Problems solved by technology
[0004] 2. There are round holes on the tray that match the diameter of the plastic casing to support the positioning of the plastic casing and the main reinforcement. The defect is that the round holes on the tray correspond to the main reinforcement one by one, which cannot be used for different piles. , and affected by the actual construction technology, there may be deviations in the position of the main reinforcement
[0005] 3. There is a problem that the pouring process cannot guarantee the quality of the pile head

The invention discloses a pile head isolation device and a construction operation method thereof in the technical field of concrete pile construction. The device comprises a tray and a sleeve arranged on the tray; an annular groove is provided on the tray, and a plurality of hollow bolts are installed in the annular groove. The lower end of the sleeve is fixedly connected with the hollow bolt; the center of the tray is provided with an opening and a rubber plate for the pouring pipeline to pass through; a number of support rods for supporting the tray are fixedly welded on the side wall of the main rib, and the outer side of the tray is sleeved with The protective tube, the inner wall of the protective tube is provided with a tray positioning device for pressing the edge of the tray to achieve positioning and installation, the present invention can achieve the purpose of completely isolating the effective pile head from the invalid pile head when breaking the super-filled concrete pile head, and is applicable to It has good compatibility in the construction of concrete piles with different reinforcement cage structures, and can accurately position the tray at the specified effective pile head elevation, which can ensure the accuracy of the pile head elevation, thereby improving the quality of the pile head.
Description
technical field [0001] The invention relates to the technical field of concrete pile construction, in particular to a pile head isolation device and a construction operation method thereof. Background technique [0002] There are some pile head breaking devices in the prior art, which solve the problems of tight grip of the concrete and incomplete separation of the concrete and the main reinforcement, and reduce the difficulty of manual construction. In the later stage, the problem of large construction volume was solved. On April 16, 2019, the invention patent announcement number of "a bored pile head isolation device and its use method" was announced as: CN107587625A. The isolation device uses a plastic casing to wrap the steel bar to achieve the steel bar in the invalid pile head. Purpose of separation from concrete. On October 16, 2018, the patent publication number of "Isolation Device for Bored Cast-in-Situ Pile Heads" was published: CN207974103U. The above two pate...
