素土擠密樁施工工藝

1、定位放線：

① 坐標投測

依據建設單位(wei)提供(gong)的坐標點用全(quan)站(zhan)儀或(huo)GPS進(jin)行(xing)工程定位(wei)，在(zai)基坑上邊選擇可保留(liu)位(wei)置埋設、固定少4個控(kong)制點，東(dong)西、南北方向各兩(liang)個點，并在(zai)基坑底部(bu)施放出樓的四條周邊軸(zhou)線，打入木樁(zhuang)并釘小鐵釘，地面以上外漏30～50cm。

② 高程投測

依據(ju)建(jian)設單位(wei)提供的(de)(de)高程(cheng)(cheng)控(kong)制點(dian)用水(shui)準儀在基(ji)坑周邊制定(ding)出長期保留的(de)(de)樓(lou)的(de)(de)±0.000，依此在樓(lou)基(ji)坑四(si)周坑壁上釘(ding)鋼筋頭，做出基(ji)坑高程(cheng)(cheng)控(kong)制點(dian)。

③ 樁位放線

依據基坑底部四條邊軸線按照圖(tu)紙(zhi)設計(ji)樁間距(ju)、排距(ju)定出(chu)樁位(wei)，在樁心釘(ding)入鐵(tie)釬，并做白灰明示。

2、擠密樁成孔

成孔(kong)(kong)施(shi)工(gong)前，沉管擠密(mi)樁施(shi)工(gong)工(gong)程，應先制定出(chu)成孔(kong)(kong)路線(xian)圖，并對所有樁進行編號。

依據圖紙設計選用成(cheng)孔(kong)機械(xie)進行施(shi)工，并保(bao)證成(cheng)孔(kong)桿(gan)豎直(zhi)，對準(zhun)樁(zhuang)心，在成(cheng)孔(kong)桿(gan)頂端位置用紅油漆畫出設計樁(zhuang)深，以控(kong)制(zhi)成(cheng)孔(kong)深度滿足設計要求。

成孔(kong)過程(cheng)，采用(yong)由外向(xiang)內，隔排(pai)跳打進行。

強(qiang)夯(hang)工程施(shi)工法在地基加固中(zhong)的運用！

強(qiang)夯工(gong)程施工(gong)法解決路(lu)(lu)基是籍重錘式從(cong)高空(kong)隨意落下來給路(lu)(lu)基土(tu)(tu)施加撞擊力和(he)震(zhen)動，進(jin)(jin)(jin)而做到提升路(lu)(lu)基土(tu)(tu)的(de)抗(kang)壓強(qiang)度并減少其膨脹性，還能改進(jin)(jin)(jin)其抗(kang)震(zhen)動汽化的(de)功能和(he)清除(chu)土(tu)(tu)的(de)濕(shi)陷(xian)性。強(qiang)夯法在進(jin)(jin)(jin)行時僅用以結構加固(gu)沙子和(he)砂(sha)土(tu)(tu)路(lu)(lu)基。通過幾十年來的(de)運用與發(fa)展趨勢，它已適用從(cong)砂(sha)礫到粘性土(tu)(tu)的(de)各種路(lu)(lu)基土(tu)(tu)，這主要(yao)是由工(gong)程施工(gong)方式 的(de)完善和(he)排水管道標準的(de)改進(jin)(jin)(jin)。

強夯法(fa)又(you)稱(cheng)之為驅動力(li)預壓法(fa)或驅動力(li)夯實(shi)法(fa)。這類辦法(fa)是不斷將重錘式(一般(ban)為10～40t)提(ti)及高(gao)空使其隨(sui)意(yi)落下來(一般(ban)落距為10～40m)夯擊(ji)路基(ji)(ji)，進而(er)使路基(ji)(ji)的(de)(de)硬度(du)提(ti)升、膨脹(zhang)性獲得減少的(de)(de)方式。強夯法(fa)因為具備結構加固效(xiao)果非常(chang)的(de)(de)好、適用土(tu)的(de)(de)分類廣、機(ji)器設(she)備簡易、工(gong)(gong)(gong)(gong)程(cheng)施工(gong)(gong)(gong)(gong)便捷、節(jie)(jie)約人力(li)、工(gong)(gong)(gong)(gong)期短(duan)、節(jie)(jie)省原材料、工(gong)(gong)(gong)(gong)程(cheng)施工(gong)(gong)(gong)(gong)文明行為和工(gong)(gong)(gong)(gong)程(cheng)施工(gong)(gong)(gong)(gong)花費劣等優勢(shi)，迅速就推(tui)廣到(dao)各地區。

強(qiang)夯工(gong)程施工(gong)法適(shi)用(yong)(yong)解(jie)(jie)(jie)決(jue)砂土(tu)(tu)(tu)、碎石土(tu)(tu)(tu)、砂土(tu)(tu)(tu)、粘性(xing)(xing)(xing)土(tu)(tu)(tu)、濕陷性(xing)(xing)(xing)黃土(tu)(tu)(tu)和素填土(tu)(tu)(tu)等路(lu)(lu)基(ji)(ji)(ji)，它不(bu)(bu)但(dan)能提升(sheng)路(lu)(lu)基(ji)(ji)(ji)的抗壓強(qiang)度、減少其(qi)膨脹性(xing)(xing)(xing)、還(huan)能改進其(qi)抗震(zhen)動汽化的功能和清除(chu)土(tu)(tu)(tu)的濕陷性(xing)(xing)(xing)，因此還(huan)常見(jian)于解(jie)(jie)(jie)決(jue)可液化碎石土(tu)(tu)(tu)路(lu)(lu)基(ji)(ji)(ji)和濕陷性(xing)(xing)(xing)路(lu)(lu)基(ji)(ji)(ji)等。強(qiang)夯法針對(dui)對(dui)比度較高的粘性(xing)(xing)(xing)土(tu)(tu)(tu)，一般來說解(jie)(jie)(jie)決(jue)作用(yong)(yong)不(bu)(bu)顯著，尤其(qi)是污泥(ni)和淤泥(ni)質土(tu)(tu)(tu)地資源基(ji)(ji)(ji)，解(jie)(jie)(jie)決(jue)實際效果更差。因而針對(dui)污泥(ni)質土(tu)(tu)(tu)地資源基(ji)(ji)(ji)應(ying)慎(shen)重采用(yong)(yong)或采取(qu)別的方式。
