Island type ancient tree protection supporting structure and construction method
The invention discloses an island type ancient tree protection supporting structure and a construction method. The supporting structure comprises a plurality of nonreinforced piles and a plurality of reinforced piles; the nonreinforced piles and the reinforced piles are arranged adjacently, and the adjacent nonreinforced piles and reinforced piles are meshed with each other to form annular closed secant piles; annular closed top beams are further arranged at the tops of the secant piles; and a convex hexadecagonal supporting system composed of two layers of supporting steel pipes is arranged on the inner side of each top beam. The construction method comprises the steps that the positions of the meshed piles are determined, and holes are drilled in the determined positions; secant pile pouring construction is conducted at the drilled positions; the top beams are manufactured, and embedded steel plates are manufactured on the top beams; the supporting steel pipes are welded to the embedded steel plates; checking and accepting are carried out; a foundation pit on the periphery of the scent piles is excavated in a sectioned mode, and annular closed waist beams are manufactured in a sectioned mode; and the foundation pit on the periphery of the secant piles is excavated to the preset depth According to the island type ancient tree protection supporting structure and the construction method, the structure is stable, instability can be prevented in deep foundation pits, and the island type ancient tree protection supporting structure further has a good waterproof effect.
本发明公开了一种孤岛式古树保护支护结构及施工方法，其中支护结构包括多个素桩以及多个荤桩；素桩与荤桩相邻设置，且相邻的素桩与荤桩之间相互咬合形成环形闭合的咬合桩；咬合桩的顶部还设置有环形闭合的冠梁；冠梁内侧设置有两层支撑钢管组成的凸十六边形的支撑体系。施工方法包括：确定咬合桩的位置，并在确定的位置上打孔；在打孔处进行咬合桩灌注施工；制作冠梁，并在冠梁上制作预埋钢板；将支撑钢管与预埋钢板焊接；检查验收；对咬合桩外围基坑分段开挖，并分段制作环形闭合的腰梁；将咬合桩外围基坑挖至预设深度。本发明的孤岛式古树保护支护结构及施工方法其结构稳定，能在较深的基坑中防止失稳，且其还具有良好的防水效果。
