滿(man)夯(hang)跟(gen)強夯(hang)施(shi)工有什么(me)不一(yi)樣的(de)地方呢？

滿(man)夯是強夯施工(gong)地基處理(li)中的在其中一(yi)種加工(gong)工(gong)藝，一(yi)般來(lai)說滿(man)夯的使用大概(gai)可依照(zhao)下邊的步驟開展。

1、主復夯所有工(gong)程(cheng)施工(gong)完畢以后(hou)，大(da)家會(hui)(hui)對不(bu)一樣(yang)土層開展區別，區分后(hou)的土層靜養時間也會(hui)(hui)不(bu)一樣(yang)，須直到孔隙度(du)中(zhong)的水清(qing)除后(hou)，才可以推(tui)行滿夯施工(gong)技術。

2、滿(man)夯(hang)關鍵功能(neng)于表層，這(zhe)兒的表層的含意關鍵指：主夯(hang)擊點高(gao)電子能(neng)級夯(hang)擊震動(dong)造成松脫的地表層土。此外在開展滿(man)夯(hang)加(jia)工工藝進行(xing)流程(cheng)中，其(qi)夯(hang)擊能(neng)通常是主夯(hang)點夯(hang)擊能(neng)的二分之一。除此之外通過滿(man)夯(hang)后的地表要加(jia)一遍輾壓。

3、滿夯的(de)(de)(de)工(gong)程施工(gong)通常采用四分之一的(de)(de)(de)錘徑，開展雙重鋼筋搭接(jie)。夯錘夯擊的(de)(de)(de)次數、每(mei)一次點一下的(de)(de)(de)數目(mu)及其鋼筋搭接(jie)都應當依(yi)照試夯明確的(de)(de)(de)技(ji)術(shu)參數來工(gong)程施工(gong)，需注(zhu)意的(de)(de)(de)是不可(ke)以發生漏(lou)夯的(de)(de)(de)狀(zhuang)況(kuang)。

滿(man)夯(hang)(hang)(hang)(hang)是對回填(tian)土后的(de)(de)地土壤層采用聯合分布的(de)(de)夯(hang)(hang)(hang)(hang)實(shi)(shi)，并且(qie)是不可忽略的(de)(de)。因此它主(zhu)要是對夯(hang)(hang)(hang)(hang)實(shi)(shi)品質的(de)(de)嚴格管理(li)。殊不知與眾(zhong)不同(tong)的(de)(de)是強夯(hang)(hang)(hang)(hang)地基主(zhu)要是應用大落距、大凈重的(de)(de)夯(hang)(hang)(hang)(hang)錘，來夯(hang)(hang)(hang)(hang)實(shi)(shi)回填(tian)，這也是一(yi)般夯(hang)(hang)(hang)(hang)實(shi)(shi)加工(gong)工(gong)藝沒法或難(nan)以做(zuo)到的(de)(de)實(shi)(shi)際效果。

滿夯的動能較低(di)，應(ying)用(yong)低(di)動能夯錘(chui)夯擊，用(yong)以表層。此(ci)外落夯點中(zhong)間互相密切排序，不容(rong)易存有(you)空隙。每擊夯點的間距(ju)(ju)距(ju)(ju)離(li)為(wei)零。它規定互壓或鋼筋搭接錘(chui)印，少夯很多遍。
