Semi-fabricated ultra-deep laminated water storage tank and construction process

Abstract

The invention relates to a semi-assembly type ultra-deep laminated water storage tank and a construction technology. The semi-assembly type ultra-deep laminated water storage tank comprises a prefabricated UHPC inner wall plate located on the innermost side, and an outer formwork is supported on the outermost side of the UHPC inner wall plate; the UHPC inner wall plates are connected through the anchor cables to form the UHPC inner wall plate assembly with the rectangular or circular cross section. The profile steel is evenly distributed on the periphery of the UHPC inner wall plate, and the profile steel and the UHPC inner wall plate are of an integrated or detachable structure. A steel reinforcement framework is bound between the outer side of the profile steel and the outer template; concrete is poured between the UHPC inner wall plate and the outer formwork to form an SRC outer wall plate; the tail end of the UHPC inner wall plate is poured in the reinforced concrete bottom plate, and a post-pouring groove is formed in the reinforced concrete bottom plate; and a concrete cushion layer is arranged at the bottom of the reinforced concrete bottom plate, so that the UHPC-SRC superimposed water storage tank is formed. The concrete has the outstanding advantages of being high in lateral bearing capacity, good in crack resistance, high in rigidity, high in corrosion resistance, good in durability and large in capacity, and is particularly suitable for storing liquid with high corrosivity.

Description

technical field [0001] The invention belongs to the technical field of underground water storage, and in particular relates to a semi-fabricated ultra-deep superimposed water storage tank and a construction process. Background technique [0002] Nowadays, with the rapid development of my country's urbanization process, the rapid growth of urban population, people's living standards have improved significantly, and domestic water consumption and industrial and agricultural water consumption have been increasing day by day, which has brought about a substantial increase in water supply and drainage, especially Many industrial and agricultural production and daily life sewage cannot be discharged at will, and need short-term or long-term storage. Therefore, the construction of a large number of water supply and drainage facilities is a top priority, which makes the construction projects of urban sewage treatment plants and water supply plants increase day by day. The pool is th...

Problems solved by technology

[0003] As far as the current design and usage are concerned, cast-in-place concrete is still the main method for building pools. The construction technology of cast-in-place reinforced concrete has been widely used in various pool projects. However, due to its limited size, long construction period, and difficult control of construction technology The amount of concrete work is large, which makes the consumption of manpower, material strength, machinery and tools too large, the cost is high, and the management of the construction site is difficult.

Especially with the development of the capacity of the pool to a large direction, the contradiction of land use is intensified, the traditional reinforced concrete pool is difficult to meet the development needs of modern society, and the demand for large ultra-deep and ultra-long pools is obtained. Therefore, it is urgent to update the structural forms of various traditional pools , design a structure type with better performance
