柳州地(di)處(chu)我國(guo)(guo)南部，屬亞熱(re)帶季風(feng)氣候區，雨(yu)(yu)季一(yi)般始于4月下旬，終(zhong)于9月上旬，年(nian)總降(jiang)雨(yu)(yu)量約1345～1940毫米，是全(quan)(quan)國(guo)(guo)降(jiang)水量最豐(feng)富(fu)的地(di)區之一(yi)。雨(yu)(yu)季施(shi)工(gong)(gong)是項目(mu)必須經(jing)歷的施(shi)工(gong)(gong)階段(duan)，施(shi)工(gong)(gong)安全(quan)(quan)、排水系統、便道、混(hun)凝土穩定性等問題都需要全(quan)(quan)面(mian)統籌考慮。針對雨(yu)(yu)季施(shi)工(gong)(gong)所面(mian)臨(lin)的問題，項目(mu)結合實(shi)際情(qing)況(kuang)采取一(yi)系列有(you)效的管理措施(shi)，確保順利完成年(nian)度施(shi)工(gong)(gong)任務。
項目根據《關于做好2020年清明節、“五一”勞動節期間安全生產工作的通知》（路建二司發〔2020〕46號）文件要求，由安全部牽頭，各工區積極配合，在清明節前后深入施工現場、工區駐地、勞務隊駐地開展安全隱患排查工作。
在外業方面，項目重點排查電箱責任名牌、電纜線鋪設、大型機械設備用電等情況，輸電線路嚴格實行“三相五線”制和三級配電二級保護的要求，用電設備落實“一機一閘一漏一箱”制，為機電設備設置防雨棚，確保用電安全。項目邊坡地質類型多為炭質泥巖，穩定性較差，易造成邊坡失穩、塌方。項目采取對存在塌方隱患的邊坡設置臨時攔水梗，坡頂設置截水溝，在上邊坡采取拱形骨架鋪筑等防止邊坡受到沖刷的措施，同時加強地質不良地段的沉陷觀測，做好相關防護措施，防止雨水浸泡基坑。項目還詳細排查工區、勞務隊駐地，對危險建筑以及重點建筑進行加固，處于危險地段的建筑予以搬遷。
在內業方面，項目有針對性地開展(zhan)安(an)全生產宣(xuan)傳教育活動，明確強調雨季安(an)全施工(gong)注(zhu)意事項，和(he)勞務工(gong)人(ren)(ren)簽訂安(an)全風險告(gao)知書，確保現場施工(gong)人(ren)(ren)員掌握(wo)安(an)全生產要(yao)點，進一步提(ti)高(gao)作業人(ren)(ren)員的自(zi)我(wo)安(an)全防(fang)范意識和(he)能力。
雨季期間，便道就是確保順利施工的重要通道。項目將便道和排水系統結合施工總平面圖統一布置，充分利用隧道洞渣修繕主線便道，確保雨季施工主線便道暢通，為雨季期間運輸材料、搶抓結構物提供保障。
在雨(yu)(yu)季來臨前，項目(mu)(mu)組(zu)織人員對施(shi)工(gong)現場進行(xing)全面勘(kan)測(ce)，并根據實際情況制定排(pai)水(shui)(shui)(shui)(shui)方案，設專人負責排(pai)水(shui)(shui)(shui)(shui)工(gong)作，確(que)保雨(yu)(yu)水(shui)(shui)(shui)(shui)能快速排(pai)出，減(jian)少降雨(yu)(yu)對施(shi)工(gong)帶(dai)來的不利影(ying)響(xiang)。項目(mu)(mu)部分路段處于低(di)洼(wa)地(di)帶(dai)，周邊(bian)(bian)(bian)農田(tian)密布、水(shui)(shui)(shui)(shui)系(xi)發達，既要(yao)確(que)保順利施(shi)工(gong)，也要(yao)防止農田(tian)被雨(yu)(yu)水(shui)(shui)(shui)(shui)淹沒，對汛期排(pai)水(shui)(shui)(shui)(shui)泄洪的要(yao)求較高(gao)。為解決這一難題，項目(mu)(mu)進一步完(wan)善(shan)排(pai)水(shui)(shui)(shui)(shui)系(xi)統，修筑急流(liu)槽(cao)將水(shui)(shui)(shui)(shui)排(pai)出路基，加強排(pai)水(shui)(shui)(shui)(shui)溝(gou)、邊(bian)(bian)(bian)溝(gou)修筑施(shi)工(gong)，使排(pai)水(shui)(shui)(shui)(shui)溝(gou)與(yu)邊(bian)(bian)(bian)溝(gou)接通周邊(bian)(bian)(bian)水(shui)(shui)(shui)(shui)系(xi)，確(que)保施(shi)工(gong)場地(di)的排(pai)水(shui)(shui)(shui)(shui)渠道(dao)暢(chang)通，同(tong)時也幫助村民改善(shan)農田(tian)水(shui)(shui)(shui)(shui)利灌溉條件。
