Construction method of large-span groove-crossing protection facility of important pipeline
The invention discloses a construction method of a large-span groove-crossing protection facility of an important pipeline, and relates to the technical field of pipeline groove-crossing protection facility construction methods. In order to improve the construction safety, the construction process is simplified. The construction method of the large-span groove-crossing protection facility comprises the following steps that construction preparation is conducted on a protection component; lower support primary and secondary keels and an upper steel truss component are blanked and prefabricated; earth at two sides of a concrete slab is pre-excavated; holes are pre-dug in the bottom of the concrete slab; the lower support secondary keel is perforated in place; the lower support main keel is installed; the upper steel truss is installed and fixed; and a lower support supporting system is tightened. In the process of laying the plain concrete slabs, the earth around the plain concrete slabs is excavated in a manual and small machine tool excavation mode, and after the earth is excavated to the elevation required by the design, a small tamping machine is used for tamping and compacting the earth, so that a stable operation platform can be formed, the earth at the two sides of the pipeline is manually pre-excavated, and the pipeline can be kept stable in the excavation process.
本发明公开了一种重要管线大跨度跨槽保护设施的施工方法，涉及管线跨槽保护设施施工方法技术领域；为了提高施工的安全性，简化施工工艺；该种大跨度跨槽保护设施的施工方法包括以下步骤：对保护组件进行施工准备；下托主次龙骨、上部钢桁架构件下料、预制；混凝土板两侧土方预挖；混凝土板底预挖孔洞；下托次龙骨穿孔就位；下托主龙骨安装；上部钢桁架安装固定；收紧下托支承体系。本发明在对素混凝土板进行铺设的过程中，素混凝土板周围的土方开挖采用人工加小型机具开挖的方式，开挖至设计要求标高后，使用小型打夯机将土体夯压密实，从而可以形成稳定操作平台，对管线两侧土方进行人工预开挖，可以确保管线开挖过程中保持稳定。
