浅析排水管道土方量计算要点

A Discussion of Earthwork Volume Calculation Key Points of Drainage Pipelines

排水工程设施的完善反映一个城镇现代化程度的高低,排水工程的投资很大程度上影响着整个市政项目的经济效益。开槽施工是排水管道施工的常用工艺之一,在管道工程施工中,沟槽土方工作主要包括沟槽开挖、支护、回填等,工作量占整个工程很大比重,因此选择合理的开挖、支护以及回填料对施工质量及投资有直接影响,研究基于排水土方工程对造价的影响。

Status of drainage facilities reflects the level of modernization of a city.Economic benefits of public works are greatly influenced by drainage engineering investment.Taking a large proportion of workload in the whole project,trench excavation is one of the most common process in drainage pipeline construction during which groove and earthwork mainly include groove excavation,excavation support and backfill.It is important to choose reasonable excavation methods,support style and backfill materials that can put direct impact on construction quality and investment.This paper focused on the research of the influence on project cost made by drainage and earthwork engineering.
