种树施工方案

越南福和闸堰项目植树施工方案中国水利水电建设集团国际工程有限公司越南福和闸堰项目部二○一一年九月十五日1、概述及主要工程量越南福和闸堰项目植树面积49.27公顷。分布于左岸进场道路旁边，业主管理房周围，和土坝下游区域。2、施工工艺流程及主要施工方法施工工艺流程：表（层）面处理→测量定位→挖种植穴→树苗检查→植树→养护。2.1表（层）面处理：需要植树的部位用推土机大致推平，铲除表面的杂草，灌木等影响树木生长的杂物。2.2定点放样测量人员进行定点的放样，严格按照一公顷面积植树440棵放样（即植树间距4.77米），测量后做明显标记。2.3挖种植穴：种植穴直径60cm，深度为60cm，要求坑壁光滑，上下面口径基本一致。2.4树苗检查树干挺直，没有明显弯曲，无蛀干害虫和未愈合的机械损伤；树冠丰满，枝条分布均匀、无严重病虫危害，树叶正常；根系发育良好、无严重病虫危害；土球大小为苗木胸径的10倍以上。2.5植树2.5.1种植的质量标准：种植的苗木品种为景观树柚树，苗木的本身与地面垂直，没有倾斜；严格按照测量定点种植，横平竖直，树木应在一条直线上；树苗高度为1.5米左右，相邻两株高差不超过30cm；种植深浅与原土痕持平；保持树苗土球完好，包装物应取出。2.5.2种植的程序和方法：树木入穴后，土球放稳，树干直立，拆除并取出包装物；种植后在树木四周筑成高5－10cm的灌水土堰，方便浇水；种植后需要支撑的树木，用树枝或者竹竿支撑牢固，使树木保持直立；新植树木24小时内浇第一遍水，三日内浇第二遍水，十日内浇上第三遍水，三遍水后转入后期养护；每次浇水后均整堰、堵漏、培土、扶直树干，第三遍水后封堰。2.6养护：新植树苗完成后进行养护，主要项目包括：浇水、、防治病虫、补栽未成活树苗、直至交付验收。3、施工设备及人员配置3.1施工设备序号机械设备名称规格型号单位数量备注1自卸汽车10t台12推土机SD23台13水泵2寸台54全站仪PENTAX台1R-322NX5水桶/只若干6锄头/把若干7铁锨/把若干3.2主要劳动力配置主要劳动力配置表序号工种数量（人）备注1自卸汽车驾驶员12推土机驾驶员13测量工44普工25合计31Contract1APhuocHoaHeadworksConstructionMethodforTreePlantingSeptember15th20111、GeneralincludingmainconstructionquantitiesThetreeplantingareafortheVietnamPhuocHoaheadworksoccupied49.27hamainlydistributedattwosidesoftheleftbankaccessroad,thesurroundingoftheEmployer’smanagementhouseandthedownstreamareaoftheearthdam.2、ConstructionProcessandMainMethodConstructionProcess:SurfaceTreatment→Surveyforpositioning→PitExcavation→CheckingoftheSapling→Planting→Maintenance2.1SurfaceTreatment：Leveltheplantingareabybulldozer,andremovetheweedsandbushesatthesurfacewhichwillimpactthegrowingofthetrees.2.2SettingOutSettingoutbythesurveystaff,strictlykeepingthespacingby4.77mbasedon440treesperha,andmakemarksaftersettingout.2.3ExcavationofthePlantingPits：Theplantingpitswillbeexcavatedwithdia60cmand60cmofdepth,withsmoothwalls,consistentdimensionsfortheopeningandthebottompart.2.4CheckingoftheSaplingSaplingshouldbestraightbody,noobviousbending,noharmbytheinsectsorphysicalsurfaceinjury;richcrownwithevenlydistributedbrancheswithoutanydiseaseorharmfulinsects,withhealthyleaves;grownrootwithoutanydiseaseorharmfulinsects;soilballshouldbe10timeslargerthanthediameterofthebreastbranchofthesapling.2.5Planting2.5.1QualityStandard：Thecategoryofthesaplingtoplantisteakaslandscapetrees.Thesaplingitselfshouldbeplatedverticallytowardthelandwithoutanyslant.Thetreesshouldbeplantedstrictlyaccordingtothesettingoutpoints,orderedinrowsandlineswithtreesonastraightline;theheightofthesaplingshouldbeabout1.5mandtheheightdifferencebetweensaplingsshouldbenolargerthan30cm;theplantingdepthshouldbeleveledwiththesurroundingearth;thesoilballofthesaplingshouldbefinelykeptwithoutanypackingmaterial.2.5.2PlantingProcessandMethod：Aftersaplingsareburiedinthepit,thesoilballshouldbesteadywithuprightbranchafterremovalofthepacking;earthridgearoundthesaplingswillbebuiltat5to10cmheighttomakewateringeasier;forthetreewhichneedstobesupportedafterplanted,usingbranchesorbamboosticksforenhancingtokeepthesaplingstraight;firstwateringshouldbecarriedoutwithin24hrsforthenewplantedsapling,secondwateringiswithin3days,thirdwateringiswithin10days,lastmaintenanceperiodwillbecarriedoutafterthethirdtimewatering.Earthridgearoundthetreeshouldbedonetrim,sealwaterlose,earthbackinganduprightsupportduringeverywatering,andearthridgewillbesealedafterthethirdtimewatering.2.6Maintenance：Themaintenanceworksforthenewplantedsaplingswillbecarriedoutaftertheyareputintotheplantingpit.Themaintenanceworksconsistofcontinuingwatering,diseaseandinsectcontrol,secondtimeplantforthefailuresaplings,untildelivery.3、ArrangementoftheMachinesandLaborForce3.1ConstructionMachinesNo.MachineItemSpecificationUnitQtyRemarks1DumpTruck10tSet12BulldozerSD23Set13Pump2寸Set54TotalStationPENTAXSet1R-322NX5WaterBarrel/pcsmanyNo.MachineItemSpecificationUnitQtyRemarks6Hoe/PcsMany7Shovel/pcsMany3.2MainDistributionoftheLaborTableoftheMainLaborsNo.ItemNumbersRemarks1DumpTruckDriver12BulldozerDriver13SurveyStaff44Labor25Total31
