Construction method and structure of porous mass concrete easy to dissipate heat and cool
The invention discloses a porous mass concrete construction method and structure easy for heat dissipation and cooling, the construction method is combined with the characteristic of layered pouring of mass concrete, a plurality of hollow channel molds of each layer are vertically arranged at the construction front edge of the concrete of each layer, and the channel molds are 20-30 cm higher than the concrete surface and serve as heat dissipation channels communicated with the outside; concrete hydration heat is transferred into air, the highest temperature in a concrete structure and the internal and external temperature difference are reduced, the mass concrete temperature control condition is improved, then the concrete cracking risk is reduced, the engineering quality is guaranteed, the concrete warehousing temperature standard is reduced, the aggregate cooling cost investment is reduced, the temperature control cost is reduced, and the overall carbon emission is reduced. Meanwhile, due to the formed porous structure, the use amount of mass concrete materials can be remarkably reduced, in the construction process, a pore channel mold does not need to be dismantled, the construction process is reduced, and the construction efficiency is higher.
本发明公开了一种易于散热降温的多孔大体积混凝土施工方法及结构，施工方法结合大体积混凝土分层浇筑特点，在每层混凝土施工前沿竖向布设该层的多根内空的孔道模具，孔道模具高出混凝土面20～30cm，作为与外界连通的散热通道，混凝土水化热传递至空气中，降低混凝土结构内最高温度和内外温差，改善了大体积混凝土温控情况，进而降低混凝土开裂风险，保证工程质量，降低混凝土入仓温度标准，减少骨料冷却费用投入，降低温控成本，整体降低碳排放量，更利于工程建设绿色低碳发展，同时，形成的多孔结构可显著减少大体积混凝土材料用量，在施工过程中，孔道模具无需拆除，减少了施工流程，施工效率更高。
