成孔偏斜

成孔偏斜是指成孔壁樁(zhuang)孔出現較大垂直偏差或彎曲。

其造成原因和處理方法主(zhu)要有：

施工現(xian)場(chang)地面(mian)軟(ruan)弱(ruo)或軟(ruan)硬不(bu)均勻，在(zai)支(zhi)架上鉆孔(kong)時，支(zhi)架的承(cheng)載(zai)力不(bu)足，發生(sheng)不(bu)均勻沉(chen)(chen)降，導致鉆桿不(bu)垂(chui)直，造成成孔(kong)偏(pian)斜。為避(bi)免(mian)事故發生(sheng)，場(chang)地必須夯實平整，軌道及枕木宜均勻著地，支(zhi)架的承(cheng)載(zai)力應(ying)滿足要(yao)求，在(zai)發生(sheng)不(bu)均勻沉(chen)(chen)降時，必須隨時調整。 850G工程資料

未做好鉆機(ji)安裝(zhuang)(zhuang)工作，是(shi)造成成孔偏斜的(de)隱(yin)患。因此要求安裝(zhuang)(zhuang)地基(ji)穩(wen)固(gu)。鉆機(ji)就位(wei)時(shi)(shi)，應使轉盤，底座水平，使天輪(lun)的(de)輪(lun)緣(yuan)、鉆桿的(de)卡盤和護(hu)筒的(de)中(zhong)心在(zai)同(tong)一垂直線(xian)上，并在(zai)鉆進過程中(zhong)防止位(wei)移(yi)，在(zai)不均勻地層中(zhong)鉆孔時(shi)(shi)，采(cai)用自重大、鉆桿剛度大的(de)鉆機(ji)。

遇到土層(ceng)呈斜狀分布(bu)或(huo)土層(ceng)中夾有(you)大的孤石(shi)或(huo)其它硬物等情形(xing)。鉆(zhan)速要(yao)加(jia)慢檔(dang)。另(ling)外(wai)安裝導(dao)正裝置也是防止孔斜的簡(jian)單有(you)效的方法。

樁底沉渣量過多

對(dui)摩擦樁(zhuang)(zhuang)來說(shuo)，由于(yu)其(qi)受力(li)機理是通過樁(zhuang)(zhuang)表(biao)面和周圍(wei)土(tu)(tu)壤之間(jian)的(de)磨擦力(li)或依(yi)附力(li)，逐漸把(ba)荷載從樁(zhuang)(zhuang)頂傳遞到周圍(wei)的(de)土(tu)(tu)體中(zhong)(zhong)，如果(guo)在設計中(zhong)(zhong)端(duan)部反力(li)不大，端(duan)部的(de)沉(chen)渣量對(dui)樁(zhuang)(zhuang)承載力(li)亦影響不大；而對(dui)于(yu)承載樁(zhuang)(zhuang)來說(shuo)，如果(guo)沉(chen)渣量過大，勢(shi)必(bi)造(zao)成樁(zhuang)(zhuang)受荷時(shi)發生大量沉(chen)降，同(tong)樣使(shi)樁(zhuang)(zhuang)的(de)承載力(li)失效，因此(ci)鉆孔灌注樁(zhuang)(zhuang)的(de)沉(chen)渣量檢(jian)查(cha)是施(shi)工(gong)控制中(zhong)(zhong)的(de)一項關鍵工(gong)作(zuo)。
