6、槽然后對(duì)漏水位置進(jìn)行堵漏最后恢復(fù)保護(hù)層4、人員配置-1-5、機(jī)具配置6、滲漏水治理堵漏施工以治理結(jié)構(gòu)內(nèi)部滲漏水和結(jié)構(gòu)加固為主，與表面滲漏水治理相結(jié)合，做到標(biāo)本兼治。通過(guò)深部注水泥漿堵漏使混凝土結(jié)構(gòu)抗?jié)B能力提高，加強(qiáng)混凝土的密實(shí)性，采用注漿為主和表面開(kāi)槽封堵相結(jié)合的方案。滲漏水治理過(guò)程主要使用的材料有注漿材料（水泥漿）、槽縫堵漏材料（賽柏斯）、基面恢復(fù)材料（原建筑設(shè)計(jì)）等。南京雨田建筑工程有限公司蘇興大廈結(jié)構(gòu)底板滲漏水治理施工方案6.1各種材料的特點(diǎn)及施工方法6.1.1水泥注漿法的特點(diǎn)是：能與巖土體結(jié)合形成強(qiáng)度高
7、、滲透性小的結(jié)石體；取材容易，配方簡(jiǎn)單，操作易于掌握；無(wú)環(huán)境污染，價(jià)格便宜等。水泥注漿適用于軟粘土、粉土、新近沉積粘性土、砂土提高強(qiáng)度的加固和滲透系數(shù)大于10-2cm/s的土層的止水加固以及已建工程局部松軟地基的加固。6.1.2．機(jī)具設(shè)備灌漿設(shè)備主要是壓漿泵，其選用原則是：能滿足灌漿壓力的要求，一般為灌漿實(shí)際壓力的1.2~1.5倍；應(yīng)能滿足巖土吸漿量的要求；壓力穩(wěn)定，能保證安全可靠地運(yùn)轉(zhuǎn)；機(jī)身輕便，結(jié)構(gòu)簡(jiǎn)單，易于組裝、拆卸、搬運(yùn)。水泥壓漿泵多用泥漿泵或砂漿泵代替。國(guó)產(chǎn)泥漿泵、砂漿泵類型較多，常用于灌漿的有BW-
8、250/50型、TBW-200/40型、TBW-250/40型、NSB-100/30型泥漿泵以及100/15（C-232）型砂漿泵等。配套機(jī)具有攪拌機(jī)、灌漿管、閥門、壓力表等，此外還有鉆孔機(jī)等機(jī)具設(shè)備。6.1.3．材料要求及配合比（1）水泥用強(qiáng)度等級(jí)32.5或42.5普通硅酸鹽水泥；在特殊條件下亦可使用礦渣水泥、火山灰質(zhì)水泥或抗硫酸鹽水泥，要求新鮮無(wú)結(jié)塊。（2）水用一般飲用淡水，但不應(yīng)
