深層攪拌法

使用的(de)攪拌機械對地基(ji)中的(de)水(shui)(shui)泥和土(tu)體進行(xing)強力的(de)攪拌，從(cong)而(er)讓地基(ji)形成(cheng)一個整體，讓水(shui)(shui)泥可(ke)以(yi)形成(cheng)更(geng)加具(ju)有(you)水(shui)(shui)穩性的(de)、更(geng)加具(ju)有(you)強度的(de)土(tu)樁或者是(shi)地下連續墻(qiang)。一般情況下，這樣操作可(ke)以(yi)把地基(ji)的(de)深(shen)度處理成(cheng)8米到12米左右(you)。如果需要(yao)的(de)話，也可(ke)以(yi)使用固化劑來代替水(shui)(shui)泥。

砂石樁法

使用振動(dong)機在(zai)地基中不(bu)斷(duan)的(de)進行振動(dong)，再把(ba)套(tao)(tao)管打(da)(da)入(ru)到預定好(hao)的(de)深(shen)度中，當夯管被打(da)(da)入(ru)土(tu)(tu)中以(yi)后，就會把(ba)套(tao)(tao)管周邊的(de)土(tu)(tu)體擠(ji)壓得更加的(de)密實，然后在(zai)倒入(ru)一(yi)些砂(sha)石(shi)，把(ba)砂(sha)石(shi)排在(zai)土(tu)(tu)中，并(bing)且繼續讓(rang)振動(dong)機對(dui)砂(sha)石(shi)和土(tu)(tu)體進行擠(ji)壓，一(yi)直到成(cheng)樁為止，如(ru)此不(bu)斷(duan)的(de)反(fan)復操作，就可以(yi)形成(cheng)砂(sha)石(shi)樁了(le)。
