我国几个大型水泥厂的共同特点是设备由外引进;厂房和构筑物由国内设计和施工。水泥贮仓结构一般都选用钢筋混凝土大直径圆形筒仓,随之带来一个重要而不被人注意的贮仓屋盖防水问题,是值得研究探讨的。冀东水泥厂6座水泥筒仓顶部防水问题的处理就是一例。该厂的6座水泥筒仓内径18m,高46m,每仓容量1.25万t,筒仓为捣制钢筋混凝土结构。仓壁厚350cm,仓顶盖为1.5m高的工字钢梁6根,上铺80mm厚的预制板,其上再捣制60mm厚的钢筋混凝土板,板上抹20mm厚的砂浆找平层,上铺
The common feature of several large-scale cement plants in China is the introduction of equipment from outside; the plant and structures are designed and constructed by the country. The cement silo structure generally uses reinforced concrete large-diameter circular silos, which brings with it an important and unobtrusive problem of waterproofing the silo roof. It is worthy of study and discussion. One example is the treatment of the waterproof problem at the top of six cement silos in Jidong Cement Factory. The 6 cement silos of the plant have an internal diameter of 18m, a height of 46m and a capacity of 12500t per silo. The silo is made of reinforced concrete structure. The wall thickness of the warehouse is 350cm. The top cover of the warehouse is 1.5m high I-beams. The 80mm-thick prefabricated plate is overlaid. The 60mm-thick reinforced concrete slabs are smashed and the plate is wiped with a 20mm thick mortar screed. Overlay
