电缆槽作业施工要求
电缆槽作业施工要求
Construction Requirements for Cable Channel Operation
施工准备
Construction preparation
施工前对振捣平台等设备的运转情况进行检查，对施工人员的岗位资格进行核实。运至预制现场的砂、碎石、水泥、钢筋等原材料要进行抽样检验。施工场地及电缆槽成品存放场地建设完成。
Before construction, check the operation of vibration platform and other equipment, and verify the qualifications of construction personnel. The raw materials such as sand, gravel, cement and steel bars transported to the prefabricated site shall be sampled and inspected. Construction site and storage site for finished products of cable trough have been completed.

1、钢筋加工
1. Processing of Reinforcement Bars
按设计施工图《铁路路基电缆槽》图号：通路（2010）8041的设计要求对进场合格的钢筋进行下料加工。并对下料的钢筋尺寸、规格验收，合格后方可使用。
According to the design and construction drawing "Railway Subgrade Cable Channel" drawing number: access (2010) 8041 design requirements for the entry grid of steel cutting processing. After acceptance of the size and specifications of the steel bars, they can be used only after they are qualified.
2、模板加工
2. Template Processing
根据设计施工图《铁路路基电缆槽》图号：通路（2010）8041的电缆槽结构尺寸形式及现场施工用的电缆槽形式加工电缆槽硬塑料定型模具。电缆槽模具进场验收合格后方可使用，在使用过程中随时检查模具是否损坏，如有损坏清除淘汰。
According to the drawing number of "Railway Subgrade Cable Slot": the cable groove structure size form of 8041 channel (2010) and the cable groove form used in field construction, the rigid plastic mould for cable groove is processed. Cable groove dies can be used only after they have passed the acceptance test. In the process of using, check whether the dies are damaged at any time, and eliminate the damages if they are eliminated.
3、钢筋安装
3. Reinforcement Installation
电缆槽钢筋在钢筋加工场地绑扎完成（模外绑扎），电缆槽模具进场经验收合格后并清理干净，脱模剂涂刷均匀后。将电缆槽钢筋整体装入电缆槽模具中，并调整保护层间距直至满足设计及规范要求。
The cable groove reinforcement is tied up at the steel bar processing site (outside the mould binding). The cable groove die is cleaned after qualified entry experience, and the stripping agent is uniformly painted. The cable groove reinforcement is integrated into the cable groove die, and the spacing of the protective layer is adjusted until the design and specification requirements are met.
4、混凝土浇筑
4. Concrete pouring
电缆槽钢筋安装完成后，经质检工程师及监理验收合格后，浇筑混凝土。混凝土采用现场拌合的方式，振捣采用平板振捣器制作的振动台振捣，一般振捣时间控制在3-4min（根据现场实际可适当调整），不得过振。混凝土入模具分三层入模振捣，保证电缆槽内实外光。混凝土外露模具部分采用人工抹光压实。
After the installation of cable groove reinforcement is completed, concrete is poured after the quality inspection engineer and supervision acceptance are qualified. The concrete is mixed on site, and the vibration table is made of flat plate vibrator. The vibration time is generally controlled at 3-4 minutes (which can be adjusted properly according to the actual situation on site), so it can not overshoot. The concrete injection mould is divided into three layers and vibrated to ensure the solid and external light in the cable groove. Artificial polishing and compaction are used in the part of concrete exposed mould.
