Problems solved by technology

Although this construction method can safely hoist the steel cage, the truss used for lifting the steel cage cannot be taken out after the steel cage is put into the groove, and there is no possibility of repeated use. At the same time, the power consumption of the truss is equivalent to the number of welding electrodes Larger, and increase the labor intensity of welders, it is more likely to prolong the construction period

Abstract

The present invention relates to tunnel construction technology, and is especially reinforcing bar cage hoisting process for canal wall construction. The reinforcing bar cage hoisting process has longitudinal truss, transverse truss and reinforcing bar cage connected detachably. The present invention can ensure the hoisting rigidity of the reinforcing bar cage while realizing the repeated use of the trusses.

Description

technical field [0001] The invention relates to tunnels, in particular to a method for hoisting a reinforcement cage used in tunnel wall construction during tunnel engineering construction. Background technique [0002] The groove wall construction method has been widely used in tunnel engineering construction all over the world due to its unique advantages. In recent years, Beijing, Shanghai, Guangzhou, Tianjin, Shenzhen and other large and medium-sized cities in China have started the construction of large-scale rail transit systems with subways as the main body. my country has made great progress in the construction technology of groove walls. Fabrication and hoisting of reinforcement cages is an important link in the construction process of the tank wall. A practical and reasonable method of fabrication and hoisting of reinforcement cages can make the entire construction process of the tank wall faster, more effective, safer and more economical. [0003] In the construc...
