Description

Anti-seepage geomembrane pipe penetrating sealing piece

Technical Field

The utility model belongs to the technical field of anti-seepage engineering, and particularly relates to an anti-seepage geomembrane pipe penetrating sealing element.

Background

In urban garbage storage sites, landscape dams and the like, people widely arrange geomembranes and impermeable membranes to prevent stored water from seeping outwards or garbage from seeping into soil to destroy the ecological environment, but the widely arranged geomembranes and ubiquitous water and air delivery PE pipelines form inevitable intersection, and the impermeable connection at the intersection of the geomembranes and the PE pipelines becomes the key of project success and failure and also becomes a difficult problem which technicians must face.

The current method for crossing the geomembrane and the PE pipeline is to use manual fusion welding, namely, holes are formed in the geomembrane according to the diameter of a PE pipe, the geomembrane is arranged and then the pipe is penetrated, and then hot air hot melting sealing is adopted, and sometimes asphalt is coated again for reinforcement. The method is simple and easy to learn, and convenient and quick to operate, but the inherent defects are very obvious, and the method mainly comprises four points: first, the position and shape of the opening are not correct. An operator can only measure the orthographic projection of the pipeline by measuring the pipe in advance, holes are cut according to the orthographic projection, in the actual arrangement, the ground of the garbage storage yard or the river channel is an irregular inclined plane, the geomembrane is obliquely crossed with the pipeline, the shape of the geomembrane is difficult to control when the holes are cut, the phenomenon of meat leakage mostly occurs, the film can only be cut again in the later period to repair the holes, the operation difficulty is high, and the welded parts are cracked more. Secondly, the difference between the thicknesses of the geomembrane and the pipeline wall is very large, the geomembrane and the pipeline wall are influenced by thermal stress change and environmental temperature after welding, and the intersection is easy to crack and is not easy to find. The malady is most obvious in the cold season in the north. Thirdly, the pipe wall of the PE pipe part is ablated during hot melting, and the pressure bearing of the pipeline is reduced to a certain degree. Fourthly, the PE pipeline penetrates through the near-ground side of the geomembrane, the equipment lacks operation space, and welding is difficult.
