Description

Technical Field

[0001] The utility model relates to the field of engineering construction, in particular to an adjustable main reinforcement positioning device for a cast-in-place pile reinforcement cage. Background Art

[0002] Cast-in-place piles are buried deep underground. Ordinary cast-in-place pile steel cages are relatively short and can be tied and formed at one time, and hoisted and placed as a whole. For cast-in-place piles with large bearing capacity, the design pile length is relatively long, which can reach tens of meters or even hundreds of meters. The steel cage must be made in sections and hoisted and connected on site. For processing sites with good conditions, the steel cage can be made on the tire frame as a whole and assembled in sections on site. The main reinforcement can be well aligned. For sites with poor conditions, there is no tire frame to use, so it can only be made in sections and hoisted and assembled on site. However, during the connection process, the main reinforcement positions of the two sections of the steel cage often do not correspond, and the two sections of the steel cage cannot be connected, resulting in the steel cage being dismantled and re-tied, or the main reinforcement being bent and connected, which not only delays the construction period but also affects the quality of the pile foundation construction.
