柳州地(di)處我國南部，屬亞熱帶季風(feng)氣候區，雨(yu)季一般始于(yu)4月(yue)下旬，終于(yu)9月(yue)上旬，年總降(jiang)(jiang)雨(yu)量約1345～1940毫米，是(shi)全(quan)國降(jiang)(jiang)水量最豐(feng)富(fu)的地(di)區之一。雨(yu)季施(shi)工(gong)(gong)是(shi)項目(mu)必須經歷的施(shi)工(gong)(gong)階段，施(shi)工(gong)(gong)安全(quan)、排水系(xi)統(tong)、便道、混凝土穩定性等問(wen)題(ti)都需要全(quan)面(mian)統(tong)籌考慮(lv)。針對(dui)雨(yu)季施(shi)工(gong)(gong)所面(mian)臨(lin)的問(wen)題(ti)，項目(mu)結合實際情(qing)況(kuang)采取一系(xi)列有效的管理措施(shi)，確(que)保順利完成年度(du)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(zai)內業(ye)方面，項(xiang)(xiang)目(mu)有針(zhen)對性地(di)開(kai)展(zhan)安(an)全(quan)生產宣傳教育活動，明確強調雨季安(an)全(quan)施(shi)工注意事項(xiang)(xiang)，和(he)勞務工人簽訂(ding)安(an)全(quan)風(feng)險告知(zhi)書，確保現場施(shi)工人員掌握安(an)全(quan)生產要點(dian)，進一步提高作業(ye)人員的自我(wo)安(an)全(quan)防(fang)范意識和(he)能(neng)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。
在雨季(ji)來(lai)臨前，項目組織人(ren)員(yuan)對施工(gong)(gong)(gong)現場進行(xing)全面勘測，并根據(ju)實(shi)際情況制定排(pai)(pai)(pai)水(shui)(shui)方案，設專人(ren)負責排(pai)(pai)(pai)水(shui)(shui)工(gong)(gong)(gong)作(zuo)，確(que)保雨水(shui)(shui)能快(kuai)速排(pai)(pai)(pai)出(chu)，減(jian)少降(jiang)雨對施工(gong)(gong)(gong)帶(dai)來(lai)的不利(li)影(ying)響。項目部(bu)分路(lu)(lu)段處(chu)于低洼地(di)帶(dai)，周邊(bian)農(nong)田密(mi)布、水(shui)(shui)系發達，既要(yao)確(que)保順利(li)施工(gong)(gong)(gong)，也(ye)要(yao)防止(zhi)農(nong)田被雨水(shui)(shui)淹沒(mei)，對汛期排(pai)(pai)(pai)水(shui)(shui)泄洪(hong)的要(yao)求較高。為解決這一難(nan)題，項目進一步完善(shan)排(pai)(pai)(pai)水(shui)(shui)系統(tong)，修筑急流槽將水(shui)(shui)排(pai)(pai)(pai)出(chu)路(lu)(lu)基，加(jia)強(qiang)排(pai)(pai)(pai)水(shui)(shui)溝(gou)、邊(bian)溝(gou)修筑施工(gong)(gong)(gong)，使排(pai)(pai)(pai)水(shui)(shui)溝(gou)與邊(bian)溝(gou)接通周邊(bian)水(shui)(shui)系，確(que)保施工(gong)(gong)(gong)場地(di)的排(pai)(pai)(pai)水(shui)(shui)渠道暢通，同時也(ye)幫助村民改善(shan)農(nong)田水(shui)(shui)利(li)灌溉條件。
