Firstly, constructing a reactive powder concrete tank bottom: firstly, prefabricating high-strength aluminum alloy splice plates and anti-pulling rings (12) according to design sizes in a factory, paving a tank bottom cushion layer on the site, then binding steel bars at the lower layer of the tank bottom, reserving connecting ribs, pouring active powder concrete (13), arranging a heat preservation layer (24) at the tank bottom after maintenance is finished, arranging a bottom high-strength aluminum alloy splice plate provided with the anti-pulling rings (12) on the heat preservation layer (24), fixing an interlayer heat preservation plate (7) through high-strength bolts (20), pouring concrete to half height inside the bottom high-strength aluminum alloy splice plates, finishing binding of the steel bars at the upper layer and the lower layer of the tank bottom, well connecting the steel bars at the upper layer and the lower layer through the connecting ribs, ensuring that the upper layer concrete and the lower layer concrete form a whole with the heat preservation layer, then pouring the active powder concrete, maintaining and;
Secondly, constructing the tank wall by adopting a layered construction method: firstly, accurately installing an inner plate (6), an outer plate (5) and an interlayer heat-insulation plate (7) on a second layer of the tank wall on an aluminum alloy splice plate extending out of the bottom of the tank, penetrating the inner plate (6), the outer plate (5) and the interlayer heat-insulation plate (7) by using a lengthened anchor bolt connecting piece (9), and determining the distance among the inner plate, the outer plate and the interlayer heat-insulation plate by adjusting the position of a nut; then, pouring stirred common concrete into gaps of an inner plate (6), an interlayer insulation plate (7) and an outer plate (5) layer by a concrete pump, constructing the concrete into the top of a tank wall layer by layer in sequence, arranging a reinforced concrete ring beam (23) on the top of the tank wall, connecting prefabricated annular steel pipe active powder concrete composite members through steel web members to form a vertical annular steel pipe active powder concrete composite truss (8), placing the vertical annular steel pipe active powder concrete composite truss (8) in the reinforced concrete ring beam (23), sleeving an anti-skid steering rubber ring (15) on the annular steel pipe active powder concrete members, and adjusting the position; then binding a reinforcement cage of the reinforced concrete ring beam;
Thirdly, construction of orthogonal cable beams: prefabricating a high-strength spring steel pipe (3) and a cable pipe intersection connecting steel node (14) in a factory, installing the high-strength spring steel pipe and the cable pipe intersection connecting steel node on site, penetrating a cable from a cable way (17) through a reserved cable way (17) of the cable pipe intersection connecting steel node (14), accurately penetrating all cables of an orthogonal cable beam into the node, and then installing a high-strength spring steel pipe pressure lever to realize reliable connection with the node; adjusting the height of the tank top, penetrating an unbonded cable through an anti-skid steering rubber ring (15), reserving a certain length, pouring active powder concrete to the top of the tank wall, applying prestress to a suspension cable system to tension control stress after curing to reach a certain strength, firstly tensioning a stabilizing cable (1) and a bearing cable (2) in one direction, anchoring the bearing cable (2) at the top end of the tank wall through the direction conversion of a vertical annular steel pipe active powder concrete composite truss (8), anchoring the stabilizing cable (1) at the inner side of the top of the tank wall through the direction conversion of the vertical annular steel pipe active powder concrete composite truss (8), then tensioning the stabilizing cable (1) and the bearing cable (2) in another direction, secondarily tensioning the first tensioned stabilizing cable and the bearing cable after anchoring, supplementing prestress loss caused by tensioning in the other direction, finally, sealing the anchor to finish the construction of the tank wall;
Fourthly, arranging a high-strength aluminum alloy reinforcing ring (10) at a designed position on the inner side of the top of the tank wall to enhance the transverse stability of the tank wall structure, and meanwhile, installing a roof support ring (11) on the inner side of the top of the tank wall to enhance the stability of a PDCPD roof panel (4) on the tank top, thereby being beneficial to the drainage of an oversized storage tank adopting orthogonal cable beams as the tank top;
fifthly, tank top construction: connecting a prefabricated T-shaped steel plate support (18) with bolt holes with all cable pipe intersection connecting steel nodes (14), then laying a PDCPD roof panel (4), and reliably connecting an upper cover plate (19), the PDCPD roof panel (4) and the T-shaped steel plate support (18) through high-strength bolts (20); and (3) supporting the PDCPD roof panel on a roof support ring (11) near the tank wall to finish the construction of the tank top.
