種樹施工方案

/越南福和閘堰項(xiàng)目植樹施工方案中國水利水電建設(shè)集團(tuán)國際工程有限公司越南福和閘堰項(xiàng)目部二○一一年九月十五日1、概述及主要工程量越南福和閘堰項(xiàng)目植樹面積49.27公頃。分布于左岸進(jìn)場道路旁邊，業(yè)主管理房四周，和土壩下游區(qū)域。2、施工工藝流程及主要施工方法施工工藝流程：表（層）面處理→測量定位→挖種植穴→樹苗檢查→植樹→養(yǎng)護(hù)。2.1表（層）面處理：須要植樹的部位用推土機(jī)大致推平，鏟除表面的雜草，灌木等影響樹木生長的雜物。2.2定點(diǎn)放樣測量人員進(jìn)行定點(diǎn)的放樣，嚴(yán)格依據(jù)一公頃面積植樹440棵放樣（即植樹間距4.77米），測量后做明顯標(biāo)記。2.3挖種植穴：種植穴直徑60cm，深度為60cm，要求坑壁光滑，上下面口徑基本一樣。2.4樹苗檢查樹干挺直，沒有明顯彎曲，無蛀干害蟲和未愈合的機(jī)械損傷；樹冠豐滿，枝條分布勻整、無嚴(yán)峻病蟲危害，樹葉正常；根系發(fā)育良好、無嚴(yán)峻病蟲危害；土球大小為苗木胸徑的10倍以上。2.5植樹種植的質(zhì)量標(biāo)準(zhǔn)：種植的苗木品種為景觀樹柚樹，苗木的本身和地面垂直，沒有傾斜；嚴(yán)格依據(jù)測量定點(diǎn)種植，橫平豎直，樹木應(yīng)在一條直線上；樹苗高度為1.5米左右，相鄰兩株高差不超過30cm；種植深淺和原土痕持平；保持樹苗土球完好，包裝物應(yīng)取出。種植的程序和方法：樹木入穴后，土球放穩(wěn)，樹干直立，拆除并取出包裝物；種植后在樹木四周筑成高5－10cm的灌水土堰，便利澆水；種植后須要支撐的樹木，用樹枝或者竹竿支撐堅(jiān)實(shí)，使樹木保持直立；新植樹木24小時(shí)內(nèi)澆第一遍水，三日內(nèi)澆其次遍水，十日內(nèi)澆上第三遍水，三遍水后轉(zhuǎn)入后期養(yǎng)護(hù)；每次澆水后均整堰、堵漏、培土、扶直樹干，第三遍水后封堰。2.6養(yǎng)護(hù)：新植樹苗完成后進(jìn)行養(yǎng)護(hù)，主要項(xiàng)目包括：澆水、、防治病蟲、補(bǔ)栽未成活樹苗、直至交付驗(yàn)收。3、施工設(shè)備及人員配置3.1施工設(shè)備序號機(jī)械設(shè)備名稱規(guī)格型號單位數(shù)量備注1自卸汽車10t臺12推土機(jī)SD23臺13水泵2寸臺54全站儀PENTAX臺1R-322NX5水桶/只若干6鋤頭/把若干7鐵锨/把若干3.2主要勞動力配置主要勞動力配置表序號工種數(shù)量（人）備注1自卸汽車駕駛員12推土機(jī)駕駛員13測量工44普工25合計(jì)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.2.5PlantingQualityStandard：Thecategoryofthesaplingtoplantisteakaslandscapetrees.Thesaplingitselfshouldbeplatedverticallytowardthelandwithoutanyslant.Thetreesshouldbeplantedstrictlyaccordingtothesettingoutpoints,orderedinrowsandlineswithtreesonastraightline;theheightofthesaplingshouldbeabout1.5mandtheheightdifferencebetweensaplingsshouldbenolargerthan30cm;theplantingdepthshouldbeleveledwiththesurroundingearth;thesoilballofthesaplingshouldbefinelykeptwithoutanypackingmaterial.PlantingProcessandMethod：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-
