強夯試夯施工(gong)完后(hou)多久可以進行檢測

在建筑工(gong)(gong)程中，每一(yi)(yi)項(xiang)(xiang)施(shi)(shi)工(gong)(gong)完成(cheng)后都要(yao)經(jing)過檢(jian)驗，檢(jian)測合格(ge)后才(cai)能(neng)夠進(jin)(jin)行(xing)下(xia)一(yi)(yi)個項(xiang)(xiang)目的施(shi)(shi)工(gong)(gong)。強(qiang)(qiang)夯(hang)(hang)施(shi)(shi)工(gong)(gong)對的試夯(hang)(hang)也不例外，進(jin)(jin)行(xing)強(qiang)(qiang)夯(hang)(hang)效果檢(jian)測這是(shi)對工(gong)(gong)程質量合格(ge)與否的評定，一(yi)(yi)般強(qiang)(qiang)夯(hang)(hang)試夯(hang)(hang)施(shi)(shi)工(gong)(gong)后一(yi)(yi)周左右就可(ke)以進(jin)(jin)行(xing)檢(jian)測。

強(qiang)夯試夯后的檢(jian)測辦法：

1、淺層平(ping)板(ban)靜載(zai)試(shi)驗(yan)(yan)。該辦法(fa)是(shi)比較常見的(de)(de)(de)強(qiang)夯檢(jian)測(ce)辦法(fa)，首要(yao)可(ke)以檢(jian)測(ce)出強(qiang)夯后地基承載(zai)力能否到達(da)(da)規(gui)劃的(de)(de)(de)要(yao)求。一(yi)般的(de)(de)(de)做法(fa)為(wei)挖一(yi)個0.3-0.5m的(de)(de)(de)坑，找平(ping)后鋪上細沙，放(fang)(fang)置一(yi)塊面積約1㎡的(de)(de)(de)正方(fang)(fang)形(xing)或長方(fang)(fang)形(xing)鋼板(ban)，將(jiang)油壓(ya)(ya)千斤(jin)頂放(fang)(fang)置于承壓(ya)(ya)板(ban)中部(bu)。試(shi)驗(yan)(yan)時(shi)在承壓(ya)(ya)板(ban)上的(de)(de)(de)兩(liang)個對(dui)稱方(fang)(fang)位安(an)(an)放(fang)(fang)行(xing)程為(wei)0-50mm的(de)(de)(de)百(bai)(bai)分表，固定和支(zhi)承百(bai)(bai)分表的(de)(de)(de)磁性(xing)表座吸附于長4m的(de)(de)(de)基準梁(liang)上，基準梁(liang)的(de)(de)(de)兩(liang)頭要(yao)裝置安(an)(an)穩，保(bao)證不(bu)受外界影響而(er)發作位移，山西擠(ji)密樁基施工聯系(xi)方(fang)(fang)式，然(ran)后經過調理磁性(xing)表座使百(bai)(bai)分表指針調至50mm方(fang)(fang)位，若試(shi)件由于受壓(ya)(ya)而(er)沉降(jiang)(jiang)百(bai)(bai)分表指針將(jiang)移動指示沉降(jiang)(jiang)值。一(yi)般試(shi)驗(yan)(yan)時(shi)不(bu)僅只檢(jian)測(ce)是(shi)否可(ke)以到達(da)(da)合格規(gui)范，還會進行(xing)極(ji)限(xian)值測(ce)驗(yan)(yan)。

2、室(shi)內土(tu)工試(shi)(shi)驗(yan)(yan)。室(shi)內土(tu)工試(shi)(shi)驗(yan)(yan)是指經過對夯后取樣，到試(shi)(shi)驗(yan)(yan)室(shi)進行相關(guan)的測驗(yan)(yan)，并取得巖(yan)土(tu)的物理(li)性(xing)目(mu)標(biao)(biao)、力學性(xing)目(mu)標(biao)(biao)、滲透性(xing)目(mu)標(biao)(biao)以(yi)及動力性(xing)目(mu)標(biao)(biao)等的試(shi)(shi)驗(yan)(yan)作業(ye)。常見的目(mu)標(biao)(biao)有密實度、含水(shui)量、孔隙比、比重、塑液限等

3、動(dong)(dong)力(li)觸(chu)探(tan)。該辦(ban)法(fa)(fa)分為(wei)(wei)輕型(xing)動(dong)(dong)力(li)觸(chu)探(tan)和重(zhong)型(xing)動(dong)(dong)力(li)觸(chu)探(tan)。現在比較常(chang)見的(de)為(wei)(wei)重(zhong)型(xing)動(dong)(dong)力(li)觸(chu)探(tan)，該辦(ban)法(fa)(fa)是使用必(bi)定(ding)的(de)落錘質量，將(jiang)必(bi)定(ding)尺度(du)(du)、必(bi)定(ding)形狀的(de)探(tan)頭打入土(tu)中，依據打入的(de)難度(du)(du)，即貫入錘擊數(shu)，斷定(ding)土(tu)層稱號(hao)及(ji)其工程性質。該試驗辦(ban)法(fa)(fa)可有(you)用的(de)檢測出強夯施工后的(de)影(ying)響深度(du)(du)。

