市政管网工程沟槽开挖支护方式的造价对比分析

Cost Comparison and Analysis of Trench Excavation and Support Methods in Municipal Pipeline Network Engineering

目前,市政管网工程建设越来越重要,而控制工程投资是市政管网工程的重要内容。文章研究了某城市的一个河流区域雨污分流工程,在保障项目质量和施工安全的基础上,对比了不同的开挖方式,同时对比了在相同开挖深度下,各种支护方式对应的沟槽开挖工程成本。研究结果表明,市政道路下沟槽开挖选用支护方式更为经济,可为业内市政管网工程造价控制及投资决策提供借鉴。

Currently,the construction of municipal pipeline network engineering is becoming increasingly important,and controlling project investment is an important part of municipal pipeline network engineering.The article studied a rainwater and sewage diversion project in a river area of a certain city.Based on ensuring project quality and construction safety,different excavation methods were compared,and the cost of trench excavation corresponding to various support methods was compared at the same excavation depth.The research results indicate that the use of support methods for excavation of trenches under municipal roads is more economical and can provide reference for cost control and investment decision-making in municipal pipeline network engineering in the industry.
