冬季(ji)施工不能忽視的關鍵點(dian)

冬季天氣寒冷，施(shi)工困難(nan)，同時又臨近年底和春節，一些施(shi)工企業經常會(hui)忘掉(diao)安全(quan)而(er)一味地搶進度求效益，這是安全(quan)事故多(duo)發癥結所在。冬季施(shi)工要注意以下九個(ge)方面的(de)問題：

1、強化工期管控

為(wei)確保工(gong)(gong)期，一(yi)些施(shi)(shi)工(gong)(gong)單位往往出現不(bu)具(ju)備施(shi)(shi)工(gong)(gong)條件(jian)就開工(gong)(gong)的問題(ti)，從而導致施(shi)(shi)工(gong)(gong)過(guo)程(cheng)中(zhong)的蠻干(gan)、濫干(gan)。一(yi)些施(shi)(shi)工(gong)(gong)單位，為(wei)了搶(qiang)進(jin)度不(bu)注重安(an)全管理，在安(an)全設施(shi)(shi)不(bu)齊備的情況下進(jin)行施(shi)(shi)工(gong)(gong)，存在僥幸心理。

結(jie)果(guo)事故發生后(hou)，員(yuan)工受到傷(shang)害，機械設備遭到破(po)壞，工地整(zheng)頓，非(fei)但(dan)進度上不去，反而會耽誤了工期。

進(jin)度(du)依賴于(yu)安全(quan)(quan)，安全(quan)(quan)推動(dong)著進(jin)度(du)，進(jin)度(du)服從(cong)于(yu)安全(quan)(quan)，安全(quan)(quan)反過來保證進(jin)度(du)。

2、強化現場(chang)防凍防滑管理

遇到雨雪(xue)天(tian)氣(qi)，要(yao)及時清(qing)除施(shi)(shi)工(gong)(gong)現(xian)場的積(ji)水積(ji)雪(xue)。加強(qiang)從(cong)業人員冬季施(shi)(shi)工(gong)(gong)的御寒防護，作業人員必(bi)須采取有效的防滑措施(shi)(shi)，嚴(yan)禁雨雪(xue)和大風(feng)天(tian)氣(qi)組織室外施(shi)(shi)工(gong)(gong)作業。

對施工(gong)現場腳(jiao)(jiao)手(shou)(shou)架、安全網等防護設(she)施要定期檢查。腳(jiao)(jiao)手(shou)(shou)架、腳(jiao)(jiao)手(shou)(shou)板有冰雪積留時，施工(gong)前(qian)應(ying)清除(chu)干凈，尤(you)其是連墻件(jian)和竹笆層的(de)檢查，山(shan)西(xi)擠(ji)密(mi)樁施工(gong)廠家，松動的(de)扣件(jian)要及時擰緊(jin)，破損(sun)的(de)竹笆應(ying)立(li)即更(geng)換。腳(jiao)(jiao)手(shou)(shou)架拆除(chu)要嚴格按照規定程序，不(bu)得隨意拆除(chu)。

擠(ji)密(mi)(mi)(mi)樁(zhuang)基施(shi)(shi)(shi)(shi)工(gong)(gong)，灰土(tu)(tu)擠(ji)密(mi)(mi)(mi)樁(zhuang)施(shi)(shi)(shi)(shi)工(gong)(gong)，環保擠(ji)密(mi)(mi)(mi)樁(zhuang)施(shi)(shi)(shi)(shi)工(gong)(gong)，水(shui)泥(ni)土(tu)(tu)擠(ji)密(mi)(mi)(mi)樁(zhuang)施(shi)(shi)(shi)(shi)工(gong)(gong)，素(su)土(tu)(tu)擠(ji)密(mi)(mi)(mi)樁(zhuang)施(shi)(shi)(shi)(shi)工(gong)(gong)，夯擴擠(ji)密(mi)(mi)(mi)樁(zhuang)施(shi)(shi)(shi)(shi)工(gong)(gong)，沉管擠(ji)密(mi)(mi)(mi)樁(zhuang)施(shi)(shi)(shi)(shi)工(gong)(gong)，強夯地基施(shi)(shi)(shi)(shi)工(gong)(gong)，碎石擠(ji)密(mi)(mi)(mi)樁(zhuang)施(shi)(shi)(shi)(shi)工(gong)(gong)，擠(ji)密(mi)(mi)(mi)螺(luo)紋樁(zhuang)施(shi)(shi)(shi)(shi)工(gong)(gong)，鉆孔灌注樁(zhuang)施(shi)(shi)(shi)(shi)工(gong)(gong)，軟土(tu)(tu)地基施(shi)(shi)(shi)(shi)工(gong)(gong)，灰土(tu)(tu)樁(zhuang)施(shi)(shi)(shi)(shi)工(gong)(gong)，我(wo)公司主營：擠(ji)密(mi)(mi)(mi)樁(zhuang)施(shi)(shi)(shi)(shi)工(gong)(gong)，擠(ji)密(mi)(mi)(mi)樁(zhuang)工(gong)(gong)程(cheng)

素土夯(hang)填(tian)，夯(hang)實(shi)機械(xie)為2T強夯(hang)機，人工(gong)回填(tian)。

依據試驗室出(chu)具的素土擊實報告控制現場含(han)水率。

夯實(shi)機械就位后，夯錘對準孔心，先夯實(shi)孔底(di)2次，再用黃土(tu)進(jin)行人(ren)工(gong)(gong)回填，每(mei)填入0.5m3 土(tu)料(liao)，夯擊3次，重錘提(ti)升高(gao)度5m。依此從(cong)下往(wang)上進(jin)行，山(shan)西(xi)擠密樁施(shi)工(gong)(gong)報價，單樁施(shi)工(gong)(gong)過程中，做好填料(liao)量，成樁時(shi)間記錄。

樁基(ji)檢測.由建(jian)設單(dan)位委(wei)托(tuo)的符合(he)相關資質和要求的檢測單(dan)位進行樁基(ji)檢測，并出(chu)具合(he)法、有效的檢測報告。

素土擠密樁施(shi)工質(zhi)量標準:樁位平(ping)面(mian)位置誤差(cha)70mm內。定位放線后(hou)機械成(cheng)孔，檢查(cha)成(cheng)孔深(shen)度是否滿足要求(qiu)，機械配合人工分(fen)層回填，夯填時(shi)重錘提升高(gao)度為5m，允許誤差(cha)-300mm。回填土選(xuan)用(yong)黃土，有機料不(bu)得超(chao)過3%，土徑不(bu)大于15mm。
