Analysis of mud-water and soil pressure balance shield construction in deep cement-rich siltstone formation
By analyzing the influencing factors of mud shield and earth pressure shield tunneling in deep water-rich strata,the relevant measures are taken to overcome the problems of the earth pressure balance shield tunneling in deep water-rich strata,such as the spouting of the screw,the equipment failure,the difficulty of slag discharge and the difficulty of slag treatment.To overcome the problems of poor circulation and mud cake formation of mud-water balanced shield in deep-buried water-rich strata.Through comparative analysis and practical verification,it is concluded that the mud-water balance shield is more advantageous in deep-buried water-rich strata.The measures taken and the selection of shield equipment under such construction conditions can be used as reference for similar projects.
