鋼波紋(wen)涵(han)管(guan)路堤(di)法的工藝流程為:施(shi)(shi)工前準備(bei)—施(shi)(shi)工放樣—設置圍堰—排(pai)水(shui)清(qing)淤(yu)—平整場(chang)地(di)(di)—檢(jian)測(ce)(ce)壓(ya)實度、含(han)水(shui)量(liang)等—水(shui)準測(ce)(ce)量(liang)—平整場(chang)地(di)(di)—基礎分層(ceng)回填—檢(jian)測(ce)(ce)壓(ya)實度含(han)水(shui)量(liang)等—水(shui)準測(ce)(ce)量(liang)—平整場(chang)地(di)(di)—施(shi)(shi)工方(fang)樣—拼裝(zhuang)管(guan)節—檢(jian)測(ce)(ce)密水(shui)情況及(ji)管(guan)底(di)縱坡(po)—檢(jian)測(ce)(ce)并補救防腐涂層(ceng)—涵(han)管(guan)就位——兩側分層(ceng)回填—檢(jian)測(ce)(ce)壓(ya)實度、含(han)水(shui)量(liang)等—進出口(kou)處理。
鋼波(bo)紋涵管在(zai)2019年的(de)工作重(zhong)點在(zai)哪里?
涵洞施工(gong)前應根據具體情況修筑(zhu)相應長度(du)的(de)施工(gong)便道,并合理組(zu)織過(guo)往車輛。涵洞施工(gong)前必須對到現場的(de)涵管節及其附屬配件進行檢(jian)(jian)(jian)測(ce),一方面檢(jian)(jian)(jian)測(ce)其結構(gou)尺(chi)寸是否滿足要(yao)求,另一方面檢(jian)(jian)(jian)測(ce)其表(biao)面防(fang)腐是否達到要(yao)求;必要(yao)時須在(zai)(zai)鍍鋅(xin)涂(tu)層表(biao)面在(zai)(zai)增涂(tu)瀝(li)青或其他防(fang)腐材料。
鋼波紋涵管反開槽回填(tian)法(fa)涵洞(dong)施(shi)工(gong)前(qian)備(bei)齊所需材料。涵洞(dong)施(shi)工(gong)前(qian)應準備(bei)涵洞(dong)施(shi)工(gong)過程中試(shi)驗。檢測儀器和(he)設備(bei),落(luo)實試(shi)驗人員(yuan)。金(jin)屬波紋涵管(guan)路(lu)堤(di)法(fa)涵洞(dong)施(shi)工(gong)前(qian)施(shi)工(gong)單位(wei)需要通(tong)知監理及相關人員(yuan)到場,并按程序(xu)辦(ban)理施(shi)工(gong)前(qian)的手續。
涵(han)管施(shi)(shi)工(gong)前應(ying)設一名(ming)管道安裝指揮人(ren)(ren)員(yuan),負責指揮吊裝及施(shi)(shi)工(gong)人(ren)(ren)員(yuan)的(de)現場操作;設置(zhi)1~2名(ming)技(ji)(ji)術人(ren)(ren)員(yuan)負責放線。涵(han)管安置(zhi)等控制關鍵技(ji)(ji)術;同(tong)時配置(zhi)適(shi)當的(de)輔助人(ren)(ren)員(yuan)。涵(han)洞(dong)施(shi)(shi)工(gong)前應(ying)備齊所需(xu)的(de)機(ji)械設備及相關工(gong)具(ju),反開槽回填(tian)法(fa)的(de)工(gong)藝流(liu)程為。
鋼波紋涵(han)管洞施(shi)工(gong)工(gong)藝(yi)流(liu)程可分為路(lu)(lu)(lu)堤(di)法(fa)和反開槽回(hui)填法(fa),由于后者涵(han)洞的施(shi)工(gong)多(duo)在路(lu)(lu)(lu)基施(shi)工(gong)結束(shu)后和改建涵(han)洞,所以不影響路(lu)(lu)(lu)基施(shi)工(gong)整(zheng)體進度,一般后者較為多(duo)見。盡管在外力上二(er)者存在一定的差異,但(dan)施(shi)工(gong)工(gong)藝(yi)相(xiang)差不大。下面分別予以敘述。
