Hoop-shaped opposite-pulling self-locking anchoring support construction method for secant piles in ancient tree protection area of deep foundation pit
The invention relates to the technical field of foundation pit supporting, and discloses a deep foundation pit ancient tree protection area secant pile hoop-shaped opposite-pulling self-locking anchoring supporting construction method which comprises the following steps: 1) determining a protection area according to a design construction drawing, and enabling an ancient tree to be located in the middle of the protection area; a plurality of secant piles are constructed on the periphery of the protection area, a continuous enclosure structure is formed by the secant piles in the arrangement direction of the secant piles, and an opening is formed in the end of the enclosure structure; (2) a top beam and an alignment beam are constructed on the enclosure structure, and the enclosure structure, the alignment beam and the top beam are combined into a whole; (3) an upper area is formed through excavation construction, the periphery of the enclosure structure is exposed in the upper area to form an upper reinforcing face, and a self-locking anchoring structure is constructed on the upper reinforcing face; (4) a lower area is formed through excavation construction, the periphery of the enclosure structure is exposed in the lower area to form a lower reinforcing face, and a self-locking anchoring structure is constructed on the lower reinforcing face; and (5) downward excavation is conducted to the set depth of the deep foundation pit.
本发明涉及的基坑支护技术领域，公开了深基坑古树保护区咬合桩箍形对拉自锁锚固支护施工方法，1)、根据设计施工图，确定保护区，古树位于保护区的中部；在保护区的外周施工多个咬合桩，沿着多个咬合桩的排列方向，多个咬合桩形成一道连续的围护结构，围护结构的端部形成有开口；2)、在围护结构上施工形成冠梁以及对位梁，围护结构、对位梁以及冠梁结合为一体；3)、开挖施工形成上部区域，围护结构的外周显露在上部区域中形成上部加固面，在上部加固面上施工自锁锚固结构；4)、开挖施工形成下部区域，围护结构的外周显露在下部区域中形成下部加固面，在下部加固面上施工自锁锚固结构；5)、朝下开挖至深基坑设定深度。
