管幕-箱涵顶进施工技术造价编制要点分析

Analysis on Key Points of Cost Compilation of Pipe Curtain-Box Culvert Jacking Construction Technology

管幕-箱涵顶进施工法是除盾构法、矿山法之外的地下结构施工工艺,主要应用于穿越河流、铁路、高速公路等地下通道工程。由于其对地面交通影响少、覆土浅等优势,所以在国内、外有较多的工程案例,如上海市中环线北虹路下立交等项目。但是,其管幕段尚无造价编制标准。依据管幕-箱涵顶进施工工艺流程、项目组成内容等,在分析其造价组成内容的基础上,提出造价编制要点,供今后类似工程在编制设计概算、施工图预算、工程量清单、招标控制价及投标报价时参考。

The pipe curtain-box culvert jacking construction method is an underground structure construction technology other than the shield method&the mine method,which is mainly used in underground passage projects such as crossing rivers,railways,&highways.Due to its advantages of less impact on ground transportation&shallow soil coverage,there are more engineering cases at home and abroad,such as the Shanghai Mid-Ring Beihong Rd.Underpass,etc.However,there is no cost standard for the pipe curtain section.According to the construction process&project composition of pipe curtain-box culvert jacking,based on the analysis of its cost composition,it puts forward the key points of cost compilation for reference in the preparation of design budget,construction drawing budget,bill of quantities,bidding control price&bidding price of similar projects in the future.
