強夯工程時遇(yu)到(dao)塌(ta)陷問(wen)題應該(gai)如何處理(li)？

強夯施工的(de)過程中(zhong)會(hui)遇許多的(de)問題，強夯施工團(tuan)隊都會(hui)根據具體情況找到到相對應的(de)預防措(cuo)施和(he)解(jie)決(jue)方案，今天跟(gen)大家分享的(de)一下如果在(zai)強夯過程中(zhong)遇到塌陷問題應當如何快(kuai)速(su)找到原因并進(jin)行解(jie)決(jue)。可能會(hui)出(chu)現的(de)原因以及應對處理方法：

1、中控式塌陷

強夯施工

一(yi)般造成這(zhe)種(zhong)原因(yin)的塌陷多(duo)半(ban)是(shi)個本身(shen)的地質是(shi)有關(guan)系的，例如一(yi)些丘陵地勢，這(zhe)類地形的土(tu)層比較(jiao)疏松，切雨水較(jiao)多(duo)，經過多(duo)年的雨水沖刷，表面上(shang)看見起來雖然沒(mei)什么(me)變化，但是(shi)地層里(li)部會有部分(fen)的空洞部分(fen)，在(zai)此上(shang)進(jin)(jin)行強夯施(shi)工(gong)后，土(tu)質就會造成坍塌，這(zhe)種(zhong)塌陷解(jie)決辦(ban)法也非常的簡(jian)單，前期做好測量，經過施(shi)工(gong)后回填土(tu)進(jin)(jin)行解(jie)決就可以(yi)了。

2 、水流沖刷塌陷

這個處理辦(ban)法很(hen)簡單，但是速度要快。盡快找到(dao)水(shui)流(liu)的(de)就可以的(de)，截(jie)住(zhu)后積水(shui)用(yong)水(shui)泵抽(chou)掉就行。

3 、地質復雜

這種情況其實也是(shi)比較的(de)多見，例如一(yi)些碎(sui)石地(di)帶，中間摻(chan)雜(za)著(zhu)一(yi)些大塊的(de)石頭，需要(yao)去除石頭之后再進行(xing)強夯。這樣也會造成(cheng)一(yi)定(ding)的(de)塌陷。處理(li)方式(shi)就是(shi)回(hui)填土的(de)時候盡量使用一(yi)些和(he)本地(di)土質接近的(de)方式(shi)進行(xing)回(hui)填。
