Inverted filter construction device and inverted filter construction method
The invention provides an inverted filter construction device and an inverted filter construction method, and relates to the technical field of pile foundation retaining wall structures, the inverted filter construction device comprises a traction pipe and a pore-forming wall protection pipe, the inner wall of the second end of the pore-forming wall protection pipe is provided with an inner protrusion, and the inner protrusion forms a limiting ring; the second end of the traction pipe is inserted into the pore-forming wall protection pipe from the first end of the pore-forming wall protection pipe, the second end of the traction pipe is provided with a conical tip body, the conical tip body abuts against the limiting ring, and the conical tip body protrudes out of the lower end of the pore-forming wall protection pipe. According to the inverted filter body construction device, the traction pipe and the pore-forming wall protection pipe are inserted into the joints of the sheet piles in a matched mode, the filter material bags are inserted into the pore-forming wall protection pipe, the filter material bags are filled with sand or gravel mixtures, the inverted filter bodies are formed at the joints of the sheet piles, and the inverted filter bodies have water permeability and can effectively reduce the difference between the internal water head and the external water head of a retaining wall; and the inverted filter body is of a flexible structure, so that the deformation coordination capability is high.
本发明提供了一种反滤体施工装置及反滤体施工方法，涉及桩基挡墙结构的技术领域，该反滤体施工装置包括牵引管和成孔护壁管，在所述成孔护壁管的第二端的内壁具有内凸起，所述内凸起形成限位环；所述牵引管的第二端从所述成孔护壁管的第一端插入到所述成孔护壁管内，所述牵引管的第二端具有锥尖体，所述锥尖体与所述限位环抵接，且所述锥尖体从所述成孔护壁管的下端凸出。本发明提供的反滤体施工装置的牵引管和成孔护壁管配合插入到板桩接缝处，通过将滤料袋插入到成孔护壁管内，在滤料袋内填充砂或砂石混合料，使板装接缝处形成反滤体，该反滤体具有透水性，可以有效降低挡土墙的内外水头差；且反滤体为柔性结构，变形协调能力强。
