Step S2, concrete material preparation: the cement, sand and stone raw materials are screened, an expanding agent is doped into the concrete, and the alkali content, the water cement ratio, the concrete slump and the initial setting and final setting time of the concrete are controlled.

Wherein, the cement is ordinary Portland cement R42.5; the sand is natural medium coarse sand, the average grain diameter is not less than 0.3mm, and the mud content is less than 3.0%; the stones are selected from stones with compact structure, high strength, grain size not more than 40mm, mud content less than 10% and water absorption less than 1.5%; the alkali content of the concrete is required to meet the relevant management regulations, and the limit value of the total alkali content is required to be 3kg/m 3; the water-cement ratio of the concrete is not more than 0.55; the concrete slump is controlled to be between 140mm and 180mm, the horizontal component is controlled to be 140mm +/-20 mm, and the vertical component is controlled to be 160mm +/-20 mm; the initial setting time of the concrete is controlled to be 1-3 h, and the final setting time of the concrete is controlled to be 12-16 h.

Step S3, the reinforcing band 102 sets: a plurality of criss-cross reinforcing belts 102 are arranged on the bottom plate 103, the wall body and the top plate of the tank body 1. The reinforcing band 102 is sealed by adopting a fast and easy closing net, and is firmly supported by adopting reinforcing steel bars, so that the pouring requirements of the bottom plate 103, the wall body and the top plate are met, and the subsequent pouring construction of the reinforcing band 102 is facilitated.

Step S4, the post-cast strip 103 sets: and a post-cast strip 103 is arranged between the adjacent pouring sub-cabins 104.

Wherein, the concrete pouring of the bottom plate 103 adopts the continuous pouring process of thin layer pouring, gradual and gradual, gradual and uniform rising and one-time top reaching. Adopt the inclined plane layering when pouring, control layering thickness for 300mm ~ 400mm (according to bottom plate 103 thickness layering, no longer than 400 mm) with layering scale pole, according to 1: the slope of 6 is impelled forward to according to the slope that forms when pouring, arrange two vibration points, the first is arranged at the concrete discharge point, and the second is arranged in concrete bevel department. After the concrete is poured and vibrated to be compact, the construction is carried out by adopting a one-time plastering process, and the surface is plastered and pressed by a 2m scraping bar before the initial setting of the concrete to drive off the surface bleeding. Before the concrete is finally set, a wooden trowel is used for rubbing and leveling, and then an iron trowel is used for trowelling and pressing for 2-3 times, so that the shrinkage of surface layer concrete is reduced, and surface shrinkage cracks are prevented.

Before the concrete of the wall is poured, the stone-reducing cement mortar with the thickness of 50mm and the same proportion as the concrete of the wall is uniformly paved at the joint of the wall. The mortar is placed into the mortar groove and is uniformly distributed into the mould manually, so that a pump pipe is not needed to be directly poured into the mould. When the concrete of the wall body is poured in a layered mode, a layered scale rod is manufactured to control the layered blanking thickness of the concrete, and the layered pouring thickness is about 50 cm. The concrete is vibrated by adopting an inserted vibrating rod, and when the concrete is poured in layers, the vibrating rod is inserted into the lower layer by 50mm so as to eliminate the seam between the two layers.

Wherein, should lay the construction packway before the concrete placement of roof, its width is not less than 800mm to can guarantee operating personnel's construction road, prevent to trample the reinforcing bar, guarantee the protective layer thickness of the accurate roof reinforcing bar in position of bent reinforcing bar, in time demolish after concrete placement. When concrete of the top plate is poured, the pre-measurement of the mark pile is scaled, and the thickness is checked by drawing an elevation control line with a small white line according to a control point marked by a red adhesive tape on a reinforcing steel bar of the wall body. The concrete of roof should be laid thickness slightly be greater than the roof thickness, with the vibration of flat vibrator round trip, should be in the same direction of pouring when using the vibrting spear drag the vibration, the angle control is suitable at 60 degrees, strickle off with 3m long bar according to the elevation control line after waiting to vibrate to finish to guarantee surface smoothness, and trowel before initial set. Meanwhile, in order to prevent the concrete of the top plate from generating shrinkage cracks, a 2m scraping bar is used for scraping the concrete to the middle of the plate along the wall root of the four-side wall before the initial setting of the concrete, and a wooden trowel is used for rubbing and compacting for 2 to 3 times before the final setting of the concrete, so that the concrete is ensured to be flat.

Step S7, film coating and maintenance: after the initial setting of the concrete, the coating curing is carried out before the final setting. The concrete curing film is tightly combined with the surface of the concrete during film covering, so that the hydration effect of the concrete is promoted, the obvious effects of cracking prevention and moisture preservation are achieved, and the possibility of leakage of the water pool is further reduced.
