Working well bagged filler and manufacturing method thereof
The invention discloses a working well bagged filler and a manufacturing method thereof, and relates to the technical field of electric power engineering, the working well bagged filler comprises a packaging bag and a sand grain, powder grain, clay grain and fly ash mixture contained in the packaging bag, and the weight ratio of the sand grain to the powder grain to the clay grain to the fly ash in the mixture is (0.55-0.6): (0.25-0.3): (0.08-0.12): (0.04-0.06). The working well bagged filler has the advantages that the working environment in the well where the power cable is located is converted into the direct burial laying environment outside the well through the method of filling the special filler, and the bagged filler is convenient to use, easy to put in and take out and high in safety; the reasonable raw material ratio realizes that the water absorption rate of the filler is lower than or close to the water absorption rate of soil around a working well, the water permeability of the filler is higher than the water permeability of the soil around the working well and lower than the water permeability of natural sand, and meanwhile, the filler has a proper heat conductivity coefficient.
本发明公开了一种工作井袋装填料及其制作方法，涉及电力工程技术领域，工作井袋装填料包括包装袋及装在包装袋内的沙粒、粉粒、粘粒和粉煤灰混合物，混合物中沙粒、粉粒、粘粒和粉煤灰的重量比为(0.55～0.6):(0.25～0.3):(0.08～0.12):(0.04～0.06)。本发明的优点在于：工作井袋装填料通过填充特殊填料的方法将电力电缆所处的井内工作环境转换为井外直埋敷设环境，袋装填料使用方便，易于放入和取出，且安全性高；合理的原料配比实现了填料吸水率低于或接近工作井周边泥土的吸水率，填料透水性高于工作井周边泥土的透水性且低于天然沙子的透水性，同时具有合适的导热系数。
