強夯工(gong)程時遇到塌陷(xian)問(wen)題應該如何處(chu)理？

強夯(hang)施(shi)(shi)工(gong)的(de)過程(cheng)中會遇(yu)許(xu)多的(de)問(wen)題，強夯(hang)施(shi)(shi)工(gong)團隊都會根據(ju)具體(ti)情況找到(dao)到(dao)相對應的(de)預防措(cuo)施(shi)(shi)和解決方案(an)，今(jin)天跟大(da)家分(fen)享的(de)一下如(ru)果在強夯(hang)過程(cheng)中遇(yu)到(dao)塌陷問(wen)題應當(dang)如(ru)何快速(su)找到(dao)原因(yin)并進行解決。可能會出現(xian)的(de)原因(yin)以及應對處理方法：

1、中控式塌陷

強夯施工

一般造成這種原因的(de)(de)塌陷多(duo)半是(shi)個(ge)本身的(de)(de)地質是(shi)有關系的(de)(de)，例如一些(xie)丘(qiu)陵地勢，這類地形的(de)(de)土(tu)層比較疏(shu)松，切雨水(shui)較多(duo)，經過多(duo)年的(de)(de)雨水(shui)沖刷，表面上看(kan)見起來雖然沒什(shen)么變(bian)化(hua)，但(dan)是(shi)地層里部(bu)會(hui)有部(bu)分(fen)(fen)的(de)(de)空洞部(bu)分(fen)(fen)，在此(ci)上進行強(qiang)夯施工后，土(tu)質就會(hui)造成坍塌，這種塌陷解決辦法(fa)也非(fei)常(chang)的(de)(de)簡(jian)單，前期做好測量，經過施工后回填土(tu)進行解決就可以了。

2 、水流沖刷塌陷

這個(ge)處(chu)理辦(ban)法很簡單，但(dan)是速度(du)要(yao)快。盡快找到水流的就(jiu)可以的，截(jie)住后積水用水泵(beng)抽掉就(jiu)行。

3 、地質復雜

這種情況其(qi)實(shi)也(ye)是比(bi)較的多見，例如(ru)一些碎石(shi)地帶(dai)，中間摻(chan)雜著一些大(da)塊的石(shi)頭，需要(yao)去除石(shi)頭之后再進行(xing)強夯。這樣(yang)也(ye)會造成一定的塌陷。處理方式(shi)就是回(hui)填土的時候(hou)盡量使(shi)用一些和本地土質接近的方式(shi)進行(xing)回(hui)填。

強夯機安全操作注意事項有(you)哪些？

強夯(hang)機(ji)是(shi)建筑工程施工的(de)設(she)備，太原擠密(mi)樁施工費用，主要用來(lai)對松土(tu)壓實處理(li)。強夯(hang)機(ji)操作的(de)時候有(you)些需要注意(yi)的(de)事項(xiang)，接下(xia)來(lai)我們來(lai)詳細(xi)的(de)介紹一下(xia)。

1、擔任強(qiang)夯工(gong)作的(de)主機(ji)，太原擠密(mi)樁施工(gong)費用多少，應按(an)照強(qiang)夯等級的(de)請求通(tong)過核算選用。用履(lv)帶式(shi)起重機(ji)作主機(ji)的(de)，應履(lv)行履(lv)帶式(shi)起重機(ji)的(de)有關(guan)規定。

2、強(qiang)夯(hang)機(ji)(ji)的工作場所應平坦，門架底座與(yu)夯(hang)機(ji)(ji)著地部位應堅(jian)持水平，當(dang)下沉超越100mm時，應從頭墊高。

3、強夯機(ji)械的門架、橫梁(liang)、脫鉤器(qi)等首(shou)要構造和部(bu)件(jian)的材料及制造質量(liang)，應通過嚴厲查看(kan)，對(dui)不契(qi)合規劃請求(qiu)的，不得運用。

