Nanofiber Waterproof Membrane for River Embankment

Abstract

The invention provides a nanofiber waterproof membrane for a river levee. The nanofiber waterproof membrane comprises a plurality of rectangular main membranes in parallel arrangement, and further comprises seam filling membranes which are arranged between the main membranes and can play sealing and connecting roles, wherein each main membrane comprises a first base layer, a first nanofiber layer and a second base layer which are arranged from bottom to top; each seam filling membrane comprises a third base layer and a second nanofiber layer which are arranged from bottom to top; the two sides of the first base layers and the second base layers extend outwards to form first connecting layer sections and second connecting layer sections; the first connecting layer sections are connected with the third base layers of which the widths are equal to those of the first connecting layer sections; the first connecting layer sections and the second connecting layer sections of the adjacent main membranes are mutually connected; and the second nanofiber layers are slightly wider than the third base layers. The nanofiber waterproof membrane is combined with the nanofiber technology, and is low in preparation cost, excellent in impermeability, long in service life and strong in adaptability to the aquatic and geological environment.

Description

technical field [0001] The invention relates to the technical field of river course anti-seepage, in particular to a nanofiber waterproof membrane for river embankments. Background technique [0002] In the life and production of the city, the embankment plays an important role in regulating the environment and climate of the city. It can effectively improve the local environment and climate, which plays an important role in promoting urban production. In the process of economic development, most city builders conduct research on the flood control and drainage capacity of urban rivers, and carry out projects such as cutting and straightening the rivers. With the continuous construction of water conservancy projects, the structure of urban embankments has undergone great changes. However, in the process of urbanization, a large amount of domestic sewage and industrial wastewater have polluted the river, and many ecological problems have appeared in the river course. Therefo...

AI Technical Summary

Problems solved by technology

[0004] The existing embankment anti-seepage technologies mainly include curtain grouting method, seepage drainage well method, weighted cover method and geomembrane method, among which the implementation of curtain grouting method, seepage drainage well method and weighted cover method is relatively complicated and the seepage prevention ability is limited , and the cost of anti-seepage is high. Compared with these methods, the geomembrane method is relatively economical and affordable, but in the construction of the geomembrane, there are certain requirements for the corresponding water quality and geological environment. When the groundwater level is high and the foundation is soft, it is not suitable to use geomembrane method for construction
