成孔偏斜

成孔偏斜是指(zhi)成孔壁(bi)樁孔出(chu)現較大(da)垂(chui)直偏差(cha)或(huo)彎曲。

其造成原因和處理方法主要有(you)：

 施工(gong)(gong)現場(chang)地(di)面軟(ruan)弱或軟(ruan)硬不均(jun)勻(yun)，在(zai)支(zhi)架上鉆孔時，支(zhi)架的承(cheng)載(zai)力不足(zu)，發生不均(jun)勻(yun)沉降，導致鉆桿不垂直，造成成孔偏(pian)斜。為避免事故發生，場(chang)地(di)必(bi)須(xu)夯實平整，山(shan)西擠密樁基施工(gong)(gong)，軌道及枕木宜均(jun)勻(yun)著地(di)，支(zhi)架的承(cheng)載(zai)力應滿(man)足(zu)要求，在(zai)發生不均(jun)勻(yun)沉降時，必(bi)須(xu)隨(sui)時調整。 850G工(gong)(gong)程資(zi)料

未做好鉆(zhan)(zhan)機安裝(zhuang)工作，是造成成孔偏(pian)斜的(de)隱患。因此(ci)要求安裝(zhuang)地(di)基穩(wen)固。鉆(zhan)(zhan)機就(jiu)位時(shi)，應使轉盤(pan)，底座水平，使天輪(lun)的(de)輪(lun)緣、鉆(zhan)(zhan)桿的(de)卡盤(pan)和護筒的(de)中(zhong)心在同一(yi)垂直線上，并在鉆(zhan)(zhan)進(jin)過程中(zhong)防止位移，在不均勻地(di)層中(zhong)鉆(zhan)(zhan)孔時(shi)，采用(yong)自重大(da)、鉆(zhan)(zhan)桿剛度大(da)的(de)鉆(zhan)(zhan)機。

遇到土(tu)層呈(cheng)斜狀(zhuang)分(fen)布(bu)或土(tu)層中夾有(you)大的孤石(shi)或其(qi)它硬物等情形。鉆速(su)要加(jia)慢檔。另外安裝導正裝置也是防止(zhi)孔斜的簡(jian)單有(you)效的方法(fa)。

樁底沉渣量過多

對(dui)摩擦(ca)樁(zhuang)(zhuang)(zhuang)來(lai)說，由于(yu)其受力機(ji)理是(shi)通過(guo)樁(zhuang)(zhuang)(zhuang)表面和(he)周圍(wei)(wei)土(tu)壤之間的(de)磨擦(ca)力或依附力，逐漸把荷載(zai)從樁(zhuang)(zhuang)(zhuang)頂傳遞到周圍(wei)(wei)的(de)土(tu)體中(zhong)，如果(guo)在設計中(zhong)端部(bu)反力不(bu)大(da)，端部(bu)的(de)沉渣(zha)量對(dui)樁(zhuang)(zhuang)(zhuang)承(cheng)(cheng)載(zai)力亦影響不(bu)大(da)；而對(dui)于(yu)承(cheng)(cheng)載(zai)樁(zhuang)(zhuang)(zhuang)來(lai)說，如果(guo)沉渣(zha)量過(guo)大(da)，勢必造成樁(zhuang)(zhuang)(zhuang)受荷時(shi)發生大(da)量沉降，同樣使(shi)樁(zhuang)(zhuang)(zhuang)的(de)承(cheng)(cheng)載(zai)力失效，因此鉆孔灌(guan)注樁(zhuang)(zhuang)(zhuang)的(de)沉渣(zha)量檢(jian)查是(shi)施(shi)工控制(zhi)中(zhong)的(de)一項關鍵工作(zuo)。

滿夯(hang)跟強夯(hang)施工有什么(me)不一樣的(de)地方(fang)呢？

滿夯(hang)是(shi)強夯(hang)施工地(di)基(ji)處理中(zhong)的在其(qi)中(zhong)一(yi)種加(jia)工工藝(yi)，一(yi)般來說滿夯(hang)的使用(yong)大(da)概可依照下邊(bian)的步驟開展。

1、主復夯(hang)所有工(gong)程施工(gong)完畢以(yi)后，大家(jia)會(hui)對不一樣土層開展區別，區分后的土層靜(jing)養(yang)時(shi)間也(ye)會(hui)不一樣，須直到孔(kong)隙度中的水清(qing)除后，才(cai)可以(yi)推行滿夯(hang)施工(gong)技術。

2、滿(man)(man)夯(hang)(hang)關(guan)鍵(jian)功能于表(biao)層(ceng)，這兒的(de)表(biao)層(ceng)的(de)含意關(guan)鍵(jian)指：主夯(hang)(hang)擊點(dian)高(gao)電子能級夯(hang)(hang)擊震(zhen)動造成松脫的(de)地表(biao)層(ceng)土。此外在開展滿(man)(man)夯(hang)(hang)加工(gong)工(gong)藝進行流程中(zhong)，其夯(hang)(hang)擊能通常是主夯(hang)(hang)點(dian)夯(hang)(hang)擊能的(de)二分之一。除此之外通過(guo)滿(man)(man)夯(hang)(hang)后的(de)地表(biao)要加一遍(bian)輾壓。

