Embodiment Construction

[0012] figure 1 Middle (1), (2), (3), (4), (5), (6), (7)... represent the construction layer; (A), (B), (C), (D), (E), (F)...represent the construction section.

[0013] Such as figure 1 Shown, the present invention divides construction layer and construction section according to setting time and strength of concrete,

[0014] 1. The height of the construction layers (1), (2), (3), (4), (5), (6), (7) and other construction layers is equal to the thickness of the wall board.

[0015] 2. In order to facilitate construction and ensure the continuity of pouring, divide the construction sections (A), (B), (C), (D), (E), (F) and other construction sections according to the time specified in Table 1.

[0016] 3. Bind the bottom plate and wall steel bars at the same time.

[0017] 4. Complete the construction of wall panels and floor formwork.

[0018] 5. After pouring the bottom slab concrete, pour the concrete layered and segmented evenly and symmetrically around the wall slab....

Abstract

The invention relates to a continuous casting method of concrete in the liquid storage structure, belonging to the on-site casting technique of construction wall, that continuously casting the wall plate and the bottom plate, to shorten the construction period. Said method comprises that: first, casting the bottom plate concrete, and bonding the bottom plate and wall plate steel bar, to complete the constructions of the moulds of wall plate and bottom plate; along the wall plate, casting concrete layered and segmented symmetry. The invention is characterized in that: the casting time difference of nearby two construction sections of nearby two construction layers is less than the coagulation solidifying time of used concrete.

Description

technical field [0001] The invention relates to on-site pouring of building walls, or pouring, in particular to continuous pouring of wall plates and bottom plates in liquid storage structures. Background technique [0002] In the concrete construction of the liquid storage structure in the past, the wall plate and the bottom plate are generally constructed separately, that is, if the wall plate is to be poured, the formwork of the wall plate and concrete pouring can only be carried out after the concrete of the bottom plate reaches a certain strength. At the same time, in order to ensure that the construction joint between the wall plate and the bottom plate does not leak, the bottom plate and the wall plate of about 200 mm are usually poured as a whole, and the construction joint is left at this position. And the construction joints are made into four forms: groove shape, water-stop metal sheet, step shape, and water-swellable rubber water-stop belt. These methods play a ...
