鋼波紋涵管(guan)路堤法的工(gong)藝流程為:施工(gong)前準(zhun)備—施工(gong)放(fang)樣—設置圍(wei)堰(yan)—排(pai)水清(qing)淤—平整(zheng)場(chang)地—檢測(ce)(ce)(ce)壓實度(du)(du)、含(han)水量(liang)等(deng)(deng)—水準(zhun)測(ce)(ce)(ce)量(liang)—平整(zheng)場(chang)地—基礎(chu)分層(ceng)回(hui)(hui)填—檢測(ce)(ce)(ce)壓實度(du)(du)含(han)水量(liang)等(deng)(deng)—水準(zhun)測(ce)(ce)(ce)量(liang)—平整(zheng)場(chang)地—施工(gong)方樣—拼裝管(guan)節—檢測(ce)(ce)(ce)密水情況及(ji)管(guan)底(di)縱坡—檢測(ce)(ce)(ce)并補救(jiu)防腐涂層(ceng)—涵管(guan)就位——兩側分層(ceng)回(hui)(hui)填—檢測(ce)(ce)(ce)壓實度(du)(du)、含(han)水量(liang)等(deng)(deng)—進出口(kou)處理。
鋼(gang)波紋涵(han)管(guan)在(zai)2019年的工作重點在(zai)哪里?
涵(han)洞施工前應(ying)根據具體情況修筑(zhu)相應(ying)長度的施工便道,并合理組織(zhi)過往車(che)輛。涵(han)洞施工前必(bi)須對(dui)到(dao)現場的涵(han)管節及(ji)其(qi)(qi)附屬配件進行檢(jian)(jian)測(ce),一方(fang)面檢(jian)(jian)測(ce)其(qi)(qi)結構尺寸是(shi)否(fou)滿足要(yao)求,另(ling)一方(fang)面檢(jian)(jian)測(ce)其(qi)(qi)表面防腐(fu)是(shi)否(fou)達(da)到(dao)要(yao)求;必(bi)要(yao)時(shi)須在鍍鋅涂層表面在增涂瀝青或其(qi)(qi)他(ta)防腐(fu)材料。
鋼波紋涵管反開槽回填法涵(han)洞(dong)施(shi)(shi)工(gong)(gong)前備(bei)齊(qi)所需材料。涵(han)洞(dong)施(shi)(shi)工(gong)(gong)前應準備(bei)涵(han)洞(dong)施(shi)(shi)工(gong)(gong)過(guo)程(cheng)中試驗。檢測儀器和(he)設備(bei),落實試驗人員。金(jin)屬(shu)波紋(wen)涵(han)管(guan)路堤法涵(han)洞(dong)施(shi)(shi)工(gong)(gong)前施(shi)(shi)工(gong)(gong)單(dan)位需要通(tong)知(zhi)監理(li)及相關人員到場(chang),并按程(cheng)序(xu)辦理(li)施(shi)(shi)工(gong)(gong)前的手(shou)續。
涵管施工前應設(she)一名管道安裝(zhuang)指(zhi)揮人(ren)員,負責指(zhi)揮吊裝(zhuang)及施工人(ren)員的(de)(de)現(xian)場操作;設(she)置1~2名技(ji)術人(ren)員負責放線。涵管安置等控(kong)制(zhi)關(guan)鍵技(ji)術;同時配置適(shi)當的(de)(de)輔助人(ren)員。涵洞施工前應備(bei)齊所(suo)需的(de)(de)機械設(she)備(bei)及相關(guan)工具,反開槽回填法的(de)(de)工藝流程為。
鋼波紋涵管(guan)洞(dong)施(shi)(shi)(shi)工(gong)工(gong)藝流程(cheng)可分(fen)為路(lu)堤法(fa)和反開槽(cao)回(hui)填(tian)法(fa),由于后(hou)者涵洞(dong)的(de)施(shi)(shi)(shi)工(gong)多(duo)在路(lu)基施(shi)(shi)(shi)工(gong)結束(shu)后(hou)和改建涵洞(dong),所(suo)以不影響路(lu)基施(shi)(shi)(shi)工(gong)整(zheng)體進度,一般后(hou)者較為多(duo)見。盡管(guan)在外力上二者存在一定的(de)差異(yi),但施(shi)(shi)(shi)工(gong)工(gong)藝相差不大(da)。下面分(fen)別予以敘述。
