Construction method of volute layer concrete flat pouring
The invention discloses a construction method of volute layer concrete flat pouring. The method adopts flat pouring method and symmetrical cutting and comprises the following steps: preparation beforeconstruction, concrete surface treatment, steel reinforcement manufacturing and installation, embedded parts installation, water stop installation, formwork Installation, concrete pouring, demouldingand concrete curing. The concrete is divided into at least two parts by adding a distribution device at an outlet of a distributor, and the volute layer is poured evenly at a plurality of points, andthe concrete pouring height is evenly increased. The invention adopts the flat-pouring method and symmetrical cutting for pouring, when the volute layer is poured, a plurality of points are uniformlycut at the same time, so that the concrete rises uniformly at the same time, and the pouring of the entire volute layer can be completed at the same time, without the layered pouring during a pouringprocess, a plurality of times of waiting is not required, and the construction time is shorter than that of layered pouring. In addition, symmetrical cutting is used for pouring, and the concrete haspouring joints that exist in layered pouring, so the method has no safety hazards.
本发明公开了一种蜗壳层混凝土平浇施工方法,采用平浇法对称下料，其步骤如下：施工前准备、混凝土表面处理、钢筋制安、预埋件安装、止水带安装、模板安装在、混凝土浇筑、拆模和混凝土养护。通过在布料机的出口增设分料装置，将混凝土分成至少两份，在蜗壳层浇筑时多点均匀下料，混凝土浇筑高度均匀上升。本发明采用平浇法对称下料进行浇筑，在蜗壳层浇筑时多点均匀同时下料，从而使得混凝土同时均匀上升均匀浇筑，可以同时完成整个蜗壳层的浇筑，无需在浇筑过程中进行分层浇筑，中间不用进行多次等待，相比分层浇筑的施工时间较短。而且采用对称下料浇筑，混凝土不会出现分层浇筑所存在的浇筑缝，从而不会有安全隐患。
