A construction method of a geopolymer air film concrete suction bucket foundation specifically comprises the following steps:
firstly, prefabricating a suction bucket foundation 1; prefabricating a bucket skirt 2 and a subdivision plate 3 of a suction bucket foundation 1 on land, and fixing the bucket skirt 2 and the subdivision plate 3 in a welding mode to form an inner subdivision 4;
secondly, preliminarily constructing a dome structure of the top cover 5; landing the bottom end of the suction bucket foundation 1, sealing the top of the suction bucket foundation 1 by using an air film, and inflating the air film into the inner compartment 4 to form an outward convex dome structure;

Example two
The difference between this embodiment and the first embodiment is that after the construction according to the construction sequence of the air film layer, the polyurethane layer 7, the reinforcing steel bar layer 8 and the geopolymer concrete layer is completed, in order to improve the overall strength of the structure, the construction of the reinforcing steel bar layer 8 and the geopolymer concrete layer can be continued on the basis of this construction, so that the overall thickness of the structure is controlled within the range of 20cm-50cm, and the reinforcing steel bars of the plurality of reinforcing steel bar layers need to be arranged in a staggered manner. Therefore, the situation that the tensile strength of the geopolymer concrete layer is reduced due to the fact that the thickness of the geopolymer concrete layer to be sprayed is thick and the spraying time is long when the geopolymer concrete layer is constructed can be avoided. And meanwhile, the risk that the polyurethane layer 7 cracks or collapses due to the increase of the load borne by the polyurethane layer 7 in a short time can be avoided. And after the geopolymer concrete layer is sprayed, the construction of the reinforcing steel bar layer 8 and the geopolymer concrete layer is continued, the sprayed geopolymer concrete layer can reach certain strength, and the above risks are not easy to occur when the construction of the geopolymer concrete layer is carried out.
The invention replaces the traditional rigid inner support by the air film support, replaces the conventional segmental casting mode by the concrete spraying mode, and replaces the conventional portland cement concrete by the geopolymer concrete, thereby effectively reducing the construction cost, shortening the construction period, improving the construction efficiency, shortening the construction period and reducing the pollution and influence of the construction period on the environment.