3、滿(man)夯的(de)(de)工(gong)(gong)程(cheng)(cheng)施(shi)工(gong)(gong)通常采用四(si)分之(zhi)一(yi)的(de)(de)錘徑(jing)，開展(zhan)雙重(zhong)鋼筋搭(da)接。夯錘夯擊的(de)(de)次數、每一(yi)次點一(yi)下的(de)(de)數目及其(qi)鋼筋搭(da)接都應當依(yi)照試夯明確的(de)(de)技術參(can)數來工(gong)(gong)程(cheng)(cheng)施(shi)工(gong)(gong)，需注意的(de)(de)是不可(ke)以發生漏(lou)夯的(de)(de)狀況(kuang)。

滿夯(hang)是(shi)對回填土(tu)后的(de)地土(tu)壤(rang)層(ceng)采用聯合分布的(de)夯(hang)實(shi)(shi)，并(bing)且是(shi)不可忽略的(de)。因(yin)此它主(zhu)要(yao)(yao)是(shi)對夯(hang)實(shi)(shi)品(pin)質的(de)嚴格管理。殊不知與眾不同的(de)是(shi)強夯(hang)地基主(zhu)要(yao)(yao)是(shi)應用大(da)落距、大(da)凈重(zhong)的(de)夯(hang)錘，來夯(hang)實(shi)(shi)回填，這也是(shi)一般夯(hang)實(shi)(shi)加工(gong)工(gong)藝(yi)沒(mei)法或難以做到的(de)實(shi)(shi)際效(xiao)果。

滿夯(hang)(hang)的動(dong)(dong)能較(jiao)低，應用低動(dong)(dong)能夯(hang)(hang)錘夯(hang)(hang)擊，用以表層。此(ci)外落(luo)夯(hang)(hang)點中間(jian)互相(xiang)密切排序，不(bu)容易存有(you)空隙。每擊夯(hang)(hang)點的間(jian)距距離為零。它規定互壓或(huo)鋼筋搭接錘印，少(shao)夯(hang)(hang)很多遍。

強夯工程時(shi)遇到(dao)塌(ta)陷問(wen)題應該如何處理(li)？

 強(qiang)(qiang)夯(hang)施工的(de)過程(cheng)中會遇許多(duo)的(de)問(wen)(wen)題(ti)，強(qiang)(qiang)夯(hang)施工團隊都會根據具體情況找到到相對應的(de)預防(fang)措施和解決方案(an)，今(jin)天跟大(da)家分(fen)享(xiang)的(de)一下如(ru)(ru)果(guo)在強(qiang)(qiang)夯(hang)過程(cheng)中遇到塌陷問(wen)(wen)題(ti)應當如(ru)(ru)何快(kuai)速(su)找到原因并進行解決。可能會出現的(de)原因以及應對處理方法：

 1、中控式塌(ta)陷

強夯施工

 一(yi)(yi)般造(zao)成這(zhe)(zhe)種原(yuan)因的塌陷多(duo)半是個本身的地(di)質是有關(guan)系的，例如一(yi)(yi)些丘陵地(di)勢，這(zhe)(zhe)類地(di)形(xing)的土(tu)層(ceng)比較疏(shu)松，切雨水(shui)較多(duo)，經過多(duo)年的雨水(shui)沖刷，表面上看(kan)見起來雖然沒什么變化(hua)，但(dan)是地(di)層(ceng)里部(bu)(bu)會(hui)有部(bu)(bu)分的空洞部(bu)(bu)分，在此上進行強夯施工(gong)后，土(tu)質就(jiu)會(hui)造(zao)成坍塌，這(zhe)(zhe)種塌陷解(jie)決辦法也非(fei)常的簡單，前期做好(hao)測量，經過施工(gong)后回(hui)填土(tu)進行解(jie)決就(jiu)可(ke)以了。

 2 、水流沖(chong)刷(shua)塌(ta)陷

 這(zhe)個(ge)處理(li)辦法很簡單，但是速度要快。盡快找到水流的就(jiu)可以的，截住(zhu)后(hou)積(ji)水用水泵抽(chou)掉就(jiu)行。

 3 、地質復雜

 這(zhe)種情況其(qi)實也(ye)是(shi)比較的多(duo)見(jian)，例(li)如一(yi)些(xie)碎石地(di)帶，中間摻雜著一(yi)些(xie)大塊的石頭，需要去除(chu)石頭之后再進行強夯。這(zhe)樣也(ye)會(hui)造成一(yi)定(ding)的塌陷。處理方式(shi)就是(shi)回(hui)填土(tu)的時(shi)候盡量(liang)使用一(yi)些(xie)和本地(di)土(tu)質接近(jin)的方式(shi)進行回(hui)填。
