碎石樁的施(shi)工質量控(kong)制：

質量控制要求：

1、施工(gong)(gong)前根(gen)據(ju)工(gong)(gong)藝要求(qiu)設計進行工(gong)(gong)藝性試(shi)樁(zhuang)，不少于(yu)2根(gen)，以掌握對現場的制樁(zhuang)經驗及(ji)各種(zhong)操作(zuo)技術參數。

2、根據地面高(gao)程(cheng)和設計(ji)樁底高(gao)程(cheng)的關系(xi)，在套管上(shang)畫上(shang)設計(ji)深度線，以保證直觀的觀察到套管的入土(tu)深度。

3、正式施(shi)工時，嚴格按照設(she)計樁(zhuang)長(chang)、樁(zhuang)徑、樁(zhuang)間(jian)(jian)距、碎(sui)石灌入(ru)量及試驗確定(ding)的樁(zhuang)管提升高度、擠密次(ci)數(shu)和留振時間(jian)(jian)、電機工作電流等施(shi)工參數(shu)進行(xing)施(shi)工，以確保擠密均勻(yun)和樁(zhuang)身的連續性。

4、法擠密(mi)應根據錘擊的能量，控制分(fen)段的填石(shi)量和成樁(zhuang)的長度。并按貫入度控制，保證樁(zhuang)身的連續性、密(mi)實性及(ji)其周圍土層(ceng)擠密(mi)后的均勻性。

5、實(shi)際灌入(ru)(ru)量(liang)沒(mei)有(you)達到設計用量(liang)要求(qiu)時(shi)，應在原位將樁管打入(ru)(ru)，補(bu)充(chong)灌碎石(shi)后復打一(yi)次，或在旁邊補(bu)樁一(yi)根。樁體在施工(gong)中必須確保連接、密實(shi)。

6、加(jia)料(liao)按分(fen)批加(jia)料(liao)，控制數量，按少吃(chi)多餐原(yuan)則進(jin)行，每段樁體(ti)在沒有達到(dao)規定(ding)的密實度(du)時須(xu)繼(ji)續(xu)加(jia)料(liao)振實。

7、拔(ba)管速度不得過快(kuai)，出碎石要充(chong)分，排(pai)石不暢時可適當提升(sheng)提升(sheng)高度。

8、碎石(shi)樁(zhuang)的施工順序應外圍向中(zhong)間進(jin)行(xing)，或由一(yi)邊推(tui)向另一(yi)邊的方(fang)式施工。

9、樁(zhuang)體(ti)施工完畢(bi)后應將頂部松(song)散樁(zhuang)體(ti)挖(wa)除或壓(ya)實。

10、碎石樁(zhuang)施工完(wan)成檢查(cha)合格且符合設計要求后，方可(ke)進行下到工序(砂礫(li)石墊層)施工。

強夯試夯施工完(wan)后多(duo)久可以進(jin)行檢測

在建筑工(gong)程中，每一項施(shi)工(gong)完成后(hou)(hou)都要(yao)經過(guo)檢(jian)驗，檢(jian)測(ce)合(he)格后(hou)(hou)才能(neng)夠進行下一個(ge)項目的施(shi)工(gong)。強夯(hang)施(shi)工(gong)對的試夯(hang)也不例外(wai)，進行強夯(hang)效(xiao)果檢(jian)測(ce)這(zhe)是對工(gong)程質量(liang)合(he)格與否的評定(ding)，一般(ban)強夯(hang)試夯(hang)施(shi)工(gong)后(hou)(hou)一周左右就(jiu)可以進行檢(jian)測(ce)。

強夯試夯后的檢測辦法：

1、淺層平板(ban)靜載(zai)試(shi)驗(yan)。該辦法(fa)是(shi)比較常見的強(qiang)夯檢測辦法(fa)，首要可以(yi)檢測出強(qiang)夯后(hou)地(di)基(ji)(ji)承載(zai)力能(neng)否到(dao)達規劃的要求。一般的做法(fa)為挖一個0.3-0.5m的坑(keng)，找平后(hou)鋪(pu)上細沙，放置(zhi)一塊面積約(yue)1㎡的正方(fang)(fang)形或長方(fang)(fang)形鋼板(ban)，將油壓千斤頂放置(zhi)于承壓板(ban)中部。試(shi)驗(yan)時在承壓板(ban)上的兩個對稱方(fang)(fang)位安(an)放行程為0-50mm的百(bai)分(fen)表(biao)，固定和支承百(bai)分(fen)表(biao)的磁性(xing)表(biao)座吸附于長4m的基(ji)(ji)準梁上，基(ji)(ji)準梁的兩頭要裝置(zhi)安(an)穩，保證不受外(wai)界(jie)影響而發作(zuo)位移，然后(hou)經過調(diao)理磁性(xing)表(biao)座使百(bai)分(fen)表(biao)指針調(diao)至50mm方(fang)(fang)位，若試(shi)件由于受壓而沉(chen)降(jiang)百(bai)分(fen)表(biao)指針將移動指示沉(chen)降(jiang)值(zhi)。一般試(shi)驗(yan)時不僅只檢測是(shi)否可以(yi)到(dao)達合格規范，還會進行極限值(zhi)測驗(yan)。

2、室內土工(gong)試(shi)(shi)驗(yan)。室內土工(gong)試(shi)(shi)驗(yan)是指經(jing)過對夯后取樣，到試(shi)(shi)驗(yan)室進行相關(guan)的測驗(yan)，并取得(de)巖土的物理性目標(biao)、力學性目標(biao)、滲(shen)透(tou)性目標(biao)以及動(dong)力性目標(biao)等的試(shi)(shi)驗(yan)作業(ye)。常(chang)見(jian)的目標(biao)有密實度(du)、含水量、孔隙比(bi)、比(bi)重、塑液限等

3、動(dong)力觸(chu)探。該辦法(fa)分為輕型(xing)動(dong)力觸(chu)探和重型(xing)動(dong)力觸(chu)探。現在比較(jiao)常(chang)見的(de)(de)(de)為重型(xing)動(dong)力觸(chu)探，該辦法(fa)是(shi)使(shi)用必(bi)(bi)定(ding)的(de)(de)(de)落錘(chui)質量，將(jiang)必(bi)(bi)定(ding)尺(chi)度、必(bi)(bi)定(ding)形狀的(de)(de)(de)探頭打(da)入(ru)土(tu)中(zhong)，山西素土(tu)擠密樁施工(gong)(gong)(gong)費(fei)用，依據(ju)打(da)入(ru)的(de)(de)(de)難度，即貫(guan)入(ru)錘(chui)擊數，斷(duan)定(ding)土(tu)層稱(cheng)號及(ji)其工(gong)(gong)(gong)程性質。該試驗(yan)辦法(fa)可(ke)有用的(de)(de)(de)檢(jian)測出強夯施工(gong)(gong)(gong)后的(de)(de)(de)影響(xiang)深度。
