Pipeline construction method adopting bubble-mixed lightweight soil backfilling method
The invention discloses a pipeline construction method adopting a bubble-mixed lightweight soil backfilling method. The pipeline construction method comprises the steps of: S1, construction preparation; S2, trench excavation; S3, pipe foundation construction; S4, pipe installation; S5, bubble-mixed lightweight soil backfilling; and S6, maintenance of bubble-mixed lightweight soil. The S2 comprisesthe laying of impermeable geotextiles, and the S5 comprises the laying of galvanized steel wire mesh, defoaming test, lightweight soil flow value detection and lightweight soil wet bulk density detection. The invention provides a pipeline construction method adopting the bubble-mixed lightweight soil backfilling method. Using the backfilling process of the scheme, equipment occupies a small construction area for pouring, the bubble-mixed lightweight soil has high fluidity and solidifies quickly after pouring without mechanical grinding, pressing or vibrating, and the effects of simple construction and compactness of the backfilling can be achieved.
本发明公开了气泡混合轻质土回填法管道施工工法，包括以下步骤：S1，施工准备；S2，沟槽开挖；S3，管基施工；S4，安管；S5，气泡混合轻质土回填；S6，气泡混合轻质土的养护；其中，S2步骤中包括防渗土工模铺设作业，S5步骤中包括镀锌钢丝网铺设作业，消泡试验，轻质土流值检测和轻质土湿容重检测。本发明提供了气泡混合轻质土回填法管道施工工法，采用本方案的回填工艺，设备占浇筑施工面积小，气泡混合轻质土具有高流动性，浇筑完后自行快速固化且不需机械碾压或振捣，可达到施工简便且能回填密实的效果。
