The invention discloses an anti-seismic drainage gravel pile with an inverted filter structure and a construction method of the anti-seismic drainage gravel pile. The anti-seismic drainage gravel pile with the inverted filter structure comprises a gravel pile body and an inverted filter structure, the inverted filter structure wraps the outer side of the gravel pile body, the inverted filter structure comprises five layers of structures which are arranged in a stacked mode, the five layers of structures comprise a first stress layer, a first protection layer, an inverted filter layer, a second protection layer and a second stress layer which are sequentially arranged from inside to outside, and the five layers of structures are connected into a whole. According to the anti-seismic drainage gravel pile with the inverted filter structure, the problem of clogging caused by the fact that fine particles enter the gravel pile can be effectively solved, meanwhile, high permeability of the pile body is guaranteed, lateral deformation of the pile body is smaller, and the strength and rigidity of the pile body are higher.
本发明公开了带反滤结构的抗震排水碎石桩及其施工方法。所述带反滤结构的抗震排水碎石桩，包括：碎石桩桩体；反滤结构，其包裹于所述碎石桩桩体的外侧，所述反滤结构包括层叠设置的五层结构，其中，所述五层结构包括从内向外依次设置的第一受力层、第一保护层、反滤层、第二保护层和第二受力层，所述五层结构之间彼此连接成为一个整体。本发明所提供的带反滤结构的抗震排水碎石桩可以有效解决细颗粒进入碎石桩引起的淤堵问题，同时保证桩体的高渗透性，使得桩体侧向变形更小、桩体强度和刚度更大。
