Collapsible loess double-row pipeline groove earthwork self-balancing excavation method
The invention discloses a collapsible loess double-row pipeline groove earthwork self-balancing excavation method. The method comprises the following steps that a construction site is divided into sections; each section is constructed according to the working procedures S1, S2, S3 and S4; the method comprises the steps that S1, excavation is conducted in a layered mode from top to bottom, earthwork used for foundation treatment is reserved, and excavation and outward transportation are not conducted in a trench; s2, soil is reserved in the step S1, scarification, mixing and rolling treatment are conducted, and the compaction degree meets the design requirement; s3, the pipeline is hoisted to a groove to be installed and welded, quality inspection is carried out, and the next procedure is carried out after the pipeline is qualified; and S4, earthwork backfilling and rolling are conducted, and the compaction degree meets the design requirement. According to the method, excavation can be conducted in the collapsible loess area, additional sinking is prevented, meanwhile, the complexity of earthwork balance calculation is simplified, repeated earthwork transfer is reduced, the engineering precision is improved, the excavation efficiency of the large pipeline groove is improved, and the construction period is shortened.
本发明公开了一种湿陷性黄土双排管道沟槽土方自平衡开挖方法，包括以下步骤：对施工现场进行区段划分；每一区段均按S1、S2、S3、S4工序进行施工；其中，S1、采用自上而下的方法分层进行开挖，并预留基础处理所用土方，在沟槽内部，不进行开挖、外运；S2、将S1预留土方，进行翻松、拌合、碾压处理，使压实度达到设计要求；S3、将管道吊装至沟槽安装、焊接，并进行质量检查，合格后进入下道工序；S4、将土方回填、碾压，使压实度达到设计要求。本发明能够在湿陷性黄土区域开挖，防止附加下沉，同时简化土方平衡计算的复杂性，减少土方反复倒运，提高工程的精度，提高大型管道沟槽开挖工效，缩短工期。
