Embodiment Construction

[0022] The present invention provides a PE board lining channel. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] The implementation process can be divided into: soil foundation forming, pouring (or prefabricated installation) tooth wall and pier, cushion laying, prefabricated PE plate installation, each part will be explained below.

[0024] see figure 1 It is a structural schematic diagram of the plate of the present invention, as a small unit of the lining, the plates are tightly connected by hot-melt connection, the back surface is provided with ridges (protrusions) 2 intersecting horizontally and vertically, and steel wire mesh sheets 3 are arranged inside , according to the strength calculat...

Abstract

The invention discloses a novel PE plate channel. The plate is made of a high-wear-resistance PE material, a steel wire mesh is arranged in the plate, the upstream face of the plate is a smooth face, and the downstream face of the plate is ridges (protrusions) which intersect longitudinally and transversely so that the strength of the PE plate and the friction force between the plate and a canal base can be increased. The novel channel can be prefabricated and formed in a factory and directly installed on site, the plate units can also be connected in a hot melting mode on site, and all the sections are mechanically connected. According to the novel PE plate channel, the structure is simple, and compared with a traditional concrete lining channel, the novel PE plate channel has the advantages of being good in anti-seepage and anti-freezing performance, low in roughness, resistant to aging, good in toughness, high in deformation adaptability, convenient and rapid to construct and the like.

Description

technical field [0001] The invention relates to the technical field of medium and small canal lining in irrigation areas, in particular to a PE board lining canal. Background technique [0002] In my country, channel lining technology develops very rapidly, especially channels with concrete as lining material are widely used in water conservancy projects and water supply and drainage projects. Compared with earth canals, although concrete-lined canals have greatly improved water delivery efficiency, the ensuing canals have poorer ability to resist frost heave and adapt to foundation deformation, require anti-seepage geotextiles, and have a shorter service life. Problems such as long construction period and uneven construction quality came one after another. It can be seen that the concrete lining channel still has certain limitations. In order to solve these problems, measures such as strengthening the foundation, increasing the concrete grade, and adopting anti-seepage an...
