Pipeline excavation construction method
The invention provides a pipeline excavation construction method. The pipeline excavation construction method comprises the following steps of positioning and paying off, accurately measuring and paying off a pipeline center line, driving timber piles for marking, leading out a steel sheet pile driving side line from each side of the pipeline center line according to drawing requirements, spraying a lime line as a steel sheet pile driving positioning line, and leading out the positioning line at the two ends by using the timber piles; inserting and driving the steel sheet piles, accurately measuring and setting the position of the first steel sheet pile, clamping the steel sheet piles by adopting a pile driver, completing pile insertion in a vertical state, and inserting and driving the steel sheet piles; a steel sheet pile supporting assembly is arranged between the steel sheet piles on the two sides of the center line of the pipeline for fixed supporting; excavation is carried out, surface soil cleaning is carried out before excavation, and trench excavation is carried out by adopting an excavator from top to bottom horizontally in a segmented and layered mode; by the adoption of the pipeline excavation construction method, the side slope of the foundation pit is blocked through the steel sheet piles, destructive displacement of the side slope can be prevented, and safety of the surrounding environment and normal construction are guaranteed.
本发明提供一种管道开挖施工方法，包括以下步骤：定位放线，准确测放出管道中心线，打设木桩标明，从管道中心线每边按图纸要求引出钢板桩施打边线，洒出石灰线作为钢板桩施打的定位线，并在两端用木桩将定位线引出；钢板桩插打，精确测设第一根钢板桩的方位，采用打桩机夹起钢板桩呈垂直状态下完成插桩并对钢板桩进行插打；钢板桩支撑，在管道中心线两侧的钢板桩之间设置钢板桩支撑组件进行固定支撑；开挖，开挖之前先进行表土清理，沟槽开挖采用挖掘机自上而下水平分段分层进行；采用本发明中的管道开挖施工方法，通过钢板桩对基坑的边坡进行阻挡，能够防止边坡产生破坏性位移，保证周边环境安全及施工正常进行。
