Device and method for preventing alignment offset of pile foundation engineering reinforcement cage

Abstract

The invention provides a device for preventing alignment offset of a pile foundation engineering reinforcement cage. The device comprises a protective cylinder, a support and an image acquisition unit, wherein the image acquisition unit is fixed to the lower portion of the support; a processing unit is electrically connected with a guide rail, a driving unit and the image acquisition unit; the processing unit is further used for matching I0 with L01 and L02 and then continuing to put down the reinforcement cage, and the image acquisition unit is used for acquiring image information of the reinforcement cage every preset time T0 so as to obtain i image data of the reinforcement cage at the i moment; and the I0 is compared with the image information of the reinforcement cage, the telescopic stroke of the first driving unit and the telescopic stroke of the second driving unit are adjusted according to the comparison result, and meanwhile, the putting-down speed of the reinforcement cage is adjusted according to the telescopic stroke adjustment amount. According to the device, the reinforcement cage cannot deviate when being put down, then the reinforcement cage can be always located in the center of a pile hole, and the construction effect is guaranteed; and meanwhile, intelligent control is carried out in an electric control mode, and the construction efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of reinforcement cage alignment, in particular to a device and method for preventing alignment deviation of reinforcement cages in pile foundation engineering. Background technique [0002] The main function of the reinforcement cage is the same as that of the vertical reinforcement of the column. It mainly plays a role in tensile strength. The compressive strength of concrete is high but the tensile strength is very low. It acts as a constraint on the concrete of the pile body so that it can bear a certain axial tension. During the construction of bridges, culverts or high-rise buildings, the foundation may be required to be piled according to requirements. The method is to use machine punching and water mill drilling, and the hole depth meets the design requirements, and then lower the reinforcement cage to the pile hole, and then insert the conduit for concrete pouring. [0003] In addition, when the con...
