High-protection flexible vertical anti-seepage system

Abstract

The invention discloses a high-protection flexible vertical anti-seepage system which comprises a plurality of locking column modules which are arranged at intervals, and each locking column module comprises a matching groove or a lock catch embedded part which is arranged in the length direction of the locking column module; an HDPE membrane group which comprises a first HDPE geomembrane and locking fasteners fixed at the two ends of the first HDPE geomembrane, and the locking fasteners are used for being connected to the matching grooves or the locking embedded parts; the two ends of the HDPE membrane group are respectively connected to the two adjacent locking column modules. According to the high-protection flexible vertical anti-seepage system, the depth of a bentonite slurry anti-seepage wall can be achieved, the bottleneck problem that the depth of a lower membrane of a current domestic HDPE geomembrane anti-seepage wall cannot exceed 30 m is substantially solved, and a choice which is high in safety, convenient to construct and high in reliability is provided for the field of HDPE geomembrane anti-seepage walls.

Description

technical field [0001] The invention relates to technical fields such as solid waste landfill, petrochemical industry, water conservancy engineering, and urban underground engineering, and in particular relates to a high-protection flexible vertical anti-seepage system used in related fields. Background technique [0002] Existing vertical anti-seepage systems generally use concrete anti-seepage walls, clay-bentonite mud anti-seepage walls, and HDPE geomembrane anti-seepage walls. Among them, HDPE geomembrane anti-seepage walls can easily achieve low permeability although the process is complicated. In addition, its integrity, corrosion resistance, and durability are relatively good, and it has gradually become the future development direction of vertical anti-seepage technology. [0003] For example, the Chinese patents whose publication numbers are CN102444145B and CN207143911U, at present, the HOPE geomembrane anti-seepage wall generally consists of porous connection devi...

AI Technical Summary

Problems solved by technology

The locking column module itself has high strength, bending resistance, and anti-seepage coefficient, and it is used as an intermediate connection hub in the entire vertical anti-seepage system, which can effectively overcome the connection problems caused by excessive laying depth. Problems of instability and deformation of joints, which in turn allow for higher laying depths compared to existing technologies
