管道试压和回填要尽量安排在停雨期间进行，并且排尽沟内积水。管道清理后，要尽快组织试压和回填。如来不及试压，可将焊口两侧各1米位置留出，其余位置全部回填，防止管道漂浮。Aftercleantheinsideoftrench,thepipelinepressuretestandtrenchbackfillwillbeperformedassoonaspossible.Ifaftertrenchcleaning,thetestcan’tbeperformtimely,trenchbackingwillbedonefirst.And1meteronbothsideofweldingjointwillbeleftwithoutbackfill.5.4.1.1过马路埋地管施工：所有从马路或水沟下面穿过的埋地消防管，应尽量在马路施工前完成。如马路先施工，有埋地管穿过的地方应协调预留，预留宽度以管道中心两侧各500mm，待埋地管道回填后再施工。Pipeacrosstheroad:allthefirefightingwaterpipingwhichwillacrosstheroaddrainwillbedonebeforeroadanddrainconstruction.Iftheroadconstructionstart,shallwaitforpipingfirstthepipecrossingportion.5.4.2管道焊接5.4.2.1管道焊接采用手工焊（氩弧焊打底，电弧焊填充盖面），采用“V”型坡口，其尺寸见下表，管道对口时应使内壁齐平，错口偏差为0.2t，且不得大于1.5mm；Manualweldingshallbeusedforpipewelding(RootGTAW,capSMAW).Thejointsofthepipeshallbeevenness.Thetoleranceis0.2tbutnotmorethan2mm.GrooveshallbeinthetypeofV.thesizeisasfollows.表5-3table5-3壁厚（mm）thickness间隙（mm）clearance错边（mm）stagger坡口角度α（°）groove4-91.5-3.01.0-1.560-7010-262.0-4.01.560±55.4.2.2焊接材料：氩弧打底采用H08Mn2SiA焊丝，焊条采用J422焊条。Weldingmaterial:H08Mn2SiAforGTAW;J422forSMAW.5.4.2.3钢管对口检查合格后可以进行点焊，点焊采用与接口相同的焊接材料，点焊时对称施焊，厚度与第一层焊接厚度一致，钢管的纵向焊缝与螺旋焊缝处不得点焊。点焊长度及间距符合下表。Tackweldingshallbedoneafterjointofthesteelpipegotcheckedandapproved.Weldingshallbeusedsameweldingmaterialasjoint.Symmetryweldingshallbedonewellinspotwelding.Thethicknessshallbethe
