Anti-clogging composite drainage plate with back-flushing function
The invention discloses an anti-clogging composite drainage plate with a back-flushing function. The anti-clogging composite drainage plate comprises an outer filter membrane, an inner filter membrane, a fiber floc interlayer and a drainage plate core. The fiber floc interlayer is filled between the outer filter membrane and the inner filter membrane to form composite breathable plates, and the front surface and the back surface of the drainage plate core are covered with the composite breathable plates respectively to form the breathable composite drainage plate with a brand new structure. In the application process, the problem of soft soil clogging in the drainage process is solved by adopting a process of alternating vacuum preloading drainage and positive pressure back-flushing clogging removal. A corrugated plate formed by stamping a thin plate is adopted as the drainage plate core, so that the rigidity of the drainage plate is improved, and the problem of bending deformation of the drainage plate is solved. The anti-clogging composite drainage plate has the advantages of simple structure, convenience in use and high drainage efficiency.
本发明公开了一种反冲气防淤堵的复合式排水板，它包括外层滤膜、内层滤膜、纤维絮体夹层及排水板板芯，本发明采用将纤维絮体夹层填充于外层滤膜及内层滤膜之间构成复合透气板，并将复合透气板分别覆盖在排水板板芯的正反两个面上，构成全新结构的、可透气的复合式排水板。在应用过程中，采用真空预压排水与正压反冲清除淤堵相交替的工艺，克服了排水过程中软土淤堵的问题。采用薄板冲压而成的波纹板作为排水板板芯，提高排水板的刚性，解决排水板弯折变形的问题。本发明具有结构简单，使用便捷，排水效率高的优点。
