成孔偏斜

成孔(kong)偏斜是指成孔(kong)壁(bi)樁孔(kong)出(chu)現較大垂直偏差或彎曲。

其(qi)造成原因和處理方法主(zhu)要有：

 施(shi)工(gong)現場地(di)面軟(ruan)弱(ruo)或(huo)軟(ruan)硬不(bu)(bu)均(jun)勻(yun)，在支架(jia)上鉆孔時，支架(jia)的(de)承載力不(bu)(bu)足(zu)，發生不(bu)(bu)均(jun)勻(yun)沉降(jiang)，山西擠(ji)密樁基施(shi)工(gong)聯系方(fang)式，導致鉆桿不(bu)(bu)垂(chui)直，造成成孔偏(pian)斜(xie)。為避免事(shi)故(gu)發生，場地(di)必須(xu)夯實平整(zheng)，軌道及枕木宜(yi)均(jun)勻(yun)著地(di)，支架(jia)的(de)承載力應(ying)滿(man)足(zu)要求，在發生不(bu)(bu)均(jun)勻(yun)沉降(jiang)時，必須(xu)隨時調整(zheng)。 850G工(gong)程(cheng)資(zi)料(liao)

未(wei)做好鉆機(ji)安裝工(gong)作，是造成(cheng)成(cheng)孔偏斜的(de)隱患。因此要(yao)求安裝地基(ji)穩(wen)固。鉆機(ji)就位時，應使轉盤，底座水平，使天輪的(de)輪緣、鉆桿的(de)卡盤和護筒的(de)中心在同一(yi)垂(chui)直線上，并在鉆進(jin)過程(cheng)中防止位移，在不均勻地層中鉆孔時，山西擠(ji)密樁基(ji)施工(gong)隊(dui)，采用自(zi)重(zhong)大(da)、鉆桿剛(gang)度大(da)的(de)鉆機(ji)。

遇(yu)到土層呈斜狀分布或(huo)土層中夾有大的孤(gu)石(shi)或(huo)其它硬物等情形。鉆(zhan)速要加慢檔(dang)。另外安裝導正裝置(zhi)也是防(fang)止(zhi)孔斜的簡單(dan)有效的方法(fa)。

樁底沉渣量過多

對(dui)(dui)摩擦樁(zhuang)來說，由(you)于其(qi)受力(li)機理(li)是通過(guo)樁(zhuang)表面和周(zhou)圍土(tu)壤之間(jian)的(de)磨(mo)擦力(li)或依附力(li)，逐(zhu)漸把荷(he)載從樁(zhuang)頂(ding)傳遞到(dao)周(zhou)圍的(de)土(tu)體中，如果在設計中端(duan)部反(fan)力(li)不大(da)，端(duan)部的(de)沉(chen)渣量(liang)對(dui)(dui)樁(zhuang)承(cheng)載力(li)亦影響不大(da)；而對(dui)(dui)于承(cheng)載樁(zhuang)來說，如果沉(chen)渣量(liang)過(guo)大(da)，勢必造成樁(zhuang)受荷(he)時發生大(da)量(liang)沉(chen)降，同樣使(shi)樁(zhuang)的(de)承(cheng)載力(li)失(shi)效(xiao)，因此鉆孔灌注樁(zhuang)的(de)沉(chen)渣量(liang)檢(jian)查是施工(gong)控(kong)制中的(de)一(yi)項(xiang)關鍵工(gong)作。

水(shui)泥(ni)土(tu)(tu)(tu)粉噴樁(zhuang)法。粉噴樁(zhuang)與周圍的(de)(de)土(tu)(tu)(tu)體(ti)形(xing)成復合地基(ji)(ji)，與土(tu)(tu)(tu)體(ti)結合緊密，承載(zai)(zai)能力較大(da)，其樁(zhuang)體(ti)上(shang)(shang)存在應力集(ji)中現(xian)象(xiang)，大(da)部分荷載(zai)(zai)由樁(zhuang)體(ti)承擔(dan)，樁(zhuang)間(jian)土(tu)(tu)(tu)上(shang)(shang)的(de)(de)應力相應的(de)(de)減(jian)少，使復合地基(ji)(ji)承載(zai)(zai)力較原土(tu)(tu)(tu)層(ceng)有(you)所(suo)提高(gao)(gao)，沉降量(liang)有(you)所(suo)降低。采用(yong)該法加固軟土(tu)(tu)(tu)地基(ji)(ji)時，水(shui)泥(ni)粉具(ju)有(you)較大(da)的(de)(de)吸水(shui)，發熱(re)和膨脹作(zuo)用(yong)，對樁(zhuang)間(jian)土(tu)(tu)(tu)起塑料板材排水(shui)板到一定的(de)(de)加固作(zuo)用(yong)，同樣提高(gao)(gao)復合地基(ji)(ji)的(de)(de)強度(du)。

在利用水泥(ni)土(tu)粉(fen)噴樁(zhuang)加(jia)固軟土(tu)地基時，需考慮各種因(yin)素對加(jia)固強度(du)的(de)影響(xiang):①要以水泥(ni)粉(fen)為(wei)(wei)加(jia)固料，其強度(du);②攪拌(ban)時間(jian)(jian)為(wei)(wei)2min時就(jiu)可(ke)以達到的(de)攪拌(ban)效(xiao)果，若攪拌(ban)時間(jian)(jian)太長(chang)，強度(du)會有所(suo)降低，若攪拌(ban)的(de)時間(jian)(jian)未達到2min時，強度(du)會很低;③置換(huan)率(lv)越(yue)高，強度(du)越(yue)高，而隨著齡期的(de)增加(jia)，強度(du)大致呈(cheng)線(xian)塑料排水板(ban)的(de)價格性增加(jia);④當含水量為(wei)(wei)某(mou)值時，樁(zhuang)體(ti)的(de)強度(du)達到，一(yi)般(ban)樁(zhuang)體(ti)的(de)需水量為(wei)(wei)4kg/m。
