Abstract

The invention provides a method for safely hoisting and lowering a ground-connecting wall steel cage, which belongs to the technical field of construction; the invention uses the main crane and the auxiliary crane to cooperate with hoisting, and adds two vertical lifting points to the auxiliary crane, which can effectively ensure that the steel cage is installed in During the lifting and hoisting process, there will be no large deflection and deformation, and there will be no problems of cracking of the weld seam and overall falling apart; the invention adopts an iron pole to connect the wire rope of the hook and the wire rope of the hanging cage, which can effectively ensure that the steel cage is hoisted during the hoisting process. In addition, the present invention is welded with lifting bars, lifting point pressure bars, support bars, and lifting point bars at the positions of the lifting points, and a plurality of groups of temporary laying bars are welded on the steel cage. During the hoisting process, it can avoid direct contact with the reinforcement cage, ensure the integrity of the reinforcement cage, and ensure the construction quality of the reinforcement cage.

Description

technical field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a method for safely hoisting and lowering a ground-attached wall steel cage. Background technique

[0002] The underground diaphragm wall is a long and narrow deep groove excavated along the peripheral axis of the deep excavation project under the condition of mud wall protection. The steel cage is suspended in the groove, and then the underwater concrete is poured by the conduit method to form a unit groove section. In this way, a continuous reinforced concrete wall is built underground, that is, the underground diaphragm wall, which is used for water interception and anti-seepage. , load-bearing, water-retaining structure.

[0003] There are three ways to hoist the reinforcement cage in the ground connection wall groove. The first method is to install the steel reinforcement cage vertically above the groove after the ground connection wall is formed i...
