Hoisting method of hyperbolic water-tower water tank and hoisting device

Abstract

The invention discloses a hoisting method of a hyperbolic water-tower water tank and a hoisting device. The hoisting method comprises the following steps of: firstly, prefabricating a water tank, installing lifting equipment, and starting to lift after a real-load pressure test is qualified; during lifting, firstly, jacking steel beams and driving a steel strand to lift; after a stroke is completed, utilizing a locking anchorage device to clamp the steel strand at a static steel beam, returning oil, then utilizing the locking anchorage device to clamp the steel strand onto a moving steel beam after falling back, thereby completing a hoisting cycle for one time; and repeatly lifting until the water tank is lifted to the position and then fixing. The hoisting device comprises a lifting part, a supporting part and a sling assembly, wherein the lifting part comprises a moving steel beam, a static steel beam and a hydraulic lifting device arranged between the moving steel beam and the static steel beam; and the sling assembly comprises a steel stand. The top of the steel stand penetrates through the moving steel beam and the static steel beam and is clamped on the steel beams through the locking anchorage device, and the bottom of the steel stand is connected with the water tank. The construction method and the device are simple in operation and have the advantages of low cost, low labor strength, low energy consumption, strong safety and reliability and good quality of construction.

Description

technical field [0001] The invention relates to a water tower construction method and a used construction device, in particular to a water tower water tank hoisting method and a used hoisting device. Background technique [0002] Water tower is a traditional water storage structure, which plays an important role in basic construction, especially in special industries such as iron and steel and non-ferrous smelting that require a large amount of water storage for backup. With the advancement of science and technology and the development of economy, the design level of construction engineering and people's requirements for aesthetics are constantly improving. The appearance of water towers has also developed from British style, inverted cone shell shape, spherical shape to hyperbolic shape. In the construction process of water towers, it has always been the goal pursued by engineers and technicians to safely, economically and efficiently locate and install large-tonnage hyperb...

AI Technical Summary

Problems solved by technology

[0005] (1) Scaffolding rises with the increase of the height of the water tower support tube, the erection workload is heavy, the material consumption is high, the construction investment is large, and the work efficiency is low;

[0006] (2) The vertical transportation route is long, seriously affecting the construction period;

[0007] (3) There are many safety hazards in high-altitude operations. In case of severe weather such as strong winds, construction cannot be carried out;

[0008] (4) The hyperbolic water tank has a large volume and complex shape, and it is difficult to control various construction parameters when working at heights;

[0009] (5) Concrete pouring intervals are long, high-altitude maintenance is difficult, and there are hidden dangers in the quality of the project, so it is difficult to ensure the impermeability requirements of the water tank

[0011] (1) When installing the boom assembly, due to the large self-weight of the boom assembly itself, the self-weight of the water tank is increased, which requires the use of a high-power hydraulic lifting device, which increases the initial investment of the hoisting equipment and the energy consumption during the hoisting process ;

[0012] (2) During the working process of the boom assembly, not all the booms participate in the stress. Since the rod replacement operation needs to be performed in sequence, it is necessary to increase the labor intensity of the labor force and the hoisting operators, which limits the large-tonnage water tower. hoisting;

[0013] (3) The loading, unloading and transportation of boom components is relatively large, which indirectly increases the construction cost