4、工作前強夯機要點查看項目應契合(he)下列請求(qiu)：

1)各(ge)部件銜接好，太原(yuan)擠(ji)密樁(zhuang)施工聯系(xi)方式，無松動。

2)內燃沖擊夯有滿足的潤滑油，油門控制器滾(gun)動靈敏(min)。

3)電(dian)動沖(chong)擊夯(hang)有牢(lao)靠的接零(ling)或接地，電(dian)纜線絕緣無(wu)缺。

5、內(nei)(nei)燃沖擊夯(hang)發(fa)動(dong)后，內(nei)(nei)燃機應(ying)怠速工作(zuo)3—5min，然后逐步加大油門，待夯(hang)機跳動(dong)安穩后，方可(ke)工作(zuo)。

6、電(dian)(dian)動沖擊夯(hang)在接通電(dian)(dian)源(yuan)發(fa)動后，應(ying)查看(kan)電(dian)(dian)動機旋轉方向，有(you)錯(cuo)誤時應(ying)倒換相(xiang)線。

7、夯機(ji)在工作狀況時，起重臂仰角應置于(yu)70°。

8、梯形門架支(zhi)(zhi)腿(tui)不得(de)前后錯(cuo)位，門架支(zhi)(zhi)腿(tui)在(zai)未支(zhi)(zhi)穩墊實(shi)前，不得(de)提錘(chui)。

9、改換(huan)夯位后，應從(cong)頭(tou)查看門架(jia)支腿，承(cheng)認安(an)定牢(lao)靠，然后再將錘提(ti)高100～300mm，查看整(zheng)機(ji)的安(an)穩性，承(cheng)認牢(lao)靠后，方可工作(zuo)。

10、夯錘(chui)(chui)下(xia)落后，在(zai)吊鉤(gou)沒有降(jiang)至(zhi)夯錘(chui)(chui)吊環附近前，太原擠(ji)密樁施工，操作人員(yuan)不得提(ti)(ti)早下(xia)坑掛(gua)鉤(gou)。從坑中(zhong)提(ti)(ti)錘(chui)(chui)時，禁止掛(gua)鉤(gou)人員(yuan)站在(zai)錘(chui)(chui)上隨錘(chui)(chui)提(ti)(ti)高(gao)。

避免鉆(zhan)孔灌注樁護(hu)筒底部(bu)孔壁坍塌措施

　1、質量問題及現象

　孔壁坍塌；鉆(zhan)機傾斜。

　2、原因分析

　1）護(hu)筒底(di)(di)部及(ji)周(zhou)圍未用粘(zhan)土回(hui)填(tian)或夯(hang)實不足，在(zai)鉆進過程(cheng)中或灌注過程(cheng)中泥(ni)漿護(hu)筒底(di)(di)掏空。

　2）由于提供的地(di)質鉆探資料不(bu)祥，使護筒底產處于淤泥或砂層少。

　3）護筒直徑較(jiao)小。

　4）地表水滲入護筒外(wai)圍填土中，造成填土松軟。

避免(mian)鉆孔(kong)灌注樁(zhuang)護筒底(di)部孔(kong)壁坍(tan)塌措施

　3、預防措施

　1）護(hu)筒(tong)底部應(ying)回(hui)填至少50cm厚的粘(zhan)土(tu)(tu)，當土(tu)(tu)質為砂性土(tu)(tu)時(shi)護(hu)筒(tong)周(zhou)圍(wei)0.5-1.0m范圍(wei)內也應(ying)用粘(zhan)土(tu)(tu)回(hui)填并夯實。

　2）根據設計部(bu)門提供的地質資料，護筒底(di)部(bu)應穿(chuan)過淤泥和砂層。

　3）護筒直徑應大于設計孔(kong)徑20-30cm（有(you)鉆桿(gan)的(de)正反循(xun)環鉆）、30-40cm（無鉆桿(gan)的(de)潛(qian)水(shui)電鉆或沖(chong)擊(ji)鉆）。

　4）護(hu)筒出漿(jiang)孔處應用粘土夯(hang)填(tian)，同時(shi)應保持出漿(jiang)順利，周圍(wei)不得有積水，避免護(hu)筒周圍(wei)泥土流失，造成坍孔。
