辽宁大伙房输水隧洞工程D&B3标段18＋707桩号部位地质条件较差，开挖期间突发涌水，涌水量约250～300 m3／h。涌水发生后，采取加大抽排力度、将洞室内积水排除，模筑止浆墙及灌浆的综合处理方法，模筑了ⅠⅡⅢ期混凝土及Ⅳ期钢筋混凝土止浆墙，成功地将涌水点封堵，为后续施工提供了保障。
遼寧大夥房輸水隧洞工程D&B3標段18＋707樁號部位地質條件較差，開挖期間突髮湧水，湧水量約250～300 m3／h。湧水髮生後，採取加大抽排力度、將洞室內積水排除，模築止漿牆及灌漿的綜閤處理方法，模築瞭ⅠⅡⅢ期混凝土及Ⅳ期鋼觔混凝土止漿牆，成功地將湧水點封堵，為後續施工提供瞭保障。
료녕대화방수수수동공정D&B3표단18＋707장호부위지질조건교차，개알기간돌발용수，용수량약250～300 m3／h。용수발생후，채취가대추배력도、장동실내적수배제，모축지장장급관장적종합처리방법，모축료ⅠⅡⅢ기혼응토급Ⅳ기강근혼응토지장장，성공지장용수점봉도，위후속시공제공료보장。
The geological conditions for Pile No.18 +707 of D&B3 section of tunnel engineering in Liaoning Dahuofang reservoir is poor,during the excavation water inrush occurs,outflow of about 250~300 m3/h.After the inrush,the pumping intensity is strengthened,the water in the tunnel is drained and comprehensive treatment method of moulding grouting wall and grouting are conducted, constructed I ,II,Ⅲ stage concrete and Ⅳ stage concrete reinforced concrete grout stopping wall,the surge point is closed successfully,providing a guarantee for the subsequent construction.
