Construction method for mounting groove body of electric power prefabricated pipe gallery
The invention relates to the technical field of civil engineering, and discloses an electric power prefabricated pipe gallery installation groove body construction method which comprises the following steps that S1, after an excavator is used for grooving and tamping, a C30 concrete cushion layer with the thickness being 10-12 cm is poured; s2, a datum line is marked through a laser gradienter, mounting holes with the interval being 3 m are drilled, and the bottom frame is placed and aligned; s3, the cross nails are reserved in the mounting holes, and the chassis track is fixed through an automatic nailing machine; s4, baffles are placed on the two sides of the bottom frame, concrete is poured for fixing, and the baffles are dismantled after solidification; and S5, the calandria is installed through a crane, and the track system is calibrated after the calandria is fixed through a torque wrench. The thickness of the cushion layer is controlled, the C30 high-strength concrete is adopted, the flatness and bearing capacity of the cushion layer are remarkably improved, the problems of cushion layer sedimentation and non-uniformity caused by sand fluidity are solved, and therefore the overall stability of the pipe gallery system is improved, and the risk of sedimentation or displacement caused by unbalanced stress of the calandria is avoided.
本发明涉及土木工程技术领域，公开了电力预制管廊安装槽体施工方法，包括以下步骤：S1、使用挖掘机挖槽并夯实后，浇筑厚度为10‑12cm的C30混凝土垫层；S2、用激光水平仪标记基准线，并钻设间距为3m的安装孔，放置底架并对齐；S3、将十字交叉钉预留在安装孔，使用自动打钉机固定底架轨道；S4、在底架两侧放置挡板并浇筑混凝土固定，待凝固后拆除挡板；S5、使用起重机安装排管，并用扭矩扳手固定后校准轨道系统。通过控制垫层厚度并采用C30高强度混凝土，显著提高了垫层的平整度和承载力，解决了因沙子流动性导致的垫层沉降和不均匀问题，从而提高了管廊系统的整体稳定性，避免了排管因不均衡受力而发生沉降或位移的风险。
