Soil and water Conservation method of shoulder and band drainage device used for the method

Abstract

The drainage band has in the surface several parallel lengthwise capillary channel mouths and circular drainage channels, and water is sucked from the mouths to the channels by means of capilarity and is drained by means of the water level difference in the channels. In the part of the drainage band without drainage channel, metal wires, synthetic wires or reinforcing parts are embedded longitudinally. The drainage band has on its two sides lapping parts for connecting with the adjacent bands.

Description

technical field [0001] The present invention is an additional invention of No. 86101268 "drainage method and belt-shaped drainage member used in the method" of the previously approved patent application, especially a kind of device that provides the same purpose as the previous case and is more resistant to tension and workability Ribbon drain. Background technique [0002] In the parent case No. 86101268, the inventor once disclosed a drainage method and a strip drainage member suitable for water and soil conservation on hillsides, underground drainage of orchard farmland, drainage systems such as tunnels, roadbeds, and building basements. The effect is to absorb the water in the soil from the mouth of the drainage ditch of the drainage device, and use the drop at both ends of the enlarged ditch and the local siphon force to promote water absorption and collect it for discharge. After trial-manufacturing and testing of this kind of drainage fittings, the following problems...

AI Technical Summary

Problems solved by technology

After trial-manufacturing and testing of this kind of drainage fittings, the following problems were found, which need to be improved: (1) Because the drainage fittings are in the shape of thin strips, the area occupied by the hollow part of the cross-section is quite large, often exceeding the solid part. The tensile strength is small, but it is broken or the groove is deformed, which is difficult for high-speed and long-dimension continuous production; in use, the tensile structure of the entire belt body is weak and easy to be pulled apart

(2) When the drainage parts need to be connected horizontally, it is quite difficult. It is inconvenient and inaccurate to use the connecting parts, which will affect the construction work; at the same time, when buried in the soil, the frictional grip of the soil is small, and relative sliding is easy to occur
