The disadvantages of this method are: ① During the concrete pouring process, it is easy to cause the steel cage to float up, and the height deviation of the steel cage is too large; the connection between the hanging bar and the steel cage is usually welded, and the cage is often dropped due to welding quality problems, and the welding speed is slow ; ②Usually the hanging bars and steel cages cannot be reused after welding, resulting in waste of materials; ③There are no other guarantee measures after the steel cages are centered, and the conventional platform is easy to disturb the position of the steel cages during the pouring process. Displacement of reinforcement cage and jamming of conduit; ④Conventional use of mud to form hole pile foundation site is wet and slippery, and the safety factor is low

The invention provides a pile foundation reinforcement cage installation position control device and a concrete pouring construction platform. The reinforcement cage installation position control device comprises a reinforcing bar connecting rod and a centering adjusting steel pipe. The bottom of the reinforcing bar connecting rod is connected with the top of a reinforcement cage. Working groovesare formed in the two ends of the centering adjusting steel pipe. The reinforcing bar connecting rod penetrates through the working grooves. The two ends of the centering adjusting steel pipe abut against the inner wall of a guard cylinder. The concrete pouring construction platform is located on the ground and located above the reinforcement cage installation position control device. A reinforcing bar connecting rod hole is reserved in the concrete pouring construction platform. The top of the reinforcing bar connecting rod is arranged in the reserved reinforcing bar connecting rod hole in apenetrating mode and fixed. The pile foundation reinforcement cage installation position control device has high practicability, the reinforcing bar connecting rod and the centering adjusting steel pipe can be reused, the position of the reinforcement cage can be effectively controlled, and meanwhile, the concrete pouring construction platform can effectively prevent guide pipe displacement in theconcrete pouring process.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a position control for installation of a reinforced cage of a bored pile and a fixed platform for combined construction of concrete pouring. Background technique [0002] At present, the installation elevation control of most bored pile reinforcement cages adopts the measurement of the length of the hanging bar (the length is the difference between the ground elevation and the design elevation of the reinforcement cage) to control the installation elevation. The disadvantages of this method are: ① During the concrete pouring process, it is easy to cause the steel cage to float up, and the height deviation of the steel cage is too large; the connection between the hanging bar and the steel cage is usually welded, and the cage is often dropped due to welding quality problems, and the welding speed is slow ; ②Usually the hanging bars and steel cages cannot be reused af...
