盾構二次注漿材料

1.同(tong)(tong)步(bu)注漿(jiang)。(1)灌(guan)(guan)漿(jiang)材(cai)(cai)料(liao)及配比設計(ji)。1.注漿(jiang)材(cai)(cai)料(liao)。采用(yong)水(shui)泥(ni)砂漿(jiang)作為同(tong)(tong)步(bu)灌(guan)(guan)漿(jiang)材(cai)(cai)料(liao)，具(ju)有結石率高、結石強度高、耐(nai)久性(xing)好(hao)、防止地下(xia)水(shui)沉淀的特點。2.漿(jiang)液比及主要物(wu)理力學指標(biao)。根據(ju)盾構施工(gong)(gong)經(jing)驗，計(ji)劃采用(yong)表(biao)1所示(shi)的比例進行同(tong)(tong)步(bu)灌(guan)(guan)漿(jiang)。施工(gong)(gong)中，根據(ju)地層條件、地下(xia)水(shui)條件和周邊條件，通過現(xian)場(chang)試(shi)驗優化確定。（1）凝...
