平衡盾構(gòu)穿越軟弱地層施工的關(guān)鍵成套技術(shù),實現(xiàn)了軟巖條件下泥水平衡盾構(gòu)長距離快速掘進(jìn)。
[Abstract]:This paper analyzes the factors that affect the tunneling speed of mud water balance shield tunneling through weak strata. By adjusting the tunneling parameters and mud properties of clay section, the mud slag carrying capacity is improved, and the driving speed of clay section is accelerated. The main technical measures to improve slag production and pressure fluctuation are given. By adjusting the running parameters of shield machine, such as rotating speed, driving speed, thrust and torque of shield machine, the sand gravel layer is passed smoothly. To strengthen the adjustment of mud specific gravity and muddy water circulation, to avoid blockage of silo, pump or mud-water circulation pipeline, and to form the key complete set of technology for mud-water balance shield tunneling through weak strata. The long distance rapid tunneling of mud water balance shield under soft rock condition is realized.
