The invention relates to the technical field of pile head breaking, and discloses a method for breaking pile heads of large-diameter occlusal piles. The protection area and the pipeline protection area, the steps are as follows: S11, the pouring conduit uses the conduit lowering hole to guide and correct the center, and lowers it to the bottom of the hole for concrete pouring; S12, when the overfilled concrete and the hole bottom mud carried are lowered from the conduit When the gap between the hole and the wall of the pile hole overflows upwards, the pouring is completed; S13, take out the pouring conduit; S14, form the pile body, remove and recover the main body of the device; S15, break the pile head structure on the top of the pile body. The method provided by the technical proposal of the present invention is convenient for removing the pile head of a large-diameter occlusal pile, which is easy for subsequent pile head removal work, and the main body of the device can also be reused, thereby reducing the construction cost.
Description
technical field [0001] The patent of the present invention relates to the technical field of pile head removal, in particular, to a method for removing pile heads of large-diameter occlusal piles. Background technique [0002] In the pile foundation engineering in the field of construction, reinforced concrete piles have the characteristics of stable quality and wide application. The grouting height should exceed the design elevation of the pile top by 0.5 to 1.0m, and the part of the pile body structure exceeding the design elevation of the pile top is called the pile head. The work of chiseling and removing the concrete at this part of the pile head is called "breaking the pile head". [0003] In order to achieve the purpose of breaking the pile head concrete without causing damage to the pile body, isolation sleeves are often used to isolate the pile head anchor (segment) steel bars, added pipes (acoustic tubes, side slope pipes, etc.) from the pile head concrete , The ...
