Perpendicularity regulating method for foundation cast-in-place pile steel bar cage of power transmission iron tower

Abstract

The invention relates to a perpendicularity regulating method for a foundation cast-in-place pile steel bar cage of a power transmission iron tower. According to the method, the lower rend of each vertical steel bar of the steel bar cage is respectively provided with a perpendicularity regulator, each perpendicularity regulator comprises a clamp sheet, an arc-shaped main buckle rod, a sharp head metal hammer, a heavy hammer shaft, a clamp sheet shaft and a steel wire lifting rope, one end of the arc-shaped main buckle rod is movably hinged to the clamp sheet used for clamping the vertical steel bars through the clamp sheet shaft, the other end of the arc-shaped main buckle rod is hinged to the sharp head metal hammer through the heavy hammer shaft, the lower end of the sharp head metal hammer is provided with a sharp head and can freely rotate around the heavy hammer shaft, the sharp head metal hammer and the arc-shaped main buckle rod are connected with the steel wire lifting rope, and the upper end of the steel wire lifting rope extends out of a well opening protection tube. The perpendicularity regulating method is applicable to all perpendicularity regulating work procedures of cylindrical drill holes to the bottom steel bar cage, is suitable for in-site processing, and has the advantages that the installation is simple and convenient, the repeated use can be realized, economy and practicability are realized, and more obvious effects of high speed, convenience, practicability, social benefits and economic benefits can be achieved.

Description

technical field [0001] The invention belongs to the field of cast-in-place piles for foundations of power transmission towers, in particular to a method for adjusting the verticality of steel cages of cast-in-situ piles for foundations of power transmission towers. Background technique [0002] At present, for the cast-in-place piles of the foundation of the transmission line iron tower, using the protective layer pad to correct the verticality when lowering the steel cage will damage the hole wall, and the difficulty of lowering the steel cage is generally not used. Feeling, repeated corrections are easy to occur, and the deviation of the verticality of the steel cage will also affect the overall engineering quality of the pile body. [0003] After searching, no disclosed technology identical with this patent application has been found. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a m...
