A method of manufacturing a large-diameter pile foundation reinforcement cage

Abstract

The invention discloses a large-diameter pile foundation reinforcement cage manufacturing method. The method includes the steps that firstly, a large-diameter pile foundation reinforcement cage manufacturing region is arranged; secondly, longitudinal main ribs are machined; thirdly, the first joint of a reinforcement cage is manufactured; fourthly, a standard joint of the reinforcement cage is manufactured; fifthly, the first joint of the reinforcement cage is pushed to a track vehicle, the first joint of the reinforcement cage is conveyed to the reinforcement cage storage region through the track vehicle, and outer hoops and spacer bars of the first joint of the reinforcement cage are welded; sixthly, the second joint of the reinforcement cage is conveyed to a first manufacturing platform center through the track vehicle to serve as the locating rebar cage for manufacturing of the next joint of the reinforcement cage, and the fourth step is repeated to finish manufacturing of other standard joints; and seventhly, a tail joint of the reinforcement cage is manufactured. By the adoption of the method, the butt joint accuracy of the joints of the reinforcement cage is guaranteed, and the error is very small.

Description

technical field [0001] The invention relates to a method for manufacturing a reinforcement cage, in particular to a method for manufacturing a reinforcement cage for a large-diameter pile foundation. Background technique [0002] With the acceleration of economic construction and the increase of transportation road load, the existing transportation roads are difficult to meet the transportation capacity required by the growing economic speed, so there are large-scale road and bridge constructions, especially in some areas where the geological conditions are too harsh. Poor, the current construction of roads and bridges requires high standards, which are reflected in the large traffic flow and large vehicles, and stricter requirements for foundation settlement. Therefore, more pile foundations are designed to cope with complex geological conditions. The diameter of the pile foundation is super large and the depth is super Deep, especially a depth of 40 to 50 is more common. ...

AI Technical Summary

Problems solved by technology

Pile foundation reinforcement cages are generally made of ordinary steel plates according to the 1 / 3 arc of the reinforcement cage radius to make longitudinal reinforcement positioning molds, and the blanked main reinforcements are placed in the positioning grooves of the tire molds according to the length of the configuration for adjustment and alignment processing. After 1 After the installation of the / 3 side is completed, use a crane to roll over, and then repeat the above steps in order to complete the remaining parts of the construction. After all the processing is completed, use the lifting system to quickly transfer the finished product to the stacking position. During the production process, the lifting system needs to cooperate many times. The production is time-consuming and laborious, the efficiency is low, the tire mold processing cost is high, and only one diameter steel cage can be used to make it, which cannot be recycled, and the economy is poor, and the steel cage made in this form is usually welded on site. The segment is put into the hole, the butt joint accuracy of the steel cage is poor during the butt joint process, the welding quality of the joint point is not easy to control, and it is time-consuming and laborious, and the operation is inconvenient
