強夯試夯施工(gong)完后多久可以進行檢測(ce)

在建筑工(gong)(gong)程中，每一(yi)(yi)項施(shi)(shi)工(gong)(gong)完成后(hou)都要(yao)經過檢驗(yan)，檢測合格(ge)后(hou)才能夠進行(xing)下一(yi)(yi)個項目(mu)的施(shi)(shi)工(gong)(gong)。強(qiang)(qiang)夯(hang)施(shi)(shi)工(gong)(gong)對(dui)的試夯(hang)也不(bu)例外，進行(xing)強(qiang)(qiang)夯(hang)效(xiao)果檢測這(zhe)是(shi)對(dui)工(gong)(gong)程質量合格(ge)與否(fou)的評定，一(yi)(yi)般強(qiang)(qiang)夯(hang)試夯(hang)施(shi)(shi)工(gong)(gong)后(hou)一(yi)(yi)周左(zuo)右就可(ke)以進行(xing)檢測。

強(qiang)夯試夯后的(de)檢測辦法：

1、淺層平板(ban)(ban)靜載試驗(yan)(yan)。該辦(ban)法(fa)(fa)是(shi)(shi)比(bi)較常見的(de)強夯檢測(ce)辦(ban)法(fa)(fa)，首(shou)要可以檢測(ce)出強夯后(hou)地基承(cheng)載力能(neng)否到達規(gui)劃的(de)要求。一(yi)(yi)(yi)般(ban)(ban)的(de)做法(fa)(fa)為挖一(yi)(yi)(yi)個0.3-0.5m的(de)坑(keng)，找平后(hou)鋪(pu)上(shang)細沙(sha)，放(fang)置一(yi)(yi)(yi)塊面積(ji)約1㎡的(de)正方形(xing)或長方形(xing)鋼板(ban)(ban)，將油(you)壓(ya)千斤頂放(fang)置于承(cheng)壓(ya)板(ban)(ban)中部。試驗(yan)(yan)時(shi)在承(cheng)壓(ya)板(ban)(ban)上(shang)的(de)兩個對稱方位安放(fang)行程為0-50mm的(de)百分表(biao)(biao)，固(gu)定和支承(cheng)百分表(biao)(biao)的(de)磁(ci)性表(biao)(biao)座(zuo)吸附(fu)于長4m的(de)基準梁(liang)上(shang)，基準梁(liang)的(de)兩頭要裝置安穩(wen)，保證(zheng)不(bu)受(shou)外界影(ying)響而發(fa)作位移，然后(hou)經(jing)過調理磁(ci)性表(biao)(biao)座(zuo)使百分表(biao)(biao)指(zhi)針調至50mm方位，若試件由(you)于受(shou)壓(ya)而沉(chen)降百分表(biao)(biao)指(zhi)針將移動指(zhi)示(shi)沉(chen)降值(zhi)(zhi)。一(yi)(yi)(yi)般(ban)(ban)試驗(yan)(yan)時(shi)不(bu)僅只檢測(ce)是(shi)(shi)否可以到達合(he)格規(gui)范，還會進行極(ji)限值(zhi)(zhi)測(ce)驗(yan)(yan)。

2、室(shi)內(nei)土工試驗。室(shi)內(nei)土工試驗是指經過對(dui)夯后(hou)取(qu)樣，山西擠密樁基施工費用多少，到試驗室(shi)進行相關的測驗，并取(qu)得(de)巖土的物理性(xing)(xing)(xing)目(mu)(mu)標(biao)(biao)(biao)、力學性(xing)(xing)(xing)目(mu)(mu)標(biao)(biao)(biao)、滲透性(xing)(xing)(xing)目(mu)(mu)標(biao)(biao)(biao)以及動力性(xing)(xing)(xing)目(mu)(mu)標(biao)(biao)(biao)等的試驗作業(ye)。常見的目(mu)(mu)標(biao)(biao)(biao)有密實度、含(han)水量、孔隙比、比重、塑液限等

3、動力觸探。該辦法(fa)分為輕型(xing)動力觸探和重型(xing)動力觸探。現在(zai)比較常見的(de)(de)為重型(xing)動力觸探，該辦法(fa)是(shi)使用(yong)必定的(de)(de)落錘質(zhi)量，將必定尺度(du)、必定形狀(zhuang)的(de)(de)探頭打(da)入土(tu)中，依據打(da)入的(de)(de)難度(du)，即貫入錘擊數，斷定土(tu)層稱號及其工(gong)程性質(zhi)。該試驗辦法(fa)可有用(yong)的(de)(de)檢測出強夯施工(gong)后的(de)(de)影響深(shen)度(du)。
