土樁和灰土樁

是由樁間擠密土和填(tian)夯得樁體組成(cheng)的人工(gong)“復合地(di)基”，適應于(yu)處(chu)理地(di)下(xia)水位以上，深(shen)度5—15m的濕陷性黃土或人工(gong)填(tian)土地(di)基。

土(tu)(tu)樁主要適應于(yu)：濕(shi)(shi)陷性(xing)黃(huang)土(tu)(tu)地(di)基和濕(shi)(shi)陷性(xing)；灰土(tu)(tu)樁適于(yu)：提高(gao)人(ren)工(gong)填土(tu)(tu)地(di)基的承載力。地(di)下水位以下或含水量(liang)超過25%的土(tu)(tu)，不宜采用。

深層攪拌樁

土木(mu)工程的地(di)基問(wen)題處(chu)理(li)

是利用水泥、石灰等材料作為固化劑(ji)的主劑(ji)，通(tong)過(guo)的深層攪(jiao)拌機械，在地基深處就地將軟土和固化劑(ji)（漿液或(huo)粉(fen)體）強制攪(jiao)拌，利用固化劑(ji)和軟土之間產生的一系列物理—化學反應，使軟土硬結成(cheng)具(ju)有整體性的病具(ju)有一定承載力(li)的復(fu)合地基。

深(shen)層攪拌樁適于加固各種成因的(de)飽和軟(ruan)粘土(tu)，如淤泥、淤泥質(zhi)(zhi)土(tu)、粘土(tu)、粉(fen)質(zhi)(zhi)粘土(tu)等，用于增加軟(ruan)土(tu)地(di)基的(de)承載力，減少沉降量，通過(guo)邊坡穩定性和各種坑槽工(gong)程施工(gong)時的(de)擋水帷幕。

施工(gong)前根據工(gong)程地質資料，進(jin)行室內配合(he)比試驗，結(jie)合(he)設計要求，選擇(ze)水泥摻入量，確定攪拌(ban)工(gong)藝。

鉆(zhan)孔灌(guan)注樁后注漿施(shi)工(gong)中應何控制。

一、方案審查控制

鉆孔灌注(zhu)樁后注(zhu)漿(jiang)(jiang)技術(shu)(shu)施工，施工單位除(chu)了(le)要編制(zhi)(zhi)鉆孔灌注(zhu)樁施工方案外，還需編制(zhi)(zhi)注(zhu)漿(jiang)(jiang)技術(shu)(shu)的專項施工方案，提供各種(zhong)注(zhu)漿(jiang)(jiang)參數。

后注漿技術(shu)是一種新技術(shu)，不(bu)同的(de)(de)(de)施(shi)(shi)工(gong)單位，因其(qi)人員的(de)(de)(de)技術(shu)水平、機械(xie)設備及工(gong)程(cheng)所在(zai)地工(gong)程(cheng)土物理力學性(xing)質和賦存狀態的(de)(de)(de)不(bu)同，選擇的(de)(de)(de)參數不(bu)盡(jin)相(xiang)同。因此，監(jian)理人員要依(yi)據掌(zhang)握的(de)(de)(de)施(shi)(shi)工(gong)技術(shu)知識、實際經驗(yan)、相(xiang)關資料和有(you)關規范、標(biao)準，對方案選取的(de)(de)(de)參數進行認真(zhen)的(de)(de)(de)審查。審核的(de)(de)(de)參數主要有(you)：開塞時間、開塞壓力、注漿壓力、注入水泥的(de)(de)(de)預控量(liang)。

二、鉆孔控制

鉆(zhan)孔控制主要依(yi)據相(xiang)關規范的要求進(jin)行控制。

鉆孔控制主要依據(ju)《建筑(zhu)地基基礎(chu)工程質(zhi)量施(shi)工驗收規(gui)范(fan)》《建筑(zhu)樁(zhuang)基技(ji)術規(gui)范(fan)》的相關要求和設計規(gui)范(fan)進行控制，重點控制孔深(shen)、孔徑和垂直度，了(le)解(jie)孔壁(bi)情(qing)況(kuang)，及時了(le)解(jie)孔內情(qing)況(kuang)，是(shi)否有(you)坍孔、漏水等現象(xiang)，以便(bian)在(zai)后注漿施(shi)工時采取相應(ying)的技(ji)術措施(shi)。
