不(bu)均勻(yun)沉(chen)降(jiang)(jiang)的(de)預防(fang)：基坑(keng)周圍建(jian)筑(zhu)物(wu)的(de)不(bu)均勻(yun)沉(chen)降(jiang)(jiang)主要是由于地下(xia)水(shui)位(wei)降(jiang)(jiang)低(di)，建(jian)筑(zhu)物(wu)下(xia)面地基基礎脫(tuo)水(shui)后承載能(neng)力(li)降(jiang)(jiang)低(di)，在重力(li)作用下(xia)被壓縮(suo)、固結。為防(fang)止此類不(bu)均勻(yun)沉(chen)降(jiang)(jiang)必須(xu)控(kong)制(zhi)地下(xia)水(shui)位(wei)過度(du)、快速降(jiang)(jiang)低(di)。通常采(cai)取減慢降(jiang)(jiang)水(shui)速度(du)、打(da)截滲(shen)帷幕、打(da)井(jing)回灌地下(xia)水(shui)等措施。其中回灌地下(xia)水(shui)的(de)方(fang)案比較(jiao)簡單有效(xiao)，只需在建(jian)筑(zhu)物(wu)與(yu)降(jiang)(jiang)水(shui)井(jing)之間靠近建(jian)筑(zhu)物(wu)的(de)地方(fang)打(da)井(jing)并(bing)回灌地下(xia)水(shui)，便可很(hen)大(da)程度(du)地防(fang)止建(jian)筑(zhu)物(wu)沉(chen)降(jiang)(jiang)。

強夯(hang)機安全操(cao)作注意事項(xiang)有哪些？

強夯機是建筑工(gong)程(cheng)施工(gong)的(de)設(she)備(bei)，主要用來(lai)對(dui)松土(tu)壓(ya)實處理。強夯機操作的(de)時候有些(xie)需要注意(yi)的(de)事項，接下來(lai)我(wo)們來(lai)詳細的(de)介紹一下。

1、擔任強(qiang)夯工作的主機(ji)(ji)，應(ying)按照強(qiang)夯等(deng)級的請(qing)求通過(guo)核算選用。用履(lv)帶式起(qi)重機(ji)(ji)作主機(ji)(ji)的，應(ying)履(lv)行履(lv)帶式起(qi)重機(ji)(ji)的有(you)關規定(ding)。

2、強(qiang)夯機的工作場(chang)所應平(ping)坦，門架底座與夯機著地部(bu)位應堅持水平(ping)，山(shan)西擠密樁基施工，當(dang)下(xia)沉超越100mm時，應從頭墊(dian)高。

3、強夯機(ji)械的(de)門(men)架(jia)、橫梁(liang)、脫鉤器等首要構造和部(bu)件的(de)材料(liao)及制造質量，應(ying)通(tong)過嚴厲查(cha)看(kan)，對不(bu)契合(he)規劃請求的(de)，不(bu)得運用。

4、工作前強夯(hang)機要點查(cha)看項目應契合下列請求：

1)各部件銜接好，無松動。

2)內(nei)燃沖擊夯有(you)滿足(zu)的(de)潤滑油，油門控制器(qi)滾動(dong)靈敏。

3)電動(dong)沖擊夯有(you)牢靠的接零或接地，山西擠密(mi)樁基施工費用(yong)多(duo)少，電纜線(xian)絕(jue)緣無缺。

5、內燃(ran)沖擊(ji)夯(hang)發動后(hou)(hou)，內燃(ran)機應怠速工作(zuo)3—5min，然(ran)后(hou)(hou)逐步(bu)加大油(you)門，待夯(hang)機跳動安穩后(hou)(hou)，方可工作(zuo)。

6、電動(dong)沖擊(ji)夯在接(jie)通電源發動(dong)后，應查(cha)看電動(dong)機旋轉方向，有錯誤(wu)時應倒換相線。

7、夯機在工作(zuo)狀況時，起重臂仰角應置(zhi)于(yu)70°。

8、梯形門(men)架支腿不得前后錯位，門(men)架支腿在未支穩(wen)墊實前，不得提錘。

9、改換夯位后，應(ying)從(cong)頭(tou)查看門架支腿(tui)，承認安(an)定牢(lao)靠，然后再將錘(chui)提高100～300mm，查看整機的安(an)穩性，承認牢(lao)靠后，方可(ke)工作(zuo)。

10、夯(hang)錘(chui)下落后(hou)，在吊鉤沒(mei)有降至夯(hang)錘(chui)吊環附近前，操作人員不(bu)得提早下坑掛鉤。從坑中提錘(chui)時，禁(jin)止掛鉤人員站在錘(chui)上隨錘(chui)提高。
