Bridge pile foundation reinforcement cage center centering and positioning device

Abstract

The invention relates to the technical field of centering devices, and discloses a bridge pile foundation reinforcement cage center centering and positioning device. The centering and positioning device comprises a pile hole, a reinforcement cage is movably mounted in the pile hole, a predetermined support is fixedly mounted at the top of the pile hole, a target midpoint is arranged at the centerpoint of the predetermined support, two telescopic fixed-point rods are movably mounted at the top of the reinforcement cage, and a mounting through hole is fixedly formed in the center of each telescopic fixed-point rod. According to the bridge pile foundation reinforcement cage center centering and positioning device, the device is temporarily fixed to the top of the reinforcement cage, the twotelescopic fixed-point rods are used for determining the center point of the reinforcement cage, then a measuring connecting line in a display floating block penetrates through the mounting through hole and extends into the reinforcement cage, then the measuring connecting line is connected with a measuring plumb bob through a connecting column head, and the length of the measurement connecting line is properly adjusted through a storage turntable, so that the display floating block can float on the surface of mud.

Description

technical field [0001] The invention relates to the technical field of centering devices, in particular to a centering and positioning device for the center of a bridge pile foundation reinforcement cage. Background technique [0002] The main function of the reinforcement cage is the same as that of the vertical reinforcement of the column. It mainly supplements the compressive and non-shearing performance of the pile foundation concrete. To restrain the effect, so that it can withstand a certain axial tension, in the construction of bridges and culverts or high-rise buildings, according to the design requirements for pile foundation construction, pile foundation construction methods are percussion drilling, rotary excavation, etc., and the hole depth reaches the design Reinforcement cages are then lowered to the pile holes, and then the conduits are inserted for concrete pouring. [0003] In the prior art, due to the weather and special conditions during construction, the...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a centering positioning device for the center of the reinforcement cage of the bridge pile foundation, which has the advantages of being convenient for locating the center point of the reinforcement cage covered by mud, and solves the problem that the construction personnel cannot observe the center point of the reinforcement cage Whether it is aligned with the center point of the drilled hole will affect the subsequent construction, and when the deviation is serious, it will cause huge losses.
