強(qiang)(qiang)夯工程(cheng)---強(qiang)(qiang)夯地基施工法(fa)是大多數(shu)建筑地基處(chu)理的常用(yong)施工方法(fa)。在強(qiang)(qiang)夯地基處(chu)理過程(cheng)中，使用(yong)強(qiang)(qiang)夯設備(bei)是不(bu)可避免的。我們(men)來談(tan)談(tan)常用(yong)的強(qiang)(qiang)夯設備(bei)：

1、夯錘

強夯(hang)錘的重量一般為(wei)10～40t，底部方(fang)法多為(wei)圓形(xing)或多邊形(xing)。

2、起重設備

強夯工程的起(qi)重設備的起(qi)重能(neng)力應大(da)于(yu)錘子(zi)重量的1.5倍(bei)，并應選擇履帶起(qi)重機或其(qi)他15t以上的起(qi)重設備。

3、推土機

履(lv)帶(dai)式推土機用于強夯工程夯實坑的回填(tian)和平整。

4、自動解耦設備

擠(ji)(ji)密樁(zhuang)(zhuang)(zhuang)(zhuang)基施(shi)工(gong)(gong)(gong)，灰土擠(ji)(ji)密樁(zhuang)(zhuang)(zhuang)(zhuang)施(shi)工(gong)(gong)(gong)，環保(bao)擠(ji)(ji)密樁(zhuang)(zhuang)(zhuang)(zhuang)施(shi)工(gong)(gong)(gong)，水(shui)泥(ni)土擠(ji)(ji)密樁(zhuang)(zhuang)(zhuang)(zhuang)施(shi)工(gong)(gong)(gong)，素土擠(ji)(ji)密樁(zhuang)(zhuang)(zhuang)(zhuang)施(shi)工(gong)(gong)(gong)，夯擴擠(ji)(ji)密樁(zhuang)(zhuang)(zhuang)(zhuang)施(shi)工(gong)(gong)(gong)，沉管擠(ji)(ji)密樁(zhuang)(zhuang)(zhuang)(zhuang)施(shi)工(gong)(gong)(gong)，強夯地基施(shi)工(gong)(gong)(gong)，碎石(shi)擠(ji)(ji)密樁(zhuang)(zhuang)(zhuang)(zhuang)施(shi)工(gong)(gong)(gong)，擠(ji)(ji)密螺紋樁(zhuang)(zhuang)(zhuang)(zhuang)施(shi)工(gong)(gong)(gong)，鉆孔灌注樁(zhuang)(zhuang)(zhuang)(zhuang)施(shi)工(gong)(gong)(gong)，軟土地基施(shi)工(gong)(gong)(gong)，灰土樁(zhuang)(zhuang)(zhuang)(zhuang)施(shi)工(gong)(gong)(gong)，我公司(si)主營：擠(ji)(ji)密樁(zhuang)(zhuang)(zhuang)(zhuang)施(shi)工(gong)(gong)(gong)，擠(ji)(ji)密樁(zhuang)(zhuang)(zhuang)(zhuang)工(gong)(gong)(gong)程

我(wo)們將為你提供(gong)詳(xiang)細的流行資訊，精(jing)彩的新(xin)聞(wen)知識，讓您對產品有更深的了解

1.強夯置換地基的(de)適用性和處理效果要通(tong)過現(xian)場試(shi)驗(yan)(yan)確定(ding)。在進(jin)行強夯置換施(shi)工前，擠(ji)密樁施(shi)工方案，應(ying)在施(shi)工現(xian)場有代表性的(de)場地選(xuan)擇一個(ge)或幾個(ge)試(shi)驗(yan)(yan)區(qu)進(jin)行試(shi)夯或試(shi)驗(yan)(yan)性施(shi)工。每個(ge)實驗(yan)(yan)區(qu)的(de)面積不應(ying)小于(yu)20m×20m。

2.強(qiang)夯地基(ji)用(yong)夯錘(chui)(chui)的(de)(de)質(zhi)量(liang)應為(wei)10-60t，其(qi)底部和形(xing)式應為(wei)網狀形(xing)，夯錘(chui)(chui)底部的(de)(de)面積應根(gen)據(ju)土(tu)壤的(de)(de)性質(zhi)確定，夯錘(chui)(chui)底部的(de)(de)靜態接(jie)地壓(ya)力應為(wei)25-80kPa。敲擊(ji)能量(liang)高(gao)時點擊(ji)高(gao)值(zhi)，夯擊(ji)能量(liang)低(di)時點擊(ji)低(di)值(zhi)，細粒土(tu)使(shi)用(yong)低(di)值(zhi)。錘(chui)(chui)頭底面應對稱設置若干(gan)個從上至下(xia)貫通的(de)(de)排氣孔(kong)，孔(kong)徑(jing)為(wei)300-400 mm。

3.基(ji)礎夯(hang)實應(ying)采(cai)(cai)用(yong)帶(dai)自動脫(tuo)鉤裝置(zhi)的履帶(dai)吊(diao)，夯(hang)錘質量不應(ying)超過起重機械的額定(ding)起重質量。履帶(dai)吊(diao)應(ying)在吊(diao)臂末端(duan)設置(zhi)輔助(zhu)龍門架(jia)或(huo)采(cai)(cai)取其(qi)他安全措施(shi)，防(fang)止(zhi)起落錘在起升(sheng)落錘時傾覆。

4.地(di)質中常見(jian)的(de)問題(ti)是(shi)軟土，處理軟土常用的(de)方(fang)法是(shi)強夯(hang)。強夯(hang)置換(huan)法對于適合強夯(hang)的(de)環境稍(shao)微寬松一點，適合高飽和度(du)的(de)淤泥，對地(di)基的(de)變形控(kong)制不會太嚴格。在設計(ji)之前，不能省略現場實驗(yan)，這是(shi)為了對其性(xing)能有一個(ge)大致的(de)把握。
