１ 干振碎石樁的定義和原理

干振(zhen)碎(sui)石(shi)樁是采用預沉導管、重錘(chui)振(zhen)動(dong)壓(ya)入工藝(yi)施工的碎(sui)石(shi)樁。其原理主要(yao)是振(zhen)密(mi)和擠密(mi)松散沙土、粉土、黏性土、素填土、雜填土等(deng)地(di)基。

２ 原材料要求

碎石(shi)樁施(shi)(shi)工(gong)碎石(shi)由(you)巖(yan)石(shi)或礫(li)石(shi)軋制而成，應潔凈、干燥并具有(you)足夠的(de)強(qiang)度和耐磨耗性，其(qi)顆(ke)粒形狀應具有(you)棱角(jiao)，不(bu)(bu)得摻有(you)軟質和其(qi)他雜質。施(shi)(shi)工(gong)中采用天然級配為ｌ ｃｍ～３ ｃｍ的(de)碎石(shi)，含泥(ni)量小于５％，并不(bu)(bu)得含有(you)大(da)于４ ｃｍ的(de)顆(ke)粒。

３ 機械設備的要求

干振碎(sui)石樁需采用走管(guan)式或履帶式振動成樁機(ji)，內置平底活頁式樁尖，樁管(guan)ｄ ４２６ ｍｍ，樁管(guan)長度為設計樁長加３ ｍ，并設有(you)二(er)次投料口，錘(chui)重大(da)于(yu) ３５ ｋＮ，工(gong)作電流８０ Ａ左右，激振力大(da)于(yu)２８０ ｋＮ，配備發電機(ji)功率大(da)于(yu)１２０ ｋＷ。

灰土(tu)地基工程(cheng)施工注(zhu)意要點

1）未按要(yao)求(qiu)測定(ding)干土(tu)(tu)(tu)的質量(liang)(liang)密度：灰土(tu)(tu)(tu)回填施(shi)工(gong)時，切記每層灰土(tu)(tu)(tu)夯實都得測定(ding)干土(tu)(tu)(tu)的質量(liang)(liang)密度，符合(he)要(yao)求(qiu)后(hou)，才能鋪攤(tan)上層的灰土(tu)(tu)(tu)。并且在實驗(yan)報告中，注明土(tu)(tu)(tu)料種類、配(pei)合(he)比、試(shi)驗(yan)日(ri)期、層數（步數）、結(jie)論、試(shi)驗(yan)人員簽字等。密實度未達設計要(yao)求(qiu)的部位，樓(lou)房灰土(tu)(tu)(tu)樁施(shi)工(gong)加固，均應有處理方法和復驗(yan)結(jie)果。

2）留(liu)、接(jie)槎(cha)不符合規定(ding)：灰(hui)土(tu)施工(gong)時(shi)嚴格執(zhi)行留(liu)接(jie)的(de)(de)規定(ding)。當灰(hui)土(tu)基礎(chu)標(biao)高不同時(shi)，應作(zuo)成階梯形，上下層的(de)(de)灰(hui)土(tu)接(jie)槎(cha)距離(li)不得(de)小(xiao)于500㎜.接(jie)槎(cha)的(de)(de)規定(ding)。當灰(hui)土(tu)基礎(chu)標(biao)高不同時(shi)，應作(zuo)成階梯形，上下層的(de)(de)灰(hui)土(tu)接(jie)槎(cha)距離(li)不得(de)小(xiao)于500㎜.接(jie)槎(cha)的(de)(de)槎(cha)子應垂直切(qie)齊。

3）生石灰(hui)塊熟化不良：沒有認真過篩，顆粒過大，造(zao)成顆粒遇水(shui)熟化體積膨脹，會將上層墊層、基礎拱裂。務必(bi)認真對待熟石灰(hui)的過篩要求。

說(shuo)到強(qiang)夯(hang)(hang)施工(gong)(gong)隊，可能很多人都不太了解。其實這是我們在強(qiang)夯(hang)(hang)施工(gong)(gong)隊建(jian)設夯(hang)(hang)實基礎(chu)的過(guo)程(cheng)中經常(chang)看(kan)到的一個術(shu)語。強(qiang)夯(hang)(hang)施工(gong)(gong)隊處理(li)的目(mu)的是保(bao)證施工(gong)(gong)過(guo)程(cheng)中的安(an)全，解決施工(gong)(gong)前的一系列麻煩(fan)。比如幫助改(gai)善施工(gong)(gong)中的收縮特(te)性(xing)，這是由(you)于地基本身的高度(du)收縮，說(shuo)明(ming)對建(jian)筑物的沉降(jiang)和差(cha)異(yi)沉降(jiang)比較大，需要(yao)采取一定的措施使(shi)地基土收縮，進而提高收縮模量。

強(qiang)夯施(shi)(shi)工隊(dui)處(chu)理(li)有助于改(gai)善剪(jian)切特性，從(cong)而(er)(er)避(bi)免(mian)剪(jian)切破(po)壞，增強(qiang)地(di)基(ji)土的(de)(de)抗(kang)剪(jian)強(qiang)度，進而(er)(er)避(bi)免(mian)因地(di)基(ji)承載(zai)力差(cha)而(er)(er)造成的(de)(de)坑底起(qi)拱；改(gai)善透水(shui)特性，很(hen)多人都知道大壩或房屋可能會(hui)發生滲水(shui)，強(qiang)夯施(shi)(shi)工隊(dui)處(chu)理(li)就是通過研究地(di)基(ji)本身的(de)(de)透水(shui)性和不透水(shui)性來(lai)實(shi)施(shi)(shi)一定的(de)(de)措施(shi)(shi)，忻州灰(hui)土樁(zhuang)施(shi)(shi)工，進而(er)(er)避(bi)免(mian)開挖時的(de)(de)滲水(shui)。

在施工(gong)過程中，不可避免地會遇到(dao)一些(xie)特殊的土(tu)(tu)(tu)。強夯(hang)施工(gong)隊處理對特殊土(tu)(tu)(tu)也有很大(da)的改良作(zuo)用，有助于消除或降低黃土(tu)(tu)(tu)中的濕陷性(xing)，也有助于處理膨脹(zhang)土(tu)(tu)(tu)的膨脹(zhang)性(xing)。
