Pipeline groove excavation and backfill construction method based on in-situ curing of wall protection slurry
The invention discloses a pipeline groove excavation and backfill construction method based on in-situ curing of retaining wall slurry, which comprises the following steps: excavating a groove on a current road while injecting slurry into the groove and enabling the liquid level of the slurry to be always positioned on the bottom surface of the road surface of the current road, the groove is excavated to the designed elevation; hoisting and lowering a pipe section to a preset position in the groove, and enabling the slurry liquid level to be always positioned on the bottom surface of the pavement of the current road; a curing agent is added into the slurry in the groove, and the curing agent and the slurry are stirred and mixed to form flow-state solidified soil; and after the flow-state solidified soil is hardened and reaches the design strength, a road recovery pavement is constructed on the hardened flow-state solidified soil. The method has the advantages that the earthwork outward transportation work amount is reduced, construction is convenient and fast, the groove backfilling quality is reliable, and the engineering cost is saved.
本发明公开了一种基于护壁泥浆原位固化的管道沟槽开挖回填施工方法，所述施工方法包括以下步骤：边在现状道路上开挖沟槽开挖边往所述沟槽内注入泥浆并使所述泥浆液面始终位于所述现状道路的路面底面，直至所述沟槽开挖至设计标高；将管段吊装下放至所述沟槽内的预设位置处并使所述泥浆液面始终位于所述现状道路的路面底面；在所述沟槽内的泥浆中添加固化剂并将所述固化剂与所述泥浆进行搅拌混合，以形成流态固化土；待所述流态固化土硬化并达到设计强度后，在硬化的所述流态固化土上施作道路恢复路面。本发明的优点是：具有减少土方外运工程量、施工方便快捷、沟槽回填质量可靠、节约工程成本等特点。
