為處理好孔壁坍塌、埋鉆的問題，要做(zuo)到以下幾點：

做好泥漿制備工作。

土(tu)質松散(san)、護(hu)(hu)(hu)(hu)筒(tong)周(zhou)(zhou)圍(wei)未用粘土(tu)緊密填封以(yi)及護(hu)(hu)(hu)(hu)筒(tong)內水(shui)(shui)位(wei)不高(gao)以(yi)及鉆進速度過(guo)快(kuai)、空鉆時(shi)間(jian)過(guo)長、成孔(kong)后待灌時(shi)間(jian)過(guo)長和(he)(he)灌注時(shi)間(jian)過(guo)長都會會引起孔(kong)壁坍(tan)陷。因此，在松散(san)易坍(tan)的(de)(de)土(tu)層中，要(yao)適當埋(mai)深護(hu)(hu)(hu)(hu)筒(tong)，用粘土(tu)密實填封護(hu)(hu)(hu)(hu)筒(tong)四周(zhou)(zhou)，使(shi)用的(de)(de)泥漿，提高(gao)泥漿的(de)(de)比重和(he)(he)粘度，保持護(hu)(hu)(hu)(hu)筒(tong)內泥漿水(shui)(shui)位(wei)高(gao)于(yu)地下水(shui)(shui)位(wei)。

當遇到小(xiao)溶洞或裂縫時，可能(neng)發生孔(kong)內泥漿(jiang)均勻緩慢(man)下降的現象。這時，山西素土(tu)擠密樁施工聯系方式，可采用在泥漿(jiang)中加適(shi)量水(shui)泥，增大(da)泥漿(jiang)比重及其護壁效(xiao)果。

縮頸，即孔(kong)(kong)小(xiao)于設(she)計(ji)孔(kong)(kong)徑，是鉆孔(kong)(kong)灌注樁(zhuang)常見的質量問(wen)題。

解決(jue)縮頸問題要針(zhen)對其產生的(de)原因，找(zhao)到正確的(de)處理方法：

縮頸的(de)主要原(yuan)因是由于樁(zhuang)周土體(ti)在樁(zhuang)體(ti)澆(jiao)注(zhu)過程中產(chan)生的(de)膨脹造(zao)成。針對這種情況，應采(cai)用泥漿，降低失水量。

當軟土(tu)層(ceng)受(shou)地下水(shui)(shui)影響和周邊車輛(liang)振動(dong)時(shi)，也容易發生縮頸。這(zhe)時(shi)，可(ke)在軟塑土(tu)地層(ceng)采用失水(shui)(shui)率小的(de)泥(ni)漿護壁，山西素土(tu)擠(ji)密樁(zhuang)施(shi)工設備租賃，降低失水(shui)(shui)量。

因鉆(zhan)錘磨損原因造成的縮頸，應及(ji)時(shi)焊(han)補(bu)鉆(zhan)錘，山西素土擠(ji)密樁(zhuang)施工，或(huo)在其外側焊(han)接(jie)一定數量的合金(jin)刀片，在鉆(zhan)進或(huo)起鉆(zhan)時(shi)起到掃孔作用。

強夯工(gong)程施工(gong)法在地(di)基加固(gu)中的(de)運用！

強(qiang)(qiang)夯工(gong)程(cheng)施工(gong)法(fa)解決路基是(shi)(shi)籍(ji)重(zhong)錘式從高空隨(sui)意落下來(lai)給路基土(tu)(tu)(tu)(tu)施加撞擊力和(he)(he)震動，進(jin)而做(zuo)到提(ti)升路基土(tu)(tu)(tu)(tu)的(de)抗(kang)壓強(qiang)(qiang)度并(bing)減少其膨脹性(xing)，還能(neng)改(gai)進(jin)其抗(kang)震動汽化的(de)功能(neng)和(he)(he)清除土(tu)(tu)(tu)(tu)的(de)濕陷性(xing)。強(qiang)(qiang)夯法(fa)在進(jin)行時僅用(yong)以結(jie)構加固(gu)沙子(zi)和(he)(he)砂土(tu)(tu)(tu)(tu)路基。通過幾十(shi)年(nian)來(lai)的(de)運(yun)用(yong)與發展趨勢，它已適用(yong)從砂礫到粘性(xing)土(tu)(tu)(tu)(tu)的(de)各(ge)種路基土(tu)(tu)(tu)(tu)，這主要(yao)是(shi)(shi)由工(gong)程(cheng)施工(gong)方式 的(de)完善(shan)和(he)(he)排水管道標準(zhun)的(de)改(gai)進(jin)。

強夯(hang)法(fa)又稱(cheng)之為(wei)(wei)驅(qu)動力預壓法(fa)或(huo)驅(qu)動力夯(hang)實法(fa)。這類辦法(fa)是不斷將重錘式(shi)(一般(ban)為(wei)(wei)10～40t)提及高空使其隨意落下來(一般(ban)落距為(wei)(wei)10～40m)夯(hang)擊路基，進而使路基的(de)硬度提升、膨脹(zhang)性獲得減少的(de)方(fang)式(shi)。強夯(hang)法(fa)因為(wei)(wei)具備結構(gou)加(jia)固效果非常的(de)好、適用土的(de)分類廣、機器設備簡易(yi)、工(gong)程施(shi)工(gong)便捷、節約人(ren)力、工(gong)期(qi)短、節省原材料、工(gong)程施(shi)工(gong)文(wen)明行為(wei)(wei)和工(gong)程施(shi)工(gong)花費劣等(deng)優勢，迅(xun)速就推(tui)廣到各地區。

強夯(hang)工程施工法適用解決砂土(tu)(tu)(tu)、碎(sui)石土(tu)(tu)(tu)、砂土(tu)(tu)(tu)、粘性(xing)土(tu)(tu)(tu)、濕陷性(xing)黃土(tu)(tu)(tu)和(he)素填(tian)土(tu)(tu)(tu)等(deng)路基(ji)(ji)，它(ta)不(bu)但能(neng)提升路基(ji)(ji)的抗壓強度、減少其膨脹(zhang)性(xing)、還能(neng)改進其抗震(zhen)動汽化的功能(neng)和(he)清除土(tu)(tu)(tu)的濕陷性(xing)，因此還常見于解決可液化碎(sui)石土(tu)(tu)(tu)路基(ji)(ji)和(he)濕陷性(xing)路基(ji)(ji)等(deng)。強夯(hang)法針對(dui)(dui)對(dui)(dui)比度較高(gao)的粘性(xing)土(tu)(tu)(tu)，一般來說(shuo)解決作用不(bu)顯著，尤其是污(wu)泥(ni)和(he)淤(yu)泥(ni)質土(tu)(tu)(tu)地資源(yuan)(yuan)基(ji)(ji)，解決實(shi)際效果更差。因而針對(dui)(dui)污(wu)泥(ni)質土(tu)(tu)(tu)地資源(yuan)(yuan)基(ji)(ji)應慎(shen)重采用或采取別的方(fang)式。
