建筑经济CONSTRUCTIONECONOMY第44卷第S1期2023年7月Vol.44No.S1Jul.2023摘要:为应对建筑工人短缺,推进电站绿色施工,小断面TBM在抽水蓄能电站排水廊道和自流排水洞得到广泛运用。与常规TBM使用场景相比,抽水蓄能电站地下洞室具有洞径小、距离短、孤段多、转弯急、坡度大的特点。现在的水电定额体系中缺少相关子目,而且水利工程及市政工程中的定额与抽水蓄能电站的特点不相匹配。本文以5个正在使用小断面TBM施工的电站为样本,现场测定施工消耗量,为预算定额编制提供借鉴。关键词:小断面TBM;补充定额;消耗量;投资对比中图分类号:TU723.3文献标识码:A文章编号:1002-851X(2023)S1-0111-04DOI:10.14181/j.cnki.1002-851x.2023S1111ResearchonExcavationConsumptionof3.5-meterDiameterTBMintheConstructionofPumpedStorageDrainageCorridorZHANGJumei1,DAIHonghui2,ZHANGYunfei3,ZHUDequan4(1.StateGridXinyuanHoldingCo.,Ltd,Beijing100052,China;2.HuadongEngineeringCo.,Ltd,Hangzhou311100,China;3.ChinaQualityCertificationCentre,Nanjing210019,China;4.ZhejiangNinghaiPumpedStorageCo.,Ltd,Ningbo315000,China)Abstract:Inordertocopewiththeshortageofconstructionworkersandpromotethegreenconstructionofpowerstations,small-sectionTBMiswidelyusedindrainagecorridorsandgravitydrainagetunnelsofpumpedstoragepowerstations.ComparedwiththeconventionalTBMapplicationscenario,theundergroundcavernofpumpedstoragepowerstationhasthecharacteristicsofsmalltunneldiameter,shortdistance,manyisolatedsections,sharpturnandlargeslope.Thecurrenthydropowerquotasystemlacksrelevantsub-items,andthequotasinwaterconservancyprojectsandmunicipalprojectsdonotmatchthecharacteristicsofpumpedstoragepowerstations.Inthispaper,fivepowerstationsunderconstructionwithsmallcross-sectionTBMaretakenassamples,andtheconstructionconsumptionismeasuredonthespot,whichprovidesreferenceforbudgetquotacompilation.Keywords:smallcross-sectionTBM;supplementaryquota;consumption;investmentcomparison1引言截至2022年11月15日,“十四五”期间已核准抽水蓄能电站共计43个,装机规模合计5709.8万千瓦,抽水蓄能开发建设速度明显加快。此时,二十大报告对我国生态文明建设提出一系...
