地基處理的方法

1、 換填法

假如地(di)基(ji)(ji)的(de)持力(li)層(ceng)(ceng)比較軟弱，沒有辦法(fa)滿足建(jian)筑物(wu)對地(di)基(ji)(ji)的(de)要求的(de)時候(hou)，一般(ban)都會(hui)使用(yong)換土墊層(ceng)(ceng)的(de)方法(fa)來處理地(di)基(ji)(ji)。也就是在(zai)一定(ding)的(de)范圍內(nei)把(ba)地(di)基(ji)(ji)的(de)土層(ceng)(ceng)挖空(kong)掉(diao)，山西灰土擠(ji)密樁施(shi)工隊，然后在(zai)挖空(kong)位(wei)置填滿強(qiang)度更(geng)大的(de)砂子、泥土、碎(sui)石等等，并(bing)且會(hui)把(ba)這些東西夯實(shi)得非常密實(shi)。

2、 預壓法

在(zai)建造房屋之前(qian)，先在(zai)施工(gong)場(chang)地(di)上施加或(huo)者是分級施加和(he)地(di)基(ji)(ji)相當(dang)的荷載，讓(rang)(rang)地(di)基(ji)(ji)土(tu)層空隙中的水被擠壓出來，讓(rang)(rang)土(tu)層空隙變(bian)得(de)更小，讓(rang)(rang)地(di)基(ji)(ji)土(tu)層變(bian)得(de)更加的密實(shi)，從而把地(di)基(ji)(ji)的承載能力(li)和(he)穩定性(xing)變(bian)得(de)更強。

3、 強夯法

把幾十噸(dun)的(de)(de)重錘從高(gao)處重重的(de)(de)落在地基(ji)上，如此反復操(cao)作，不斷的(de)(de)對(dui)地面進行強(qiang)力的(de)(de)夯擊，讓地基(ji)直(zhi)接被夯實得非常密實。一(yi)般情況下，經過(guo)強(qiang)力夯實的(de)(de)地基(ji)可以提高(gao)2倍(bei)到(dao)5倍(bei)左右(you)的(de)(de)承載力，而壓縮性則會(hui)被降低到(dao)200%到(dao)500%之間，地基(ji)深度則會(hui)被下降10米左右(you)。

4、振沖法

利用(yong)振(zhen)(zhen)動(dong)器不(bu)斷(duan)的在地(di)基(ji)中進行(xing)加水(shui)和(he)振(zhen)(zhen)動(dong)，讓(rang)土(tu)層空隙變得(de)更(geng)小，讓(rang)地(di)基(ji)土(tu)層變得(de)更(geng)加的密實，從而改(gai)善地(di)基(ji)狀態，讓(rang)地(di)基(ji)可以(yi)滿足建筑(zhu)物對地(di)基(ji)的施工(gong)要(yao)求。振(zhen)(zhen)沖法(fa)全稱叫做振(zhen)(zhen)動(dong)水(shui)沖擊法(fa)，一般(ban)可以(yi)被分為振(zhen)(zhen)沖置換法(fa)和(he)振(zhen)(zhen)沖密實法(fa)兩種，大家可以(yi)根據地(di)基(ji)土(tu)層的不(bu)同來進行(xing)選擇。

混凝土(tu)澆注時導(dao)管進泥

產生原因：

1.初灌混凝土數量不足。

2.導(dao)管底距(ju)槽(cao)底間距(ju)過大。

3.導管插入混凝土內深度不足。

4.提導管(guan)(guan)過度，泥(ni)漿擠入管(guan)(guan)內。

預防措施(shi)和處理(li)方法(fa)：

預(yu)防：首批混凝(ning)土(tu)應經計算(suan)，保(bao)持(chi)足夠數量(liang)，導(dao)管(guan)口離槽底間(jian)距(ju)保(bao)持(chi)不小于1.5D（D為導(dao)管(guan)直徑），導(dao)管(guan)插入混凝(ning)土(tu)深度保(bao)持(chi)不小于1.5m；測定混凝(ning)土(tu)上升(sheng)面，確定高度后(hou)再(zai)距(ju)此(ci)提拔導(dao)管(guan)。

處理：如槽(cao)底混凝(ning)(ning)土(tu)深度小(xiao)于0.5m，可重新(xin)放隔水塞澆(jiao)混凝(ning)(ning)土(tu)，否則(ze)應(ying)將(jiang)導(dao)管提出，將(jiang)槽(cao)底混凝(ning)(ning)土(tu)用(yong)空氣吸泥機清出，重新(xin)澆(jiao)筑混凝(ning)(ning)土(tu)，或改用(yong)帶活底蓋導(dao)管插入(ru)混凝(ning)(ning)土(tu)內，重新(xin)澆(jiao)混凝(ning)(ning)土(tu)。

強夯(hang)法處理(li)。強夯(hang)法是利用重錘自由(you)落(luo)下的(de)(de)(de)巨大沖力能所產(chan)沖擊波反(fan)復夯(hang)擊地基(ji)土(tu)(tu)，將夯(hang)面以下一定深(shen)度地土(tu)(tu)層(ceng)夯(hang)實，以提高地基(ji)的(de)(de)(de)承載力和土(tu)(tu)體的(de)(de)(de)穩定性，降低(di)壓(ya)縮性。由(you)于(yu)夯(hang)擊能力大，加固深(shen)度也大。對(dui)于(yu)一般(ban)的(de)(de)(de)軟土(tu)(tu)地基(ji)加固有(you)著良好(hao)的(de)(de)(de)效果。現(xian)在常用的(de)(de)(de)強夯(hang)技術加固軟土(tu)(tu)地基(ji)的(de)(de)(de)方法有(you):擠密碎(sui)石樁(zhuang)加夯(hang)法、砂(sha)樁(zhuang)加夯(hang)法、真空(kong)/堆載預壓(ya)加強夯(hang)、強夯(hang)碎(sui)石墩。
