在經歷了今年6月份上、中旬多輪降雨影響之后,端午節期間的降雨仍然在對湖南長沙、婁底、懷化、湘潭、益陽等市州施加影響。同樣在混凝土施工方面下雨天氣一方面容易造成道路泥濘,另一方面因山體開挖過程中又容易造成山石松動,造成塌方及泥石流等現象,給工程施工安全帶來極大隱患。部分施工場地位于開挖山體上,容易造成積水,導致局部浸泡,三民重科在此提醒砼工程必(bi)須采(cai)取以(yi)下(xia)適當的措施,以(yi)確保工(gong)程施工(gong)正常運行(xing)。
1、在(zai)不影(ying)響(xiang)工(gong)(gong)(gong)期的前(qian)提下,盡量(liang)(liang)把砼(tong)工(gong)(gong)(gong)程(cheng)安排在(zai)晴(qing)天進行(xing)(xing)(xing)施工(gong)(gong)(gong); 2、砼(tong)工(gong)(gong)(gong)程(cheng)在(zai)雨(yu)(yu)天施工(gong)(gong)(gong)時(shi),運輸途中需加以(yi)(yi)(yi)(yi)遮蓋,防(fang)(fang)止(zhi)雨(yu)(yu)水進入,并隨時(shi)檢(jian)查模板(ban)(ban)支撐(cheng)的強(qiang)度及(ji)(ji)其穩(wen)(wen)定(ding)性(xing); 3、模板(ban)(ban)隔離層在(zai)涂刷前(qian)要(yao)及(ji)(ji)時(shi)掌握天氣(qi)(qi)預報,以(yi)(yi)(yi)(yi)防(fang)(fang)隔離層被(bei)雨(yu)(yu)水沖走; 4、遇到大(da)雨(yu)(yu)停止(zhi)澆(jiao)筑砼(tong),已澆(jiao)部(bu)位(wei)加以(yi)(yi)(yi)(yi)覆(fu)蓋; 5、雨(yu)(yu)期施工(gong)(gong)(gong)時(shi),加強(qiang)對砼(tong)粗(cu)骨(gu)細料含水量(liang)(liang)的測定(ding),及(ji)(ji)時(shi)調(diao)整用水量(liang)(liang); 6、大(da)面(mian)積砼(tong)澆(jiao)筑前(qian),了解2-3天的天氣(qi)(qi)預報,盡量(liang)(liang)避開大(da)雨(yu)(yu)。砼(tong)澆(jiao)筑現場要(yao)預備(bei)防(fang)(fang)雨(yu)(yu)材(cai)料,以(yi)(yi)(yi)(yi)便澆(jiao)筑時(shi)突然遇雨(yu)(yu)進行(xing)(xing)(xing)覆(fu)蓋; 7、模板(ban)(ban)支撐(cheng)下回填要(yao)夯實,并加好(hao)墊板(ban)(ban),雨(yu)(yu)后及(ji)(ji)時(shi)檢(jian)查有無(wu)下沉; 8、下雨(yu)(yu)時(shi)不得進行(xing)(xing)(xing)鋼筋焊接、對接等工(gong)(gong)(gong)作,急需時(shi)做(zuo)好(hao)防(fang)(fang)雨(yu)(yu)工(gong)(gong)(gong)作或(huo)將施工(gong)(gong)(gong)場所移至室內進行(xing)(xing)(xing);剛焊好(hao)的鋼筋接頭(tou)部(bu)位(wei)應防(fang)(fang)雨(yu)(yu)水澆(jiao)淋(lin),以(yi)(yi)(yi)(yi)免接頭(tou)驟冷發生脆裂影(ying)響(xiang)建筑物質量(liang)(liang); 9、砼(tong)基礎澆(jiao)筑完(wan)畢,要(yao)立即(ji)排出未回填的基坑中的水,以(yi)(yi)(yi)(yi)免地基浸泡失(shi)穩(wen)(wen);對已經(jing)拆模的基坑要(yao)及(ji)(ji)時(shi)回填并夯實。對新(xin)澆(jiao)筑的基礎須(xu)架設防(fang)(fang)雨(yu)(yu)棚。