不均勻沉降(jiang)(jiang)(jiang)(jiang)的(de)(de)預防：基坑(keng)周圍(wei)建(jian)(jian)筑物(wu)的(de)(de)不均勻沉降(jiang)(jiang)(jiang)(jiang)主要是(shi)由(you)于地(di)下(xia)水(shui)(shui)位降(jiang)(jiang)(jiang)(jiang)低，建(jian)(jian)筑物(wu)下(xia)面地(di)基基礎脫水(shui)(shui)后承載能(neng)力降(jiang)(jiang)(jiang)(jiang)低，在重力作(zuo)用(yong)下(xia)被壓(ya)縮(suo)、固結(jie)。為防止此類不均勻沉降(jiang)(jiang)(jiang)(jiang)必(bi)須(xu)控制地(di)下(xia)水(shui)(shui)位過度、快速降(jiang)(jiang)(jiang)(jiang)低。通常采取減慢降(jiang)(jiang)(jiang)(jiang)水(shui)(shui)速度、打(da)(da)截滲帷幕、打(da)(da)井回灌地(di)下(xia)水(shui)(shui)等措施。其中(zhong)回灌地(di)下(xia)水(shui)(shui)的(de)(de)方(fang)案(an)比較簡單(dan)有效，只需在建(jian)(jian)筑物(wu)與降(jiang)(jiang)(jiang)(jiang)水(shui)(shui)井之間靠近建(jian)(jian)筑物(wu)的(de)(de)地(di)方(fang)打(da)(da)井并回灌地(di)下(xia)水(shui)(shui)，便可(ke)很大程度地(di)防止建(jian)(jian)筑物(wu)沉降(jiang)(jiang)(jiang)(jiang)。

井(jing)點施(shi)工(gong)的(de)質量(liang)：在井(jing)點施(shi)工(gong)的(de)過程(cheng)中要嚴格(ge)控制其質量(liang)，特(te)別是在放置(zhi)濾(lv)管(guan)和填(tian)充(chong)砂石(shi)的(de)過程(cheng)中，要防(fang)止井(jing)壁塌土堵塞(sai)濾(lv)管(guan)形成“死井(jing)”。同時，正確填(tian)充(chong)的(de)砂石(shi)可對地(di)(di)下水進行過濾(lv)，防(fang)止排(pai)水的(de)過程(cheng)中地(di)(di)下泥砂被大(da)(da)量(liang)抽出，既損害(hai)水泵又容易堵塞(sai)管(guan)道(dao)。而且，地(di)(di)下泥砂大(da)(da)量(liang)流(liu)失可能導致地(di)(di)面(mian)產生過多的(de)沉降(jiang)甚至于開裂(lie)、坍塌。

旋(xuan)挖灌注樁(zhuang)澆(jiao)注水(shui)下(xia)混凝土(tu)要求(qiu)

⑴對混凝土的技術要求

樁(zhuang)設計(ji)要求混凝(ning)土(tu)(tu)強度為C30，配(pei)比由商品(pin)混凝(ning)土(tu)(tu)供(gong)應商提供(gong)，粗骨料(liao)（碎石）粒徑不得大于25mm，坍落度180～220mm，采(cai)用普通硅(gui)酸鹽水泥，可適當摻加減水劑，摻量根據試驗確定。配(pei)制(zhi)的混凝(ning)土(tu)(tu)應具有良(liang)好的工作性能。

⑵混凝(ning)土(tu)澆(jiao)注前由技術人員檢查混凝(ning)土(tu)塌(ta)落度并記(ji)錄。混凝(ning)土(tu)在運輸、澆(jiao)筑過程(cheng)中不能產生離析(xi)現象。

⑶導(dao)管內使(shi)用的隔水(shui)塞球膽大小要合適，安裝要正(zheng)，一般位于水(shui)面(mian)以上。灌(guan)注混(hun)凝(ning)土前孔口要蓋嚴，防止混(hun)凝(ning)土落入孔中污染(ran)泥(ni)漿。

⑷混(hun)(hun)凝(ning)(ning)土(tu)(tu)首(shou)灌量應灌至導(dao)管(guan)(guan)下(xia)口2m以上，保(bao)證(zheng)首(shou)灌導(dao)管(guan)(guan)埋入(ru)混(hun)(hun)凝(ning)(ning)土(tu)(tu)為3m左右。混(hun)(hun)凝(ning)(ning)土(tu)(tu)澆注時，導(dao)管(guan)(guan)下(xia)口埋入(ru)混(hun)(hun)凝(ning)(ning)土(tu)(tu)的深度不小于(yu)2m，不大(da)于(yu)6m，設(she)專人及(ji)時測定(ding)，以便掌握導(dao)管(guan)(guan)提(ti)升高度。每次拆卸導(dao)管(guan)(guan)，必(bi)須(xu)經過測量計算(suan)導(dao)管(guan)(guan)埋深，然后確定(ding)卸管(guan)(guan)長度，使混(hun)(hun)凝(ning)(ning)土(tu)(tu)處(chu)于(yu)流動狀態，并作好澆注施工記(ji)錄。混(hun)(hun)凝(ning)(ning)土(tu)(tu)灌注必(bi)須(xu)連續(xu)進行，中(zhong)間(jian)不得(de)間(jian)斷。拆除后的導(dao)管(guan)(guan)放入(ru)架子中(zhong)并及(ji)時清洗(xi)干(gan)凈(jing)。
