Uncover the anti-seepage secret of Vulcan Mountain Raytheon Mountain Hospital: "Two Geotextile and One Geomembrane" construction process, find out!

                    Two layers geotextile and one layer geomembrane construction


Although the Vulcan and Raytheon hospitals were built as temporary hospitals to fight the epidemic, they are not “temporary” at all in wastewater treatment: fully enclosed operation, and pumped to the municipal pipe network after the third-level liquid chlorine disinfection; press under the entire base HDPE geomembrane is laid as standard in the landfill, as if wearing "protective clothing", the rainwater is collected and disinfected completely, and no drop of sewage is allowed to enter the ground!

The picture shows that the Vulcan Hill Hospital is laying geotextile and HDPE Geomembrane. The 30,000 square meter HDPE Geomembrane puts on "protective clothing" for the 25,000 square meter underground foundation of the Vulcan Hill Hospital to ensure that no drop of sewage enters the ground.


The hospital refers to the standard of the landfill, and the construction structure is "two geotextiles and one geomembrane" structure, which is "two layers of geotextile and one layer of HDPE geomembrane". On the leveled ground, lay 20 cm thick sand, and embed with the pipeline pre-embedded construction, then will be laid on the "two geotextile and one geomembrane"-two layers of geotextile and a layer of HDPE geomembrane, and then Laying 20 cm sand, has a strong anti-seepage effect.

The geotextile used in this hospital is 600g / m2 polyester filament geotextile, and the HDPE geomembrane is 2.0mm double textured surface geomembrane.

HDPE geomembrane construction process


HDPE geomembrane, full name high-density polyethylene geomembrane, is a polyethylene black resin (using high-density polyethylene as the main component) with a certain proportion of carbon black masterbatch, anti-aging agent, anti The oxidant, ultraviolet absorber, stabilizer, etc. are blow-molded by single-layer, double-layer, and three-layer co-extrusion technology. It is a kind of good anti-seepage effect, acid and alkali resistance, corrosion resistance, high tensile strength, and long service life. Impervious material. It is suitable for engineering anti-seepage, anti-seepage of sewage pool, anti-seepage of landfill, anti-seepage of tailings disposal site, anti-seepage of solid waste landfill and other projects.
