土樁和灰土樁

是由樁間擠(ji)密土(tu)和(he)填夯得(de)樁體組成的人工“復合(he)地基”，適應于處(chu)理(li)地下水位以上，深度(du)5—15m的濕陷(xian)性黃土(tu)或人工填土(tu)地基。

土(tu)樁主要適應于：濕陷性(xing)(xing)黃(huang)土(tu)地基和濕陷性(xing)(xing)；灰土(tu)樁適于：提高人工填土(tu)地基的承載力。地下(xia)水位以下(xia)或含水量超過25%的土(tu)，不宜采用。

深層攪拌樁

土木工程的地基(ji)問題處(chu)理

灌注樁(zhuang)超聲成孔檢(jian)測的重要性

灌注(zhu)樁(zhuang)(zhuang)屬于建(jian)筑(zhu)(zhu)(zhu)(zhu)結構(gou)中常用的(de)(de)(de)(de)樁(zhuang)(zhuang)基(ji)(ji)模(mo)式(shi)，其(qi)將(jiang)頂部(bu)構(gou)造的(de)(de)(de)(de)荷載傳(chuan)送入深層穩固的(de)(de)(de)(de)土層和巖層，降低建(jian)筑(zhu)(zhu)(zhu)(zhu)結構(gou)的(de)(de)(de)(de)不均勻下沉。灌注(zhu)樁(zhuang)(zhuang)的(de)(de)(de)(de)建(jian)設(she)包括成(cheng)孔(kong)(kong)與成(cheng)樁(zhuang)(zhuang)兩類，其(qi)中，成(cheng)孔(kong)(kong)屬于灌注(zhu)樁(zhuang)(zhuang)建(jian)設(she)的(de)(de)(de)(de)環節。成(cheng)孔(kong)(kong)施工因為(wei)是在(zai)地下、水(shui)中完(wan)成(cheng)，質量難以控制(zhi)，復(fu)雜的(de)(de)(de)(de)地質環境或施工過程的(de)(de)(de)(de)失誤均會引起塌(ta)孔(kong)(kong)、縮孔(kong)(kong)、樁(zhuang)(zhuang)孔(kong)(kong)傾斜、沉渣(zha)太厚等情況(kuang)。成(cheng)孔(kong)(kong)性能的(de)(de)(de)(de)優劣(lie)直接關系著混(hun)凝(ning)土澆筑(zhu)(zhu)(zhu)(zhu)后的(de)(de)(de)(de)成(cheng)孔(kong)(kong)效(xiao)果：樁(zhuang)(zhuang)孔(kong)(kong)徑較小，就(jiu)導致樁(zhuang)(zhuang)頂部(bu)承(cheng)重降低，整樁(zhuang)(zhuang)性能下降；樁(zhuang)(zhuang)孔(kong)(kong)擴徑會造成(cheng)成(cheng)樁(zhuang)(zhuang)頂部(bu)側阻(zu)力(li)加大，而(er)(er)底(di)部(bu)側阻(zu)力(li)無(wu)法發(fa)揮，而(er)(er)且單樁(zhuang)(zhuang)的(de)(de)(de)(de)混(hun)凝(ning)土澆筑(zhu)(zhu)(zhu)(zhu)量增多，成(cheng)本增加；樁(zhuang)(zhuang)孔(kong)(kong)傾斜轉變了(le)樁(zhuang)(zhuang)豎(shu)向性能，制(zhi)約著樁(zhuang)(zhuang)基(ji)(ji)承(cheng)載力(li)的(de)(de)(de)(de)發(fa)揮，而(er)(er)且孔(kong)(kong)斜還易出現吊鋼(gang)筋籠不易、塌(ta)孔(kong)(kong)、鋼(gang)筋防護層厚度不夠等情況(kuang)；樁(zhuang)(zhuang)底(di)沉渣(zha)太厚令樁(zhuang)(zhuang)長(chang)縮減，限制(zhi)樁(zhuang)(zhuang)頂端承(cheng)重水(shui)平(ping)。所以，在(zai)混(hun)凝(ning)土澆筑(zhu)(zhu)(zhu)(zhu)前開(kai)展灌注(zhu)樁(zhuang)(zhuang)成(cheng)孔(kong)(kong)質檢工作對成(cheng)樁(zhuang)(zhuang)質量非常重要。

鉆孔灌(guan)注樁后注漿施工中應何控制。

一、方案審查控制

鉆孔(kong)灌(guan)注(zhu)樁(zhuang)后注(zhu)漿(jiang)技術施(shi)工(gong)，施(shi)工(gong)單位除(chu)了要編(bian)制鉆孔(kong)灌(guan)注(zhu)樁(zhuang)施(shi)工(gong)方案(an)(an)外，還需編(bian)制注(zhu)漿(jiang)技術的專項施(shi)工(gong)方案(an)(an)，提(ti)供(gong)各種注(zhu)漿(jiang)參數(shu)。

后注漿技(ji)(ji)術(shu)(shu)是一(yi)種新技(ji)(ji)術(shu)(shu)，不同的(de)(de)施(shi)工(gong)單位，因(yin)(yin)其人員(yuan)的(de)(de)技(ji)(ji)術(shu)(shu)水平、機械設備及(ji)工(gong)程(cheng)所在(zai)地(di)工(gong)程(cheng)土物(wu)理(li)力學性質和(he)賦存狀態的(de)(de)不同，山(shan)(shan)西擠密(mi)樁基(ji)施(shi)工(gong)，選(xuan)擇的(de)(de)參數不盡相同。因(yin)(yin)此，山(shan)(shan)西擠密(mi)樁基(ji)施(shi)工(gong)報價，監理(li)人員(yuan)要依據掌握(wo)的(de)(de)施(shi)工(gong)技(ji)(ji)術(shu)(shu)知識、實際(ji)經驗、相關(guan)資料和(he)有關(guan)規范、標(biao)準(zhun)，對方案選(xuan)取的(de)(de)參數進行認真的(de)(de)審查。審核的(de)(de)參數主要有：開塞(sai)(sai)時間、開塞(sai)(sai)壓力、注漿壓力、注入水泥(ni)的(de)(de)預控量。

二、鉆孔控制

鉆(zhan)孔控(kong)制(zhi)主要(yao)依據相關規范的要(yao)求進行控(kong)制(zhi)。

鉆孔(kong)控制主(zhu)要(yao)依據《建筑(zhu)地基(ji)基(ji)礎工(gong)程質(zhi)量(liang)施(shi)(shi)工(gong)驗收規范》《建筑(zhu)樁基(ji)技(ji)術(shu)規范》的(de)相(xiang)關要(yao)求和(he)設計規范進(jin)行控制，重(zhong)點控制孔(kong)深、孔(kong)徑(jing)和(he)垂直(zhi)度，了解(jie)孔(kong)壁情況(kuang)，及時了解(jie)孔(kong)內情況(kuang)，是否有坍孔(kong)、漏水等現象，以便在后注漿(jiang)施(shi)(shi)工(gong)時采(cai)取相(xiang)應的(de)技(ji)術(shu)措施(shi)(shi)。
